Answer:

[tex]y=13\text{ miles per gallon}[/tex]

Step-by-step explanation:

We have the two points: (0, 11) and (3, 50).

And we want to find the rate of change in y relative to x, where x is the gallons and y is the miles.

In simple terms, we want to find the slope between the two points.

So, let's use the slope formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Let (0, 11) be (x₁, y₁) and let (3, 50) be (x₂, y₂). Substitute. Let's also put "miles" in the numerator with the Ys and "gallons" in the denominator with the Xs. This yields:

[tex]y=\frac{50-11\text{ miles}}{3-0\text{ gallons}}[/tex]

Subtract and reduce:

[tex]y=39\text{ miles}/3\text{ gallons}=13\text{ miles per gallon}[/tex]

And we're done!

D.2y square root x/square root y

y + 82 = 10x is the answer.

Answer:

y+72 = 10(x-1)

Step-by-step explanation:

I don't really know why this would be useful for solving a problem; please tell me in the comments of my answer.

Anyway, I would pick a random point that would satisfy this equation. One example would be (1, -72)

Now just plug those 2 numbers into the equation:

y+72 = 10(x-1)

Answer: B

Step-by-step explanation:

To get no solution you need to have 2 sides of the equations that don't match. If you go through B you will end up getting 3x- (11/7)=3x-2 which is not true.

With a corner removed, it doesn't change surface area of the cube as same area is exposed equal to the area of 3 small faces.

With the corner relocated to the top of the cube, it covers the area of one small face but adds up small 5 faces (4 sides and one top). In total the P has more surface area than the Q.

Correct answer choice is C.

Answer:

5 movies

Step-by-step explanation:

Let x denotes number of movies that need to be ready each month for the total fees to be the same from either company.

Monthly membership fee charged by a video store = $7.50

Amount charged to rent each movie = $1.00

So,

total amount charged by the first store = [tex]7.50+(1)x=7.50+x[/tex]

Monthly membership fee charged by another video store = $0

Amount charged to rent each movie = $2.50

So,

total amount charged by another store = [tex]0+2.50(x)=2.50x[/tex]

To find number of movies that need to be ready each month for the total fees to be the same from either company,

solve [tex]7.50+x=2.50x[/tex]

[tex]7.50+x=2.50x\\7.50=2.50x-x\\7.50=1.50x\\x=\frac{7.50}{1.50}\\ =5[/tex]

Answer:

5 times

Step-by-step explanation:

Answer:

5 times

Step-by-step explanation:

So this is called division. To solve this you can either use a calculator, or you can use something called guess and check. Guess and check is what it sounds like, guessing and checking to see if it's correct or not.

The way I would solve it is just do 100/20 which equals 5. You can also just add 20 a certain amount of times. For example you could do 20 + 20 + 20 + 20 which equals 80. So that means you can add another 20 to equal 100

Answer:

D

Step-by-step explanation:

I am pretty sure it is D because it looks like there are 24 edges (8 + 8 + 8)

Answer:

the answer is D trust is D

Answer:

so for one, just put a line horizontal to line 1

part two I'm assuming you do the same as p since it's not asking you to make it perpendicular to line 1.

part three, create going through line 1 (vertical)

part four constructs the same triangle, but just move the points a little so that way it's not overlapping.

Step-by-step explanation:

parallel means not touching

perpendicular means crossing each other paths.

Answer:

-12

Step-by-step explanation:

-132/11= -12

Answer: p = -12

Step-by-step explanation:

divide by 11 on both sides to isolate p, giving you -12

Answer:

65 marbles

Step-by-step explanation:

2:6 = x-20:x using the information in the problem

2x = 6x-120, and therefore x = 30. 30 is the number of green marbles.

We can find that the multiplier is 30/6 = 5. So there will be 5*2 = 10 red marbles. 5*5 = 25 blue marbles.

30+10+25 = 65 marbles total.

Answer: 57.02

130.3 - 73.28 = 57.02

Answer:

1. f > 40 miles/gallon

2. t < 35 degrees

Answer:

For part one the vehicle cannot have less than 40mpg so the equality would be

[tex]f\geq 40mpg[/tex] because the mpg must be greater than or equal to 40mpg.

For part two the temp must be LESS than 35 not including 35.

so we would show that with [tex]t<35F[/tex]

Answer:

Here you go :)

Step-by-step explanation:

0.0125 gallons of 35% solution is needed.

Given that,

Eli wants to combine 0.5 gallons of a 10% acid solution with a 35% solution to make a 15% acetic acid solution.

Eli decides to let v represent the volume of the 35% solution.

We have to find,

How many gallons of 35% solution is needed?

According to the question,

Eli decides to let v represent the volume of the 35% solution.

And 0.5 gallons of 10% acid solution,

the volume of the 15% acid solution is (v +0.5).

Therefore,

0.5 gallons of a 10% acid solution with a 35% solution to make a 15% acetic acid solution.

[tex]\rm = 0.5 \times \dfrac{10}{100} + v \times \dfrac{35}{100} = (v+0.5) \times \dfrac{15}{100}\\\\= 0.5 \times 0.01 + v \times 0.35 = (v+0.5) \times 0.15\\\\= 0.05 + 0.35v = 0.15v + 0.075\\\\= 0.35v - 0.15v = 0.075 -0.05\\\\= 0.20v = 0.025\\\\v = \dfrac{0.025}{0.20}\\\\v = 0.0125[/tex]

Hence, 0.0125 gallons of 35% solution is needed.
