Here is a diagram of a softball field:
Outfield
Infield
110 ft
250 ft
Use this diagram to answer the questions below.
Use 3.14 to represent and round your answer to the nearest whole number. Type your answers in the boxes below.
HINT: For this problem we are going to assume the infield is a regular circle. Solve as if it is a circle.
1. The fence around the field (the whole perimeter of the shape) is about
feet
2. The area of the outfield is about
ft
a. The Length of the fence around the field = perimeter of quarter circle is 892.7 ft.
b. The area of the outfield is 39,584 sq. ft..
What is the circle about?Note that:
Perimeter of circle = 2πrPerimeter of a quarter circle = 2r + 1/4(2πr).a. The length of the fence around the field = perimeter of the quarter circle fence
= 2r + 1/4(2πr).
r = 250 ft
Put in the value
The length of the fence around the field = 2(250) + 1/4(2 × π × 250)
= 892.7 ft.
b. Size of the outfield = area of the full field (quarter circle) - area of the infield (cicle)
= 1/4(πR²) - πr²
R = radius of the full field = 250 ft
r = radius of the infield = 110/2 = 55 ft
Put in the values
Size of the outfield = 1/4(π × 250²) - π × 55²
= 49,087 - 9,503
= 39,584 sq. ft.

2. You need to work a total of 44 hours per week at your two jobs. Your job as a store clerk pays
$5.50 an hour, and your job as a landscaper pays $6.00 an hour. You need to earn $250.00 per
week to cover your expenses. Which system of equations shows the various numbers of hours
you can work at each job? C is the number of hours worked as a clerk, while L is the number of
hours worked as a landscaper.
A.
C +L = 44
5.50C + 6L = 250
B.
C + L = 250
5.50C + 6L = 44
C.
5.50C + L = 44
C + 6L = 250
D.
C + L = 44
6C + 5.50L = 250
The equation shows the various numbers of hours you can work at each job are 5.50C + 6L = 250, and C + L = 44, so option A is correct.
What is the equation?Equation: A declaration that two expressions with variables or integers are equal. In essence, equations are questions and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics.
Given:
You work a total of 44 hours per week at your two jobs, Your job as a store clerk pays $5.50 an hour, and your job as a landscaper pays $6.00 an hour, and the total money to be earned is $250 per week.
Calculate the equation as shown below,
5.50C + 6L = 250 and C + L = 44
Solve the above equation by using the elimination method,
C = 28 hours and L = 44 - 28 = 16 hrs
Therefore, the equation shows the various numbers of hours you can work at each job are 5.50C + 6L = 250, and C + L = 44.

Determine which of following points lie in the solution set of the inequality y >= 2x-4 and which do not. Justify each choice.
a) (5,4)
b) (0,1)
c) (10,16)
d) (2,-1)
The points lie on the given inequality y ≥ 2x-4 are (0,1) and (10,16)
What is inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given that an inequality y ≥ 2x-4
We need to check whether the given points lie on the solution of the inequality or not,
1) (5, 4)
Put x = 5
2×5-4 = 10-4 = 6
4 ≥ 6, this is a contradiction which means (5, 4) do not lie on the solution,
2) (0, 1)
Put x = 0
2×0 - 4 = 0-4 = -4
1 ≥ -4, satisfying the condition hence lies on the solution.
3) (10, 16)
Put x = 10
2×10-4 = 20-4 = 16
16 = 16. satisfying the condition hence lies on the solution.
4) (2, -1)
Put x = 2,
2×2-4 = 4-4 = 0
-1 ≥ 0, this is a contradiction which means (5, 4) do not lie on the solution,
Hence, points lie in the solution set of the inequality are (0,1) and (10,16)

If each interior angle of a regular polygon measures 120 , how many sides does the polygon have?
Answer:
the ans is 6 sides i guess
[tex]\huge\sf{Answer :- }[/tex]
Given :- Each interior angle of regular polygon is 120°To Find :- Number of sides of the polygon Formula :-Interior angle of the polygon = [180(n - 2)]/n
where,
n = sides of the polygonSolution :-Let, The number of sides of polygon be n
By substituting values according to the formula,➯ [180(n - 2)]/n = 120°
➯ 180n - 360 = 120n
➯ 180n - 120n = 360
➯ 60n = 360
➯ n = 360/60
➠ n = 6
Hence, The regular polygon have 6 sidesThomas has $10 to spend on lunch he decides to buy some chicken sandwiches which cost $2.75 each and one container of orange juice which cost $1.50 what is the maximum Number of chicken sandwiches Thomas can buy

use the chain rule to calculate y = (2u² + 3)⅓ and u = √(2x +1)
full method
Answer:
Given the reference to the chain rule, I assuming by "calculate", you mean "take the derivative of", in which case we have:
For the first function:
[tex]y = (2u^2 + 3)^{\frac{1}{3}}\\\\\frac{dy}{du} = \frac{1}{3}(2u^2 + 3)^\frac{-2}{3}(4u)\\\\\frac{dy}{du} = \frac{4u}{3}(2u^2 + 3)^\frac{-2}{3}\\\\\frac{dy}{du} = \frac{4u}{3(2u^2 + 3)^\frac{2}{3}}[/tex]
and for the second one:
[tex]u = \sqrt{2x + 1}\\\\u = (2x + 1)^{0.5}\\\\\frac{du}{dx} = 0.5(2x + 1)^{-0.5}(2)\\\\\frac{du}{dx} = \frac{1}{\sqrt{2x + 1}}[/tex]
