Answer:
6 hours
Step-by-step explanation:
Let the total work be X
Combined speed: X/2
Ron's speed: X/3
Harry's speed: S
X/2 = X/3 + S
S = X/2 - X/3 = (3X - 2X)/6 = X/6
Harry's speed is X/6, so he'll take 6 hours
Answer:
260 square feet
Step-by-step explanation:
The area of a rectangle is given by the formula ...
A = LW
The area of two same-size rectangular rooms will be double the area of one of them.
__
<h3>room area</h3>
Each room has an area of ...
A = LW = (13 ft)(10 ft) = 130 ft²
<h3>carpet order</h3>
The order for carpet must be for 2 times the area of one room:
carpet order = 2 × 130 ft² = 260 ft²
Jerry should order 260 square feet of carpet.
consider the numbers are x,2x,3x,4x,5x
Given;
(x+2x+3x+4x+5x)/5 = 11
15x = 55
x= 55/15 = 11/3
The numbers are
11/3, 22/3, 11, 44/3, 55/3
