You could do 3 x 3 x 5 x 5 for perimeter, so the area is 3 x 5.
The answer therefore, is 15 ft²
Answer: the height of the melted candies in the pot is 12.2 mm
Step-by-step explanation:
The formula for determining the volume of a square base pyramid is expressed as
Volume = area of base × height
Area of the square base = 12² = 144 mm²
Volume of each pyramid = 15 × 144 = 2160 mm³
The volume of 100 pyramid shaped chocolate candies is
2160 × 100 = 216000 mm³
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
Since the pyramids was melted in the cylindrical pot whose radius is 75 mm, it means that
216000 = 3.14 × 75² × h
17662.5h = 216000
h = 216000/17662.5
h = 12.2 mm
The value of x is 4
to show your work:
8x + 7 = 6x + 15
- 7 - 7
8x = 6x + 8
-6x -6x
2x=8
divid by 2 and it’s x = 4 :)
