In the scenario it implies that you aren't a student and are most likely a teacher or tutor of some sort so the statement "If you go to school, then you are a student is false" because not all students go to school and in your scenario not only students go to school.
A design for a library has a scale of 1/3 in= 1ft. The height of the library in the drawing is 12 inches. What is the
actual height of the library?
A library's design is scaled at [tex]\frac{1}{3}[/tex] inch = 1 feet. The library in the drawing is 12 inches height. The library's true height is 432 inches, or 36 feet.
Given that,
A library's design is scaled at [tex]\frac{1}{3}[/tex] inch = 1 feet.
The library in the drawing is 12 inches height.
We can take [tex]\frac{1}{3}[/tex] inch = 1 feet
1 inch=3 feet = 36 inches.
36 inches is the actual height .
Now actual height of the library is
Multiplication of the height of the library in the drawing is 12 inches and the new height 36 inches.
12[tex]\times[/tex]36=432 inches
We can say 432 inches is equal to 36 feet.
Therefore, 432 inches or 36 feet is the actual height of the library.

Gind the greatest common factor for the list of terms.
98ab^3, 84a, 140b, 112ab
Answer:
14
Step-by-step explanation:
You want the greatest common factor of the terms {98ab^3, 84a, 140b, 112ab}.
Common factorsThere are no variables that are common to all terms. 'a' and 'b' are each common to 3 of the 4 terms, but not all.
The greatest common factor of the constants cannot be larger than the smallest difference of the constants. That difference is ...
98 -84 = 112 -98 = 14
Since 14 is a divisor of all of the constants, 14 is the greatest common factor.

14 is the perimeter of the rectangle .
What does a rectangular 's perimeter mean?
Considering that the polygon's perimeter is equal to the sum of its sides. As a result, the perimeter (P) of a rectangle is given by P = the total of its four sides. P = a + b + a + b (Opposite sides of rectangle are equal).The answer provided below has been developed in a clear step by step manner.
Step: 1
Given, A(x) = x(14-x)
Comparing with A = lw , we have
Length , l = x and
Width , w = 14 - x
Step: 2
We know,
Perimeter of rectangle ,
p = 2( l + w )
p = 2 ( x + 14 - x )
p = 28

When an automobile travels uphill or downhill on a highway, it experiences a force due to gravity. This force in pounds is called grade resistance and is modeled by the equation below, where theta is the grade and W is the weight of the automobile.
F = Wsin theta
A 2710-lb car traveling uphill has a grade resistance of 160 lb. What is the angle of the grade?
theta =__.
(Type your answer in degrees. Round to the nearest hundredth as needed.)
Based on the calculations, the angle (θ) of the grade to the nearest hundredth is equal to 3.38 degrees.
What is an equation?An equation can be defined as a mathematical expression which shows that two (2) or more thing are equal.
In Science, grade resistance simply refers to force in pounds and can be modeled by the following equation:
F = Wsinθ
Where:
F represents the grade resistance or force in pounds.θ represents the grade W represents the weight of a physical object.Making theta (θ) the subject of formula, we have:
θ = sin⁻¹(F/W)
Substituting the given parameters into the formula, we have;
θ = sin⁻¹(160/2710)
θ = sin⁻¹(0.0590)

The selling price of an item is480 $. It is marked down by 10%, but this sale price is still marked up from the cost of $360. Find the markup from cost to sale price
Answer: $72
Step-by-step explanation:
Oddly worded question but if I understand it correctly we need to find the marked down price and subtract $360 from it.
It is 10% off so an easy way to do the math is to find what 90% of $480 dollars is.
.90 * 480 = $432
Then we subtract $360 from this sale price.
$432 - $360 = $72

According to the solving the LHS = RHS this shows the equality symmetric property.
52 = 52.
What is the difference between LHS and RHS?LHS is an informal shorthand again for the left-hand side of the an equation in mathematics. Likewise, RHS refers to the right-hand side. Because equality is symmetric, both sides share the same value, expressed differently.
What is the idea of equality?Given the "equality" (=) relation and a = b, if b = a holds true for all a and b, equality is said to be symmetric. For all of a and b, the assertion is TRUE (no counterexample can be found). This is known as the equality symmetric property.
According to the given data:-21-17+25+65=52
Proving that both LHS = RHS :

The length of a certain rectangle is 10m greater than twice its width. If the width were reduced by 20m and the length increased by 100m, the perimeter of the new rectangle would be twice the perimeter of the original rectangle. What are the dimensions of the original rectangle?
The dimensions of the original rectangle is a length of 56.66 meter and width of 23.33 meter.
What is perimeter?Perimeter is the sum of all the sides of a two dimensional polygon or shape.
For first rectangle let x represent width:
Length = 2x + 10; width = x
Perimeter = 2(length + width)
Perimeter = 2(2x + 10 + x) = 6x + 20
For second rectangle:
Length = 2x + 10 + 100 = 2x + 110; width = x - 20
Perimeter = 2(length + width)
Perimeter = 2(2x + 110 + x - 20) = 6x + 180
the perimeter of the new rectangle would be twice the perimeter of the original rectangle. Hence:
6x + 180 = 2(6x + 20)
x = 23.33 m, length = 2x + 10 = 56.66
The dimensions of the original rectangle is a length of 56.66 meter and width of 23.33 meter.

Use z scores to compare the given values.
K
In a recent awards ceremony, the age of the winner for best actor was 31 and the age of the winner for best actress was 42. For all best actors, the mean age is 42.4 years and the
standard deviation is 8.2 years. For all best actresses, the mean age is 31.6 years and the standard deviation is 10.3 years. (All ages are determined at the time of the
awards ceremony.) Relative to their genders, who had the more extreme age when winning the award, the actor or the actress? Explain.
Since the z score for the actor is z= and the z score for the actress is z-, the
had the more extreme age.
So the best actor's age deviates from the mean, he receives the award at the most extreme age.
What is defined as the z score?The z-score of a way of measuring X in a set with mean and standard deviation is given by: z = (x - μ)/σ.The Z-score indicates how far the measure deviates from the mean. After determining the Z-score, we examine the z-score table to determine the p-value connected with this z-score. This p-value represents the probability also that measure's value is less than X, or the percentile of X. Subtracting 1 from the p-value yields the probability that measure's value is greater than X.In response to this question:
Whichever z-score does have the highest absolute value, such that, the one that deviates the most from the mean, has a most extreme age.
Best actor: 31 years old, so.
The mean age of the best actors is 42.2 years, with a standard deviation of 8.2 years.
z = (x - μ)/σ
Put the values;
z = (31 - 42.2)/ 8.2
z = -1.36
Best actress:
So, at the age of 42,
The mean of the best actresses is 31.6 years, with a standard deviation of 10.3 years.
z = (x - μ)/σ
Put the values;
z = (42 - 31.6)/10.3
z = 1.01
Thus, Because the best actor's age is further from the mean, he has the most extreme age when receiving the award.
