Sally can paint the office by herself in 5 hours. Lucy can do the same job in 4 hours. How long will it take them to do it work

Zepler [3.9K]

Answer:

2.22 hours

Explanation:

If Sally can paint the office by herself in 5 hours, we can say that in one hour she paints 1/5 of the office.

On the other hand, Lucy paints the office in 4 hours, which means that, in 1 hour she paints 1/4 of the office.

Therefore, to know how much they would paint per hour working together, we are going to sum up the fractions they paint per hour:

$\frac{1}{5} +\frac{1}{4}=\frac{4+5}{20} =\frac{9}{20}$

Therefore, working together they will paint $\frac{9}{20}$ $=0.45$ of the office in one hour.

Now we can establish a rule of three: if they paint 0.45 of the office in 1 hour, how long (x) will it take them to paint 1.0 of the office?

$1- 0.45\\x-1$

And therefore $x = \frac{1}{0.45}=2.22$

Therefore, it will take them 2.22 hours to paint the office working together.

Answer/Explanation:

Christianity has its roots in Judaism.

Christians believe in Jesus, a carpenter who began to travel and teach new ideas about Judaism around 30 CE.

He believed that the old laws of Judaism should be replaced by a simple system based on love and kindness.

Christians believe that Jesus was the Messiah, or savior.

Jesus performed miracles, and after people saw the results, they became followers.

He laid his hands on people and could heal them.

Jesus used parables (stories that teach lessons) to link his teachings to people’s everyday lives.

Jesus soon gained a large following.

Jesus was not popular with Jewish leaders.

They did not want him to threaten their power and had the Romans arrest him.

Jesus was crucified at the age of 33.

Christians believe that Jesus rose from the dead and went to heaven three days later.

They saw the Resurrection as a sign that Jesus was the Messiah.

EQ: What role should the national and/or state government take in education?

vampirchik [111]

Answer:

The federal government plays a role in evaluating each school district by administering the National Assessment of Educational Progress (NEAP), also known as the Nation's Report Card. Finally, federal agencies such as the National Science Foundation and the Department of Education publish recommended teaching strategies and materials.

The states are the entities primarily responsible for the maintenance and operation of public schools. The states are also heavily involved in the establishment, selection, and regulation of curriculum, teaching methods, and instructional materials in their schools. Consequently, each state has different standards and policies which may impact the quality of education offered.
