If gas costs $4.55 per gallon how many whole gallons of gas could you buy with $12.00?

Answers

answer: 2
4.55•2=9.10
4.55•3=13.65

The amount of gallons of gas that can be bought with $12 is 2.64 gallons.

What is a unit rate?

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

Cost of gas per gallon = $4.55

This can be written as,

1 gallon = 4.55

Multiply 12/4.55 on both sides.

12/4.55 gallons = 12/4.55 x 4.55

2.64 gallons = 12

This means,

2.64 gallons for $12.

Thus,

2.64 gallons can be bought for $12.

Machine A and machine B both make car parts.
Machine A makes 7 parts every 10 minutes.
Machine B makes 16 parts every 15 minutes.
On Monday
machine A makes parts for 12 hours
machine B makes parts for 10 hours
Work out the total number of parts made by the two machines on Monday.

Answers

Answer:  1144

Step-by-step explanation:

Given: Machine A makes 7 parts every 10 minutes.

i.e. it makes [tex]\dfrac{7}{10}[/tex] parts in 1 minute.

Machine B makes 16 parts every 15 minutes.

i.e. it makes [tex]\dfrac{16}{15}[/tex] parts in 1 minute.

On Monday,

machine A makes parts for 12 hours(720 minutes).    [1 hour = 60  minutes, 12 hours = 12 x 6 = 720 minutes]

i.e. Total parts made = [tex]\dfrac{7}{10}\times720[/tex]

i.e. Total parts made = 504

machine B makes parts for 10 hours(=60x 10=600 minutes)

i.e. Total parts made = [tex]\dfrac{16}{15}\times600[/tex]

i.e. Total parts made = 640

Total parts made by both machines = 504+640 =1144

Hence, the total number of parts made by the two machines on Monday=1144.

B) The perimeter of the screen of the iPad Pro is 1.5 times the size of the iPad Mini.
C) The area of the screen of the iPad Mini is 1.5 times the size of the iPad Pro.
D) The area of the screen of the iPad Pro is 1.5 times the size of the iPad Mini.

It’s D, because when using the word “area” it means you have to multiply. The term “times” in this case ALSO means to multiply. The iPadPro is 1.5 TIMES the size of the iPad mini. Hopefully this is correct good luck
