A 12 feet ramp is used to load stuff into the truck which is at a height of 3.5 feet from ground.
The ramp forms a Right triangle with ground and height of truck.
In the Right triangle, hypotenuse is 12 feet and height is 3.5 feet. We need to find horizontal base of right triangle.
We can use Pythagorean theorem that is given by :-
(Hypotenuse)² = (Base)² + (Height)²
(12)² = (Base)² + (3.5)²
144 = (Base)² + 12.25
(Base)² = 144 - 12.25
(Base)² = 131.75
(Base) = √131.75
So, horizontal distance is 11.48 feet.
One liter is 33.814 so do (n x 33.814)
Answer:$570
Step-by-step explanation:
At beginning he had 500
He deposited =134.50+55.50=190.00
Total in account is 190+500=690
He withdrew =64.50+55.50=120.0
Total in account =690-120=$570
Answer:
a. 100 mph
b. 500 mph
Step-by-step explanation:
a.
Let the speed of Lindbergh's plane be x.
Today's planes are 5 times faster, so their speed is 5x.
Today's planes speed is 400 mph faster than Lindbergh's speed.
x + 400 = 5x
5x = x + 400
4x = 400
x = 100
Lindbergh's speed was 100 mph
b. 5x = 5 * 100 = 500
Today's planes fly at 500 mph
So I don’t get this but ima say 10
