Answer:

When y=276, x= 23

Step-by-step explanation:

Since they're directly proportional, when divided they have to equal the same.

180/15= 12 and 276/23= 12

A solid piece of wood shaped as a cylinder with an 8-centimeter diameter is cut as shown.
zhuklara [117]

Answer:

The surface area of the figure is 96 + 64π ⇒ 1st answer

Step-by-step explanation:

* Lats revise how to find the surface area of the cylinder

- The surface area = lateral area + 2 × area of one base

- The lateral area = perimeter of the base × its height

* Lets solve the problem

- The figure is have cylinder

- Its diameter = 8 cm

∴ Its radius = 8 ÷ 2 = 4 cm

- Its height = 12 cm

∵ The perimeter of the semi-circle = πr

∴ The perimeter of the base = 4π cm

∵ The area of semi-circle = 1/2 πr²

∴ The area of the base = 1/2 × π × 4² = 8π cm²

* Now lets find the surface area of the half-cylinder

- SA = lateral area + 2 × area of one base + the rectangular face

∵ LA = perimeter of base × its height

∴ LA = 4π × 12 = 48π cm²

∵ The dimensions of the rectangular face are the diameter and the

   height of the cylinder

∴ The area of the rectangular face = 8 × 12 = 96 cm²

∵ The area of the two bases = 2 × 8π = 16π cm²

∴ SA = 48π + 16π + 96 = 64π + 96 cm²

* The surface area of the figure is 96 + 64π

Suppose your mom or dad asks you to make a triangular garden in the backyard. You know that one side of your yard (AC) is 100 ya
SVEN [57.7K]

Answer:

  • 23.5°

Step-by-step explanation:

<u>Use the law of sines:</u>

  • AC / sin B = AB / sin C
  • 100 / sin B = 250 / sin 95°
  • sin ∠B = 100 sin 95° / 250
  • sin ∠B = 0.39847787923
  • m∠B = arcsin 0.39847787923
  • m∠B = 23.5° (rounded up)

I need help for real, no helpless answers please!
nikklg [1K]

Given:

m∠R = 90°

m∠Q = 6°

PQ = 2.2 ft

RP = x

To find:

The length of RP.

Solution:

Using basic trigonometric formula:

$\sin \theta =\frac{\text{Opposite of} \ \theta}{\text{Hypotenuse}}

$\sin 6^\circ =\frac{x}{2.2}

$0.1=\frac{x}{2.2}

Multiply by 2.2 on both sides.

$0.1\times2.2=\frac{x}{2.2}\times2.2

$0.22=x

$0.2=x (nearest tenth)

The length of RP is 0.2 feet.
