At his last track meet, Eli ran the 400-meter dash in 54 seconds. His friend Kimberly bet him that he couldn't run a whole kilometer at that pace, but Eli is determined to prove her wrong. How many minutes would he have to run at this pace to win the bet?
Write your answer as a whole number, decimal, or simplified fraction. Do not round.
Answer:
Eli has to run for 2.25 minutes at this pace to win the bet.
Step-by-step explanation:
At his last track meet, Eli ran the 400-meter dash in 54 seconds.
So, the speed of Eli's run is [tex]\frac{400}{54} \times 60 = 444.44[/tex] meters per minute.
Now, if Eli is determined to run a whole kilometer with the same speed, then it will take Eli to run 1 kilometer within [tex]\frac{1000}{444.44} = 2.25[/tex] minutes.
Hence, Eli has to run for 2.25 minutes at this pace to win the bet. (Answer)

6/x = 42/36
42x= 216
x= 5.14
What is X in this equation?
3x+55=9x-5
Please Explain.
Answer:
x = 10
Step-by-step explanation:
3x + 55 = 9x - 5 (add 5 to both sides)
3x + 55 + 5 = 9x - 5 + 5
3x + 60 = 9x (subtract 3x from both sides)
60 = 9x - 3x
60 = 6x (rearrange)
6x = 60 (divide both sides by 6)
x = 60/6
x = 10

The lid of a jewelry box is in the shape of a triangular prism. The lid has a height of 10 inches. The triangular base of the lid has a base of 6 1/2 inches and a height of 3 1/2 inches. What is the volume of the lid to the nearest tenth?
The volume of the lid is approximately 113.8 cubic inches.
Explanation:The volume of the lid can be found by multiplying the area of the triangular base by the height of the lid. The area of a triangle can be found by using the formula: Area = (base x height) / 2. In this case, the base is 6 1/2 inches and the height is 3 1/2 inches. Plugging these values into the formula, we get: Area = (6.5 x 3.5) / 2 = 11.375 square inches. Now, to find the volume of the lid, we multiply the area by the height: Volume = 11.375 x 10 = 113.75 cubic inches. Rounding to the nearest tenth, the volume of the lid is 113.8 cubic inches.
The volume of the lid is 113.8 cubic inches.
To determine the volume of the lid of the jewelry box, we need to use the formula for the volume of a triangular prism, which is V = (1/2 * base * height of triangular base) * height of the prism.
First, calculate the area of the triangular base:
Base of the triangular base: 6.5 inchesHeight of the triangular base: 3.5 inchesArea = 1/2 * 6.5 inches * 3.5 inches = 11.375 square inchesNext, multiply the area of the triangular base by the height of the prism:
Height of the prism: 10 inchesVolume = 11.375 square inches * 10 inches = 113.75 cubic inchesTherefore, the volume of the lid to the nearest tenth is 113.8 cubic inches.
The endpoint of a diameter of a circle are (-4,2) and (12,10). What is the y-coordinate for the center of the circle
Answer:
6
Step-by-step explanation:
The center of the circle is the midpoint of the diameter. The midpoint can be found by averaging the coordinates of the end points:
((-4, 2) +(12, 10))/2 = ((-4+12)/2, (2+10)/2) = (4, 6)
The y-coordinate of the center is 6.
The center of the circle has a y-coordinate of 6, determined by averaging the y-coordinates (2+10)/2 of the diameter's endpoints (-4,2) and (12,10).
Explanation:The y-coordinate for the center of a circle can be determined by finding the midpoint of the y-coordinates of the diameter's endpoints. Given the endpoints (-4,2) and (12,10), the midpoint can be found by averaging the y-coordinates: (2 + 10) / 2 = 12 / 2 = 6. Therefore, the y-coordinate of the center of the circle is 6.

