Bill bought a piece of cloth that was 30 inches wide and 12 feet long. if the cloth cost $6 per square yard, then how much did i
Oksanka [162]
Let's figure out how many square yards you have by first converting all of the measurements into yards:
30 inches x( 1 yard/36 inches) = 30/36 yd = 5/6 yd
12 feet x (1 yard/3 feet) = 4 yards.

Now multiply length x width:
5/6 x 4 = 20/6 or 3 1/3 square yards.

Finally, multiply unit price by square yards:
$6 per sq yd x 3 1/3 sq yd = $20 cost

Use unit multipliers to convert 123 pounds per mile to ounces per centimeter. There are 5,280 feet in 1 mile. There are 16 ounce
gregori [183]
A unit multiplier is a conversion factor of value 1 that we can use to convert quantities.
We want to convert 123 pounds per mile to ounces per centimeter. 
First, we are going to express the quantity to convert as a fraction:
123 pounds per mile=123 \frac{pounds}{mile}

Next, we are going to find our multipliers:
- We know for our problem that there are 5,280 feet in 1 mile, so our first multiplier will be: \frac{1mile}{5280ft}
- We also know that there are 16 ounces in 1 pound, so our second multiplier will be: \frac{16ounces}{1pound}
- We know that there are 12 inches in 1 foot, so our third multiplier will be: \frac{1ft}{12in}
- We know that t<span>here are approximately 2.54 cm in 1 inch, so our fourth multiplier will be: </span>\frac{1in}{2.54cm}

Now we can put all our multipliers together:
123 \frac{pounds}{mile} * \frac{1mile}{5280ft}*\frac{16ounces}{1pound}* \frac{1ft}{12in}*\frac{1in}{2.54cm}=0.01 \frac{ounces}{cm}

We can conclude that the answer is 0.01

27. 1

28. 49

29. 169

30. 256

Step-by-step explanation:

26. (b/2)² = (-8/2)² = 16

27. (b/2)² = (-2/2)² = 1

28. (b/2)² = (-14/2)² = 49

29. (b/2)² = (26/2)² = 169

30. (b/2)² = (-32/2)² = 256
