plssss help me asap

use multiplication to solve the proportions​

Answer:

x + 90 + 63 = 180

Step-by-step explanation:

∠A + ∠B + 45 + 63 = 180     {Straight line angles}

From the figure we know that , ∠B + 45 = 90

Therefore, ∠A + 90 + 63 = 180

Answer:

Option B is correct.

Step-by-step explanation:

∠A = 27

27 + 90 + 63 = 180

you can see that square right. the square is 90.

Have a nice day!

Answer:

9,8 kg

3 kg + 2,5 kg + 2,5 kg + 1,8 kg = 9,8 kg

Answer: 9,8 kg

Answer:

choose to places and with this formula, you can find it easily;

(y_2 - y_1)/(x_2 - x_1)

first place can be (1, 3) and the second can be (2,5):

5-3/2-1 =2

and it would be 2

Answer:

1st Equation: -8x + y = 22

At (-2,6)

(-8*-2)+ 6 =16+6= 22: That is correct

2nd Equation: -8x - y =10

At (-2,6)

(-8*-2)-6= 16-6= 10: That is correct

Both are correct.

Hope it helps you.

Answer:

The median is 58

Step-by-step explanation:

Answer:

The answer is 58

Answer:

Step-by-step explanation:

Portrait is in the shape of a rectangle.

And the area of a rectangle = Length × Width

Let the length of the portrait = l

And width of the portrait = w

Area of the portrait = lw

lw = 40

l = [tex]\frac{40}{w}[/tex]

Perimeter of a rectangle = 2(Length + width)

Perimeter of the portrait = 2(l + w)

26 = 2(l + w)

l + w = 13 ----------(2)

By substituting the value of 'l' in equation (1) from equation (2)

[tex]\frac{40}{w}+w=13[/tex]

40 + w² = 13w

w² - 13w + 40 = 0

w² - 8w - 5w + 40 = 0

w(w - 8) - 5(w - 8) = 0

(w - 5)(w - 8) = 0

w = 5, 8 feet

From equation (2)

l = 8, 5 feet

Therefore, dimensions of the portrait are (5 feet by 8 feet) Or (8 feet by 5 feet).

Answer:

D)

A = x(x + 4)

Step-by-step explanation:

Area of a rectangular map = width × length

Length of the rectangular map = (x + 4) miles

Width of the rectangular map = x miles

Area of a rectangular map = width × length

= x(x + 4)

= x² + 4x

D)

A = x(x + 4)

Answer: edge 2021

Step-by-step explanation:

Answer:

y = 6x

Step-by-step explanation:

Equation representing the relation between duration of work and earning is,

y = kx

Here, y = earnings

x = Working hours

k = Proportionality constant

By substituting the values in the given equation,

x = 25 hours

y = $150

150 = k(25)

k = 6

Therefore, equation modeling the situation will be,

y = 6x

Answer:

1/10

Step-by-step explanation:

First, convert your numbers to decimals.

2.5 cans of paint cover 0.25 area of a room.

Equation:

2.5=0.25

If you divide 2.5 by 5, you'll get 0.5.

But what you do to one side, you do it to the other.

0.25÷5= 0.05

So now you have your new equation

0.5=0.05

since you want 1 can of paint, multiply it by 2.

1= 0.1

convert it back to fraction: 1/10

Step-by-step explanation:

A = -7.

B = -8 x-(-6) is the same as x + 6

C = 13

D = 2

E = -3

Answer:

Step-by-step explanation:

plug the equations into Desmos

as attached

y = -3x-6

x + 3y = 6

3y = -x +6

y = -1/3x +2

-3x-6 = -1/3x +2

-8/3x = 8

x = - 3

y=-3(-3)-6

y = 9-6

y = 3

Answer:

15x + 12

Step-by-step explanation:

3(5x + 4)

15x + 12

3 · 5x = 15x

3 · 4 = 12

Combine them:

15x + 12

Answer:

3(5x + 4)

15x + 12

3 · 5x = 15x

3 · 4 = 12

Complete question :

A video game developer wants to know how long it takes people to finish playing their new game. They surveyed a random sample of 13 players and asked how long it took them (in minutes).

1235

952

457

1486

1759

1148

548

1037

1864

1245

976

866

1431

Estimate the median time it will take all players to finish this game.

Find the interquartile range for this sample.

Answer:

1148 ; 549.5

Step-by-step explanation:

The ordered data:

457, 548, 866, 952, 976, 1037, 1148, 1235, 1245, 1431, 1486, 1759, 1864

The median value :

1/2 * (n +1)th term

n = 13

1/2 * 14 = 7th term

Median = 1148

The interquartile range :

Q3 - Q1

Q3 = 3/4(n+1)th term

Q3 = 3/4 * 14th term

Q3 = 10.5 th term

Q3 = (10 + 11)th term

Q3 = (1431 +1486) / 2= 1458.5

Q1 = 1/4(n+1)th term

Q1 = 1/4 * 14th term

Q1 = 3.5 th term

Q1 = (3 + 4)th term

Q1 = (866+ 952) / 2= 909

IQR = 1458.5 - 909 = 549.5

Answer:

Median:1054 mins

IQR:751.5
