Answer:
You write the non-zero digits, placing a decimal after the first non-zero digit. Then, you count the number of digits you need to move the beginning decimal to get to where your decimal is now. If you move the decimal to the left, then your power is positive.
Step-by-step explanation:
so for example, .005 would be 5x10^-2 and 500 would be 5x10^2
Answer:
2 of these numbers are divisible by 4 and 5.
20 and 60 are divisible by 4 and 5.
Step-by-step explanation:
20 is divisible by 4 and 5.
Divisible just means that the 4 (also the 5) goes into 20 evenly, with no remainder.
4 goes into 20 evenly with no remainder.
5 goes into 20 evenly with no remainder.
4 does not go into 35 evenly with no remainder.
35 ÷ 4 is 8 with a remainder of 3.
35 ÷ 4 = 8.75
5 does go into 35. 35 is divisible by 5.
35 is not divisible by 4.
60 is divisible by 4
60 ÷ 4 = 15 (no remainder, no extra decimals if you do it on a calculator)
60 ÷ 5 = 12 (no remainder, no extra decimals if you do it on a calculator)
60 is divisible by 4 and also by 5.

Step-by-step explanation:
Answer:
11
Step-by-step explanation:
Let's call the white marbles w and the red marbles r. We can write:
w + r = 16 (1)
w = 3r - 4 (2)
3r - 4 + r = 16 (3) (Substitute (2) into (1))
4r = 20 (simplify)
r = 5 (divide by 4) which means w = 16 - 5 = 11
