The length of the park not counting the path is 98 yards
How to determine the length of the park
The formula for determining the area of a rectangle is expressed as;
Area = lw
Where;
l is the length of the rectanglew is the width of the rectangleFrom the information given, we have that;
The dimensions of the path having a width of 1 yard path around it are
(L+2) x (W+2)
We have to add 2 to the length and width because there will be a 1 yard path on all 4 sides of the rectangle
Given that the area is 4200 square yards; the original width is 40 yards
Now, substitute the values into the formula, we have;
Since Area = LW
4200 = (L+2)(W+2)
4200 = (L+2)(40+2)
Add the values
4200 = (L+2)(42)
expand the bracket
4200 = 42L + 84
collect like terms
4116 = 42L
Make 'L' the subject of formula
L = 98 yards
Hence, the length is 98 yards

What is an algebraic expression?An algebraic expression is simply seen as one with terms, factors, variables, coefficients, constants.
These expressions may also consist of arithmetic operations, some of which includes;
AdditionDivisionSubtractionMultiplicationBracketParentheses, among others.Based on the information given, we have;
−0.28x − 15.3 = 1.92
To determine the value of the variable 'x' we need to take the following steps;
collect like terms from the equation
-0. 28x = 1. 92 + 15. 3
Add like terms
-0. 28x = 17.22
Divide both side by the coefficient of x
x = 17. 22/-0.28
x = - 61. 5

We would like to estimate the proportion of uf students who owns a scooter to within 1% of the truth, with 95% confidence. We believe around 20% of students do. How many students should be sampled?.
It is determined that 188 students should be sampled to use the confidence interval for a proportion.
What is mean by the term confidence interval?A confidence interval is indeed the mean of the estimate plus and minus its variation.We get the very next confidence interval of percentages in a sample of n people surveyed with a success probability of π and a confidence level of.π ± z√π(1-π)/n
In which case,
z is indeed the z-score with the p-value of 1+α/2
The error margin is as follows:
M = z√π(1-π)/n
In this case:
z does have a p-value of at 95% confidence, so z = 1.96.Thus p = 0.2, a 20% estimate.Taking into account, this same sample size is n. M = 0.02.Then:
M = z√π(1-π)/n
0.02 = 1.96√0.02(1-0.02)/n
√n = 13.72
n = 188.23
To summarize:
A total of 188 students must be sampled to estimate the proportion of of students who owns a scooter.

A bag of fertilizer that weighs 18 3/4 pounds can cover 5000 square feet. how many pounds of fertilizer will be needed to cover 27,000 square feet? how many bags of fertilizer are needed?
We know how many pounds are needed to cover 5000 ft^2, and we need to find how many are needed to cover 27000ft^2. To find this value, divide 27000 by 5000 and multiply the result by the weight.
27000/5000 x 18.75
5.4 x 18.75
101.25
So, we need 101 1/4 pounds of fertilizer. How many bags is that?
101.25/18.75
5.4
We'll say that since the 0.4 of a bag will still need to be used, that you need 6 bags to cover 27000ft^2.
If I rotated Block C by 90 degrees clockwise where would it be?
After the 90° rotation, Block C will resemble this in some ways (see the image below).
What is rotation?The concept of rotation in mathematics has its roots in geometry. Any rotation is a movement of a specific area while maintaining at least one point. It may be used to describe, for instance, how a rigid body moves around a fixed point. As an example of rotation in the real world, we know that the earth revolves around its own axis. A group of people walking in a circle while holding hands and rotating either clockwise or counterclockwise.So, rotate block C by 90°:
Block C will look somewhat like this (Refer to the image attached below) after the rotation of 90°.

The months will they have same number of miles. is 1.732 months.
How to illustrate the information!Miranda's used car has 5,132 miles on it already, and she drives 525 miles per month. This will be expressed as y = 5132 + 525x
Lily's car has 4,789 miles on it already, and she drives 723 mile per month. This will be:
y = 4789 + 723x
x = number of months
y = miles
The number of months will be gotten by equating the equations. This will be:
5132 + 525x = 4789 + 723x
Collect like terms
198x = 343

The distance of a golf ball from the hole can be represented by the right side of a parabola with vertex (-1,8). The ball reaches the hole 1 second after it is hit. What is the equation of the parabola, in vertex form, that represents the ball's distance, y, from the hole, x seconds after the ball is hit?
The equation of the parabola, in vertex form, that represents the ball's distance, y, from the hole, x seconds after the ball is hit is
y = (-2m/s²)t² + (-2m/s)t + 6m.
Given:
Let's assume that the hole is at y = 0m, with x seconds as the time.
The vertex of the parabola can be written as (-1s, 8m) where the time variable, x, is supposed to be in seconds, while the distance variable, y, is supposed to be in meters.
The ball reaches the hole at x = 1s, so we have point (1s, 0m)
The vertex of the parabola y = ax² + bx + c is known to be at
x = -b/2a,
So, -1 = -b/2a
We have the following equations,
8m = a(-1s)² + b(-1s) + c
0m = a*(1s)² + b(1s) + c
-1s = -b/2a
b = 2a × 1s
Substituting the value of b in the equations and simplifying them,
8m = a×1s² - 1s×2a×1s + c
⇒ 8m = a( 1s² - 2s²) + c = -a×1s² + c.
0m = a×1s² + 1s×2a×1s + c
⇒ 0m = a(1s² + 2s²) + c = a×3s² + c
Deriving the value of c from the second equation we put it in the first equation,
c = - a×3s²
The first equation is as,
8m = -a×1s² - a×3s² = -a×4s²
a = 8m/-4s² = -2m/s²
From the value of a we can calculate the values of b and c.
c = -a×3s² = -(-2m/s²)×3s²= 6m.
b = 1s×2a = 1s×(-2m/s²) = -2m/s.
Then the equation is:
y = (-2m/s²)t² + (-2m/s)t + 6m

Under her cell phone plan, Mei Mei pays a flat cost of $46 per month and $5 per
gigabyte. She wants to keep her bill under $70 per month. Write and solve an
inequality which can be used to determine g, the number of gigabytes Mei Mei can
use while staying within her budget.
The flat cost of the plan = is $46 per month
Cost per gigabyte = $5 per gigabyte
Number of gigabytes = g
The maximum amount Mei Mei wants to spend on the bill = is $70 per month,
So, for each month,
$46 + $5(g) < $70
⇒ $5(g) < $70 - $46
⇒ $5(g) < $24
⇒ g < $24/$5
⇒ g < 4.8
The number of gigabytes to be used per month should be less than or equal to 4.8.

assuming
length 1 = AB = 3 cm
length 2 = 5.8 / 2
length 3 = 4.2 / 2
Reason for length 2 and length 3 is when the diagonal of a parallelogram intersect they bisect each other. bisect means divide each other into two equal parts
substituting the values
perimeter of the triangle = 3 + 5.8 / 2 + 4.2 / 2
