A pizza slice is in the shape of a circular sector OAB, with the central angle 0 = 50 deg and a radius of 7cm. 0 A B В Find the perimeter of the pizza slice. (no answer)
Answer:
The perimeter of the pizza slice is 20.1 cm
Step-by-step explanation:
Perimeter of a Sector of a Circle
The arc length of a sector of a circle of radius r and angle θ is given by:
L = rθ
The angle must be expressed in radians.
The total perimeter of the circular sector, including the two radii, is:
P = rθ + 2r
The pizza slice has a radius of r=7 cm and a central angle of θ=50°
Converting to radians:
[tex]\theta=50*\frac{\pi}{180}=\frac{5\pi}{18}[/tex]
The perimeter is:
[tex]P = 7*\frac{5\pi}{18} + 2*7[/tex]
Calculating:
P = 20.1 cm
The perimeter of the pizza slice is 20.1 cm

How many solutions does 2x-4=4-2x have?
Answer:
8/4 or 2
Step-by-step explanation:
2 solutions
The equation 2x - 4 = 4 - 2x has a single solution, x = 2.
The equation 2x - 4 = 4 - 2x can be simplified and analyzed to determine the number of solutions.
First, let's simplify the equation by combining like terms:
4x - 4 = 4
Next, we can add 4 to both sides of the equation to isolate the variable:
4x - 4 + 4 = 4 + 4
This simplifies to:
4x = 8
Now, we divide both sides of the equation by 4 to solve for x:
(4x) / 4 = 8 / 4
This yields:
x = 2
Therefore, the equation 2x - 4 = 4 - 2x has a single solution, x = 2.
This means that when we substitute x = 2 into the original equation, both sides will be equal. Thus, the equation has a unique solution, indicating that the two sides of the equation represent the same line or point of intersection.
In summary, the equation has one solution, which is x = 2.

Two families went to Rollercoaster World.
The Brown family paid $170 for 3 children and 2 adults.
The Peckham family paid $360 for 4 children and 6 adults.
If \displaystyle xx is the price of a child ticket in dollars and \displaystyle yy is the price of an adult ticket in dollars, write a system of equations that models this situation and then solve it to find out how much each type of ticket costs.
Answer:
Children ticket cost $30 and adult ticket costs $40.
Step-by-step explanation:
Given that:
x = price of a child ticket
y = price of an adult ticket
According to given statement;
3x+2y=170 Eqn 1
4x+6y=360 Eqn 2
Multiplying Eqn 1 by 3
3(3x+2y=170)
9x+6y=510 Eqn 3
Subtracting Eqn 2 from Eqn 3
(9x+6y)-(4x+6y)=510-360
9x+6y-4x-6y=150
5x=150
Dividing both sides by 5
[tex]\frac{5x}{5}=\frac{150}{5}\\x=30[/tex]
Putting x=30 in Eqn 1
3(30)+2y=170
90+2y=170
2y = 170-90
2y = 80
Dividing both sides by 2
[tex]\frac{2y}{2}=\frac{80}{2}\\y=40[/tex]
Hence,
Children ticket cost $30 and adult ticket costs $40.

A student was selected as a captain of a cooking team in a consumer and family studies class. The student could pick 2 of 5 girls and 3 of 7 boys to be on their team. What is the total number of different teams that this captain could select?
Answer:
This captain could select 350 different teams.
Step-by-step explanation:
The order in which the girls and the boys are picked is not important. For example, picking Daniela and Laura is the same as picking Laura and Daniela. So we use the combinations formula to solve this question.
Combinations Formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Girls:
2 from a set of 5. So
[tex]C_{5,2} = \frac{5!}{2!(5-2)!} = 10[/tex]
Boys:
3 from a set of 7. So
[tex]C_{7,3} = \frac{7!}{3!(7-3)!} = 35[/tex]
Total:
[tex]10*35 = 350[/tex]
This captain could select 350 different teams.

Answer:
The Missing Angle is 35°
Step-by-step explanation:
Given :-
∠ DFE = 65° , ∠ RDE = 100°To Find :-
∠ DEF (?)Solution :-
We know that angle made by a straight line is 180°So ,
∠ RDE + ∠ FDE = 180°
100° + ∠ FDE = 180°
∠ FDE = 80°
The sum of all angles in a triangle is 180°
Therefore ,
∠ DEF + ∠ DFE + ∠FDE = 180°
∠ DEF + 65° + 80° = 180°
∠ DEF = 35°
