It’s c sorry if i’m wrong!
Answer:
n = 10
Step-by-step explanation:
given m varies directly as n then the equation relating them is
m = kn ← k is the constant of variation
to find k use the condition m = 6 when n = 5
6 = 5k ( divide both sides by 5 )
k =
= 1.2
m = 1.2n ← equation of variation
when m = 12 , then
12 = 1.2n ( divide both sides by 1.2 )
10 = n
Answer:
The variable X represents:
X = the number of books
The real world situation can be:
1.) Jennie reads books. She reads each books for
2.) Jennie wants to read book at least 5 books today.
Write an inequality that models the minimum number of books that Jennie needs to read.
The inequality for this situation is:
![2x \: \geqslant \: 5](https://tex.z-dn.net/?f=2x%20%5C%3A%20%20%5Cgeqslant%20%20%5C%3A%205)
Answer:
The integer representing the change is -43,200 gallons
Step-by-step explanation:
Here, we want to get the integer that represents the change in the number of gallons drained from the reservoir each week
Total number of hours per week would be 2 * 3 = 6 hours ;
6 hours is same as 6 * 60 = 3600 minutes
in a minute 12 gallons are drained
In 3600 minutes, the number of gallons drained would be;
3600 * 12 = 43,200 gallons are drained
When dealing with fractions, take the whole as 1.
in this case, the whole class is 1;
fraction of votes for Andrew: 1-1/2 -1/4 - 1/5
these fractions have different denominators (bottom), to continue, you have to make the denominators the same;
to do that, I usually count by the largest one. In this case, it is a 5. 5 is not divisible by 2 or 4, so I move on to 10. 10 is still not divisible by 2 and 4, so try 15, then 20.
20 works, so make all the denominators to 20. Remember 1 is 20/20:
20/20- 10/20 -5/20 -4/20 =1/20
so the fraction of votes Andrew got was 1/20.
For answer b, the whole is no longer 1. the whole is now 100.
1/2 of 100=50 for Amy
1/4 of 100=25 for Sophie
1/5 of 100=20 for Ryan
1/20 of 100=5 for Andrew
Notice the numbers add up to be exactly 100
