Step-by-step explanation:
No,The room is not a square shaped.This is because.Perimeter of the square shape would be length of any sides×4 as all sides will be the same in a square.Therefore, if the room ia a square, the 4 sides of room floor will be equal too.It is not a square shaped room beacause it sides are not equal for floor.We can determine by finding the sides;
diagonal is 18.75 so by using pythagoras theorem
diagonal^2 =l^2 + b^2
b^2=18.75^2 + 17^2
b =25.31 inches which is not the same as the length 17 inches.Therefore,the room is not a square
Answer:
5√5
Step-by-step explanation:
Hypotenuse (h) = 15
perpendicular (p) = 10
base (b) = ?
We know by using Pythagoras theorem
b = √h² - p²
= √ 15² - 10²
= √ 125
= 5√5
Hope it will help :)
Answer:
The amount of time it takes Shelly to clean each house is 3.6 hours or 2 hours 36 minutes.
Step-by-step explanation:
Shelly cleans 5 different houses in 18 hours.
To compute the amount of times Shelly spends cleaning one house divide the total hours spend by the number of houses cleaned.
The number of hours it takes Shelly to clean a single house is:
Number of hours spent cleaning 1 house = 
hours.
Thus, the amount of time it takes Shelly to clean each house is 3.6 hours or 2 hours 36 minutes.
