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).
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.

Answer:
a. x^2 - 1
b. x^2 - 6x + 9
c. [tex]\dfrac{3x + 1}{x^2 + x}[/tex]
Step-by-step explanation:
a.
(x + 1)(x - 1) =
= x^2 - x + x - 1
= x^2 - 1
b.
(x - 3)^2 =
= (x - 3)(x - 3)
= x^2 - 3x - 3x + 9
= x^2 - 6x + 9
c.
[tex] \dfrac{3 + \frac{1}{x}}{1 + x} = [/tex]
[tex] = \dfrac{x(3 + \frac{1}{x})}{x(1 + x)} [/tex]
[tex] = \dfrac{3x + 1}{x + x^2} [/tex]
[tex] = \dfrac{3x + 1}{x^2 + x} [/tex]

What is a transversal line?A transversal is a line that intersects two lines on the same plane at two different points. When those two intersected lines are parallel their alternate angles, interior angles and exterior angles are equal and the converse of this statement is also true.
We know when two parallel lines are intersected by a transversal their interior alternate angles are equal.
∴ (2x - 20)° = 90°
2x = (90 - 20)°.
2x = 70°.
x = 35°.

Please explain how you got your answer please. it’ll help me.
Answer:
The answer is no solutions.
Step-by-step explanation:
use systems of equations!
first, rewrite both equations so that the sum or difference includes the same variable.
[tex]9-4x=6y\\-4+2x=-3y[/tex]
notice how i made sure the coefficients that have x and y respectively line up.
with this, i can cancel out the x variables by making 2, and -4 as -8 (8+-8=0).
rewrite the equation.
[tex]2(9-4x=6y)\\4(-4+2x=-3y)\\[/tex]
distribute.
[tex]18-8x=12y\\-16+8x=-12y[/tex]
now we can successfully cancel out the x variable!
[tex]18=12y\\-16=-12y[/tex]
uh oh! it seems we can also cancel out the y variables..
[tex]18=0\\-16=0[/tex]
18 is not equal to 0 and neither is -16. because of this, we can conclude there is no solution for this system of equations.
hope this helps!!

X-9y=17 find y (use integers or fractions for any numbers in the expression)
Let's see what to do buddy...
_________________________________
[tex]x - 9y = 17[/tex]
Subtract the sides of the equation minus x
[tex] - 9y = 17 - x[/tex]
Divided the sides of the equation by -9
[tex] \frac{ - 9}{ - 9}y = \frac{17 - x}{ - 9} \\ \\ [/tex]
[tex]y = \frac{ - (17 - x)}{9} \\ [/tex]
[tex]y = \frac{x - 17}{9} \\ [/tex]
_________________________________
And we're done.
Thanks for watching buddy good luck.
