There are nineteen students in each homeroom, and three people left over.

well, the last part will be with a calculator, but you can simply use the area in π terms.
Answer: So they want you to find out the perimeter of the area!(8a so 8 times 2 is 16 times 3 is 48! Same-thing with the next one expect you divide 6 and 6 which is 1 and then since it says BY you multiple by 5. wich will give you 5.
Step-by-step explanation: Honestly i kind of explained it already! GOOD LUCK!!!!
Answer:
8
Step-by-step explanation:
By taking the number "3" and plus together with the number 5
1. D 1,750 Convert
2. B $2.47 Multiply the two quantities
3. D 39 5/6 lbs Multiply Kids by kids and adults by adults
4. C 132 Supplementary angles equal 180 degrees, so 180 - 48 = 132
5. Lines BE and AOD are complementary because they add up to 90 degrees or form an L.
6. 4 because 8 divided by 1/2 = 4
Try completing the rest by yourself!!!
