4 0

Answer:

90 balls

Step-by-step explanation:

Set up proportion

36/x = 40/100

Cross multiply: 40x=3600

Solve for x

x=90

To check work:

40 percent of 90 would be 36

90(0.4)=36

$Find\ GCF(875;\ 1000)$

$875|5\\175|5\\.\ 35|5\\.\ \ 7|7\\.\ \ 1|\\875=\fbox5\times\fbox5\times\fbox5\times7\\\\1000|5\\.\ 200|5\\.\ \ 40|5\\.\ \ \ 8|2\\.\ \ \ 4|2\\.\ \ \ 2|2\\.\ \ \ 1|\\1000=\fbox5\times\fbox5\times\fbox5\times2\times2\times2$

$GCF(875;\ 1000)=\fbox5\times\fbox5\times\fbox5=125\\\\\frac{875}{1000}=\frac{875:125}{1000:125}=\frac{7}{2\times2\times2}=\boxed{\frac{7}{8}}$

A cone has a volume of 5 cubic inches. What is the volume of a cylinder that the cone fits exactly inside of?

Pie

Answer:

15 $in^{3}$

Step-by-step explanation:

Given:

Volume of Cone= 5 $inch ^{3}$

Solution:

Formula:

Volume of Cone = $\frac{1}{3} \pi r^{2} h$

Volume of Cylinder= $\pi r^{2} h$

$\therefore$ We can say that

Volume of Cone = $\frac{1}{3} \times$ Volume of Cylinder

$\therefore$ Volume of cylinder = 3 $\times$ Volume of Cone

Now Substituting given data we get

Volume of Cylinder= 3 $\times$ 5

Volume of Cylinder= 15 $in^3$
