So 22/39 x 3/11 is 22x39 over 3/11

or 66/429.

Simplified would be 22/39.

The value of 22 / 39 of 3 / 11 on simplification is 6 / 39.

What is multiplication?

The fundamental concept of making the same number of additions repeatedly is represented by the action of multiplication. The results of multiplying two or more integers are known as the products, and the factors that are used in the multiplication are referred to as the factors.

Given:

22 / 39 of 3 / 11

As we know of means multiplication then,

22 / 39 × 3 / 11

A line passes through (2, 8) and (4, 12). Which equation best represents the line?
1. y = 1/2x + 6

2. y = 2x + 7

3. y = 2x + 4

4. y = 1/2x + 10

Answers

y=2x+4 because we’re moving up 2 units for every unit we move to the right, and if we plug 0 in for X we end up with the +4

I would say 3 (I am not completely positive, I am not that smart with graphs)

X: (2 + 4) / 2 Equals: 3
Y: (8 + 12) / 2 Equals: 10
Then multiple 3 by 2 get 6, add four, you get 10 which is equal to Y

A garden hose was left on in a yard and spilled 78 gallon every 23 minute. Find the average number of gallons spilled per minute.

Answers

Answer:

3.391 Gallons Per Minute

Step-by-step explanation:

78/23=3.391

Round 3.391 to 3.4

Answer:

≈3.39130434783 gallons per minute

Step-by-step explanation:

The information we get is a ratio, describing how many gallons of water will be wasted in 23 minutes, expressed as:

[tex]78 : 23[/tex] OR [tex]\frac{78}{23}[/tex]

We will use the fraction, the denominator is representing the time, which in this case, is 23 minutes. We want to have the denominator as 1 to find how much water will be spilled in one minute, to do this, we can divide both the numerator and denominator by 23:

[tex]\frac{78/23}{23/23} \\ =\frac{3.39130434783...}{1}[/tex]

And of course, if there's a need to round, go ahead.

And please do not waste water!

Answer:

8.06

Step-by-step explanation:

Decimals go in the order 10ths hundredths thousandths ten thousandths and so on. In rounding any decimal, one number gets added to the left if the number is 5 or over and the number is discarded if it is lower than 5.

for example if the number was 1.2345 5 would make 4 5 1.235 then 5woould make 3 4 1.24 but if you want to round to a smaller number the other numbers would not go up the numbers would just be discarded.

Stephanie ran four laps around the school track in 7 minutes and 30 seconds. How many seconds per lap is that?

Answers

112.5 seconds

First convert minutes to seconds so 7 x 60 + 30, that will get you the total seconds and should equal 450 secs. Divide that by 4: 450 / 4, equals 112.5 seconds

Answer:

112.5 seconds

Step-by-step explanation:

Stephanie ran four laps around the school track in 7 minutes and 30 seconds. How many seconds per lap is that?

You need to do convert 7 minutes in to seconds because you cannot do anything to this unless you convert it.

Remember

1 minute = 60 seconds.

So do 7 times 60.

7 × 60

Which is 420 seconds.

Now add the 30 seconds to that.

420 + 30.

Which is 450 seconds.

Now divided 450 by 4.

450 ÷ 4.

Which is 112.5 seconds per lap.

Find the percent markup

A store advertises a 35% markdown on the PlayStation 5 gaming console. It normally sells for $1,019. what is the final sale price?

Answers

the final sale price would be $662.35

ANSWER: $662.35

EXPLANATION:

We know the how much the PS5 cost and we know the markdown percentage. So we need to find 35% of 1,019 because we need to know how much to take away.

35% of 1,019 = 356.65

So now we take the original price and subtract 356.65 from 1.019.

When we do this we get $662.35

Thank you!Writing an Analytical Essay That Takes Advantage of HindsightRemember that hindsight is the advantage one has by writing about something after it has happened. In general, the more time has passed since an event, the greater advantage a writer has in writing about it. This is because as time passes, the effects of an event become more apparent.In this task, you will write an analytical essay that uses hindsight to determine cause-and-effect, showing how the Civil War and Reconstruction did or did not make significant progress toward creating a more equal society.Your analytical essay should be structured as follows:Introduction: Introduce the particular causes and effects you are analyzing and makes a clear and precise claim.Body Paragraphs: Provide information that supports your analysis of causes and effects. Reasons should be clearly stated and supported by well-sourced evidence. They should also be logically arranged and build upon one another. Relationships between claims and reasoning should be clear. Finally, include an explanation of how your viewpoint differs from that of someone immediately after the event took place because you have had the benefit of hindsight.Conclusion: Sum up your thoughts and analysis. Leave the reader with your most significant insight.Examine this sample analytical essay before writing your own.The Shifting Cause of the Civil WarPresident Lincoln's original stated goal in pursuing the Civil War was to keep the Union together. With the benefit of hindsight, however, it was inevitable that the focus of the war would shift to slavery. The South's claim that they were fighting for "states' rights" was, after all, a thinly veiled assertion that they had the right to own human beings. (South Carolina's Declaration of Succession, in fact, made no bones about this.)President Lincoln was fully aware of what motivated Succession. His delay in officially calling for slavery's end was almost certainly a political calculation. He knew that announcing his true intent from the beginning would lose him supporters in the border states, which maintained slavery while remaining in the Union. Waiting until the moment was rightand then ending slavery only in Confederate stateswas a shrewd decision on his part that contributed to eventual Union victory.The actions of the South after defeat highlight that the desire to keep enslaved persons had motivated Succession. Even though the Civil War technically settled the issue of slavery, the attitudes that created it remained widespread in Southern states for more than a century afterward. There was little support in the South for Reconstruction. In fact, they did everything they could to keep freed African Americans from true equality. Looking back, the strongest evidence supporting this fact was the passage of Black Codes, which meant to keep Black people in a state as close to slavery as possible. Those continued efforts to oppress African Americans led to the federal government's passage of the Thirteenth, Fourteenth, and Fifteenth Amendments, which were not actually ratified by every Southern state until the twentieth century.In hindsight, despite both the Confederacy's and Lincoln's initial assertions, it was inevitable that the Civil War would boil down to an openly acknowledged battle over abolition.Part A: Conduct Research and Document Sources and EvidenceResearch this question: Using hindsight to determine cause-and-effect, what evidence indicates that the Civil War and Reconstruction did or did not make significant progress toward creating a more equal society?
