a ratio is how many X there are per Y. for example, a fraction is a ratio: 10/5 = 2 because there are 2 fives in a ten. but usually a ratio is written as x:y.

so to find these ratios, first we need to find the number of girls. 30 students-16 boys = 14 girls.

the ratio of girls to boys is 14:16 because there are 14 girls to every 16 boys. we simplify this to 7:8.

the ratio of girls to all students is 14:30. we simplify this to 7:15.

the ratio of boys to girls is 16:14, which simplifies to 8:7.

the ratio of boys to all students is 16:30, which simplifies to 8:15.

A french fry stand at the fair serves their fries in paper cones. The cones have a radius of 22 inches and a height of 66 inches
icang [17]

Answer:

The height of the new cones will be 16.5 inches.

Step-by-step explanation:

We know that,

The volume of a cone is,

V=\frac{1}{3}\pi r^2 h

Where, r is the radius of the cone,

h is the height of the cone,

In the original cone,

r = 22 inches,

h = 66 inches,

Thus, the volume would be,

V_1=\frac{1}{3}\pi (22)^2(66)

Also, for the new cone,

r = 44 inches,

Let H be the height,

So, the volume of the new cone would be,

V_2=\frac{1}{3}\pi (44)^2(H)

According to the question,

V_2=V_1

\implies \frac{1}{3}\pi (44)^2(H)=\frac{1}{3}\pi (22)^2(66)

\implies H=\frac{22^2(66)}{44^2}=(\frac{22}{44})^2\times 66 = \frac{66}{4}=16.5

Hence, the height of the new cones will be 16.5 inches.
