The ratio 11:4 means that the total number of spaces is a multiple of 15 parts, this multiple is what value is assigned to each part.
450/15=30 so each part is equal to 30 spaces
Full sized car spaces are 11*30=330 spaces
Compact car spaces are 4*30=120 spaces.
The value that should be used when one wants to determine the the amount of beach remaining after each is the common ration. This is because the the common ratio gives the percentage decrease or increase in value proportional to the original value. In our case the common ratio that should not miss in the model is 1.1%~ 0.011.
Answer is: the common ratio is 1.1%
First, 45 is the total number of students. So you have to add the ratio: 2+3=5. Since you are finding the number of sixth graders, you need to use the ratio 2.
Sixth graders : All = x : 45
2 : 5 = x : 45
You could change this to fractions and solve it.
2/5 = x/45
x = 18
So there are 18 sixth graders.
Answer:
x-intercept is 10. It means when you buy 10 cups of coffee you run out of money
Step-by-step explanation:
The x-intercept happens when y = 0
so
0 = 20 - 2x
solving for x we get
2x = 20
x = 10
so when you buy 10 cups of coffee you run out of money
