Answer:
(a) What was the total of accounts written off during the first 11 months?
(b) As the result of a comprehensive analysis, it is determined that the December 31, 2010, balance of the Allowance for Bad Debts account should be $9,450. Show the adjustment required in the journal entry format.
a. Bad debt written off = Opening Balance in bad debt allowance account + Bad debt expense recognized during the period - Closing balance in bad debt allowance account
Bad debt written off = $13,966 + $21,297 - $9,797
Bad debt written off = $25,466
Therefore, the total of accounts written off during the first 11 months is $25,466
b. Date Description and Explanation Debit Credit
31-Dec Allowance for bad debts $347
($9,797 - $9,450)
Bad debt expenses $347
($9,797 - $9,450)
(To record adjustment of allowance of bad debt account)

I'm sorry I told everyone your secret," my sister said.
(apologized)
Write these sentences in reported speech using the verb given in brackets.
Answer:
My sister apologized for telling everyone my secret.
Explanation:
Reported (or indirect) speech is a way to express someone's words without explicitly quoting them. The original sentence is an example of direct (quoted) speech, which means that someone's exact words are repeated. An obvious sign of this are the quotation marks. When it comes to the reported speech, these quotation marks are omitted because a direct quotation is no longer present.
Problem 7-35 A satellite range prediction error has the standard normal distribution with mean 0 NM and standard deviation 1 NM. Find the following probabilities for the prediction error: (a) less than 1.17 NM Probability (b) between 1.04 NM and 1.99 NM Probability (c) greater than 0.93 NM Probability (d) between 0.24 NM and 0.73 NM Probability (e) less than or equal to 2.3 NM Probability (f) greater than 2.22 NM or less than .65 NM Probability (g) greater than or equal to 2.0 NM Probability\
Answer:
Kindly check explanation
Step-by-step explanation:
For a normal distribution with :
Mean(m) = 0
Standard deviation (s) = 1
Calculate :
(a) less than 1.17 NM Probability
Zscore = (x - m) / s = (1.17 - 0) / 1 = 1.17
P(z < 1.17) = 0.879
(b) between 1.04 NM and 1.99 NM Probability
Zscore = (x - m) / s = (1.04 - 0) / 1 = 1.04
P(z < 1.04) = 0.8508
Zscore = (x - m) / s = (1.99 - 0) / 1 = 1.99
P(z < 1.99) = 0.9767
(0.9767 - 0.8508) = 0.1259
(c) greater than 0.93 NM Probability
P(Z > 0.93) = 1 - p(Z < 0.93) = 1 - 0.8238 = 0.1762
(d) between 0.24 NM and 0.73 NM Probability
P(Z < 0.24) = 0.5948
P(Z <0.73) = 0.7673
0.7673 - 0.5948 = 0.1725
(e) less than or equal to 2.3 NM Probability
P(Z ≤ 2.3) = 0.9893
(f) greater than 2.22 NM or less than .65 NM
P(Z > 2.22) = 1 - p(Z < 2.22) = 1 - 0.9868 = 0.0132
P(Z < 0.65) = 0.7422
0.7422 - 0.0132 = 0.729
(g) greater than or equal to 2.0 NM Probability
P(Z ≥2) = 1 - p(Z ≤ 2)
1 - 0.97725 = 0.02275
the height h(t) of a trianle is increasing at 2.5 cm/min, while it's area A(t) is also increasing at 4.7 cm2/min. at what rate is the base b(t) chaging when the height h=15cm and the area A= 130cm2
Answer:
The base of the triangle decreases at a rate of 2.262 centimeters per minute.
Step-by-step explanation:
From Geometry we understand that area of triangle is determined by the following expression:
[tex]A = \frac{1}{2}\cdot b\cdot h[/tex] (Eq. 1)
Where:
[tex]A[/tex] - Area of the triangle, measured in square centimeters.
[tex]b[/tex] - Base of the triangle, measured in centimeters.
[tex]h[/tex] - Height of the triangle, measured in centimeters.
By Differential Calculus we deduce an expression for the rate of change of the area in time:
[tex]\frac{dA}{dt} = \frac{1}{2}\cdot \frac{db}{dt}\cdot h + \frac{1}{2}\cdot b \cdot \frac{dh}{dt}[/tex] (Eq. 2)
Where:
[tex]\frac{dA}{dt}[/tex] - Rate of change of area in time, measured in square centimeters per minute.
[tex]\frac{db}{dt}[/tex] - Rate of change of base in time, measured in centimeters per minute.
[tex]\frac{dh}{dt}[/tex] - Rate of change of height in time, measured in centimeters per minute.
Now we clear the rate of change of base in time within (Eq, 2):
[tex]\frac{1}{2}\cdot\frac{db}{dt}\cdot h = \frac{dA}{dt}-\frac{1}{2}\cdot b\cdot \frac{dh}{dt}[/tex]
[tex]\frac{db}{dt} = \frac{2}{h}\cdot \frac{dA}{dt} -\frac{b}{h}\cdot \frac{dh}{dt}[/tex] (Eq. 3)
The base of the triangle can be found clearing respective variable within (Eq. 1):
[tex]b = \frac{2\cdot A}{h}[/tex]
If we know that [tex]A = 130\,cm^{2}[/tex], [tex]h = 15\,cm[/tex], [tex]\frac{dh}{dt} = 2.5\,\frac{cm}{min}[/tex] and [tex]\frac{dA}{dt} = 4.7\,\frac{cm^{2}}{min}[/tex], the rate of change of the base of the triangle in time is:
[tex]b = \frac{2\cdot (130\,cm^{2})}{15\,cm}[/tex]
[tex]b = 17.333\,cm[/tex]
[tex]\frac{db}{dt} = \left(\frac{2}{15\,cm}\right)\cdot \left(4.7\,\frac{cm^{2}}{min} \right) -\left(\frac{17.333\,cm}{15\,cm} \right)\cdot \left(2.5\,\frac{cm}{min} \right)[/tex]
[tex]\frac{db}{dt} = -2.262\,\frac{cm}{min}[/tex]
The base of the triangle decreases at a rate of 2.262 centimeters per minute.
An electrican's shop charges $55
service fee plus $50 per hour for labor.
The linear equation that models
C= $50+ $55, where h is the number of labor hours and C is the total cost.
How much would the shop charge a customer for a job that takes 17hrs?
Answer:
$905
Step-by-step explanation:
$50×h+55=?
h=17 and you pay so $50×h
so $50×h=850
so now that you calculated the cost of the labor add the $55 dollar service fee
850+55=905

