A plot of land is about 13,000 ft by 8000 ft. Approximately how many square miles is this? Round to the nearest whole number.
Answer:
4 square miles
Step-by-step explanation:
A plot of land is about 13,000 ft by 8000 ft.
1 mile = 5280 ft
To convert feet to miles we divide by 5280
13000 ft = [tex]\frac{13000}{5280}=2.4621[/tex]
8000 ft = [tex]\frac{8000}{5280}=1.5152[/tex]
Now we find the area
To find area we multiply the miles
2.4621* 1.5152= 3.73057392
When we round to nearest whole number it becomes
4 square miles
I need help please and fast what is 3 1⁄8 − 1 7⁄8 =
I don't know what the symbol means or what to do.
Answer:
Step-by-step explanation:
That weird symbol means "element". In our case, the elements of the domain (the x-values) are -15, -6, -1. Which tells us that we are going to sub each one of the numbers into the equation and solve it for the corresponding y value. That in turn gives us the coordinate point. The equation is
x + y = 6
Subbing in first -15 for x:
-15 + y = 6 and
y = 6 + 15 so
y = 21 and the coordinate point is (-15, 21).
Subbing in -6 for x:
-6 + y = 6 and
y = 6 + 6 so
y = 12 and the coordinate point is (-6, 12).
Subbing in -1 for x:
-1 + y = 6 and
y = 6 + 1 so
y = 7 and the coordinate point is (-1, 7)
The second choice is the one you want.
Just remember that x is the domain and any elements in the domain go in for x.
Also remember that y is the range and any elements in the range go in for y

1. The county fair charges $1.25 per ticket for the rides. Jermaine bought 25 tickets for the rides and spent a total of $43.75 at the fair. Jermaine spent his money only on ride tickets and fair admission. The price of the fair admission is the same for everyone. Use y to represent the total cost and x to represent the number of ride tickets.
(a) Write a linear equation that can be used to determine the cost for anyone who only pays for ride tickets and fair admission.
(b) Define your variables.
Answer:
a). Linear equation; y=1.25 x+12.5
b). The variable are x and y, where;
y is the total cost at the county fair
x is the number of tickets per ride
Step-by-step explanation:
Step 1: Define variable in the linear equation
y=mx+c
where;
y=The total cost at the county fair
x=the number of tickets per ride
m=Cost per ticket ride
c= fair admission price
Step 2: Derive linear equation
In or case;
y=$43.75
m=$1.25 per ticket ride
x=25 tickets
c=unknown
replacing;
43.75=(1.25×25)+c
c=43.75-31.25
c=12.5
The fair admission price=c=12.5
Replacing in the Linear equation;
y=1.25 x+12.5

You are setting up a zip line in your yard. You map out your yard in a coordinate plane. An equation of the line representing the zip line is y=2x+4y=2x+4. There is a tree in your yard at the point (−4, 11)(−4, 11). Each unit in the coordinate plane represents 1 foot. Approximately how far away is the tree from the zip line? Round your answer to the nearest tenth.
Solving this problem actually requires us the use of the distance formula of point to a line.
The formula is:
distance = | a x + b y + c | / sqrt (a^2 + b^2)
So we are given the equation:
y = 2 x + 4
rewriting:
y – 2 x – 4 = 0 --> a = -2, b = 1, c = -4
We are also given the points:
(-4, 11) = (x, y)
Using the distance formula at points (x, y):
distance = | -2 * -4 + 1 * 11 + -4 | / sqrt [(- 2)^2 + (1)^2]
distance = 15 / sqrt (5)
distance = 6.7
So the tree is about 6.7 ft away from the zip line.
The question is an illustration of distance between a point and a line.
The distance between the zip line and the tree is 6.70 feet
The zip line equation is given as:
[tex]\mathbf{y = 2x +4}[/tex]
The coordinates of the tree is given as:
[tex]\mathbf{(x,y) = (-4,11)}[/tex]
The distance (d) between an equation and a point is:
[tex]\mathbf{d = \frac{|ax + by + c|}{\sqrt{a^2 + b^2}}}[/tex]
Where:
[tex]\mathbf{ax +by + c = 0}[/tex]
Rewrite [tex]\mathbf{y = 2x +4}[/tex] as [tex]\mathbf{ax +by + c = 0}[/tex]
[tex]\mathbf{2x - y + 4 = 0}[/tex]
By comparison:
[tex]\mathbf{a =2, b = -1, c = 4}[/tex] and [tex]\mathbf{(x,y) = (-4,11)}[/tex]
So, we have:
[tex]\mathbf{d = \frac{|2 \times -4 -1 \times 11 + 4|}{\sqrt{(2)^2 + (-1)^2}}}[/tex]
[tex]\mathbf{d = \frac{|-15|}{\sqrt{5}}}[/tex]
Evaluate square root
[tex]\mathbf{d = \frac{|-15|}{2.24}}[/tex]
Remove absolute bracket
[tex]\mathbf{d = \frac{15}{2.24}}[/tex]
[tex]\mathbf{d = 6.70}[/tex]
Hence, the distance between the zip line and the tree is approximately 6.70 feet

