<h2><u>Given</u> :</h2>

Radius of circle - 6mm

Area of circle

<h2><u>Formula Using</u> : </h2>

Area of circle = πr²

<h2><u>Solution</u> :</h2>

Area of circle = π(6mm)²

Area of circle = 36π mm²

Hence, the area of circle is 36π mm²

We know that

Area of circle = πr²

=> π × (6)²

=> π × 36

=> 36π mm²

How many computers must the AB Computer Company sell to break even? Let x be the number of computers.

Eduardwww [97]

Answer:

The Company AB must sell 116 computers to break even

Step-by-step explanation:

we have

$R(x)=1.5x$ -----> equation A

$C(x)=145+\frac{1}{4}x$ ----> equation B

where

C is the cost function

R is the revenue function

x is the number of computers sold

we know that

Break even is when the cost is equal to the revenue

equate equation A and equation B

$1.5x=145+\frac{1}{4}x$

Solve for x

subtract 1/4x both sides

$1.5x-\frac{1}{4}x=145$

$1.5x-0.25x=145$

$1.25x=145$

Divide by 1.25 both sides

$x=116$

therefore

The Company AB must sell 116 computers to break even

At a race, there are 3 rows with 15 people in each row. How many total people are there?

Numerical expression- 15 times 3

(Idk if this helped very much but it's worth a shot)

6. (A/pi = r^2)
7. [(P - 2l)/2 = w]
8. [C/(2pi)= r]
9. (2A/h = b)
10. (E/c^2 = m)

If the probability of rain today is 25%, what is the probability that it will not rain today?

AlexFokin [52]

These two events are complimentary. So P(not rain)=1-P(will rain)
So, 75% is my guess
