You have a garden in your backyard that measures 15 meters by 20 meters. You want to place stepping stones around the perimeter of the garden. The area of the new garden (original garden + stone placed around the perimeter) is 336m². What is the width of the stone border? (Assume the border has the same width around the entire perimeter.) Equation used = bi Width of stone border = meters
Answer:
0.5 m
Step-by-step explanation:
Given that the dimensions of the garden are 15 meters by 20 meters.
The area of the new garden (original garden + stone placed around the perimeter) is 336m².
Let d be the width of the border having stepping stones as shown in the figure. The shaded region in the figure is the area having stepping stones.
The area including the shaded region [tex]= (15+2d)(20+2d) m^2[/tex]
[tex]\Rightarrow 336 = (15+2d)(20+2d) \\\\\Rightarrow 336 = 300+ 70 d +4d^2 \\\\\Rightarrow 4d^2 +70d+300-336=0 \\\\\Rightarrow 4d^2 +70d-36=0 \\\\\Rightarrow 2d^2 +35d-18=0 \\\\\Rightarrow 2d^2 +36d-d-18=0 \\\\\Rightarrow (2d-1)(d+18)=0 \\\\\Rightarrow (2d-1)=0, \; or \; (d+18) \\\\\Rightarrow d= 0.5\;or -18 \\\\[/tex]
As the width of the stone border can't be a negative value, so taking the positive value.
Hence, the width of the stone border is 0.5 m.

4.) Are imperfect square roots rational or irrational?
Answer:
Irrational
Step-by-step explanation:
Answer:
Real numbers have two categories: rational and irrational. If a square root is not a perfect square, then it is considered an irrational number. These numbers cannot be written as a fraction because the decimal does not end (non-terminating) and does not repeat a pattern (non-repeating).

What is the equation of the line, in general form, that passes through the point (1, 1) and has a y-Intercept
of 2
Ox+y20
Ox-y + 20
OX-y-20
Answer:
y = -x + 2
Step-by-step explanation:
The equation of line is often written in the form;
y = mx + c
y and x are the coordinates
m is the slope
c is the intercept
From the given parameters;
c = 2
(1,1) are the coordinates
Let us find the slope of the line;
1 = m(1) + 2
1 = m + 2
m = 1- 2 = -1
The equation of the line is;
y = -1x + 2
y = -x + 2

The fox population in a certain region has a continuous growth rate of 6 percent per year. It is estimated that the population in the year 2000 was 19100.
(a) Find a function that models the population t years after 2000(t=0 for 2000).
Hint: Use an exponential function with base e.
Your answer is P(t)=
(b) Use the function from part (a) to estimate the fox population in the year 2008.
Your answer is (the answer must be an integer)
Answer
a)
[tex] P(t) = 19100. e^{0.06t} [/tex]
b) P(8) =30866
Step-by-step explanation
Use formula:
[tex] P(t) = P. e^{rt} [/tex]
a)
Here, P = 19100
r = 6% = 0.06
[tex] P(t) = 19100. e^{0.06t} [/tex]
b) t = 2008 - 2000 = 8
[tex] P(8) = 19100. e^{0.06\times 8} [/tex]
[tex] P(8) = 19100. e^{0.48} [/tex]
[tex] P(8) = 19100\times 1.616\\\\
P(8) = 30,865.6\\\\P(8) \approx 30,866[/tex]

Mason inspects 73.5 phones each day. He must inspect no fewer than 1,470 phones each month. How many days will Mason need to work to reach his goal by the end of the month.
Answer:
20 days
Step-by-step explanation:
We have 31 days in one month
Mason must have inspected 1470 after 31 days
He inspects 73.5 phones per day. Hence,
73.5 phones =>1 days
1470 phones =>
1470 ÷ 73.5 => 20 days
Hence, Mason will need 20 days to reach his goal.
A car travels a distance of 104 miles in 4 hours. What is the speed in miles per hour
Answer:
26
Step-by-step explanation:
104 miles
4 hours
so do 104/4, then you get 26
so 26 miles per an hour
Speed of the car is 26 miles per hour.
What is speed?Speed can be measured as the distance traveled by a body in a given period of time. The SI unit of speed is m/s.
Speed formula can be used to find the speed of objects. The formula for the speed of a given body can be expressed as,
Speed = Distance ÷ Time
Given,
Car travels distance = 104 miles
Time taken to travel 104 miles = 4 hours
Speed = distance/ time
Speed of car
= 104/4
= 26 miles per hour
Hence, 26 miles per hour is the speed of car.

The rate of change is 62.5 miles per hour.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
Take two points from graph as (1, 50) and (5, 300)
So, the rate of change is
=(300-50)/ (5-1)
= 250 /4
= 62.5
Hence, the rate of change is 62.5 miles per hour.

Points (−6, 3) and (−6, −3) on the coordinate grid below show the positions of two dogs at a park:
A coordinate plane is shown. There is a point at negative 6, 3 labeled Dog 1. There is a point at negative 6, negative 3 labeled Dog 2.
Which statement best describes the relationship between the positions of the two players?
A. Dog 1's position is Dog 2's position reflected across the y-axis; only the signs of the y-coordinates of Dog 1 and Dog 2 are different.
B. Dog 1's position is Dog 2's position reflected across the x-axis; only the signs of the y-coordinates of Dog 1 and Dog 2 are different.

D. Dog 1's position is Dog 2's position reflected across the y-axis; only the signs of the x-coordinates of Dog 1 and Dog 2 are different.
9514 1404 393
Answer:
B. Dog 1's position is Dog 2's position reflected across the x-axis; only the signs of the y-coordinates of Dog 1 and Dog 2 are different.
Step-by-step explanation:
It is generally useful to compare the answer choices to the problem statement. Here, the problem statement gives two points with identical x-coordinates and opposite y-coordinates.
Any answer choice saying the signs of the x-coordinates are different can be rejected immediately.
It also can be useful to draw yourself a picture. If you plot the points, you can see that the x-axis bisects them. The reflection is not across the y-axis, so any answer choice saying it is can be rejected.
The appropriate description is ...
B. Dog 1's position is Dog 2's position reflected across the x-axis; only the signs of the y-coordinates of Dog 1 and Dog 2 are different.
1. What would be the first step in solving the equation below for r ?
A = 4r
a add 4 to both sides
b subtract 4 to both sides
c divide 4 to both sides
d multiply 4 to both sides
Answer:
C; multiply 4 to both sides
Step-by-step explanation:
When you want to solve for a variable, you always want to isolate it.
So, to move 4, we have divide:
[tex]\frac{A}{4}[/tex] = [tex]\frac{4r}{4}[/tex].
The 4 in 4r is "one'd" out, and now we have 1r, or simply r.
Now, we have r = A/4

By the end of the first quarter of a football game, Al had gained 62 yards and had lost 21 yards. Al Lost an additional 15 yards and gained 18 yards in the second quarter. Replacing represents his total yardage for the first half of the game
Answer:
Y = Q + 44
Step-by-step explanation:
We can easily write an equation for this scenario by making a variable for the unknown number of yards at the start of the first quarter (which would be represented by the letter Q) and then adding or subtracting the gained/lost yards in the second quarter. This would give us the total yardage for the first half of the game which will be represented by the variable Y.
Y = Q + 62 - 21 - 15 + 18 ... we can simplify this by adding and subtracting the given values
Y = Q + 44
