Answer:
36
Step-by-step explanation:
make proportion giants to elves
120/144 = 90/x cross multiply
120x =144*90
120x =12960 divide by 120
x = 108
so if there are 90 giants in the theater there are 108 elves also
considering that total 144 elves can be in the theater subtract 144 and 108 so 36 more elves can be admitted
Answer:

Ok, so the most she can carry is 4 books. and they weigh 1 - 3.5 lbs. so you take 1 times 4. and thats well 4. then you do 3.5 times 4. thats 14 so your range would be 4 -14 lbs
Total seats: 52 x 7 + 8 x 12 = 364 + 96 = 460
Total cost for total seats = 460 x 23 = 10,580
Cost for buses: 150 x 7 + 80 x 8 = 1050 + 640 = 1690
Total cost = 10,580 + 1,690 = $12,270
The value of 5.7 x 10⁸ is 570,000,000 CHOICE C.
The value of 8⁴ is 8 * 8 * 8 * 8 = 4,096 CHOICE C.
Prime factorization of 1,260
1260 ÷ 2 = 630
630 ÷ 2 = 315
315 ÷ 3 = 105
105 ÷ 3 = 35
35 ÷ 5 = 7
2 x 2 x 3 x 3 x 5 x 7 CHOICE D.
Composite numbers are numbers that have more factors other than 1 and itself.
91 / 1 = 91
91 / 7 = 13 CHOICE C. 91 is a composite number.
