B.





8π square inches
























 



C.





64π square inches
























 



D.





16π square inches

Answers

Answer 1
Answer: You would divide the diameter in half to get the radius which is 4. And do the formula which is a=pie(r) squared. So the answer would be 50.24
Answer 2
Answer: Diameter of a circle = 2r
an area of a circle =  πr²
so, if the diameter of the circular pan is 8 inches taht menas,
2r = 8
or, r = 4 inches
so area of the pan = πr² = 22/7* 4 = 12.57 inches

160/5g or 315/9g show me wat u did so i can understand

Answers

Answer=315/9g

160/5g vs. 315/9g

To find out which one is greater, simply divide the numerator by the denominator.

160/5g=32

315/9g=35

The one with the highest value is the largest, so 315/9g is greater.

Find the inverse of the function d(x) = 2x - 4

Answers

Answer:

d(x) = 1/2x + 2

Step-by-step explanation:

Swap x and y:

x = 2y - 4

Add 4 to the other side:

x + 4 = 2y

Divide by 2:

y = 1/2x +2

Answer:

see explanation

Step-by-step explanation:

let y = 2x - 4

Rearrange making x the subject, add 4 to both sides

2x = y + 4 ( divide both sides by 2 )

x = (y+4)/(2)

Change y back into terms of x, hence

f^(-1)(x) = (x+4)/(2)

A necklace has 6 fewer metal beads than plastic beads.Complete the table to show the number of metal beads, a, and the number of plastic beads, b.
Function: a = b - 6.

Answers

b=6 ⇒ a=0
b=7 ⇒ a=1
b=8 ⇒ a=2
b=9 ⇒ a=3
Since your function is a =b-6 then your graph should look like this                         b                      a

Sales tax is added to the price of items sold on eBay. If someone in Arizona buys an item online for $22.50 and the state sales tax rate is 6.6%, what is the final selling price

Answers

Price of the online item bought by someone in Arizona = $22.50
Percentage of state sales tax that needs to be paid = 6.6%
Then
Amount of sales tax that needs to be paid = (6.6/100) * 22.50
                                                                    = 148.5/100 dollars
                                                                    = 1.48 dollars
So
The final price that needs
to be paid for the online item = (22.50 + 1.48) dollars
                                              = 23.98 dollars

money in a particular savings account increases by about 6% after a year. how much money will be in the account after one year if the initial amount is $100? $50? $200? $125? x dollars? if you get stuck, consider using diagrams or a table to organize your work.

Answers

FIRST STEP)

You have various initial capital C for it, the rate of interest is 6%, and the time is n = 1 year

second step

using the formula  M = C [1+(i*n)] you calculate the values,

M1= 100[1+(0,06 *1)] = 106

M2= 50[1+(0,06*1)] = 53

M3= 200(1,06) = 212

M4 = 125(1,06) = 132,5


$100 $50  $200 $125


$106 $53  $212  $132,5
