Answer:

138 cm^2 = Area .          54 cm = Perimeter

Step-by-step explanation:

Find the area of the triangle-                                   <u>b * h</u> = A

                                                                                     2

                                                                                   <u>8 * 6</u> = A

                                                                                      2

                                                                                   48/2 = A

                                                                                     24 = A

Find the area of rectangle-                                        l * w = A

                                                                                   16 * 7 = A

                                                                                      112 = A

Add the areas together.                                            24 + 112 = 136 cm^2

Perimeter is adding up all the sides.                         s + s + s + s + s

                                                                                   16 + 7 + 8 + 10 + 13 = 54 cm

Answer:

<em>perimeter</em><em> </em><em>of </em><em>this </em><em>figure</em><em> </em><em>is </em><em>=</em><em> </em><em>5</em><em>4</em><em> </em><em>cm</em>

<em>and </em><em>area </em><em>of </em><em>traingle</em><em> </em><em>is </em><em>=</em><em> </em><em>1</em><em>/</em><em>2</em><em>*</em><em>base </em><em>*</em><em>height</em>

<em>so </em><em>=</em><em> </em><em>1</em><em>/</em><em>2</em><em>*</em><em>8</em><em>*</em><em>6</em>

<em>=</em><em>. </em><em>2</em><em>4</em><em>c</em><em>m</em><em>*</em><em>cm</em>

<em>and </em><em>area </em><em>of </em><em>rectangle</em><em> </em><em>=</em><em> </em><em>length</em><em> </em><em>*</em><em> </em><em>breadth</em><em> </em>

<em> </em><em>area </em><em>=</em><em> </em><em>1</em><em>1</em><em>2</em><em>c</em><em>m</em><em>*</em><em>cm</em>

<em>so </em><em>total </em><em>area </em><em> </em><em>=</em><em> </em><em>1</em><em>1</em><em>2</em><em>+</em><em> </em><em>2</em><em>4</em><em> </em><em>=</em><em> </em><em>1</em><em>3</em><em>6</em><em>c</em><em>m</em><em>*</em><em>cm </em>

hope it helps and your day will full of happiness

A bag contains 3 red, 6 blue, 5 purple, and 2 orange marbles. One marble is selected at random. What is the probability that the
mamaluj [8]

Answer:

P(blue)=37.5\%

Step-by-step explanation:

-Probability is the likelihood of an event occurring.

-The total number of events is:

Total=3+6+5+2\\\\=16

-The total number of blue events is:

Blue=6

#Probability of a blue is thus calculated as:

P(Blue)=\frac{Blue}{Total}\\\\=\frac{6}{16}\\\\=0.375\\\\=37.5\%

Hence, the probability of choosing a blue marble at random is 37.5%

Which relationships have the same constant of proportionality between yyy and xxx as the equation 3y=27x3y=27x3, y, equals, 27,
Tanya [424]

Answer:

A, B and C

Step-by-step explanation:

In the equation: 3y=27x

Making y the subject of the equation, we have:

y=\frac{27}{3}x\\y=9x

The constant of proportionality between y and x  is 9.

We want to determine which relationships have the same constant of proportionality 9.

<u>Option A</u>

y=9x

The constant of proportionality is 9.

<u>Option B</u>

2y=18x

Divide both sides by 2 to obtain: y=9x

The constant of proportionality is 9.

<u>Option C</u>

x=3, y=1/3

Substitution into y=kx gives:

1/3=3k

k=9

The constant of proportionality is 9.

<u>Option D</u>

x=6, y=2/3

Substitution into y=kx gives:

2/3=6k

k=2/3*6=4

The constant of proportionality is 4.

<u>Option E</u>

When x=2, y=18

Substitution into y=kx gives:

18=2k

k=9

However, when x=4, y=27

Substitution into y=kx gives:

27=4k

k=6.75

This is not a proportional relation since the constant of proportionality is not equal.

The correct options are A, B and C
