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.

share out £20 between bill and sue in the ratio 3:2
Answer:
12:8
Step-by-step explanation:
Bill receives £12, and Sue receives £8.
In order to divide £20 between Bill and Sue in the ratio 3:2, we first need to find the total number of parts in the ratio. The sum of the parts in a 3:2 ratio is 3 + 2 = 5.
Next, we determine the value of one part by dividing the total amount (£20) by the total number of parts (5): £20 ÷ 5 = £4.
Now, we can allocate the money to Bill and Sue according to their shares in the ratio. For Bill, who gets 3 parts, we multiply his share of one part (£4) by 3: £4 × 3 = £12. For Sue, who gets 2 parts, we multiply her share of one part (£4) by 2: £4 × 2 = £8.
Thus, Bill receives £12, and Sue receives £8.
In mathematical terms, we can represent the division of £20 between Bill (B) and Sue (S) as follows:
Let the ratio be represented as B:S = 3:2.
Total parts in the ratio = 3 + 2 = 5.
Value of one part (Vp) = Total amount / Total parts = £20 ÷ 5 = £4.
Amount received by Bill (Ab) = 3 parts × Vp = 3 × £4 = £12.
Amount received by Sue (As) = 2 parts × Vp = 2 × £4 = £8.
Thus, Bill receives £12, and Sue receives £8.
In summary, when dividing £20 between Bill and Sue in the ratio 3:2, we follow the steps of finding the total parts in the ratio, calculating the value of one part, and then distributing the amount based on each individual's share in the ratio.

Answer:
[tex]\frac{15}{20} x-2=\frac{8}{20}[/tex]
Step-by-step explanation:
[tex]\frac{3}{4} x-2=\frac{2}{5}[/tex]
3/4 and 2/5 have a common denominator which is twenty so you can rewrite the equation with just knowing that
[tex]\frac{3}{4} =\frac{15}{20}[/tex]
[tex]\frac{2}{5} =\frac{8}{20}[/tex]
[tex]\frac{15}{20} x-2=\frac{8}{20}[/tex]
You can then multiply both sides by twenty to solve this equation.
Hope this helps.

PLEASE ANWSER CORRECTLY!! I WILL MARK BRAINIEST!!
Answer:
A) 33
B) 58
Step-by-step explanation:
A is 33 because supplementary angles add up to 180 in total. 180 - 147 = 33, so its supplementary angle would be 33 degrees.
B is 58 because complementary angles add up to 90 in total. 90 - 32 = 58, so the complementary angle would be 58 degrees.
Answer: 33° and 58°
Step-by-step explanation:
147° and 32°
Two angles are called complementary when their measures add to 90 degrees. (90° - 32°) = 58°
Two angles are called supplementary when their measures add up to 180 degrees. (180°-147°) = 33°

An object containing the point (-6, 10) was moved to the location (12, -2). Which choice best described the translation?
A right 12, down 12
Bright 6, down 10
right 18, down 12
Dright 18, up 12
Answer:
C right 18, down 12
Step-by-step explanation:
Well firstly,
you should focus on the x in both the previous and after location of the object.if you minus 12 from the after point (12,-2) by -6 from the previous point (-6,10) for the object, you'll get 18 which is positive, which means that the object will moves to the right side of the graph →
12 - (-6)
= 18
Next,
you should now focus on the y in both the previous and after location of the object.you should minus -2 by 10 and you'll get -12, which means that the object will moves to the down side of the graph ↓
-2 - 10
= -12
So, the object will move 18 boxes to the right and 12 boxes down to achieve the after, final or last location as stated in the question (12,-2)

Solve for m: m=−(4+m)+2
Answer:
m = - 1
Step-by-step explanation:
m = -4 - m + 2 Combine
m = -2 - m Add m to both sides
m+m = - 2 Combine
2m = - 2 Divide by 2
m = -2/2
m = - 1
m=−(4+m)+2
Simplify both sides of the equation.
m=−(4+m)+2
m=−m+−4+2
m=(−m)+(−4+2)
m=−m+−2
m=−m−2
Add m to both sides.
m+m=−m−2+m
2m=−2
Divide both sides by 2.
2m/2=−2/2
m=−1

The graph number [2], represents a function.
What is a expression? What is a mathematical equation? What is Equation modelling ?A mathematical function is made up of terms (constants and variables) separated by mathematical operators having a dependent and independent variable. A mathematical equation is used to equate two expressions. For any function y = f(x), Domain is the set of all possible values of [y] that exists for different values of [x]. Range is the set of all values of [x] for which y exists.
We have some graphs of relations as shown.
Only the graph number [2], represents a function as for a single value value of [x], a single unique value of [y] exists.
Therefore, the graph number [2], represents a function.
