Answer:
r = d/2
Step-by-step explanation:
The radius is always the diameter divided by 2. Hope this helps :)
Answer:
48/2 or d/2
Step-by-step explanation:
radius is half the diameter because its starts from the center. so if the diameters 48 feet, you have to divide it by 2 and get 24 feet.

Simplify 3 ( x + 2 ) − 2 ( x 2 + 2x − 4 ).
Which of the polynomials below represents the answer written in standard form?
Select one:
a. - 2x 2 − x + 14
b. - 2 + 7x + 2x 2
c. - 3x 4 + 14
d. 2x 2 + 7x − 2
Answer:
The polynomials that represents the answer is -2x² - x + 14 ⇒ a
Step-by-step explanation:
Let us solve the question
∵ The expression is 3(x + 2) - 2(x² + 2x - 4)
→ Multiply each bracket by the number before it
∵ 3(x + 2) = 3(x) + 3(2)
∴ 3(x - 2) = 3x + 6
∵ 2(x² + 2x - 4) = 2(x²) + 2(2x) + 2(-4)
∴ 2(x² + 2x - 4) = 2x² + 4x + (-8)
→ Remember (+)(-) = (-)
∴ 2(x² + 2x - 4) = 2x² + 4x - 8
∴ 3(x + 2) - 2(x² + 2x - 4) = (3x + 6) - (2x² + 4x - 8)
→ Multiply the (-) by all the terms in the 2nd bracket
∴ 3(x + 2) - 2(x² + 2x - 4) = 3x + 6 - 2x² - 4x + 8
→ Add the like terms
∵ 3(x + 2) - 2(x² + 2x - 4) = -2x² + (3x - 4x) + (6 + 8)
∴ 3(x + 2) - 2(x² + 2x - 4) = -2x² + (-x) + 14
∴ 3(x + 2) - 2(x² + 2x - 4) = -2x² - x + 14
∴ The polynomials that represents the answer is -2x² - x + 14

Answer:
B. 20 = 2g
Step-by-step explanation:
What we see here is a diagram showing a bar of 20 at the top, and a pair of g's bars each taking up half of the 20 bar.
Seeing this, that would mean the 2 bars showing g equal 20, so the equation 20 = 2g is the one which the diagram shows.
Casey's drill team squad was responsible for painting props for a performance at a band contest. The squad painted 18 props in 90 minutes. If they continued painting at this rate, how many props would they paint in 3 hours?
Answer: They would paint 36 props in 3 hours.
Step-by-step explanation:
Given: The squad painted 18 props in 90 minutes.
Time taken to paint each prop = [tex]\dfrac{90\text{ minutes}}{18}[/tex]
= 5 minutes
Now, 1 hour = 60 minutes
3 hours = 3 x 60 minute = 180 minutes
Total props painted in 3 hours = (180 )÷5
= 36
Hence, with same rate , they would paint 36 props in 3 hours.

4x - x, for x=2 WHATS THE ANSWER
If interest is compounded semi-annually, which expression represents the account balance in t yeats?
Answer:
ANNUAL Compounding : Total = Principal * (1 + rate)^years
Semi-Annual TOTAL = Principal * (1 +rate/n)^n*years
where "n" is the number of compounding periods per year
So the formula for semi-annual compounding is
TOTAL = Principal * (1 +rate/t)^t*years

______________________________
1.) Subtract 14 from both sides:[tex]14-14=[/tex] Cancels Out[tex]39-14=25[/tex]- We do this because we have to get 2 variables/numbers on each side of the equals, and the only way to do so is to cancels other numbers out by doing the opposite of what we see.
Equation at the end of Step 1:
[tex]v[/tex] ÷ [tex]-0.8=25[/tex]2.) Multiply both sides by −0.8:[tex]-0.8[/tex] × [tex]-0.8=[/tex] Cancels Out[tex]25[/tex] × [tex]-0.8=-20[/tex]______________________________

List the steps to fom 13x + 2
Answer: 13x + 2 = 41 = 3
Step-by-step explanation:
Step 1: Subtract 2 from both sides.
13x+2−2=41−2
13x=39
Step 2: Divide both sides by 13.

Solve the equation for b. *
(50 Points)
12 = 6 (8) + b
Enter your math answer
Answer:
B=-36
Step-by-step explanation:
First, do 6(8), which equals 48
The you subtract 48 from both sides, which leaves you with:
-36=B
Answer:
b is equal to negative thirty-six.
Step-by-step explanation:
You can solve this by first multiplying the six and the eight. Eight times six is equal to forty-eight. You can then subtract that forty-eight from both sides, leaving you with the expression b = -36:
[tex]12 = 6(8) + b\\12 = 48 + b\\12 -48 = 48 + b - 48\\-36 = b\\b = -36[/tex]

The amount for NET PAY for this pay period was $
Answer:
240.62$
Step-by-step explanation:
$9.75 per hour
30 hours
Total earned: 292.5$
Federal income tax (withholding) at 10% --> 29.5$
Social Security tax at 6.2% --> 18.14$
Medicare tax at 1.45% --> 4.24$
292.5 - all taxes = 240.62$
