The volume of a cube is 1000 cubic inches. What is the edge length of the cube?

1 answer:

7 0

We know that the formula for cube volume is a³ and that we're looking for a in this specific case, so we can write it down as a simple equation:

a³ = 1000 / ∛ (both sides)
a = ∛1000
<u>a = 10</u>

Doublecheck:

10³ = 10 * 10 * 10 = 1000, so it's correct ;)

Five years from now, the sum of the ages of a women and her daughter will be 40 years. The difference in their present age is 24

Tomtit [17]

Answer:

Daughter age = 3 years

Step-by-step explanation:

Let x be the age of the women and y be the age of the daughter.

Given:

After five year the sum of the women and daughter age = 40

$(x+5)+(y+5)=40$

At present the sum of the women and daughter age

$x+5+y+5=40$

$x+y+10=40$

$x+y=40-10$

$x+y=30$ --------------(1)

So the sum of the present age is $x+y=30$

The difference in their present age is 24 years.

$x-y=24$

$x=24+y$

Now we substitute x value in equation 1.

$(24+y)+y=30$

$24+2y=30$

$2y=30-24$

$2y=6$

$y=\frac{6}{2}$

$y=3\ years$

Therefore, the daughter age is 3 years.
