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]

1) 147

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.)

Answer:

The answer is $420 dollars

Step-by-step explanation:

you times 560 by 25%

that comes to a total of 140/

Ms. Dawson's class raised 25 percent more so you would have to subtract 140 from 560

560-140=420

Find the measure of the missing angles.
X=
Y=
Z=

Answers

Answer:

X= 41

Y= 90

Z= 41

Step-by-step explanation:

X=Z

Y+49=139

Z+Y+49=180

X+139=180

139+49+X+Z+Y=180

These we know because of the placement of the angles.

Using this information, we can solve this in numerous ways. I'm going to solve it using one of them. Making both sides equal to 180 and then checking my work by adding all of the numbers I get together to make sure that they equal 360.

X+139=180

X=41

X=Z.

49+Z+Y=180

49+41+Y=180

90+Y=180

Y=90

Thus,

X= 41

Y= 90

Z= 41

To check, let's add them all together.

41+90+41+139+49=

360

This is correct!

X=41
Y=90
Z=41

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
