Some blocks are stacked as shown. If the face of each block is a square and each block represents one cubic unit, what is the surface area of the figure formed by the blocks?
A. 30 square units
B. 28 square units
C. 24 square units
D. 21 square units

Answer:

31/6

Step-by-step explanation:

36/4=9

6x-22= 9

6x= 9+22

substitute 6x=31= 31/6

Answer:

x = 31/6

Step-by-step explanation:

first lets isolate the equation which equals, 6x-24+2 = 9

I got 9 from 36/4, divide top and bottom by 4 = 9

Next add the numbers, 6x -24+24= 9 turns into 6x-22= 9

Now move the -22 to the side the 9 is, 6x= 9+22

and now we can solve and substitute, 6x=31, which gives us 31/6

Answer: p = 115* (degrees)

What we know:

How to solve:

    By finding the degree of the 3rd angle in the right triangle, we can use the rules of supplementary angles to find the value of p.

    We will use D to represent the total amount of degrees, which will equal 180*. X will represent an unknown angle. An asterisk represents the degree symbol.

Missing right triangle angle

Set up equation                                                     D = 25 + 90 + x

Substitute                                                            180 = 25 + 90 + x

Simplify                                                                180 = 115 + x

Isolate variable                                                   -115    -115

Solution                                                               65* = x

Value of p using supplementary angles

Set up equation                                                     D = x + p

Substitute                                                           180 = 65 + p

Isolate variable                                                 -65     -65

Solution                                                              115* = p

Check:

We can do a check based on estimation. Assuming that the trapezoid and triangle form a box with all 90* corners and that p = 115*, then adding p and all of the other trapezoid angles should result in 360*

Firstly, we need the values of these 4 angles.

The first angle, labeled p, should be 115*. If our equation is untrue, then this value will fail the check.

The second angle will be the one at the bottom-left, which is 90* according to our box statement.

The third angle is the one located at the bottom-right, which is also 90* from the box statement.

The fourth angle is not 90* or 115*, but we can solve its value.

Because we have stated that the right triangle and trapezoid form a box with 4 90* corners, the sum of the fourth angle and the 25* from the right triangle must form a right angle. Let's find the value:

D = 25 + x

90 = 25 + x

(90 = 25 + x) - 25

65* = x

Therefore, the fourth angle has 65*

Now, adding the degrees from all 4 angles should result in a total of 360*. If it does, then our value of p = 115* will pass the check.

D = 90 + 90 + p + x

360 = 90 +90 + 115 + 65

360 = 180 + 180

360 = 360

Therefore, p = 115*

Answer:

C

Step-by-step explanation:

A and B are out because we can already tell that 65 and 75 are smaller than the 90 degrees whichs this angle is even higher than.If you see or use a protrater you can see it seems more likely to 115 because 155 would be much more open.

Answer:

∠M will be 147°

Step-by-step explanation:

Supplementary means adding up to 180° so take your 180° to subtract 33° from it and you'll have your answer.

Answer:

147

Explanation:

Supplementary angles all equal to 180, so that means that <M and <N must be both equal to 180.

If you want to find <M, you have to do 180 - 33, which equals to 147.

Answer:    Find the area of the trapezoid!

Step-by-step explanation:

Surface Area = 2×(12×13 + 12×14 + 13×14)

Hopefully this helps you!

-Keira

Answer:

169 mi²

Step-by-step explanation:

To find the area of a trapezoid, use this formula:

[tex]A=\frac{a+b}{2} h[/tex]

"a" and "b" represent the two bases (12 mi and 14 mi), and the "h" stands for height (13 mi). Insert these values into the equation.

[tex]A=\frac{12+14}{2} 13[/tex]

[tex]A=\frac{26}{2} 13[/tex]

[tex]A=13 * 13\\= 169[/tex]

Therefore, A = 169. :)

Answer:

  (b)  2 32/48

Step-by-step explanation:

You want the value of the expression 8 4/8 -5 5/6.

The difference of the mixed numbers can be found as the sum of the differences of the integer parts and fractional parts.

  (8 4/8) -(5 5/6) = (8 -5) +(4/8 -5/6)

  = 3 + ((24 -40)/48) = 3 - 16/48

  = 2 +(48/48 -16/48) . . . . . . . rewrite 3 to give a positive fraction part

  = 2 32/48 . . . . matches the 2nd choice

Answer:

Step-by-step explanation:

1. A ticket at the NBA championship game costs $200 each. You will be given a discount of 8% if you buy early.

Your parents gave your $570

a) How much will you pay if you buy early.

$200 * 0.08 = $16 (how much you get off)

$200 - $16 = $184

This means that you will pay $184 for each ticket if you buy early.

b) Opps the tax is 4.5%.

4.5/100 = 0.045

$184 * 0.045 = $8.28 (how much you will be paying for tax)

c) How much will you pay including tax?

$184 + $8.28 = $192.28

d) How much will you pay for your two brothers?

You + your two brothers = 3 people

$192.28 * 2 = $384.56

Total for all 3 people: $192.28 + $384.56 = $576.84

e) Do you still have money for popcorn if your parents will give you $570.00?

The total cost of the tickets for you and your brothers is $576.84.

$576.84 is greater than $570.

So, no. You won't have money for popcorn.

Hope this helps!

Answer:

[tex]\frac{8}{9}[/tex]

Step-by-step explanation:

So, there are 8 pieces with color and 1 piece without the wanted color.

The equation for finding the probability is:  [tex]\frac{sum of terms }{number of terms }[/tex]

Therefore: 3 + 5 = 8  and 9 pieces in total

so the correct answer should be 8/9

solution = 4 ?

6 * 4 - 3 = 24 - 3 = 21 not 45 so 4 is not the solution

the solution = 8

6 * 8 - 3 = 48 - 8 = 45

Answer:

8

Step-by-step explanation:

Let us first sole the equation for x.

6x - 3 = 45

-> 6x = 45 + 3

-> 6x = 48

-> x = 48/6

-> x = 8

Thus 8 from the set {4, 5, 6, 7, 8} makes the equation 6x - 3 = 45 true.

Answer:

The answer is 23 because they have to add up to 90-kai :)

Step-by-step explanation:

So, ∠a + ∠b = 90°

67° + ∠b = 90°

∠b = 90° - 67°

∠b = 23°

Answer:

The measure of ∠b is 23°.

Step-by-step explanation:

Complementary angles are angles that add together to always be 90°. The problem gives us this information at the start:

∠a + ∠b = 90°

∠a = 67°

You can apply this information to the equation by getting the problem of:

67° + ∠b = 90°

To solve this equation you simply rearrange the terms, and subtract 67 from 90:

90° - 67° = ∠b

After rearranging the terms and subtracting 67 from 90 you are left with the following result:

∠b = 23°

Answer:

7%

Step-by-step explanation:

First, let's add the 20 dogs and 15 cats together to find the total number of animals adopted

20 + 15 = 35 animals adopted

We cand do 35 ÷ 200 to find how much of a percent 35 is of 500

35 / 500 = 0.07

Multiply this number by 100 to get a percent

0.07 × 100% = 7%

7% of the animals
