a. 202.5g
Since 45% of the energy drink is sugar
⇒ 45% of the total 450 grams will be made up of sugar
∴ sugar = 
* 450
= 202.5g
Thus, the can contains 202.5g of sugar
b. 3.2L
Since Simon used up 20% of the paint, the paint left in the can will now be 80% of the original 4 liters
∴ paint left = 
* 4
= 3.2L
Thus, the can has 3.2 liters of paint left.
c. 1680 acres
Here, 30% of the farmer's crop is and the rest is wheat
⇒ 70% is wheat
Total acres of land planted= 2400
∴ Acres planted with wheat = 
*2400
= 1680 acres
Thus 1680 acres is planted with wheat

Answer:
The coordinates of the point on a circle with radius 4 at an angle of 
radians are x = -2 and y = 3.464.
Step-by-step explanation:
This problem ask us to determine the rectangular coordinates from polar coordinates. The polar coordinates of the point in rectangular form is expressed by the following expression:
Where 
and 
are the radius of the circle and the angle of inclination of the point with respect to horizontal, measured in radians. If 
and 
, the coordinates of the point are:
The coordinates of the point on a circle with radius 4 at an angle of radians are x = -2 and y = 3.464.
You need 3a^3 to equal a^3, so you would need at subtract 2a^3.
Since the problem is addition, add - 2a^3:
3a^3 + -2a^3 = 3a^3 - 2a^3 = a^3
Then you have -5b^3 and you need it to equal b^^3, so you would need to add 6b^3:
-5b^3 + 6b^3 = b^3
First box would be -2
Second box would be 6
The expected gain or loss is an illustration of mean and expected values.
The expected total gain is 83 points
The given parameters are:
- Addition of 20 points for rolling a 6
- Removal of 3 points for not rolling a 6
The probability of rolling a 6 in a fair die is 1/6.
The probability of not rolling a 6 in a fair die is 5/6.
So, the expected gain in each game is:
Take LCM
The number of games is 100.
So, the expected gain is:
Hence, the expected total gain is 83 points

It depends on how much the tickets cost. if they were each $5 they would make $8,595 from it.
If you were given any other info, (taxes, different prices for age groups, etc.) You would need to put that that into your equation.
