What is the area of the shaded region below?
с
90°
А
B
12 cm
Answers
Answer:
≈ 41.1 cm²
Step-by-step explanation:
The shaded area (A) is calculated as
A = area of sector - area of Δ ABC
= πr² × [tex]\frac{90}{360}[/tex] - ( [tex]\frac{1}{2}[/tex] × 12 × 12 )
= π × 12² × [tex]\frac{1}{4}[/tex] - (6 × 12)
= 144π × [tex]\frac{1}{4}[/tex] - 72
= 36π - 72
≈ 41.1 cm² ( to 1 dec. place )
Find the value of x if the measure of angle 1 = 11x - 9 and the measure of angle 5 = 7x + 9
Answers
Answer:
x = 10
Step-by-step explanation:
Lett angle 1 and angle 5 lie on the same straight line. This shows that they are supplementary
Hence;
<1 + <5 = 180
11x - 9 + 7x + 9 = 180
18x = 180
x = 180/18
x = 10
Hence the value of x is 10

1. find the exact value of cos2θ if sin 2θ=3/4 and θ is between 0° and 90°
2. verify that sinθ(cos²θ-cos2θ)=sin³θ
Answers
Answer:
Identities used:
sin²θ + cos²θ = 1cos2θ = cos²θ - sin²θ#1
sin2θ = 3/4, and θ in the first quadrantcos²2θ = 1 - sin²2θcos2θ = √(1 - sin²2θ) = √(1 - 9/16) = √(7/16) = √7 / 4#2
sinθ(cos²θ - cos2θ) = sinθ(cos²θ - (cos²θ - sin²θ) = sinθ(sin²θ) = sin³θWhat is the inverse of addition

The diameter of a planet is about 25,660 mi. The diameter of the planet's moon is about 35% of the diameter of the planet. What percent of the volume of the planet is the volume of its moon?
The volume of the planet's moon is % of the volume of its planet.
(Round to the nearest whole number as needed.)
Answers
Answer:
4%
Step-by-step explanation:
Volume of sphere
v = (4/3)πr^3
Volume moon/ volume planet
We don't actually need the numeric value of the radius
just the 35% ratio
Radius of moon = .35 radius of planet
Vm/ Vp = (4/3)π(.35r)^3 / (4/3)π(r)^3
Cancel like terms
Vm / Vp = .35^3
Vm / Vp = 0.042875
Expressed as a percentage
Vm / Vp = 4.2875%
Rounded
Vm / Vp = 4%

A construction company is building two hotels that will be the same height, and have bases that are the same size. One will be a rectangular prism and the other will be a rectangular pyramid. Which building will require more gallons of paint to completely cover it? Why?
Answers
Answer:
The rectangular prism building.
Step-by-step explanation:
The rectangular prism building will require more gallons of paint to completely cover because, compared to the rectangular pyramid, the rectangular prism has a larger surface area, thus it would need more paint to completely cover it.

An electrician charges Mr. Speer $300 before sales tax, for wiring his home. (a) What is the amount of sales tax that Mr. Speer has to pay? (b) What is the total amount Mr. Speer has to pay?
Answers
Answer: See explanation
Step-by-step explanation:
Your question isn't complete as you didn't give the sales tax percent. In order to solve the question, let's assume that the sales tax is 6%.
(a) What is the amount of sales tax that Mr. Speer has to pay?
This will be:
= Sales tax percent × Amount charged
= 6% × $300
= 6/100 × $300
= 0.06 × $300
= $18
The sale tax is $18
(b) What is the total amount Mr. Speer has to pay?.
The total amount will be the addition of the amount charged and the sales tax. This will be:
= $300 + $18
= $318

El numero es 12
Pregunta 2.
27 - 5= 22 dividido 2 = 11
El numero que pensastes es 11
Pregunta 3.

Use el metedo reversa.
Construyendo y resolviendo las ecuaciones, encontramos que:
1. El numero es 12.2. El numero es 11.3. La edad de Juan es 12.---------------
Ejercicio 1
El número es x.Sumando 15, tenemos x + 15 Obtuve 27, entonces:[tex]x + 15 = 27[/tex]
[tex]x = 27 - 15 = 12[/tex]
El numero es 12.---------------
Ejercicio 2
El número es x.Multiplicando por 2, tenemos 2x. Sumando 5, tenemos 2x + 5.Obtuve 27, entonces:[tex]2x + 5 = 27[/tex]
[tex]2x = 22[/tex]
[tex]x = \frac{22}{2}[/tex]
[tex]x = 11[/tex]
El numero es 11.---------------
