Yes, they are all per something so yes
Answer:
1.57 radians
Step-by-step explanation:
Divide both sides by 360, you get 1° = π/180. This means 70° is equal to (70)(π/180). Then simplify this, and 70° = (7π)/18 radians, or approximately 1.221730476396 radians. This seems reasonable because 90°, is a quarter circle and (1/4) of 2π is π/2, which is approximately 1.57 radians.
The answer would be 16/75
-5x+y=-3
3x-8y=24
Substitution method. Solving for the first equation, because it's easy.
y=-3+5x
Plugin to the other equation.
3x-8(-3+5x)=24
Simplify: 3x+24-40x=24 (Remember, multiplying negatives makes it positive.)
Simplify: -37x + 24 = 24
Subtract: -37x = 24-24
-37x=0
x=0
Plug back into the first:
y=-3+5(0)
y=-3+0
y=-3
Option A
You would have 575 dollars in 8 years
