Answer:
see attached
Step-by-step explanation:
A spreadsheet is a useful tool for keeping track of the numbers. A picture of one is attached.
We have assumed that the dollar amount for housing computed in the first part remains the same (though the percentage changes). If that is not the case, you'll have to recompute.
Likewise, we assume that the "5%" retirement amount remains 5% of the nominal salary, rather than 5% of the salary after the mandatory retirement deduction. Similarly, we assume dance lessons remain at their original amount, and were not reduced when the company began taking mandatory retirement.
Feel free to build your own spreadsheet and recompute as needed for any assumptions I got wrong, or for any additional scenarios.
Answer: 65 people completed graduate school.
Step-by-step explanation:
25% of 260 is 65.
That "3" is a measure of units halfway across the square. So, the total distance across the square is 6.
Since this is a square, and since, with squares, all sides are equal, the width of the square would also be 6.
To find the area, simply multiply the base by the height.
6*6=36
So, the answer is 36 square units.
Answer:
100 of the 20$ tickets, and 60 of the 35$ tickets
Step-by-step explanation:
20*x + 35*y = 4100
x + y = 160
That means x = 160 - y, put this into the first equation
20(160 - y) + 35y = 4100
3200 - 20y + 35y = 4100
15y + 3200 = 4100
15y = 900
y = 60
Put y = 60 into the second equation and
x + 60 = 160
x = 100
y = 60, x = 100
Double check that this works for both equations to make sure its right
20 * 100 + 35 * 60= 4100
2000 + 2100 = 4100 /Correct
100 + 60 = 160 /Correct
Answer:
dan - 42:7 / 6:1
mia - 48:6 / 8:1
Step-by-step explanation:
mia has the greater sleep to days ratio because she sleeps 8 hours a day, whereas, dan sleep 6 hours a day. as you can see, the ratios can be ordered from greatest to least making mia have the greater ratio.
hope this helps :3
