Answer:
118 feet
Step-by-step explanation:
h= -16t² + 34t +100
In order to find the height of the rocket after 1 second, we substitute t=1 in the above equation
h= -16(1)² + 34(1) +100
h=-16 + 34 +100
h=118 feet
Thus, the rocket will be 118 feet high after 1 second
Length: 4x
Width: ??
Length x Width: 4x^2 + 12x
Can be rewritten as: 4x(x+3)
Therefore: ?? = x + 3
21 + 39 = 60 minutes ( 1 hour)
So for the remaining time she lifted weights for about 2 hours.
3 hours = 180 minutes
180 - 60 = 120
About 66% of the remaining time Yael used to lift weights.
To be accurate 66.6% ( the last 6 repeating a infinite amount of time aka it doesnt end)
3(x+2)=-5-2(x-3)
3x+6=-5-2x+6
3x+2x=-5+6-6
5x=-5
x=-5/5
x=-1
Answer:
Step-by-step explanation:
Some foundation pieces:
Floor is 30 ft^2
tiles are 3w
Equation:
30=(3w)*10
3=3w
1=w
Now that you know that w has to 1 you can write the formula 30=(3w)×10
