Answer: 11.71 meters per second.
PLZ CORRECT ME IF I AM WRONG thxs and have a lovely day :)
Step-by-step explanation:
Answer:
8x + 7y = 30 ( one solution)
8x - 7y = 2
-8x + 7y = -2 ( infinitely many solutions )
8x - 7y = 2
8x - 7y = 2
-8x + 7y = 2 ( zero solutions )
4th root of a^5b²c^4=ac(4th root of ab²)
ac-7ac=-6ac,
so the result is -6ac(4th root of ab²)
Exact Form:
4/9
Decimal Form:
0.4
Using the combination formula, it is found that there are 792 ways to pick a team of 7.
The order in which the kids are chosen is not important, hence, the combination formula is used to solve this question.
