Answer:
Assuming that v0 represents the initial velocity, then v0 = 96 ft/s. Substitute this value into h(t) and set the equation equal to 48. Then, write this quadratic equation in standard form, which is ax² + bx+ c = 0, where a, b, and c are constants. Either use factoring or the Quadratic Function to solve the equation for t. Remember that t must be positive, because it represents a unit of time.

Answer:
Ava needs to add 50ml of cleaner.
Step-by-step explanation:
Ratio of cleaner : water = 1:7
This means that the total ratio;(water+cleaner) = 1+7 = 8
Find fraction of each item out of the total ratio of 8;
Fraction of water = 
Fraction of cleaner = 
Knowing the fractions, find the quantity of cleaner in <em>ml </em>out of a total of 400-ml;
Cleaner = (1/8 )*400 = 50ml
Therefore, Ava needs to add 50ml of cleaner.

Answer:
Step-by-step explanation:
The system of equations can be written ...
n + d = 20 . . . . . . . . coins in the jar
5n +10d = 130 . . . . . value in cents
_____
Using the first equation, we can write an expression for n:
n = 20 -d
We can substitute this into the second equation:
5(20 -d) +10d = 130
100 +5d = 130 . . . . . . simplify
5d = 30 . . . . . . . . . . . . subtract 100
d = 6 . . . . . . . . . . . . divide by 5
n = 20-d = 14
The jar contains 14 nickels and 6 dimes.
