Two friends, Justin and Brooklyn, had just bought their first cars. The equation y=40.9x represents the number of miles, y, that Justin can drive his car for every x gallons of gas. The table below represents the number of miles, y, that Brooklyn can drive her car for every x gallons of gas.
Answers
Answer:
So what is the question?
Step-by-step explanation:
Brooklyn can drive her car 127 miles for every 5 gallons of gas
y = 127 x = 5
y = (127 / 5) miles for every one gallon x
y = 25.4x

The length of each side of a cube is x + 1 inches. What is the volume of the cube in cubic inches?
Answers
Answer:
V = x³ + 3x² + 3x + 1 in³
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ( where s is the side ) , then
V = (x + 1)³
= (x + 1)(x + 1)(x + 1) ← expand second pair using FOIL
= (x + 1)(x² + 2x + 1) ← distribute
= x³ + 2x² + x + x² + 2x + 1 ← collect like terms
= x³ + 3x² + 3x + 1

Three vertices of a parallelogram are shown in the figure below.
Give the coordinates of the fourth vertex.
(-3,9)
(0,-3) (6,-6)
Answers
Given:
The three vertices of the parallelogram are (-3,9), (0,-3), (6,-6).
To find:
The fourth vertex of the parallelogram.
Solution:
Consider the three vertices of the parallelogram are A(-3,9), B(0,-3), C(6,-6).
Let D(a,b) be the fourth vertex.
Midpoint formula:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
We know that the diagonals of a parallelogram bisect each other. So, the midpoints of both diagonals are same.
Midpoint of AC = Midpoint BD
[tex]\left(\dfrac{-3+6}{2},\dfrac{9+(-6)}{2}\right)=\left(\dfrac{0+a}{2},\dfrac{-3+b}{2}\right)[/tex]
[tex]\left(\dfrac{3}{2},\dfrac{3}{2}\right)=\left(\dfrac{a}{2},\dfrac{-3+b}{2}\right)[/tex]
On comparing both sides, we get
[tex]\dfrac{3}{2}=\dfrac{a}{2}[/tex]
[tex]3=a[/tex]
And,
[tex]\dfrac{3}{2}=\dfrac{-3+b}{2}[/tex]
[tex]3=-3+b[/tex]
[tex]3+3=b[/tex]
[tex]6=b[/tex]
Therefore, the fourth vertex of the parallelogram is (3,6).

Express your answer as a mixed number.
Answers
Answer:
Each tank holds 4.33 gallons of water.
Step-by-step explanation:
Gallons of water used to fill tanks = 13 gallons
Number of fish tanks filled = 3 fish tanks
To calculate the amount of water in one tank, we will divide gallons of water used to fill tanks by number of fish tanks filled.
Water in one tank =
Water in one tank = 4.33 gallons
Each tank holds 4.33 gallons of water.

The radius of a cylindrical water tank is 4.5 ft, and its height is 8 ft. What is the volume of the tank?
Use the value 3.14 for it, and round your answer to the nearest whole number.
Be sure to include the correct unit in your answer.

Answers
Formula:
V = πr^2h
V = 3.14 * 4.5^2 * 8
V = 3.14 * 20.25 * 8
V = 508.68 ft^3
508.68 rounded to the nearest whole number is 509
So the volume of the cylinder is 509 ft^3
