Answer:
$84.50
Step-by-step explanation:
Add the amounts:
$63.48 + $52.02 = $115.50
Two $100 bills add to $200.
To find the change, subtract the total cost from the amount of money handed over.
$200 - $115.50 = $84.50
Molly should give him $84.50. Thus option B is the correct answer.
The change given must be equal to the balance left after deducting the price of the goods from the total money received.
In this case,
Price of goods = Price of DVD player + Price of five DVDs
= $63.48 + $52.02
=$115.50
Total Money Received = 2 x $100 = $200
Therefore, Change = Total Money Received - Price of goods
= $200 - $115.50
= $84.50
Joseph and Raquel are building a scale model of the Alamo Mission for their Texas history project using a scale in which 2 inches represents 30 feet. The enclosed area of the Alamo Mission was 480 feet long and 160 wide.
What should the length of the enclosed area of the scale model be in inches?
Responses
Representative fraction is a form of scale that can be used to change the size of an object to form an image. The required length is 32 inches.
A scale is a fraction of numbers that can be used to either increase or decrease the size of a given object. It is majorly referred to as representative fraction in scale drawing.
Representative fraction = [tex]\frac{length on drawing}{original length}[/tex]
In the given question, we have;
12 inches = 1 feet
x inches = 30 feet
So that:
x = 30 x 12 inches
= 360 inches
representative fraction = [tex]\frac{2 inches}{360 inches}[/tex]
= 5.56 x [tex]10^{-3}[/tex]
Thus, given that the length of the Alamo Mission is 480 feet long. Then:
480 feet = 480 x 12 inches
= 5760 inches
So that,
the required length in inches = 5760 x 5.56 x [tex]10^{-3}[/tex]
= 32 inches
Therefore the expected length of the Alamo Mission is 32 inches.

Manas is half his sister's age.
She is eight years younger than
Uncle Mike. Mike is the sum of a
dozen and a score.
In how many years time will the sum of Manas' age and his
sister's age be 48 years?
Answer: In 6 years the sum of Manas' age and his sister's age will be 48 years.
Step-by-step explanation:
We know that value of a dozen is 12 and the score is 20.
Hence,
Uncle Mike's age = 12+20 = 32 years
Since Manas' sister is 8 years younger than Mike,
Her age = 32 - 8 = 24 years
We know that Manas is half her age. Therefore,
Manas' age = 24 ÷ 2 = 12 years
After x years the sum of Manas' age and his sister's age will be 48 years.
Manas' future age = (12 + x) years
His sister's future age = (24 + x) years
The Sum of their ages is 48 years. Hence,
(24 + x) + (12 + x) = 48
36 + 2x = 48
2x = 48 - 36
2x = 12
x = 12 ÷ 2
x = 6
Therefore, in 6 Years sum of their ages is 48 years.

For what value of k are the graphs of 12y = 9x + 8 and 4y = k(x + 4) parallel?
perpendicular? I HAVE THE ANSWER, just need step to step explanation on how to solve it (pls be clear, answers in pic)
Answer:
parallel: k = 3perpendicular: k = -16/3Step-by-step explanation:
You want to know the values of k that make the line 4y = k(x +4) either parallel or perpendicular to the line 12y = 9x +8.
ParallelThe slopes of parallel lines are the same. When the equation of a line is written in "y =" form, the slope is the coefficient of x. Here, the two equations written in that form are ...
y = k/4x +1y = 3/4x +2/3For parallel lines, we want to choose the value of k so that the slopes are equal:
k/4 = 3/4
k = 3 . . . . . . . . multiply by 4
PerpendicularThe slopes of perpendicular lines have a product of -1. This means we want to choose k so that ...
(k/4)(3/4) = -1 . . . . . the product of slopes k/r and 3/4 is -1
k = -16/3 . . . . . . . . . multiply by 16/3

if l lll m, solve for x (9x+25)° (13x-19)° (17y+5)°
The angles, x = 11 and y = 3,if l ll m,
What are angles?When two rays are linked at their ends, they create an angle in geometry. The sides or arms of the angle are what are known as these rays.
When two lines meet at a point, an angle is created.
An "angle" is the measurement of the "opening" between these two rays. It is symbolized by the character. The circularity or rotation of an angle is often measured in degrees and radians.
Angles are a common occurrence in daily life.
Angles are used by engineers and architects to create highways, structures, and sports venues.
According to our question-
A transversal intersects the parallel lines marked by the letters "l" and "m.
The two suplementary angles have the radii (13x - 19°) and (17y + 5)°, respectively.
Thus, (13x - 19)° plus (17y + 5)° equals 180°.
13x + 17y = 180 + 14
13x + 17y = 194 ————(1) (1)
The comparable angles are (9x + 25) and (13x - 19).
Consequently, (9x + 25) = (13x - 19)
9x - 13x = -19 - 25
-4x = -44
x = 11
By changing equation's value for 'x' (1),
13x + 17y = 194
13(11) + 17y = 194
17y = 194 - 143
17y = 51
y = 3
As a result, the solution will be x = 11 and y = 3.

