45) 1/625
46 )1/729
47) 1/49
48) 1/64

Answer 2

#49 is 66 choices because 12*11=132 divided by 2

Answer 3

I don't understand the last two questions at all

Answer 4

You are right for numbers 45 to 48. For 50, let m represent time spent on math and e represent time spent on English. m = 35, and the total time is 90.

35 + e < or = 90

You see here, the time spent on math, 35 minutes, added to the time spent on English, e, can be no more than 90. Your answer is above.

For 51, the answer is 46h + 74 = 304. 46 feet per hour times the number of hours, h, plus the initial height of 74 equals the total height of 304. Now let's solve this.

46h + 74 = 304
46h = 230
h = 5

So it will take them 5 hours to climb to 304 feet.
