Answer:
11. B 12. C 13. B
Step-by-step explanation:
11. Since segment MR bisects segment QO, side QP and side PO are equal. In the problem it states that angle MQP is congruent to angle ROP. The the angles QPM and OPR are vertical, so they are equal. That is enough evidence to conclude the answer.
12. ADC is bisected by BD, so that bisects AC too, which makes both sides equal. BD is perpendicular to AC, making right angles on both sides. The curves at angle A and angle C show that they are congruent. That should be enough evidence to show that it is congruent by ASA.
13. Triangle cannot be congruent by having the same angles, only similar since the lengths can be different. Congruent triangle means that the sides and angles are the same.
Good luck...hope this helped ;)
What is the equation of the line that is parallel to the line represented in the table and goes through the point (-10, -2)?
Answer:
y = -3/2x - 17
Step-by-step explanation:
First you need to find the slope, since the lines are parallel the slopes would be the same as points of the other line on the table. When finding the slope you get -3/2, when you have the slope you need to find the y-intercept or in other words in y=mx+b, the "b" in the equation. In order to find the y-intercept you have to plug in the values of the point (-10,-2) so then the equation would look like -2 = -3/2(-10) + b. Then you would solve for b. Then when you put the components together you get y = -3/2x - 17.
find the value of x.
I Need to show the equations please, and show my work
Answer:
15
Step-by-step explanation:
since both equations are set with a right angle, the equation must be equal to 90 degrees. So you set the equation as
13+x+4x+2=90
add the x variables together and the constants separately
15+5x=90
then subtract 15 from both sides.
15+5x=90
-15 -15
5x=75
then divide 5 from both sides.
75/5= 15
so x is 15 :).
Answer:
It shows a 90° angle split into 2 separate angles so,
[tex]13 + x + 4x + 2 = 90\\\\5x + 15 = 90\\\\5x = 75\\\\x = 15[/tex]
Basically, the total angle measure of the given angles [90°, (13 + x)°, and (4x + 2°) equals 180°. Take away 90 from 180 and you get 90, then solve for x using what's left: 13 + x + 4x + 2 = 90. You get x = 15.
Benjamin owns a small Internet business. Besides himself, he employs nine other people. The salaries earned by the employees are given next in thousands of dollars (Benjamin's salary is the largest, of course): 30, 30, 45, 50, 50, 50, 55, 55, 60, 75.
Required:
a. Determine the mean, median, and mode for salary.
b. Business has been good! As a result. Benjamin has a total of $25.000 in bonus pay to distribute to his employees. One option for distributing bonuses is to give each employee (including himself) $2500. Add the bonuses under this plan to the original salaries to create a new data set. Recalculate the mean, median, and mode. How do they compare to the originals?
c. As a second option. Benjamin can give each employee a bonus of 5% of his or her original salary. Add the bonuses under this second plan to the original salaries to create a new data set. Recalculate the mean, median, and mode. How do they compare to the originals?
d. As a third option, Benjamin decides not to give his employees a bonus at all. Instead, he keeps the $25,000 for himself. Use this plan to create a new data set. Recalculate the mean, median, and mode. How do they compare to the originals?
Answer:
a) mean μ = 50 median M = 50 mode Md = 50
b) mean μ₂ = 52,5 median M = 52,5 mode Md = 52,5 all vales increased in 2,5 ( thousands of $) the same quantity of individuals incements
c) mean μ₃ = 52,50 median M = 52,5 mode Md = 52,5 The same values obtain in b)
d) mean μ₃ = 52,50 median M = 50 and Mode 50
Step-by-step explanation:
a) Mean μ is the average then:
30 30 45 50 50 50 55 55 60 75
μ = 50
The median M, is the central (fifth value) 50
And the mode
Md = 50
b) Adding 2,5 ( in thousands of $) to each one of the employees
32,5 32,5 47,5 52,5 52,5 52,5 57,5 57,5 62,5 77,5
The mean μ₂ = 52,5 $, since the average value has to be increased by the common increased number
The median M = 52,5 and also the mode Md = 52,5
c) 31,5 31,5 47,25 52,5 52,5 52,5 57,75 57,75 63 78,75
The mean μ₃ = 52,50
The median M = 52,50
The Mode Md = 52,50
d) 30 30 45 50 50 50 55 55 60 100
μ₄ = 52,5
Median M = 50
Mode Md = 50
The LCM of two numbers in 2310 and their HCF.
is 30 . If one number is 210, find the other number.
Answer:
The other number is 330
Step-by-step explanation:
The computation of the other number is shown below:
As we know that
HCF × LCM = Product of Two Numbers
So,
30 × 2310 = 210 × other number
Now
The other number is
= (30 × 2310) ÷ 210
= 330
hence, the other number is 330 and the same is to be considered
We simply applied the above formula so that the correct answer could come

