Answer:
The classroom has 14 bottles of glue.
Step-by-step explanation:
35÷5=7
7×2=14 (14 being two fifths the amount of glue sticks since the ratio is 5:2)
14
ratio of glue sticks to glue bottles is 5:2 so number of glue bottles = 35×2=14 or you can think that for every 5 glue sticks, you will have 2 glue bottles. Since 35means 5×7, then the number of glue sticks will be 2×7 which is 14
0.1*√20000 = 14.1421356237
-0.05*√28800 = -8.48528137424
the answer is definition of angle bisector
