Answer:
244 tiles
Step-by-step explanation:
These "border" problems can be a little tricky.
The tiles are 1 ft square, so an integer number of them fit along each of the sides. The 40-ft side will take 40 tiles for its border, and the 80-ft side will take 80 tiles.
The total number of tiles along each of the four sides is ...
40 + 80 + 40 + 80 = 240 . . . tiles
However, there is also a tile in each of the corners. There are 4 of those, so the total number of tiles surrounding the pool is ...
240 +4 = 244 tiles
__
Alternate solution
For a border of width w, the outside area of the pool plus the border is ...
A = LW = (80 +2w)(40 +2w) = 80·40 +240w +4w²
The area of the pool is ...
A = LW = (80)(40) = 80·40
Subtracting the area of the pool from the total area including the border gives ...
border area = (80·40 +240w +4w²) -(80·40) = 240w +4w²
We know the width of the border is 1 foot, so w=1 and the border area is ...
border area = 240·1 +4·1² = 244 . . . . square feet
Each tile is 1 square foot, so 244 tiles are needed for the border.

It can help to draw yourself a diagram. It can also help to make a small model using blocks, Scrabble tiles, Legos, jigsaw puzzle pieces, squares cut from paper, or even coins (pennies). Anything that will give you an idea of how to count the tiles required to make a border can be helpful.

So for this answer I got 5 hrs. > 38.13 - 12 = 26.13/4.75 = 5 (rounded). However, my answer is wrong. Not sure how else I can solve this. Please help.

Answer:
38.13 = 12 +4.75h
5.5 hours
Step-by-step explanation:
(a) The charge (c) for renting a bike for h hours is ...
c = helmet charge + hourly charge × hours
c = 12.00 +4.75h
To find the number of hours when the charge is 38.13, we would use the equation ...
38.13 = 12.00 +4.75h
__
(b) To solve this 2-step linear equation, we first subtract the constant
26.13 = 4.75h
then we divide by the coefficient of the variable.
26.13/4.75 = h ≈ 5.5
Amanda rented the bike for 5.5 hours.

Step-by-step explanation:
Given the expression;
[tex]\frac{x}{x^2-16} -\frac{3}{x-4}[/tex]
According to difference of two square;
x² - 16 = x²-4² = (x+4)(x-4)

[tex]\frac{x}{(x+4)(x-4)} - \frac{3}{x - 4}\\[/tex]
Find the LCM
[tex]= \frac{x-3(x+4)}{(x+4)(x-4)} \\= \frac{x-3x-12}{(x+4)(x-4)}\\= \frac{-2x-12}{(x+4)(x-4)}\\= \frac{-2(x-6)}{(x+4)(x-4)}[/tex]

Explanation:
f(x) is the outer function, so the final output -8 corresponds to f(x)
We see that f(-4) = -8 in the first column of the table. I'm starting with the output and working my way backward to get the input. So we started with -8 and worked back to -4.
Then we move to the g(x) function to follow the same pattern: start with the output and move to the input. We start at -4 in the g(x) bubble and move to 3 in the x bubble.
In short, g(3) = -4
So,
f(g(x)) = f(g(3)) = f(-4) = -8
We see that x = 3 leads to f(g(x)) = -8

This question did provide some clues to answer this question. Every week, the area covered by the algae is multiplied by 2^1.
To find the area cover increase by the algae per day, the exponent should be divided by 7 since there are 7 days in a week. Hence, every day, the area covered by the algae multiplies by 2^(1/7). In other words, 1 day after the algae was spotted, the area is 12.5 * 2^(1/7), which answers part B.
10 days after the algae was spotted, the area covered by the algae is 12.5 * 2^[(1/7)*10] = 33.6475... , which rounds up to 34 and answers part A.

Answer:
x = 13.48
Step-by-step explanation:
Given that,
Angle, [tex]\theta=26^{\circ}[/tex]
base, b = x
Hypotenuse, H = 15
We need to find the measure of x. It can be solved using trigonometry i.e.
[tex]\cos\theta=\dfrac{b}{H}[/tex]
Put all the values,
[tex]\cos(26)=\dfrac{x}{15}\\\\x=15\times \cos(26)\\\\x=13.48[/tex]
So, the value of x is equal to 13.48.
As a salesperson at Max’s Mattresses, Richard earns $250 plus $15 for each mattress he sells. Which equation can Richard use to determine how much earnings, e, he will make after he sells, m, matresses?
Answer:
e = 250 + 15m
Step-by-step explanation:
The earnings or "e" are determined by the solution of the $250 he's earned from the start and the $15 he earns are dependent on the amount of mattresses he's sold so "m" has to be multiplied by the 15.

Answer:
Proportional
Step-by-step explanation:
Proportional functions can be written as [tex]y=kx[/tex], where [tex]k[/tex] is some constant of proportionality. Plugging in (x,y) pair into this function will yield a constant of proportionally of [tex]k=\frac{3}{2}[/tex] and since this constant is maintained through all the coordinate pairs in the table, the table is proportional.
