Answer:

12 and 136

Step-by-step explanation:

12 divided by 2 is 6, and 136 divided by 2 is equal to 68.

For the two numbers the quotient is between 136 divided by 6 will be 22 and 23.

We may examine the division and take into account the closest whole numbers to the quotient in order to get the two numbers that are the product of 136 divided by 6.

(Rounded to four decimal places) 136 divided by 6 equals 22.6667. 22 and 23 are the whole numbers that are most similar to this quotient.

We may then deduce that the value of the quotient of 136 divided by 6 is between 22 and 23. Accordingly, the outcome of the division of 136 by six will be a number more than or equal to 22 but less than 23. To put it another way, the quotient falls between [22, 23].

Step-by-step explanation:

the answer is d because the amount of speed changes the total amount of distance that he travels in time

Answer:

y = - 2x - 4

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

To calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 4, 4) and (x₂, y₂ ) = (2, - 8) ← 2 points on the line

m = [tex]\frac{-8-4}{2+4}[/tex] = [tex]\frac{-12}{6}[/tex] = - 2

the line crosses the y-axis at (0, - 4) → c = - 4

y = - 2x - 4 ← equation of line

Answer:

y= -2x-4

Step-by-step explanation:

Since, from the graph,we can see it is a straight line, therefore we apply the equation of the straight line that is:

y= mx+c where m is the slope and c is the intercept.

Since the points are(-4,4) and (2,8),

m= [tex]\frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }[/tex]

 = [tex]\frac{-8-4}{2+4}[/tex]

 =[tex]\frac{-12}{6}[/tex]

 = -2

Therefore, m= -2

Now,since c is the intercept and the line cuts y- axis at (0,-4), therefore

 c= -4

⇒y= mx +c

  y= -2x+ (-4)

 y= -2x_4

Answer:

5c + 30

Step-by-step explanation:

An easy way to create an equivalent expression is to simplify the equation given to you. In this case, distribute 5 to all terms within the parenthesis:

5(c) = 5c

5(6) = 30

5c + 30 is an answer choice.

Answer:

A motorcycle will complete the 540 mile trip in [tex]\frac{540}{48} = 11.25 hr[/tex]

And the car will complete it 2.25 hours less, i.e 11.25 -2,25 = 9 hours.

then,

Speed of the car is  [tex]\frac{540}{9} = 60 km/hr[/tex]

60t + 48t = 540

108t = 540

Divide both sides by 108 we get

t = 5

So, they will meet in 5 hours,

After 5 hours, the motorcycle will have traveled [tex]48 \times 5 = 240 miles[/tex]

and the car will have traveled = [tex]60 \times 5 = 300 miles[/tex]

Given is :

The distance between the cities Chicago and Toronto is = 540 miles

Speed of motorcycle = 48 mph

So, time taken by motorcycle to cover 540 miles = [tex]\frac{540}{48}=11.25[/tex] hours

Hence, the motorcycle will complete the 540 miles trip in 11.25 hours.

As given, the car takes 2.25 hours less to cover the same distance, so car takes [tex]11.25-2.25=9[/tex] hours

So,the speed of the car therefore is [tex]\frac{540}{9}=60[/tex] mph.

Let both the car and motorcycle meets is 't' time.

So, [tex]60t+48t=540[/tex]

[tex]108t=540[/tex]

t = 5

So, they will meet in 5 hours.

After 5 hours, the motorcycle will have traveled 48x5 = 240 miles

And the car will have traveled 60x5 = 300 miles.

Answer:

x - 6y = -9

Step-by-step explanation:

We are given two points (-3,1) and (3,2) on a line so we will use them to find the slope.

Slope ([tex]m[/tex]) = [tex]\frac{2-1}{3+3} =\frac{1}{6}[/tex]

The standard form of the equation is [tex]y=mx+c[/tex] so we will substitute the values of the coordinates of a point and slope (m) to find the y-intercept (c).

[tex]2=\frac{1}{6} +c\\\\c=\frac{3}{2}[/tex]

So the equation of the line which passes through the given points will be [tex]y=\frac{1}{6} x+\frac{3}{2}[/tex] which can be rearranged to write it as:

x - 6y = -9

Answer:

Option C.

Step-by-step explanation:

The standard form of a line is

[tex]Ax+By=C[/tex]

It a line passes through two points then the equation of line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

It is given that the line passes through the points (-3,1) and (3,2). So the equation of line is

[tex]y-(1)=\dfrac{2-1}{3-(-3)}(x-(-3))[/tex]

[tex]y-1=\dfrac{1}{6}(x+3)[/tex]

Multiply both sides by 6.

[tex]6(y-1)=x+3[/tex]

[tex]6y-6=x+3[/tex]

Subtract 6y and 3 from both sides.

[tex]6y-6-6y-3=x+3-6y-3[/tex]

[tex]-6-3=x-6y[/tex]

[tex]-9=x-6y[/tex]

Interchange both sides.

[tex]x-6y=-9[/tex]

Therefore, the correct option is C.

Boxes of sticky finger popsicles  are = $4.50

Supermarket is offering 30% coupon off.

We have to calculate the price with the coupon price of sticky finger popsicles will be given by

discounted price = original price - discount

                            = 4.50 - (30% of $4.50)

                           = 4.50 - (0.30 × 4.50)

Answer:

3. The mean will increase more than median, but both will increase.

Step-by-step explanation:

We have been given a dot plot. We are asked to find the true statement, if a new data point at 12 is added to our given dot plot.

