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.

If Jake's height from birth (measured in inches) can be modeled by the Linear Regression Equations y = 4.3x +19, with x representing his age in years after birth What does this slope mean in the context of the problem

Answers

His height. To explain, if he was a newborn his age, x, would be 0. That can be modeled by y=4.3(0)+19 and so y would equal 19. He was 19 inches as a newborn. When he turned 1, x changed to 1. This can be shown by y=4.3(1)+19 where his height, y, is now 23.3 inches. The 19 stays constant because he was 19 inches as a newborn and every year that he grows older he grows 4.3 inches.

The sum of the interior angle measures of a convex octagon is 1080. the correct option is A.

What is an octagon?

An octagon is an 8-gon, or polygon with eight sides, in geometry. The Schläfli symbol for a regular octagon is 8, and it can also be built as a nearly regular truncated square.

The interior angle will be calculated as,

Angle = (n - 2) x 180

Angle = ( 8 - 2 ) x 180

Angle = 1080

Therefore, the sum of the interior angle measures of a convex octagon is 1080. the correct option is A.

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.

Answer:

  100% is an integer multiple of 10%

Step-by-step explanation:

100% is not an integer multiple of 30%, so it is difficult to use 30% directly to determine the value of 100%. Dividing 30% by 3 to get 10% then gives you a value that can be multiplied by 10 to find 100%.

Anyone know this?? Question: find the area of the shape. Don’t forget your units and use 3.14 if you need to use pi.

Answers

Quick answer :

Area of this shape = 614²

Answer with steps :

Length of side of the first square = 10

It's area :

[tex] =\tt side \times side[/tex]

[tex] = \tt10 \times 10[/tex]

[tex] = \tt {100}^{2} [/tex]

Thus, the area of the first square = 100²

Length of the side of the second square = 10

It's area :

[tex] = \tt \: side\times side[/tex]

[tex] =\tt 10 \times 10[/tex]

[tex] = \tt{100}^{2} [/tex]

Thus, the area of the second square = 100²

Length of the side of the third square = 10

It's area :

[tex] =\tt side \times side[/tex]

[tex] = \tt 10 \times 10[/tex]

[tex] = \tt {100}^{2} [/tex]

Thus, the area of the third square = 100²

(pi value = 3.14)

Radius of the first semicircle = 10 cm

It's area :

[tex] = \tt \: \frac{\pi {r}^{2} }{2} [/tex]

[tex] = \tt \frac{3.14 \times 10 \times 10}{2} [/tex]

[tex] = \tt\frac{3.14 \times 100}{2} [/tex]

[tex] =\tt \frac{314}{2} [/tex]

[tex] =\tt {157}^{2} [/tex]

Thus, the area of the first semicircle = 157²

Area of the second semi circle :

= area of the first semicircle

= 157²

Thus, the area of the second semicircle = 157²

Total area of the figure :

= Area of the 3 squares + Area of the two semi circles

[tex] =\tt 100 + 100 + 100 + 157 + 157[/tex]

[tex] = \tt300 + 314[/tex]

[tex] = \tt {614}^{2} [/tex]

Therefore, the total area of the figure = 614²
