Area of trapezoid: a+b/ 2 * H

a = top, b= bottom, H = height

6+14/2 * 8

20/2 *8

10*8

80

Answer:

20

Step-by-step explanation:

To find area using coordinates, you would take the y-value of the first coordinate and the x-value of the second coordinate and multiply them. Then, take the x-value of the first coordinate and multiply it with the second y-coordinate. Take the second number and subtract it from the first number. for multiple coordinates, you would multiply the first and the second, the second and the third, and so on. Once you reach the last coordinate, just multiply it by the first again. then, take all of the numbers, from multiplying your coordinates and add them together and divide them by 2 to find your area.

We would start with coordinate (8,1) here because it's letter variable is W, which is first of the others alphabetically.

(8,1) (1,1)

1 x 1 = 1

8 x 1 = 8

1 - 8 = -7

next coordinate:

(1,1) (2,5)

1 x 2 = 2

1 x 5 = 5

2 - 5 = -3

next:

(2,5) (5,5)

5 x 5 = 25

2 x 5 = 10

25 - 10 = 15

next:

(5,5) (8,1)

5 x 5 = 40

5 x 1 = 5

40 - 5 = 35

-7 - 3 + 15 + 35 = 40

40/2 = 20

Answer:

Equation of a circle:

radius = the sq. rt of (x - h)^2 + (y - k)^2

Plug in the values for the center of a circle and the radius:

15 = the sq. rt of (x + 9)^2 + (y + 4)^2

(x + 9)^2 + (y + 4)^2 = 225

The answer is A or the first one.

Answer:

D x>-3

Step-by-step explanation:

3(-x+2) < 15

-3x + 6< 15 (Subtract 6 from both sides)

-3x < 9 (Divide 3 on both sides)

x>-3 (Flip the inequality because the variable was negative)

Answer:

She should have added 3, not subtracted 3, to both sides

Step-by-step explanation:

this problem calls for the inverse of operations

[tex]x-3=7\\\\\\3+x-3=7+3\\\\x=10[/tex]

Answer:

She should have added 3, not subtracted, to both sides

Step-by-step explanation:

You're trying to get X by itself and to do that you need to add 3 to cancel out the -3.

Answer:

a. 1. Trapezoid

2. Rectangle

b. Trapezoid

c.  Isosceles trapezoid

d. 6 feet

e. 65°

f. 115°

Step-by-step explanation:

a. The observed quadrilaterals are;

1. Trapezoid

2. Rectangle

b. Trapezoid

c.  Isosceles trapezoid

d. Whereby we have an isosceles trapezoid, the leg lengths are equal. therefore since one of the leg lengths = 6 feet, the other opposite leg on the side of the roof = 6 feet

e. The base angles of an isosceles triangle are equal, therefore, the other base angle is equal to the labelled base angle or 65°

f. The sum of the opposite angles in an isosceles trapezoid = 180°

∴ 65° + Opposite angle = 180°

Opposite angle = 180° -  65° = 115°.

Answer:

Step-by-step explanation:

y - 5 = 3(x+ 2)

y - 5 = 3x + 6

y = 3x + 11

If the mean is 4 then the missing number will be 2.

The mean is the average of all the data values present in the data set.

Mean=sum/number

Let the missing number be x in this way mean will be

(1+9+x)/3=4

10+x=12

x=2

Hence if mean is 4 then the missing number will be 2.

Step-by-step explanation: This is a simple subtraction problem. You take the amount of the DVD player ( which is $62.50 ) and subtract the amount of money Jack has on him ( which is $50 ).

$62.50 - $50.00 = $12.50

Answer:

p = -2

Step-by-step explanation:

(2p -1)/5 = (p-1)/3

Using cross products

(2p-1) *3 = (p-1)*5

Distribute

6p-3 = 5p -5

Subtract 5p from each side

6p-5p -3 = 5p-5p -5

p -3 = -5

Add 3 to each side

p-3+3 = -5+3

p =-2

Answer:

x = 13

Angle 1 = 150 degrees

Angle 8 = 30 degrees

Step-by-step explanation:

11x + 7 + x + 17 = 180

12x + 24 = 180

12x = 180 - 24

12x = 156

x = 13

11(13) + 7 = 150

(13) + 17 = 30

The co-interior angles are solved and x = 13

The measure of angle 1 = 150°

The measure of angle 1 = 30°

Given data:

Angles in parallel lines are angles that are created when two parallel lines are intersected by another line.

Alternate angles are equal

Corresponding angles are equal

Co-interior angles add up to 180°

The angles 1 and 8 are co-interior angles.

So, 11x + 7 + x + 17 = 180

12x + 24 = 180

12x = 180 - 24

12x = 156

x = 13

So, the measure of angle 1 = 11(13) + 7 = 150°

The measure of angle 8 = (13) + 17 = 30°

Hence , the parallel lines are solved.

It would be the first one

Step-by-step explanation:

Answer:

So we can first use the distance formula which is for 2 dimensional but seen as we're in 1 dimensions we dont have to use it. So we can just get the distance between them using a formula I made -

|a-d| = distance

So if we use that formula we can get that -7-(-2) = -7+2 = -5. Then take the absolute value which is 5.
