If they can be rounded to 70 to the nearest 10s. Then they are from 65 to 74.

Since they're distinct, so one can be 67 and one can be 69
5
you use the formula a^2+b^2=c^2
a=3, b=4
3*3=9 and 4*4=16
16+9=25
square root of 25 is 5.
5 is the answer
2400 divided by 10 is 240 and 240 x 3 = 720 so your answer would be 720 calories per day
I think the answer is D, 28*11=308 plus the 12*14 equals 476. The answer is D
