Answer:
x=50°
Angle at A=108°
Step-by-step explanation:
If the triangle ABC is isosceles,then <ABC=<ACB=65°
We can now use angle properties to find <BAC
<BAC+65+65=180°
<BAC=180°-130=50°
Since line AB and CD are parallel,line AC is a transversal line which means <BAC=<ACD=x=50°
Therefore x=50°
For the parallelogram,
opposite interior angles are equal so <BAD=<BCD and <ABC=<ADC
3x+3x+2x+2x=360°
10x=360°
x=360°/10=36°
The angle at a=3x=3×36°=108°

A computer salesman makes $10 per hour and 0.5% commission on what he sales. If he works for 40 hours this week, and he sales $4,500 of computers, how much will he make total?
Answers
Answer:
Total income earn = $422.5
Step-by-step explanation:
Given:
Earning per hour work = $10
Total hour = 40
Commission = 0.5% on sales
Total sales = $4,500
Find:
Total income earn
Computation:
Income from hour work = $10 x 40
Income from hour work = $400
Total commission = 0.5% x sales
Total commission = 0.5% x $4,500
Total commission = $22.5
Total income earn = $400 + $22.5
Total income earn = $422.5

A rectangular computer monitor is measured by the length and width of its display resolution. Three different monitors are described below. Monitor A has a display resolution of 640 pixels by 480 pixels. Monitor B has a display resolution of 800 pixels by 600 pixels. Monitor C has a display resolution of 1,280 pixels by 800 pixels. Which of the monitors are similar, based on their display resolution
Answers
Answer: Monitors A and B
Step-by-step explanation:
The similar monitors based on display resolution are those with similar ratios.
Take the ratios to their simplest forms to see which are similar.
Monitor A
= 640 : 480
= 16 : 12
= 4 : 3
Monitor B
= 800 : 600
= 8 : 6
= 4 : 3
Monitor C
= 1,280 : 800
= 32 : 20
= 8 : 5
Monitors A and B are similar as they have the same display ratio.

Maureen spends four times as long riding the train each day as riding the bus. If she spends 75 minutes on the bus and the train all together, how long did she spend riding the train
Answers
Answer:
60 minutes or 1 hour
Step-by-step explanation:
Set x as the amount of time she spends riding the bus
75 = time on bus + time on train
She spends 4 times as long on the train as on the bus so the time she spends on the train is 4x
75 = x + 4x
75 = 5x
x = 15 minutes on the bus
Since she spends 4 times as long on the train, we do 4 x 15 and we get 60 minutes which is 1 hour
one important point to remember is that just because a difference between two treatment groups is found to be statistically significant, it does not mean that the difference:
Answers
Researchers use a finding's Effect size to measure magnitude and reliability.
a difference in significance does not always make a significant difference.
One reason is the arbitrary nature of the p<0.05 cutoff. We could get two very similar results, with p=0.04 and p=0.06, and mistakenly say they’re clearly different from each other simply because they fall on opposite sides of the cutoff.
The second reason is that p values are not measures of effect size, so similar p values do not always mean similar effects. Two results with identical statistical significance can nonetheless contradict each other.
Effect size refers to the measure of the magnitude of the experiment's effect. In other words, effect size measures how important is the relationship between two variables. The larger the effect size, the stronger this relationship is. Moreover, when the effect size is large, you are more likely to be dealing with a relationship that has practical significance.

d. |−1|___________|—8|
C.
Answers
We can complete the given statements as follows-
a. 21 < 51
b. -5< |-9|
c. |5| = |-5|
d. |−1|< |-8|
Let us look at each statement one by one-
a. 21_51
here, we can clearly see that 21 is smaller than 51, so we use the < sign.
Thus, 21 < 51
b. -5_|-9|
here, on the right hand side we have a modulus sign. The modulus sign implies that we take only the absolute value.
|−9| = 9
Now, if we compare -5 and 9, 9 is clearly greater.
Hence, -5< |-9|
c. |5|__|-5|
here, |5| = 5
and |-5| = 5
Thus, |5| = |-5|
d. |−1|__|-8|
Here, |−1| = 1
and |—8| = 8
And 1 < 8,
thus, |−1|< |-8|

What is the equation for the line in slope-intercept form?
Answers
Let the points represented by the given points on a line .
We well know the equation of the line.
So equation of the line is,
y = mx+b.
Where m= slope of the line
b= y intercept.
Now, let the points lying on the line are
(0,-2) nad (3,-3).
We know that ,
Slope of the line 'm' = (y2-y1)/(x2-x1).
m=-2-(-3)/0-3
m=-2+3/0-3
m= 1/-3.
y intercept 'b' = (-2).
Then , equation of the line is
y = (-1/3)x-2

Mr. majors ordered six hot dogs and a bucket of popcorn at the concession stand. if the popcorn was $3.20 and the total was $18.20, what was the price of one hot dog?
Answers
Answer:
The price of one hotdog is $2.50
Step-by-step explanation:
You can first write this out as an equation to make it easier to solve.
Lets say that x= the price of a hot dog and y= the price of popcorn
The equation would be:
6x + y = 18.20
We know that y= 3.20 so we can subtract 3.20 from 18.20. That will leave us with 6x = 15
Then, we just have to divide both sides by 6 and our answer comes out as x = 2.50
Answer:
2.50
Step-by-step explanation:
18.20 - 3.20 = 15.00
15.00 ÷ 6(hotdogs) = 2.5
Add a 0 at the end: 2.50
So the cost of one hotdog is $2.50
( why does that hot dog cost that much ;-; )

The longest leg of a right triangle is 12 inches. The hypotenuse is 3 inches longer then twice the shortest leg. How long is the shortest leg and the hypotenuse of the triangle.
Answers
Answer:
Shortest Leg: 5 inches, Hypotenuse: 13 inches
Step-by-step explanation:
A right triangle follows the pythagorean theorem, a^2+b^2=c^2. C is the hypotenus. A combination found using this is 5, 12, and 13. To double check this, we know that the hypotenus is 2x+3, where x is the smallest leg.
Multiple Choice
Describe how the graphs of y = |x| and y = |x| – 15 are related.
A. The graphs have the same shape. The y-intercept of y = |x| is 0, and the x-intercept of the second graph is –15.
B.
The graphs have the same y-intercept. The second graph is steeper than y = |x|.
C. The two graphs are the same.
D. The graphs have the same shape. The y-intercept of y = |x| is 0, and the y-intercept of the second graph is –15.
Answers
Answer:
D is correct
Step-by-step explanation:
A graph of that sort will make a perfectly mirrored "V" shape, and with no offset, the bottom point will be on the y axis. This means that the first equation will intercept the y axis at zero, the second will intercept the y-axis at -15.
"A" may seem correct also, as the second graph will intercept the x-axis at -15, but it is not complete, as it will intercept that axis at +15 as well.
