Angle a and angle b are complementary angles. The measure of ∠a is 42°. Which equation represents this situation with x representing the measure of ∠b ?

Answers

Answer 1

Answer: We know, sum of complementary angles are 90 degrees
So, a + b = 90 [ Equation ]

For solving: Just substitute the value of a = 42
42 + b = 90
b = 90 - 42
b = 48

Hope this helps!

Answer 2

Answer:

Answer:

the answer would be 90 + 42 + = x

How much water was in the pool orgininally?

Answers

To find how much water was in the pool originally, you need to write the function for how fast the water is leaving the pool.

Your function is

y=-8x+b

y is amount of water in the pool

x is how many hours

b is the original amount

Since you know y and x, plug those into the function.

132=-8(6)+b

132=-48+b

b=180

The original amount of water in the pool was 180 gallons.

I didn't mean to reanswer the question, I'm sorry! I didn't see that there was already an answer when I began answering.

-8 gallons/ hour
6 hours
-8 × 6 = -48

132 + 48 = 180 gallons

Let's solve your equation step-by-step.4x+1=5x−2 Step 1: Subtract 5x from both sides.4x+1−5x=5x−2−5x−x+1=−2 Step 2: Subtract 1 from both sides.−x+1−1=−2−1−x=−3 Step 3: Divide both sides by -1.−x−1=−3−1x=3 Answer:x=3

a school store has 1200 pencils in stock and sells an average of 24 pencils per day the manager reorders when the number of pencils in stock is 500. in how many days will the manager have to reorder

Answers

Number of pencils in stock = 1200
Average number of pencils sold by the manager per day = 24
Number of pencils that would be sold before reordering = 1200 - 500
= 700
Then
The number of days after which the manager will reorder = 700/24
= 29.16
So the manager has to reorder after about 30 days. Since the answer comes in fraction of more than 29 days, so it has to be 30 days. I hope the procedure is clear for your understanding.

Answer:

29.16

Answers

Three ratios that are equal to 40/50, 75/100, and 21/18 are 4/5, 3/4, and 7/6. The question is essentially asking you to simplify fractions. For example, 8/10 can also be represented as the ratio 8:10. This fraction can be simplified to 4/5, and the ratio 4:5 is the same as the ratio 8:10.
