answer:
8 pennies,16 dimes,13 nickels,13 quarters
Step-by-step explanation:
total number of coins = 50
16% are pennies
16% of 50
16/100 x 50=(16x50)/100=800/100=8
Pennies = 8
32% are dimes
32% of 50
32/100 x 50=(32x50)/100=1600/100=16
Dimes = 16
5 more nickels than pennies
Pennies = 8
nickels = 8 + 5 = 13
nickels = 13
8+16+13=37
50 - 37 = 13
13 quarters
pennies = 8, dimes = 16, nickels = 13, quarters = 13
Answer:
The answer is 12.
Step-by-step explanation:
You would multiply each of them by 12 to get rid of all of the fractions.
This is because 12 is the least common multiple of the denominators. You can find that by lining up their multiples and looking for the one that is the smallest that they have in common.
3: 3, 6, 9. 12. 15
4: 4. 8. 12. 16, 20
6: 6. 12. 18. 24. 30
Answer:
12,000.
Step-by-step explanation:
Let x be the number of people that were enrolled last year.
We have been given that enrollment at ELAC decreased by 5%, or 600 people, the year. We are asked to find the number of people that were enrolled last year.
We can set as equation such that 5% of x equals 600.
![\frac{5}{100}\cdot x=600](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B100%7D%5Ccdot%20x%3D600)
![0.05x=600](https://tex.z-dn.net/?f=0.05x%3D600)
![\frac{0.05x}{0.05}=\frac{600}{0.05}](https://tex.z-dn.net/?f=%5Cfrac%7B0.05x%7D%7B0.05%7D%3D%5Cfrac%7B600%7D%7B0.05%7D)
![x=12,000](https://tex.z-dn.net/?f=x%3D12%2C000)
Therefore, 12,000 people were enrolled last year.
