She needs to sell $4,000 worth of merchandise.
If she needs to earn $320, and she earns 8% commission, you’re looking for what 8% of original amount equals $320.
X = original amount
8% = .08
$320 = amount needed
X * .08 = $320.
X = $320/.08
X= $4,000
Kristen needs to sell $4,000 worth of merchandise at an 8% commission rate to earn $320.
Answer:
9x² − 12x + 4
Step-by-step explanation:
A perfect square trinomial:
a² + 2ab +b²= (a + b)²
a² - 2ab +b²= (a - b)²
9x² − 12x + 4 = (3x)² - 2*(3x)*2 + 2² = (3x - 2)²
36b² − 24b + 16
16x² − 24x − 9
4a² − 10a − 25
We know that
the area A of the circular cross section of the pipe is
A=pi*r²
D=20 cm------------- > r=D/2=20/2=10 cm
then
A=pi*10²=100*pi cm²
the answer is A=100*pi cm²
Answer:
16 3/4 miles
Step-by-step explanation:
So the goal of this problem is to get Ryan's total driving distance which was made up of:
A 5 3/4 mile trip
A 6 1/2 mile trip
A 4 1/2 mile trip
Start by adding the last two since they have the same denominator
6 1/2 + 4 1/2 = 10 2/2 = 11
11 miles plus 5 3/4 miles
11 + 5 3/4 = 16 3/4
He drove at total of 16 3/4 miles
Well 1 decagram is 10 grams and 10×2 is 20 so 20 from 25 is 5 so 5 grams was used
