Answer:
760usd
Step-by-step explanation:
x-80%x=152
20%x=152
1/5x=152
x=152*5=760usd
1/10 + 2.5/10 = 3.5/10 of an hour to make one bracelet. Then change to 20ths so the numerator is a whole number.
Divide your time available by the time it takes to make one.
21
4 = 420= 15 bracelets
7 28
20
(as a whole number there was no fraction or remainder to round off)
Answer:
Step-by-step explanation:
Answer:
sin θ = 0.98
cos θ = 0.198 (≈ 0.2)
Step-by-step explanation:
The steps described below, please check the calculation carefully again by yourself
radius = OP = 1
y² = ((11/61 - 1)² + (60/61 - 0)²)
= 6100 / (61 x 61) = 100/61 distance between 2 points
h² = y² - x² = OP² - (1 - x)²
100/61 - x² = 1 - (1 -2x + x²) = 2x - x²
2x = 100/61
x = 50/61
h² = 100/61 - (2500/3721) =3600/3721
h = 60/61
sin θ =h / OP = 60/61 = 0.98
cos θ = √1 - sin²θ = 0.198 (≈ 0.2)
