Area of Composite Figures
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]
Answer:
1) 147
2) 87

Segment CD will be parallel to segment C'D'. And the area and perimeter of the shape will remain the same. Then the correct options are B, D, and E.
What is a transformation of a shape?The translation does not change the shape and size of the geometry. But changes the location.
Suppose translating quadrilateral ABCD by 8 units to the left and 8 units down results in a new quadrilateral A'B'C'D'.
In the translation, the position is changed only but the dimension of the shape does not change.

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

Answer:
2/3(3/4x-3/2) = 1/2x-1
(2x+1) - (x+3/2) = x - 1/2
Step-by-step explanation:
1) Distribute 2/3 to both 3/4x and -3/2
2/3(3/4x) = 6/12x which can be simplified as 1/2x
2/3(-3/2) = -6/6 which simplifies to -1
2/3(3/4x-3/2) = 1/2x-1
2) (2x+1) - (x+3/2) combine like terms
2x-x = x
1 - 3/2= 1- 1 1/2 ( change 3/2 into an improper fraction. 2 goes into 3 one time with one left over. Place the “leftover” back on top of the original denominator of 2)
1- 1 1/2 = -1/2, so
(2x+1) - (x+3/2) = x - 1/2

Answer:
The answer is $420 dollars
Step-by-step explanation:
you times 560 by 25%
that comes to a total of 140/

Answer:
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.)

Oscar spent two thirds hour each night doing homework for five nights this week. How many hours of homework did Oscar complete this week?
seven and one half hours
three and one third hours
two and one third hours
one and one fifth hours
Answer:
The answer is 7.5 hours.
Step-by-step explanation: This is because if he spent 2/3 of every night doing homework for five days then he would spend a lot more than 3 hours and the other answers are even below 3 so thats gotta be incorrect.
Hope this helps.
Answer:
The answer is three and one third hours
Step-by-step explanation:
If Oscar spent two thirds an hour for five nights doing homework, then we would have night one is two thirds, the next night he spent one and one third, the next night would be 2 hours total, then the next night would add another 2/3 making it 2 2/3, finally the last night is two thirds of an hour making it a total of 3 and 1/3 hours spent on homework that week.

Part C.) A landmark on the first map is a triangle with side lengths of 3 mm, 4 mm, and 5 mm. What are the side lengths of the triangle landmark on the second map? Show your work. It may help you to “draw” out the two maps and label the trails. (3 points)
Answer:
Scales are used on maps in the same way that they are used in plans.
A scale of 1 : 50 000 is used on many Ordnance Survey maps.
This means that 1 cm on the map represents an actual distance of 50 000 cm (or 500 m or 0.5 km).
Converting measurements on a map
We saw above that if a map has a scale of 1 : 50000, then 1 cm on the map is 50000 cm in real life.
(a) Imagine we have measured a distance as 3 cm on this map, and we want to find out how far this is in real life.
To work out the distance in real life, we need to multiply this length by 50000.
This gives 3 cm × 50000 = 150000 cm which is 1500 m or 1.5 km.
Alternatively, we could have just remembered that each 1 cm on the map is 0.5 km in real life.
Hence, 3 cm on the map must be 3 × 0.5 km = 1.5 km in real life.
(b) Now imagine we want to walk 4.5 km in real life, and we need to find out how far this is on the map.
To work out the distance on the map, we need to divide this length by 50000.
4.5 km = 4500 m = 450000 cm. Dividing 450000 cm by 50000 gives a distance on the map of 9 cm.
Alternatively, we could have just remembered that each 0.5 km in real life is 1 cm on the map.
If we divide 4.5 km by 0.5 km we get 9, so the distance on the map must be 9 cm.

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?
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
