Answer:
21 Feet Long
Step-by-step explanation:
You just reverse how you find a percentage.
1) 40 / 100 = .40
2) .40 * 15 = 6
3) 6 + 15 = 21
I did it this way because I need to find what 40% is to 15. But the trailer isn't 40% of the truck, it's 40% longer than the truck. So, we must add those 2 numbers together getting 21 Ft.
Answer:
D, E, F
Step-by-step explanation:
The first step I would do is distribute the original equation. After distributing, the equation is now 8x² + 16xy. The first answer I see that matches this is D.
Then, after already eliminating A, B, and C, I look at E. I distribute the x and find out it is also equal to 8x² + 16xy.
Then, I look at F. After distributing again, it is also equal to 8x² + 16xy.
Answer:
a. 2
Step-by-step explanation:
The given function is
.
We can see from the graph that the graph has two x-intercepts.
This means that the function has two real zeros.
By the fundamental theorem of Algebra, the function is supposed have four roots since it is a polynomial of degree 4.
Therefore, the other two zeros are complex.

Percentage change is 100% increase.
Step-by-step explanation:
- Step 1: Find volume of cylinder A using equation, V(A) = πr²h, where r = 7 in and h = 5 in
⇒ V(A) = π × 7 × 7 × 5 = 245π
and V(B) = 490π
- Step 2: Calculate percentage change from V(A) to V(B)
⇒ % change = [V(B) - V(A)/V(A)] × 100 = (490π - 245π/245π) × 100
= 245π/245π × 100 = 100% increase
