The answer is 6 square inches
Answer:
This is a perfect cube.
The side length is 4.
Taking the cube root of the volume will determine the side length.
Step-by-step explanation:
We are told that:
A cube has volume 64 centimeters cubed.
The formula for the volume of a cube = s³
Where s = side length
Hence
64 cm³ = s³
We can find s by finding the cube root of both sides
Hence,
cube root(64) = cube root(s³)
s = 4 cm
Note that 64 is a perfect cube because 4 × 4 × 4 = 4³ = 64 cm³
Therefore, it can be concluded of the cube that:
This is a perfect cube.
The side length is 4.
Taking the cube root of the volume will determine the side length.
Answer:

0.16
Step-by-step explanation:
According to the question the mathematical model should be

Differentiating with respect to time we get

So, the rate of change of brightness after t days is 
After 1 day means 

The rate of increase after one day is 0.16.
Answer:
2/15 pound of dog food
Step-by-step explanation:
John has 4/5 of a pound of dog food left to share equally among 6 dogs in his pet shop. How many pounds of food can he give to each dog?
From the above question, we can deduce that:
6 dogs = 4/5 pound of dog food
1 dog = x pound of dog food
Cross Multiply
6 dogs × x pound = 1 dog × 4/5 pound of dog food
x pound = 1 dog × 4/5 pound of dog food/6 dogs
x pounds = 4/5 ÷ 6
x pounds= 4/5 × 1/6
x pounds = 4/30
x pounds = 2/15 pound of dog food
Therefore,if the dog food is shared equally, he can give each dog 2/15 pound of dog food.
