A proofreader can read 40 pages in one hour. How many pages can this proofreader read in 90 minutes?

2 answers:

One hour is equal to 60 minutes. That gives you a fraction of 40 pages/60 minutes.

You don't know how many pages they can read in 90 minutes, so you would do
x pages/90 minutes.

The equation you would set up is 40/60 = x/90.

After cross multiplying you get 60x = 3600. Divide both sides by 60 to isloate the x, and you end up with x = 60.

A proofreader who can read 40 pages in one hour (60 minutes) can reading 60 pages in 90 minutes.

HELP .-. A painter bought 16 gallons of paint, just to cover two rooms. One room is twice the size of the other room and require

givi [52]

The total number of gallons of paint needed for the big room is 3x and the number of gallons of paint needed for the small room is 2y.
3x + 2y = 16
Given the sizes of the room, the relation should be that,
x = 2y
Solving the equation,
3(2y) + 2y = 16
y = 2
Therefore x is equal to 4 gallons.
With the condition that only the bigger room is painted, the number of gallons of paint used should be 12 gallons and what is left should be 4 gallons.

A fruit bowl contains 2 bananas, 5 oranges, and 4 apples in the simplest form, what is the ratio of apples to bananas in the fru

prisoha [69]

Answer:

Ratio of apple to banana is 2:1

Step-by-step explanation:

To find ratio of x type of one thing and y type of other thing we divide

x by y and ratio is written as

ratio = x:y

_________________________________

Number of banana = 2

Number of apples = 4

Ratio of apple to banana = Number of apples :Number of banana

Ratio of apple to banana = 4:2

since 4 is divisible by 2 , to get the ratio in simplest form

we divide both numerator and denominator by 2

Ratio of apple to banana = 4/2:2 /2 = 2:1

Thus,

Ratio of apple to banana is 2:1
