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
she can use all of the flowers. she cut down 9 and bought 18.
Answer:
like real numbers, the arithmetic operations, such as addition, subtraction, multiplication and division are applicable to the rational numbers
<u>Answer:</u>
- The length of the hypotenuse is 36 miles.
<u>Step-by-step explanation:</u>
<em>We can solve for 'a' using Pythagoras theorem. Let's solve it.</em>
- 39² = a² + 15²
- => 1521 = a² + 225
- => a² = 1296
- => a = 36
Hence, the length of the hypotenuse is 36 miles.
Hoped this helped.
