Find two numbers the quotient between. Then estimate the quotient. 41÷3
AleksandrR [38]

Answer:

The quotient is between 10 and 15, and the exact answer is 13 with the remainder of 2: 13R2.

Step-by-step explanation:

41 ÷ 3 is a very long answer so do 39 ÷ 3 which equals 13 and since you can't divide 2 by three without negatives, just do it as a remainder of 2, or R2, which means the answer is 13 with the remainder of 2, or just 13R2.

In a billiards game, Pete hits a ball that is 20 in. from a wall. The ball travels 34 in. until it hits the wall and bounces to
Novosadov [1.4K]

Refer to the attached image,

Peter hits a ball that is 20 inch from a wall means AB=20 in

A ball travels 34 in until it hits the wall means AC=34 in

It bounces back to a position means CD = 'x' in (Say)

It bounces back to CD which is 16 in from the wall means DE=16 in

We have to calculate the value of 'x'.

Since, ball is reflected from point C. By law of reflection which states the angle of reflection is equal to the angle of incidence.

So, \angle ACF=\angle FCD = y degrees (say)

Since angles BCF and FCE are right angles.

So, \angle BCA=\angle DCE = 90-y^\circ (equation 1)

Now, in triangle ABC and CDE

\angle B=\angle E (Each angle is right angle)

\angle BCA=\angle DCE (From equation 1)

Therefore, triangle ABC is similar to triangle DEC by AA similarity.

So, the ratio of corresponding sides are equal.

\frac{AB}{DE}=\frac{AC}{DC}

Substituting the values,

\frac{20}{16}=\frac{34}{x}

20x = 544

x = 27.2 in

Therefore, the distance, x, the ball traveled after it bounced off the wall to get to the ending position is 27.2 in

In Prof. Johnson's class, the 10 students had the following scores on the last midterm.
timofeeve [1]

Answer: 188 is the outlier

Step-by-step explanation:

Find median of the whole data set. The median is 83.5.

Then find Q1 and Q3. Q1 is 78, Q2 is 96.

Then find the IQR. The IQR is 18.

Find the inner fences of the data set. The inner fences are 51 and 123. Anything that is outside of 51 or 123 is an outlier so 188 is an outlier.

Adnan states if cos30°≈0.866, then sin30°≈0.866.
kiruha [24]

Answer:

Adnan is incorrect because cosx and sin(90 - x) are always equivalent in any right triangle ⇒ first answer

Step-by-step explanation:

In any right triangle there are two acute angles sum of them is 90°

∴ If one of them x°, then the other is (90 - x)°

∵ cos x = adjacent/hypotenuse

∵ sin(90 - x) = opposite/hypotenuse

∵ The opposite of ∠(90 - x) is the adjacent of ∠x

∴ cosx = sin(90 - x)
