Answer: 1.2x
Step-by-step explanation:
Profit = Selling price - Cost
She bought the stock at a cost of x dollars
Her profit was 20% of that, which is 0.2x dollars
Selling price = Profit + Cost = x + 0.2x = 1.2x
Answer:
20. 300π m³
21. 457 1/3 π cm³
Step-by-step explanation:
20. r = 10 ÷ 2 = 5
V = 5² × 12 × π = 25 × 12π=300π m³
21. r = 14 ÷ 2 = 7
V = \frac{4}{3} \pi 7x^{3}
V = 457 1/3 π cm³
Answer:
f(-3) = 15
Step-by-step explanation:
Given that,
f(x) = -x + 12
You have to solve for,
f(-3) = ?
For that,
you have to put (-3) instead of x
f (-3) = -x + 12
= -(-3) + 12
= +3 + 12
= 15
Hope this helps you.

Answer:
y = 1/6x + 5
Step-by-step explanation:
-x + 6y = 30
6y = x + 30
y = 1/6x + 5
Answer:
64.3 m²
Step-by-step explanation:
The figure is composed of a square and a quarter circle.
Therefore, area of the figure = area of the square + area of quarter circle
= s² + ¼(πr²)
Where,
s = 6 m
r = 6 m
Plug in the values
Area = 6² + ¼(π*6²)
Area = 64.274334 ≈ 64.3 m² (nearest tenth)
