Answer: 8 balloons per box
8x18 + 8x12 = 144+96 = 240
Answer:
Number of leashes Bob can make in 2 hours = 7
Number of leashes Bob can make in 1 hour = 7÷2 = 3.5
Let, Bob takes total x hours.
Number of leashes Nina can make in 1 hour = 4
Let, Nina takes total x hours.
∴ The equation that can be used to find the number of hours it takes bob and Nina to make 60 leashes is given by-
3.5x+4x = 60.
7.5x = 60
This equation can be used to find the number of hours taken by Bob and Nina by putting different values of x and y which satisfies above equation.
Answer: The initial height of the ball is 12 feet.
Step-by-step explanation:
We have the function 
, which models the height (in feet) of the ball after 
seconds.
Then, as the height is in function of the time, we know that the ball is in the initial height when:
So, to find the initial height, you need to substitute into the function:
Therefore, the initial height of the ball is 12 feet.
