<A = 72°
<B = 108°
Explanation :<A = <C
(5y - 3)° = (3y + 27)°
5y-3y = 27 + 3
2y = 30
y = 15
<A = (5y - 3)°
<A = (5 x 15) - 3
<A = 75 - 3
<A = 72°
<B + <A = 180°
<B + 72° = 180°
<B = 180° - 72°
<B = 108°

The midpoint of overline AB is M(0, - 7) . If coordinates of A are (- 2, - 6) , what are the coordinates of B?
Answers
Given:
The midpoint of overline AB is M(0, - 7) .
The coordinates of A are (- 2, - 6).
To find:
The coordinates of point B.
Solution:
Let the coordinates of point B are (a,b).
Midpoint formula:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
The midpoint of overline AB is M(0, - 7). Using the midpoint formula, we get
[tex]M=\left(\dfrac{-2+a}{2},\dfrac{-6+b}{2}\right)[/tex]
[tex](0,-7)=\left(\dfrac{-2+a}{2},\dfrac{-6+b}{2}\right)[/tex]
On comparing both sides, we get
[tex]\dfrac{-2+a}{2}=0[/tex]
[tex]-2+a=0[/tex]
[tex]a=2[/tex]
And,
[tex]\dfrac{-6+b}{2}=-7[/tex]
[tex]-6+b=-14[/tex]
[tex]b=-14+6[/tex]
[tex]b=-8[/tex]
Therefore, the coordinates of point B are (2,-8).

Which is a solution to the equation StartAbsoluteValue 10 minus 5 y EndAbsoluteValue = 20?
y = 2
y = 4
y = 6
y = 10
Answers
Answer:
x=the circumference of absolute end triangularitizeationing particle matter
Answer:
Answer is y=6 (option C).
Step-by-step explanation:
|10 - 5y| = 20
First equation is just as written for first solution:
10 - 5y = 20
Subtract 10 from both sides to eliminate the 10.
-5y = 10
divide both sides by -5 to eliminate the -5 and isolate the y.
y = -2
Distribute negative sign through equation for a second solution.
|10 - 5y| = 20
-(10 - 5y) = 20
-10 + 5y = 20
Add 10 to both sides to eliminate the 10.
5y = 30
divide both sides by 5 to eliminate the 5 and isolate the y.
y = 6
y = 6 is the only answer listed in the 4 options.
The Murphy family is on a road trip. On the first day, they traveled 30% of their total distance. On the second day, they traveled another 1 4of the total distance. What fraction of the total distance do they have left after
Answers
Answer:
5/12
Step-by-step explanation:
Total distance travelled = 30% + 1/4
To add these numbers, convert 30% to fraction
30% = 1/3
1/3 + 1/4 = 7/12
Remaining distance = 1 - 7/12 = 5/12

How do I find the missing side length for 30 - 60 - 90 method as a radical in simplest form?
Answers
Answer:
Step-by-step explanation:
see the image below
Step-by-step explanation:
The side that is adjacent to 60 degree and 90 degree is the shortest side.
If u know the hypoutnese you can divide it by 2 to find the shortest side. for example if the hypotenuse is 10 then the shortest side is 5
If you know the other leg you can simply just remove the entire radical and just keep the whole number to find the length of the shortest side.
The side that his the adjacent to the 30 degree and 90 degree angle is the second longest side of the triangle.
If u know the shortest side, just multiply the radical
[tex] \sqrt{3} [/tex]
to the whole number.
If you know the hypotunese, divide the hypotenuse by 2 and then multiply the radical to find the length of the second shortest side
Finally, the hypotunese is the largest side. It is the slanted side length that is adjacent to the 30 and 60 triangle.
If you know the shortest side, just multiply the side length by 2 to get the hypotenuse.
If you know the other leg, remove the radical and keep the who the number and multiply the whole number by 2.
E.x if the second longest side length is
[tex]5 \sqrt{3} [/tex]
Remove the radical so it becomes
[tex]5[/tex]
then multiply it by two to find the hypotunese.
[tex]5 \times 2 = 10[/tex]

Answer:
first question: decrease - second question: 34
Step-by-step explanation:
first question: to find the mean, you need to add all of the numbers together and divide the sum of those by the amount of numbers you added together. in this question, it would be
73+79+96+84=332 -> 332/4=83 is the mean for the 1st set of numbers
(1) (2) (3) (4)
the question asks what happens after the next test score is added in, for this, you will do the same steps as before except you add in the 80 for her fifth test and then divide by 5 instead of 4, because you have another number being added.
73+79+96+84+80=412 -> 412/5=82.4 is the mean for the 2nd set of numbers
the second set of numbers, after the fifth test score is added in, is lower than the first set of numbers. therefore, the mean decreases
second question: same concept, except on a dot plot. a dot above a number means that there is one of those numbers that should be counted. this means since there are 2 dots above the 30, there are 2 30s being added to the rest of the numbers. in this dot plot, the numbers being added are
30+30+32+32+34+38+38+38=272 -> 272/8=34 is the mean

Caiden earned $475 from mowing lawns last summer. He deposited this money in an account that pays an interest rate of 3.8% compounded annually. What will be his balance after 2 years?
Answers
Answer:

Step-by-step explanation:
Given data
P=$475
R=3.8%
T= 2 years
Compound interest
A=P(1+r)^t
substitute
A=475(1+0.038)^2
A=475(1.038)^2
A=475*1.077
A=511.575
Hence the final amount is $511.575

3 is a prime number so to split it up you would put 3y in one parentheses and y in the other. at this point it will look like this
(3y )(y )
now, you need to figure out what your signs would be (+ or -) because the second sign in the equation is a negative, your signs would be one + and one - you can decide where to put them until you figure out your two factors. in this case you need to figure out 2 numbers that multiply to 5 and add up to 2. you might think this is impossible, but since the 3 is there, one of those numbers can be multiplied by three. this is your answer:
(3y-1)(y+2)

We're going to let x represent the length of the longest side. The perimeter is

4x -18 = 25
4x = 43
x = 43/4 = 10 3/4
Then x-6 = 4 3/4.
