roy gets 10% extra time in school exams. If Roy gets 1 hour 33 minutes and 30 seconds to complete his maths exam, how long do most students get.
Answers
Answer:
1 Hour 25 Minutes
The time that most of the students get is 1 hour and 25 minutes, computed using fractions and percentages.
What are fractions?Fractions are a relational representation of certain parts of a quantity, to the total parts of that quantity.
Written as a/b, read as "a by b", functions as a divided by b, represents a fraction a over b, where a is the numerator and b is the denominator.
What are percentages?Percentages are a fractional representation of a quantity, where the whole quantity is fixed to be 100.
Fractions are converted to percentages by multiplying them by 100, while percentages are converted to fractions by dividing them by 100.
How to solve the question?In the question, we are informed that Roy gets 10% extra time in school exams.
We are asked for the time that is given to most of the students if Roy gets 1 hour 33 minutes and 30 seconds.
For standardization, we work in seconds.
We assume the required time to be x seconds.
Time given to Roy:
30 seconds implies 30 seconds,
33 minutes implies 33*60 = 1980 seconds,
1 hour implies 1*60*60 = 3600 seconds.
Thus, the total time given to Roy = 30 + 1980 + 3600 = 5610 seconds.
We are informed that Roy gets 10% extra time in school exams.
Thus, the time given to Roy = Normal time + 10% of normal time,
or, 5610 = x + 10% of x,
or, 5610 = x + 10/100 of x {percentages are converted to fractions by dividing them by 100},
or, 5610 = x + x/10,
or, 5610 = 11x/10,
or, x = 5610*10/11 = 5100.
Thus, the time given to most of the students = 5100 seconds = 5100/60 minutes = 85 minutes = 1 hour and 25 minutes.
Thus, the time that most of the students get is 1 hour and 25 minutes, computed using fractions and percentages.

Step-by-step explanation:
Thanks!!!!!!
Answer:
2.5 * 10^14
Step-by-step explanation:
(5 x 10⁶) * (5 x 10⁷)
= (5 * 1000000) * (5*10000000) Step 1
tip : When multiplying tens with exponents, consider adding zeros according to the exponent the 10 is raised to. For example, 10⁶ would be 1000000 (six zeros)
= (5000000) * (50000000) Step 2
= 250000000000000. Step 3
= 2.5 * 10^14 Step 4 move your decimal point to the left (14 times) until you you condense your value into a smaller decimal (2.5)

simplify 36 - 4.5x + 36 to -4.5x + 72
simplify 102 - 7.5x - 60 to -7.5x + 42
add 7.5x to both sides
simplify -4.5x + 72 + 7.5x to 3x + 72
subtract 72 from both sides
simplify 42 - 72 to -30
divide both sides by 3

Answer: B
Step-by-step explanation:
The origin is the center of the 2 bold lines. As you can see, the square is 1 unit right and then 2 units up. The star is 2 units left and 1 unit up. And the triangle is 2 units down and 2 units left.
square: 1 then 2
star: 2 then 1
triangle: 2 then 2.
From this you can see that the square and the star are the same distance from the origin.
So the answer is B.
