Given: m∠AEB = 45°
∠AEC is a right angle.
Prove: Ray E B bisects ∠AEC.
3 lines extend from point E. A horizontal line extends to the left to point A and a vertical line extends up to point C. Another line extends halfway between the other 2 lines to point B. Lines A E and E C form a right angle.
Proof:
We are given that m∠AEB = 45° and ∠AEC is a right angle. The measure of ∠AEC is 90° by the definition of a right angle. Applying the ______________
gives m∠AEB + m∠BEC = m∠AEC. Applying the substitution property gives 45° + m∠BEC = 90°. The subtraction property can be used to find m∠BEC = 45°, so ∠BEC ≅ ∠AEB because they have the same measure. Since Ray E B divides ∠AEC into two congruent angles, it is the angle bisector.

Answer:
The first term should be positive
She did not distribute the -4 properly
She added [tex]\frac{2}{7}[/tex] to negative -4 instead of multiplying
Step-by-step explanation:
In order to tell where she is wrong we should solve the question our selves. we are going to get the following......
[tex]-4(-3x + \frac{2}{7})= -4(-3x) + (-4)(\frac{2}{7} )= 12x - \frac{8}{7}[/tex]
So now we see that the three things she did wrong are.
The first term should be positive
She did not distribute the -4 properly
She added [tex]\frac{2}{7}[/tex] to negative -4 instead of multiplying
Hope this helps :)
Answer:
1, 4
Step-by-step explanation:
1. the product of two negatives are positive and they didn't do that, so yes.
2. the second term should NOT be positive, so they are correct on that.
3. they distributed the -4 correctly but added wrong, so they are correct on that.
4. -4+2/7=3 5/7 2/6(-4)=-4/3. They added instead of multiplying, so they are wrong.
5. they did simplify completely. they just did it wrong.

A local movie theater sells two bag sizes of popcorn. Both bags are in the shape of a rectangular prism. Bag A measures 4" long, 3.5" wide and 6" tall. Bag B holds twice as much popcorn as Bag A. If Bag B is 8" long and 3" wide, how tall is Bag B?
Answer:
the height of bag b is 7
Step-by-step explanation:
first, find the volume of bag a.
volume formula:
length * width * height = volume
length = 4
width = 3.5
height = 6
substitute the values into the formula
4 * 3.5 * 6 = volume
84 = volume
the volume of bag A is 84
next, find the height of bag b
volume formula:
length * width * height.
length = 8
width = 3
volume = 168 (84 * 2)
8 * 3 * h = 168
24h = 168
24h/24 = 168/24
h = 168/24
h = 7
the height of bag B is 7

What is the final amount if 1102 is increased by 2% followed by a further 1% increase?
Answer:
the final amount is 1,135
Step-by-step explanation:
The computation of the final amount is shown below:
= Amount × (1 + increased percentage)
= 1102 × (1 + 0.02)
= 1102 × 1.02
= 1124.04
Now the additional one percent increase is
= 1,124.04 × 1.01
= 1,135
Hence, the final amount is 1,135
The same is to be considered

Find the value of Y, 14 points
Answer:should be 125°
Step-by-step explanationz, y, and x make a 180° line. 52+3=55 and subtracting that from the total 180°gives you 125
Answer:
y = 8
Step-by-step explanation:
1. subtract 52° from 180° to get the value of the obtuse angle
2. that leaves you with 128° and now you subtract from 180° again bc the angles of a triangle always add up to 180° and so you have 52° now
3. the two angles you dont have add up to 52° and from here you write the equation 3y + 4y - 4 = 52
4. combine like terms to simplify the equation so you have 7y - 4 = 52.
5. add 4 to both sides so you get 7y = 56 nd then divide both sides by 7 leaving you with y = 8

At a party there were 20 more women than men. The men paid Rs 30 each, the women Rs 20 each, and the total receipts 2600. How many men and women were there in the party?
Answer: Number of Men = 44;
Number of Women = 64
Step-by-step explanation:
Let the number of men be x
At a party there were 20 more women than men. This means the number of women = x + 20
Since the men paid Rs 30 each, the women Rs 20 each, and the total receipts 2600. This will be represented in an equation as:
(30 × x) + [20 × (x + 20)] = 2600
30x + 20x + 400 = 2600
30x + 20x = 2600 - 400
50x = 2200
x = 2200/50
x = 44
The number of men = 44
Number of women = 44 + 20 = 64

Answer:
1
Step-by-step explanation:
Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, we write 5.6 x 10-9. So, how does this work?
We can think of 5.6 x 10-9 as the product of two numbers: 5.6 (the digit term) and 10-9 (the exponential term).
Here are some examples of scientific notation
