what is the order of these brands from most to least popular?

Answers

Answer 1
Brand B; brand D; Brand C; Brand A
Answer 2

For this case we must write the numbers from highest to lowest.

We observe that the numbers are written in exponential notation.

Therefore, by rewriting we have:

Brand A:

[tex] 4.48 * 10 ^ 4 = 44,800
[/tex]

Brand B:

[tex] 3.84 * 10 ^ 7 = 38,400,000
[/tex]

Brand C:

[/tex]

Brand D:

[tex] 1.50 * 10 ^ 7 = 15,000,000
[/tex]

Ordering from highest to lowest we have:

[tex] 3.84 * 10 ^ 7 = 38,400,000

1.50 * 10 ^ 7 = 15,000,000

6.4 * 10 ^ 6 = 6,400,000

4.48 * 10 ^ 4 = 44,800

Devin is making a candle by pouring melted wax into a mold in the shape of a square pyramid. Each side of the base of the pyramid is 10 cm and the height of the pyramid is 11 cm. To get the wax for the candle, Devin melts cubes of wax that are each 3 cm by 3 cm by 3 cm. What is the minimum number of wax cubes Devin will need in need in order to make the candle? Show your work. Please explain.

Answers

The first thing you should do in this case is to calculate the volume of the square pyramid, which will be given by:
 V = (Ab * h) / 3
 Where,
 Ab: Area of the base.
 h: height of the pyramid.
 Substituting the values we have:
 V = ((10 * 10) * (11)) / 3
 V = 366.6666667 cm ^ 3
 We now calculate the volume of each cube, which will be given by:
 V '= L ^ 3
 Where,
 L: sides of the cubes.
 Substituting we have:
 V '= (3) ^ 3
 V '= 27 cm ^ 3
 The number of cubes will be:
 N = (V) / (V ')
 N = (366.6666667) / (27)
 N = 13.58024691
 Answer: 
 the minimum number of wax cubes Devin will need is 13 in order to make the candle

Answers

Answer: C.  0.215


Step-by-step explanation:

Given: A circle with a diameter of 124 m is inscribed in a square .

Thus side of square =124 m

Now, area of square=[tex](side)^2=(124)^2=15,376\ m^2[/tex]

Radius of circle=[tex]\frac{d}{2}=\frac{124}{2}=62\ m[/tex]

Area of circle=[tex]\pi\ r^2=3.14\times(62)^2=3.14\times3.14=12,070.16\ m^2[/tex]

Now, Area of shaded region= Area of square-Area of circle

Area of shaded region=[tex]15,376-12,070.16=3,305.84\ m^2[/tex]

Probability that a point picked at random in the square is in the shaded region

[tex]=\frac{\text{area of shaded region}}{\text{area of square}}=\frac{3305.84}{15376}=0.215[/tex]

Ken, Justin, and Tiff have read a total of 90
books from the library. Justin read 3 times
as many books as Ken and Tiff read 2
times as many as Justin. How many books
did Justin read?

Answers

okay so we gonna use k for Ken and j for Justin and T for Tiff. we are gonna try to use one letter to solve this in order for It to be more efficient and easy. so if Justin reads 3 times the amount of Ken than that is just basically 3k. and if Tiff reads twice as much as Justin than it's basically 6k because Justin is reads 3 times as Ken and that times 2 is 6k. so we are solving for k in order to know how much Ken reads. so k (for Ken) + 3k ( for justin) + 6k (for tiff) leaves you with 9k and they read 90 books in total. so 10k=90. so than you divide it which results in k=9. lastly if Justin reads 3 times as much as Ken than all you have to do is multiply 9 × 3 and you get 27 as the answer

a fund drive announces that it has raised 4376 which is 20% of its goal. How much more must be raised?

