The value of 1936 divided by 8 in long division is 242.
What is long division?Long Division is a method for dividing large numbers that divides the task into numerous phases that follow a sequence. Just like in conventional division problems, the dividend is divided by the divisor, yielding the quotient and, in some cases, a remainder.
The steps are:
Step 1: Take the first digit of the dividend from the left.
Step 2: Then divide it by the divisor and write the answer on top as the quotient.
Step 3: Subtract the result from the digit and write the difference below.
Step 4: Bring down the next digit of the dividend
Using the above step the division is 242.

Since it is a right triangle, you can use the trigonometric ratio sin(θ) to solve the exercise:

In triangle DEF, m∠D = (3x + 27)°, m∠E = (4x + 22)°, and m∠F = 68°. Determine the degree measure of the exterior angle to ∠D.

58°
122°
126°
The sum of all interior angles of a triangle is 180° thus the measure of the exterior angle to ∠D is 126° so option (D) is correct.
What is a triangle?
A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are 3 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°.
So, m∠D + m∠E + m∠F = 180°
(3x + 27) + (4x + 22) + 68 = 180
7x + 49 + 68 = 180
7x = 63
x = 9
So, m∠D = (3(9) + 27)° = 54°.
The exterior angle of D = 180- 54 = 126°.
Hence "The sum of all interior angles of a triangle is 180° thus the measure of the exterior angle to ∠D is 126°".

community gym charges a $50 membership fee and a $60 monthly fee. Workout gym charges a $225 fee and a $5 monthly fee. After how many months will the total amount paid to both gyms be the same?
Step 1 : Let's review the information given to us to answer the problem correctly:
Community Gym = $50 (Membership fee) + $ 60 (Monthly fee)
Workout Gym = $ 225 (Membership fee) + $ 5 (Monthly fee)
Step 2: Let's write the equation to answer the question, as follows:
Let x to represent the number of months that the total amount paid to both gyms will be the same
Community Gym = Workout Gym
Therefore,
50 + 60x = 225 + 5x
Like terms:
60x - 5x = 225 - 50
55x = 175
Dividing by 55 at both sides:
55x/55 = 175/55
x = 3.18 months
0.18 * 30 = 5.4 days
Step 3: Interpretation of the answer
Approximately after 3 months and 5 days and a half the total amount paid to both gyms will be the same

it is given that, the relation between the price of honey and jar capacity is in the given graph.
so, we have three points on the graph,

At a school concert the total value of tickets sold was $3990. Student tickets sold for $8 and adult tickets sold for $11. The number of adult tickets sold was 6 less than 4 times the number of student tickets. Find the number of student tickets sold.
The number of student tickets sold is 78.
Given,
The number of student tickets sold = x
The number of adult tickets sold = 4x - 6
Total value of tickets sold = $3990
Value of one student ticket = $8
Value of one adult ticket = $11
Now, we have to find the number of student tickets sold:
Here,
The expression :8x + 11(4x - 6) = 3990
Solve the expression:
8x + 44x - 66 = 3990
52x - 66 = 3990
Add 66 to both sides
52x - 66 + 66 = 3990 + 66
We get,
52x = 4056
Divide 52 on both sides
52x / 52 = 4056/52
That is,
x = 78
Therefore,
The number of student tickets sold is 78.

a casting weighted 148 lb out of the mold. it weighed 141 lb after finishing. what percent of the weight was lost in the finishing?
The amount of weight lost will be equal to 4.72%.
Percentage may be defined as a form of expressing a number as a fraction of hundred. To find the percentage of a number we divide the number by the total amount and then multiply the answer with hundred. The initial weight of the casting was 148 lb and the final weight is 141 lb. To find the percentage we use the formula
Percentage lost = [(Final weight - Initial weight)/Initial weight] × 100
Percentage lost = [(141 - 148)/148] × 100
Percentage lost = ( -7/148) × 100
Percentage lost = -0.0472 × 100
Percentage lost = -4.72% and since we write the absolute value therefore, Percentage lost = 4.72%.

The two-way table shows the number of students that do or do not do chores at home and whether they receive an allowance or not. Allowance No Allowance Do Chores 13 3 Do Not Do Chores 5 4 a. How many total students do chores? b. What is the relative frequency of students that do chores and get an allowance to the number of students that do chores? Round to the nearest hundredth if necessary.
Given the table showing the number of students who do or do not perform chores, and who do or do not receive an allowance, we can add the numbers along the rows and columns, as shown in the diagram below:
Now, that we have summed the numbers along the vertical and horizontal directions, we can now proceed to answer the questions asked.
a.) The total number of students who do chores is equal to the horizontal sum of the numbers in the 'DO CHORES' row. This value is 16
Thus, 16 students do chores
b) The relative frequency of the students that do chores and get an allowance to the number of students that do chores is simply the ratio of the value in the cell that represents an intersection of the first 'DO CHORES' row, and the first 'ALLOWANCE' column, to the value that represents the sum of all the students that do chores ( i.e, the value at the end of the first row).
Thus, this is equal to = 13/16
Therefore, 13/16 is the relative frequency of the students that do chores and get an allowance to the number of students that do chores
c) The relative frequency of the students that do not do chores nor get an allowance to the total number of students, is simply the ratio of the value in the cell that represents an intersection of the second 'DO NOT DO CHORES' row, and the second 'NO ALLOWANCE' column, to the sum of the values in the last row or the last column.
Thus, this is equal to = 4/( 18 + 7) OR 4/(16 + 9) both of which is still 4/25
Therefore, 4/25 is the relative frequency of the students that do not do chores nor get an allowance to the total number of students.
d) The students who do not do chores are a total of 9
Of this 9, the number of students that do receive their allowance fall under the 'ALLOWANCE' column, and is equal to 5.
Therefore, expressed as a percentage of those who do not do their chores, the students who do not get an allowance are = (5/9) * 100 = 55% ( to the nearest whole number)
Thus 55% of students who do not do chores do not get an allowance

What actually does probability mean?
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number ranging from zero and 1, where, roughly, 0 denotes the event's impossibility and 1 represents certainty.Formula of total frequency is,
Total = f₁ + f₂ + f₃ + f₄ +...............n∑fi
The total frequency is,
total = n∑i=2 fi ⇒ 262 + 992 + 587 + 313 + 52
The total number of people prepared for a long-term power outage, natural disaster, or terrorist attack is obtained by taking the sum of the all frequencies.
probability = N(E)/N(S)

That is, N(A) = 262
