Answer:

We are given that:

variables x and y vary directly, this means that:

y = kx where k is the constant of proportionality

Now, we are also given that:

y = 45 at x = 40.

We will use these values and substitute in the above relation to get k as follows:

y = kx

45 = 40k

k = 45/40 = 9/8 = 1.125

Based on the above calculations, the equation that relates x and y is:

y = 1.125x

Answer:

$301.75

Step-by-step explanation:

$296.00 + $5.75

$23.75

I had to think about that one for a minute..

First step: (16 *5.25) = 84

Second step: (84 + 296) = 380

Third step: (380 ÷ 16) = $23.75

I do hope this was the correct answer you were looking for.

Answer: The real answer is 19/10 or 1 and 9/10

Step-by-step explanation:

Jackie added 1/2 and 1/4 to get 1/8 but in order of operation you have to multiply and divide first . So she should have divided 1/2 by 1/4 and then added that with -1/10 .

Answer:

It’s undefined lol!

Step-by-step explanation:

Answer:

1/0 = 0

Step-by-step explanation:

The fraction bar means "divided by", which means that the fraction 1/0 is 1 divided by 0. Any fraction in which the denominator is 0, is an improper fraction, meaning the answer is always 0. So, 1/0, or 1 divided by 0 is 0.

The graph would be linear since it's .05 every minute, which would mean that every minute it would cost .05 --> adding up minutes. The flat fee at the beginning is trying to trick you up, don't get fooled ;)

Answer:

8%

Step-by-step explanation:

50÷100 = 0.5

0.5×2 = 1

1 student = 2%

2%×4=8%

Answer:

8%

create a proportion:

4/50 = x/100

4(100) = 50(x)

400=50x

8 = x

Answer:Kevin need 14.14 feet of red tape  

Step-by-step explanation:

Given: (Figure Attached)

Area of Square  = 25 square feet

As we know

Area of square = length x width = a x a = 25

a * a = 25

a =  ±5 by taking square root both sides

It means a = 5 as the length can not be negative

Now we know the length of sides of square and as shown in figure we can break the figure in two triangles,

By using Pythagoras theorem on one triangle we will find the length of one line of x and then multiply the x with 2 to get the overall feet of tape.

 =  

=  

x = ± 7.07 It means x = 7.07

Now the total tape required is 2 * x = 2*7.07 = 14.14

Step-by-step explanation:

13.5 x 3 = 40.50, and has i multiplied the rest it gave me higher numbers but it was close to the amount of total money

Answer:

Multiply.

Step-by-step explanation:

2 * 15 = 30

5 * 37.50 = 187.5

6 * 45 = 270

8 * 60 = 480

480 + 270 = 750

187.5 + 30 = 217.5.

First problem: (2 1/2z^2 - 1/2z^2) + (7z +5z) + (4 1/2 - 4)

Answer:

C, 2 1/2

Step-by-step explanation:

First, you’d cross out the 3 and the 6, simplifying the problem to 1*5/2, then you’d multiply across. This should give you 5/2, which simplifies to 2 1/2

3*5/6 = 5/2 = 2 1/2
