Answer:
[tex]4\frac{7}{32}[/tex]
Step-by-step explanation:
Given the mixed numbers:
[tex]1\frac{1}{4}[/tex],[tex]1\frac{1}{2}[/tex],[tex]2\frac{1}{4}[/tex]
First, we need to convert them into improper fractions of the denominator of 4.
1 1/4 = 5/4
1 2/4 = 6/4
2 1/4 = 9/4
So we multiply 1 1/4 x 1 2/4 x 2 1/4 which gets us 4 7/32

The salaries of 4 players on a professional basketball team average $200,000 per year. If a fifth player is hired for $400,000 per year, what will be the average salary for the 5 players? Answer with supporting work:
Answers
If salary average of 4 players is making $200,000/yr, what's the total payroll? It should be $200K x 4 or $800,000.
Now if you add in that 5th player at $400,000 what is the total payroll of all 5 players? It should be $800,000 + $400,000 = 1,200,000. From there you can find the average of the 5 players by dividing!

A long year end status report for work is 136 pages long. You need to print 19 copies for a meeting next week. How much is the paper going to cost for those reports? Paper is sold in reams (500 pages) for $3.80 each. Give your answer to the nearest cent, only for the paper you use.
Answers
Answer:
$19.60
Step-by-step explanation:
Given data
number of pages= 136 pages
number of copies = 19 copies
Hence 19 copies make a total of = 136*19
=2584 pages
hence if 500 pages cost $3.80
then 2584 pages will cost x
cross multiply
500x= 2584*3.8
500x=9819.2
Divide both sides by 500
x= 9819.2/500
x= 19.6384
x=$19.60
It will cost $19.60

A circular flower garden has a diameter of 16 ft. A square pond is placed in the center that measures 5 ft on each side. About how much area of the garden remains for the flower garden
Answers
Answer:
779.352 ft^2
Step-by-step explanation:
Given data
Diameter of circular garden= 16ft
Radius of garden= 16/2= 8ft
Length of side of square pond= 5ft
Area of circular garden= πr^2
A=3.142*16^2
A= 3.142*256
A=804.352 ft^2
Area of square pond
A= L^2
A= 5^2
A= 25ft
Hence the area that remains
=Area of circular garden- Area of square pond
=804.352- 25
= 779.352 ft^2
