Find the area of the shaded sector. PLZ HELP!:)
Answers
Answer:
Area of whole circle, i.e. 360 degrees = π(8.91)(8.91) = 79.3881 sq. cm
Area of 1 degree = 0.2205225 sq.cm.
Area of 81 degrees = 17.8623225 sq.cm.
The area of the shaded sector is about 16.77 cm2.
We are given that;
The radius=8.91
Now,
Surface area are derived for some standard shapes like circle, triangle, parallelogram, rectangle, trapezoid, etc.
When some shape comes which isn't standard figure, then we find its area by slicing it (virtually, like by drawing lines) in standard shapes. Then we calculate those composing shapes' area and sum them all.
Thus, we have:
[tex]\text{Area of composite figure} = \sum (\text{Area of composing figures})[/tex]
That ∑ sign shows "sum"
To find the area of the shaded sector, we need to use the formula:
[tex]$A = \frac{\theta}{360} \times \pi r^2$[/tex]
where [tex]\theta[/tex] is the central angle in degrees, and r is the radius of the circle.
Plugging in the given values, we get:
[tex]$A = \frac{81}{360} \times \pi (8.91)^2A \approx 16.77 \text{ cm}^2$[/tex]
Therefore, by the area answer will be 16.77 cm2.

A company has a $150 budget to provide lunch for its 20 employees. The options are to provide either roast beef sandwiches, which cost $5 apiece, or tuna sandwiches, which also cost $5 apiece. The company also wants to use the entire budget. Suppose r represents the number of roast beef sandwiches it provides and t represents the number of tuna sandwiches. Which statement is correct?
The company can provide lunch for all 20 employees and use the entire budget because there is a solution to the system of equations r minus t = 20 and 5 r + 5 t = 150.
The company can provide lunch for all 20 employees and use the entire budget because there is a solution to the system of equations r + t = 20 and 5 r + 5 t = 150.
The company cannot provide lunch for all 20 employees and use the entire budget because there is no solution to the system of equations r minus t = 20 and 5 r + 5 t = 150.
The company cannot provide lunch for all 20 employees and use the entire budget because there is no solution to the system of equations r + t = 20 and 5 r + 5 t = 150.
Answers
Answer:
D.) The company cannot provide lunch for all 20 employees and use the entire budget because there is no solution to the system of equations r+t=20 and 5r+5t=150
Step-by-step explanation:
The given information says that the total amount of lunch bought should equal $150 when both options cost $5:
[tex]5r+5t=150[/tex]
It also says that the food should feed all 20 employees:
[tex]r+t=20[/tex]
This is now a system. Solve by substitution.
Solve the second equation for r. Use inverse operations to isolate the variable by subtracting t from both sides:
[tex]r+t-t=20-t\\\\r=20-t[/tex]
Now insert this value of r into the first equation:
[tex]5(20-t)+5t=150[/tex]
Simplify the equation. Use the distributive property:
[tex]5(20)+5(-t)+5t=150\\\\100-5t+5t=150[/tex]
Cancel the terms:
[tex]100\neq 150[/tex]
100 does not equal 150, so there is no solution to the system.

The width of a rectangle is 3 cm less than twice its length. If the perimeter of the
rectangle is 18 cm, find its dimensions.
Answers
Answer:
length=4
Width=2×4-3=5
Step-by-step explanation:
Let length =X
Width =2x-3
Perimeter=18
2(length+width)=18
2(X+2x-3)=18
3x-3=9
3x=12
X=12/3
X=4
So length=4
Width=2×4-3=5
Answer:
[tex] \huge{ \boxed{ \bold{ \sf{Length \: = \: 4 \: cm}}}}[/tex]
[tex] \huge{ \boxed{ \bold{ \sf{Width = 5 \: cm}}}}[/tex]

☯ Question :
The width of a rectangle is 3 cm less than twice its length. If the perimeter of the rectangle is 18 cm, find its dimensions.☯ Step - by - step explanation :
✒ First, Let length of a rectangle be ' L '.
✑ Given :
Width of a rectangle = 3 cm less than twice its length ( i.e W = 2L - 3 )Perimeter of a rectangle ( P ) = 18 cm☞ Finding value of length of a rectangle :
[tex] \boxed{ \sf{Perimeter \: of \: a \: rectangle = 2(L + W)}}[/tex]
Plug the values and solve for L
➺ [tex] \sf{18 = 2(L+ 2L - 3)}[/tex]
➺ [tex] \sf{18 = 2(3L - 3)}[/tex] { Add : 2L and L )
➺ [tex] \sf{18 = 6L - 6}[/tex] { Distribute 2 through the parentheses )
➺ [tex] \sf{6L - 6 = 18}[/tex] { Swipe the sides of the equation }
➺ [tex] \sf{6L = 18 + 6}[/tex] { Move 6 to right hand side and change it's sign )
➺ [tex] \sf{6L = 24}[/tex] { Add the numbers : 18 and 6 }
➺ [tex] \sf{ \frac{6L}{6} = \frac{24}{6}} [/tex] { Divide both sides by 6 }
➺ [tex] \boxed{ \sf{length \: ( \: L\: ) \: = \: 4 \: cm}}[/tex]
☞ Now , Evaluating 2L - 3 when L = 4 cm in order to find the value of width of a rectangle : [tex] \sf{2l - 3}[/tex]
➺ [tex] \sf{2 \times 4 - 3}[/tex] { Plug the value of length }
➺ [tex] \sf{8 - 3}[/tex] { Multiply 2 by 4 }
➺ [tex] \boxed{ \sf{Width \: ( \: W \: ) \: = \: 5 \: cm}}[/tex]
Hence ,
Length of a rectangle ( L ) = 4 cmWidth of a rectangle ( W ) = 5 cmHope I helped!

[tex]x^2+5x+6[/tex]
Break the expression into the groups

What is the description of the inequality?The values that are less than a number a in the number line are the values to the left of a.
Hence, for the inequality x < 1, we have that:
All the points to the left of x = 1 are part of the solution
Additionally, since the inequality signal is < and not ≤ 1, x = 1 is not part of the inequality, meaning that there is an open interval at x = 1.