Two containers of gasoline hold a total of 50 gallons. The big container can hold 10 gallons less than twice the small
container. How many gallons does each container hold?
Answer:
The big container holds 30 gallons and the small container holds 20 gallons
Step-by-step explanation:
Let
The big container = x
Small container = y
The big container can hold 10 gallons less than twice the small
x = 2y - 10
Total gasoline in both containers = 50 gallons
x + y = 50
Substitute x = 2y - 10 into the equation
2y - 10 + y = 50
3y = 50 + 10
3y = 60
Divide both sides by 3
y = 60 / 3
= 20
y = 20 gallons
Recall,
x + y = 50
x + 20 = 50
x = 50 - 20
= 30
x = 30 gallons
The big container holds 30 gallons and the small container holds 20 gallons
Answer:
The big container has 30 gallons and the small container has 20 gallons.
Step-by-step explanation:
A candlemaker prices one set of scented candles at $10 and sells an average of 200 sets each week. He finds that when he reduces the price by $1, he then sells 50 more candle sets each week. A function can be used to model the relationship between the candlemaker's weekly revenue, R(x), after x one-dollar decreases in price.
Answer:
R(x) = -50x2 + 300x + 2000
Maximum revenue of $2450 with x = 3
Step-by-step explanation:
For each 1$ reduced of the price, he sells 50 more candle sets, so if he reduces x times the price by 1$, the final price will be:
price = 10 - x
And the number of sets sold will be:
sets = 200 + 50x
If the revenue is the price times the number of sets sold, we have that:
R(x) = (10 - x) * (200 + 50x)
R(x) = 2000 + 500x - 200x - 50x2
R(x) = -50x2 + 300x + 2000
To find the value of x that gives the maximum revenue, we use the formula of the vertex of the quadratic equation:
x_v = -b / 2a
x_v = -300 / (-100) = 3
And the maximum revenue is:
R(x_v) = -50*3^2 + 300*3 + 2000 = $2450

