Hi!

First, let's find the LCD of the denominators. (5, 4, and 2)

2, 4, 6, 8, 10, 12, 14, 16, 18, 20
4, 8, 12, 16, 20
5, 10, 15, 20

Now we have to change all of the numerators to match the denominators. 

Since 5 goes into 20 four times..
2 x 4 = 8
8/20

Since 4 goes into 20 five times...
3 x 5 = 15
15/20

Since 2 goes into 20 ten times...
1 x 10 = 10
10/20

Our new fractions are..
8/20+15/20+10/20=?

Now just add the numerators.
33/20

If you want to simplify it to a mixed number, your answer is 1 13/20
If you want to keep it as a fraction, it's already in simplest form. So the answer is 33/20

Hope this helps! :)

Answer:

  m∠AEC = 139°

Step-by-step explanation:

To make the equations easier to write, let's say all measures are in degrees, and define ...

  p = m∠AEB = 11x -12

  q = m∠CED = m∠CEB = 4x +1

Then ...

  p + 2q = 180

  (11x -12) + 2(4x +1) = 180

  19x -10 = 180 . . . . . . . . . . . . collect terms

  19x = 190 . . . . . . . . add 10

  x = 10 . . . . . . . . . . . divide by 19

  p = 11x -12 = 110 -12 = 98

  q = 40 +1 = 41

The angle of interest is ...

  m∠AEC = p +q = 98 +41

  m∠AEC = 139 . . . . degrees

Answer:

Area=45

Step-by-step explanation:

Area=AC*BD/2=V12^2+(-9)^2*V6^2+8^2=(V144+81)*V36+64/2=V225*6/2=15*6/2=45

Imagina that the cook is using a potato-chopping machine instead of a knife, allowing him to chop a maximum of 120 potatoes inst
FrozenT [24]

The number of hamburgers he could cook is 14 if he chopped 100 potatoes with the machine option (B) is correct.

<h3>What is the graph of the best estimate?</h3>

A mathematical notion called the graph of the best estimate connects points spread throughout a graph.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have shown a graph in the picture that shows the number of hamburgers cooked versus the number of potatoes chopped.

As we can see in the graph,

Number of potatoes chopped = 80

number of hamburgers cooked = 30

Number of potatoes chopped = 90

number of hamburgers cooked = 20

Number of potatoes chopped = 95

number of hamburgers cooked = 10

Number of potatoes chopped = 100

number of hamburgers cooked = 14 (best estimate)

Thus, the number of hamburgers he could cook is 14 if he chopped 100 potatoes with the machine option (B) is correct.
