Answer:
Curtis will get $38.40 back
Step-by-step explanation:
First, we need to find out how much "real" money he has. The equation I did was:
50 + 30 + 30 + 8 = 118
Next, we must convert this into dollars, by multiplying by 0.325675
118 x 0.325675 = 38.42965
We round 38.42965 to the nearest penny:
38.42965
--> 2 rounds down to 0, so we keep just the $0.40
our answer is:
$38.40
Find the general solution to the following differential equation x^3•y’- y = 0
Answer:
y(x) = c_1 e^(-1/(2 x^2))
Step-by-step explanation:
Solve the separable equation x^3 (dy(x))/(dx) - y(x) = 0:
Solve for (dy(x))/(dx):
(dy(x))/(dx) = y(x)/x^3
Divide both sides by y(x):
((dy(x))/(dx))/y(x) = 1/x^3
Integrate both sides with respect to x:
integral((dy(x))/(dx))/y(x) dx = integral1/x^3 dx
Evaluate the integrals:
log(y(x)) = -1/(2 x^2) + c_1, where c_1 is an arbitrary constant.
Solve for y(x):
y(x) = e^(-1/(2 x^2) + c_1)
Simplify the arbitrary constants:
Answer: y(x) = c_1 e^(-1/(2 x^2))

Consider the line y= −2/9x-7. Find the equation of the line that is perpendicular to this line and passes through the point , (2, 3) Find the equation of the line that is parallel to this line and passes through the point , (2,3).
keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above
[tex]y=\stackrel{\stackrel{m}{\downarrow }}{-\cfrac{2}{9}} x-7\qquad \impliedby \qquad \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]
so then we can say that
[tex]\stackrel{~\hspace{5em}\textit{perpendicular lines have \underline{negative reciprocal} slopes}~\hspace{5em}} {\stackrel{slope}{-\cfrac{2}{9}} ~\hfill \stackrel{reciprocal}{-\cfrac{9}{2}} ~\hfill \stackrel{negative~reciprocal}{-\left( -\cfrac{9}{2} \right)\implies \cfrac{9}{2}}}[/tex]
so we're really looking for the equation of a line whos slope is 9/2 and passes through (2 , 3)
[tex](\stackrel{x_1}{2}~,~\stackrel{y_1}{3})\qquad \qquad \stackrel{slope}{m}\implies \cfrac{9}{2} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{3}=\stackrel{m}{\cfrac{9}{2}}(x-\stackrel{x_1}{2}) \\\\\\ y-3=\cfrac{9}{2}x-9\implies \boxed{y=\cfrac{9}{2}x-6}[/tex]
now as far as the parallel line
keeping in mind that parallel lines have exactly the same slope, so we're really looking for the equation of a line whose slope is -2/9 and passes through (2 , 3)
[tex](\stackrel{x_1}{2}~,~\stackrel{y_1}{3})\qquad \qquad \stackrel{slope}{m}\implies -\cfrac{2}{9} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{3}=\stackrel{m}{-\cfrac{2}{9}}(x-\stackrel{x_1}{2}) \\\\\\ y-3=-\cfrac{2}{9}x+\cfrac{4}{9}\implies y=-\cfrac{2}{9}x+\cfrac{4}{9}+3\implies \boxed{y=-\cfrac{2}{9}x+\cfrac{31}{9}}[/tex]

Prove the Pythagorean Theorem using similar triangles.
The sum of two numbers is 30
and their quotient is 2
What are the two numbers?
Answer:
The numbers are 20 and 10.
Step-by-step explanation:
Let's say these teo numbers are x and y.
The sum of two numbers is 30
x + y = 30
Isolate y
y = 30 - x
Their quotient is 2
plug the newfound y value in the second equation.
x / y = 2
[tex]\frac{x}{30-x} = 2[/tex]
multiply both sides by (30 - x) to get rid of the fraction.
x = 2(30 - x)
x = 60 - 2x
x + 2x = 60 + 2x
3x = 60
dividie both sides by 3
x = 20
find y
y = 30 - x
y = 30 - 20 = 10
y = 10
The numbers are 20 and 10.
Answer:
10 and 20.
Step-by-step explanation:
x + y = 30
x/y = 2
x = 2y so substituting in the first equation:
2y + y = 30
y = 10
and x + y =30
so x + 10 = 30 giving x = 20.