Answer:
C) 53°
Step-by-step explanation:
We know that <3 and <4 are equal, so we can solve for y.
3y+7=5y-73
7+73=5y-3y
80=2y
y=40
Now plug that in to <3
3y+7=3(40)+7=127
We know that <3 and <2 equal 180.
180-127=53
So <2=53°

Ship A receives a distress signal from the southwest, and ship B receives a distress from the same vessel from the north. At what location os the vessel in distress located? Describe how you arrived at your conclusion using complete sentences.
I've attached an image showing the coordinates of Ship A and Ship B.
Answer:
distressed vessel is located at (1, 1.5)
Step-by-step explanation:
From the image attached, we can see that;
Coordinate of ship A is (3, 4)
Coordinate of ship B is (1, 1)
Now, we are told that Ship A receives a distress signal from the southwest, and ship B receives a distress from the same vessel from the north.
This means that the distressed ship is somewhere in between ship A & B.
To solve this, we will extend the arrow line from Ship A in that same SW direction and we will do the same for ship B in the same North direction. Their point of intersection is where the distressed ship is located.
Now, if we do that, we will see that they will intersect at the point; (1, 1.5)
Thus,distressed vessel is located at (1, 1.5)

The coordinates of the point 3/10 of the way from A(-3,-8) to B(11,4) are ___?
Answer:
The coordinate of the point 3/10 of the way from A to B = (0.5, -4.4)
Step-by-step explanation:
to calculate the point 3/10 of the way from A to B, let us first find the difference in the coordinates of the point
Change in x coordinate: x₁ = -3, x₂ = 11
= x₂ - x₁ = 11 - (-4) = 11 + 4 = 15
3/10 of 15 = 0.3 × 15 = 4.5
This means that the point on the x axis is 4.5 points away from x₁
= -4 + 4.5 = 0.5
Change y coordinate: y₁ = -8, y₂ = 4
= y₂ - y₁ = 4 - (-8) = 4 + 8 = 12
3/10 of 12 = 0.3 × 12 = 3.6
This means that the point on the y axis is 3.6 points away from y₁
= -8 + 3.6 = -4.4
Therefore the coordinate of the point 3/10 of the way from A to B = (0.5, -4.4)
Question 8
A log with diameter 60 cm is 3 m in length its hollow centre is 20 cm in diameter.
Find the surface area of the log in cm', including the ends and the inside, correct to one decimal place.
Answer:
The surface area of the log including the ends and the inside is 80424.8 cm²
Step-by-step explanation:
To determine the surface area of the log with hollow center including the ends and the inside, we will find the surface area of the outer part of the log, surface area of the inner part of the log and the surface area of the two ends; and then sum everything up.
From the question,
Diameter of log = 60 cm
Length of log = 3 m = 300 cm
Diameter of hollow center = 20 cm
For the surface area of the outer part,
Area of the outer part = Circumference of the outer part × length
Circumference = 2πr = πd
∴ Area of the outer part = πd × l
(NOTE: d here is the diameter of the log)
d = 60 cm and l = 300 cm
Area of the outer part = 60π × 300 = 18000π cm²
For the surface area of the inner part,
Area of the inner part = Circumference of the inner part × length = πd × l
(NOTE: d here is the diameter of the hollow center)
d = 20 cm and l = 300 cm
Area of the inner part = 20π × 300 = 6000π cm²
For the surface area of one end
This is the difference between the area of the outer end and the area of the inner end
Here, we can determine the area by using
Area = πr², where r is the radius
Radius = Diameter / 2
Radius of outer end (R) = Diameter of log / 2 = 60cm / 2 = 30cm
Radius of inner end (r) = Diameter of hollow center / 2 = 20cm / 2 = 10 cm
∴ Surface area of one end = πR² - πr² = π(R²-r²)
= π (30²-10²)
= π (900 - 100)
= 800π cm²
This is the area of one end
For the two ends,
Area of the two ends = 2 × 800π cm² = 1600π cm²
Hence, the surface area of the log is 18000π cm² + 6000π cm² + 1600π cm²
Surface area of the log = 25600π cm²
Putting the value of π (π = 3.141592654)
Surface area of the log = 25600 × 3.141592654 cm²
Surface area of the log = 80424.77193 cm²
Surface area of the log = 80424.8 cm²
Hence, the surface area of the log including the ends and the inside is 80424.8 cm² (to one decimal place)
