The cost of the circular floor is $3299.77.
The space a circle takes up in a two-dimensional plane is known as the area of the circle.
For measuring the area occupied by a circular field or plot, use the area of a circle formula. The area formula will allow us to determine how much cloth is required to completely cover a circular table, for example.
Area of circle = [tex]\pi r^{2}[/tex]
Given in question,
[tex]\pi[/tex] = 3.14
Diameter = 33
Radius = Diameter/2
= 33/2
= 16.5
Area = 3.14*16.5*16.5
= 854.865 square
Cost per square = $3.86
Cost for 854.865 square = 3.86*854.865
= 3299.78

You deposit $6000 in an account earning 4% interest compounded monthly. How much will you have in the account in 5 years??
Only answer if you know ! Any other answers will be reported.
$7325.98 is the amount you have in the account in 5 years
How to calculate how much will you have in the account in 5 years?
Compound interest is the interest determined on the principal and the interest accumulated over the previous period.
Given that: You deposit $6000 in an account earning 4% interest compounded monthly.
Amount (A) = P(1+r)^t
Where P is the principal, r is the interest rate and t is the time
P = $6000, r = 4% / year = 4/12 = 1/3 % / month = 1/300 , t = 5 years = 5×12 = 60 months
A = P(1+r)^t
A = 6000(1 + 1/300)⁶⁰
A = $7325.98
Thus, you will have $7325.98 in the account in 5 years

The x-intercept of the linear equation is (7, 0).
How to find the x-intercept of the linear function?Here we have the following linear equation:
y = x - 7
We want to find the x-intercept, this is the point where the line intercepts the x-axis, it will happen when we take the value of y = 0, then we need to solve.
0 = x - 7
Solving that, we get:

Answer:
X=8, y=19
Step-by-step explanation:
These two triangles are congruent. This means that angle STR = angle MNL, so angle STR = 63°. We know the angles in a triangle must sum to 180°, so we can figure out 3x from this, given that we know the other two angles. 63 + 93 = 156, so 3x = 180-156=24. This gives us that x = 8. Now we can solve for x, because we know that SR = ML, so 3x + y = 43. We know x = 8, so we get that 24 + y = 43, or y = 19.

The diagonal distance across the plaza is 70.7 meters
Given,
In the question:
Elise walks diagonally from one corner of a square plaza to another.
Each side of the plaza is 50meters.
To find the diagonal distance across the plaza.
Now, According to the question:
We have been given that Elise walks diagonally from one corner of a square plaza to another. Each side of the plaza is 50 meters.
Since we know that diagonal of a square is product of side length of square and [tex]\sqrt{2}[/tex]. So we will find diagonal of our given square plaza by multiplying 50 by [tex]\sqrt{2}[/tex] .
Diagonal distance across the plaza = 50 x [tex]\sqrt{2}[/tex] .
We know that the value of [tex]\sqrt{2}[/tex] = 1.41421
Diagonal distance across the plaza = 50 x 1.41421
Diagonal distance across the plaza = 70.7105 ≈ 70.7

The enrollment for a school in 2010 was 1510 students. In 2020, the enrollment was 860 students. Find and interpret the rate of change in enrollment from 2010 to 2020.
Answer:
Step-by-step explanation:
The rate of change is the slope of the line formed by connecting the two data points:
1. (2010,1510). and [enrollment for a school in 2010 was 1510 students]
2. (2020, 860) [In 2020, the enrollment was 860 students]
Slope is the Rise/Run of the line. Lets go from the first point to the second.
The Rise: (1510 - 860) = 650
The Run: (2020-2010) = 10
The slope, or rate of change, is = 65
The interpretation is that "The enrollment at the school increase by an average of 65 students every year since 2010 until 2020."

8x + 38 = -3(-6 - 4x)
Answer:
x=5
Step-by-step explanation:
step one: distribute to get rid of parentheses. this means multiplying -3 by the numbers inside of the parentheses next to it.
-3(-6)= 18 and -3(-4x)=12x
this makes the equation now 8x+38=18+12x
step two: move x to one side of the equation. we can do this by using inverse operations, so we're going to subtract 8x from both sides.
8x-8x=0, 12x-8x= 4x.
this makes the equation now 38=18+4x
step three: isolate x. this means getting rid of the 18. to do this, we are going to use inverse operations again. this means subtracting 18 from both sides.
18-18=0, 38-18=20.
this makes the equation now 20=4x
step four: divide to get x by itself. we don't want to know what 4x is, we just want to know what plain x is. so we're going to use inverse operations for the last time and divide both sides by 4 because 4x is the same thing as saying "four times x"
20/4= 5, 4x/4=x
this makes the equation now 5=x
that's your answer, x=5. hope this helped!

What is Linear Pair?
A linear pair is a pair of adjacent angles that are supplementary, meaning they add up to equal 180 degrees. Linear pairs can be found in many shapes and geometric shapes, such as squares, rectangles, and parallelograms. Linear pairs can also be found in the angles of intersecting lines. When two lines intersect, four angles are formed, and two of them will always form a linear pair. Linear pairs can also be found in circles, as the angles formed by two chords that intersect with each other will always form a linear pair.
