Answer:
800
Step-by-step explanation:
Repeated multiplication can be written as *exponentiation*. Here, 3.6 is multiplied by itself 4 times, so we would rewrite it as (3.6)^4 (in writing, you’d see it as 3.6 with a small 4 written to the upper right of the number)
1: down 1, over 4 (-1/4)
2: up 2, over 3 (2/3)
3: down 3, over 3 (3/3 or 1)
4: undefined ( because all the points on the line have the same x value)
5: 0 ( because x can be any value)
6: 5/3
7:6/-12 or 1/-2
8: -12/4 or -3
9: 12/-10 or 6\-5
10: -4/-1 or 4
11: 0/15
12: -3/4
13: 8/4 or 2
14: 11/0
calm down and try to complete the questions
You can set up an equality:
40/160 = 225/x
Cross multiply:
40x = 160(225)
Evaluate:
40x = 36000
Isolate x:
x = 900.
So, 900 batteries are required for 225 calculators.
Hope this helped!! xx
