To determine if the speeds of the runners are in a proportional relationship, compare the ratios of their distances to their times.
Explanation:In order for the speeds of the runners to be in a proportional relationship, their rates of covering distance should be consistent. In other words, the ratios of their distances to their times should be the same or equal.
For example, if Runner A ran 5 miles in 1 hour, and Runner B ran 10 miles in 2 hours, their speeds would be proportional because the ratio of distance to time is the same (5/1 = 10/2 = 5).
So, to determine which runners have proportional speeds, compare the ratios of their distances to their times and see if they are equal.

Final answer:
Runners whose speeds are in a proportional relationship with each other are those who have the same average speed when the distance they run is divided by the time it took them. To find this, we use the average speed formula, which helps compare runners not only on an individual level but also in terms of speed fractions and distributions.
Explanation:
To determine which runners have speeds in a proportional relationship with each other, we need to use the concept of proportional relationships and the formula for average speed, which is calculated by dividing the distance by the time. If the ratio of distances to times for two runners is the same, then their speeds are proportional. For example, Runner A covering a distance of 10 miles in 2 hours and Runner B covering 5 miles in 1 hour both have an average speed of 5 miles per hour, which shows a proportional relationship.
Relating this to the details provided about the runners, for any pair of runners to have speeds that are in a proportional relationship, their speeds must be consistent or equivalent when calculated. The speed in miles per hour can be found by dividing the recorded distances by the recorded times. If multiple runners have the same result when distance is divided by the time, they are in a proportional relationship with each other in terms of speed.

-3x+2y=16
X-2y=-12
Answer:
For the given equations the values of x and y by using substitution method are [tex]x=1[/tex] and [tex]y=\frac{13}{2}[/tex]
Step-by-step explanation:
Given system of equations are
[tex]-3x+2y=16\hfill (1)[/tex]
[tex]x-2y=-12\hfill (2)[/tex]
Solve the given equations by substitution method:
Now (2) implies
[tex]x-2y=-12[/tex]
[tex]x=-12+2y\hfill (3)[/tex]
Now substitute the x value in equation (1)
[tex]-3x+2y=16[/tex]
[tex]-3(-12+2y)+2y=16[/tex]
[tex]36-6y+2y=16[/tex]
[tex]36-4y=16[/tex]
[tex]-4y=16-36[/tex]
[tex]y=-(\frac{-26}{4})[/tex]
[tex]y=\frac{26}{4}[/tex]
Therefore [tex]y=\frac{13}{2}[/tex]
Now substitute the y value in equation (3)
[tex]x=-12+2y[/tex]
[tex]x=-12+2\times \frac{13}{2}[/tex]
[tex]x=-12+13[/tex]
[tex]x=1[/tex]
Therefore [tex]x=1[/tex] and [tex]y=\frac{13}{2}[/tex]

Rebecca has a monthly plan that charges her $45.50 each month for unlimited talk and text. For each gigabyte of data that she uses, she has to pay an additional $5.25. If the cost of her bill is represented by variable C and the number of gigabytes is represented by the variable g, write an equation that represents this situation.
Answer:
C = $5.25g + $45.50
Step-by-step explanation:
The $45.50 is her monthly bill and does not change. The additional fee determines on the amount of gigabytes she used which is undetermined, using the variable g. It cost $5.25 per gigabyte. C is her total/the bill.
Answer:
C = $5.25g + $45.50

AA cash register has only one-dollar bills and five-dollar bills, and no change. There are $6$6 times as many one-dollar bills as five-dollar bills. The total amount in the cash register is $231.
Answer:
There are 126 $1 bills and 21 $5 bills.
Step-by-step explanation:
Given,
Total cash Amount = $231
Solution,
Let the number of $1 bill be 'x'.
And the number of $5 bill be 'y'.
Now according to question, one-dollar bills is six times of five-dollar bills.
So, we can frame it in equation form as;
[tex]x=6y[/tex] ⇒ equation 1
Again according to question, there is only one-dollar bills and five-dollar bills, and no change.
That means the total cash amount is in the form of $1 and $5.
So, we can frame the above sentence in equation form as;
[tex]1\times x+5\times y=231\\\\x+5y=231[/tex]⇒ equation 2
Now substituting the value of x in equation 2, we get;
[tex]6y+5y=231\\\\11y=231\\\\y=\frac{231}{11}=21[/tex]
So, [tex]x=6y=6\times 21=126[/tex]
Hence There are 126 $1 bills and 21 $5 bills.
How many 10s are in a 20

