A postal carrier delivers mail to 20 mailboxes on one side of a long street. Beginning with the first mailbox, the carrrier takes 5 seconds to sort and put the mail in each mailbox, and the mailboxes are 100 feet apart. How fast (in feet per second) must the carrier walk in order to complete delivery to all 20 mailboxes in 10 minutes? Answer in decimal form as a.b (for example, 9.7).
Answers
Answer:
3.8 seconds
Step-by-step explanation:
Time taken to sort the mail is [tex]5[/tex] seconds
Let time taken to go from one mailbox to the next be [tex]x[/tex]
Distance between the mailboxes is [tex]100[/tex] ft
So, sorting the mail for one mailbox and going to the next will be done in [tex](5+x)[/tex] seconds
This will happen 19 times and 5 seconds will be needed to sort the mail for the last mail box. The carrier will have to deliver to all the 20 mailboxes in 10 minutes. So, the total time taken will be
[tex]19(5+x)+5=10\times 60\\\Rightarrow 19(5+x)=595\\\Rightarrow 5+x=\dfrac{595}{19}\\\Rightarrow x=\dfrac{595}{19}-5\\\Rightarrow x=\dfrac{500}{19}\ \text{s}[/tex]
Time taken to go from one mailbox to the other is [tex]\dfrac{500}{19}\ \text{s}[/tex]
Speed is given by
[tex]v=\dfrac{100}{\dfrac{500}{19}}\\\Rightarrow v=3.8\ \text{ft/s}[/tex]
The speed at which the carrier has to move from one mailbox to the next is 3.8 seconds.

To find s:
s² = 64
s = √64
s = ±8
length cannot be negative, hence it is positive 8
b. Perimeter of a square is 4s = P, where P is the perimeter and s is the side length.

Alan says that two lines in the coordinate plane are perpendicular if and only if the slopes of the lines are m and 1m. Identify and correct two errors in Alan’s statement.
Answers
Answer:
First, two lines are perpendicular if one has slope m, and the other has slope -1/m (Not 1m as Alan says)
That is the first error of Alan.
Now, there is another error.
If m = 0, then -1/m tends to minus infinity (in this case we would have a vertical line).
But we can not really divide by zero, so we should state that:
m can not be zero, if a line is horizontal, the perpendicular line must be vertical.
Alexander is a stockbroker. He earns 11% commission each week. Last week, he sold $5,400 worth of stocks. How much did he make last week in commission? If he averages that same amount each week, how much did he make in commission in 2011?
Answers
Answer: 594 and 30888
Step-by-step explanation:
5400 x 0.11 = 594
594 dollars in commission of one week
52 weeks in a year
52 x 594 = 30888 dollars made in 2011
594 dollars in commission of one week.
$30888 he make in commission in 2011.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Stocks sold= $5400
Commission each week = 11%
So, Commission on Stocks sold
= 5400 x 0.11
= 594
Thus, 594 dollars in commission of one week.
As, 1 Year = 52 weeks
So, He can make in 2011 = 52 x 594 = $30888

The cost y (in dollars) of renting a segway for x hours is y=30x+25. Find the initial fee and the cost per hour.
Answers
Given:
The cost y (in dollars) of renting a segway for x hours is
[tex]y=30x+25[/tex]
To find:
The initial fee and the cost per hour.
Solution:
We have,
[tex]y=30x+25[/tex] ...(i)
The slope intercept form of a linear equation is
[tex]y=mx+b[/tex] ...(ii)
where, m is slope is b is y-intercept or initial value.
From (i) and (ii), we get
[tex]m=30,b=25[/tex]
The value of m is 30, so the slope is 30. It means cost per hour is $30.
The value of b is 25, so y-intercept is 25. It means the initial fee is $25.

If three quarters of a number decreased by twenty is equal to eighty two, what is that number?
Answers
A number is :
[tex]x[/tex]
_________________________________
Three quarters of it means :
[tex] \frac{3}{4}x \\ [/tex]
_________________________________
Decrease by 20 means :
[tex] \frac{3}{4}x - 20 \\ [/tex]
_________________________________
Equals to 82 means :
[tex] \frac{3}{4}x - 20 = 82 \\ [/tex]
_________________________________
What is that number ?
x asked so we must solve the above equation for x.
Let's do it....
[tex] \frac{3}{4}x - 20 = 82 \\ [/tex]
Plus sides 20
[tex] \frac{3}{4}x = 82 + 20 \\ [/tex]
[tex] \frac{3}{4}x = 102 \\ [/tex]
Multiply sides by 4
[tex]3x = 102 \times 4[/tex]
Divided sides by 3
[tex]x = \frac{102 \times 4}{3} \\ [/tex]
[tex]x = \frac{102}{3} \times 4 \\ [/tex]
Simplify
[tex]x = 34 \times 4[/tex]
[tex]x = 136[/tex]
So that number is 136 .
