A sports apparel company surveyed the market about the size of T-shirts people most frequently buy, small, medium, large, or extra-large. The
table shows the survey results.
T-Shirt Size Number of responses
small
11
mediurn
37
large
83
extra-large
19
To help Its sales, the company should focus on producing size
T-shirts. Approximately % of T-shirts the company
makes should be medium and large T-shirts to match the market preference. If the total number of T-shirts sold in a month is 45,000,
of these will likely be size small.

Answers

Answer:

To help Its sales, the company should focus on producing Large

T-shirts. Approximately 80% of T-shirts the company

makes should be medium and large T-shirts to match the market preference. If the total number of T-shirts sold in a month is 45,000, 3,300

of these will likely be size small.

Step-by-step explanation:

In the survey, Large t-shirts are most frequently bought so they should be the primary focus if the company is trying to make more money.

To find the percentage of shirts that the medium and large shirts make up, first you find the total amount of shirts (11+37+83+19=150), then you will find how many mediuma and large shirts (37+83=120). Percentage is (120/150)*100=80%

To find the number of small shirts you can set up a proportion.

[tex]\frac{11}{150} =\frac{x}{45,000}[/tex], then cross multiply

150x=11*45,000

150x=495,000

x=3,300

eliana has 40$. she plans to save $25 every week to buy a plane ticket that costs $365. how many weeks will it take her to save such amount?

help pleaseeee <3!!!

options are:
25 weeks
40 weeks
13 weeks
31 weeks

Answers

Step-by-step explanation:

365-40=325 (to find what she needs to make)

It would be 13 weeks but it really take 11 weeks

Thomas has $30 to spend at the amusement park. Rides cost $2 each and admission at the gate is $6. What is the maximum number of rides that Thomas can go on?
A.2r + 6 < 30

B.2r + 6 = 30

C.6r + 2 = 30

D. 6r + 2 > 30

Answers

Answer:

B.2r+6=30

Explanation:

It costs $6 dollars just to get in. Subtract 6 from 30. 30-6=24

Divide 24 by 2. 24 divided by 2 equals 12.

Let the number of rides = r

Multiply the price per ride by number of rudest over 2r, you then add the admission to that to get 2R + 6

He has $30 so the total he can spend has to be less than or equal to $30

2r + 6 <= 30

The closest answer is A.

Rewrite the equation 2x + 6y = 7 in slope-intercept form.

y = -(2/3)x + 1 1/3
6y= -2x +7
y = -2x + 1 1/6
y = -(1/3)x + 1 1/6

Answers

Answer: y = -2x + 1 1/6

Steps:
2x + 6y = 7
2x + y = 7/6
y = 7/6
y = -2x + 7/6
y = -2x + 1 1/6

I Got y = -2x + 1 1/6 :D

Please help me figure out the answer to this I'm a bit confused

Answers

Answer:

y= 1/2x + 1

Step-by-step explanation:

Refer to y=mx+b, m=slope and b= y-intercept

First, you find the slope: you can find the slope by finding the rise over run between two points. Rise= 1, Run=2. The slope is rise/run (rise over run), so the slope would be 1/2 (one half).

Next, find the y-intercept. It is where the line touches the y-axis. Here, it would be 1.

Finally, put these in y=mx+b form:

y=(slope)x+(y-intercept) ---> y= 1/2x + 1

I tried my best to explain everything, I hope you found this helpful!

The answer is. y = 1/2x + 1
