Step-by-step explanation:
The two given boxes for reference are presented below.
Since we know the dimensions of the first container, we can calculate its volume.
The first container held 192 skittles. Using that fact, now that we know the volume of the first box, we can calculate the volume of a single skittle.
The second container held 258 skittles.
The volume of the second box is:
Using this facts, the volume of a single skittle would be
Therefore, the volume of single skittle is around to 0.42 cm³.
A skittle jar is a cylinder. Its volume is calculated by the formula
,
where is the radius and
is the height. From the given data, we have
and
. Hence, the volume of the jar is
Now, we can determine the number of skittles in the jar. Let be the number of skittles in the jar. Then,
Hi there!
We can split into factors using the "guess and check" method.
Factors are in the format of:
(ax + b)(cx + d), where in this instance:
a · c = 2
bc + da = 5
b · d = 3
Thus, we get:
(2x + 3)(x + 1)
