Johnson wants to buy something for himself. He has a budget of $105 to spend on $25 t-shirts, $10 cd's, and $5 books. He wants to buy 10 items and wants to buy as many books as t-shirts and cd's combined. How many of each item should he buy?
Explain please!
Answers
Answer:
2 t-shirts, 3 cd's, 5 books.
Step-by-step explanation: Johnson wants to spend $105 in total, get 10 items total, and get at least 1 t-shirt, 1 cd, and 1 book. If he did not want to buy 10 items then he could buy 21 books, 10 cd's and 1 book, or 4 t-shirts and 1 book. But because of all the conditions Johnson should buy 2 t-shirts ($50), 3 cd's ($30), and 5 books ($25). $105 total, and as much of each item as possible.

3 sevenths
3 forth
Answers
Answer:
c wich is sevenths
Step-by-step explanation:
The probability the teacher that chooses a girl to write the date on the board is :
C) 3 sevenths.
"Probability"
Given:
Boys =12
Girls =9
Total number of students = 12 + 9 = 25.
So the probability of choosing a girl is = n(girl) / n(all students) = [tex]\frac{9}{25}[/tex]
This is close to 3 sevenths.

The diagram shows triangle ABC. Calculate the length of AC
Answers
Given:
In triangle ABC, AB=8.2 cm, C=13.5 cm and angle A= 81 degrees.
To find:
The length of AC.
Solution:
According to the Law of Sines:
[tex]\dfrac{\sin A}{a}=\dfrac{\sin B}{b}=\dfrac{\sin C}{c}[/tex]
Using Law of Sines, we get
[tex]\dfrac{\sin A}{a}=\dfrac{\sin C}{c}[/tex]
[tex]\dfrac{\sin (81^\circ)}{13.50}=\dfrac{\sin C}{8.2}[/tex]
[tex]\dfrac{\sin (81^\circ)\times 8.2}{13.50}=\sin C[/tex]
[tex]\sin^{-1}\dfrac{\sin (81^\circ)\times 8.2}{13.50}= C[/tex]
[tex]C\approx 36.86^\circ[/tex]
Using angle sum property, we get
[tex]\angle A+\angle B+\angle C=180^\circ[/tex]
[tex]81^\circ+\angle B+36.86^\circ=180^\circ[/tex]
[tex] \angle B =180^\circ-81^\circ-36.86^\circ [/tex]
[tex] \angle B =62.14^\circ [/tex]
Now,
[tex]\dfrac{\sin A}{a}=\dfrac{\sin B}{b}[/tex]
[tex]\dfrac{\sin (81^\circ)}{13.50}=\dfrac{\sin (62.14^\circ)}{b}[/tex]
[tex]b=\dfrac{13.50\times \sin (62.14^\circ)}{\sin (81^\circ)}[/tex]
[tex]b\approx 12.08[/tex]
Therefore, the length of AC is 12.08 cm.

Write an equation for expense (blue line)
I would really appreciate if someone helped me I'm not understanding this.
Answers
Answer: y = 0.0005x+1
This is the same as saying y = (1/2000)x + 1
===============================================================
Explanation:
The blue line goes through (0,1) and (2000,2)
The slope is
m = (y2-y1)/(x2-x1)
m = (2-1)/(2000-0)
m = 1/2000
This says that each time we move up 1, we move to the right 2000 units.
Think of it as slope = rise/run = 1/2000
The slope 1/2000 means that each time you make 2000 soccer balls, it will cost you $1000. Keep in mind that y is in thousands (eg: y = 1 means 1000). This further implies that the marginal cost is ($1000)/2000 = $0.50 = 50 cents. The marginal cost is the cost to make one extra unit.
The fraction 1/2000 converts to the decimal form 0.0005 after using a calculator. So m = 0.0005 is the decimal form of the slope.
The y intercept of the blue line is b = 1 as this is the location where the blue line crosses the vertical y axis. The y intercept represents the fixed costs needed to set up production, for example: buying the machinery needed is a fixed cost.
-------------------
Since m = 0.0005 and b = 1, we go from y = mx+b to y = 0.0005x+1
We could say y = (1/2000)x + 1, though I think it's probably easier to use a decimal in this case.
