write a percent between 25percent and 50 percent then write it as a decimal and as a fraction in simplest form

1 answer:

8 0

A percent between 25 and 50 can be 35%

35% as a decimal is 0.35

35% as a fraction = 35/100

35/100 simplest form = 7/20

hope this helps

Answer: s = 36

Step-by-step explanation: The key to solving multistep equations is isolating the variable. This is why I first subtracted 14 on each side. This left me with 1/3s=12. Then, to isolate "s" even more, I didvided by 1/3 on each side. This gave me s = 36 as an answer.

To divide by a fraction, use "keep change flip." Keep the first mumber, change division to multiplication, and flip the fraction. I included a picture of me doing this.

PLEASE HELP!!!!!! I need help on this problem

Thepotemich [5.8K]

Answer:

185 minutes.

Step-by-step explanation:

It is possible to model an equation for this, such that

$0.10x + 14.80 = 0.08x + 18.50$

where x represents the number of minutes.

Then, you solve for x:

$0.10x + 14.80 = 0.08x + 18.50 \\ 0.02x = 3.70 \\ x = \frac{3.70}{ 0.02} \\ x = 185$

A brick wall will be shaped like a rectangular prism. The wall needs to be 3ft tall and the builders have enough bricks for the

faltersainse [42]

Answer:

For a rectangular prism that has a base area B, and a height H, the volume is:

V = B*H

This is the only "tool" that we need to use in this situation.

We know that the wall needs to be 3ft tall, then H = 3ft

And we also know that we have enough bricks for a wall of a volume:

V = 330 ft^3

If we replace these two in the volume equation, we get:

330ft^3 = B*3ft

Now we can solve this for B, and thus find the volume of the base of the wall.

To do it, we just need to divide both sides by 3ft

(330 ft^3)/3ft = B*3ft/3ft

110 ft^2 = B

This means that the area of the base is 110ft^2

As the base is a rectangle of width W and length L, we must have:

110ft^2 = B = L*W

Then the possible measures of the base are given by the linear relation:

L = 110ft^2/W

Where we also need to add some trivial restrictions, like:

L > 0 ft

W > 0ft

This only means that we can not have a length or width equal to or smaller than zero, as those do not have physical sense.
