Divide 22,500 by 30,000 and multiply by 100 as follows:
Answer:
20 comic books
Step-by-step explanation:
Let us first <u>set up a variable</u>, x, for the number of books that Zoe has. If Jared has 12 more comics than Zoe, he would have x+12 books.
Given that Zoe and Jared have a total of 28 comic books, let us write an <u>equation</u> and solve for x:
Now that we have a <u>simplified</u> version of the equation, let us solve for x by <u>isolating the variable</u> on the left side:
We now know that x=8, and also that Jared has x+12 books. To find the number of comic books Jared has, let us <u>add</u> 12 to x:
Therefore, Jared has 20 comic books.

Answer:
The second term:
c(2) = 30
Step-by-step explanation:
c(n) = c(n - 1) + 10
c(1) =20
c(2) = c(1) + 10 = 20 + 10 = 30
Entering the numbers into a list lets a calculator do the work of this. The mode is 74, as that is the only value that appears more than once.
mean: 89
median: 87.5 . . . . . the average of the middle two numbers, 87, 88
mode: 74
range: 67–119, a difference of 52
variance: 243.4 . . . . . the square of the sd, or the difference of mean square and square of the mean
standard deviation: ≈ 15.6
Answer:
RT = 20
Step-by-step explanation:
Given that,
Point S lies on the line segment RT.
We have, ST = 3x-8, RT = 4x and RS = 4x-7
It is clear that, RT = RS+ST
Putting the values, we get :
4x = 4x-7 + 3x-8
Taking like terms together,
4x-4x-3x = -7-8
-3x = -15
x = 5
Put the value of x in RT = 4x.
So,
RT = 4(5)
RT = 20
Hence, length of RT = 20.
