Is means equal
of means multiplication
lets say this number is a
so:
24 = 40% x a
40% = 40/100 = 4/10 = 2/5
So then:
24 = 2/5 x a
Multiply by 5/2 on both sides
24 x 5/2 = a
Simplify that:
12 x 5 = a
a = 60
So your final answer would be
Answer:
Step-by-step explanation:
height after x seconds = -16x² - 2x + 600
-16x² - 2x + 600 = 450
16x² + 2x - 150 = 0
8x² + x - 75 = 0
Quadratic formula
x = [-1 ± √(1² – 4·8(-75))] / [2·8]
= [-1 ± √2401] / 16
= [-1 ± 49] /16
= 3, -3⅛
-3⅛ is an extraneous solution, so x = 3 seconds.
