V = s/t
now, t is equal for both cases so we write these 2 equations:
440/(Vp+Vw) = t
and
340/(Vp-Vw) = t
Now again, since t is equal for both cases we can make these 2 equations equal to eachother.
440/(Vp+25) = 340/(Vp-25)
(Vp - 25)*44=34*(Vp+25)
44Vp - 1100 = 34Vp + 850
10Vp = 1950
Vp = 195
Answer is 195mph
This relation is a function because each input has only one output
Answer:
4 - 5 = 40 books about travel. 80 are school stories.
6-7 = 30 are about nature. 48
8 =24
9 = 18
10 = 2001
Step-by-step explanation:
<h3>4,5,6,7,8</h3>
1/10 = 24 = sport
1/8 = 30 =nature
1/6= 40 =travel
1/5 = 48 = adventure
1/3 = 80 = schools stories
To get that you just have to read the question, find the fractions, percentages etc.
I put them all into fractions and divide 240 by the denominator.
<h3>9</h3>
For question 9, you just have to add all of the amounts of books together and take that away from the total amount. In this case it is 240 - 222 = 18
<h3>10</h3>
You just have to write it out.
Answer:
ok so the answer is x>−99/4
Step-by-step explanation:
Let's solve your inequality step-by-step.
