Use the Pythagorean theorem to find z.

Answer:

1/5

Step-by-step explanation: First, turn 1/2 so that the denominator is the same as the other fraction (multiply both by 5 to get 5/10). Now subtract to get 2/10. Then, divide both by 2 to get the fraction in the simplest form.

Answer:

The answer is below

Step-by-step explanation:

The distance between the upper left coordinate and the upper right coordinate is the length of the rectangle. Hence:

[tex]length=\sqrt{(4-(-1))^2+(7-7)^2} =5\ units\\[/tex]

Area = length * breadth

20 = 5 * breadth

breadth = 4 units

The bottom left coordinate would have the same x coordinate as the upper left coordinate. Hence, bottom left coordinate = (-1, y₁)

The distance between the upper left coordinate and the bottom left coordinate is the breadth of the rectangle. Hence:

[tex]breadth=\sqrt{(-1-(-1))^2+(y_1-7)^2} =4\ units\\\\ y_1-7=\pm 4\\\\y_1=4+7=11\ \ or\ y_1=-4+7=3[/tex]

Since it is at the bottom, hence y₁ = 3. Hence bottom left coordinate = (-1, 3)

Bottom right coordinate has same y coordinate as bottom left coordinate and same x coordinate as upper right. Hence bottom right coordinate = (4, 3)

Answer:

360m²

Step-by-step explanation:

Surface area of Pyramid=4*Area of Triangle+Area of Square

Area of Triangle=(1/2)*Base*Height

Area of Square=Side²

Area of 4 Triangles=4*(1/2)*10*13=260m²

Area of square=10²=10*10=100m²

Total Area=260m²+100m²=360m²

Answer:

a.

2x+4x+3x=180 sum of interior angle of the triangle is 180

9x=180

x=180/9=20

b.

x-20+x+10+x-20=180sum of interior angle of the triangle is 180

3x-30=180

3x=180+30

x=210/3=70

c.x+10+x+20+x=180 linear pair

3x+30=180

3x=180-30

x=150/3=50

Answer:

The picture is kinda blurry so I hope I've got it right.

a) x = 20°

b) x = 70°

c) x = 50°

Step-by-step explanation:

a) 2x + 3x + 4x = 180°

9x = 180°

x = 50°

b) (x - 20°) + (x - 20°) + (x + 10°) = 180°

3x - 30° = 180°

3x = 210°

x = 70°

c) (x + 10°) + (x + 20°) + x = 180°

3x + 30° = 180°

3x = 150°

x = 50°

Answer: 15 / 56

Step-by-step explanation:

Number of red checkers = 3

Number of black checkers = 5

Total number of checkers = 8

P(black, then red) = 5/8 × 3/7 = 15/56

We should note that the probability to pick a black checker first will be 5 out of 8. Then, there'll be 7 checkers left and the probability to pick a res checker will be 3/7. We then multiply the probabality of each together.

Answer:

x = 12 and y = 9

Step-by-step explanation:

Using the similarity theorem to fid the value of x and y

16/x = 16+6/16.5

16/x = 22/16.5

22x = 16*16.5

22x = 264

x = 264/22

x =12

Similarly

24/x = 24+y/16.5

24/12 = 24+y/16.5

2 = 24+y/16.5

24+y = 2 * 16.5

24+y = 33

y = 33-24

y = 9

Hence x = 12 and y = 9

Answer:

124 inches square

Step-by-step explanation:

First area of that rectangle 20×5 = l×b = 100

Second area of that triangle 6×8×1/2 = 24

Third add both rectangle+triangle=100+24=124

The unit rate of demonstrated in the graph will be 4.5 miles per hour. Then the correct option is B.

The rate is the proportion of how much something is to the unit. For instance - Assuming that the speed of the vehicle is 20 km/h it implies the vehicle voyages 20 km in 60 minutes.

The incline is the proportion of rising or falling and running. The contrast between the ordinate is called rise or fall and the distinction between the abscissa is called run.

The slope of the line is given as,

m = (y₂ - y₁) / (x₂ - x₁)

From the graph, take two points from the graph which are (0, 0) and (27, 6).

Then the unit rate demonstrated in the graph will be given as,

Rate = (27 - 0) / (6 - 0)

Rate = 27 / 6

Rate = 4.5 miles per hour

The unit rate of demonstrated in the graph will be 4.5 miles per hour. Then the correct option is B.

Answer: Infinite solutions

Step-by-step explanation:

This system of equations becomes infinite solutions.

Answer: Potential; Kinetic

Step-by-step explanation:

''...During this process, potential energy has been changed into kinetic energy.''

Potential energy is the energy that a stationery object has because it is stored within the object. In this case the object is the book.

When an object begins to move, it gains kinetic energy which is converted from its potential energy. As the book falls to the floor in this scenario, it gained kinetic energy as its potential energy was converted to enable it move.

Answer:

Step-by-step explanation:

Part A:

Given that the mattress is sold for 50% off of the retail price, let the retail price of the mattress be x, then

50% of x = 1200

⇒ 0.5x = 1200

⇒ x = 1200 / 0.5 = 2400

Therefore, the retail price of the mattress, before the discount is $2,400.

Part B:

Given that the store marks up the retail price to 150% of the wholesale price. Let the whole sale price be p, then

(100% + 150%) of p = 2400

250% of p = 2400

2.5p = 2400

p = 2400 / 2.5 = 960.

Therefore, the wholesale price, before the markup was $960

Answer:

the third one

Step-by-step explanation:

slope intercept form is y = mx + b

where m = slope

for the third one m = 3

therefore the third one is the correct answer

gf(x) = g(x^-1) = x^2 + 6x - 8

f(x) = 2x - 10

gf(x) = 6 ( 2x - 10) - 8

gf(x) = 12x- 60 - 8

gf(x) = 12x -68

gf(5) = gf(x) = 12x - 68

gf(5) = 12(5) - 68

gf(5) = 60 - 68

gf(5) = -8
