10 the second power is 10². 10²=10*10=100. 100*18.72=1,872. Hoped I helped. :)
Answer:
f(n+1) = 13
Step-by-step explanation:
- We know that f(1) = 15
- So we can substitute this for f(n)-3
- With this:
- f(n+1) = f(1) -3
- f(n+1) = 15-2
- f(n+1) = 13
Answer:
C
Step-by-step explanation:
So what you gotta do is count the lines. You don't count the one with one on it, but you count all the way through to 2. That gets you eight, so each line is 1/8. 1-2 in 1/8 intervals. 1 1/4 multiply 2 on the numerator and denominator gets 1 2/8, 1 1/2 multiply 4 on the numerator and denominator gets you 1 4/8. Counting the lines, each of those matches up. The first interval is 1 1/8.
2 have 10
others have 20
5 present total
2 have 10 pounds
5-2=3
3 have 20 pounds
total weight=2 times 10+3 times 20=20+60=80
80 bounds
1pound=16oz
80 times 1pound=16oz times 80
80 pounds=1280oz
answe ris 1280 oz
