Answer:

3/1

Step-by-step explanation:

Answer:

Has the form y = kx

( y = 0.11x)

(y = 0.04x)

Can be put into form y = kx

(z/x = 9)

Other

(5 = xy)

( x = y/2)

Step-by-step explanation:

y = kx

( y = 0.11x)

(y = 0.04x)

kx = y

(z/x = 9)

-----------

( x = y/2 )

( x - 5 = y)

(5 = xy)

Answer: .1.) 28.8

9.) 150 ft

8.) 630 ft

10.) 5'10"

Step-by-step explanation:. Ratios set up as fractions. 12/25 :x/60

cross multiply. 12 × 60 = 720. Divide by denominator if left side.

720/25 = 28.88

Answer:

Your pay rate is:  

$ 7  per hour

Your friend's pay rate is  :

$ 9  per hour

Explanation:

So if it takes you  8  hours to make  $ 56 , you can just divide the total money earned by the time.  So it would be  56 ÷ 8  which is  7 .

And if takes your friend  4  hours to make  $ 36 , you can divide like we just did . So it would be  36 ÷ 4  which is  9 .

So you make  $ 7  per hour and your friend makes  $ 9 per hour.

Answer:

162.06

Step-by-step explanation:

sorry i'm not the best an explaining but i'm confident in my answer.

the first thing to do is get rid of the ² in x²+y²=24, we do this by √24 which ≅4.90 (i rounded to the hundreth place)

then we have this

x-y=6

x+y=4.90

I am using the elmination method. To do that you need to get two letters to have the same coefficient (in 4x 4 is the coefficient) with oposite signs (one possitive one negitive)

In our equation here we see that the same coefficient is 0, and there is oposite signs for y. Therefore we can add the two equations and get

2x=10.9 (the y cancels out)

now we have a simple equation and all that is left is to solve it

10.9/2=5.45

x=5.45

Now we need to find y we do that by pluging the x value into one of the equations I choose the first one becasue its easiest.

(5.45)-y=6  

y= - .55

now that we have both x and y plug them into the final equation (5.45)³-(-.55)³= 161.89-(-.17) =162.06

Therefore x³-y³≅162.06!

Probably C

Step-by-step explanation:

Repeating Decimal: a decimal where a number or a pattern of numbers repeats forever

For example, 0.2222... or 0.671671....  (The "..." means that it repeats like that forever)

A. 3/7=  0.142857142857142857... (6 repeating digits)  This is a repeating decimal because the last six digits continue forever

B. 3/4=0.75. This number is not a repeating decimal because a repeating decimal goes on forever, while this only has two decimal places.

C. 1/9= 0.11111... This is a repeating decimal because it goes on forever and has a pattern (all are 1s)

D. 5/11=0.454545... This is also a repeating decimal because the last two digits repeat forever.

There is probably something wrong with the question (or your unit) because three of these numbers are, in fact, repeating decimals. If I were you, I would ask your teacher (it gets you respect from the teacher=more chance that they'll be lenient with you)

But if you really don't want to, I would go with "C" because it only has one repeating decimal place, and your curriculum probably says that a repeating decimal is only one digit.

Good Luck! :)

Answer:

y= -x + 225

Step-by-step explanation:

it has a negative slope so -x

it crosses the y axis at (0,225)

so put it together and you get -x+225

Answer:

16y - 4

Step-by-step explanation:

4y(4y - 4) - 4(- 4 + 5 + 4y^2)

16y - 16y - 4(1 + 4y^2)

16y - 16y - 4(4y^2 + 1)

16y^2 - 16y^2 + 4

16y - 4

Answer: 42

Step-by-step explanation:

Answer:

29.25

Step-by-step explanation:

This is a simple function table we are working with, so we see that 2 (pounds) would cost around $4.50. So Next we look at 4 would equal $9. By doing this I divide 9 by 4 to get the answer of 2.25. This is are new function table rule of C=P x 2.25. Now that we have this we know that 13 is are P (pounds) and we are looking for are C (cost) After we input 13 into are function rule. We get the answer of $29.25.

Answer:  well 14 pounds cost $31.50

so that means 13 pounds cost $29.50

Step-by-step explanation:

Answer:

43

Step-by-step explanation:

P-arentheses

E-exponent

M-multiply

D-divided

A-dd

S-ubtract

parentheses first so 8x5 equals 45. 3x2 equals 6. 45 minus 6 equals 39. 39 plus 4 equals 43!

Answer: x = 13.5

3/4 = x/18

⇔ x = 3/4 .18 = 27/2 = 13.5

Step-by-step explanation:

Answer:x = 27/2

Step-by-step explanation:

Step 1: Cross-multiply

3/4=x/18

(3)*(18)=x*(4)

54=4x

Step 2: Flip the equation.4x=54

Step 3: Divide both sides by 4x/4=54/4x

= 27/2

I hope it helps you!
