Answer:
100
Step-by-step explanation:
4.75×6=28.5
6 cookies= 6x
The expression is 6x+28.5
Answer: $34.78
Step-by-step explanation:
x = 9.21° or x = 22.5°
cot²2x – 4cot2x + 3 = 0
Let cot2x = y
y² - 4y + 3 = 0
Factorizing, we have
y² - y - 3y + 3 = 0
y(y - 1) -3(y - 1) = 0
(y - 1)(y - 3) = 0
y - 1 = 0 or y - 3 = 0
y = 1 or y = 3
Since cot2x = y
cot2x = 1 or cot2x = 3
1/tan2x = 1 or 1/tan2x = 3
tan2x = 1 or tan2x = 1/3
2x = tan⁻¹(1) or 2x = tan⁻¹(1/3)
2x = 45° or 2x = 18.43°
x = 45°/2 or x = 18.43°/2
x = 22.5° or x = 9.21°
So, x = 9.21° or x = 22.5°

Answer:
$0.31.
Step-by-step explanation:
If 1.10 apples cost $3.50, we should divide to find the rate per apple.
1.10/3.5 ≈ 0.31
0.31 is the aproximatley answer, since there is no clear answer (at least not from my work). 0.31*70=21.70
The cost of 70 apples are 0.31.
