The expression equivalent to ∛162 is ∛6 × ∛27

<h3>What is the cube root of a number?</h3>

The cube root of a number is a number a such that when another number, b multiplies itself 3 times, we get a.

So,

  • a = b × b × b = b³and
  • b = ∛a

<h3>What is a perfect cube?</h3>

A perfect cube is a number such that its cube root which is an integer or whole number.

<h3>How to find ∛162.</h3>

Since we have ∛162.

Since 162 is not a perfect cube, to find its cube root, we have

∛162 =  ∛(54 × 3)

= ∛(18 × 3 × 3)

= ∛(2 × 9 × 3 × 3)

= ∛(2 × 3 × 3 × 3 × 3)

= ∛(6 × 27)

= ∛6 × ∛27

So, the expression equivalent to ∛162 is ∛6 × ∛27

In one game, the ratio of three-point baskets to three-point tries for one team was 3:8. If the team scored 27 points from three
nasty-shy [4]

Since we’ve been given a ratio, 3:8, we can convert that into a fraction and form an equation from it:

\frac{3}{8} = \frac{27/3}{?}

The reason the numerator on the second fraction is 27/3 is because the team scored 27 points, not 27 baskets.

Simplify (Also replace the ? with an unknown variable):

\frac{3}{8} = \frac{9}{n}

Cross multiply:

3*n = 9*8

Simplify:

3n = 72

Divide both sides by 3:

n = 24

The team had 33 three point tries, 9 successes, and 24 fails.

Find the distance between points A = (2, 0) and
allochka39001 [22]

Answer:

  9.2

Step-by-step explanation:

You want the distance between A(2, 0) and B(0, 9).

<h3>Distance</h3>

The distance formula is based on the Pythagorean theorem. It tells you the distance between (x1, y1) and (x2, y2) is ...

  d = √((x2 -x1)² +(y2 -y1)²)

For the given points, this becomes ...

  d = √((0 -2)² +(9 -0)²) = √(4+81) = √85

  d ≈ 9.2

The distance between A and B is about 9.2 units.
