Answer:

15 kilometres

Step-by-step explanation:

Based on the wording of your question, I am assuming you already know that Paul ran 250 metres every 1 minute, and that the ratio is 250:1. To get the second part of the answer, convert metres to kilometres. 0.001*250= 0.25. Paul ran 0.25 kilometres per minute. The ratio of kilometres per minute is 0.25:1. Next, convert minutes to hours. Multiply the entire ratio by 60, as there are 60 minutes in an hour. The ratio of kilometeres per minute is 15:60, and the ratio of kilometres per hour is 15:1, meaning Paul ran 15 kilometres in one hour.

Answer:

D. log(9)

Step-by-step explanation:

$log(9x^{5})+5log(\frac{1}{x})$

Remember: $A log (x) = log(x^{A})$

$log(9x^{5})+log((\frac{1}{x})^{5})$

Remember: $log_{a} (x)+log_{a}(y)=log_{a}(xy)$

$log(9(\frac{1}{x})^{5}x^{5})$

Simplify...

$log(9)$

Hope this helps! If you need steps for simplifying, just ask! :]

Mr jb has a rectangular lot that measure 550 meters by 0.75 km.What is the area of the land in square meter. He is selling the w

Art [367]

Answer:

The area in square meter is 412,500 square meters

the price per square meter is 500 pesos per square meter

Step-by-step explanation:

Firstly, let us get the measure of the dimensions in meters

Mathematically, 1000 m = 1 km

Thus;

0.75 km = 0.75 * 1000 = 750 m

The area of a rectangle is the product of its side lengths

mathematically, we have this as;

550 * 750 = 412,500 square meters

To get the price per square meter, we have to divide the price of the whole plot by the area

So we have ;

(206,250,000) pesos / 412,500 square meters

= 500 pesos per square meter
