Answer:

The Missing Angle is 35°

Step-by-step explanation:

Given :-

To Find :-

Solution :-

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°

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

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:

Answer:

I think its uh

Step-by-step explanation:

the first= it is. f= 3x+3/x^2

the second= it is. f= x-3/x^2

sorry if this is wrong btw, i tried my best U-U

Answer:

they're not inverses.

Step-by-step explanation:

the inverse of f(x)= 3/x +3 would be f(x) 3 / x-3

for the second equation the inverse of that one would be h(x) = -3/ x-1

i hope this helps.

Answer:

Therefore, the total Resistance:  R = 93.9 Ω

Step-by-step explanation:

Given

R₁ = 1 × 10²

R₂ = 2.5 kΩ = 2.5 × 10³ Ω

R₃ = 4  kΩ = 4 × 10³ Ω

Given that the given resisters are connected parallel, so using the formula to calculate the total Resistance R:

[tex]\frac{1}{R}\:=\:\frac{1}{R_1}\:+\:\frac{1}{R_2}+\frac{1}{R_3}[/tex]

susbtituting R₁ = 1 × 10², R₂ = 2.5 × 10³ Ω, and R₃ = 4 × 10³ Ω

[tex]\frac{1}{R}=\frac{1}{1\times \:10^2}+\frac{1}{2.5\times \:10^3}+\frac{1}{4\times \:10^3}[/tex]

Multiply by LCM of R, 100, 2500, and 4000:   20000 R

[tex]\frac{1}{R}\cdot \:20000R=\frac{1}{1\cdot \:10^2}\cdot \:20000R+\frac{1}{2.5\cdot \:10^3}\cdot \:20000R+\frac{1}{4\cdot \:10^3}\cdot \:20000R[/tex]

simplify

[tex]20000=213R[/tex]

Switch sides

[tex]213R=20000[/tex]

Divide both sides by 213

[tex]\frac{213R}{213}=\frac{20000}{213}[/tex]

Simplify

[tex]R=\frac{20000}{213}[/tex]

[tex]R = 93.9[/tex] Ω

Therefore, the total Resistance:  R = 93.9 Ω
