Question 12(Multiple Choice Worth 1 points)

rusak2 [61]

Answer:

$\frac1{25}$

Step-by-step explanation:

Hello!

Let's use a couple of exponent rules:

$\frac{a^x}{a^b} = a^{x - b}$
$a^{-x} = \frac{1}{a^x}$

Let's utilize the first rule and simplify the fraction.

<h3>Simplify</h3>

$\frac{5^4}{5^6}$
$5^{4 - 6}$
$5^{-2}$

Now, we can utilize the second exponent rule, as we have a base to the power of a negative number.

<h3>Simplify</h3>

$5^{-2}$
$\frac1{5^2}$
$\frac1{25}$

The answer is option 1, $\frac{1}{25}$ .

It takes 40 min for a bus to cover 36 miles. A car travels 1.4 times faster. When will they meet if they started 36 miles apart

sveticcg [70]

40 min = 36 miles

1 min = 36 ÷ 40 = 0.9 mile

1 min = 0.9 x 1.4 = 1.26 miles

<u>Total distance covered by both vehicles in 1 min: </u>

1.26 + 0.9 = 2.16 miles

<u>Time needed for both of them to cover 36km:</u>

36 ÷ 2.16 = 16 2/3 min

Answer: They will meet 16 2/3 mins after they have started.
