The observation deck of a building forms a sector with the dimensions shown.
Isafety rail
10 yd
10 yd
Find the length of the safety rail and the area of the deck. Round your answers to the nearest tenth.
The length of the safety rail is about
yards.
The area of the deck is about
square yards.
1. The length of the safety rail = Arc length is: 15.7 yd
2. The area of the deck = area of sector is: 78.5 yd²
What is the Area of a Sector?Area of sector = ∅/360 × πr²
What is the Length of an Arc?Arc length = ∅/360 × 2πr
1. Length of the safety rail = Arc length = ∅/360 × 2πr
= 90/360 × 2π(10)
= 15.7 yd
2. Area of the deck = area of sector = ∅/360 × πr²
= 90/360 × π(10²)
= 78.5 yd²

solve the following system of equations algebraically please ty
Eliminating y right away is easiest. Add -3(equation 1) to equation 2, and add 3(equation 3) to equation 2:
-3(2x + y + 3z) + (-3x + 3y - 2z) = -3(3) + (-8)
-6x - 3y - 9z - 3x + 3y - 2z = -9 - 8
-9x - 11z = -17
9x + 11z = 17 [equation 1]
3(5x - y + 5z) + (-3x + 3y - 2z) = 3(13) + (-8)
15x - 3y + 15z - 3x + 3y - 2z = 39 - 8
12x + 13z = 31 [equation 2]
Eliminating x next is easier than eliminating z. Add -4(equation 1) to 3(equation 2):
-4(9x + 11z) + 3(12x + 13z) = -4(17) + 3(31)
-36x - 44z + 36x + 39z = -68 + 93
-5z = 25
z = 25/(-5)
z = -5
Plug this into either of the previous equations and solve for x :
9x + 11z = 17
9x + 11(-5) = 17
9x - 55 = 17
9x = 72
x = 72/9
x = 8
Plug x and z into any of the 3 original equations and solve for y :
2x + y + 3z = 3
2(8) + y + 3(-5) = 3
16 + y - 15 = 3
1 + y = 3
y = 2

M is directly proportional to L^3
When L = 2, M= 160
Find the value of M when L = 3
Answer:
2,160
Step-by-step explanation: since M is proportional to L^3 so when L=2 then L^3=8 so M=160 which means if L = 3
When L = 3, the value of M is 540. The relationship between M and L³ holds true.
When two variables, M and L, are directly proportional, it means that their ratio remains constant.
In this case, M is directly proportional to L³, which can be written as M = k × L³, where k is the constant of proportionality.
To find the value of k, we can use the given information when L = 2, and M = 160:
160 = k × 2³
160 = k × 8
k = 160 / 8
k = 20
Now that we have the value of k, we can find the value of M when L = 3:
M = 20 × 3³
M = 20 × 27
M = 540
So, when L = 3, the value of M is 540. The relationship between M and L³ holds true for any value of L when multiplied by the constant of proportionality k, which we found to be 20 in this case.

A rectangle’s perimeter and its area have the same numerical value. The length of the rectangle is 6. What is the width of the rectangle in units?.
Answer:
Step-by-step explanation:
Formula
P = 2*w + 2*L
Area = L*w
Givens
Area = P
L = 6
Create equation and Solve
LW = 2w + 2L
6w = 2w + 2*6
6w = 2w + 12 Subtract 2w from both sides
6w - 2w = 12 Combine
4w = 12 Divide by 4
4w/4 = 12/4
w = 3
Check
Area = 6*3 = 18
Perimeter = 2*3 + 2*6
Perimeter = 6 + 12 Combine
Perimeter = 18
It does check.