a solid is formed by adjoining two hemispheres to the ends of a right circular cylinder. the total volume of the solid is 12 cubic centimeters. find the radius of the cylinder that produces the minimum surface area of the solid.
11.4 centimeters is the radius of the cylinder .
What does volume mean in plain terms?
The capacity of a solid shape is determined using volume, a three-dimensional quantity.
It implies that a closed figure's volume determines how much three-dimensional space it can fill.
The volume of a cylinder is given by
v = πr²h
The total volume of the two hemispheres is given by
v' = 2× 2/3 πr³
v' = 4/3 πr³
Now, the total volume of the solid is given by:
[tex]V_{T}[/tex] = πr²h + 4/3 πr³
Now, substitute the value of the total volume in the above expression and then solve for h.
12 = πr²h + 4/3 πr³
h = 12/πr² - 4r/3
Now, the surface area of the curved surface is given by:
A = πrh
Now, the surface area of the two hemispheres is given by
A' = 2 × (2πr² )
A' = 4πr²
Now, the total area is given by
[tex]A_{T}[/tex] = 2πr ( 12/πr² - 4r/3) + 4πr²
Simplify the above expression.
[tex]A_{T} =[/tex] 24/r + 4πr²/3
Now, differentiate the total area with respect to 'r'.
[tex]\frac{dA_{T} }{dr}[/tex] = -24/r² + 8πr/3
Now, equate the above expression to zero.
0 = -24/r² + 8πr/3

what is polynomial?Algebraic expressions called polynomials include constants and indeterminates.
Polynomials can be thought of as a type of mathematics. Nearly all branches of mathematics employ them to express numbers, and calculus is one of those branches where they play a crucial role.
A specific kind of expression is a polynomial. A mathematical statement without the equals symbol (=) is called an expression.
An algebraic expression known as a polynomial requires that all of its exponents be whole numbers.
Any polynomial must have variable exponents that are non-negative integers.
Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.
According to our question-
-3x3 + 2x2 + 11x - 20 + (10/(-x-7)) = 3x4 + 19x3 - 25x2 - 57x + 150
In order to perform synthetic division, we must first remove the minus sign from the divisor and write out
-7 | -3 -19 25 57 -150
| 21 -14 -77 140
-3 2 11 -20 -10
obtain that
3x4 + 19x3 - 25x2 - 57x + 150 / (-x-7) is equivalent to 3x4 - 19x3 - 25x2 - 57x + 150 / (x+7) is equivalent to 3x3 + 2x2 + 11x - 20 + (10/(-x-7)).

How to solve three variable equations?
In comparison to equations with two variables, a three-variable linear equation requires a little more work to solve. The extra variable is the cause of this complexity.
Even if there are various ways to solve this kind of equation, the elimination technique is still the simplest.
To solve three variable linear equations using the elimination approach, follow these steps:
1. Avoid using fractions and decimals and write all the equations in standard form.
2. Pick an appropriate variable to remove.
3. Remove the chosen variable from any two of the three equations.
4. Choose another set of the two equations, and then take the same chosen variable out.
5. For the two variables they each include, solve the two equations from stages three and four.
6. Replace the answer in fifth step.
7. Reverify by putting them again in the equation.
So according to these given Equations we have to find the value of x, y and z respectively,
-2x + 15y + z = 44
4x + 3y + 3z = 18
-3x+6y-z = 8
After solving these three equations we do not get any solutions.

a right triangle's height is 3 times the length of its base. if the area of the triangle is 150, what is its height?
The height of the right triangle if the area of the triangle is 150 square units = 30 units
In this question, we have been given a right triangle's height is 3 times the length of its base.
We need to find the height of the right triangle if the area of the triangle is 150 square units.
Let h be the height and b is the base of the right triangle.
A right triangle's height is 3 times the length of its base.
So we get an equation,
h = 3b ............(1)
Using the formula of area of right triangle,
A = 1/2 * b * h
150 = 1/2 * b * 3b .........(from equation (1))
300 = 3b^2
b^2 = 100
b = 10
Subatitute above value of b in equation (1),
h = 3 * 10
h = 30 units

The smallest residual is 14, and the largest residual is 51. The largest residual corresponds to an outlier in the data.
B)
The smallest residual is 14, and the largest residual is 51. The largest residual does not correspond to an outlier in the data.
C)
The smallest residual is 18, and the largest residual is 45. The largest residual corresponds to an outlier in the data.
D)
The smallest residual is 18, and the largest residual is 45. The largest residual does not correspond to an outlier in the data.
Based on the information provided, the correct statement is: The smallest residual is 14, and the largest residual is 51. The largest residual corresponds to an outlier in the data.
A residual is the difference between the actual value of the dependent variable (in this case, the number of customers) and the predicted value of the dependent variable based on the model (in this case, the line of fit). In other words, it is the error or deviation between the observed data and the model.
In this case, the smallest residual is 14, and the largest residual is 51. This means that the model is most accurate when predicting the number of customers on days with temperatures close to 82°F and least accurate when predicting the number of customers on days with temperatures close to 91°F. The large residual of 51 corresponds to an outlier in the data, which means that the model is not a good fit for this data point and may not accurately predict the number of customers on days with temperatures close to 91°F.
Option A is correct because it correctly describes the range and magnitude of the residuals and identifies the largest residual as corresponding to an outlier in the data.
