The balloon reaches a height of 7 feet at 0.1 seconds and 2.13 seconds
<h3>How to determine the time the balloon is at the height?</h3>The equation of the function is given as
h(t)= -16t^2 + 35t + 5
The above equation is a quadratic equation
When the balloon is at a height of 7 feet, we have
h(t) = 7
So, we have the following equations
h(t)= -16t^2 + 35t + 5
h(t) = 7
Next, we plot the equations on a graph (see attachment)
The equations intersect at
t = 0.059 and t = 2.129
Approximate
t = 0.1 and 2.13
Hence, the times are 0.1 seconds and 2.13 seconds

The number of tablespoons of salt jacob mixes with 1 cup of water is 4 tablespoon of salt.
<h3>How to interpret the division? </h3>When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.
Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.
Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.
Thus, divided in b equal parts.
Also, we can write:
(it is since )
The given table is:
Tablespoons of salt Cups of water
8 2
16 4
24 6
2 cups of water gets 8 tablespoon of salt.
Then 1 cup of water gets 8/2 = 4 tablespoons of salt. (divided the numbre of cups of water and number of tablespoons of salts in 2 equal parts).
This pattern remains same for other rows of the table, since we have:
1 cup of water gets 8/2 = 16/4 = 24/6 = 4 tablespoons of salt.
Thus, the number of tablespoons of salt jacob mixes with 1 cup of water is 4 tablespoon of salt.