Patrick wants to estimate the percentage of parents who use cloth diapers. He asks a randomly selected group of 125 parents whether or not they use cloth diapers. What is the statistic?
Answer: The percentage of parents who use cloth diapers in the sample is the statistic.
Step-by-step explanation:
A statistic is the measure of a particular characteristic in the sample which is nothing but a subset of population.Here, the concern is to estimate the percentage of parents who use cloth diapers.
He took a sample of 125 parents to enquiry whether or not they use cloth diapers.
So, the percentage of parents who use cloth diapers 9in the sampl is the statistic.
Answer: The percentage of parents who use cloth diapers in the sample is the statistic.
The width of a rectangle measures (5.5d+9.7f)(5.5d+9.7f) centimeters, and its length measures (5.1d-3.5f)(5.1d−3.5f) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?
Answer:
21.2d + 12.4f
Step-by-step explanation:
Given that:
Width of rectangle = (5.5d+9.7f) centimeters
Length of rectangle = (5.1d-3.5f) centimeters
Perimeter of a rectangle : 2 (length + Width)
2 [(5.1d-3.5f) + (5.5d+9.7f)]
2[5.1d - 3.5f + 5.5d + 9.7f]
2[10.6d + 6.2f]
= 21.2d + 12.4f
Hence, the perimeter is :
21.2d + 12.4f)

By the property that says that "corresponding parts of the congruent triangles are congruent"
Corresponding angles (Including right angle) will be equal.
m∠A = m∠X = 180° - (90° + 37°) = 53°

In the diagram below, the radii of the two concentric circles are 3 centimeters and 7 centimeters, respectively.
What is the area of the shaded region?
Answer:
125.6 cm²
Step-by-step explanation:
Area of the shaded region = area of larger circle - area of the smaller circle
Area of the smaller circle = πr²
π = 3.14, r = 3 cm
Area of smaller circle = 3.14*3² = 3.14*9 = 28.26 cm²
Area of larger circle = πr²
π = 3.14, r = 7
Area of larger circle = 3.14*7² = 3.14*49 = 153.86 cm²
Area of the shaded region = 153.86 - 28.26 = 125.6 cm²

what is 12 rounded off to the nearest 10
Answer:
10
Step-by-step explanation:
Since 12 is closer to 10 than 20, the nearest ten is 10, which is the answer.
Answer:
10
Step-by-step explanation:
This is the answer because:
1) We always have to look at the rounding digit (this digit is located right next to the tens digit in this problem).
2) Since the ones digit is smaller than 5, it has to round down to 10. If the digit was 5 or greater, than it would be 20.
Therefore, the answer is 10.

From the sum of 3x +4y -3xy and 5x +3y -2xy subtract the sum of 2x +y – 3xy and 10x -9y -8xy.
Answer:
-4x + 16y + 3xy
Step-by-step explanation:
The sum of 3x + 4y - 3xy and 5x + 3y - 2xy is 8x + 7y - 5xy.
The sum of 2x + y - 3xy and 10x - 9y - 8xy is 12x - 8y - 11xy.
Subtract the sum of the second pair from the first pair by changing the sign of the subtrahend. The result is -4x + 16y + 3xy
