Answer:

3 years

Step-by-step explanation:

I assume it's simple interest.

I = Prt

132 = 800 * 0.055 * t

t = 132/(800 * 0.055)

t = 132/44

t = 3

Dominic is driving on a long road trip. He currently has 10 gallons of gas in his car. Each hour that he drives, his car uses up
Nostrana [21]

Answer:

(a) Equation: T_n = 11.25 - 1.25n

(b) 7.5 gallons

Step-by-step explanation:

Given

Current Gas = 10 gallon

Every Hour = -1.25 gallon

Solving for (a): An equation for the scenario

This question represents an Arithmetic Progression and will be solved using the following formula:

T_n = a + (n - 1)d

Where

a = 10

d = -1.25

Substitute these values in the formula

T_n = 10 + (n - 1) * -1.25

T_n = 10 -1.25n +1.25

Collect Like Terms

T_n = 10 + 1.25 - 1.25n

T_n = 11.25 - 1.25n

Solving for (b): In this case, n - 3

Substitute 3 for n in T_n = 11.25 - 1.25n

T_3 = 11.25 - 1.25 * 3

T_3 = 11.25 - 3.75

T_3 = 7.5

<em>7.5 gallon of gas left</em>

Please help solve this SAT math problem. I have 4 more like these so need help with this so that I can solve the rest by myself.
stealth61 [152]

The notation just means

(f/g)(-4) = f(-4) / g(-4)

If f(x) = x² + 2 and g(x) = 1 - 3x, then

f(-4) = (-4)² + 2 = 16 + 2 = 18

g(-4) = 1 - 3 (-4) = 1 + 12 = 13

and so

(f/g)(-4) = 18/13
