Answer:
A, C, D
Step-by-step explanation:
All three triangles can be proved congruent, so corresponding angles are congruent.
∆JKL ≅ ∆MNO ≅ ∆PQR
__
So, the statements that are true are ...
A) rigid motion can map ∆JKL to ∆MNO
C) ∆JKL can be proved congruent to ∆PQR
D) ∠N can be proved congruent to ∠Q
_____
About the other choices
B. When triangles are congruent, there is some rigid motion that maps one to the other. It is false to say there is none such.
E. ∠L has a measure of 65° (not 55°), as do the corresponding angles in the other triangles.

-PLEASE ANSWER- An experiment was repeated a number of times and the following measurements were obtained:
52.3, 52.5, 52.2, 322, 19, 52.6
How would you obtain the best, single result from these measurements?
*Hint: Eliminate the outliers!*
Answer:
Step-by-step explanation:
From the given data, it can be observed that there are two number that are abnormal and extremely different from others, 322 and 19. Eliminating these two numbers would reduce the error that can be generated.
Then to obtain the best single result from the measurements, find the mean of the other numbers.
i.e 52.3, 52.5, 52.2, 52.6
Mean = [tex]\frac{52.3 + 52.5 + 52.2 + 52.6}{4}[/tex]
= [tex]\frac{209.6}{4}[/tex]
= 52.4
Thus the best single result that can be obtained is 52.4.

21 regular sodas and 49 diet sodas. What percentage of the sodas served were regular?
Answer:
30% of the sodas were regular sodas
Step-by-step explanation:
Add 21 and 49 to get the total number of sodas and 21+49=70. To get the percentage, divide 21 by 70 (21÷70) is 0.3 or 30%.
To check, do 30% (or 0.3) • 70 and you will get 21.
A number has the digits 6, 2, 9 to the nearest 100, the number rounds to 600 what is the number
Answer:
629
Step-by-step explanation:
rounds to 629 as t he closest hundred
This question is based on the concept of round - off rule. A number has the digits 6, 2, 9 to the nearest 100, the number rounds to 600 is 629.
Given:
A number has the digits 6, 2, 9 to the nearest 100, the number rounds to 600 what is the number.
According to the question,
The digit is given that 6, 2 and 9.
So, the digit at hundredth place is 6 and last two digit will be 29 or 92.
But, it is given that the number rounds to 600.
Thus, the number is at hundredth place is 6 and tenth place is 2 and at unit place is 9.
Therefore, the number would be 629 which is the number rounds to 600.
and the number 692 is not closest to 600.Thus we have to choose 29.
Hence, the number is 629.

The volume of a pyramid varies jointly with its height and the area of its base. A pyramid with a height of 16 feet and a base area of 78 square feet has a volume of 416 cubic feet. If a pyramid has a base area of 102 square feet and a volume of 238 cubic feet, find its height.
Answer:
7 ft
Step-by-step explanation:
base is b feet on each side
area of base is b² square feet
height is h feet
volume varies jointly with h and b²
V = kb²h
416 = k·78·16
k = ⅓
V = ⅓b²h
b² = 102
V = 238
h = 3V/b² = 7 ft

Which values are solutions to the inequality below
Answer:
11 and -11
Step-by-step explanation:
The square of 11 is 121. The square of -11 is also 121.
Answer:
Options C and F
Step-by-step explanation:
Check each answer:
6^2=36 but 36<64 so it cannot be A
8^2=64 but 64<64 (remember that even though they are equal to each other it doesn't meet the requirements of the inequality) so it cannot be B
11^2=121 and 121>64 so it can be C
-6^2=36 but 36<64 so it cannot be D (remember that squaring a number that is negative results in a positive number)
-8^2=64 but 64<64 so it cannot be E (see explanations for B and D)
-11^2=121 and 121>64 so it can be F
Therefore, the only two correct solutions are options C and F
A 10-ft vertical post casts a 14-inch shadow at the same time a nearby cell phone tower cast a 119-ft shadow. How tall is the cell phone tower?
The cell phone tower’s height is ___ ft?
Answer:
The cellphone towers height is 1020 ft.
Step-by-step explanation:
This question is solved using proportions, by a rule of three.
A 10-ft post casts a 14-inch shadow.
Each feet has 12 inches, which means that a post with 10 feet will cast a 14/12 = 1.167 ft shadow. How tall is the cell-phone tower with a 119-feet shadow?
10 feet post - 1.167 ft shadow
x feet tower - 119 feet shadow
Applying cross multiplication:
[tex]1.167x = 10*119[/tex]
[tex]x = \frac{1190}{1.167}[/tex]
[tex]x = 1020[/tex]
The cellphone towers height is 1020 ft.
Which is not a likely area of application of statistics in business?
a. Looking for patterns in a large marketing database.
b. Auditing supplier invoices for correct payment.
c. Making forecasts of several key product lines.
d. Questioning the executives' strategic decisions
Answer:
D.
Step-by-step explanation:
Statistics has a lot of usage in business.
Using statistics as well as statistical tools helps in the provision of data to be used for business analysis. With available data we can get patterns in a a large database. Statistics can be used for auditing, as in question option b. For option c, statistics can be used for making business forecasts after the careful observation of trends and patterns that are in the data.
Option d does not make use of statistics. It has nothing to do with statistics neither does it have a computational feature.
Therefore, d.) questioning the executive's strategic decision is the answer to this question

Geo joins Fitness Plus Gym. He pays a membership fee of $25 to join. Geo pays $550 for the year. Write and solve an equation to find the amount he pays per month. Let a represent the amount he pays per month
Answer:
Geo pays $43.75 per month for the gym.
Step-by-step explanation:
Given that:
Membership fee = $25
Amount paid for year = $550
Let,
a be the amount he pays per month.
And there are 12 months in a year.
Total amount = Membership fee + 12 * Per month fee
550 = 25 + 12a
550 - 25 = 12a
525 = 12a
12a = 525
Dividing both sides by 12
[tex]\frac{12a}{12}=\frac{525}{12}\\a=43.75[/tex]
Hence,
Geo pays $43.75 per month for the gym.

A rectangle has a width measuring 5 ft. and a length measuring x −2. Write and solve an inequality that represents the values of x for which the area of the rectangle will be at least 35 square feet
Answer:
The inequality is: [tex]5(x - 2) \geq 35[/tex]
The solution is: [tex]x \geq 9[/tex]
Step-by-step explanation:
Area of a rectangle:
The area of a rectangle with length l and width w is given by:
A = lw
In this question:
Width 5 feet.
Length x - 2.
For which the area of the rectangle will be at least 35 square feet
Equal or greater than 35. So
[tex]5(x - 2) \geq 35[/tex]
[tex]5x \geq 45[/tex]
[tex]x \geq \frac{45}{5}[/tex]
[tex]x \geq 9[/tex]
