Alan purchased 16 shares of company stock for $390.40. A month later, the total value of his shares fell to $291.20. What is the current price per share if each share costs the same?
A.
$6.20
B.
$18.20
C.
$24.04
D.
$24.40
Answers
Answer: $18.20
Step-by-step explanation:
390.40/16 to find the initial costs of the shares. That would be $24.40 per share. However, since the stock has fallen, you would do that same division, but with the new value. 291.20/16, which is $18.20
Answer:
$18.20 per share is the value of each stock currently
Step-by-step explanation:
Take the value the stocks are worth now and divide by the number of shares
291.20/16
$18.20 per share
$18.20 per share is the value of each stock currently

cost of the small and large cans of peanuts?
A Small can for $6.29 and large can for $7.00
B Small can for $4.86 and large can for $6.00
C Small can for $4.00 and large can for $7.00
D Small can for $7.00 and large can for $9.00
Answers
Answer:
the answer is c.
Step-by-step explanation:
4 x 5 + 7 x 7 = 69
4 x 3 + 7 x 9 = 75
Cost is small can for $4.00 and large can for $7.00.
What is the system of equation?One or many equation having same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
Let S be the number of small cans and L be the number of large cans.
According to the question,
One student sold three small cans and nine large cans of peanuts for a total of $75.
That means the equation is ;
3S + 9L = 75 {equation 1}
And similarly for another student;
5S + 7L = 69 {equation 2}
Now we have two system of the equation.
3S + 9L = 75 {equation 1}
5S + 7L = 69 {equation 2}
Using elimination process,
we multiply 5/3 to equation 1,
5S + 15L = 125
And subtract equation 1 to the equation 2,
we get L = 7 and S = 4
Therefore, small can for $4.00 and large can for $7.00

After 4 minutes of reading, Aaron was on page 14 of his book. After 8 minutes he was on page 20. Which equation models the page number, y, in terms of minutes x?
Group of answer choices
y = 8x + 1.5
y = 1.5x + 8
y = −1.5x + 8
y = –8x + 1.5
Answers
Answer:
The answer would be (B) y = 1.5x + 8
Step-by-step explanation:
The equation that models the number of pages (y) and number of minutes (x) is y = 1.5x + 8.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is Aaron who is reading a book. After 4 minutes of reading, Aaron was on page 14 of his book and after 8 minutes he was on page 20.
Now -
(x) represents the number of minutes and (y) is the number of pages.
At x = 4, y = 14
At x = 8, y = 20
The slope of the line will be -
m = (20 - 14)/(8 - 4)
m = 6/4
m = 3/2
The general equation can be written as -
y = 3x/2 + c
20 = 3/2 x 8 + c
20 = 12 + c
c = 8
Now, we can write the equation as -
y = 1.5x + 8
Therefore, the equation that models the number of pages (y) and number of minutes (x) is y = 1.5x + 8.

please hurry this is due in an hour and a half
Answers
Answer:
See below.
Step-by-step explanation:
We have:
[tex]\frac{\sqrt3}{\sin(\theta)}=2[/tex]
And we want to find two different angles between 0 and 180 that satisfy this equation.
First, let's get our sine out of the denominator. Notice that this is the same as:
[tex]\frac{\sqrt3}{\sin(\theta)}=\frac{2}{1}[/tex]
Cross-multiply:
[tex]2\sin(\theta)=\sqrt{3}[/tex]
Divide both sides by 2:
[tex]\sin(\theta)=\frac{\sqrt{3}}{2}[/tex]
Here you go! I'll have the answer for you if you scroll down, so check it when you're ready!
#2 is correct. However, double check #3. The answer's down there too... :)
[Blank space...]
[More blank space...]
[And more...]
Answer for 1)
We have:
[tex]\sin(\theta)=\sqrt{3}/2[/tex]
So, at what points between 0 and 180 does sine equal √3/2?
If we refer to the unit circle, we can see that this happens twice: at 60.
Thus, the second time it occurs will be at 180-60 or 120.
So:
[tex]\theta=60\textdegree\text{ or } 120\textdegree[/tex]
Answer for 3)
So you are correct for the first three. So:
[tex]\sin(54)=t[/tex]
However, sine stays positive. So, our angle must be between 0 and 180.
So, instead of 180+54, it should be 180-54, giving us:
[tex]\sin(54)=\sin(126)=t[/tex]

Step-by-step explanation:

The value of p is w/3 - 2h/3.
What is equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S
Given:
2h = W-3p
For p move w
2h - w = -3p
Now, divide both side by 3
2h/3 - w/3 = -3p/3
2h/3 - w/3 = -p
p= w/3 - 2h/3
Hence, the value of p is w/3 - 2h/3.
