Answer:
It will cost approximately $16.12 to varnish all the wooden planks.
Step-by-step explanation:
We are given the following in the question:
Number of rectangular planks = 12
Dimension of the rectangular wooden plank:
Length = 8 feet
Width = 3 feet
Area covered by I bottle of varnish = 125 Square feet
Cost of 1 bottle of varnish = 3.50 units
Area of 1 rectangular plot =
Total area to be covered by varnish =
Number of varnish bottles required =
Cost of varnishing =
Thus, it will cost approximately $16.12 to varnish all the wooden planks.
Answer choice 2 would be the correct one! If the sides were all curved they would be cylinders.
Answer:
Step-by-step explanation:
Volume = length * width * height
= (x + 1) *x *(3x + 5)
Multiply (x +1) and x
= (x*x + x*1) * (3x +5)
= ( x² + x) * (3x + 5)
= x²*(3x +5 ) + x(3x +5)
=x²*3x + x²*5 + x*3x + x*5
= 3x³ + 5x² + 3x² + 5x
= 3x³ + 8x² + 5x
Answer:
D. $512,000
Step-by-step explanation:
Well if the balance doubles every 5 years, then dividing 40 by 5 gives us the number of times the money will double, which is 8. We can then turn this into the equation . can be simplified to 256. Multiply that by 2000 and we get our answer, 512000. Hope this helps!
