Answer 1

Answer:

The first answer is 3) 9(3r-4) and 27r-36

The second answer is 2) Y squared - 36/6

The third answer is 1) 300

Step-by-step explanation:

First answer :

Equivalent expressions are expressions that work the same even though they look different.

9(3r-4) is equal to 27r-36.

9 x 3r = 27r

9 x 4 = 36

27r-36

Second answer :

"The square of y decreased by quotient of 36 and 6" Explains the answer which is Y squared - 36/6

Third answer :

The formula you want to follow is: 2(LW+WH+HL)

2(LW+WH+HL) = 2(12x9+9x2+2x12)

2(12x9+9x2+2x12) = 300

A landscaping company sells 13 bushes and 4 trees for $616.
Write an equation to represent the situation.

Answers

13x + 4y = 616

X represents bushes and y represents trees

Answer:

13x + 4y = 616

Step-by-step explanation:

To begin, lets start with what we know

13 trees + 4 trees = 616

So, let's have the trees as x, and the bushes as y, and we get the equation

13x + 4y = 616

This problem only asks us to create an equation, so that is the answer!

Answer:

the cost for labor was 24.5$ per hour

Step-by-step explanation:

First, I subtract the charge for parts from the total price of the repair.

- 309.50$ minus 187$ = 122.5$

Then, I divide 122.5 by 5 hrs of the labor.

122.5$/5 hrs = 24.5$

Therefore, the cost for labor was 24.5$ per hour for 5 hours of labor

100 divided by 60 plus 40 minus 10 = 31.6666666667

What is the radius of a circle with the circumference 9pi

I urgently need help with this plssss

Answers

Answer:

The radius is 4.5

Step-by-step explanation:

Hello!

The circumference is calculated by the formula: 2πr

r = radius

We need to solve for r, given that 9π is the circumference.

Solve:

9π = 2πr =>Divide both sides by 24.5π = πr =>Divide both sides by π4.5 = r

The radius of the circle is 4.5 units

We will see that the radius of the circle is 4.5 units.

How to get the radius of a circle?

For a circle of radius R, the circumference is given by:

C = 2*pi*R

In this case, we know that the circumference is equal to 9pi, replacing that in the above equation we get:

9pi = 2pi*R

Dividing both sides by pi gives:

9 = 2*R

9/2 = R

4.5 = R

So we can conclude that the radius of the circle is 4.5 units.

I do not believe it is correct.

As time goes by, so does the inch. But, it says that only 1/4 falls, not 1 1/2. Say Y is constantly one. At hour one, it should be 1 1/4. At hour two, it should be 1 2/4 (or 1 1/2). At hour three it should be 1 3/4. At hour four, only now will it become 2 inches. They added to many in this table.

there is 80 people how many people will there be if there was 75% more people?

Answers

Answer:

we have to add 75% of 80 into 80

so 75% of 80 is 60

now add 60 into 80 we get

80 + 60 = 140

so new population is 140

Answer:

Step-by-step explanation:

Note that 1.75 = 1.00 + 0.75. The 1.00 is the original amount and the 0.75 the increase. To answer this question, multiply (80 people) by 1.75: 140

140 is the final number of people.

7, 9, 100 explanition I just took this test and got a 100%

wouldn’t it just be half? half of 6 is 3 half of 30 is 15

Can you please fill out this table?

Answers

If I right understood, there are needed to translate it as a percentage. It’s not hard. For example: If 500 is 100%, then the 50% is 1/2 from 100%, I.e. 50% from 500 is will be 250, because, it’s 1/2 from all sum.

When calculating percentages, it is most convenient to first calculate 1 percent of the number. From 500 it will be 5%, because 100% of 100 is 1, and 500 divided by 100 will be 5. Just solve a little problem with percentages and you will solve it without thinking.
