You earn $44.55 in 9 hours. Your friend earns $51.00 in 12 hours. How much do you AND your friend earn in 20 hours? HINT- You need to calculate how much you both make in 1 hour first! 1 point

Answers

Answer:

I earn $99. my friend earns $85. We both earn $184

Step-by-step explanation:

Steps

Find the amount earned per hour for each friend multiply the value gotten by 20 hours Add the amount

Amount i earn per hour = 44.55 / 9 = $4.95

Amount my friend earns = 51 /12 = $4.25

Amount earned in 20 hours

4.95 x 20 = 99

4.25 x 20 = 85

I think the question is asking for the median. If that’s not right, let me know in the comments, and I will help you more.

If we write these data points in order:

2, 4, 4, 5, 5, 6, 6, 6, 6, 7, 8, 9, 10

I start crossing off numbers from one end to the other to find of the middle data point. That’s what the median is.

Remove the first 6 data points and the last 6 data points, and you have your median. If the next median problem you have to solve has an even number of data points, your average the middle two.

How do I solve this?
-1/3+y=1

Answers

Answer:

y=-3

Step-by-step explanation:

.....................

Answer to equation:

y = 1 1/3

Step-by-step explanation:

for this problem we see that we are starting below 0 and going up to one, all we have to do is solve for the distance between the two numbers, as shown

(-1/3) + 1/3 = 0

0 + 1 = 1

now to simplify, we just add the total amount of change between the two numbers

1/3 + 1 = 1 1/3

NOTE: this can be done by just adding the absolute value of each number if one is a negative number and one is a positive number, wich is basically what i did

-1/3 = |1/3|

1 = |1|

|1/3| + |1| = |1 1/3| or total amount of change

but if you are working with two positive or two negative numbers, then subtract the lesser of the two absolute values as so

-2 + x = -5

-2 = |2|

-5 = |5|

|5| - |2| = |3|

3 = amount of change

3 = x

-2 + -3 = -5

Find the area of the hexagon. i will mark brainliest and pls explain.

Answers

Answer:

C. 150√3

Step-by-step explanation:

Radius of the inscribed circle is the apothem of the hexagon.

Apothem (a) and half of the side (s) make a 30-60-90 right triangle.

The ratio of the legs, as per property of 30-60-90 triangle:

s : a = 1 : √3 ⇒ s : 5√3 = 1 : √3 ⇒ s = 5

Half the side is s = 5 units, then side of the hexagon is 10 units.

The area of the hexagon:

A = 1/2Pa, P- perimeter, a- apothemA = 1/2(6*10)*(5√3) = 150√3
