Ali wants to wallpaper the back wall of his bedroom. The wall is in the shape of a rectangle. Its length is

Question

17
feet and its width is
13
feet. Suppose wallpaper costs
$5
for each square foot. How much will wallpaper cost for the wall?

Answer 1

The area of the wall is

17 feet x 13 feet = 221 square feet

So, the cost of wallpapering the wall is

221 square feet x $5/square foot = $1105

Answer 2

Mary wants to plant grass in her backyard. Her backyard is in the shape of a rectangle. Its length is
32
feet and its width is
21
feet. Suppose each pack of seed covers
12
square feet. How many packs of seed will she need to cover the backyard?

Answer 3

The area of the backyard is

32 feet x 21 feet = 672 square feet

To cover this area with seed, Mary will need

672 square feet / 12 square feet per pack = 56 packs of seed.

Answer 4

Yoko wants to paint the ceiling of her restaurant. The ceiling is in the shape of a square. Its side lengths are
39
feet. Suppose each can of paint will cover
169
square feet. How many cans will she need to paint the ceiling?

Answer 5

The area of the ceiling is

39 feet x 39 feet = 1521 square feet

To cover this area with paint, Yoko will need

1521 square feet / 169 square feet per can = 9 cans of paint (rounded up to the nearest whole number).

Therefore, she will need 9 cans of paint.

Answer 6

A coffee pot holds
3/14
quarts of coffee. How much is this in cups?
Write your answer as a whole number or a mixed number in simplest form.

Answer 7

We know that 1 quart is equal to 4 cups.

So, to convert 3/14 quarts to cups, we can set up a proportion:

3/14 quarts = x cups

1 quart = 4 cups

(3/14) / 1 = x / 4

Cross-multiplying:

3/14 * 4 = x

12/14 = x

Simplifying the fraction:

6/7 = x

Therefore, 3/14 quarts is equal to 6/7 cups in simplest form.

Answer 8

Heather cut 4 1/12 yards of fishing line from a new reel. How much is this in inches?
Write your answer as a whole number or a mixed number in simplest form.

Answer 9

We know that there are 3 feet in 1 yard, and 12 inches in 1 foot.

So, to convert from yards to inches, we can multiply by 3 (to get into feet) and then multiply by 12 (to get into inches):

4 1/12 yards = (4 x 3) + (1/12 x 3) yards = 12 + (1/4) yards

Now, we can convert to inches:

(12 + 1/4) yards = (12 x 36) + (1/4 x 36) inches = 432 + 9 inches

Simplifying:

432 + 9 = 441 inches

Therefore, 4 1/12 yards is equal to 441 inches in simplest form.

Answer 10

A fish tank has a volume of
6.9

ft3
.
Use the table of conversion facts to find out how many gallons of water it would take to completely fill the fish tank.
Round your answer to two decimal places.

Answer 11

One of the conversion facts we need to use is that 1 cubic foot is equal to 7.48 gallons.

So, to convert from cubic feet to gallons, we can multiply by 7.48:

6.9 ft3 * 7.48 gallons/ft3 = 51.732 gallons

Rounding to two decimal places:

51.73 gallons

Therefore, it would take approximately 51.73 gallons of water to completely fill the fish tank.
