Mya is doing a 45-minute cardio workout. She has completed 4 5 of the workout. In how many minutes will her workout be done?

Answer:

The amount of wool required for a sweater was 400 grams.

A hat needed 80 grams of wool.

A scarf required 75 grams of wool.

Step-by-step explanation:

Let

x ------> grams of wool necessary for a sweater

y -----> grams of wool necessary for a hat

z -----> grams of wool necessary for a scarf

From the information given

x+y+z=555 -----> equation A

y=x/5 ----> x=5y -----> equation B

y=z+5 ---> z=y-5 ----> equation C

By substituting equations B and C into equation A, we can solve for y:

(5y)+y+(y-5)=555

7y=560

y=80 grams

Now, find x

x=5(80)=400 grams

Next, determine z

z=80-5=75 grams

In conclusion,

400 grams of wool was required for the sweater,

the hat needed 80 grams of wool, and

the scarf required 75 grams of wool.

Answer:

16 cubic feet per hour

Step-by-step explanation:

This involves a straightforward conversion from inches to feet.

Step 1: Establish the conversion scale

---> the volume of water in 1 minute is 462 cubic inches

--->1 cubic foot = 1728 cubic inches

--->1 hour consists of 60 minutes,

Step 2: Determine the volume in feet per hour

Volume of water in one hour =  0.0347 x 462

---> the amount of water in 1 hour =  = 16.0314 cubic feet

---> Rounded to--> 16 cubic feet

Thus, 462 cubic inches per minute equates to 16 cubic feet of water on an hourly basis
