Its more than the exact answer because you would round 342 to 340 because 350 is an overestimate. I decided because when your rounding you only round up if the ones place value is larger than 5 but in this case its not.

Answer:

the answer is c) 182.25

Step-by-step explanation:

The information provided gives you a scale that will ultimately allow you to determine the height of the larger cylinder.

Since it tells us the two are similar, we can use the scale to solve for the second height.

Set up your math like this:

\frac{16}{h}=\frac{64}{729}

h represents the height you are trying to find.

using a common multiple, you can solve for h.

16 times 4 is 64. so 729 divided by 4 is 182.25

4m + 2(8) = 5(8) solve for m
ollegr [7]

Answer:

m = 6

Step-by-step explanation:

4m + 2(8) = 5(8) (Given)

4m + 16 = 40 (Simplify)

4m + 16 - 16 = 40 - 16 (Subtraction Property of Equality)

4m = 24 (Simplify)

\frac{4m}{4} = \frac{24}{4} (Division Property of Equality)

m = 6 (Simplify)

A rectangular bathroom mirror has a perimeter of 22 feet. Its area is 18 square feet. What are the dimensions of the mirror?
ad-work [718]

Answer:

The dimensions of the mirror is 9 feet and 2 feet

Step-by-step explanation:

Keep in mind that the area and perimeter of a rectangle is:

Area - length x width

Perimeter - 2 (l + w)

List the factors of 18 (the area of the mirror):

1, 2, 3, 6, 9, 18

POSSIBLE DIMENSIONS OF MIRROR:

1 ft and 18 ft

Area = 18 ft^2

Perimeter = 38 feet

2 ft and 9 ft

Area = 18 ft^2

Perimeter = 22 feet

3 ft and 6 ft

Perimeter = 18 feet

The rectangle with dimensions 2 feet and 9 feet corresponds with the area and perimeter of the mirror mentioned. So those are the correct dimensions.

Hope these helps!
