Answer:
Total = $49.05
Step-by-step explanation:
cost of grapes per pound = $ 2.50
she bought 3 pounds of grapes
so cost of 3 pounds of grapes = 3 × 2.50
= 7.5
gallon of milk = 8.6 pound
so cost of 8.6 pound of milk = 8.6 × 4.25
= $36.55
$ 1.50 off means =$4 - $ 1.50 = $2.5
cost of 2 boxes of cereal = 2 × 2.5
= $ 5
Total = 7.5 + 36.55 + 5
Total = $49.05

average rate of change of work from max. height unitil it reaches the ground 4 ≥ t .
<h3>WHAT IS AVERAGE RATE ? </h3>
The average rate at which one quantity changes in relation to another's change is referred to as the average rate of change function. A method that determines the amount of change in one item divided by the corresponding amount of change in another is known as an average rate of change function.
<h3>CALCULATION</h3>
h(t)=-16t^2+144t
= 16t [ 4 - t ]
4 - t ≥ t
domain is (0,4)
t is the time , time must be positive so domain starts from zero .

Answer:
a= 4
b= -1
c= 10
Step-by-step explanation:
First we start by multiplying both sides of 1/2c = 5 by 2.
c = 10
Add b to both sides of the last equation to make it a=b+5
knowing these two things, we can plug them into the first equation like this:
2(b+5) + b + 10 = 17
then you solve for b:
distribute the 2
2b + 10 + b + 10 = 17
combine like terms
3b + 20 = 17
subtract 20 from each side
3b = -3
divide by 3
b = -1
then you can plug that into the last equation again so a - (-1) =5
Subtracting a negative is the same as adding so its a + 1 = 5 or a = 4
