Area - Triangles
Overview

Answers

Answer:

There are 3 possible answers because you didn't state which value was base or height.

Going off the assumption that the base is 15 cm and the height is 8 cm, the area is 60 cm. (same answer if base is 8 cm and height is 15 cm)

A = 1/2(b*h)

A = 1/2(15*8)

A = 1/2(120)

A = 60

Going off the assumption that the base is 17 cm and the height is 8 cm, the area is 68 cm. (same answer if base is 8 cm and height is 17 cm)

A = 1/2(b*h)

A = 1/2(17*8)

A = 1/2(136)

A = 68

Going off the assumption that the base is 15 cm and the height is 17 cm, the area is 127.5 cm. (same answer if base is 17 cm and the height is 15 cm)

A = 1/2(b*h)

A = 1/2(15*17)

A = 1/2(255)

A = 127.5

m∠RST=m∠RSV+m∠VST
m∠RSV=m∠VST

m∠RST=2*m∠RSV --------> equation 1
we have
m∠RST=(6x-24)
m∠RSV=(2x+8)
Substitute in the equation 1
6x-24=2*(2x+8)
6x-24=4x+16

Colton has 888 comedy movies, 666 action movies, 555 fantasy movies, and 111 drama movie on his list of favorite movies. For every 555 movies on the list, there are 222 \_\_\_\_____\_, \_, \_, \_ movies.

Answers

Answer: Comedy

Step-by-step explanation:

Find out the percentages of each of the movies. First find the total quantity.

= 888 + 666 + 555 + 111

= 2,220 movies

Comedy = 888/2,220 * 100% = 40%

Action = 666 / 2,220 * 100% = 30%

Fantasy = 555/2,220 * 100% = 25%

Drama = 111/ 2,220 * 100% = 5%

222 movies out of 555 is:

= 222 / 555 * 100%

= 40%

222 movies out of 555 movies will therefore be comedy.

Answer:

222/555 are comedy

Answers

Answer:

  (c)  3√3

Step-by-step explanation:

The altitude forms the long side of a 30°-60°-90° right triangle whose short side is 6/2 = 3 cm.

The ratios of side lengths in a 30°-60°-90° triangle are ...

  1 : √3 : 2

Multiplying these ratio values by 3 gives the right triangle side lengths of ...

  3 : 3√3 : 6

where 6 is the side length of the equilateral triangle. The length 3√3 is the altitude of that equilateral triangle.

The height of the triangle is 3√3 cm.

over the past ten years, the towns population doubled in size. the population is currently 12,000. what was the population ten years ago?

which of the following represents the given word problem if “P” represents the population ten years ago?
1. P=2(12,000)
2. 2P=12,000
3. 2(P+10)=12,000

Answers

Answer:

If P represents the population ten years ago, the current population can be expressed as: 2P = 12,000 (or: 2 x 6,000 = 12,000). Over the past ten years, the town's population doubled in size. The population is currently 12,000. Therefore the population ten years ago was 12,000 divided by 2 = 6000.
