Find The Area Of The Shaded Region. Help Pls

Answers

Answer 1

Answer:

1. 50 m

2. 80 cm

Step-by-step explanation:

1. There are 2 triangles, subtract the area of 1 of them from the other.

The triangle that needs to be subtracted: b = 20 m, h = 10 m

A = 1/2b * h = 1/2(20) * 10 = 10*10 = 100 m

The big triangle, the one that needs to be subtracted plus the one you need to find the area of: b = 20 cm, h = 15 cm, 1/2(20) * 15 = 10 * 15 = 150

150 - 100 = 50 c

2. Divide it into 3 parts:

1- 3*4 = 12

2. 7*(4 + 4) = 7*8 = 56

3. [(4 + 4) * (13 - 7 - 3)]/2 = (8*3)/2 = 24/2 = 12

12 + 56 + 12 = 80 cm

The independent variable would be the one that could stand alone. So which one makes more sense? The amount of trips depends on how many buckets there are or the amount of buckets depends on the amount of trips?

Since the amount of trips DEPENDS on the amount of buckets... the amount of trips is the dependent and the buckets is the independent. so since there are 2 buckets carried up to hill for 1 trip, the first row on the table should look like this

2 1 (2,1)

So how many buckets would be on the hill after the second trip?

Well there are 2 more and 2 + 2 is 4. 2 trips = 4 buckets. So the next row would look like this

4. 2. (4,2)

Then u just keep going. Hint: Independent variable is counting by twos and dependent variable is counting by one's.

Then you graph the ordered pairs.

Hope this helped :)

8. A number k is decreased by 8 and the results is multiplied by 8. This product is then divided by 2. What is the final results?

f. 8k -4
g. 4k -8

j. 8k -64

Answers

Probably H to be honest
h. 4K - 32
(K - 8)*8 = 8k - 64
(8k - 64)/2 = 4K - 32

Step-by-step explanation:

Perimeter is W+L=P. So add 16 and 11 and you get 27. There are 12 inches in a foot so all you would do is see how many times 12 goes into 27 (twice) and put the remainder as inches. So 12 feet and 3 inches. I hope this helped and I hope I'm right.

Answers

Answer:

the y-intercept is 7

Step-by-step explanation:

hope it helps. i just looked at the ordered pair and took the number that's on the y axis

Answer:

y=5x-3

Step-by-step explanation:

Slope intercept form is y=mx+b and you know the slope so you can get y=5x+b

Then you are given a point, (2, 7), so you can plug that into the equation to find the y-intercept

7=5(2)+b

Then you just solve for b

7=10+b

-10

-3=b

So the final equation is y=5x-3

Do the calculation below

6(18 + 14)

Answers

Answer:

Explained below...

Step-by-step explanation:

First, recognize the acronym PEMDAS, which stands for:

P - Parenthesis

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

So, as there are parenthesis, that will be your first step in the expression.

6(18 + 14) --> 6(32)

Now, you will find the next step in PEMDAS, which would be multiplication.

6 * 32 = 192.

So, your answer for the equation is 192.

Hope this helps! :)

6(18 + 14) = 192
