Answer:
225 I believe because if he has $90 that is 2/5 so add another 90 whitch is 2/5 as well and divide 90 by 2 and to get 45 which all adds up to 225
Answer:
-7/2
Step-by-step explanation:
lets do math:
this looks pretty hard right,
so lets say our number is called x
this is our equation:
-6=(4x-4)1/3
divide -6 by 1/3 because why not
=-18
-18=4x-4
add 4 to both sides because im smart
-14=4x
divide both side by 4 because im smart again
x=-7/2
lemme check this because i make mistakes a lot.
im right
Answer: 48
Step 1: Find how much 12 is of 48.
12 = 1/4 of 48
Step 2: Multiply 12 by 3 for 3/4.
12 x 3 = 36.
Step 3: Add the numbers.
12 + 36 = 48
Answer = 48
As you said it was dropped so in that case I'll take 78.4 meters as the height..
we know that
h = ut + 0.5*g*t(sqr)
t(sqr) = 78.4/(0.5*9.8) [g = 9.8 ms-2]
t = √16
t = 4
So it'd take 4 seconds
