The first stone will be 10-in wide
The last stone will be 10-in wide
The stones in the middle will be alternating between 5-in and 10-in stones, making a total of 15-in
Total width = 145-in
Width after placing first and last stones = 145 - 20 = 125-in
Number of 15-in patterns incorporated in 125-in:
125/15 = 8.33
Therefore, he will place 8 10-inch stones within and 9 5-inch stones within the patter.
The total 10-inch stones used = 8 + 2 = 10
Answer:
14.652c-21.22b
Step-by-step explanation:
multiply parentheses by -1.01
9.4c-22.22b+5.252c+b
collect like terms
14.652c-21.22b
Answer:
The radius of the larger is 3 3/5 cm or 3.6 cm
Step-by-step explanation:
The ratio of the volumes is that is related to the scale factor cubed
125/216 = (sf) ^3
Taking the cube root of each side
(125/216)^1/3 = (sf) ^3 ^(1/3)
5/6 = (sf)
That means the ratio of the radii is in the same proportion
5/6 = 3/ r
Using cross products
5r = 6*3
5r/5 = 18/5
r = 18/5 = 3 3/5
