Answer:
0.111
Step-by-step explanation:
20% = 0.20
6 * 0.20 = 1.2
6 + 1.2 = 7.2
Circle B has a radius of 7.2.
Circle Area = pi *r^2
Lets use 3.14 for pi
3.14 * 7.2^2 = Area of circle B
7.2 * 7.2 = 51.84
3.14 * 51.84 = 162.7776
Area of circle B is 162.7776
Rounded to 2 decimals, this is 162.78
A. 189.31
D. 162.78
E. 203.15
are all equal to or grater than 162.78
Answer:
$70
Step-by-step explanation:
Daria's total income = fixed income + variable income
Let
Daria's Fixed income = x
additional $30 if the buyer gets an extended warranty
Daria's variable income = 30s
Where,
s = number of televisions with extended warranties she sells
If Daria sells 15 televisions with extended warranties, she earns \$1,500. Find her fixed income
Daria's total income = fixed income + variable income
1500 = x + 30(15)
1500 = x + 450
1500 - 450 = x
1,050 = x
x = $1,050
Daria's total fixed income = $1,050
How much is the fixed amount Daria for each television?
Fixed income per television = Total fixed income / number of television sold
= 1050 / 15
= 70
Fixed income per television = $70
