Answer:
Which math do you need to use help?
Answer=B and second graph
To find the length of the skateboard ramp, we need to look at the triangle where the length of the skateboard ramp is a hypotenuse, a horizontal distance is a leg and a vertical distance is a leg also. So we can use Pythagorean theorem.
c² = a² + b²
c² = 17² + 4² = 305
c=√305≈17.46
Answer is 17.46 feet.
This is reverse percentage
8.4% = 420
÷8.4 both side
1% is now 50
1% =50
x100
100% is 5000
Check:
8.4/100 = 0.084 our decimal multiplier
5000 x 0.084 = 420
Thus, x is 5000
Hope this helps!