An angle measures 44° less than the measure of its supplementary angle. What is the
measure of each angle?
Answer:
The angle is 112 degrees and the supplement is 68 degrees.
Step-by-step explanation:
Let the angle’s measure be represented by x and the supplement’s measure be represented by y. Since supplementary angles add to 180 degrees, x + y = 180.
Since the supplement is 44 degrees less than the angle,
y + 44 = x
We can substitute y + 44 = x for x in the first equation, since they are equivalent.
y + 44 + y = 180
2y + 44 = 180
2y = 136
y = 68
Substitute 68 for y in one of the original equations and solve.
68 + 44 = x
x = 112

The area of a triangle is 142cm2. Two sides of the triangle measure 24cm and 38cm. What is the measure of the included angle between the side, approximated to 1 decimal place?
Answer:
C = 18.1°
Step-by-step explanation:
A = 142 m²
a = 24 cm, b = 38 cm
Use the formula A = a*b*sinC/2
142 = 24 * 38 * sinC/2 = 456*sinC
sinC = 0.3114
C = 18.1°

An angle measures 126° more than the measure of its supplementary angle. What is the measure of each angle?
Solution:
We know that:
A pair of supplementary angles always sum up to 180°This means that:
[tex]x + x + 126 = 180[/tex]Step-by step calculations:
Combine like terms and simplify:
[tex]x + x + 126 = 180[/tex]=> [tex](x + x) + 126 = 180[/tex]=> [tex]2x + 126 = 180[/tex]Subtract 126 both sides:
=> [tex]2x + 126 - 126 = 180 - 126[/tex]=> [tex]2x = 54[/tex]Divide 2 both sides:
=> [tex]\frac{2x}{2} = \frac{54}{2}[/tex]=> [tex]x = 27[/tex]This means that one angle is 27°. Let's find the other angle.
Finding the other angle:
[tex]27 + 126 = Other \space\ angle[/tex]=> [tex]153 \space\ = Other \space\ angle[/tex]Thus, the measure of the angles are 27° and 153°.
Answer:
27° and 153°
Step-by-step explanation:
Let "x" represent the angle.
We know that supplementary angles must add up to 180 degrees.
First, let's set up an expression for the supplement of the angle "x":
x+126
Now, let's use this information to set up an equation:
[tex]x+x+126=180[/tex]
Combine like terms:
[tex]2x+126=180[/tex]
Subtract 126 from both sides:
[tex]2x=54[/tex]
Divide both sides by 2
[tex]x=27[/tex]
The supplement would be:
[tex]x+126=27+126=153[/tex]
Therefore the measures of the two angles are:
27° and 153°

Which is greater 25% or 7/25
Answer:
7/25
Step-by-step explanation:
because its .28
The greatest between the 25% or [tex]\frac{7}{25}[/tex] should be considered as the [tex]\frac{7}{25}[/tex] because it is 28%.
Calculation of the greatest number:Since one percentage i.e. 25% and one fraction i.e. [tex]\frac{7}{25}[/tex]
We need to determine greater between these two
So the fraction in percentage could be 28%
So we can say that the fraction should be bigger.
hence, The greatest between the 25% or [tex]\frac{7}{25}[/tex] should be considered as the [tex]\frac{7}{25}[/tex] because it is 28%.

For a field trip, a bus company charges a flat fee plus an additional fee per student. For
40 students, the total cost is $170.00. If there are 45 students, the total cost is
$182.50. Write an equation that represents the total cost y of the field trip for x
students. What would the total cost be if 80 students went on the field trip?
Answer: here
Step-by-step explanation:
The answer comes from the derivation of a straight line model for the cost vs students. Note that the change in cost of 145-135.50 = 9.50 for an increase of students from 25 to 30. The ratio of change of cost to change of students = 9.50/5 = 1.9 and becomes the slope coefficient "m" in the formula y= mx + b. y = the total cost, mx becomes the variable cost and b becomes the fixed cost. To find b, use the data point given where the total cost = $135.50 when the students = 25, or 135.50 = 1.9*25 +b. Solving for b yields $ 88. Note that the other data point is where the total cost is $145 for students = 30. Using the new total cost equation shows that 30*1.9+88= 145 thus verifying the math model works for the data points provided.

The unknown number is x .
An equation to find the value of x :-
[tex]x + 5 = - 4[/tex]
Let us solve this equation :-
[tex]x + 5 = - 4[/tex]
[tex]x = - 4 - 5[/tex]
[tex]x = - 9[/tex]
The value of x is -9 . Let us place -9 in the place of x , to check whether or not we have found out the correct value of x .
So :-
[tex] - 9 + 5 = - 4[/tex]
[tex] - 4 = - 4[/tex]
[tex]LHS = RHS [/tex]
As the left hand side of the equation is equivalent to the right hand side of the equation, we can conclude that we have found out the correct value of x .
Therefore , -9 + 5 = -4 and ( x = -9 ) .
5+x=-4 is equation of sentence 5 more than a number x is -4 and -9 is the solution of equation.
