Answer 1

Answer:

6

Step-by-step explanation:

First, find the total number for the set of four numbers. To do this, multiply 3.5 and 4. We do this because the mean is division, so we need to get back to the original amount.

3.5 x 4 = 14

Next, we need to find the other total when the mean is 4. There are 5 numbers, which tells us we had to divide the total by 5 to get 4. So, again, we want to multiply the mean, 4, and the 5 to get the total.

5 x 4 = 20

Finally, find the number we added in. To do this, we subtract the two totals.

20 - 14 = 6

Step-by-step explanation:

(20 POINTS) One side of a trapezoid is extended and the dotted line forms a right angle with the extended line.

Answers

Answer: p = 115* (degrees)

Explanation:

What we know:

The trapezoid forms a right triangleThe right triangle has the angles 25*, 90*, and an unknownThe internal angles of a triangle add up to 180*The unknown value p is a supplementary angle to the right triangle's unknown angle

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.

Process:

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

Answer: p = 115*

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.

the area of the east facing homes is 8 times 10= 80 blocks

and the area of the trapezoid is 5 plus 3 times 3 = 15 blocks

so 100+80+15= 195 square blocks
