Answer:
1 69/145 cups
Step-by-step explanation:
We can use ratio's to solve this problem. We will put water over time
214 cups x cups
--------------- = --------------
145 hours 1 hours
Using cross products
214 *1 =145 x
Divide both sides by 125
214/145 = 145x/145
214/145 = x
145 goes into 215 1 time with 69 left over
1 69/145
Answer:
3.
Step-by-step explanation:
Let's break it down.
Sparkles used 12 balloons total to make 4 balloon animals. Divide 12 by 4, and you will get 3.
What I did for part 2 of the equation, is I multiplied 4 and 5 by 3 to ensure the variable matched my calculations. 4x3 is 12, and 5x3 is 15. add 12 and 15, and you will get 27 total balloons.

Answer:
A = 24t² + 2t
Step-by-step explanation:
The shaded area (A) is calculated as
A = area of outer square - area of rectangle
= (5t)² - t(t - 2)
= 25t² - t² + 2t
= 24t² + 2t