A total of 492 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was three times the number of adult tickets sold. How many adult tickets were sold?
Answer:
164 adult tickets
Step-by-step explanation:
164×3 = 492 tickets
Really hope this helped! :)
Final answer:
A total of 123 adult tickets were sold for the school play, with the total number of tickets sold being 492 and student tickets being three times the number of adult tickets.
Explanation:
To solve the problem of how many adult tickets were sold at the school play when a total of 492 tickets were sold and the number of student tickets was three times the number of adult tickets, we set up a system of equations. Let A be the number of adult tickets and S be the number of student tickets sold.
Steps to solve this question:
The total number of tickets sold was 492: A + S = 492
The number of student tickets was three times the number of adult tickets: S = 3A
We can substitute the second equation into the first to find the number of adult tickets:
A + 3A = 492
4A = 492
A = 492 / 4
A = 123
Therefore, 123 adult tickets were sold for the school play.

Step-by-step explanation:
We need to analyze the surface
Look at the L shape, it has a mirror image at the back, which is symmetrical to the front side
Then,
area of rectangle = length × breadth
The L shape can be divided into two plane shape
1. A rectangle of length 10in and breadth 6in,
Then, A=l×b=10×6 = 60in²
2. To a square of side a=4in
Then, A=s²=4²=16in²
Then, the total area of one side of the L shape is
A=60+16=76in²
Also, the total area of the two L shape is =2×76
A=152in²
Then, let look at the back side of the solid and the front side, they are also symmetrical.
It forms a rectangle of length 10in and breadth 6in
Then, A= l×b=10×6=60in²
Area of the two sides is =60×2
A=120in²
The total are of the front and back side is 120in²
A=120in²
Let take a look at the top and bottom, they are also symmetrical and has a dimension of length 10in and breadth 6in
Then, A=l×b=10×6=60in²
So, total area =2×60 =120in²
The total area of the shape is the total area of top+ total are of the sides + total area of the L shape
Total area=152+120+120=392in²
A(total)=392in²
Then, the total area of the solid shape is 392in²
The first option is correct

Step 2
Step 3
= 480 – 15
Step 4
465
Where is the error
Answer:
The right answer is, -420
Step-by-step explanation:
Because we use common factor:
60 (x - 15)
We multiply for each term:
60 (x) - 60 (15)
60 (8) - 60 (15)
We solve:
480 - 900 = -420
1. y = 6x
2x + 3y = -20
Step-by-step explanation:
[tex]y = 6x[/tex]
[tex]2x + 3y = -20[/tex]
To solve this system of equations, let's multiply the first equation by [tex]-3[/tex] to get a [tex]3y[/tex] term in each equation:
[tex]-3y = -18x[/tex]
Now, let's add the two equations together:
[tex](2x + 3y) + (-3y) = -20 + (-18x)[/tex]
[tex]2x = -20 - 18x[/tex]
[tex]20x = -20[/tex]
[tex]x = -1[/tex]
Now, we can plug in this value of [tex]x[/tex] into either equation to solve for [tex]y[/tex]:
[tex]y = 6x[/tex]
[tex]y = 6(-1)[/tex]
[tex]y = -6[/tex]
or
[tex]2x + 3y = -20[/tex]
[tex]2(-1) + 3y = -20[/tex]
[tex]-2 + 3y = -20[/tex]
[tex]3y = -18[/tex]
[tex]y = -6[/tex]
Therefore, the solution to this system of equations is [tex](-1, -6)[/tex].
Answer:
x = -1
y = -6
Step-by-step explanation:
y = 6x
2x + 3y = -20
Substitute the first expression into the second one
We have
2x + 3y = -20
2x + 3(6x) = -20
2x + 18x = -20
20x = -20
Divide both sides by 20 to isolate x
20x/20 = -20/20
x = -1
Remember the first expression
y = 6x
Therefore
y = 6(-1)
y = 6 x -1
y = -6
Check
2(-1) + 3(-6) = -20
-2 + -18 = -20
-2 - 18 = -20
-20 = -20
So our answer is correct

