-50+75=25

Answer:

14 inches

Step-by-step explanation:

Using this information, we can form an equation.

Since there are 3 sides in a triangle, and each side increased by 6, that means that the perimeter increased by 18 inches. Down below, I did 3x because there are 3 sides in a triangle.

(This is the equation you'd want to do to get the answer)

3x + 3 * 6 = 60

Simplify:

3x + 18 = 60

Same to both sides

3x = 42

Isolate x:

x = 14

Answer:

11%

Step-by-step explanation:

it is a simple question, whenever you need to find % increase or % decrease.

always divide the increase as in this case $2 by the original amount which is $18 and multiply it by 100 as you need to take the %.

so,

2/18*100 gives you 11.11%      * is multiply  

Step-by-step explanation:

$20 - $18 = $2

to get % of increase we need to know what % of $18 the $2 are.

$2 ÷ $18 = 0.11111111........

Multiply this number by 100 and you will get the percentage.

0.111111111111........ x 100 = 11.1111111111....%

Step-by-step explanation:

Answer:

z = [tex]\sqrt{117}[/tex]

Step-by-step explanation:

find 'y' first by using the altitude rule:

y/4 = 9/y

cross-multiply:

y² = 4(9)

y² = 36

y = [tex]\sqrt{36}[/tex] = 6

Find 'z' by using the Pythagorean Theorem with legs equal to 6 and 9

6² + 9² = z²

36 + 81 = z²

117 = z²

z = [tex]\sqrt{117}[/tex]

Answer:

A. 36

Step-by-step explanation:

A composite number is a number that can be divided evenly by more numbers than 1 and itself. It is the opposite of a prime number. The number 36 can be evenly divided by 1, 2, 3, 4, 6, 9, 12, 18 and 36, with no remainder. Since 36 cannot be divided by just 1 and 36, it is a composite number.

Answer:

Step-by-step explanation:

Hello!

I think I can help.

Lets use the first problem and walk through it and I think it could help you with the others.

3/7 = ?/49

So basically with these problems you are working backwards. You are working right to left and dividing to figure out what you will need to multiply the other part of the fraction by.

So here we have 49 and 7 that line up with each other. (Always look for the fractions that line up horizontally)

Going right to left and dividing :

49 / 7

= 7

So we know that it was 7 x 7 to get that 49

So now we used the number we just found by dividing (7) and multiply it left to right by the other number to find the missing number (?).

If we do this we do :

3 x 7

= 21

And that is the missing number !

We plug that in right where the blank is (?) and we get :

3/7 = 21/49

I am not sure if you have to simplify this but you cant anyways. If you have questions about simplifying ask in the comments.

To check this we can actually multiply the side that had two numbers to begin with (the left side numbers) and multiply it by the number we found by dividing (7).

So we do this with 3/7 :

3 x 7 = 21

7 x 7 = 49

if we plug this back in we get :

21/49 = 29/49 and we know this is correct.

I hope this helps you solve the other problems. If you have any questions or are still confused with others please message me or comment and I will do what I can to help.  :)

Answer:

A. 3

Step-by-step explanation:

The formula for slope is (y2-y1)/(x2-x1), for two points (x1,y1) and (x2,y2) on the line.

Our points are (-1,-1) and (1,5):

(5-(-1))/(1-(-1))

6/2

3

The slope of the line shown below is 3.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

We have,

Points from the graph (1, 5) and (-1,-1).

So, the slope of line

= (-1 - 5)/ (-1 - 1)

= -6 / (-2)

= 3

Thus, the slope of line is 3.

Answer:

25

Step-by-step explanation:

I gallon is 4 quarts so that would be a 600 quarts oil tank so since each case is 24 quarts 600/24 = 25

150 gallons of oil is equivalent to 600 quarts. A full 150-gallon oil tank can yield 25 full cases, with each case containing 24 quarts

The concept used to solve the problem is conversion:

The conversion factor that 1 gallon is equal to 4 quarts.

Given that,

Job: Fill quart-size bottles of oil from a full 150-gallon oil tank.

Packaging: Pack 24 quarts of oil in a case to ship to a store.

Tank Capacity: The oil tank is full and has a capacity of 150 gallons.

Convert the measurements to a common unit.

Since we have to fill quart-size bottles,

Convert 150 gallons to quarts.

Since 1 gallon is = 4 quarts,

So 150 gallons would be 150 x 4 = 600 quarts.

To determine how many full cases of oil we can pack from 600 quarts. Each case contains 24 quarts.

To find the number of cases,

Divide the total number of quarts by the number of quarts per case:

600 quarts ÷ 24 quarts/case

= 25 cases.

Therefore,

You can get 25 full cases of oil from a full 150-gallon oil tank.
