For questions 2 and 3 plot the points in the coordinate plane. Then determine whether AB and CD are congruent. Explain your answ
max2010maxim [7]

Answer:

  2. congruent

  3. congruent

Step-by-step explanation:

Segments will be congruent if their lengths are the same. Their lengths will be the same if the sum of squares of the x- and y-differences of their endpoint coordinates are the same.

2. B-A = (-4-(-4), 8-1) = (0, 7)

  D-C = (5-(-2), -5-(-5)) = (7, 0)

The total of 0² and 7² is the same as the total of 7² and 0², so these segments are congruent. (They are both of length 7.)

__

3. B-A = (2-4, 6-1) = (-2, 5)

  D-C = (-4-(-2), -3-2) = (-2, -5)

The sum of (-2)² and 5² is the same as the sum of (-2)² and (-5)², so these segments are congruent. (They both are of length √29.)

Joe drives 20 mi-in 1/2 h. how Long Will it take him to derive 50 mi?
tiny-mole [99]
An hour and 15 minutes.  Since Joe is driving 20 miles per 1/2 hour that means he is driving 40 miles every hour. We still have 10 miles left and since 20 divided by 2 is ten you would simply cut the time it takes him to drive 20 miles in half making 15 minutes. Then you add the time it takes to drive 40 miles and 10 miles and that's how you get an hour and 15 minutes. Hope this made sense!

holly drinks 2 2/5 litre of water each day. The water comes in 1 2/5 litre bottles. How many bottles does Holly drink in a week?
AlladinOne [14]

Answer:Holly drank 12 bottles in a week.

Step-by-step explanation:

First change the fraction 1 2/5 litre into a decimal, by doing this, we can know how many litres are there in 2/5.

So= 1 2/5

= 2 ÷5 = 0.4

= 1 + 0.4 = 1.4 liters

1.4 liters is the amount of water in a bottle.

Next, also change the fraction 2 2/5 litres into a decimal.

So=2 2/5

= 2÷5 = 0.4

= 2 + 0.4 = 2.4 liters

She drinks 2.4 liters a day.

To find how many bottles she drank in 1 week, we must multiply the amount of water she drinks in a day to the days in a week.

So= 1 week= 7 days

= 1 day= 2.4 liters

So= 2.4 × 7 = 16.8

She drinks 16.8 in a week.

To find how much bottles she drank in a week, we must divide the amount of liters she drank in one week to the amount of liters are there in a bottle.

So= 16.8 ÷ 1.4= 12 bottles

Holly drinks 12 bottles in a week.

I hope this helps! I'm sorry if it's wrong and complicated.