If f(x) = -3x – 9 and g(x) = (x+7,
what is (fºg)(-6)?
Helppp
Answer:
-12
Step-by-step explanation:
we know that
(fºg)(x)=f(g(x))
To find out the composite function f(g(x)) substitute the variable x in the function f(x) by the function g(x)
we have
[tex]f(x)=-3x-9[/tex]
[tex]g(x)=x+7[/tex]
so
[tex]f(g(x))=-3(x+7)-9[/tex]
For x=-6
substitute
[tex]f(g(-6))=-3(-6+7)-9[/tex]
[tex]f(g(-6))=-3(1)-9[/tex]
[tex]f(g(-6))=-12[/tex]

3200 dollars is placed in an account with an annual interest rate of 8.25%. To the nearest tenth of a year, how long will it take for the account value to reach 9600 dollars?
Answer:13.9
Step-by-step explanation:
Using the compound interest formula, it will take approximately 14.9 years for an account with a $3,200 initial deposit and an 8.25% annual interest rate to grow to $9,600.
Explanation:To find out how long it will take for an account with an initial value of $3,200 and an annual interest rate of 8.25% to grow to $9,600, we can use the future value formula for compound interest:
The formula is FV = PV (1 + r)^n, where:
FV is the future value of the money after n years,PV is the present value or initial amount (which is $3,200),r is the annual interest rate (which is 0.0825), andn is the number of years.To find n when FV is $9,600, we rearrange our formula to solve for n:
n = log(FV / PV) / log(1 + r)
Now, plug in the values:
n = log(9600 / 3200) / log(1 + 0.0825)
n = log(3) / log(1.0825)
n ≈ 14.9 years
So, it will take approximately 14.9 years for the account value to reach $9,600.

If you were calculating the volume of a cube that has a side length of 8 inches, how would you write the calculations in exponential form? What are 2 more ways to read the exponent verbally.
Answer: 8^3, Eight to the third power, Eight times eight times eight.
To calculate the volume of a cube with a side length of 8 inches, you write the calculation in exponential form as V = 8^3, which is read as '8 cubed' or '8 to the third power', resulting in a volume of 512 cubic inches.
Explanation:To calculate the volume of a cube using a side length of 8 inches, you can write the calculation in exponential form as V = 8^3. This represents the volume (V) as the length of a side of the cube (8 inches) raised to the power of 3. In exponential form, 8^3 is 8 cubed or 8 to the third power, both of which mean 8 multiplied by itself twice more (8 x 8 x 8).
Therefore, the volume of the cube would be 512 cubic inches because 8 x 8 x 8 equals 512.
find the equation of the tangent to the curve at x=3 for parametric equations
x = t + 1/t
y = t^2 + 1/(t^2) when t is greater than 0
Answer:
y = 6x − 11
Step-by-step explanation:
x = t + (1/t), y = t² + (1/t²)
If we square x:
x² = t² + 2 + (1/t²)
x² = y + 2
When x = 3, y = 7.
Taking derivative with respect to time:
2x = dy/dx
dy/dx = 6
So the equation of the tangent line is:
y − 7 = 6 (x − 3)
y − 7 = 6x − 18
y = 6x − 11
the equation of a line β is 2x-3y=6
find the gradient of β
Answer:
2/3
Step-by-step explanation:
Rewrite the equation into the form of y=mx+c
m is the gradient of the line.
2x-3y=6
3y= 2x-6 (bring y terms to one side, the rest to the other)
y= 2/3x -2 (÷3 throughout)
Thus the gradient is 2/3.

How you find co-terminal is by adding or subtracting 360 degrees to the value you are given.
If it is a positive number like #18. all you do is subtract 510 - 360 = 150 until you get to a value between 0 degrees and 360 degrees.
The same thing applies to negative numbers. Like #21. You will add 360 + (-660) until you get to a number between 0 degrees and 360 degrees.
-660 + 360 = -300 (this is not a value in between 0 and 360 so we must add 360 again)
-300 + 360 = 60 (this is a value in between 0 and 360) (this is the co-terminal angle)
That is the idea of finding co-terminal angles.
