Answer:
41
Step-by-step explanation:
These angles are vertical angles, and vertical angles are equal
2x+1 = 7x-99
Subtract 2x from each side
2x+1-2x = 7x-2x-99
1 = 5x-99
Add 99 to each side
1+99 = 5x-99+99
100 = 5x
Divide each side by
100/5 = 5x/5
20 =x
The 2x+1 angle equals
2(20)+1
40+1

What exactly are the spring's properties?
Answer:
A
Step-by-step explanation:
The equation will be in the form
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 5) and (x₂, y₂ ) = (2.5, 0) ← 2 points on the line
m =
= - 2
The line crosses the y- axis at (0, 5) ⇒ c = 5
y = - 2x + 5 or
y = 5 - 2x → A
Answer:
a
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
Area of circle Formula: A = πr²
d = 2r
Simply plug in what you know:
201.0624 = 3.1416r²
64 = r²
r = 8
d = 2(8)
d = 16
