Answer:
44.6 mph
Step-by-step explanation:
200.7/4.5=44.6 mph
3x^2 + 4x - 21x - 28
x(3x + 4) - 7(3x + 4)
(3x + 4) (x - 7)
Answer: B).
What is the system? (Is there supposed to be an image?)
There are numerous important information's already given in the question. Based on these information's, the answer can be deduced.
Let us assume the age of Daniel = x years
Let us assume the age of Kevin = y years
Then
y = 4x
and
y = x + 6
So
4x = x + 6
4x - x = 6
3x = 6
x = 6/3
= 2 years
So
Age of Kevin = 4 * 2 years
= 8 years

Formula
---------------------------------------------------
Volume of the paint = πr²h
---------------------------------------------------
Find Volume of the paint in the bucket
---------------------------------------------------
Volume of the paint = 3.14 x 3.5² x 8 = 307.72 in³
---------------------------------------------------
Find the cost of the paint
---------------------------------------------------
1 in³ = $0.05
307.88 in³ = $0.05 x 307.72
307.88 in³ = $15.39 (nearest hundredth)
---------------------------------------------------
Answer: The paint cost $15.39
---------------------------------------------------
