Answer: $1125
Step-by-step explanation:
He works five days a week so it would be 225 times 5 which equals 1125
Look at the prime factorization. If all the factors have powers that are multiples of 6, then the number is a square and a cube. If they are multiples of 3, then a cube; if multiples of 2, then a square.
1000 = 2³·5³ . . . . a perfect cube
4 = 2² . . . . a perfect square
120 = 2³·3·5 . . . . none of the above (not a square or a cube)
36 = 2²·3² . . . . a perfect square
100 = 2²·5² . . . . a perfect square
49 = 7² . . . . a perfect square
125 = 5³ . . . . a perfect cube
25 = 5² . . . . a perfect square
Convert the decimal number to a fraction by placing the decimal number over power of ten. Since there are 3 numbers to the right of the decimal point, place the decimal number over 10^3 (1000). Then, add the whole number to the left decimal.
