when full the gas tank of a car holds 15 gallons. it now contains 12 gallons. what percent represents how full the tank is?
Masteriza [31]

Hello!

to find the percent of a whole, use this equation here:

(remaining) / (total) = X

X * 100 = %

in this case:

12 / 15 = 0.8

0.8 * 100 = 80

your answer is 80%

I hope this helps, and have a nice day!

What is the minimum number of x intercepts that a polynomial of degree 11 can? have?
stiks02 [169]

The degree of the polynomial will tell you the max amount of zeros you will have. 11 in this case.

However you can also have 9,7,5,3,1 (keep subtracting by 2)

So the answer is 1.

H. Goes through (-3, -2) and parallel to y = 5 x +5
olchik [2.2K]

Answer:  y = 5x + 13

<u>Step-by-step explanation:</u>

Parallel means it has the same slope.  

Given line y = 5x + 5  --> the slope is 5, so parallel slope is 5

Use the Point-Slope formula: y - y₁ = m(x - x₁)  such that

  • m = 5
  • (x₁, y₁) = (-3, -2)

y + 2 = 5(x + 3)          <em>input m and (x₁, y₁) into the Point-Slope formula</em>

y + 2 = 5x + 15          <em>distributed</em>

     y = 5x + 13          <em>subtracted 2 from both sides</em>