20 ÷ 10
2 whole tens go into 20.
20 ÷ 10 = 2
Answer: 2
This question is asking you to divide 20 by 10. This means:
20 ÷ 10=2
If 10 can go into a number 2 times, it means that 10•2=20. So, since we dont know how many times 10 goes into 20, we divide 20 by 10.

Harry is comparing the cost of a fresh lobster dinner at two different restaurants. The first restaurant charges $15 for the meal, plus $4 per pound for the lobster he picks. At the second restaurant, Harry would pay $3 per pound for the lobster, in addition to $38 for the meal. Harry realizes that, in theory, dinner at both restaurants could cost the same amount if the lobster had a certain weight. How much would Harry pay for his dinner? What is the weight?
Answer:i’m not sure but i think it’s around 10-11 for per pound for the lobsters.
Step-by-step explanation:
15$ + 4per lobster = 19$ and 38$+$3=41 so it should be around that amount of 22
he would pay $107
and it would weigh 23 pounds
Step-by-step explanation:
15+4p=x
38+3p=x
15+4p=38+3p
subtract 3p from both sides
15+p=38
subtract 15 from both sides
p=23
15+4(23)=107
38+3(23)=107

Complete each of the ratios on the table show calculations
Answer:
From left to right:
2, 4, 32
Step-by-step explanation:
Using the one column which is completed, determine the ratio of yellow to blue by reducing to lowest terms.
yellow to blue = 8 to 16
8 and 16 are both divisible by 8. 8/8 = 1 and 16/8 = 2
8 to 16 = 1 to 2
This means there is half as much yellow paint as there is blue paint. If said backwards, there is double the amount of blue paint as there is yellow paint.
In the first two columns, yellow paint is blue paint divided by 2.
4/2 = 2
8/2 = 4
In the last column, blue paint is yellow paint times 2.
16 X 2= 32
All of the ratios yellow to blue are:
2 to 4
4 to 8
8 to 16
16 to 32
2/9x+5=2/3
I have to rewrite the equation so it doesn’t have a fraction
Answer:
2x + 45 = 6
Step-by-step explanation:
(2/9)x + 5 = 2/3 Subtract 5 from both sides
(2/9)x +5-5=2/3-5
(2/9)x = - 4 1/3 Multiply by 9
2x = -13/3 * 9
2x = -39
x = -19.5
==============
I see. You don't want it solved. Multiply by 9 to clear the fractions.
==============
2x + 45 = 6
==============
Solve it now. It should be easier.
2x = 6 - 45
2x = - 39
x = -19.5
how does this polynomial identity work on numerical relationships?
(y + x) (ax + b)
Answer:
Let us take 'a' in the place of 'y' so the equation becomes
(y+x) (ax+b)
Step-by-step explanation:
Step 1:
(a + x) (ax + b)
Step 2: Proof
Checking polynomial identity.
(ax+b )(x+a) = FOIL
(ax+b)(x+a)
ax^2+a^2x is the First Term in the FOIL
ax^2 + a^2x + bx + ab
(ax+b)(x+a)+bx+ab is the Second Term in the FOIL
Add both expressions together from First and Second Term
= ax^2 + a^2x + bx + ab
Step 3: Proof
(ax+b)(x+a) = ax^2 + a^2x + bx + ab
Identity is Found .
Trying with numbers now
(ax+b)(x+a) = ax^2 + a^2x + bx + ab

