Which equation could be used to solve problems involving the relationships between the angles?A) 90 + (8a + 9) = (11 + 2a)
B) 90 − (8a + 9) = (11 + 2a)
C) (11 + 2a) − 90 = (8a + 9)
D) (8a + 9) − (11 + 2a) = 90

Answers

Answer:

Step-by-step explanation:

Seeing the above angles we conclude that

(11+2a)+(8a+9)=90 (since they are complementary angles)

Subtracting (8a+9) to both sides we get

90-(8a+9)=11+2a

Answer:

The answer is B.) 90 - (8a + 9) = (11 + 2a)

Step-by-step explanation:

90 − (8a + 9) = (11 + 2a)

Complementary angles add to 90°

Cathy has 10 feet of ribbon that she wants to use to make bows. She needs 2/3 foot of ribbon for each bow. She also needs to use 16 inches of the ribbon for another project. How many bows will she able to make with the amount of ribbon that is left?

Answers

13 bows is the correct answer because:

10 feet=120 inches
2/3 foot= 8 inches
so 120-16 is 104 and that divided by 8 is 13.

Destiny works on commission as an office supply saleswoman. She sold a computer that cost $700 and received a $126 commission. What percent of her sale is Destiny's commission?

Answers

To figure out the answer to this problem, you must first ask yourself this:

How much is 126 of 700
or
What is 126 divded by 700

The answer is 0.18.

So, that means that 0.18 or 18 percent might be your answer.

Now, lets try 18 percent of 700, to see if we get 126.

18% times 700

The anwer is 126.

SO:

$126 is 18 percent of 700.

18 percent of her sale is Destiny's commission.

Which strategy should be used to correctly solve this problem? Bill wanted to make a rectangular pool that had an area of 80 square feet. He wanted to put tile around it, but he wanted to use as little tile as possible. What are the dimensions Bill should use for his pool?

A.
Arrange 80 square tiles in different patterns until you get a rectangular shape. Count the number of tiles on the perimeter of this shape.

B.
Make a table showing all possible products of length and width that would equal an area of 80 square feet. Then start calculating the perimeter of each rectangle. Look for a pattern to decrease the number of calculations you have to make.

C.
Write a number sentence that could be used to calculate the area of a rectangle. Use guess and check to find two numbers that when multiplied will give a product of 80.

Answers

B, make a table of possible values

the best way to do it is actually not listed
to have max area with minimu perimiter, try to get the sides as close measure to each other as possible

I would pick B though
