Which graph shows a line with a slope 3/2?
Answer:
C I think, im not sure but sorry if im wrong
Step-by-step explanation:
Answer:
Graph B.Step-by-step explanation:
Graph A. is too low and graph C. is too steep.
Also we know that 3/2 is equal to 1.5. This means that it will be a little more than y = x. So if we look at point (2,2), the line is not at that point, but the line is a little higher.
An extended graphs can be seen below

How many numbers are reciprocals of themselves?
Answer:
2
Explanation:
In short terms, there are two numbers that are reciprocals of themselves, 1 and -1. According to euler's identity, e^(-i*2*pi) is a reciprocal of itself, but I believe that is beyond the scope of this question.

Of those who like to fish, what percent are ages 13-18?
Answer:
B.) 42.9
Step-by-step explanation:
The percent that we are trying to find out is 12/28
I know this because if you add the 12 and 16 which is the total amount of people given then it leaves us with an amount of 28 people. Since we are trying to find the percent of the number of people who like fish we have to divide the total by 12 (the number of people who like fish)
Anyways 12 divided by 28 = 42.857etc.
If we simplify this then that gives us our answer of B.) 42.9

Please help me with my homework! Its past due and I am having trouble on it :/
Answer:
the first one is 57
the second one is 60
3rd one is 13
4th one is 9
Step-by-step explanation:
hope this helps :) have a nice day !!
**please let me know if this was wrong**
Answer:
1) In the second step, it was supposed to multiply 9 and 2 and 36 by 3 instead of adding 9 and 3 to each other because multiplication and division comes before adding, according to pemdas.
2) In the second step, they were supposed to multiply 6 and 4 instead of subtracting 27 and 6 because multiplication comes before subtraction, according to pemdas.
3)
(43 - 20) - 2 · 5
43 - 20 = 23
23 - 2 · 5
2 · 5 = 10
23 - 10 =
13
4) 81 ÷ (13 - 4)
13 - 4 = 9
81 ÷ 9
81 ÷ 9 =
9
5) 7 · 8 - 3 · 6 + 1
7 · 8 = 56
3 · 6 = 18
56 - 18 + 1
56 - 18 = 38
38 + 1 =
39
6)
7)
8)
Step-by-step explanation:
Section 1: Explain the error in each problem below.1) Pemdas says multiplication and division comes before adding, so you must solve the multiplication in the problem first before the addition.
2) Again, as pemdas says, multiplication comes first before subtraction, so you must solve the multiplication in the problem first before the sutraction.
Section 2: Simplify the following expressions.3) (43 - 20) - 2 · 5
Pemdas says to solve the parenthesis first.
43 - 20 = 2323 - 2 · 5Now multiplication comes next (because there's no exponents).
2 · 5 = 1023 - 10Now subtraction.
23 - 10 = 134) 81 ÷ (13 - 4)
Pemdas says to solve the parenthesis first.
13 - 4 = 981 ÷ 9Now division comes next.
81 ÷ 9 = 95) 7 · 8 - 3 · 6 + 1
Pemdas says to solve the multiplication first.
7 · 8 = 56 3 · 6 = 1856 - 18 + 1Now subtraction and addition.
56 - 18 = 3838 + 1 = 396)
Section 3: Insert grouping symbols to make the statements true.7)

Find the surface area of the rectangular prism.
First of all I wanna point out a minor mistake!
this is not a rectangular prism, the base of this picture is actually the side facing us and the back side. Making this a triangular prism.
We can start by finding the 2 triangles which are the bases.
Each triangle have area:10*24/2
Now because there are 2 same triangles we can get rid of the /2 and get the area of the triangles in the diagram is 10*24=240
We could do the other three sides 1 by 1, let's start with the side on the left of the shape. It has area 24*19=456 because the bottom is a rectangle so we could just use the 19.
Now we can do the side that is diagonal and on the right. It has area of 26*19=494.
Now just 1 more side the bottom, it has area of 10*19=190. Everything is in cm^2 as a unit because we are dealing with area.
Now we just need to add everything together.
240+456+494+190= 1380
Hope it helps! any questions about my answer please just leave in the comment I will get to it when I have time.
Answer:
your answer is 1380
Step-by-step explanation:
240+456+494+190= 1380
