A student answered 46 problems on the test correctly and received a grade of 88%. how many problems were on the test if all problems we wear the same number of points?

Answers

Answer 1

Answer: The answer is 52 questions

Answer 2

Answer: so to find percentages we do the part over the whole. So in this equations we do

(answered correctly)/(total number of questions) * 100=grade

answered correctly = 46
Total number problems = x
where x is the number we don't know
and
grade is 88

(46)/(x) = .88

multiply both sides by x

we get

46 = .88x

we just need to simplify
46/.88 = x
52.27 = x

How do you write 72.5% as a fraction in simplest form

What is the fundamental principle of multiplication?

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We have to write 72.5% as a fraction in simplest form.

So we put 72.5 over 100

That is (72.5/100)

Now multiply the top and the bottom by 10 to get rid of the decimal, giving;

725/1000

Then divide the top and bottom by like factors,

5 (145/200)

Then another 5,

29 over 40 (29/40)

Hence, the 72.5% as a fraction in simplest form is (29/40)

So you put 72.5 over 100 (72.5/100)
Then you multiply the top and the bottom by 10 to get rid of the decimal, giving you 725/1000
Then you divide the top and bottom by like factors, starting with 5 (145/200)
Then another 5, giving you 29 over 40 (29/40)

Alan purchased 16 shares of company stock for $390.40. A month later, the total value of his shares fell to $291.20. What is the current price per share if each share costs the same?

Answers

i think that the current price for each share would be $18.20 if the total value went down to $291.20.

So it looks like when Alan initially purchased his company stock, the price per share was $24.40 ($390.40/16).
Being that the stock has fallen, the stock price is now $18.20 ($291.20/16).

Hope this helps.

Find the result when 20 is increased by 95%.

Answers

10 percent is 2 and 5 percent is 1. 2 times 9 is 18. That is 90 percent. 18 plus 1 is 19 which is 95 percent. 20 plus 19 is 39 so the answer is 39.

Final answer:

To find the result when 20 is increased by 95%, you will need to calculate 95% of 20, which is 19, and then add it to 20. The result is 39.

Explanation:

To find the result when 20 is increased by 95%, you will need to calculate 95% of 20 and add it to 20. Here's how:

Calculate 95% of 20: 0.95 * 20 = 19
Add 19 to 20: 20 + 19 = 39

So, the result when 20 is increased by 95% is 39.
