The perimeter of the octagon is 8 times the side
p=25*8=200 cm
200cm=2 m
Answer:
a) independent = hours
dependent = wages
b ) W = 10 + 5h
c)27.50
Step-by-step explanation:
The independent variable is the one that you change which is the number of hours that it takes
The dependent variable is the variable that changes based on the independent variable. The wages depends on the hour worked so the wages are the independent variable
The wages equal the fixed cost plus the hourly rate times the number of hours where W is the wages and h is the number of hours
W = 10 + 5h
W = 10 + 5( 3.5)
= 10 + 17.5
= 27.5
Use one of the many Trigonometric ratios to solve for the missing angle and then use Pythagorean theorem to solve for the missing side.
These things can be done in any order.
30 because 18 and the plain goes into 12 which is 30

Answer: Hassan's expression:
d = original price
0.25d = amount of discount
d-0.75d= sale price of the book
Bella's expression
0.75d = sale price of a book
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
d = original price in dollars
25% off = 0.25 in decimal form ( 25/ 100 = 0.25)
Hasan's expression:
d−0.25d
In this expression 0.25d is the amount of discount , and d is the original price.
For example :
If a book costs $100 (original price) :
sale price =100 - (0.25 x 100)
sale price=100- 25
sale price=75
Bella's expression:
0.75d
in this expression 0.75d is the sale price ( d is the original price and since the percent discount is 0.25 it can be expressed as a 0.75 of the original price since 100-25=0.75)
