Answer:
1 / 3^5
1/ 243
Step-by-step explanation:
3^4 ÷ 3^9
We know that a^b ÷ a^c = a^ ( b-c)
3 ^ ( 4-9)
3^ -5
We can rewrite this as a^-b = 1/ a^b
1 / 3^5
We know that 3^5 = 243
1/ 243
It was $930.
To over check, multiply it by 20% , you will get $186.
Hope this helps !
Given that Sienna planned a rectangular pool drawn on a scale 11 inches long by 7 inches wide, and Sienna used the scale drawing above to create a pool that is 14 ft wide x 22 ft long, and she then decided to make a pool with a final length of 33 ft, to determine which expression finds the change in scale factor for the longer pool Sierra is building the following calculation must be performed:
- 11 inches = 0.916 feet
- 11 / 0.916 = 12
- 7 inches = 0.583333 feet
- 7 / 0.5833333 = 12
- Thus, the initial scale is 1:12.
- 33 / 0.916 = 36
Therefore, the scale factor went from 1:12 to 1:36.
