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%.

ERROR ANALYSIS: Student A says there is no solution to the graphed system of equations. Student B says there is one solution. Which student is correct? Why?
Then, to solve the exercise, we need to know the slope of each line. The slope of a line is the measure of the steepness of a line.
The graph shows that the red line has a greater steepness than the blue line. Thus, the lines have different slopes. Also, two lines are parallel if they have the same slope. Since these lines have different slopes, they are not parallel.
Therefore, student B is correct because the lines are not parallel, so they will intersect.

In order prove that the triangles are similar by the SAS similarity theorem, it needs to be proven that A. J measures 60°.
What is SAS Similarity Theorem?The SAS Similarity Theorem states that two triangles are similar if their included angles are congruent and their two sides are proportionate to one other. Triangle congruence and resemblance are both criteria for SAS.
The triangles are congruent if two sides and the included angle of one triangle are equivalent to two sides and the included angle of another triangle.
In this case, the length of side FE is 40 and the length of side IH is 20. This gives a value of 60. Therefore, J should measure 60°.

The frequency distribution on the right shows the resultsUse the table to answer the following question. What is the probability that the next person surveyed is very prepared?
The probability the next person surveyed is very prepared is 0.119.
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)

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,
A(4,5), B(10,12.5) and C (15,19)
so, price of 4 oz = 5 $
price of 1 oz = 5/4 = 1.25 $
price of 10 oz = 12.5
price of 1 oz = 1.25 $
price of 15 oz is 19 $
price of 1 oz is 19/15 = 1.26 $

Graph her points on the number line.
Iman will be on - 3 on the number line after the game.
A number line is a representation of a graduated straight line that is used to represent real numbers visually. It is assumed that every point on a number line corresponds to a real number and that every real number corresponds to a point.
When laying a game, Iman earns 2 points on one turn and losses 5 points on the next turn.
Now, let's say Iman started from zero on the number line,
Then, on the first turn, she earns 2 points.
So, the number of points Iman has will be:

After the next turn she losses 5 points.
x = 2 - 5 = - 3

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
