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.

Please need help fast<br> Instructions: Match the following data with the correct histogram.

Furkat [3]

The histogram that correctly shows the data in the table is the histogram number four.

<h3>What is a histogram?</h3>

This a type of graph that allows people to visually represent data by using bars and gathering the data they have in different categories.

<h3>How should the data in the table be represented?</h3>

This data can be represented using ranges of temperature and the number o elements or substances in these ranges.

0-500°C = 5 elements
500 - 1000°C = 1 element
1000-1500°C = 1 element
1500-2000°C = 1 element
2000-2500°C= 2 elements
2500-3000°C= 2 elements
3000-3500°C= 2 elements
3500-4000°C= 1 element

This data matches the fourth graph

What should A and B equal?<br><br> marking brainliest for correct answer!!

Rzqust [24]

Answer:

$a = 5$

$b = - 3$

Step-by-step explanation:

Let set up the equation

${2}^{ - 3} \times {a}^{ - 3} = {10}^{b}$

First, let solve for a.

Since our product base is 10 and one of our factor base is 2. We need to find a number to multiply 2 by to get 10.

$2 \times a = 10$

$a = \frac{10}{2}$

$a = 5$

Let replace a in the equation,

${2}^{ - 3} \times {5}^{ - 3} = {10}^{b}$

Using the rule that if two exponet have the same power but different bases, we multiply the bases and keep the same power.

We already multiplied the bases.

The power stay the same so b=-3

Perform the indicated operation.(3/a+2) + (4/a-5)

kipiarov [429]

Answer:

$\frac{7(a-1)}{(a+2)(a-5)}$

Step-by-step explanation:

To solve this operation we need to find the common multiple of both denominators and solve for a.

$\frac{3}{a+2} + \frac{4}{a-5} =\frac{3(a-5)+4(a+2)}{(a+2)(a-5)} =\frac{3a-15+4a+8}{(a+2)(a-5)} =\frac{7a-7}{(a+2)(a-5)} =\frac{7(a-1)}{(a+2)(a-5)}$

Thus, the solution is 7(a -1) / (a+2)(a-5)
