Step-by-step explanation:

Betty measured an Italian restaurant and made a scale drawing. She used the scale 2 millimeters : 1 meter. If the actual width of the restaurant's kitchen is 10 meters, how wide is the kitchen in the drawing?

Answers

First convert all the units into millimetres.

1 metre = 1000 millimetres

10 metres = 10000 millimetres

2 : 1000 :: x : 10000

Remember this: Product of means is equal to the product of extremes.

2 × 10000 = 1000x

20000 = 1000x

∴ x = 20000 ÷ 1000

x = 20 millimetres

PLEASE MAKE THIS ANSWER THE BRAINLIEST

Answer:

2 × 10000 = 1000x

20000 = 1000x

∴ x = 20000 ÷ 1000

x = 20 millimetres

What is the area of a triangle?

The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.

From the given figure,

Height of a triangle is 8 units and the base of the triangle is 6 units.

Here, area = 1/2 ×6×8

= 24 square units

Therefore, option B is the correct answer.

4. Find the value of x

Answers

I think it’s 29. I’m not sure but because they’re on a straight line that’s 180 degrees the equation is simple to figure out: 4x+x+35 = 180. Combine like terms, 4x and x, and then you get 5x+35 = 180. Subtract 35 from both sides. Now you have 5x = 145. Divide both sides by 5 to isolate x. That’s how I got x =29.

Answer:

it’s 29.

Hi! Im not sure about the other parts- But i know how to solve for the median!

Step-by-step explanation:

Ok to start off this is your data set.

64 53 60 60 56 58 51 55 60

Then after you place all these numbers in order from least to greatest.

51 53 55 56 58 60 60 60 54

Then you cross them out from side to side till you have the middle number or two numbers in the middle.

58,

So your median is 58!

(I know how to solve for the other ones but i think this is part a)

So i think its this-

Minimum: 51

Median : 53

Maximum: 64

First quartile: 55

Thirf Quartile: 60

( To solve for quartile tiles just say "I crossed out the numbers on each side starting from the median to the minimuk for the first quartile and then the Maximum for the Third quartile.)

The formula to find the surface area (S) of a rectangular prism with a length (l), a width (w) and a height (h) is:

S = 2lw + 2wh + 2lh

What is the surface area, in inches, of a rectangular prism with a length of 5, a width of 4, and a height of 6?

Answers

Answer:

148 in^3

Step-by-step explanation:

S= 2lw + 2wh + 2lh

S = (2 x 5 x 4) + (2 x 4 x 6) + (2 x 5 x 6)

S = 40 + 48 + 60

S = 148

Area of Composite Figures

Answers

Answer:

1) 147

2) 87[tex]m^{2}[/tex]

Step-by-step explanation:

1) Area of triangle = × base length × height

= [tex]\frac{1}{2}[/tex] × 14 × 10

= 70 [tex]m^{2}[/tex]

Area of a semicircle = [tex]\frac{\pi r^{2} }{2}[/tex] ( r is the radius)

Radius = half of diameter = [tex]\frac{14}{2}[/tex] = 7m

Area of semicircle = [tex]\frac{\pi 7^{2} }{2} = \frac{\pi49 }{2}[/tex]

= 77[tex]m^{2}[/tex] ( Nearest whole number )

Total area = 77 + 70 = 147[tex]m^{2}[/tex]

2) Divide the shape into 2 rectangles

Area of a rectangle = length × width

Rectangle 1 = 7 × ( 3+3+5 )

= 7 × 11 = 77[tex]m^{2}[/tex]

Rectangle 2 = 2 × 5

= 10[tex]m^{2}[/tex]

Total Area = 77 + 10 = 87[tex]m^{2}[/tex]
