Step-by-step explanation:

circumference of a circle :

2×pi×r

area of a circle

pi×r²

r(radius) is diameter/2. = 1.5ft

we shall assume 3.14 to be pi.

so,

circumference is

2 × 3.14 × 1.5 = 3.14 × 3 = 9.42 ft

area is

3.14 × 1.5² = 3.14 × 2.25 = 7.065 ft²

What is the area of a triangle with a base length of 2 1/2 inches and a height of 2 inches

Sedaia [141]

Hello I am happy to help you with this problem. So the formula to solve for a triangle is A = bxh divided by 2.
So it’s area equals base times height divided by 2. So the base is 2 1/2 which becomes 5/2 ( five over 2) times 2 which equals 5. It’s because you cancel. So 5 divided by 2 equals 5/2 which also equals 2 1/2.

I hope that helps you. If you have any questions please feel free to ask me.

Wilcorp has 50 employees who work 40 hours a week and earn $20/hour. Fifteen employees each worked 4 hours of overtime at 50% ab

tatuchka [14]

50 X (40 X$20) = 50 X $800 = $40,000

15 X (4 X (50% X $20+ $50)) = 15 X (4 X $60) = 15 X 240 = $3600

$40,000 + $3600 = $43,600 Total payroll

$3,600/$43,600 = .0825688073 as a percent rounded to the nearest tenth is 8.3%

Translate the following sentence into an algebraic inequality: Three times a number, v, added to eight is greater than or equal

Kazeer [188]

Hi there!

»»————-　★　————-««

I believe your answer is:

$3v + 8 \geq 22$

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

$\boxed{\text{Breaking down the phrase...}}\\\\\text{Three times a number, v, added to eight is greater than or equal to twenty-two. }\\------------------\\\rightarrow \text{"Three times a number, v..."} - 3v \text{ This expresses the product of '3' and 'v'.}\\\\\rightarrow \text{"added to eight..."} - + 8 \text{ The product gets added to eight.}\\\\--------------\\\text{The First Part Is:}}\\\\3v + 8\\---------------\\\rightarrow \text{is greater than or equal to twenty-two. } - \geq 22$

$\text{The value of '3v + 8' is greater than or equal to 22.}\\---------------\\\text{\underline{Putting it together, we would have:}}\\\\\boxed{3v + 8 \geq 22}}$

⸻⸻⸻⸻
