What is the surface area of the composite figure
leva [86]

Answer:

The answer is 672.

Step-by-step explanation:

To solve this problem, first let's find the surface area of the rectangular prism. To do that, multiply each dimension with each (times 2 | just in case you don't understand [what I'm talking about is down below]).

8 x 8 x 2 = 128

8 x 11 x 2 = 176

8 x 11 x 2 = 176

Then, add of the products together to find the surface area of the rectangular prism.

176 + 176 + 128 = 480

Now, let's find the surface area of the square pyramid. Now, for this particular pyramid, let's deal with the triangles first, then the square. Like we did with the rectangular prism above, multiply each dimension with each other (but dividing the product by 2 | in case you don't understand [what i'm talking about is down below]).

8 x 8 = 64.

64 ÷ 2 = 32.

SInce there are 4 triangles, multiply the quotient by 4 to find the surface area of the total number of triangles (what i'm talking about is down below).

32 x 4 = 128.

Now, let's tackle the square. All you have to do is find the area of the square.

8 x 8 = 64.

To find the surface area of the total square pyramid, add both surface areas.

128 + 64 = 192.

Finally, add both surface areas of the two 3-D shapes to find the surface area of the composite figure.

192 + 480 = 672.

Therefore, 672 is the answer.

Find the distance between the points (-3, 11) and (5,5).<br> O 10<br> 2/10<br> o 2.17
german

Answer: d = 10

Step-by-step explanation:

Step-by-step explanation:

The formula for calculating distance between two points is given by :

d = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}

x_{1} = -3

x_{2} = 5

y_{1} = 11

y_{2} = 5

substituting the values , we have

d = \sqrt{(5-(-3))^{2}+(5-11)^{2}}

d = \sqrt{(5+3)^{2}+(-6)^{2}}

d = \sqrt{(8)^{2}+(-6)^{2}}

d = \sqrt{64+36}

d = \sqrt{100}

d = 10

A bag held 4 black marbles, 2 red marbles, and 6 white marbles. I drew a black marble and did not replace it. What is the probab
Helga [31]

Answer:

P (black marble) =3/11

Step-by-step explanation:

We need to find the total number of marbles

4 black marbles+ 2 red marbles+ 6 white marbles= 12 marbles

We take away a black marble and throw it away

3 black marbles+ 2 red marbles+ 6 white marbles= 11 marbles

The probability of drawing a black marble is

P (black marble) = black/total

                           =3/11