Answer:
Rank 1 - plane.
Rank 2- line.
Rank 3- point.
Step-by-step explanation:
Here, I have given the ranks based on what includes what.
Rank 1 is given to plane because infinite lines together makes a planes
and infinite points together makes a line.
so, Rank 1 includes both Rank 2 and Rank 3.
Now, Rank 2 is line because it consists of infinite number of points together
and is used to form a plane.
Rank 3 is point as it is the basic thing for any line or plane
See, it is simple, group of points make a line and group of lines make a plane.
visualize it this way,
When you zoom too in a plane, you see a line and when you zoom too in a line, you see a point.

seven friends have a similar cell phone plan
Four friends Ram, Mohan, Ajay and Sanjay are playing in a rectangular playground. Ram suggested his friends to get the position by keeping a stone in the middle of the park and he told the stone is the origin for their position. Now, they got the position of all four friends as (– 4, – 2), (– 3, – 5), (3, – 2) and (2, 3). Mohan claimed that their position will form a quadrilateral if taken in order. Ajay and Sanjay are now trying to calculate the area of the quadrilateral formed by their position if taken in order. How much area they calculated.
The area calculated by them is 21.
Step-by-step explanation:
The given points are (-4,-2),(-3,-5),(3,-2) and (2,3).
The area of the quadrilateral:
A= [tex]\frac{(x1 y2+x2y3+x3y4+x4y1)-(x2y1+x3y2+x4y3+x1y4) }{2}[/tex].
From the given points,
A=[tex]\frac{(20+6+9-4)-(6-1-4-12) }{2}[/tex]
A=[tex]\frac{(31)-(-11) }{2}[/tex]
A= [tex]\frac{42}{2}[/tex]
The area of the quadrilateral = 21.
Answer:
The are is 28
Step-by-step explanation:
Given:
Point 1: (– 4, – 2)
Point 2: (– 3, – 5)
Point 3: (3, – 2)
Point 4: (2, 3)
then, the coordinates of the first point are x1 = -4, y1 = -2; of the second point x2 = -3, y2 = -5; and so on.
We can compute the area of the quadrilateral with the shoelace formula as follows:
area = 1/2 * |x1*y2 + x2*y3 + x3*y4 + x4*y1 - x2*y1 - x3*y2 - x4*y3 - x1*y4 |
area = 1/2 * |(-4)*(-5) + (-3)*(-2) + 3*3 + 2*(-2) - (-3)*(-2) - 3*(-5) - 2*(-2) - (-4)*3 |
area = 1/2 * 56 = 28
Subtract these polynomials.

O A. - 2x2 + 2x+0
O B. 6x2 + 6x + 6
O C. 6x2+2x+ 0
O D.-2x2+68+6
Answer:
B. -2x2 + 6x + 6.
Step-by-step explanation:
(2x2 + 4x + 3) - (4x2 - 2x-3) Distribute negative over the parentheses:
= 2x2 + 4x + 3 - 4x2 + 2x + 3
= 2x2 - 4x2 + 4x + 2x + 3 + 3
= -2x2 + 6x + 6.
The correct answer to the polynomial subtraction question is D. -2x^2 + 6x + 6, obtained by changing the sign of each term in the second polynomial and then combining like terms.
Explanation:To subtract the given polynomials, we remove the parentheses and change the sign of each term in the second polynomial before combining like terms:
(2x2 + 4x + 3) - (4x2 - 2x - 3)
= 2x2 + 4x + 3 - 4x2 + 2x + 3
Now, combine like terms:
(2x2 - 4x2) + (4x + 2x) + (3 + 3)
= -2x2 + 6x + 6
The correct answer is D. -2x2 + 6x + 6.
THE GRINCH FOUND THE STRENGTH OF
2x6x3) ÷4+1 GRINCH'S PLUS TWO
Answer: 2x6x3=36 divided by 4=9+1=10.
The expression (2x6x3) ÷ 4 + 1 Grinch's plus two is solved using the order of operations, giving a result of 10 plus two Grinch's, symbolized as 10 + 2G.
Explanation:The question is a basic arithmetic problem that involves both multiplication and addition within parentheses, followed by division and then more addition.
The order of operations, often abbreviated as PEMDAS - which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right) - must be followed to solve the expression correctly.
Let's solve the expression step by step:
First, handle the expression within the parentheses: (2x6x3), which is multiplication. So, 2 times 6 equals 12, and 12 times 3 equals 36.Now, divide the result by 4: 36 ÷ 4 equals 9.Finally, add 1 to the result of the division: 9 + 1 equals 10.Add the last element of the expression, which is two Grinch's. Since we're not given a numerical value for a Grinch, let's symbolize it as 'G'. Therefore, if one Grinch is 'G', two Grinch's would be '2G'.The final answer is 10 plus two Grinch's, which we write as 10 + 2G.

