Use tI 84 calculator .
go to y= and then plug the equation in the side then you will find the answer
Answer:
45
Step-by-step explanation:
The order in which the items are chosen is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
How many possible subsets of 2 items can be chosen from this lot?
Combinations of 2 from a set of 10. So
Step-by-step explanation:
it is a box or prism.
the volume is simply
length × width × height
in our case
8m × 6m × 5m = 240 m³
doubled dimensions means
16m × 12m × 10m = 1920 m³
the difference is
1920 - 240 = 1680 m³
we could have gotten the new volume also based on the original volume :
2×8m × 2×6m × 2×5m = 8m×6m×5m × 2×2×2 =
= the original volume (240 m³) × 8 = 1920 m³
