Answer:
C) 2/9
Step-by-step explanation:
There are 9 total marbles in the bag and 2 are yellow.
Probability = (number of desired outcomes)/(number of total outcomes)
Here the desired outcome is pulling a yellow marble, there are 2 ways we can do that since there are 2 yellow marbles.
The total number of outcomes is 9 since there are 9 total marbles in the bag
Our fraction is 2/9
Step-by-step explanation:
according to the table, the rate of change of the water level =
(40-50)/(2-0)
= -10/2
= -5 ft/hr
Answer:
![\frac{7}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B10%7D)
Step-by-step explanation:
![2\frac{4}{5}=\frac{10}{5}+\frac{4}{5}=\frac{14}{5}\\\frac{14}{5}(\frac{1}{4})=\frac{14}{20}\\\frac{14}{20}=\frac{7}{10}](https://tex.z-dn.net/?f=2%5Cfrac%7B4%7D%7B5%7D%3D%5Cfrac%7B10%7D%7B5%7D%2B%5Cfrac%7B4%7D%7B5%7D%3D%5Cfrac%7B14%7D%7B5%7D%5C%5C%5Cfrac%7B14%7D%7B5%7D%28%5Cfrac%7B1%7D%7B4%7D%29%3D%5Cfrac%7B14%7D%7B20%7D%5C%5C%5Cfrac%7B14%7D%7B20%7D%3D%5Cfrac%7B7%7D%7B10%7D)
Answer:
![scale](https://tex.z-dn.net/?f=scale)
Step-by-step explanation:
To figure this out, we must use the scale of the map as a unit.
So we first figure out how many meters are for each centimeter on the map.
" Two fields at a state park are fields are 8 centimeters ap(?)ta state park are 1,000 meters from each other."
<u>Set up the ratio:</u>
![\frac{1000}{8} = \frac{x}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B1000%7D%7B8%7D%20%20%3D%20%5Cfrac%7Bx%7D%7B1%7D)
<u>Cross multiply:</u>
= ![1000](https://tex.z-dn.net/?f=1000)
<u>Meaning:</u>
![x = \frac{1000}{8}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B1000%7D%7B8%7D)
1000/8
==> 125
x = 125
Meaning that for every centimeter there is 125 meters
1cm = 125m
Answer:
x - 3
Step-by-step explanation:
(8x + 6) - (7x + 9)
8x - 7x = 1x = x
6 - 9 = -3
x - 3
