(a) 1/3 hour plus 1/2 hour is 5/6 hour. The LCD here is 6.
(b) That would be 7 times 5/6 hour, or 35/6 hours, or 5 5/6 hours.
(c) Convert 35/6 hours (from part b) into minutes:
35 hours 10 min 350 min
------------ * ----------------- = ------------- = 350 min
6 (1/6) hr 1
Answer:
40 bunches of roses
Step-by-step explanation:
If Chris collected $679.60 at $16.99 a bunch:
679.60/16.99
He sold 40 bunches
=40
We'll call this number
We have
⇒
Since
is divisible by 5, it is either 0 or 5
But it can't be 0, because then
would be 0
So
and
Now I'm assuming that the second and third digits are
adding to three times the last digit.
So
⇒
We have a number of options:
So the possibilities are:
1695
1785
1875
1965
(If there were another detail we could narrow down the choices further, but otherwise we have all these options.)
Answer:
1. 1/36
2. 9/64
Step-by-step explanation:
First Question:
1. First thing I look for is how many spots are there and how many of them are for each color: both green and orange have 1 spot each out of six spots.
2. The chances of landing on each one is 1/6.
3. Now that they have to land back to back, I multiply the fractions by using the denominator which is 1 in 36 or 1/36.
Second Question:
1. Once again I see there are eight spots and blue has 3 of those.
2. I multiply the chance of it landing on blue on the first time, 3/8, by itself for the second time, 3/8.
3. You multiply the fractions and you get 9 in 64 or 9/64.