Answer:
The separated values of x and y from the given equation is [tex]x=\frac{13-3y}{4}, y=1-\frac{4}{13}x[/tex]
Step-by-step explanation:
Given equation is [tex]4 x+3y=13[/tex]
Now to find the separated values of x and y with the given equation.
Now find the value of x and so we have to separate the value x from the given equation
[tex]4x+3y=13[/tex]
[tex]4x=13=3y[/tex]
[tex]x=\frac{13-3y}{4}[/tex]
Therfore [tex]x=\frac{13-3y}{4}[/tex]
Now find the value of y and so we have to separate the value y from the given equation
[tex]4x+13y=13[/tex]
[tex]13y=13-4x[/tex]
[tex]y=\frac{13-4x}{13}[/tex]
[tex]y=\frac{13}{13}-\frac{4x}{13}[/tex]
[tex]y=1-\frac{4}{13}[/tex]
Therefore [tex]y=1\frac{4}{13}x[/tex]
The separated values of x and y from the given equation is
[tex]x=\frac{13-3y}{4}, y=1-\frac{4}{13}x[/tex]
simplify (5^x+2-5^x)/5^x×4
Answer:
6
Step-by-step explanation:
The given expression is,
[tex]\frac{5^{x+2}-5^x }{5^x\times4}[/tex]
Now, we know that,
[tex]a^{m+n} = a^m . a^n[/tex]
Then,
[tex]5^{x+2}=5^x . 5^2[/tex]
So,
[tex]\frac{5^{x+2}-5^x}{5^x\times4}=\frac{5^x.5^2-5^x}{5^x\times4}[/tex]
Now, taking [tex]5^{x}[/tex] common from the numerator of the given expression, then
[tex]\frac{5^{x+2}-5^x}{5^x\times4}=\frac{5^x(5^2-1)}{5^x\times4}[/tex]
[tex]\implies\frac{5^{x+2}-5^x }{5^x\times4}=\frac{5^2-1}{4}[/tex]
[tex]\implies\frac{5^{x+2}-5^x}{5^x\times4}=\frac{5\times5-1}{4}=\frac{25-1}{4}[/tex]
[tex]\implies\frac{5^{x+2}-5^x}{5^x\times4}=\frac{24}{4}=6[/tex]
So, the simplified form of the given expression gives the result 6.
If 16 is added to 1/3 of a number the result is 3 times the number what is the number?
Answer: The number is 6
Step-by-step explanation:
Let the number be x,
1/3 of the number is the same as 1/3 of x , so from the first statement , we have
16 + [tex]\frac{1}{3}[/tex]x = 3x
Multiplying the equation through by 3 , we have
48 + x = 9x
48 = 9x - x
48 = 8x
divide through by 8
therefore :
x = 6
Therefore : the number is 6
If half the positive difference between 4.81 and 2.25 is multiplied by 0.32, what is the result?
The distance between 4.81 and 2.25 is 2.56.
Divide 2.56 by 2.
2.56 / 2 = 1.28.
Then multiply 0.38 by 1.28.
128 x 32 = 4096, then move the decimal 4 times to the left.
4096.
The decimal is behind the 6, you need to move the decimal in front of the 4.
Therefore, your result is 0.4096.
Paul brought and sold a computer .he wrote his business activity as followers cost price of computer =$1064 marked price of computer =$1399 discount on marked price =5%
Answer:
Profit = $265.04.
Selling price = $1329.05
Step-by-step explanation:
Paul brought a Computer at a cost price of $1064.
Now ,
The marked price of the computer is given as $1399.
Also,
He is giving a total discount of 5% on the marked price of the computer i.e., $1399.
So, The selling price of computer will become 95 percent of $ 1399 which equals $1329.05.
Thus Paul sold the computer at a profit of $1329.05 - $1064
= $265.04.
Answer:
A) selling price of computer is $1329.05
B) Profit is $265.05
C) Profit percentage = 24.9%
Step-by-step explanation:
Given as :
The cost price of computer = c.p = $1064
The marked price of computer = m.p = $1399
The marked percentage discount = d = 5%
Let The selling price of computer = s.p
Now, According to question
discount% = [tex]\dfrac{m.p - s.p}{m.p}[/tex]
Or, d% = [tex]\dfrac{m.p - s.p}{m.p}[/tex]
Or, 5% = [tex]\dfrac{1399 - s.p}{1399}[/tex]
Or, [tex]\dfrac{5}{100}[/tex] = 1 - [tex]\dfrac{s.p}{1399}[/tex]
Or, [tex]\dfrac{s.p}{1399}[/tex] = 1 - [tex]\dfrac{5}{100}[/tex]
Or, [tex]\dfrac{s.p}{1399}[/tex] = [tex]\dfrac{95}{100}[/tex]
∴ s.p = [tex]\dfrac{95}{100}[/tex] × 1399
Or, s.p = $1329.05
So,The selling price of computer = s.p = $1329.05
Now, Profit = selling price - cost price
or, p = s.p - c.p
Or, p = $1329.05 - $1064
∴ Profit = $265.05
Now, Profit % = [tex]\dfrac{\textrm profit}{c.p}[/tex]
Or, p% = [tex]\dfrac{\textrm 265.05}{1064}[/tex]
∴ p% = 0.249
i.e p = 0.249 × 100
So, profit percentage = 24.9%
Hence, A) selling price of computer is $1329.05
B) Profit is $265.05
C) Profit percentage = 24.9% Answer

