When Luis begins painting, he realizes it takes him 45 seconds to complete 1 square foot. The room he is painting has 272 square
zepelin [54]

It will take Luis 12240 seconds to complete the project.

12240 seconds are 204 minutes when converted.

Step-by-step explanation:

Given,

Time taken to paint 1 square foot = 45 seconds

Time taken for 272 square feet = 45*272

Time taken for 272 square feet = 12240 seconds

We know that;

60 seconds = 1 minute

Therefore;

We will divide the total seconds by 60 to convert them into minutes.

12240 seconds = \frac{12240}{60} = 204\ minutes

It will take Luis 12240 seconds to complete the project.

12240 seconds are 204 minutes when converted.

levacccp [35]

Answer:

9

Step-by-step explanation:

Take the sides in proportion.

⇒ \frac{AE}{AD} =\frac{AB}{AC}

⇒ \frac{12}{12+8} =\frac{x}{15}

⇒ \frac{12}{20} =\frac{x}{15}

⇒ \frac{3}{5} =\frac{x}{15}

⇒ 3 = \frac{x}{3}

⇒ x = 3 × 3

⇒ x = 9