Answers

Answer:
It must raise an additional 17504

Explanation:
Assume that the amount to be raised is x.
Now, we are given that 20% of x is 4376, therefore:
0.2x = 4376
x = 4376/0.2
x = 21880

It has raised 4376, therefore:
amount left to raise = 21880 - 4376 = 17504

Hope this helps :)
You can solve this problem as follows:
 
 1. Let's call the amount: "y".
 
 2. The exercise says that 4376 which is 20% of its goal, so we have:
 
 y=4376
 20% of its goal=4376
 
 3. Then, we have the equation below:
 
 20y/100=4376
 0.20y=4376
 
 4. When we clear the variable "y", we obtain:
 
 y=4376/0.20
 y=21880
 
 5. Finally, we will have:
 
 21880-4376=17504
 
 6. How much more must be raised?
 
 The anwer is: 17504

[tex]s \: + \: 110 \: = \: 150 \\ s \: = \: 40[/tex]

Ans: 40 Student Tickets, 110 Adult Tickets
Final answer:

To solve this problem, set up a system of equations representing the number of student and adult tickets sold. Solve the system using substitution to find the numbers of each type of ticket sold.

Explanation:

To solve this problem, we can set up a system of equations to represent the number of student tickets and adult tickets sold.

Let x be the number of student tickets sold and y be the number of adult tickets sold.

We know that the total number of tickets sold is 150, so we have the equation:

x + y = 150

We also know that the total amount collected is $1000, so we have the equation:

3x + 8y = 1000

We can solve this system of equations using substitution.

From the first equation, we can solve for x in terms of y as:

x = 150 - y

Substituting this into the second equation, we have:

3(150 - y) + 8y = 1000

Simplifying, we get:

450 - 3y + 8y = 1000

Combining like terms, we get:

5y = 550

Dividing both sides by 5, we get:

y = 110

Substituting this value back into the first equation, we have:

x + 110 = 150

Simplifying, we get:

x = 40

Therefore, 40 student tickets and 110 adult tickets were sold.

A florist sold 15 arrangements in its first month of business. The number of arrangements sold doubled each month.


What was the total number of arrangements the florist sold during the first 9 months?

Answers

Answer:

total number of arrangements the florist sold during the first 9 months = 7665 arragements

Explanation:

Florist start a business.

In his 1st month Florist sold 15 arrangement.

He grow his business, he sold twice arrangements as compare to the previous month.

First month = 15

Second month = 2*15 = 30

Third month = 2*30 = 60

15, 30, 60 .....

we need to find the total number of arrangements in first nine months

This sequence is geometric series.

A geometric sequence is a sequence such that any element after the first is obtained by multiplying the preceding element by a constant called the common ratio which is denoted by r. The common ratio (r) is obtained by dividing any term by the preceding term, i.e.,

r = [tex] \frac{30}{15} = \frac{60}{30} = 2 [/tex]

Sum of Terms in a Geometric Progression ([tex] S_{n} [/tex])= [tex] \frac{a_{1} (r^{n} -1)}{r-1} [/tex]

where [tex] a_{1} [/tex] is first term = 15

n is the number of terms = 9

r is common ratio = 2

[tex] S_{9} =\frac{15(2^{9}-1)}{2-1} [/tex]

[tex] S_{9} =\frac{15*(512-1)}{1} [/tex]

[tex] S_{9} = 7665 [/tex]

total number of arrangements the florist sold during the first 9 months = 7665.

Segment AB has endpoints A(–4, 6) and B(1, 4). After a dilation, centered at the origin, the image of A is (–6, 9). Without measuring the distance, explain how you could find the image of B

Answers

If the image is centered at the origin you can divide the terms of the image from the preimage to find the scale or ratio at which it was dilated. In this case, you will use the points of A because the point b does not matter in this case.

[tex] \frac{-6}{-4} = 1.5 [/tex]  and [tex] \frac{9}{6} = 1.5[/tex] so the image is dilated by a scale of 1.5

now that we know the scale we multiply the points of B by the scale to get the image.    1*1.5 = 1.5  and 4*1.5 = 6 so the image for B is (1.5, 6) 

The image of point B is B'(1.5,6).and this can be determined by finding the dilation factor and then multiplying point B by the dilation factor.

Given :

Segment AB has endpoints A(–4, 6) and B(1, 4).After a dilation, centered at the origin, the image of A is (–6, 9).