What is an example of a complex number?
Complex numbers in mathematics. Complex numbers are numbers expressed in the form of a + ib. Here, a and b are real numbers, and "i" is an imaginary number called "iota". The value of i = (√-1). For example, 2 + 3i is a complex number, 2 is a real number (Re), and 3i is an imaginary number.
Complex numbers are numbers that consist of two parts: real and imaginary. Complex numbers are more complex mathematical components such as algebra. They can be applied to many aspects of real life, especially electronics and electromagnetism.

A rectangle has a length of 6 and a width of y + 4. Use the distributive property to write an expression to represent the area of the rectangle.
Answer:
[tex]\large\boxed{A=6y+24}[/tex]
Step-by-step explanation:
[tex]\text{The formula of an area of a rectangle:}\\\\A=l\times w\\\\l-\text{length}\\w-\text{width}\\\\\text{We have:}\\\\l=6,\ w=y+4\\\\\text{Substitute:}\\\\A=6\times(y+4)\\\\\text{use the distributive property}:\ a(b+c)=ab+ac\\\\A=(6)(y)+(6)(4)\\\\A=6y+24[/tex]
Final answer:
To find the expression that represents the area of the rectangle, use the distributive property. The expression is 6y + 24.
Explanation:
To find the expression that represents the area of the rectangle, we can use the distributive property. The area of a rectangle is given by the formula A = length imes width. So, for this rectangle, the length is 6 and the width is y + 4. To distribute the 6, we multiply it by both terms inside the parentheses: A = 6(y) + 6(4). This simplifies to A = 6y + 24, which is the expression that represents the area of the rectangle.

ASAP Need this answer, would appreciate it.
Answer:
Let's begin by explaining the following:
The magnitude of any number (a charge in this particular case) is the distance this number has from 0 on the number line.
Now, since according physics a distance can never be negative, the magnitude of a number will always be positive. This means the magnitude of these given charges will always be positive, no matter if they are negative, positive or neutral.
Having this clarified, let's answer:
Element A has a charge of +5 and its magnitude is +5
Element B has a charge of -3 and its magnitude is +3
Element C has a charge of 10 and its magnitude is +10
