A school assembly had 600 students in attendance, and 35% of them were first-graders. How many first-graders were at the assembly?

can u also list the formula on how to do this while ur at it pls and ty

Answers

Answer:

210 Were First Graders

Step-by-step explanation:

35 percent of 600 is the same as 35 per hundred of 600. We can therefore make the following equation:

35/100 = X/600

To solve the equation above for X, you first switch the sides to get the X on the left side, then you multiply each side by 600, and then finally divide the numerator by the denominator on the right side to get the answer. Here is the work to illustrate:

35/100 = X/600

X/600 = 35/100

X*600/600 = 35*600/100

X = 21000/100

X = 210

The work above shows the long way to explain how to calculate 35 percent of 600 in order to give you a foundation and better understanding of how to calculate percentage. In the future, you could use this simplified formula:

(Y * P)/100

In our problem "What is 35 percent of 600?", Y is 600 and P is 35:

(600 * 35)/100 = 210

And once again you see that the answer is 210.

Answer:

210 kids

Step-by-step explanation:

So the formula is basically part over whole is equal to x/100%

So for here it would be x/600 = 35/100

Solve that and you will get 210

Explain, in detail, how you know if these are equivalent.

Answers

Answer:

they are equivalent.

Step-by-step explanation:

to find equivalent fractions, we need to multiply the numerator and denominator of the first fraction by the same number. this creates an equivalent fraction. 5 goes into 15 3 times, and 8 goes into 24 3 times. this shows that if we multiply both the numerator and denominator of the first fraction by 3, then we end up with the second fraction, proving that they are the same. hope this helps!

Holly has $15 to buy a gift for her brother. She found a stuffed animal that cost $12.50. With 10.1% sales tax added on, what is the sale tax? What is the total cost of the stuffed animal with tax included?

Answers

ANSWER: $13.76

Explanation:

We know the stuffed animal cost $12.50 and we know the sales tax is 10.1%. So we need to find 10.1% of 12.50. In math of means multiplication so it’s

10.1 x 12.50

Multiply like normal to get 1.2625

I’m assuming you round and get 1.26.

Now we know the sales tax and the price of the stuffed animal. But to know what it is after the sales tax we need to add.

1.26 + 12.50 = $13.76
The Answer is $13.76

Which of the following is closest to how much she will earn in hourly wages and commission for those two weeks?
A.
$721
B.
$560
C.
$161
D.
$217

Answers

Answer:

A

Step-by-step explanation:

First, I'm going to work out the hourly wages for the 2 weeks.

$8 x 70hours = $560

(8 x 7 = 56 x 10 = 560)

Next, work out the commision.

10% of $1612

1612 ÷ 10 = 161.2

Finally, add together both the hourly wages and commision.

161.2 + 560 = 721.2

Round it down to a whole number.

721 , Add on the dollar sign.

It's answer A, $721.

A. 721
I’m pretty sure it’s 721$

A phone company advertises a new plan in which the customer pays a fixed amount of $ 25 per month for unlimited calls in the country and $ 0.10 per minute for international calls . If a customer paid 120 dollars , how many international minutes did they use ?

Answers

Answer: The answer would be 950 international minutes. Only if assuming that this is in one month since the question doesn't give much detail.

Step-by-step explanation:

X would be used to represent the number of months.

25+0.10x=120

0.10x=95

950 international minutes used

Answer:

950

Step-by-step explanation:

An equation to model this scenario would be: y = 0.1x + 25

y would mean the amount of money paid depending on x, which is the number of minutes.

In this problem, we know the amount of money. So we know y is 120.

We can then put 120 into the equation to find x.

120 = 0.1x +25  

95 = 0.1x

x = 950

Therefore, x is 950.

The area of a square root is 2.25m2. what is the length of each side of the square?

Show work pls, thank you.

Answers

Answer:

1.5 m

Step-by-step explanation:

Area = length * width

or we can say

Area = side1*side2

since they are the same we can say

Area = side * side

which also means area = side^2

so we have the area and we want the side, we need the inverse operation for squaring something. the inverse of squaring something is square rooting

so

sqrt(Area) = side

so

side = sqrt(2.25)

= 1.5 m

You mix 23.385 grams of sugar and 12.873 grams of baking soda in a glass container for an experiment. You place the container on a scale to find that the total mass is 104.2 grams. What is the mass of the container

Answers

23.385+12.873=36.258
104.2-36.258=67.942
Answer=67.942

The mass of the container is 67.942 grams.

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that amount of sugar is 23.385 grams, the amount of soda is 12.873 and the total mass is 104.2 grams.

The weight of the container will be calculated as below:-

Total weight of sugar and sods = 23.385+12.873=36.258

Weight of container = 104.2-36.258=67.942

Weight of container = 67.942 grams

Therefore, the mass of the container is 67.942 grams.

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?
