There is an average of 3.5×10−2 kilograms of dissolved salt in each liter of seawater. The South China Sea contains approximately 9.88×1018 liters of seawater. How many kilograms of dissolved salt are in the South China Sea? Enter your answer, in scientific notation, in the boxes.
Answers
Answer:
3.458×10¹⁷ kg
Step-by-step explanation:
(3.5×10⁻² kg/L) × (9.88×10¹⁸ L) = (3.5×9.88) × 10⁽⁻²⁺¹⁸⁾ kg
... = 34.58×10¹⁶ kg
... = 3.458×10¹⁷ kg
_____
Comment on significant digits
It would be appropriate to round the answer to 2 significant digits, matching the number of significant digits in the least-precise factor. Then the answer would be 3.5×10¹⁷ kg.

6 apples each and the bags with mangoes
contain 3 mangoes each. If David and his
friends ate 2 apples from each bag and 2
mangoes from each bag, what is the total
number of fruits left over?
Answers
Answer:
Step-by-step explanation: the step by step explanation is 6*4=24 so 24 apples then 3*2=6 so 6 mangoes then if 8 apples are ate then 4 mangoes are ate then (24+6)-(8+4)=30-12 so the answer is 18.
6 bags in total
4 bags x 6 apples each = 24 fruits
2 bags with 3 mangoes each= 6 fruits
Total 30 fruits
Friends ate 2 fruits from each of the 6 bags
They ate 12 fruits
30-12 = 18

The doublePennies() function is an illustration of a recursive function in Java
How to complete the doublePennies() function?
The base case of the doublePennies() function is that:
When the number of days is 0, then the total available pennies is the same as the total number of pennies.
The algorithm of the above highlight is:
if numDays equals 0 then
totalPennies = numPennies
Using the above algorithm, the complete base case is:
if(numDays == 0){
totalPennies = numPennies;
}

The linear function that models this situation is:
- The y-intercept is y = 3000, which means that when there is no increase on the price, the farm sells 3000 gallons.
- The x-intercept is x = 6, which means that if the price increases $6, no gallons will be sold.
- The slope is of -500.
- The graph is sketched at the end of this answer.
The equation of a line has the following format:
In which:
- a is the slope, which is by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
In this problem, m(0) = 3000, thus, , that is:
- The y-intercept is y = 3000, which means that when there is no increase on the price, the farm sells 3000 gallons.
The amount decreases 500 gallons for every $1 increase in price, thus, the slope is -500, and the equation is:
The x-intercept is the value of x for which:
Then
- The x-intercept is x = 6, which means that if the price increases $6, no gallons will be sold.

Answer:
Slope of the graph gallons per dollar.
Intercept is 3000.
Step-by-step explanation:
General format of an equation of a linear graph is;
y=mx+c
Where,
y is the dependent variable
m is the slope of the graph
x is the independent variable of the graph
c is the intercept of the graph.
m(0)=3000 means when we substitute 0 for x values of the graph the y value is 3000. Therefore the intercept is 3000.
Slope of the graph =
= gallons per dollar.
So we can write the equation as;
but in this question y is given as m. Therefore function can be re-written as:
