Area of the given figure is 199.5 square miles.
What is Area?Area of a two dimensional shape is the total region which is bounded by the object's shape.
The given figure can be divide in to smaller figures to find the area of each smaller figure and add it.
A rectangle with sides 5 miles and 3 miles.
A rectangle with sides 15 miles and 6 miles.
A rectangle with sides (8 - 5) + 6 = 9 miles and 3 miles.
A triangle with base length 9 miles and height 8 + 6 + 3 = 17 miles.
Area = (5 × 3) + (15 × 6) + (9 × 3) + (1/2 × 9 × 17)
= 15 + 90 + 18 + 76.5
= 199.5 square miles
Hence the area of the given figure is 199.5 square miles.

(I really need help on this) FGHIJ ~ YUVWX. Find UY and GH.
Answer:
UY = 90
GH = 4
Step-by-step explanation:
Since both figures are similar, the ratio of their corresponding side lengths would be the same.
Thus:
✔️UY/GF = XW/IJ
UY/10 = 54/6 (Substitution)
Multiply both side by 10
UY = (54*10)/6
UY = 90
✔️Also,
UV/GH = XW/IJ
36/GH = 54/6
36/GH = 9
GH = 36/9
GH = 4

What happens to the mean of the data set {10, 2, 8, 9, 5, 2, 6} if the number 12 is added to the data set? A. The mean increases by 2. B. The mean increases by 12. C. The mean increases by 0.75. D. The mean increases by 1.75.
Answer:
C. The mean increases by 0.75.
Step-by-step explanation:
The mean of a data set is given by the sum of all its values, divided by the number of values.
Data set {10, 2, 8, 9, 5, 2, 6}
7 values
Sum: 10 + 2 + 8 + 9 + 5 + 2 + 6 = 42
Mean: 42/7 = 6
Adding number 12 to the data set
Now we have 8 values
The sum is 42 + 12 = 54
The mean is 54/8 = 6.75
This means that the mean increases by 0.75.
Answer:
C. 7.5

A percentage is a way to describe a part of a whole. The correct option is B.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that the colony of 100,000 ants has been declining in number at a rate of 11.4% per month. Therefore, the number of months it will take for the ant population to reach 25,000 ants is,
Population = 100,000(1-0.114)ⁿ
25,000 = 100,000(1-0.114)ⁿ
0.25 = 0.886ⁿ
log(0.25) / log(0.886) = n
n = 11.45335
Since the value is close to 12.2 months.
Hence, the correct option is B.

The model of a shopping mall is made using a scale of 1: 50
If the model of the house is 40 cm tall, calculate the height of the
house in metres.
Answer:
20 m
Step-by-step explanation:
Given that :
Scale of 1 : 50 is used to make a model
If the model has a height of 40 cm ; the height of the house is:
Then, the actual height of the house is (40 * 50) = 2000 cm
Thus the height of the house in metre is :
100cm = 1 meter
2000 cm = 2000 / 100
2000 cm = 20 meter
Height of house in meter = 20 meter

Here a easy one tooooooooooooo
Answer: See explanation
Step-by-step explanation:
1.) There's an angle supplementary to m∠123°, that angle is y
y and m∠123° are supplementary since they're linear pairs
y + 123 = 180
Subtract both sides by 123
y = 57°
Now we know at least two angles of the triangle, x + y + m∠92° has to be 180° because they form a triangle.
x + y + m∠92° = 180°
x + 57 + 92 = 180
x + 149 = 180
Subtract both sides by 149
x = 31°
2.) We have to figure out the missing angle in the triangle, that missing angle is once again, y.
y + 100 + 25 = 180
y + 125 = 180
y = 55°
x and y are supplementary angles because they form a straight line
x + y = 180°
x + 55 = 180
Subtract both sides by 55
x = 125°
Hope I helped!
