First, we need to know the smallest two digit prime number. It can't start with one, since one is not prime, so it must start with two (or be in the twenties.) 20 is divisible by 2, 4, 5, and 10, 21 is divisible by 7 and 3, 22 is divisible by 2 and 11, so the smallest prime number is 23.
Now we need the largest two-digit prime number. It cannot start with nine or eight, since both are composite, so it must start with seven (be in the seventies.) 79 is the largest integer in the seventies and also happens to be prime, so there's our largest two digit prime number.
now we just need to add them for the sum:
23+79=102
hope I helped, and let me know if you have any questions :D
Answer: 26 gallons.
390÷15
15 can go into 39 only 2 times.
39-30 is 9
15 can go into 90 only 6 times.
90-90 is 0.
Answer:
19
Step-by-step explanation:
10[4 times 10 divided by (6^2-4^2) +1]
First you would multiply 6 x 6 = 36
10[4 times 10 divided by (36-4^2) +1]
Second you would multiply 4 x 4 = 16
10[4 times 10 divided by (36-16) +1]
Third you would subtract 36 - 16 = 20
10[4 times 10 divided by 20 +1]
Fourth you would add 20 + 1 = 21
10[4 times 10 divided by 21]
Fifth you would multiply 4 x 10 = 40
10[40 divided by 21]
Sixth you would divide 40 divided by 21 = 1.90
10[1.90]
Seventh you would multiply 10 x 1.90 = 19
Your answer would be 19.
Hope this helps. I am sorry if you get this wrong.

Its a i just took the test
Step-by-step explanation:
Answer:
Step-by-step explanation:
Number of hurricanes in year 2008 = 8
Number of hurricanes in year 2009 = 3
Decrease in number of hurricanes = 8 - 3 = 5
Percent of decrease in number of hurricanes = 
= 62.5%
Number of hurricanes in year 2010 = 12
Number of hurricanes in year 2011 = 7
Decrease in number of hurricanes = 12 - 7 = 5
Percentage decrease in number of hurricanes = 
= 41.7%
Decrease in numbers of hurricanes in year 2010 - 11 was same as in year 2010 - 11.
Percentage decrease in hurricanes were more in year 2008 - 09 than percentage decrease in year 2010 - 11.
