Issac has completed two more pieces of homework then Richard who submitted X pieces of homework for the semester if the total nu
Natasha_Volkova [10]

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.

Debbie launched a toy rocket off a hill next to Lake Lakewood. The height h of the rocket in feet above the surface of the lake
jenyasd209 [6]

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 :

h=340+100t-16t^2

Let we need to find the time to reach the ground. When it reach the ground, h = 0

340+100t-16t^2=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.
