Answer:
2*2*3*5
Step-by-step explanation:
We need to factor 60 until it is prime numbers
60 = 12*5 5 is prime 12 is not
=3*4 *5 3,5 prime 4 is not
= 3 *2*2 *5 2,3,5 are prime
Rearranging the order
=2*2*3*5
Answer:
Fraction of the original board left = ![\frac{2}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B15%7D)
Step-by-step explanation:
Let the length of the board is = l feet
Marty saws off
of a wooden board.
Length of the board left = l - ![(\frac{1}{5})l](https://tex.z-dn.net/?f=%28%5Cfrac%7B1%7D%7B5%7D%29l)
=
feet
He saws off
of the remaining board,
Board left = ![(\frac{4}{5})l-[(\frac{4}{5})l\times (\frac{3}{4})]](https://tex.z-dn.net/?f=%28%5Cfrac%7B4%7D%7B5%7D%29l-%5B%28%5Cfrac%7B4%7D%7B5%7D%29l%5Ctimes%20%28%5Cfrac%7B3%7D%7B4%7D%29%5D)
= ![\frac{4}{5}l-\frac{3}{5}l](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B5%7Dl-%5Cfrac%7B3%7D%7B5%7Dl)
=
feet
He finally saws off
rd of the remaining board.
Board left = ![\frac{1}{5}l-[\frac{1}{5}\times \frac{1}{3}]l](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7Dl-%5B%5Cfrac%7B1%7D%7B5%7D%5Ctimes%20%5Cfrac%7B1%7D%7B3%7D%5Dl)
= ![(\frac{1}{5}-\frac{1}{15})l](https://tex.z-dn.net/?f=%28%5Cfrac%7B1%7D%7B5%7D-%5Cfrac%7B1%7D%7B15%7D%29l)
=
feet
Fraction of the original board left = ![\frac{\frac{2}{15}l}{l}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B2%7D%7B15%7Dl%7D%7Bl%7D)
= ![\frac{2}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B15%7D)
Answer:
11
Step-by-step explanation:
61- 6= 55 55÷5= 11 dollara for each cd
<span>255 + 10m >= 650
10m >= 650 - 255
10m >= 395
m >= 395/10
m >= 39.5</span>
