$21.00 because u take 29.99 x .30 and you get 8.99 the you subtract from 29.99 and get 21
Answer:
20 percent
Step-by-step explanation:
Total number of pieces in a puzzle = 500
No. of pieces in first container = 220
No. of pieces in second container = 180
Let no. of pieces in the third container be x.
We get,
![220+180+x=500](https://tex.z-dn.net/?f=220%2B180%2Bx%3D500)
On adding 220 and 180, we get
![400+x=500](https://tex.z-dn.net/?f=400%2Bx%3D500)
On transposing 400 to RHS, we get
![x=500-400=100](https://tex.z-dn.net/?f=x%3D500-400%3D100)
Percentage of pieces in the third container = (no. of pieces in third container/total no. of pieces in a puzzle) ![\times 100](https://tex.z-dn.net/?f=%5Ctimes%20100)
![=\frac{100}{500}\times 100=\frac{10000}{500}=20](https://tex.z-dn.net/?f=%3D%5Cfrac%7B100%7D%7B500%7D%5Ctimes%20100%3D%5Cfrac%7B10000%7D%7B500%7D%3D20)
Therefore, percentage of pieces in the third container = 20 percent
Answer:Relax the night before
Step-by-step explanation:
studies show the more calm you are during a test the higher chance you'll get a passing grade
Let the base of the pyramid be a square, then
s^2 + s^2 = 46.67^2
2s^2 = 2178.0889
s^2 = 2178.0889 / 2 = 1089.04445
s = 33
Volume = Area of the base x height
Area of the base = s^2 = 33^2 = 1089
Therefore, volume = 1089 x 24.93 = 27,148.77 cubic centimeter
