An apartment building has a parking lot with 12 parking spaces for tenants. At 6 a.m., all 12 spaces were full. At 8 a.m., the number of cars in the lot had decreased by 4. By 9 a.m., there were no cars left in the lot. Use the number line to show each change in the number of cars in the parking lot. What integer represents the change in the number of cars between 8 a.m. and 9 a.m.?

Answer:

If boys to girls, 5:8. If girls to boys, 8:5.

Step-by-step explanation:

There are 8 girls and 5 boys. That means the ratio could be 8:5 or 5:8. You didn't specify in the question which one, so I can't tell you which one. But, if the question asks for boys to girls, put 5:8. If it asks for girls to boys, but 8:5.

It D: 8x=64

Answer:

D: 8x = 64

Step-by-step explanation:

($8) equals the amount he makes for washing 1 car

($64) is the total amount Zane has made from washing cars

(X) is equal to how many cars he has washed for the total to be $64

Now, all we have to do is write down an equation that shows how we can find how many cars have been washed for him to get his sum of $64.

8 times x (x is equal to the number of cars he's washed) so 8 times something (or x) gives you the amount of money Zane has made which would be the only viable answer to the question.

8 - x = 64 - Incorrect

You would not be subtracting the amount of cars Zane has washed by the amount of money he is making per car.

64x = 8 - incorrect

This would mean you're multiplying the total amount of money Zane has made, by how many cars he's washed, which then equals the amount he makes per car. Doesn't make sense ik.

8 + x = 64 - incorrect

While this could look like a viable answer to what they're asking, don't be tricked. You have to multiply the number of cars Zane has washed by the amount he makes per car, otherwise you would just be adding 8 plus the number of cars he washed which does not equal $64.

Greetings from Brasil...

Exponential equation - objective: to make the bases of the 1st and 2nd members equal

24 = 3 · 2ˣ    let's move from 3 to the 1st member

24 ÷ 3 = 2ˣ

8 = 2ˣ     simplifying 8: 8 = 2³

2³ = 2ˣ    as the bases are the same, we work only with exponents

Answer

13

Step-by-step explanation:

Whenever you have a - - it becomes a +.

So 8 - (-5) becomes 8+5

No it is not the same because you can not reverse division problems the same way you can with multiplication.

5 1/4 / 3 1/2 is asking how many times 3 1/2 can go into 5 1/4. The answer to this would be 1.5

3 1/2 / 5 1/4 is asking how many times 5 1/4 can go into 3 1/2. The answer to this would be .667

Answer:

y= -1x -4

Step-by-step explanation:

So the question is asking for slope intercept form.

y = mx+b is the slope intercept formula

m is the slope (-1) , and b is the y intercept (-4)

When you plug those two numbers into the equation, you get:

y= -1x- 4

Answer:

k = 5

Step-by-step explanation:

-2k = k - 7 - 8

Combine like terms

-2k = k - 15

add 15 to both sides

-2k + 15 = k

Add 2k to both sides

15 = 3k

Divide both sides by 3

k=5

Answer:

Step-by-step explanation:

Given the weekly revenue and cost function

R(d) = 12000

C (d) = 350d + 5000

A firm break even point occurs when the amount of revenue is equal to the cost.

If the company Bridal solution breaks even then C(d) = R(d)

350d + 5000 = 12000

350d = 12000 - 5000

350d = 7000

divide both sides by 350

350d/350 = 7000/350

d = 20

Hence the total number of wedding dressing to be sold by Bridal Solutions for them to break even is 20 dresses.

Answer:

The answer is

Step-by-step explanation:

The distance between two points can be found by using the formula

[tex]d = \sqrt{( {x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-6, -5) and (2, 0)

The distance is

[tex]d = \sqrt{ ({ - 6 - 2})^{2} + ({ - 5 - 0})^{2} } \\ = \sqrt{ ({ - 4})^{2} + ({ - 5})^{2} } \\ = \sqrt{16 + 25} \: \: \: \: \: \: \: \: \: \: \: \: \: \: [/tex]

We have the final answer as

[tex] \sqrt{41} \: \: or \: \: \: 6.403 \: \: \: units[/tex]
