Part B: 120 minutes.

Step-by-step explanation:

Part A:

Given:

Amount of fabric required for 1 cape is 1 yard.

Total amount of fabric bought by Zoe's mom are 10 yards.

Using unitary method,

∵Number of capes made from 1 yard fabric = 1

∴ Number of capes made from 10 yard fabric = $10\times 1=10$

Part B:

Given:

Time taken to make 1 cape is 12 minutes.

Using unitary method,

∵Time taken to make 1 cape = 12 minutes.

∴ Time taken to make 10 capes = $12\times 10=120$ minutes.

The length of a park is 2/5 miles and the area is 9/10 square miles. What is the width of the park?

OverLord2011 [107]

To find the width, divide the area by the length.

Width = 9/10 / 2/5

When dividing fractions flip the second one over and multiply:

Width = 9/10 x 5/2 = (9 x5) / (10 x 2) = 45/20 = 2 and 1/4 miles.

A tank sprung a leak in the water level started drop from 24.8 m at a rate of 2 m/h. Right and solve an equation to determine ho

malfutka [58]

Answer:

8 hours.

Step-by-step explanation:

The initial water level is 24.8 meters, and the rate of water level drop is 2 meters/ hour, that means after $t$ hours the water level $L$ will be

$L =24.8-2t$

Now we want water level to be 8.8 meters, I.e $L=8.8m$ , therefore, we have:

$L=8.8=24.8-2t$

we solve the equation for $t$ :

$8.8=24.8-2t\\8.8+2t=24.8\\2t=24.8-8.8\\2t=16\\\\\boxed{t=8}$

it will take 8 hours for the water level to drop to 8.8 meters.
