Since we are dealing with volume, when one object is 4 times bigger than another, the difference in volume is 4^3 = 64.

6 cm sphere = 4/3 *PI * 6^3
6 cm sphere = 4/3 *PI * 216
6 cm sphere = 904.78 cc

24 cm sphere = 4/3 *PI * 24^3
24 cm sphere = 4/3 *PI * 13,824
24 cm sphere = 57,905.84 cc

Comparing the volumes: 57,905.84 / 904.78 = 64

Compare the slopes of the linear functions f(x) and g(x) and choose the answer that best describes them.

Tcecarenko [31]

Answer:

The slope of f(x) is equal to the slope of g(x).

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

step 1

Find the slope of the function f(x)

we have the points

(0,-1) and (3,1)

substitute in the formula

$m=\frac{1+1}{3-0}$

$m_1=\frac{2}{3}$

step 2

Find the slope of the function g(x)

take two points of the given table

(0,2) and (3,4)

substitute in the formula

$m=\frac{4-2}{3-0}$

$m_2=\frac{2}{3}$

step 3

Compare the slopes

$m_1=m_2$

therefore

The slope of f(x) is equal to the slope of g(x).

Find the measure of the arc indicated

exis [7]

Answer:

Step-by-step explanation:

Angle GPE is an inscribed angle. It intercepts arc GFE. The rule for inscribed angles and the arcs they intercept is that the angle is half the measure of the arc it intercepts. Angle P is 96, so that means that arc GFE is twice that. 2(96) = 192. We have arc FG as 92, so that means that arc FE is 192 - 92 which is 100 degrees. The third choice down.

Nour and Rana are shopping for a Christmas tree. They are deciding between

irga5000 [103]

Answer:

Sample Space:

1. (real, white)

2. (real, silver)

3. (real, gold)

4. (real, purple)

5. (fake, white)

6. (fake, silver)

7. (fake, gold)

8. (fake, purple)

Step-by-step explanation:

Nour and Rana each created a display to represent the sample space of randomly picking a type of tree and a color for the ornaments.

Whose display correctly represents the sample space?

We are not given their sample space but still you can compare the sample space you have with this one to find out whether it is correct or not.

There are 2 different types of Christmas trees

1. Real

2. Fake

There are 4 different types of colors for the ornaments

1. white

2. silver

3. gold

4. purple

The sample space is the set of all the possible outcomes of an experiment.

Then all of the possible outcomes are:

1. (real, white)

2. (real, silver)

3. (real, gold)

4. (real, purple)

5. (fake, white)

6. (fake, silver)

7. (fake, gold)

8. (fake, purple)

Therefore, there are total 8 possible outcomes.

Note: If your sample space matches with this one then it is correct otherwise it is not correct.
