Answer:
The sum of their ages is 1 less than 3 times Rosa's age.
15 + 8 = 3(8) - 1
Step-by-step explanation:
Answer:
2520 ways
Step-by-step explanation:
We can solve this problem with 3 combinations:
First the teacher needs to give 3 fruit snacks to 10 students, so we have a combination of 10 choose 3: C(10,3) = 10! / (3! * 7!) = 120
Then, she needs to give 2 teddy grahams to 7 students (3 already got a snack), so a combination of 7 choose 2: C(7,2) = 7! / (2! * 5!) = 21
The, she gives the 5 granola bars to the other 5 students, so a combination of 5 choose 5: C(5,5) = 1.
Now we just need to multiply the combinations to find the result:
C(10,3) * C(7,2) * C(5,5) = 120 * 21 * 1 = 2520 ways
Heya!
We can use the extended version product rule to solve: log_p(abc) = log_p(a) + log_p(b) + log_p(c)
We can factor 60 using 2, 3, and 5.
60 = 2^2 * 3 * 5
Substitute these numbers into the rule.
log(2^2 * 3 * 5) = 2 log_p(2) + log_p(3) + log_p(5)
Using the values given in the question, we can substitute in the equation.
2 log_p(2) + log_p(3) + log_p(5) → 2(0.09) + 0.14 + 0.21
Simplify the equation.
2(0.09) + 0.14 + 0.21
0.18 + 0.14 + 0.21
0.53
Therefore, 
Best of Luck!
