Melanie volunteers on the weekend at the Central Library. As a school project, she decides to record how many people visit the library, and where they go. On Saturday, 467 people went to The Youth Wing, 433 people went to Social Issues, and 342 went to Fiction and Literature.On Sunday, the library had 1500 total visitors. Based on what Melanie had recorded on Saturday, about how many people should be expected to go to Fiction and Literature? Round your answer to the nearest whole number.
Answer:
413 people should be expected to go to Fiction and Literature
Step-by-step explanation:
Proportion of people who went to Fictions and Literature on Saturday:
342 out of 467 + 433 + 343 = 1243
The proportion is:
342/1243 = 0.275
On Sunday:
Based on Saturday, so 0.275 out of 1500(number of visitors on Sunday).
0.275*1500 = 412.5
Rounding to the nearest whole number:
413 people should be expected to go to Fiction and Literature

Answer:
B
Step-by-step explanation:
its 60°
thank me later
Answer:
B
Step-by-step explanation:
Triangles have angle totals adding to 180. You already have 120 so the other must be 60.
Suppose that A, B, C, D, and E are matrices with the following sizes:
A B C D E
(4x 1) (4 x 1) (1 x 2) (2 x 1) (1 x 4)
Determine whether the matrix expression E (3B + A) is defined. Matrix is defined Enter the size of the resulting matrix (enter 'NA in each box if undefined).
E (3B + A) is a 3 X 3.
Answer:
The expression E (3B + A) is defined. The size of the resulting matrix is (1 x 1).
Step-by-step explanation:
Let's consider the following operations between matrices.
E (3B + A)
B is a matrix of (4 x 1), that is, it has 4 rows and 1 column. Let F = 3B. This is the product of a scalar by a matrix, which results in a matrix of the same size as the original. Then, F is a matrix of (4 x 1).
Now, let's consider the sum F + A, which we well call G. We can sum F and A because they are of the same size and we will get G, a matrix of the same size, (4 x 1).
Finally, we have the product E . G. We can multiply 2 matrices of sizes (m x k) and (k x n), that is, the number of columns of the first matrix must be equal to the number of rows of the second matrix, and the resulting matrix has a size (m x n). This is the case because E is (1 x 4) and G is (4 x 1), and the resulting matrix will be (1 x 1).

The sections on a spinner are numbered from 1 through 8. If the probability of landing on a given section is the same for all the sections, what is the probability of spinning a number less than 3 or greater than 5 in a single spin?
Answer:
5/8
Step-by-step explanation:
There are two numbers from one to eight that are less than three (1 and 2). So 2/8 of the numbered sections are less than three.
There are three numbers from one to eight that are greater than five (6, 7, and 8). So 3/8 of the numbered sections are greater than five
Probability of getting a number less than three: 2/8
Probability of getting a number greater than five: 3/8
Probability of getting either in a single spin = 2/8 + 3/8 = 5/8

amount, sales tax and final cost of the tent?
the discount price was 29.2
step by step 146 minus 20% = 116.8 116.8 + 4% =121.472 the sales tax added 4.672$ to the total amount and the discount price removed 29.2 of the required pay
What does it mean to restate using scientific notion
Restating into scientific notation means, making a super big or a super small number, more understandable to read. For example,
5,972,000,000,000,000,000,000,000.0012 is a big number. I don't think you even tried to read that. There is a solution to this problem. This is the exact number but in scientific notation. 5.972 × 10^24. Isn't that easier to read?

Solve 5(2x + 3) = 20
Answer:
Therfore, the value of x is 1/2.
Step-by-step explanation:
5(2x + 3) = 20
10x + 15 = 20
10x = 20-15
10x = 5
x = 5/10
x = 1/2
Answer:
0.5
Step-by-step explanation:
5(2x + 3) =20
10x + 15 = 20
10x = 20-15
10x =5
x= 1/2

Can anybody give me the answers to these questions
Answer:
830 cents
5n + p
Step-by-step explanation:
Given that :
Number of nickels = 140
Number of pennies = 130
Total coins :
140 nickels + 130 pennies
1 nickel = 5 cent
1 penny = 1 cent
Hence,
140(5) + 130(1)
700 + 130
= 830 cents in total
If :
number of nickels = n
Number of pennies = p
Tot coins :
5n + 1p
5n + p

help with the Measure of a triangle’s side
Answer:
x = 163.5
x = 1.2
Step-by-step explanation:
Recall: SOH CAH TOA
For the first triangle:
Reference angle = 73°
Opposite = x
Adjacent = 50
Apply TOA:
Tan 73° = Opp/Adj
Tan 73° = x/50
50*Tan 73° = x
163.542631 = x
x = 163.5 (nearest tenth)
For the first triangle:
Reference angle = 4°
Opposite = x
Adjacent = 17
Apply TOA:
Tan 4° = Opp/Adj
Tan 4° = x/17
17*Tan 4° = x
1.1887558 = x
x = 1.2 (nearest tenth)
