When you cube or square a number it means to multiply a number by itself a certain amount of times. So when you square a number you multiply that same number together twice and when cubing a number you multiply that same number three times. In your case multiply 1/5 like this: 1/5 x 1/5 x 1/5

Perform the operation and reduce the answer fully. make sure to express the answer as a simplified fraction

Alik [6]

Answer:

$\frac{3}{5}$

Step-by-step explanation:

Given:

$\frac{4}{5} \div \frac{4}{3}$

Required:

Simplify

SOLUTION:

$\frac{4}{5} \div \frac{4}{3}$

Turn the division operation to multiplication, and flip the fraction by your right upside down

$\frac{4}{5} \times \frac{3}{4}$

4 cancels out 4

$\frac{1}{5} \times \frac{3}{1}$

$\frac{1 \times 3}{5 \times 1}$

$\frac{3}{5}$

Therefore, $\frac{4}{5} \div \frac{4}{3} = \frac{3}{5}$

A blue die and a red die are thrown. B is the event that the blue comes up with a 6. E is the event that both dice come up even.

iVinArrow [24]

Answer:

Size of |E n B| = 2

Size of |B| = 1

Step-by-step explanation:

<em>I'll assume both die are 6 sides</em>

Given

Blue die and Red Die

Required

Sizes of sets

- $|E\ n\ B|$

- $|B|$

The question stated the following;

B = Event that blue die comes up with 6

E = Event that both dice come even

So first; we'll list out the sample space of both events

$B = \{6\}$

$E = \{2,4,6\}$

Calculating the size of |E n B|

$|E n B| = \{2,4,6\}\ n\ \{6\}$

$|E n B| = \{2,4,6\}$

<em>The size = 3 because it contains 3 possible outcomes</em>

Calculating the size of |B|

$B = \{6\}$

<em>The size = 1 because it contains 1 possible outcome</em>

In 15 minutes, Jada would have covered about 2.5 miles, while the cousin would have covered 0.625 miles.

<h3>What is speed?</h3>

Speed is the ratio of distance to time.

For Jada:

Speed = 2 miles / 12 minutes = 0.167 miles per minute

For Jada cousin:

Speed = 1 mile / 24 min = 0.0417 miles per minute.

Hence, in 15 minutes:

Jada distance = 15 min * 0.167 miles per minute = 2.5 miles

Jada cousin distance = 15 min * 0.167 miles per minute = 0.625 miles

In 15 minutes, Jada would have covered about 2.5 miles, while the cousin would have covered 0.625 miles.
