Answer:
Step-by-step explanation:
n + 2 = 3(1/3n + 6)
n + 2 = n + 18
NO NUMBERS....because this equation has no solution
Answer:
7
Step-by-step explanation:
Set up an equation where x is the number
2x = 14
Divide by 2 on each side
x = 7
So, the number is 7.
Answer:
Step-by-step explanation:
we know that
Let
x ------> new battery life
The equation that represent this situation is
convert to mixed number
We are tasked to solved for the length of the ramp having an inclination of 15 degrees with the ground and 10 feet from the end of the ramp to the base of the building of the ground. Using trigonometric properties, we have a formula given an angle and the its opposite sides which is,
sin(Angle)=opposite/hypothenuse
hypothenuse would be the distance or the length of the ramp.
so we have,
sin(15)=10/hypothenuse
Cross-multiply, we have,
hypothenuse=10/sin(15)
using scientific calculator having a DEG mode,
hypothenuse=38.63703
Rounding of in nearest tenth we get,
hypothenuse=38.6 ft
Therefore, the ramp is 38.6 ft long
Answer:
125.6637061 or 125.7
Step-by-step explanation:
V=πr²h
Big: π(3)²(5) = 141.3716694
Hole: π(1)²(5) = 15.70796327
141.3716694
- <u>15.70796327</u>
125.6637061
