Answer:

r = \frac{31.4}{\pi}

Step-by-step explanation:

First you have your equation: 62.8 = 2\pir

Divide both sides by 2 because you are looking for r.  You will get:

31.4 = \pi r

Now divide both sides by pi to get:

r = \frac{31.4}{\pi}

1st question: Reuben received 80 dollars. Write a signed number to represent this change.
lesya692 [45]

Answer:

1) +80

2) -1520

Step-by-step explanation:

Positive Signed numbers are used in real world situations to indicate the increase. Examples include; increase in weight, deposit of money into an account, increase in income, profit, height above sea level, etc. They are all represented by positive signed numbers.

Whereas, negative signed numbers show decrease. Examples include; loss of weight, withdrawal of money from an account, loans, liabilities, losses, temperature below zero degrees, height below sea level.

1) We are told that Reuben received 80 dollars. Thus, it means he received an increase in the amount of money he already had. Thus, the signed number will be +80.

2) We are told that A car corporation produced 1520 fewer cars this month than last.

Thus, the signed number will be negative since there is a decrease in number of cars.

Thus, signed number = -1520

What is the value of m?
Dima020 [189]

\huge \underline \mathcal{Answer}

The given angles forms linear pair, and we know the angles forming linear pair are supplementary,

Therefore,

Angle MHJ + Angle MHL = 180°

Let's solve :

  • (5m + 100) \degree + (2 m + 10) \degree = 180 \degree

  • 7m + 110 \degree = 180 \degree

  • 7m = 70 \degree

  • m = 10 \degree

Value of variable m = 10°
