Find area of the composite figure..

Find Area Of The Composite Figure..

Answers

Answer 1

Answer:

627square inches

Step-by-step explanation:

Area of the composite figure.. = area of triangle + area of parallelogram

Since the triangle is an equilateral triangle;

Area of the triangle = r²sintheta

Area of the triangle = 18²sin60

Area of the triangle = 324sin60

Area of the triangle  = 324(0.8860)

Area of the triangle = 280.584 square in

Area of the triangle = 281 square inches

Area of parallelogram = absintheta

Area of parallelogram = 20(20)sin60

Area of parallelogram = 400(0.8660)

Area of parallelogram = 346.4square inches

Area of parallelogram = 346 square inches

Area of the figure = 346  + 281

Area of the figure  = 627square inches

Find the theoretical probability that the spinner below lands on the letter B. Write your answer as a fraction in simplest form. Use "/" for fractions with no s

Answers

Answer:

The theoretical probability that the spinner below lands on the letter B is 1/2

Step-by-step explanation:

Given

[tex]S =\{A,B,B,B,C,C\}[/tex]

[tex]n(S) = 6[/tex]

See attachment for spinner

Required

P(B)

From the attached spinner, we have:

[tex]n(B) = 3[/tex] --- occurrence of B

So:

[tex]P(B) = \frac{n(B)}{n(S)}[/tex]

[tex]P(B) = \frac{3}{6}[/tex]

[tex]P(B) = 1/2[/tex]

The current in a certain resistor is 0.50A when it is connected to a potential difference of 110V. If the operating potential is 130V, the current in the same resistor is

Answers

Answer:

0.59 A

Step-by-step explanation:

The current in a certain resistor is 0.50 A

The potential difference is 110v

The operating potential is 130v

The current in the same resistor can be calculated as follows

= 110/0.50

= 220

= 130/220

= 0.59

Hence the current is 0.59 A

first you need to subtract the total number of students 340, by 4:00 because four of them had to travel in cars so they weren't on the bus. since there are seven buses and now 336 students going to travel on buses each buses must be split equally so you need to divide 336 by 7 giving you 48

The price of a house is originally listed at $150,000. The owners are having a hard time selling it and decide to reduce the price to $115,500. What is the percentage decrease of the price of the house?

Answers

Answer:

there is a 23% decrease in the price of the house

Step-by-step explanation:

percentage decrease of the price of the house = (price decrease of the house / initial price of the house) x 100

price decrease of the house =new price - initial price

$115,500 -  $150,000 = $-34,500

( $-34,500 / $150,000) x 100 = -23%

What is the surface area of the cylinder with a height of 3 m and radius of 4 m? Round your answer to the nearest thousandth.

Answers

Answer:

The surface area of the cylinder is of 131.947 square meters.

Step-by-step explanation:

Surface area of a cylinder:

The surface area of a cylinder of height h and radius r is given by the following equation:

[tex]S_a = 2\pi r(h+r)[/tex]

What is the surface area of the cylinder with a height of 3 m and radius of 4 m?

[tex]h = 3, r = 4[/tex].

So

[tex]S_a = 2\pi r(h+r) = 2\pi(3)(3+4) = 42\pi = 131.947[/tex]

Height and radius are in meters, so the surface area will be in square meters.

The surface area of the cylinder is of 131.947 square meters.
