Okay, so if it leaks out a pint every hour, and a gallon is 8 pints, it will take 8 hours to leak out 1 gallon. Since there are 24 hours in a day, it would leak out 3 gallons every day. Now, assuming the month we are talking about is 31 days, then we multiply 31 with 3, giving us 93 gallons in a month. 
Do you need help with the third too?

A toy rocket launched into the air has a height ( h feet) at given time ( t seconds) as h= -16^2+160t until it hits the ground.
Gennadij [26K]

Answer:

t = \frac{53}{32}

Step-by-step explanation:

h=\:-16^2+160t

9=\:-16^2+160t      substitute

-16^2+160t=9

-256+160t=9

-256+160t+256=9+256

160t=265

\frac{160t}{160}=\frac{265}{160}

t=\frac{53}{32}

At  \frac{53}{32}  seconds it is at a height of 9 ft.

Find the missing number in this proportion.<br><br> 7 2<br> = <br> 4
borishaifa [10]

Answer:

x = 14

Step-by-step explanation:

I don't know which one you are supposed to solve it by so I will do both.

Solution by Cross Multiplication

For the equation

7x=24

The cross product is

7×4=x×2

Solving for x

x=7×42

and reducing

x=14

Solution by Proportion

Since the equation is an equality

If

7 ÷ 2 = 3.5

Then it is true that

x ÷ 4 = 3.5

Solving for x

x = 4 × 3.5

x = 14
