Answer:
7 pieces of homework
Step-by-step explanation:
This is an algebra problem. We first need to set up our algebra equation and we are going to find X (The amount of homework Richard submitted)
The algebra equation would be
X+X+2=12
*Combine like terms*
2X+2=12
Subtract 2 to both sides
2X=10
X=5
That means that Richard did 5 pieces of homework. We are not done yet because we want to find the amount of homework Isaac did. Earlier in the problem, it said that Issac did 2 more pieces of homework than Richard. Take Richard's number, 5 and add to 2 to it to get 7 pieces of homework.
Answer:
t = 8.69 s
Step-by-step explanation:
The height h of the rocket in feet above the surface of the lake can be modeled by :
Let we need to find the time to reach the ground. When it reach the ground, h = 0
We need to find the value of t.
t = 8.69 s and -2.45 s
Neglecting negative value,
t = 8.69 s
Hence, it will take 8.69 s to reach the ground.
