Answer:

It'll take a bucket loads of $7 * 10^{20}$ to empty world's ocean

Step-by-step explanation:

Given

$World\ Ocean: 1.4 * 10^9 km^3$

$Bucket: 20,000 cm^3$

$1 km^3 = 10^{15} cm^3$

To get the number of bucket loads, we simply divide the size of the ocean by the size of the bucket;

$Number = \frac{Ocean\ Size}{Bucket\ Size}$

$Number = \frac{1.4 * 10^9 km^3}{20,000cm^3}$

Expand the numerator

$Number = \frac{1.4 * 10^9 * 1km^3}{20,000cm^3}$

Recall that $1 km^3 = 10^{15} cm^3$

So, the expression becomes

$Number = \frac{1.4 * 10^9 * 10^{15} cm^3}{20,000cm^3}$

Simplify the numerator using laws of indices

$Number = \frac{1.4 * 10^{9+15} cm^3}{20,000cm^3}$

$Number = \frac{1.4 * 10^{25} cm^3}{20,000cm^3}$

Expand the denominator

$Number = \frac{1.4 * 10^{25} cm^3}{2 * 10,000cm^3}$

$Number = \frac{1.4 * 10^{25} cm^3}{2 * 10^4\ cm^3}$

Split fraction

$Number = \frac{1.4}{2} * \frac{10^{25} cm^3}{10^4\ cm^3}$

$Number = 0.7 * \frac{10^{25}}{10^4\ }$

Simplify fraction using laws of indices

$Number = 0.7 * 10^{25-4}$

$Number = 0.7 * 10^{21}$

$Number = 7 * 10^{20}$

Hence, it'll take a bucket loads of $7 * 10^{20}$ to empty world's ocean

Im struggling on this problem PLEASE show the WORK (-x+3)-(x-5)

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3

Answer:

Let's simplify step-by-step.

− x + 3 − ( x − 5 )

Distribute the Negative Sign:

= − x + 3 + − 1 ( x − 5 )

= − x + 3 + − 1x + ( − 1 ) ( − 5 )

= − x + 3 + − x + 5

Combine Like Terms:

= − x + 3 + − x + 5

= ( − x + − x ) + ( 3 + 5 )

= − 2x + 8

Answer:

= − 2x + 8
