If the diameter is given in a problem, area is computed as

A = (π/4) × D<span>2   where </span><span>π is equal to 3.14</span>

<span>If D (diameter)  of one circular table is 6 ft its  Area is 28 sq ft.</span>

If D of another circular is 8 ft its Area is 50 sq ft.

<span>The difference between the areas of the two tables is, therefore (50-28) or 22 sq. ft.</span>

Hello from MrBillDoesMath!

Answer:

15

Discussion:

Given: measure angle STQ = 7x + 55.  But, as shown, STQ is a right angle so

7x + 55 = 90          => subtract 55 from each side

7x = 90 -55 = 35   => divide each side by 7

x = 35/7 = 5

Since RS = (x+1)    + (2x-1)  where x = 5.

     RS = (5 + 1) + (2*5 -1)

           = 6         + 9

           = 15

I don't know what choice the answer is as your diagram only shows Choice A

Thank you,

MrB

Money is borrowed at 15% simple interest. After one year,$1181.05 pays off the loan. How much was originally borrowed?
marin [14]

Answer: $787 was originally borrowed.

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the loan.

P represents the principal or amount taken as loan

R represents interest rate

T represents the duration of the loan in years.

From the information given,

Total amount = $1181.05

Interest = total amount - principal

I = 1181.05 - P

R = 15%

T = 1 year

Therefore,

1181.05 - P

Therefore,

1181.05 - P = (P × 15 × 1)/100

1181.05 - P = 0.15P

P + 0.15P = 1181.0

1.5P = 1181.05

P = 1181.05/1.5

P = $787
