Anthony found a number that is 20% of 30% of 400 what percent of 45 is the number that Anthony found

Answers

Answer 1

Answer:

For this case we have:

1st step:

We look for 30% of 400 by a rule of three of the form:

400 -------> 100%

x -----------> 30%

Where x is given by the number that represents 30% of 400.

We have:

$x =((30 * 400))/(100)\nx = 120$

2nd step:

We search for 20% of the number found, that is, $x = 120$ , using a rule of three:

120 -------> 100%

y -----------> 20%

Where y is given by the number that represents 20% of 120.

We have:

$y =((20 * 120))/(100)\ny = 24$

So, the number that Anthony found is 24.

3rd step:

According to the statement, we must find the% that represents the number of Anthony, based on the number 45. Through a rule of three we have:

45 -------> 100%

24 -----------> z%

Where z is given by the% that represents Anthony's number, knowing that 45 represents 100%.

We have:

$z =((24 * 100))/(45)\nz = 53.33$ %

Answer:

The number of Anthony represents 53.33% of 45.

0.185 repeating as a fraction??

Answers

The number 0.185 repeating can be represented as the fraction 185/999 in its simplest form.

What is the fraction?

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

To convert this number into a fraction, we can use the following steps:

Let x = 0.185185185...

Multiply both sides of the equation by 1000 to move the decimal point three places to the right:

1000x = 185.185185...

Subtract the left side of the equation from the right side:

1000x - x = 185.185185... - 0.185185185...

Simplify the right side of the equation by canceling out the repeating decimals:

1000x - x = 185

Combine like terms on the left side of the equation:

999x = 185

Solve for x by dividing both sides of the equation by 999:

x = 185/999

Therefore, 0.185 repeating can be represented as the fraction 185/999 in its simplest form.

If a test has 95 questions how many points would each question be worth? Using your answer how many could you miss without going below an 80?

Answers

One can miss up to 24 questions and still achieve an 80% score.

In order to calculate the points each question is worth and determine how many questions you can miss while maintaining an 80% score.

To find the points each question is worth, we divide the total points by the number of questions. Let's assume the test is out of 100 points, which is a common scale. Therefore, each question would be worth $(100)/(95)$ or approximately 1.05 points.

Now, let's determine how many questions you can miss while still achieving an 80% score (which is 80 out of 100 points). We'll set up an equation to solve for the maximum number of questions you can miss, denoted by "x":

$80 = (100 - x)/(95) * 100$

To solve for "x," first, we'll simplify the equation:

$80 = (10000 - 100x)/(95)$

Next, we'll isolate "x" by multiplying both sides by 95:

$7600 = 10000 - 100x$

Now, isolate "-100x" by subtracting 7600 from both sides:

$-2400 = -100x$

Finally, divide both sides by -100 to solve for "x":

$x = (-2400)/(-100) = 24$

So, you can miss up to 24 questions and still achieve an 80% score.
