Answer:

1 Hour 25 Minutes

The time that most of the students get is 1 hour and 25 minutes, computed using fractions and percentages.

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.

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.

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.

Answer:

3t + 81

Step-by-step explanation:

1. First, let's simplify 7t+6w−4t+2w

2. As you can see, the first choice matches with our solution.

Therefore, 3t + 81 is equivalent to 7t+6w-4t+2w.

Answer:

[tex] \sf \: a) \: 3t + 8w[/tex]

Step-by-step explanation:

Now we have to,

→ Find the equivalent expression.

The expression is,

→ 7t + 6w - 4t + 2w

Let's simplify the expression,

→ 7t + 6w - 4t + 2w

→ 7t - 4t + 6w + 2w

→ (7t - 4t) + (6w + 2w)

→ (3t) + (8w)

→ 3t + 8w

Hence, the answer is 3t + 8w.

Answer is in the picture. hope it helps

The sum of all three interior angles of a triangle is 180° thus the measure of x for the given triangle is 8 therefore,∠E = 75°,∠D = 38°, and ∠F = 67°.

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

It is known that the sum of all three angles inside a triangle will be 180°.

Therefore, ∠E + ∠F + ∠D = 180°.

Given that, ∠E = 9x + 3,∠F = 11x -21 and  ∠D = 5x - 2

So, 9x + 3 + 11x - 21 + 5x - 2 = 180

25x - 20 =180

25x = 200

x = 8

So,

∠E = 9(8) + 3 = 75°

∠F  = 11(8) - 21 = 67°

∠D = 5(8) -2 = 38°

Hence "The sum of all three interior angles of a triangle is 180° thus the measure of x for the given triangle is 8 therefore,∠E = 75°,∠D = 38°, and ∠F = 67°".

Explanation:

The angles marked with a single arc pair up and are congruent (angles ACB and DFE). This forms one "A" of "ASA". The other "A" refers to the angles BAC and EDF as shown by the double arcs.

The "S" refers to the pair of congruent sides between the angles mentioned. Specifically, the diagram shows that AC = FD based on the tickmarks on those segments.

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

simplify 30/3 to 10

Answer:

Star and square

Step-by-step explanation:

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.

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)
