Answer:
7 out of 15 chance of selecting a pink or purple balloon
Step-by-step explanation:
just add the total of the two types of balloons and since there is 15 balloons in all the answer would be 7/15
Alright! To simply means to just put it as simple as it can be while still meaning the same thing. So, in this question you're simplifying:
![\frac{6xy^{6}z^{2} }{2y^{2}z^{8}}](https://tex.z-dn.net/?f=%20%5Cfrac%7B6xy%5E%7B6%7Dz%5E%7B2%7D%20%7D%7B2y%5E%7B2%7Dz%5E%7B8%7D%7D%20)
First, you divide the whole numbers:
![\frac{6xy^{6}z^{2} }{2y^{2}z^{8}}](https://tex.z-dn.net/?f=%20%5Cfrac%7B6xy%5E%7B6%7Dz%5E%7B2%7D%20%7D%7B2y%5E%7B2%7Dz%5E%7B8%7D%7D%20)
→
![\frac{3xy^{6}z^{2} }{y^{2}z^{8}}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3xy%5E%7B6%7Dz%5E%7B2%7D%20%7D%7By%5E%7B2%7Dz%5E%7B8%7D%7D%20)
All you have to do now is cancel out the powers with their corresponding base. So you'll get the following:
Answer:
18 ft
Step-by-step explanation:
Area = b x h / 2
Height = 9ft
Base = 4 ft
9 x 4 = 36
/ 2 = 18 Divide by 2
a. -8/3 miles below sea level.
Sasha started at sea level and has hiked down to the fourth rest station.
Now sea level is 0.
Sasha takes a break at the rest stations every 2/3 of a mile.
This means she is down to 4 rest points means 4 times 2/3
This becomes =
But the answer will be in negative as she is below 0.
So, correct answer is: a. -8/3 miles below sea level.
Other way,
sea level is 0.....so if u go below sea level, u will end up with a negative number...and since she is hiking down, ur answer will be negative. The is a station every 2/3 mile....and if she passed 4 of them....
-2/3 * 4 = - 8/3 <=== her elevation....another answer could have been - 2 2/3, but that is not there
5x - 20 = 12
5x = 32
x = 32/5
x = 6 2/5 or 6.4
