A married couple buys 280 shares of stock for a total investment of $8,722. They decide to sell all of their shares in the fund at the listing value shown below. Name of Fund Offer Price NAV $31.05 CEH Mid-Cap $31.20 Determine if the couple makes a profit or loss, and how much per share. a. loss of $0.05 per share b. loss of $0.10 per share c. profit of $0.05 per share d. profit of $0.10 per share
The couple will make a loss of $0.10 per share.
What is the loss per share?
In order to determine the loss per share, the average total investment would be subtracted from the NAV. If the NAV is greater than the average total investment, the couple make a profit, if this is not the case, the couple would make a loss.
Average total investment = $8722 / 280 = $31.15
Loss = $31.05 - $31.15 = $-0.10

the square root of 55
7
the square root of 32
Answer:
the square root of 55, or 7.42
Step-by-step explanation:
Use the Pythagorean Theorem, or a²+b²=c², where a and b are the sides or "legs" of the triangle and c is the hypotenuse.
a is 3, b is x, and c is 9
If you plug that into the equation, you get 3²+x²=8²
We can make this 9+x=64 by squaring the 3 and 8.
Then we can subtract 9 from each side to get x=55.
Finally, take the square root of 55 to get √55 or 7.42.

Susan works part-time in a local video store. Her salary varies directly as the number of hours
worked. Last week she earned $144 for working 16 hours. This week she earned $378. How
many hours did she work this week?
Answer:
42 hours
Step-by-step explanation:
First divide 144 by 16 to get the money per hour wich is 9 then divide 378 by nine and you get the awnser, 42 hours.
Thank you
42 hours Susan worked this week to $378.
Given that, Susan's salary varies directly as the number of hours worked.
We need to find out how many hours did she work this week.
What is the direct variation?Direct variation is a type of proportionality wherein one quantity directly varies with respect to a change in another quantity. This implies that if there is an increase in one quantity then the other quantity will experience a proportionate increase. Similarly, if one quantity decreases then the other quantity also decreases. Direct variation is a linear relationship hence, the graph will be a straight line.
According to the question, last week she earned $144 for working 16 hours. This week she earned $378.
Let the number of hours she works this week be x.
So, the proportion is 144:16::378:x
⇒144×x=16×378
⇒x=42
Hence, 42 hours Susan worked this week to $378.

Two lines are represented by the equations -1/2y=6x+10 and y=mx for which value of m will the lines be parallel
Answer:
-12
Step-by-step explanation:
So to start we need to know what makes a line parallel. In an equation we know that for lines to be parallel they must have the same slope(m).
Then, we need to know the slope-intercept form of an equation. The slope intercept form is [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope of the line and [tex]b[/tex] is the y-intercept. In this problem where can see the second equation is already in this form.
Now that we know we need to find the slope, and we know that the second equation is in slope-intercept form we're going to convert the fist equation into the correct form.
To do this, we know we need to make sure [tex]y[/tex] is the only thing on the left side of the equal sign. Currently, on the left side of the equal sign we have [tex]-\frac{1}{2} y[/tex] so we have to divide both sides by [tex]-\frac{1}{2}[/tex] to get [tex]y=-12x -20[/tex]
Now that we have it converted to slope-intercept form, we are going to look for what represents the slope or [tex]m[/tex] in the equation. In this case the slope would be -12, so any line with a slope of -12 will be parallel.

Create a linear equation in the slope-intercept fo
form that contains points (2,-8) and (6,-4).
Answer:
y = x - 10
Step-by-step explanation:
slope - intercept form: y = mx + b
y2 - y1 -4 - ( -8 ) 4
--------- = ------------- = -------- = 1
x2 - x1 6 - 2 4
---------------------------------------------------------
y = mx + b
y = 1x + b
pick whichever point you want to use, for this I'll use (2, -8)
-8 = 1( 2) + b
-8 = 2 + b
-2 -2
-10 = b
y = 1x - 10 or y = x - 10

The lateral edge of a square prism is 30 cm long and it is inclined at an
angle of 70 degrees with the base. If the volume of the prism is 1,500 cm3,
1. what is the base edge?
2. What is the lateral area of the prism?
3. What is the total area of the square prism?
Answer:
1
[tex]B = 7.07 \ cm[/tex]
2
[tex]A =848.4 cm^2 [/tex]
3
[tex]A_T = 948.37 \ cm^2 [/tex]
Step-by-step explanation:
From the question we are told that
The lateral edge of a square prism is [tex]d = 30 \ cm = 0.3 \ m[/tex]
The angle of inclination is [tex]\theta = 70^o[/tex]
The volume of the prism is [tex]V = 1500\ cm^3[/tex]
Generally the base of the prism is mathematically represented as
[tex]B = \sqrt{\frac{V}{ d} }[/tex]
=> [tex]B = \sqrt{\frac{1500}{ 30} }[/tex]
=> [tex]B = 7.07 \ cm[/tex]
Generally the lateral area of the prism is mathematically represented as
[tex]A = 4 * B * d[/tex]
=> [tex]A = 4 * 7.07 * 30 [/tex]
=> [tex]A =848.4 cm^2 [/tex]
Generally the total area of the prism is mathematically represented as
[tex]A_T = 2 * B + A[/tex]
=> [tex]A_T = 2 * (7.07) + 848.4[/tex]
=> [tex]A_T = 948.37 \ cm^2 [/tex]

Your teacher asks the class to evaluate the expression (3³)¹. Your classmate gives an incorrect answer of 81. Evaluate the expression. Then find the likely error.
The most likely error is that, the student multiplied 27 by 3, after the first computation
What are expressions?Expressions are mathematical statements that are represented by variables, coefficients and operators
How to determine the error in the calculation?The expression is given as
(3^3)^1
As a general rule, we start by evaluating the expression in the inner bracket
So, we have
(3^3)^1 = (3 x 3 x 3)^1
Evaluate the products
So, we have
(3^3)^1 = (27)^1
Next, we evaluate the exponent
So, we have
(3^3)^1 = 27
The above implies that the value of the expression is 27 and not 81 as the student solved
The most likely error is that, the student multiplied 27 by 3, after the first computation
Hence, the value of the expression is 27 and not 81 and the most likely error is that, the student multiplied 27 by 3, after the first computation

Bailey Checks her time records to see how fast she runs each day. On Tuesday, She Ran 3 3/4 Miles. On Friday, she ran 7 2/8 miles. How many more Miles did she run on Friday than Tuesday?
Step-by-step explanation:
I guess, she is checking how FAR she runs each day (and not how fast ...).
how many more miles did she run on Friday ?
we get this by calculating the difference between the 2 values. that is what subtraction is for.
7 2/8 - 3 3/4
as long as we have the numbers as combination of full and fraction numbers, we can subtract the full numbers right away.
7 2/8 - 3 3/4 = 4 2/8 - 3/4
now we convert both numbers to full fractions :
4 2/8 - 3/4 = (32 + 2)/8 - 3/4 = 34/8 - 3/4
and then we bring both fractions to the same denominator, in this case 1/8 :
34/8 - 3/4 = 34/8 - 3/4×2/2 = 34/8 - 6/8 = 28/8
now we can simplify
28/8 = 7/2 = 3 1/2
so, she ran 3 1/2 miles more in Friday than on Tuesday.
FYI
I just wanted to show you the full formal flow of such a calculation.
but we could have gotten the result quicker by recognizing that we can simplify the numbers already at the beginning :
7 2/8 - 3 3/4 = 7 1/4 - 3 3/4 = 4 1/4 - 3/4 = 3 2/4 = 3 1/2
