Answer:
Step-by-step explanation:
1 grain = 6×10⁻⁶ g
- 7200 kg =
- 7200000 g =
- 7.2×10⁶ g =
- 7.2×10⁶ ÷ 6×10⁻⁶ =
- (7.2÷6)×10⁶⁻ ⁽⁻⁶⁾ =
- 1.2×10¹² grains
Answer:
C. 19.
Step-by-step explanation:
Let's find the answer.
Step 1: divide the first number of 76, which is 7, by 4 and find the integer part.
7/4=1.75, so the integer part is 1.
Step 2: subtract from 7 the (integer part times 4)
7-(1*4)=3
Step 3: put toether the result (3) and the second number of 76, which is 6, so the result is 36.
Step 4: find how many times we need to add 4s to reach 36, so:
4+4+4+4+4+4+4+4+4=36 which means that:
36/4=9
Step 5: put together the two resulted numbers calculated in step 1, which is 1, and step 4, which is 9:
1 and 9 giving 19, so the answer is:
76/4=19.
In conclusion the answer is C. 19.

Answer:
3^10
Step-by-step explanation:
Because the rules of index
3^4 = 3*3*3*3
3^6 = 3*3*3*3*3*3
(3^4)(3^6)=
3*3*3*3*3*3*3*3*3*3 = 3^10
To write a percent as a decimal- move the decimal point two places to the left and divide by 100.
Explanation:
Lets take an example.
We have to convert 25% into decimals.
So, we will divide 25 by 100 , 
Here, we can see that we have moved the decimal to two places on the left side.
