Answer 2

Answer:

11) Perimeter = 61.6inches or 61.64inches

12) Perimeter = 71.2inches or 71.24inches.

Step-by-step explanation:

Shape 11; = square 11 x 14 = 140+14 = 154 area

Perimeter square side  is just three sides

= 11 x 2 + 14 = 36 inches

Shape 11 triangle = b9^2 + 14^2 = sqrt 81+ sqrt 196 = sq rt 277 = 16.643317

So we use 9+ 16.643317 =25.643317

Perimeter = 25.6 + 36 = 61.6 inches

Shape 12; =

We have 20 and 16 so we square these and take away to find a^2

20^2 - 16^2 = sq rt 144 = 12 inches vertical top line

Then repeat for missing slant edge but add instead of subtract as its a slant line we are looking for

12^2 + 10^2 = 144 +100 = 244 sq rt = 2√ 61.  = 15.62 inches

Perimeter therefore is 20+20 as they both sets are congruent shapes = 40

+ 15.62+15.62 = 31.24

31.24+40= 71.24 inches

3053.63=πr^2h

what is h?

Answers

Answer:

h = 12

Step-by-step explanation:

3053.63=πr^2h

Let r=9 and approximate pi as 3.14

3053.63=3.14 ( 9)^2 h

3053.63=3.14*81*h

3053.63=254.34h

Divide each side by254.34

3053.63/254.34=254.34h/254.34

12=h

Answer:

[tex] h = \dfrac{3053.63}{\pi r^2} [/tex]

Step-by-step explanation:

3053.63 = πr²h

Switch sides.

πr²h = 3053.63

Divide both sides by πr².

h = 3053.63 / πr²

Answers

Answer:

72.25

Step-by-step explanation:

Triangles are 1/2(base x height), or (base x height) / 2.

17 x 8.5 = 144.5

144.5 / 2 = 72.25

74.25 square inches.

The formula to find the area of a triangle is A = 1/2(b)(h). (b being base and h being height)

A=1/2(17)(8.5)
A=1/2(144.5)
A= 72.25 :)

C) 1,440
D) 900

Answers

Answer:

Option B; 1620

Step-by-step explanation:

The formula of finding the sum of interior angles = (n-2) * 180 where n is the number of sides the polygon has.

=> (11-2) * 180

=> (9) * 180

=> 1620

Hope this helps!

The answer is b) 1,620

Answers

Answer:

x = -7

y = 42

Step-by-step explanation:

y = -6x

y = -8x - 14

substitute -6x in the second equation for y

-6x = -8x - 14

add 8x to both sides

2x = -14

divide both sides by 2

x = -7

----------------

substitute that in to the first equation to solve for y:

y = -6(-7)

y = 42

----------------------------------

check the math:

y = -8x - 14

42 = -8(-7) - 14

42 = 56 - 14

42 = 42

yeah sorry i can’t help you :(

If the graph is linear then constant of proportionality is represented by slope of line.

Since, graph shows a proportional relationship.

It means that y is directly proportional to x .

So, we get                 [tex]y=mx[/tex]

Where m is proportionality constant.

Since, graph is linear , Therefore, proportionality constant represent slope of line.
