Why is it important to convert rates to the same units before comparing them

Answers

Answer 1

Answer: because, if you have different rates and convert them, they won't be correct. its easier to convert them and then compare. (if that makes sense?)

A cone has a volume of 24 cubic inches. What is the volume of a cylinder that the cone fits exactly inside of? 8 in3
24 in3
48 in3
72 in3

Answers

Answer:

72 cubic inches

Step-by-step explanation:

Volume of cone = $(1)/(3)\pi r^(2) h$ --1

Volume of cylinder = $\pi r^(2) h$ --2

We are given that a cylinder should fit exactly inside the cone

On comparing 1 and 2 we can see:

$\text{Volume of cone}= (1)/(3) \text{Volume of cylinder}$

Since we are given the volume of cone is 24 cubic inches .

So, $24= (1)/(3) \text{Volume of cylinder}$

$24 * 3= \text{Volume of cylinder}$

$72= \text{Volume of cylinder}$

Hence the volume of cylinder is 72 cubic inches

PLS HELP FIRST CORRECT ANSWER GETS BRAINLIEST !! A pile of tailings from a gold dredge is in the shape of a cone. The diameter of the base is 34 feet and the height is 16 feet. Approximately, how many cubic feet of gravel is in the pile? Use π = 3.14.A. 14,527 ft³
B. 285 ft³
C. 4,840 ft³
D. 6,032 ft³

Answers

The volume of the cone is 4840 cubic ft if the diameter of the base is 34 feet and the height is 16 feet option (C) is correct.

What is a cone?

It is defined as a three-dimensional shape in which the base is a circular shape and the diameter of the circle decreases as we move from the circular base to the vertex.

$\rm V=\pi r^2(h)/(3)$

Volume can be defined as a three-dimensional space enclosed by an object or thing.

It is given that:

A pile of tailings from a gold dredge is in the shape of a cone.

The diameter of the base is 34 feet and the height is 16 feet.

As we know,

The volume of the cone is given by:

$\rm V=\pi r^2(h)/(3)$

r = 34/2 = 17 ft

h = 16 feet

Plug the above values in the formula:

$\rm V=\pi (17)^2(16)/(3)$

After solving:

V = 1541.33π cubic feet

Take π = 3.14

V = 1541.33(3.14) cubic feet

V = 4839.78 ≈ 4840 cubic ft

Thus, the volume of the cone is 4840 cubic ft if the diameter of the base is 34 feet and the height is 16 feet option (C) is correct.

Answer:

C: $V=4840 (2 s.f.)$

Step-by-step explanation:

The formula for the volume of a cone is:

$V= (1)/(3) \pi r^2h$

Therefore,

$V=(1)/(3)* 3.14*((34)/(2))^2* 16\n\nV=4840 (2 s.f.)$

Melissa is making clothes for her dolls. She has 7/8 yard of fabric. Each doll shirt requires 2/7 of a yard of fabric. How many whole shirts can she make for her dolls? a. 2 b. 3 c. 4 d. 5

Answers

Step-by-step explanation:

Since you have 7/8 of a yard of fabric and 2/7 needed you would take the 7/8 and divide by 2/7

7/8 / 2/7

Since these are fractions you would take the second number and turn in into its reciprocal

7/8 x 7/2

49/16

3 1/16

You can make 3 full shirts
