We are given a six-sided cube. To determine the surface area and the volume of the cube, we need to know the area of one side:
All sides of the cube are squares with side, s. The area of one square is
A = s^2
The surface area of a cube is the sum of all areas of the sides. So
SA = 6 sides * s^2
SA = 6s^2
The volume of the cube is
V = s^3
The volume of the cube represents the total solid area of the cube which includes the space inside the solid.
Four oranges cost 90 cents, an orange costs 90/4 cents, which is around 22.5 cents. Multiply this by 36 to get the cost of 3 dozen oranges, so 22.5 times 36 is 810, 810 cents, or 8.10 dollars.
Answer:
20 lbs
Step-by-step explanation:
2/5ths of the food would be 20 pounds because:
2/5 * 50 = 20
2/10ths of the food would be 10 pounds because:
2/10 * 50 = 10
If we add those two together, we would get the total amount that the dog ate, which would be 30 pounds. SInce the dog ate 30 pounds of food out of the 50 pounds, there would be 20 pounds left in the bag at the end of two months:
50- ( 20+ 10) = 20
Answer: 
Step-by-step explanation:
For this exercise you need to remember:
1) The mulitplication of signs:
2) By definition, like terms contain the same variables with the same exponent.
Then knowing this, and given the equations:
and 
You must subtract the like terms, which means that you must subtract the numerical coefficients of each term.
Then, you get the result is:
Answer:
777 rice balls
Step-by-step explanation:
700700700 divided by 100100100 equals 7. 7 times 111 equals 777.
