complementary
corresponding
supplementary
vertical

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:

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.

3) (43 - 20) - 2 · 5

Pemdas says to solve the parenthesis first.

Now multiplication comes next (because there's no exponents).

Now subtraction.

4) 81 ÷ (13 - 4)

Pemdas says to solve the parenthesis first.

Now division comes next.

5) 7 · 8 - 3 · 6 + 1

Pemdas says to solve the multiplication first.

Now subtraction and addition.

Answer: when it’s a less than or greater than

Step-by-step explanation:

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

Step-by-step explanation:

NQ is perpendicular to OM

Answer:

For the first one your first point is going to be on (0, -8) and will be a continuous horizontal line.

For the second equation the first point will be on (0, -12)

you want to go down two points and go to the right once point so (1, -14), (2,-16), (3,-18)

you also want to go up two points and to the left once so (-1, -10), (-2, -8), (-3, -6) and so on

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

Step-by-step explanation:

Answer:

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

Step-by-step explanation:

3x² + 22x + 35 = 0

(3x + 7)(x + 5) = 0

3x + 7 = 0
