Ronald ran 6 laps in 12 minutes. Which ratio can be used to find the number of laps that Ronald ran in 1 minute?

Sergio039 [100]

Answer:

0.5:1

Step-by-step explanation:

laps:minutes

So we can find how much Ronald runs in 2 minutes, by dividing 6:12 (or 6/12) by 6. This will give you 1:2 (One lap = 2 minutes).

But you're looking for 1 minute, so with 1:2, you have to divide them by 1/2, so it will be 0.5:1.

To solve this equation we must first plug in 5 for x.

$\frac{1}{3}$ (5 - 4x)
↓
$\frac{1}{3}$ (5 - 4 · 5)

The next step would be to multiply 4 by 5 to get rid of the parenthesis within our main parenthesis.

$\frac{1}{3}$ (5 - 4 · 5)

$\frac{1}{3}$ (5 - 20)

The next step would be to subtract both of the numbers within the parenthesis.

$\frac{1}{3}$ (-15)

Now we must multiply.

- $\frac{1}{3}$ · 15 = - $\frac{1×15}{3}$

- $\frac{15}{3}$

Now we simplify our answer to get our final answer.

What's the probability you roll the same number twice on a regular dice?

jekas [21]

1/6 because the first number that you roll doesn't matter so it depends on the 2nd roll, in which the probability of rolling a specific number is 1/6