In order to determine the image of point B, first, determine the dilation factor. let 'x' be the dilation factor, then:

[tex]-4\times x = -6[/tex]

[tex]x = \dfrac{3}{2}[/tex]

Now, after dilation the point B becomes:

Carlo wants to join gym.the total gym offers three options for the membership. Option1:pay as you go.pay only $6 each time You work out. Option2: Regular Deal. Pay $50 a month and $2 each time you workout.

Answers

The question is attached in the image.

1- Carlo thinks he will go to the gym 20 times this month. Calculate how much each of these options will cost Carlo for one month.
a- Pay as you go:
Total cost = 6 * 20 = $120
b- Regular deal:
Total cost = 50 + 2(20) = 50 + 40 = $90
c- All-in-one-price:
Total cost = $100
d- The least expensive for Carlo in this case would be the regular deal.

2- How many visits each month would make the cost of the Regular-Deal and the All-in-one the same?
Assume number of visits is x.
Regular deal = All in one
50 + 2x = 100
2x = 100 - 50
2x = 50
x = 25 visits

3a- It costs $300 to join the new Superfit Gym. You then pay $15 each month and $2 each time you work out. Carlo thinks he will use the gym 20 times each month for a year.
Calculate the cost of the Superfit gym for one year.
Total cost = initial payment + 15*number of month + 2*days of workout
initial payment = $300
15*number of months = 15 * 12 = $180
2*days of workout = 2*20*12 = $480
Total cost = 300 + 180 + 480 = $960

3b- How much will Carlo save during the first year if he uses the Superfit gym rather than the regular deal at the other gym?
First we will calculate the total cost of one year using the regular deal at the other gym as follows:
Total cost at other gym = monthly cost + cost of each workout
Total cost at other gym = 50(12) + 2(12)(20) = $1080
Then, we will calculate the difference to know the amount Carlo would save as follows:
Carlo would save = 1080 - 960 = $120

The roof of a factory rises vertically 7 ft through a horizontal run of 42 ft. What is the pitch of the roof?

Answers

Final answer:

The pitch of the roof, which rises vertically 7 ft through a horizontal run of 42 ft, is 2. This means the roof rises 2 inches for every 12 inches of horizontal run.

Explanation:

The question asks about calculating the pitch of a roof with a vertical rise of 7 ft and a horizontal run of 42 ft. The pitch of a roof is generally expressed as the amount of vertical rise per 12 inches of horizontal run. To find the pitch, we first need to calculate the rise per 12 inches of horizontal run.

Given:

Rise = 7 ft

Run = 42 ft

To find how much the roof rises for every 12 inches of run, we use the formula:

Pitch = (Rise / Run) × 12

Plugging in the given values:

Pitch = (7 / 42) × 12 = 2

Thus, the pitch of the roof is 2, meaning the roof rises 2 inches for every foot (12 inches) of horizontal run.

A pilot flies 720 miles from dallas, texas, to his first destination. after dropping off his cargo, he flies southeast 290 miles to his second destination. if the angle formed by his trip is 125°, what is the distance he will fly from the second destination back to dallas? 490 miles 918 miles 1,010 miles 842,026 miles

Answers

918 miles is the answer

Answer:

B) 918 miles

Step-by-step explanation:

Here with I have attached the figure of the story.

Here we need to find side c, which represents distance from the second destination back to Dallas.

We have to use the cosine formula to find the missing side.

If we are given two sides and one included angle, we can use the cosine formula and find the missing side.

a = 720, b = 290 and ∠C =125°

[tex]c^2 = a^2 + b^2 - 2ab cos C[/tex]

Now plug in the given values and simplify.

[tex]c^2 = {720}^2 + 290^2 - 2*720*290 cos 125[/tex]

[tex]c^2 = 518400 + 84100 - 417600 cos125[/tex]

[tex]c^2 = 602500 - (-239,525.5)\\c^2 = 602500 + 239,525.5\\c^2 = 842025.5[/tex]

Taking the square root on both sides, we get

c = 917.6
