Answer: Independent quantity : number of jelly beans in the jar guessed.
Dependent quantity : number of the jelly beans each person was off by.
Step-by-step explanation:
- Independent quantity : A quantity that the experimenter can change or control.
- Dependent quantity : A quantity that depends on each independent quantity.
In the given scenario, there are two quantities introduced:
- number of jelly beans in the jar guessed.
- number of the jelly beans each person was off by.
Since, "number of the jelly beans each person was off by." depends on "number of jelly beans in the jar guessed.".
So,
Independent quantity : number of jelly beans in the jar guessed.
Dependent quantity : number of the jelly beans each person was off by.
Answer:
4.5 km
Step-by-step explanation:
3km times 1 = 3 and then 3km times .5 = 1.5
3+1.5= 4.5
228 because no hours have passed
Answer:
8/9
Step-by-step explanation:
The total surface are of cylinder comprises of the lateral or curved surface area + the area of the flat surface on the top and bottom
The lateral surface area is calculated this way
curved area of the face × height
Here it is a circle and hence its circumference is 2πr
Hence the formula become
2πr × h = 2πrh
So 2πrh is the part that represents the curved area of the cylinder
(Additional info: The area of the faces is given by πr² for one side, since a cylinder has 2 faces
we have πr²+πr²=2πr²
Hence the total surface area is 2πrh +2πr²)
