Answer:
1.3905 × 10^4
Step-by-step explanation:
First you should multiply all the two numbers inside the parentheses
5.7 × 105=598.5
4.6 × 106=487.6
2.9 × 105=304.5
Now add the three numbers
598.5+487.5+304.5= 1390.5
scientific notation: Put the decimal after the first digit. To find the exponent count the number of places from the decimal to the end of the number.
the answer in scientific notation: 1.3905 × 10^4
There are 365 days in a year.
So in 4 years, there are 365 × 4 = 1460 days.
However, every 4 years, there is also a "leap day." (an additional day in February of years divisible by 4 to balance the calendar)
After adding this day, we would have 1461 days in 4 consecutive years.
<em>
</em><em>*Note: There are exceptions to when leap years happen, so on some 4 year periods there is no leap year. In that case, there could be just 1460.</em>

Answer:
100 liters of 10% solution is used and 20 liters of 40% solution is used
Step-by-step explanation:
Let "X" amount of 10% solution is used. Then the amount of 40% solution used is equal to 120-X
Now
10% of X + 40% of (120-X) = 15% of 120
On solving the above equation, we get
liters
Amount of 40% solution used = 120 -X = 120-100 = 20 liters
100 liters of 10% solution is used and 20 liters of 40% solution is used
