Christopher put 12 gallons of gas in her car. She uses one gallon for every 20 miles he drives.

a. Write an equation to represent the total amount of gas left in his car based upon how many miles she has driven.
b. Find the slope and y-intercept.

Answers

Answer 1

Answer:

Equation: y=(-1/20)x+12.

Slope: -1/20

Y-intercept: (0, 12)

Step-by-step explanation:

Let x=the number of gallons of gas in Christopher's car.

If we start with 12 gallons, we have the equation: y=(-1/20)x+12.

This equation is already in slope intercept form, so we see that the slope is -1/20, and the y-intercept is (0, 12).

Let me know if this helps!

Describe two ways the Distributive Property can be used to write equivalent expressions.

Answers

For example, apply the distributive property to the expression 3 (2 + x) to produce the equivalent expression 6 + 3x; apply the distributive property to the expression 24x + 18y to produce the equivalent expression 6 (4x + 3y); apply properties of operations to y + y + y to produce the equivalent expression 3y.

The two ways for the Distributive Property can be used to write equivalent expressions is explained below:

Distributive Property:Here we apply the distributive property to the expression 3 (2 + x) to generate the equivalent expression 6 + 3x.Now apply the distributive property to the expression 24x + 18y to generate the equivalent expression 6 (4x + 3y)

step by step thanks you

Answers

The answer is a and b.

Here's the way to check:

Since all the numbers follow a constant sequence, it is possible to use division. Minus the first term, then divide it by the pattern of the sequence.

For a, 512 - 8 = 504

The pattern from a is each number is increased by 7. So,

504 ÷ 7 = 72

The number itself you count is not important. The point is that the number could be divided fully without remainder. This means 512 will appear in the sequence.

Repeat the above steps for b and c:

512 - 23 = 489

489 ÷ 3 = 163

It can be divided without remainder, 512 appears in this sequence.

512 - 12 = 500

500 ÷ 12 = 41.66666

Since C is a decimal ( there is remainder ), the number 512 does NOT appear in the sequence.

However, if you want to know the logic of WHY this works, I won't be able to give you a satisfying answer. Hope this helps you.

Hello!

Height of pyramid = 845 feet

Slant height = 856 feet

width = 175 feet

The surface area of a pyramid = The base area of the pyramid added to the area of the 4 triangles.

The volume of a pyramid = 1/3 base area * height

1 Triangle = 1/2 base * height

Triangle = 1/2 * 175 * 856 feet

1 Triangle Area  = 74,900 feet

The area of 4 triangles = 299,600 feet

Now, the area of the base = is 175 * 175 feet

Base area = 30,625 feet

Surface area = 30,625 + 299,600 feet = 330,225 feet

Volume = 1/3 * Base area * height of pyramid

Volume = 1/3 * 30,625 feet squared * 845 feet

Volume = 1/3 * 25,878,125 feet cubed

Volume = 8,626,041.(6) feet cubed

Drew wants to wallpaper his bedroom. The room is 10 ft long, 12 ft wide, and 8 ft tall. How many square feet of wallpaper does he need? So I got this question wrong and is wondering how I can get 352 square feet as my answer since that is what my teacher got and I don't know she got that so can someone plz help explain.

Answers

Answer:

you have four walls. two of them 12*8 and the other two are 10*8 ( we used 8 in both because it's the height of the room). so it goes( 2*12*8)+(2*10*8) and it goes 352S

Step-by-step explanation:

let's say that walls A 12*8 and walls B 10*8. you have 4 walls ta wallpaper.

for walls A= 2*12*8=192

for walls B=2*10*12=160

in total, you need 160+192= 352 square feet of wallpaper
