The area of the composite figures are as follows;
10. Area of the trapezoids are; 96 cm², 80 cm², 96 cm², 80 cm²
Area of the rectangle at the center = 320 cm²
11. Area of the field on the left is 18,600 m²
Area of the field on the right is 11,000 m²
What is a composite figure?A composite figure is a figure that consists of two or more regular shapes.
10. The width of each trapezoid are;
(28 - 20)/2 = 4
(24 - 16)/2 = 4
The area of each trapezoid are;
The area of each of the left and right trapezoid = 4 × (20 cm + 28 cm)/2 = 96 cm²
Area of the top and bottom trapezoid = 4 × (16 cm + 24 cm)/2 = 80 cm²
Area of the rectangle at the center = 16 cm × 20 cm = 320 cm²
11. Area of ΔDEI = 0.5 × 80 m × 60 m = 2400 m²
Area of trapezoid EIGF = 0.5 × (60 m + 50 m) × (60 m + 20 m) = 4400 m²
Area of the triangle ΔAGF = 0.5 × 50 m × 80 m = 2000 m²
Area of ΔAHC = 0.5 × 40 m × (20 m + 80 m) = 2000 m²
Area of ΔABC = 0.5 × 30 m × (20 m + 80 m) = 1500 m²
Area of quadrilateral AHCB = 2000 m² + 1500 m² = 3500 m²
Area of triangle ΔCDH = 0.5 × 40 m × (80 m + 60 m) = 2800 m²
Adding together, we get;
2400 + 4400 + 2000 + 2000 + 1500 + 3500 + 2800 = 18,600
The area of composite figure is 18,600 m²\
Area of ΔEFH = 0.5 × 20 m × 40 m = 400 m²
Area of trapezoid GFHJ = 0.5 × (20 m + 40 m) (40 m + 40 m) = 2400 m²
Area of triangle ΔAGJ = 0.5 × 40 m ×(20 m + 60 m) = 1600 m²
Area of triangle ΔABK = 0.5 × 30 m × 60 m = 900 m²
Area of trapezoid BCF_K = 0.5 × (40 m + 30 m) × (40 m + 20 m) = 2100 m²
Area of triangle ΔCIE = 0.5 × 40 m × (40 m + 40 m) = 1600 m²
Area of triangle ΔCDE = 0.5 × 50 m × (40 m × 40 m) = 2000 m²
Adding the areas together, we get;
400 + 2400 + 1600 + 900 + 2100 + 1600 + 2000 = 11000
The area of the field is 11,000 m²

How do you know which number is the largest when you compare integers?
Answers
Answer:
Step-by-step explanation:
Lets take 4905 and 802
Firstly to figure out which of these two numbers is bigger we first look at the highest place value that either one of these two numbers have
In this case its 4 in the thousands place in the number 4905
Next we look at which number 802 has in the thousands place
In this case there is no number or 0
4 is bigger than 0 so we know that 4905 is bigger than 802
Lets take another example
4905 and 8204
Here both numbers have a number in the thousands place on is 8 and the other is 4
8 is bigger than 4 so 8204 must be larger
I'm just saying comparing integers should come very easily and you really don't need to think much to figure this out
I'm guessing you mean how do you compare numbers which are non-integers like 4/6 or 4/5 and this is quite easy
There are multiple ways but one method is to just multiply the denominator of one fraction with the numerator of the other and do the same for the other fraction
lets take 4/6 and 4/5
4*5=20
and 4*6= 24
4/6 we can assign 20
and 4/5 is 24
the bigger number is 24 so 4/5 is bigger

