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]

The complement of angle M is 10 degrees. What is the measure, in degrees, of angle M?

Answers

Complementary angles add up to 90 degrees.

Let x = complement of angle M is 10 degrees.

We want to solve x + M = 90.

Let's solve for M.

10 + M = 90

M = 90 - 10

M = 80.

The measure of angle M is 80 degrees.

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

Answers

The first question. 7/24

Explanation: first you need to get the fractions to the same denominator so you use lowest common multiples
The lowest common multiple of 8 and 3 is 24 so you times both 3 and 8 by 3 giving you 9/24 and then you times both 1 and 3 by 8 giving you 8/24
When you add these together you get 17/24 so the rest of that would be 7/24

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.)

I hope dis helped :> Bye!!
