A) cost = (cost/gallon)*gallons
.. 83.58 = 3.799*gallons
.. 83.58/3.799 = gallons ≈ 22.001
The SUV has a 22-gallon tank.
B) miles per gallon = miles/gallons
.. miles per gallon = (24297 -24033)/((3/4)*22) = 264/16.5 = 16
The gas mileage for the trip was 16 miles per gallon.
When it comes to fractions yes you do. But to make it easier just multiply the denominators and that should give u a common denominator, they don't always have to be least common.
And or both means we multiply the given probability situations that are mutually exclusive and exhaustive - they cannot occur at the same time.
let P(a)=x
then: P(b) * P(a) =3/4
15/16 * x = 3/4
15x/16 = 3/4
therefore x= 3/4 *16/15
x = 4/5
P(a) = 4/5
hope it's clear
A home mortgage is usually D.20-30 years
C^2=a^2+b^2
6^2=5^2+b^2
36=25+b^2
b^2=36-25
b^2=11
b= √11
b=3.3166
If you need to round it to the tenth place,
b~3.3
to hundreds place,
b~3.32
Good luck
