Alice cycles to Carla's house at 12 mph and returns by car at 36 mph. If the round trip takes 1 hour, how far away from Carla do

Eduardwww [97]

Answer:

Alice lives <u>9 miles</u> far away from Carla.

Step-by-step explanation:

Given:

Alice cycles to Carla's house at 12 mph and returns by car at 36 mph.

If the round trip takes 1 hour.

Now, to find the distance from Carla to Alice house.

So, let the distance between the houses of Carla and Alice be $x$ .

Now, we solve by using the formula:

Distance/speed = time

Alice cycles to Carla house = $\frac{x}{12}$

And return by car = $\frac{x}{36}$

Time taken for round trip = 1 hour.

Adding both the distance to get the value of x:

$\frac{x}{12}+\frac{x}{36}=1$

$=\frac{3x+x}{36}=1$

$=\frac{4x}{36}=1$

<em>Dividing both sides by 4 we get:</em>

$x=9$

Therefore, Alice lives 9 miles far away from Carla.

What expression is equivalent to

kaheart [24]

Answer:

Option (2)

Step-by-step explanation:

Given expression is $\sqrt[3]{64a^6b^7c^9}$

By simplifying this expression,

$\sqrt[3]{64a^6b^7c^9}=\sqrt[3]{(4)^3(a^2)^3(b^2)^3(b)(c^3)^3}$

$=(4a^2b^2c^3)\sqrt[3]{b}$

Option (1)

$2abc^2\sqrt[3]{4a^2b^3c}$ = $2ab^2c^2\sqrt[3]{a^2c}$

Option (2)

$4a^2b^2c^3(\sqrt[3]{b})$ [Fully simplified form]

Option (3)

$8a^3b^3c^4(\sqrt[3]{bc} )$ [Fully simplified form]

Option (4)

$8a^2b^2c^3(\sqrt[3]{b})$

Expression given in Option (2) is equivalent to the given expression.

Option (2) will be the answer.
