Which of the following inequalities are correct?
Natali5045456 [20]

Answer:

A and B

Step-by-step explanation:

- 3/5 is less than -1/5 because it is farther away from 0 on a number line (also, when it comes to figure out which inequality is true with negative number, the smaller one is going to be greater because it is closer to 0 on a number line)

3/5 is greater than 1/5 because they are both positive and 3/5 is the bigger number

-1/5 is not less than -3/5 because if A is true, than this cannot be true because it is saying the exact opposite.

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.
