Answer:
D. 2,880 feet.
Step-by-step explanation:
You do 775 x 2 + 665 x 2, which equals 2,880 feet.
Area of a trapezoid, A = 1/2 × (a + b) h, where a = 19 cm, b = 23 cm & h = 14 cm.
By substitution, we have
A = 1/2 × (19 + 23)14
= 1/2 × 14(19 + 23)
= 1/2 × 14(42)
= 7(42)
= 294 sq. cm
Answer:
(8, 2 )
Step-by-step explanation:
Given the 2 equations
x + 4y = 16 → (1)
- x + 3y = - 2 → (2)
Adding the 2 equations term by term will eliminate the x- term
0 + 7y = 14
7y = 14 ( divide both sides by 7 )
y = 2
Substitute y = 2 into either of the 2 equations and solve for x
Substituting into (1)
x + 4(2) = 16
x + 8 = 16 ( subtract 8 from both sides )
x = 8
solution is (8, 2 )
X = 30. Plug thirty into the equation to get -11 = -30 + k. Add 30 to both sides to get 19 = k.
K = 19

Answer:
$47.97
Step-by-step explanation:
If Scarlett pays a 17% tip <u>in addition</u> to the price of the haircut, this means that she will pay 117% of the price of the haircut (as the price of the haircut = 100%).
convert percentage to decimal:
117% = 117/100 = 1.17
multiply the cost of the haircut by 1.17:
41 x 1.17 = 47.97
