An individual is printing new IT manuals for a staff of 30. The IT manuals are 120 pages each. If each ream of paper is 300 pages, how many reams of paper does the individual need to put in the printer to get the job do
Answer:12 reams if there are no printing issues and no pages have to be reprinted
Step-by-step explanation:
The number of reams of paper that the individual need to put in the printer to get the job done will be 75.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
An individual is printing new IT manuals for a staff of 30. The IT manuals are 120 pages each. If each ream of paper is 300 pages.
Let 'x' be the number of reams of paper. Then the equation is given as,
x / 300 = 30 / 120
Simplify the equation, then we have
x / 300 = 30 / 120
x / 300 = 1 / 4
x = 300 / 4
x = 75
The number of reams of paper that the individual need to put in the printer to get the job done will be 75.

Mark cycles from home to school at a speed of 16 kilometers per hour. He cycles back on the
same route at a speed of 15 kilometers per hour. The total time taken for the journey is 7 3/4
hours. Given that the distance for his home to school is d kilometers, and that distance -
speed - time, write and solve an equation to find the total distance traveled by him.
Answer:
Write a time equation, time = dist/speed
:
go time + return time = total time
d%2F16 + d%2F15 = 7.75 hrs
multiply equation by the least common multiple 240, cncel the denominators:
15d + 16d = 240(7.75)
31d = 1860
d = 1860/31
d = 60 km one way
total dist = 120 km
:
Check this, find the actual time each way
60/16 = 3.75 hrs
60/15 = 4 hrs
-----------------
total time 7.75 hrs

Water is flowing into and out of a small reservoir. The total amount of water can be modeled by R, where R(t)=20-15sint^2/25 cubic feet, t is measured in hours and 0
9514 1404 393
Answer:
a) about -1.03 cubic feet per hour
b) R'(t) = -6/5t·cos(t^2/25); the rate of flow into the reservoir
c) 0.859 and 5.972 hours
d) 9.838 hours
Step-by-step explanation:
The rest of the problem statement is in the first attachment. See the second attachment for the graphing calculator input/output.
a) The average rate of change on the interval [0, 8] is ...
(R(8) -R(0))/(8 -0) ≈ -1.03004 . . . cubic feet per hour
__
b) The derivative can be found using the chain rule.
R'(t) = -15(2t/25)cos(t^2/25)
R'(t) = -6/5t·cos(t^2/25)
The derivative of the volume is the rate of change of volume, that is, the flow rate into the reservoir.
__
c) To find the time values when R' = 'average rate of change', we defined the constant a1 to be that average rate of change. The graphing calculator shows the curve R'(t)-a1, which has zeros at the times of interest. The times for which the instantaneous rate of change equals the average rate of change are t = 0.859 and t = 5.972 hours.
__
d) The time of interest is beyond the domain of the function. We cannot use the given function to determine the time of interest.
However, if we extend the domain to include the time of interest, we find it is t = 9.838 hours.

Alyssa is helping to set up drinks and snacks for a luncheon.
Alyssa has 4.5 liters of lemonade to pour into pitchers. Each pitcher holds 0.9 liter of lemonade. If Alyssa pours an equal amount of lemonade into each pitcher, how many pitchers does she fill?
Alyssa drew the model below to show how many pitchers she fills.
The grids represent the amount of lemonade that Alyssa has. The lines represent Alyssa's division.
Answer in at least 2 complete sentences.
Is Alyssa's model correct?
Explain how do you know?
Answer:
Haha this isn't college Alyssa fills 5 pitchers. 4.5 divided by the liters of lemonade(0.9) equals 5 pitchers because 9x5=45 so, 4.5 liters of lemonade divided by 0.9 liters equals 5 pitchers.

A mouse eats 30 pieces of cheese in 10 minutes. How many pieces of cheese does she eat in 12 minutes?
Answer:
36 pieces of cheese in 12 minutes
Step-by-step explanation:
So we will divide the amount of cheese over the amount of time to get the amount of cheese eaten in one minute.
30/10 = 3
So the mouse eats 3 pieces of cheese each minute. So if the mouse ate 30 pieces of cheese in 10 minutes it will eat 36 pieces of cheese in 12 minutes
She will eat 36 pieces of cheese in 12 minutes
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
We are given that mouse eats 30 pieces of cheese in 10 minutes.
Therefore, we will divide the amount of cheese over the amount of time to get the amount of cheese eaten in one minute.
30/10 = 3
So, the mouse eats 3 pieces of cheese each minute.
Hence, if the mouse ate 30 pieces of cheese in 10 minutes then it will eat 36 pieces of cheese in 12 minutes.
