A: 100 cm³
This is because the others can be multiplied by something 3 times to get it, but A can not.
Answer:
1/2 (1 half)
Step-by-step explanation:
any number less than 4 is "1,2, and 3" and a standard die has 6 numbers. so if you have 3 out of 6 is equivalent to 1/2
Answer:
i) 4x
ii) Father's age = 3(x + 10)
Son's age = x + 10
iii) 4x + 10 = 3(x + 10)
iv) Present age of the son = x = 20
Present age of the father = 4x = 4(20)
= 80
Step-by-step explanation:
Present age of the son = x
Present age of the father = 4x
Age of the son in 10 years = x + 10
Age of the father in 10 years = 3(x + 10)
4x + 10 = 3(x + 10)
4x + 10 = 3x + 30
4x - 3x = 30 - 10
x = 20
Answer:
16 square feet
Step-by-step explanation:
First, let's find how long each side of the cube is.
The volume of a cube is found by this formula, where s is a side of the cube:
We can take the cube root of both sides:
Just flipping it:
We know our volume is 64 cubic feet. Let's put that into our equation as V:
The cubic root of 64 is 4, since 4 * 4 * 4 = 64
Thus, each side of our cube is 4 feet.
Now, the area of a side of our cube is found using this formula:
Since we know s, we can easily find the area A by squaring it:
Answer: 16 square feet
