Problem 1:
To find the area you must use the formula A = (b_1 + b_2)h/2, so you do (175 + 185)100/2 which is 360*50 = 18000cm².
A = 18000 cm²
Problem 2:
Just use the shown formula, so it would be 40/100 = x/Area, 40*18000/100 = 40*180 = 7200cm²
Available lot coverage = 7200cm²
The area of the trapezoid is 18000 square units.
The area available for lot coverage is 7200 square units.
What is a trapezoid?A trapezoid is a four-sided shape that has one pair of sides parallel.
We have,
Area of a trapezoid:
= 1/2 ( a + b ) h
a and b are the two parallel sides.
h = height of the trapezium.
We have,
a = 175
b = 185
h = 100
Area of a trapezoid:
= 1/2 x ( 175 + 185 ) x 100
= 1/2 x 360 x 100
= 18000
We will calculate 40% lot coverage of the 18000 area.
40% = 40 / 100
So,
= 40/100 x 18000
= 7200
Thus,
The area of the trapezoid is 18000 square units.
The area available for lot coverage is 7200 square units.

The length of a side of an equilateral triangle is x−4.5.
First, express its perimeter as a sum.
Next, express its perimeter as a product.
Answer:
The sides of an equilateral triangle are same. So if one of the sides is (x-4.5), all the sides are (x-4.5).
Let the sides are a=(x-4.5), b=(x-4.5), c=(x-4.5)
1. Perimeter(as sum) = a+b+c
= (x-4.5)+(x-4.5)+(x-4.5)
= x+x+x-4.5-4.5-4.5
= 3x - 13.5
2. Perimeter (as product) = 3×a
= 3×(x-4.5)
= 3×x - 3×4.5
= 3x - 13.5
(you can write 3×b or 3×c also as a=b=c.)
Both perimeter as sum and perimeter as product are same as adding a number three times is the same as multiplying it by 3.

help and explain how you got it.
no trolling or report!
Answer:
I am 100% confident in my calculations. I'm not 100% sure about interpreting. Sorry I can't be of more help.
Part A:
Median: 4.5
IQR: 3.5
Mode: 6
I think the median/IQR is a better measure of center and variability because the range of data is so big (10 - 0 = 10), and the data skews to the right with the 6s.
Part B:
I would say no. It is the one that occurs most frequently, but there are many more times she rides less than 6, which is why the median is 4.5
Step-by-step explanation:
Mean: 4.714
MAD: 2.43
Median: 4.5
IQR: 3.5
Mode: 6
the number set in order:
0, 2, 2, 2.5, 2.5, 3, 4, 5, 6, 6, 6, 8, 9, 10
The median (middle number) is two numbers: 4 and 5, so the median is 4.5
The first quartile/Q1 (middle of the bottom half of data) is 2.5, the third quartile/Q3 (middle of the top half of data) is 6. So the IQR (interquartile range) is 6 - 2.5 = 3.5
The mean is the sum of the numbers divided by the quantity of the numbers, so 66/14 = 4.714
the mean absolute deviation is found by calculating the mean, and then finding the absolute value of the difference between each number of the set and the mean...then adding those together and finding the mean of that set. Labor intensive, but that's 34/14 = 2.42857143

What is the LCD of 8/21 and 2/7?
Answer:
21
Step-by-step explanation:
7 can go into 21
Answer:
21
Step-by-step explanation:
Equivalent Fractions with the LCD
8/21 = 8/21
2/7 = 6/21
Solution:
Rewriting input as fractions if necessary:
8/21, 2/7
For the denominators (21, 7) the least common multiple (LCM) is 21.
LCM(21, 7)
Therefore, the least common denominator (LCD) is 21.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
8/21 = 8/21 × 1/1 = 8/21
2/7 = 2/7 × 3/3 = 6/21

Mrs. Stephan took her children to pick out pumpkins. Cater picked out a pumpkin priced $20, and Isabel picked out a pumpkin priced $13. How much did Mrs. Stephan pay for both pumpkins, including 7% sales tax?
Answer:
$35.31
Step-by-step explanation:
(20+13) x (1+0.07) = 35.31
You add the price of both pumpkins together to get the price of the pumpkins before tax. Then you multiply it by (1 + 0.07) because 1 is the regular price plus the sales tax which is a percent that can be converted to decimal to 0.07. You multiply these together and get 35.31
Answer:
$35.31

Answer:
Apply the distributive property to the left-hand side of the inequality.
Step-by-step explanation:
Using PEMDAS, what you need to do first is clear!
P -> parentheses ( distribute, clear them out, etc. )
E -> exponents
M -> multiplication
D -> division
A -> addition
S -> subtraction
Going in order, you would apply the distributive property first to clear out the parentheses.

The value of d in the given expression is 2/5.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
We are given an expression as
3/2 = 5d - 1/2
we need to solve for d;
3/2 = 5d - 1/2
5d = 3/2 + 1/2
5d = 4/2
5d = 2
d = 2/5
Hence, the value of d in the given expression is 2/5.
