Step-by-step explanation:

Answer:

The perimeter is 14 units

Step-by-step explanation:

Given

[tex]A = (-2,2)[/tex]

[tex]B = (1,2)[/tex]

[tex]C = (1,-2)[/tex]

[tex]D = (-2,-2)[/tex]

Required

Determine the perimeter

To do this, we simply calculate the distance between the sides of the rectangle i.e. AB, BC, CD and DA.

Distance (d) is calculated using:

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

For AB

[tex]A = (-2,2)[/tex] --- [tex](x_1,y_1)[/tex]

[tex]B = (1,2)[/tex] --- [tex](x_2,y_2)[/tex]

[tex]AB = \sqrt{(-2 - 1)^2 + (2 - 2)^2} = \sqrt{9} = 3[/tex]

For BC

[tex]B = (1,2)[/tex] --- [tex](x_1,y_1)[/tex]

[tex]C = (1,-2)[/tex] --- [tex](x_2,y_2)[/tex]

[tex]BC = \sqrt{(1-1)^2 + (2--2)^2} = \sqrt{16} = 4[/tex]

For CD

[tex]C = (1,-2)[/tex] --- [tex](x_1,y_1)[/tex]

[tex]D = (-2,-2)[/tex] --- [tex](x_2,y_2)[/tex]

[tex]CD = \sqrt{(1 - -2)^2 + (-2 -- 2)^2} = \sqrt{9} = 3[/tex]

For DA

[tex]D = (-2,-2)[/tex] --- [tex](x_1,y_1)[/tex]

[tex]A = (-2,2)[/tex]  --- [tex](x_2,y_2)[/tex]

[tex]DA = \sqrt{(-2--2)^2 + (-2-2)^2} = \sqrt{16} = 4[/tex]

So, the perimeter (P) is:

[tex]P = AB + BC + CD + DA[/tex]

[tex]P = 3 +4 + 3 + 4[/tex]

[tex]P = 14[/tex]

The perimeter is 14 units

Answer:

x = 3

Step-by-step explanation:

[tex]x + sin^2 \theta + cos^2 \theta = 4 \\ x + 1 = 4 \\ ( \because \: sin^2 \theta + cos^2 \theta = 1) \\ x = 4 - 1 \\ x = 3[/tex]

Answer:

Total hair cut off  = [tex]\frac{7}{8}[/tex]

Step-by-step explanation:

Given - Ameen went to the salon and had [tex]\frac{3}{8}[/tex] of an inch of hair cut off. The next day she went back and asked for another [tex]\frac{1}{2}[/tex] of an inch to be cut off.

To find - How much hair did she have cut off in all?

Proof -

Given that,

Firstly,

She cut off her hair = [tex]\frac{3}{8}[/tex]

Then,

She cut off her hair = [tex]\frac{1}{2}[/tex]

So,

Total hair cut off = [tex]\frac{3}{8}[/tex] + [tex]\frac{1}{2}[/tex]

                           = [tex]\frac{3 + 4}{8}[/tex] = [tex]\frac{7}{8}[/tex]

⇒Total hair cut off  = [tex]\frac{7}{8}[/tex]

Answer:

Answer:

250π OR 785.398

Step-by-step explanation:

Just plug in the values given to you in the image into the formula for volume.

Your answer can either be 250π or it can be 785.398

Both are correct

Answer:

1277.6

Step-by-step explanation:

Answer:

Below.

Step-by-step explanation:

The dimensions are  5.75m * 6.5 m

= 575cm * 650 cm.

Finding the GCF:

575 = 5 * 5 * 23

650 = 5 * 5 * 26

- so t he Greatest Common Factor of these 2 is 25cm.

575 / 25 = 23

650 / 25 = 26.

So we need 23 tiles along the width of the room and the length will have 26 tiles.

Each tile with be 25cm * 25 cm. in size and the number of tiles = 23*26

= 598.

I don't know what you want , do you want to know how to construct an inscribed angle or what

Answer: 1517.54

Step-by-step explanation:

So we can divide solving this question into two parts: the 2% compound interest and the 5% compound interest.

We know that the compound interest equations is A = P(1+r/n)^nt where:

A is final amount

P is principal (initial) amount

r is interest rate

n is number times interest compounded

t is number of time periods

Given this, in the 2% compound we know:

A = ?

P = 1200

r = 2%

n = 1 (because it didn't say how many times compounded so we assume 1)

t = 2

This becomes:

A = 1200 (1 + (0.02/1))^ 1 * 2

A = 1248.48

Because we switching to 5% from 2%, we can assume that the final amount from the 2% will be the initial amount in the 5%. Thus:

A = ?

P = 1248.48

r = 5%

n = 1

t = 4 (because there were 6 years in total and we used 2 years for 2%)

This becomes:

A = 1248.48 (1 + (0.05/1))^ 1 * 4

A = 1517.54

Answer:

Percentage of cherries    = 60 %

Percentage of berries  = 40 %

Step-by-step explanation:

He orders  15 1/2 pounds every year.

He wants more=  1 1/4 pounds

So the total pounds = 15 1/2 + 1 1/4

                                 = 15 + 1 + 1/2 + 1/4

                                 = 16 + (2+1)/4

                                  =   16 + 3/4

                                  = 16 3/4 pounds

Out of 16  3/4 pounds they want 2/5 part to be of blue berries.

So blue berries = 16 3/4 * ( 2/5)

                          = 67/4 * ( 2/5)

                            = 67/10 = 6 7/10 pounds

Amount of cherries= 16  3/4- 6 7/10

                                 = 10 3/4- 7/10

                                  = 10 (15- 14)/20

                                   = 10 1/20 pounds

Percentage of cherries = Amount of cherries/ Total amount * 100

                                      = 201/20 / 67/4 *100

                                         = 201/20 * 4/67 *100

                                         = 201/335 *100

                                          = 60 %

Percentage of berries = 100- 60 = 40 %

Answer:

36

Step-by-step explanation:

to answer this question :

Volume of a cylinder = nr^2h

n = 22/7

r = radius = 6

h = height = 12

(22/7) x (6^2) x (12)  = 1357.71 in^3

Volume of a cone 1/3(nr^2h)

n = 22/7

r = radius = 3

h = height =

4

(1/3) x (22/7) x (3^2) x (4) = 37.71

1357.71 / 37.71 = 36 times

Answer: other than 7

Step-by-step explanation:

Given

Equation is [tex]x^2+7=x^2+?[/tex]

For an equation to have no solution, the missing number can be any number other than 7

because if we put 7 then it justifies the equation i.e. [tex]7=7[/tex] while on the other hand for a number other than 7, it does not justify the equation.

Answer:

m<4=40

Step-by-step explanation:

Supplementary angles form 180 degrees

m<3 is vertical to the 50 degree angle which is equal.

so. m<3=50

m<5=90

90+50=140

180-140=40

m<4=40
