There is 3 variable, in this case, painters, walls and time(minutes). You need to find how many painters needed and provided information on the walls and time(minutes).
Increasing walls will cause more painter needed. It was reversed in time which was increased time will cause less painter needed.
In this case, you need to divide the variable walls with time since it reversed so: 27wall/9 minutes
It equal to : 3 walls/minute
Information provided is:
3 painters= 3 walls/3 minutes
Equal to : 3 paintes= 1 wall/minute
To make it 3 walls/minute, the painter needed will be:
(3 walls/minute) / (1 wall/minute) x 3 painters= 9 painters
Answer: 9 painters
Answer:
3rd Answer =Option A is the Correct Answer
Step-by-step explanation:
Answer:
Option B ⇒ Area of base of each pyramid :
Option A ⇒ Volume of pyramid :
cm3
Step-by-step explanation:
One side of tile consists of 4 pyramids and since length of whole tile is x,
So, the base length of each pyramid = ![\frac{x}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B4%7D)
⇒ Area of base of each pyramid = side²
⇒ Area =
![(\frac{x}{4})^2 in^2](https://tex.z-dn.net/?f=%28%5Cfrac%7Bx%7D%7B4%7D%29%5E2%20in%5E2)
Volume of square based pyramid :
![=(Area of base )\cdot \frac{h}{3}\\=\frac{x^2}{3} cm^3](https://tex.z-dn.net/?f=%3D%28Area%20of%20base%20%29%5Ccdot%20%5Cfrac%7Bh%7D%7B3%7D%5C%5C%3D%5Cfrac%7Bx%5E2%7D%7B3%7D%20cm%5E3)
For 1. The correct Option is B
For 2. The correct option is A
I could be wrong, but I think it could be D, 18.5.
