A pipe is draining water from a tank. The table below shows the time in minutes and the number of gallons remaining in the tank. 5 mins drained 300 gallons, 10 mins drained 260 gallons, 15 mins drained 220 gallons, 20 mins drained 180 gallons, and 25 mins drained 140 gallons. Based off the pattern/rate, how much water would be drained in a half an hour?

Answers

Answer: 3,600 gallons in an hour and a half

Step-by-step explanation:

Because every 5 minutes it drained 40 gallons so you’d have to do 40 times 90 because there is 90 minutes in a half an hour and that gives u 3,600 gallons

3,600 gallon in a hour

At a construction job for a theater, there are 30 painters. Of these painters, 24 of them are painting the interior of the theater. What percent of these painters are painting the interior?

Answers

Answer:

80 percent of the workers are painting the interior

Step-by-step explanation:

24 of 30 is 80 percent

Answer:

80%

Step-by-step explanation:

Let's do this

So they are asking "What percent of these painters are painting the interior?"

So use this formula-

Second number mentioned/First number mentioned*100

As it says "What percent of these painters are painting the interior?" , the interior number is the second number and the total painters is the first number mentioned.

So let's put the values-

24/30*100=80%

The answer is 80%.

Which is the simplified form of the following expression? 7x - 9y + 4x^2 - 2x + 12y


A. 13x + 3y

B. 11x + 21y

C. 4x2 + 5x + 3y

D. 4x2 + 9x + 21y

Answers

i think its c because 7x-2x is 5x, -9y + 12y is 3y, and 4x^2 stays the same

Rearrange it so the x is on the left and y is on the right starting with the highest x value which is x^2

4x^2 + 7x - 2x - 9y + 12y
= 4x^2 + 5x + 3y

There the answers is C.

It is the 4th crusadeWill give brainliest!In 1198, Pope Innocent III called for a new Crusade, more out of a desire to elevate the papacy than in response to events in the Holy Land. This Crusade failed to rouse any monarchs. Led largely by French knights, the crusaders set out for the Holy Land in 1202 only to be distracted by Venetian lords who convinced them to capture the wealth and splendor of Eastern Orthodox Constantinople instead. So, rather than retake the Holy Land from Muslim rule, the Fourth Crusade sacked the capital of the Byzantine Empire, a Christian city. However, crusaders control of Constantinople lasted less than a century. The major accomplishment of this Crusade proved to be weakening the Byzantines enough that they could no longer hold off Muslim expansion. 24% of what number is 16.08 Evaluate the expression 8n for n = 1 5/12 (4.076 x 10^4) + (3.2 x 10^4) Which group supported farming as the basis for the economy?FederalistsAnti-federalists Rocks that do not allow water to pass through them are said to be impermeable.
