In Step 1, I used my straightedge to draw my first line segment. Using the straightedge is key to making a perfect line, so no mistakes will result from a messy line.
In Step 2, I named my two points. It is important to name your points so you do not get confused.
In Step 3, I used my compass to measure the exact width of line AB. I did this because I know later I will need to to create the copy line.
In Step 4, I drew a ray. I know the ray doesn't have to be perfect yet so I eyeballed the length. I named the starting point C.
In Step 5, I placed the compass that had the measurements from the original line on the new ray. I did this because I need to find the new point for the new line segment.
In Step 6, I used the compass to draw an arc. I drew the arc to show where the new point should go on the ray.
<span>Lastly, in Step 7 I put the new point on the line segment and named it D. </span>

Alicia uses 3/4 gallon of paint to paint her room. Becca uses for 4/5 gallon more than Alicia to paint her room. How many gallon
Maurinko [17]

Answer:

23/10 gallons

Step-by-step explanation:

Alicia uses 3/4 gallon of paint to paint her room.

Alicia use = 3/4 gallon of paint

Becca uses for 4/5 gallon more than Alicia to paint her room.

Becca uses = Alicia (3/4 gallons ) + 4/5

Becca uses = \frac{3}{4} + \frac{4}{5}

Total paint used together = Aliccia used + Becca used

\frac{3}{4}+\frac{3}{4} + \frac{4}{5}

Add like fractions 3/4 + 3/4 becomes 6/4

\frac{6}{4} + \frac{4}{5}

Make the denominators same

\frac{6*5}{4*5} + \frac{4*4}{5*4}

\frac{30}{20} + \frac{16}{20}

\frac{46}{20}

Divide top and bottom by 2

\frac{23}{10} gallons

You weigh six packages and find the weights to be 20, 12, 52, 16, 48, and 44 ounces. If you include a package that weighs 60 oun
kvv77 [185]

Answer:

median

Step-by-step explanation:

The first step is to sort the numbers from largest to smallest (you could go the other way as well).

60 52 48 44 20 16 12

The median is the middle number 44 in this case. The median has 3 numbers on its left and 3 on its right (in this case). 44 has 60 52 48 or its left and 20 16 and 12 on its right.

The mean is the average. We'll call it the new average

The mean is 60 + 52 + 48 + 44 + 20 + 16 + 12 = 252

The new mean is 252 / 7 = 36

=====================

The old median is the average between the middle 2 numbers (before you added 60 you had 6 numbers)

52 + 48 + 44 + 20 + 16 + 12 = the average of 44 + 20 which 64/2 = 32

The old mean was (52 + 48 + 44 + 20 + 16 + 12)/6 = 32.

=======================

The median increased from 44 to 32 = 12

The mean went from 32 to 36 which is 4

Answer: the median increased more
