Answers
Answer:
31
Step-by-step explanation:
The entire straight line is 180 degrees. So, if angle a is 25 degrees we would subtract that from 180. This would give us 155 degrees. You would then add 2x and 3x together to get 5x. 155/5x would be 31. Your x value is then 31.
Answer and Step-by-step explanation:
We know that a is equal to 25.
Let's subtract that from the entire angle measure of line segment AB, which is 180.
180 - 25 = 155.
Now, we need to find the value of x. We can do this by adding together the other two angles, and equal it to 155.
155 = 2x + 3x
155 = 5x
31 = x
So, the value of x is 31.

Hey there!
In (a) part we can see that a person delivers approximately 120 newspapers in 3 hours. Kate will deliver 30 × 3 = 90 newspapers. So, (a) part is the answer.
In (b) part, a person delivers 40 newspapers in 4 hours, Kate delivers 30 × 4 = 120 newspapers. So, Kate is faster, (b) option cancelled.
In (c) a person delivers 110 newspapers in 4.5 hours. Kate will deliver 30 × 4.5 = 135 papers, that's again greater. Option (c) cancelled.
Option (d), we can easily cancel it out. But I'm showing the work; a person delivers 20 newspapers in 4 hours, Kate delivers 30 × 4 = 120 newspapers, much faster than the person.
Hence option (a) is the answer.

In the following graph is the zero located at -4 have an
even or odd multiplicity?
Answers
Answer:
Even multiplicity at x = -4
Step-by-step explanation:
If the graph of a function crosses x-axis then the multiplicity of the function at that zero will be odd.
If the graph touches the x-axis at a point then the function will have an even multiplicity at the particular zero.
From the given graph graph touches the x-axis at x = -4
Therefore, multiplicity of the function is even at x = -4

Walden’s family is shopping for a reclining chair. The chair the family decided on has a retail price of $800 plus 5% sales tax at four stores. Each store is offering a different promotion.
Store
Promotional Offer
A
$75 instant rebate
B
10% off sale
C
5% off sale plus store pays sales tax
D
a “no tax” sale—the store pays the tax
Which store has the best deal?
Answers
Answer: B is the correct answer
Step-by-step explanation:
If you do the math for each question to get a price a leaves you with 725 and b leaves you with 720 and c leaves you with 760 while d leaves you paying 800 so the lowest amount would be B.
Answer: B
Step-by-step explanation:
I'm pretty sure its B.
Since all 4 stores have a 5% sales tax already on them, we do:
800 x 5%
800 x 5/100
800 x 0.5 = 40
So now we go to all the stores and see which one is less than $40.
Answer A = 40 - 75 = -35 (Which is a price the store would have to pay but that's not a good option)
Answer B = 4
40 x 10%
40 x 10/100
40 x 0.10 = 4
Answer C = So if the store already pays sales tax which would be the 5% then our answer is $40
Answer D = This would just be $800 since the store says "no tax" and the store pays the 5%.
So, i'm pretty sure the answer is B instead of C. (i say this because a lot of people were saying it was C but C is completely wrong.)
1. What is the equation of a parabola that has a vertex at (-2, 4) and goes through the point (0,8)?
Answers
Answer:
y - k = (x + 2)^2
Step-by-step explanation:
The vertex equation of a vertical parabola is
y - k = a(x - h)^2, where (h, k) is the vertex.
We are given h = -2, k = 4, x = 0 and y = 8 and need to find the value of a.
8 - 4 = a(0 + 2)^2, or
4 = 4a, so a must be 1.
Then the desired equation is:
y - k = (x + 2)^2

Doctors are interested in seeing if lifting weights to alleviate back pain is effective. Twenty five volunteers are asked to rank their level of pain on a scale from one to ten. For the next two months, they then exercise for 2 months with a physical therapist. The volunteers focus on different weight lifting exercises that strengthen the back. Twenty five volunteers are again asked to rank their level of pain on a scale from one to ten. Was the amount of pain less after completing the exercises? What type of test would they conduct to test this claim?
Answers
Answer:
Comparing means from dependent samples.
Step-by-step explanation:
In the scenario described above, the 25 sampled individuals were used to test the effect of weightlifting on alleviating back pain. The samples used were not changed nor altered during the study as the same subjects who were tested to measure their level of pain before lifting weight were the same group subjected to the actual weight lifting test and again had their level of pain tested. Since only one group was involved in the study ( a single group was tested on neutral and actual treatment). Hence, the study used dependent samples to compare the average level of pain.

A company is designing a new cylindrical water bottle. The volume of the bottle will be 124 cmcubed. The height of the water bottle is 7.1 cm. What is the radius of the water bottle? Use 3.14 for pi.
Answers
Answer:
2.35cm
Step-by-step explanation:
Given data
Volume= 124cm^3
Height= 7.1cm
The expression for the volume of a cylinder is given as
V= πr^2h
substitute
124=3.142*r^2*7.1
124=22.3082r^2
r^2= 124/22.3082
r^2= 5.55
r= √5.55
r=2.35cm
Hence the radius of the cylindrical bottle is 2.35cm
What is the surface area of the figure? 12TT cm2 24TT cm2 144TT cm2 36TT cm2
Answers
Answer:
The surface area of the figure is;
36·π cm²
Step-by-step explanation:
The parameters of the figure are;
The shape of the figure = A sphere
The radius of the sphere, r = 3 cm
The surface area of a sphere, A = 4·π·r²
Therefore, for the given sphere, we have;
The surface area of the sphere, A = 4 × π × (3 cm)² = 4 × π × 9 cm²
∴ The surface area of the figure (sphere), A = 36·π cm².

Step-by-step explanation:
Given the scores of the students: 3, 4, 4, 5, 5, 6, 8, 10, 10, 12, 15, 18
To find the box plot that represents the data set, we need to find:
Min, Q1, median, Q3, and Max, which are all represented on a box plot.
Min = 3
Max = 18
Median = the average of the 6th and 7th data value = (6+8)/2 = 14/2 = 7
Q1 = the average of the 3rd and 4th data values = (4+5)/2 = 4.5
Q3 = the average of the 9th and 10th data values = (10+12)/2 = 11
The box plot that closely represented all these values is the box plot in option 3.
