B is the correct answer because 1 gallon of gas is 1.05 dollars, so 15 × 1.05 is 15.75...
Answer:
B.
Step-by-step explanation:
The street sign is composed of two rectangles and 1 triangle.
Painted area = area of triangle + area of rectangle 1 + area of square
✔️Area of triangle = ½bh
b = 15 in.
h = 8 in.
Area of triangle = ½*15*8 = 60 in.²
✔️Area of rectangle 1 = L*W
L = 50 in.
W = 6 in.
Area = 50*6 = 300 in.²
✔️Area of Square = s²
s = 15 in.
Area = 15² = 255 in.²
✅Painted area = 60 + 300 + 225 = 585 in.²
We have the following expression:
(27x 4 - 18x 3 + 9x 2) ÷ 3x
Dividing each term between 3x we have:
9x3 - 6x2 + 3x
We can check the result:
(9x3 - 6x2 + 3x) * (3x)
= (27x4 - 18x3 + 9x2)
Division OK.
Answer:
The result of the division is:
9x3 - 6x2 + 3x
Question 1:
Choir A - 129.5 = 130
Choir B - 130.1 = 130
Choir C - 130.8 = 131
Choir D - 129.8 = 130
Answer - Choir C
Question 2:
132 = 1/2x + 2(x - 9)
= 1/2(60) + 2(60 - 9)
= 30 + 102
= 132
60 - 9 = 51