octagon ABCDEFGH was dilated by a scale factor of 2. Therefore, option 2 is the correct answer.
To find the scale factor by which octagon ABCDEFGH was dilated, we can compare the corresponding side lengths of the original octagon and the dilated octagon.
Let's take one side, for example, side AB. The length of side AB in the original octagon is the distance between points A(3, 1) and B(3, -1), which is 2 units.
The length of side A'B' in the dilated octagon is the distance between points A'(6, 2) and B'(6, -2), which is also 4 units.
By comparing the side lengths, we can see that side A'B' is twice as long as side AB.
Therefore, the scale factor by which octagon ABCDEFGH was dilated is 2.
In conclusion, octagon ABCDEFGH was dilated by a scale factor of 2.
Therefore, option 2 is the correct answer.
The octagon ABCDEFGH was dilated by a scale factor of 2. This means each coordinate in the original octagon was multiplied by 2 to obtain the corresponding point in A'B'C'D'E'F'G'H'.
The scale factor of dilation between octagon ABCDEFGH and its dilated counterpart A'B'C'D'E'F'G'H' can be determined by comparing corresponding side lengths. Taking one side as an example, the original octagon has a side connecting points A(3, 1) and B(3, -1) with a length of 2 units (vertical distance). In the dilated octagon, the corresponding side connecting A'(6, 2) and B'(6, -2) has a length of 4 units (vertical distance). The scale factor (k) is then calculated as the ratio of the length in the dilated octagon to the length in the original octagon: [tex]\( k = \frac{4}{2} = 2 \)[/tex].
Therefore, octagon ABCDEFGH was dilated by a scale factor of 2 from its original position to A'B'C'D'E'F'G'H'. This indicates that the coordinates of each point in the original octagon were multiplied by 2 to obtain the corresponding points in the dilated octagon. The scale factor, in this case, is 2, signifying a doubling in size during the dilation process.

A clothing store is running a special in which customers receive a free pair of jeans with the purchase of 4 shirts. It costs the clothing company $3.46 to produce one shirt and $5.56 to produce one pair of jeans. The store is selling each shirt for $21.46. Approximately how much money will the company make if 42 customers take advantage of the special?
The clothing company will make approximately $214.60 if 42 customers take advantage of the special.
Explanation:To calculate the amount of money the company will make, we need to determine the total cost of shirts and jeans given out for free.
Each customer will receive a free pair of jeans for every 4 shirts purchased.
The cost of 1 shirt is $3.46 and the cost of 1 pair of jeans is $5.56.
So, the cost of 4 shirts is 4 x $3.46 = $13.84.
Therefore, for each set of 4 shirts, the company is losing $13.84 on production costs and gaining $21.46 on sales.
For 42 customers, the company will distribute 10 sets of 4 shirts and give away 10 pairs of jeans.
The total amount of money the company will make is (10 x $21.46) = $214.60.
