Which one of the relationships described is not proportional?

a.
Cedrick earns $9.75 for each day he pet-sits; is the relationship between the money he earns and the days he works proportional?

b.
Marianne is 15 years old and her brother is 5 years old; is the relationship between their ages proportional?

c.
The length of the side of a square and its perimeter; is the relationship between the measurements proportional?

d.
A car travels at a constant speed of 35 miles per hour is the relationship between the distance and the time proportional?

Set up the equation 64.8 = .36x

Divide by .36 on both sides.

You get 180 = x.

36% of 180 is 64.8

Multiply .36 by 180 to double check.

Hope this helps

Answer: Choice A) y = cx

The 'c' is the constant of variation

For example, if c = 2, then y = 2x is a direct variation. Whatever x is, we double it to get y. As x increases, so does y. As x decreases, then so does y. Both x and y increase/decrease together.

Direct variation equations always go through the origin, and they are always linear. The 'c' plays the role of the slope. You can think of y = cx as y = mx+b where b = 0 in this case and c = m.

Answer:

1/2

Step-by-step explanation:

We have to follow the order of operations. Since there are no parenthesis or exponents, we do multiplication first. to multiple fractions, we multiply the two numerators (top parts), which in this situation would get us 5*1=5. Then, we multiply the two denominators (bottom parts), which would get us 8*2=16. then we put the first result over the second, and we get 5/16. since the two denominators are the same, we don't need to change anything. we can just add the numerator, and get 8/16, which simplifies to 1/2.

Answer:

no

Step-by-step explanation:because 117% would be 1.17  and 50/33 is 1.5151...

The fraction can be converted into percentage by multiplying it by 100. The given fraction is not equivalent to 117%.

A percentage is a value that indicates hundredth part of any quantity.

To convert percentage into a fraction it is divided by 100.

The given fraction is 50 / 33

In order to check whether the given fraction is equal to 117%, convert the given fraction to percentage by multiplying it by 100 as follows,

(50 / 33) × 100%

=  50 × 3.33%

=  166.5%

Thus, the given fraction is not equal to 117%.

Hence, 50 / 33 and 117% are not equivalent.

Answer:

18

Step-by-step explanation:

Use the order of operations here to solve your expression.

First do Parentheses, then Exponents, Multiplication and Division, and Addition and Subtraction. An easy way to remember this is PEMDAS.

Let's dive right in,

[tex]-3^{2}-7*-3+6\\-9-7*-3+6\\-9+21+6\\12+6\\18[/tex]

In conclusion, the value of this expression is 18. Hope this helped :D

Edit: fixed an error (did 3^2 instead of -3^2)

Answer:

n = 15

Step-by-step explanation:

4n + 5 + 8n - 5 = 180

~Combine like terms

12n = 180

~Divide 12 to both sides

n = 15

Answer:

A. y = (x - 3)(x + 8)(x - 1)

Step-by-step explanation:

To find zeros of a polynomial, we set the polynomial equal to zero.

We can eliminate C and D; as we set them equal to 0, we see that a root would be 0 due to x. Since we are not looking for a root of 0, those 2 answer choices are incorrect.

Between A and B, A is correct:

A

0 = (x - 3)(x + 8)(x - 1)

x = -8, 1, 3

B

0 = (x + 1)(x - 8)(x + 3)

x = -3, -1, 8

Answer:

Answer A is the correct one.

Step-by-step explanation:

Which function has zeros of -8,1 and 3?  We convert each of these zeros into factors, as follows:  (x + 8), (x - 1), (x - 3).  Answer A is the correct one.

Answer:

[tex]49v^{2} +42v+9[/tex]

Step-by-step explanation:

First, let me say, I'm not sure what exactly the equation is because it's worded weirdly, but I'm assuming it's [tex](7v+3)^{2}[/tex].

(7v+3)(7v+3) [[tex]7v+3^{2}[/tex] is the same as (7v+3)(7v+3).]

[tex]49v^{2} +42v+9[/tex] [When you multiply them, this is the product.]

This is as far as you can simplify without knowing the value of v as far as I know.

Answer:

300 dollars

Step-by-step explanation:

Multiply 10 feet by 12 feet to get the total number of feet needed

10x12=120 feet

120 times $2.5= $300

The cost to carpet a rectangular floor is $300.

Given that,

Based on the above information, the calculation is as follows:

[tex]= 10 \times 12 \times \$2.50[/tex]

= $300

Learn more: brainly.com/question/17429689

The answer is -300 because he owes -225 and then when he spends they subtract the amount he spent so the equation would be -225-75= the answer of -300

Answer:

y=6/4x-3

Step-by-step explanation:

First, you isolate the y, by subtracting 6x from each side. Then, you divide by -4 on both sides to isolate it to an individual y.

Answer:

Slope = 6/4 or 1 1/2

Step-by-step explanation:

Step 1:

6x - 4y = 12       Equation

Step 2:

y = mx + b       Slope Intercept Form

Step 3:

- 4y = - 6x + 12      Subtract 6x on both sides

Step 4:

y = 6/4x + 12        Divide 4 on both sides

Answer:

Slope = 6/4 or 1 1/2

Answer:

a=6

Step-by-step explanation:

1/2a + 1/3a =5

Multiply each side by 6 to clear the fractions

6(1/2a + 1/3a) =5*6

3a +2a = 30

Combine like terms

5a = 30

Divide by 5

Step-by-step explanation:

Answer:

Step-by-step explanation:

given data

let the total charge be y

and let the number of pound be n

also let the charge per pound be p

we know that the expression for the total charges is given as

y=2+np

given that

y=$38

n=9

the expression the charges is now

38=2+9p

solving for p we have

38-2=9p

36=9p

p=36/9

p=4

therefore she is charged $4 per pound
