Any sequence of transformations that include a “dilation” changes the overall size of the shape, so your answer would actually be “B” since it’s only being rotated and reflected. In other words, the location of the shape is the only thing being changed.

A hollow ball is made of rubber that is 1 centimeter thick. The ball has a radius of 5 centimeters at the outside surface.

serious [3.7K]

Given that the ball has a thickness of 1 cm and the radius at the outside is 5 cm, thus the radius from inside is 5 - 1 = 4cm.

The approximate volume of rubber used to make the ball is given by the volume of the ball at the outside surface minus the volume of the ball at the inside surface.

i.e.

 $Volume\ of\ rubber= \frac{4}{3} \pi\left(5^3-4^3\right) \\ \\ = 
\frac{4}{3} \pi(61)= \frac{244}{3} \pi\approx255.5\ cm^3$

The diagram shows a triangle.

Free_Kalibri [48]

Answer:

c=3

Step-by-step explanation:

Angle sum of a triangle is 180°

(19c+16)°+13c°+(17c+17)°=180°

collect the like terms i.e

19c+13c+17c+16+17=180°

49c°+33°=180°

49c°=180°-33°

49c°=147

dividing by 49 both sides

49c/49=147/49

c=3

What is the solution to this equation? 3x- x+8+5x-2=10

VashaNatasha [74]

3x -x + 8 + 5x - 2 = 10
3x - x + 5x = 10 -8 +2
7x = 4
x = 7/4

Which term does not belong with the other three?

Brrunno [24]

Answer:

The one that does not belong has a different number of dimensions.

Step-by-step explanation:

Given list consists of:

a line segment (AB)
a plane (CDE)
a line (FG)
a ray (HI)

Three of them have one dimension but the plane has two dimensions,

therefore the plane in the list does not belong with the other three.

So correct answer choice is:

The one that does not belong has a different number of dimensions.
