Using the similar triangles, which equation could be used to find the slope of line AB?
NARA [144]

Answer:

A) slope = p/q

Step-by-step explanation:

Slope of any given can be found using the formula, \frac{rise}{run} = \frac{y_2 - y_1}{x_2 - x_1}.

In this case, using similar triangles, the rise over the run of any of the given similar triangles will give us the slope of line AB.

This means, slope of line AB would be:

\frac{rise}{run} = \frac{m}{n} = \frac{p}{q}.

✅Therefore, slope of line AB = p/q

The world's oceans hold roughly 1.4 x 109 cubic kilometers of water. A typical bucket holds roughly 20,000 cubic centimeters of
MissTica

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
