Answer:
In a typical kite as shown in picture, it is symmetric around PQ and PQ is perpendicular with RN.
=> Two right triangles PNT and PRT are congruent.
=> angle PRT = angle PNT = 34 deg
=> angle RPT = 90 - angle PRT = 90 - 34 = 56 deg
=> Option A is correct.

A long year-end status report for work is 144 pages long. You need to print 16 copies for a meeting next week. How much is the paper going to cost for those reports? Paper is sold in reams (500 pages) for $3.54 each.
Give your answer to the nearest cent, only for the paper you use (partial reams are OK)
Submit Question
Answer: The paper going to cost $16.31 for those reports.
Step-by-step explanation:
Given, the length of a long year-end status report for work = 144
If we ned to print 16 copies for a meeting next week, the total number of pages required = 16 *144
= 2304
Since, the paper is sold in reams of 500 pages = $3.54
Then, cost of one page = (Cost of a ream of 500 pages) ÷ 500
= $3.54 ÷ 500
= $ 0.00708
Cost of total number of pages required = 2304x (cost of one page)
= 2304 x ($ 0.00708)
= $ 16.31232 ≈ $16.31
Hence, the paper going to cost $16.31 for those reports.
The cooler at a picnic contained 4 apple juice boxes, 8 orange juice boxes, and 6 fruit punch juice boxes. A juice box is selected at random. What is the probability of the complement of choosing an orange juice box? (first answer will get brainliest)
1/18
4/9
5/9
17/18
Answer:
[tex] p(O)=\frac{8}{18}=\frac{4}{9}[/tex]
And since we want the complement of choosing an orange juice box the answer would be:
[tex] P(O') =1 - P(O) = 1-\frac{4}{9}= \frac{5}{9}[/tex]
And the nest answer for this case is:
5/9
Step-by-step explanation:
For this case we know that we have 4 apple juice boxes, 8 orange juice boxes, and 6 fruit punch juice boxes, so then the size of the sample space is:
[tex] 8+4+6= 18[/tex]
Then we can find the probability of selecting an orange juice box with the definition of Laplace given by:
[tex] p =\frac{possible}{total}[/tex]
And for this case the possible cases are 4 and the total 18 so then the probability is given by:
[tex] p(O)=\frac{8}{18}=\frac{4}{9}[/tex]
And since we want the complement of choosing an orange juice box the answer would be:
[tex] P(O') =1 - P(O) = 1-\frac{4}{9}= \frac{5}{9}[/tex]
And the nest answer for this case is:
5/9
Two lengths of a triangle are shown.
6
ft
6
ft
[Not drawn to scale]
Which could be the length of BC?
Answer:
11 ft
Step-by-step explanation:
Given the two lengths of a triangle as
AB = 6ft
AC = 6ft
This is an isosceles triangle because only 2 sides are equal.
In an isosceles triangle, the sum of 2 (sides) lengths must be greater than the other length.
Therefore, let's assume the following:
i) AC + AB > BC
6 + 6 > BC
12 > BC (BC is less than 12)
BC < 12
ii) BC + AC > AB
BC + 6 > 6
BC > 6 - 6
BC > 0
Therefore the range of values for BC =
0 < BC < 12
Since BC must be bigger than one of the lengths and it must also be less than the sum of the 2 sides. The length of BC could be 11 because it is less than (6+6) 12 and greater than 6.

A) In terms of s, the area of the base is ____________ .
B) The formula for the volume of a pyramid gives the equation ___________.
C) Solving this equation shows that s = __________
Answer:
[tex](a)s^2\\(b)162=2s^2\\(c)s=9$ ft[/tex]
Step-by-step explanation:
(a)Base Area
Side length of square base=s
Area of a Square of side length s=[tex]s^2$ ft^2[/tex]
(b)
Height =6 ftVolume=[tex]162 $ ft^3.[/tex]Volume of a Pyramid[tex]=\frac{1}{3}X$Base Area X Height[/tex]
Substituting the given values, we have:
[tex]162=\frac{1}{3}Xs^2 X 6\\\\162=2s^2[/tex]
(c)Solving the equation derived from (b)
[tex]162=2s^2\\$Divide both sides by 2\\s^2=81\\s^2=9^2\\s=9$ ft[/tex]
Solving this equation shows that s =9 ft.

Two bell P and Q ring at intervals of 3 hours and 4 hours, respectively. After how many hours will the two bells first ring simultaneously
Answer:
This problem is same as finding the least common multiple (LCM) of 3 and 4.
3 = 3
4 = 2 x 2
=> LCM = 3 x 2^2 = 12 (3 appears once, 2 appears twice)
=> After 12 hours, two bell P and Q ring simultaneously.

Since 2 and 8 are factors of 16, you only need to find a multiple of 16 in between 67 and 133 which is simple. I chose 80.
Answer:
128
Step-by-step explanation:
It's asking you to find a number between 67 and 133 that you could divide by 2, 8 and 16 and won't get a remainder.
128 can be divided by 2, 8 and 16 without a remainder.

At a sale this week, a sofa is being sold for $153.60 .This is a 76% discount from the original price. What is the original price?
Answer:
$21473.33
Step-by-step explanation:
Let the original price be x
76% discount gives $153.60
This means 24/100 * x = $153.60
X= 153.60 * 100 /24 = $21473.33
The original price of the sofa is $21473.33.
What is discounted price?Discount is the difference in price between the selling price of an object and the price listed on the object marked price.
Given that, a sofa is being sold for $153.60, which was on the 76% discount.
Let the original price be x,
x - 76% of x = $153.60,
⇒ 24/100 · x = $153.60
⇒ x = 153.60 · 100 /24 = $21473.33
Hence, the original price of the sofa is $21473.33.

How many tissues should a package of tissues contain? Researchers have determined that a person uses an average of 60 tissues during a cold. Suppose a random sample of 10 comma 000 people yielded the following data on the number of tissues used during a cold: x overbar equals 53 comma s equals 23. We want to test the alternative hypothesis Upper H Subscript a: muless than60. State the correct rejection region for alpha equals 0.05 .
Answer:
Null hypothesis: [tex] \mu \geq 60[/tex]
Alternative hypothesis: [tex] \mu <60[/tex]
Since the sample size is large enough we can assume that the distribution for the statistic is normal so then in order to find the critical value for this test taking in count the significance level given of 0.05 we need to look in the normal standard distribution a value who accumulates 0.05 of the area in the left and would be:
[tex] z_{crit}= -1.64[/tex]
Step-by-step explanation:
For this case we have the following data given:
[tex] \bar X = 53[/tex] represent the sample mean
[tex] s = 23[/tex] represent the sample deviation
[tex]n = 10000[/tex] represent the sample size.
We want to test for this case if the true mean is less than 60 so then the system of hypothesis are:
Null hypothesis: [tex] \mu \geq 60[/tex]
Alternative hypothesis: [tex] \mu <60[/tex]
Since the sample size is large enough we can assume that the distribution for the statistic is normal so then in order to find the critical value for this test taking in count the significance level given of 0.05 we need to look in the normal standard distribution a value who accumulates 0.05 of the area in the left and would be:
