First, you need to find what percent of students would vote for Suzy out of the original 200. To do so, divide 25/200. You get 12.5% (or 0.125). Then, multiply that percent by the 1,000 students. You will get 125 students. Hope this helps!

Or another way is to do 1000 divided by 200= 5 then you do 5 times 25 equals 125

These cones are similar. find the volume of the smaller cone. round to the nearest tenth.
Kamila [148]

Answer:

Volume of the smaller cone = 8.34 cm³

Step-by-step explanation:

"If two figures are similar, their dimensions will be proportional.

Following this rule,

Ratio of the dimensions of two cones = \frac{\text{Radius of the large cone}}{\text{Radius of the small cone}}

                                                               = \frac{r_2}{r_1}

                                                               = \frac{5}{2}

                                                               = 2.5

Similarly, "ratio of the volumes of two similar figures is cube of the dimensional ratio".

Ratio of the volumes = (ratio of the dimensions)³

\frac{V_1}{V_2}=(2.5)^3

\frac{131}{V_2}=15.625

V_2=\frac{131}{15.625}

    = 8.384 cm³  

    ≈ 8.4 cm³

Therefore, volume of the smaller cone is 8.4 cm³.

egoroff_w [7]

Answer:

900

Step-by-step explanation:

The figure is a triangular prism

The equation would be V = A * H / 3

V being the volume

A being the area of the pyramids base

H being the height front he base to the top  (20)

Base area is 135 (A)

135 * 20 = 2700

2700 divided by 3 = 900

900 is your answer