The U.S. Department of Labor reports that the average prices for a dozen eggs in the month of May for the past 11 years are as follows: $1.19, $1.21, $1.50, $1.93, $1.50, $1.52, $1.69, $1.69, $1.87, $2.00, $1.96 Round to the nearest hundredth (cent) if necessary. The mean price of eggs over this 11-year period is The median price of eggs over this 11 -year period is
Answers
Answer:
Mean price of eggs = $1.64
Median price of eggs = $1.69
Step-by-step explanation:
Mean is the average of the given data
Mean = sum of data/sample size
Sum of data = 1.19+1.21+1.50+1.93+1.50+1.52+1.69+1.69+1.87+2.00+1.96
Sum of data = $18.06
Sample size = 11
Mean price of eggs =18.06/11
Mean price of eggs = $1.64
Hence the mean price of eggs over this 11-year period is $1.64
Median is the price in the middle after rearrangement
Rearranging the data
1.19, 1.21, 1.50, 1.50, 1.52,) 1.69, (1.69, 1.87, 1.93, 1.96, 2.00
Since 1.69 falls in the middle after rearranging;
Hence the median price of eggs over this 11 -year period is $1.69

The ratio of the length to the width to the height of an open rectangular tank is 10: 5: 8. The height is 18 feet longer than the width. What is the volume of the tank
Answers
Answer:
hi
Step-by-step explanation:
how are you
Answer: A: L: W: H = 10: 5: 8
Step-by-step explanation: The height of the tank is 18 feet longer than the width
H = 8 parts, W = 5 parts => 8 – 5 parts = 18 feet i.e. 3 parts = 18, 1 part = 6 feet
Hence, L = 10 * 6 = 60 feet
W = 5 * 6 = 30 feet
H = 8 * 6 = 48 feet
Volume = 60 * 30 * 48 = 86400 ft³
Surface Area = 2 * (30 * 60 + 48 * 60 + 30 * 48) =12240 ft²

WILL BE MARKED BRAINLEIST!
Answers
Answer:
1. We want to write an equation in the form:
Ix - bI ≤ c
Such that the solutions are the range −1 ≤ x ≤ 3
First, the extremes of the range are: - 1 and 3
Half of the difference between these values is:
m = (3 - (-1))/2 = (3 + 1)/2 = 4/2 = 2
Now let's go to the lower extreme, and add this value, we get:
-1 + m = -1 + 2 = 1
(if we go to the upper value and we subtract m, we get the same)
This is the mid-value of the solution interval, and we will define it as M
We now can write the absolute value inequality as:
I x - MI ≤ m
In our case, we get:
Ix - 1I ≤ 2
2.
Now we want to have the solution set given by:
x ≤ -9
x ≥ -5
In this case, we will have an equation of the form:
Ix - MI ≥ m
(before we used the symbol ≤, which means that the solutions are inside the interval, now we use the symbol ≥, which means that the solutions are outside of the interval (-9, -5) in this case).
So let's do the same than in the above case:
m = (-5) - (-9) = (-5 + 9)/2 = 4/2 = 2
M = -9 + 2 = -7
Replacing these in the absolute value inequality we got:
Ix - (-7)I ≥ 2
Ix + 7I ≥ 2
Solve for x . x/2 + 1.1= -2.1
Answers
Answer: x = 1.6
Step-by-step explanation:
Start by Identifying what you need to keep, in this case that would be X. In order to solve for x, you would need to get rid of any co-efficients. (example: +1.1) To get rid of them, you have to do the opposite action of what it's doing to the equation. (subtraction)
1.1- (-2.1) = 3.2 (if you subtract a negative, it turns positive/ you add) leaving you with x/2 = 3.2.
Now that we have our coefficient out the way, we have to get rid of the division so we can only solve for x. We do that by dividing the remainder of the equation by 2
3.2/2 = 1.6
Leaving us with the answer, x = 1.6

b. What transformation maps square 2 onto square 3?
c. What transformation maps square 1 onto square 5?
Answers
Answer:
A) Translation
B) Reflection
C) Rotation
Step-by-step explanation:
The transformation types in mathematics are;
Reflection, translation, rotation and dilation.
We can see that the squares are all the same size, it's just the position of the stars that will aid us in knowing the specific transformation.
A) We can see that square 2 is the exact same thing as square 1. Just that it was shifted to the right of square 1. Thus, it was translated and the transformation is translation.
B) We can see that the star in square 3 is the exact mirror copy and location from square 2. Thus, this is a reflection.
C) We can see that the position of the star in square 5 is top while that in square 1 is at the left corner. This can only be achieved by rotation.