Since we know that an large valued outlier affects mean more than median, so mean will increase more than median.

Let us check this using our given information. Our data set before adding 12 is:

1, 2, 2, 2, 3, 4, 4, 4, 5.

We can see that our data set has odd number (9) of data points, so median will be the value of 5th term, that is 3.

[tex]\text{Mean}=\frac{1+2+2+2+3+4+4+4+5}{9}[/tex]

[tex]\text{Mean}=\frac{27}{9}=3[/tex]

Therefore, mean of our data set is 3.

Upon adding a data point at 12, our new data set will be:

1, 2, 2, 2, 3, 4, 4, 4, 5, 12.

Now our data set has 10 terms, so median will be the average of 5th and 6th term.

[tex]\text{Median}=\frac{3+4}{2}[/tex]

[tex]\text{Median}=\frac{7}{2}=3.5[/tex]

Therefore, the median of new data set will be 3.5.

[tex]\text{Mean}=\frac{1+2+2+2+3+4+4+4+5+12}{10}[/tex]

[tex]\text{Mean}=\frac{39}{10}[/tex]

[tex]\text{Mean}=3.9[/tex]

Therefore, mean of new data set will be 3.9.

Upon looking at our given statements we can see that 3rd statement is true as mean and median both increased after adding 12 to our data set, but mean increased more that median. Mean and median before adding 12 was 3; but after adding 12 median became 3.5, while mean became 3.9 (which is greater than mean).

Answer:

The mean will increase more than the median, but both will increase.

Answer: In a right triangle, the sum of the squares of the two legs equals the square of the hypotenuse. Legs (a and b): the sides of the triangle adjacent to the right angle. They don't need to be the same length in order for this theorem to work.

If the sum of the squares of the legs of a triangle doesn’t equal the square of the hypotenuse, the triangle is not a RIGHT triangle.

We know that in a right angled triangle the Pythagorean Theorem hold true.

According to Pythagorean Theorem:

If the three sides lengths of a triangle are a,b and c respectively such that:

          [tex]c^2=a^2+b^2[/tex]

Then such a triangle is a right triangle with hypotenuse c and other two legs of triangle as a and b.

                            Hence, the answer is:

                       The triangle is not a right triangle.

The edge length of the original and new kennels were 3 and 4 feet respectively. Therefore, each edge length of the kennel increased by 1 foot.

Your question involves understanding the relationship between a cube's size, or its edge length, and its volume. The volume of a cube is calculated by cubing the edge length (Volume = Edge Length³). Therefore, the edge length of the original kennel is the cube root of 27, which is 3 feet. The edge length of the new kennel is the cube root of 64, which is 4 feet. So, each edge length of the kennel was increased by 1 foot (4-3).

Answer:

The formula for the volume of a sphere is:

Sphere Volume   =   4/3 • π • r^3

Sphere Volume   =   4/3 • π • 7^3

Sphere Volume   =   4/3 • π • 343

Sphere Volume   =   1,436.7550402417 cubic inches

Step-by-step explanation:

Final answer:

The volume of a hemisphere with a radius of 7 inches is calculated using the formula V = ½ (⅓πr³), resulting in a value of 571.1015 cubic inches, which rounds to 571.1 cubic inches.

Explanation:

To find the volume of a hemisphere with a radius of 7 inches, we use the formula for the volume of a sphere and then take half of that, since a hemisphere is just half of a sphere. The formula for the volume of a sphere is V = ⅓πr³. Since we need the volume of a hemisphere, our formula becomes V = ½ (⅓πr³). By substituting the given radius into the formula, we have:

V = ½ (⅓π(7 inches)³)

= ½ (⅓π(343 cubic inches))

= ½ (1142.203 cubic inches)

= 571.1015 cubic inches.

When we round this result to the nearest tenth, we get 571.1 cubic inches. Hence, the volume of the hemisphere is approximately 571.1 cubic inches.

Answer: 2 solutions.

The given equation breaks down into these two equations

3x+12 = 18 and 3x+12 = -18

Basically 3x+12 equal to plus 18 and minus 18. This is due to the fact that something like |x| = 7 means x = 7 or x = -7, ie those x values are exactly seven units away from zero on the number line.

If you want to solve each equation, then

3x+12 = 18

3x = 18-12

3x = 6

x = 6/3

x = 2 is one solution

and

3x+12 = -18

3x = -18-12

3x = -30

x = -30/3

x = -10 is the other solution

Answer:

y = -3x + 2; y = ⅓x -14/3

Step-by-step explanation:

Step 1. Find the equation of the parallel line

Original line: y = -3x+ 7

Parallel line: slope = m₁ = -3

The line passes through (2, -4).

 y = m₁x + b      Insert the values

-4 = (-3)×2 + b

-4 = -6 + b        Add 6 to each side

b = 2

y = -3x + 2

===============

Step 2. Find the slope (m₂) of the perpendicular line

m₂ = -1/m₁     Substitute the value of m₁

m₂ = -1/(-3)

m₂ = ⅓

====================

Step 3. Find the equation for the perpendicular line

y = mx + b

y = ⅓x + b

The line passes through (2, -4).  

-4 = ⅓(2) + b      Substitute the values

-4 = ⅔ + b         Subtract ⅔ from each side

-4 - ⅔ = b

 b = -14/3

y = ⅓x - 14/3

In the image, below  the graph of your original equation is the red line.

The green line passing through (2, -4) is the parallel line.

The purple line passing through (2, -4) is the perpendicular to both lines.
