Answer:
x = 23
y = 157
Step-by-step explanation:
3x = x + 46 (outside angle of triangle theorem)
x + y = 180 (same side interior angles theorem)
<=>
2x = 46
x + y = 180
<=>
x = 23

2) How much 64% acid solution should be mixed with 12 gallons of a 38% acid solution in order to make a 52% acid solution?
Answer: 14 gallons of the 64% acid solution is needed
============================================================
Work Shown:
x = amount, in gallons, of the 64% acid solution
0.64x = amount of pure acid from the stuff we're adding in
0.38*12 = 4.56 = amount of pure acid from 38% solution
In total, we have 0.64x+4.56 gallons of pure acid out of x+12 gallons total
Dividing the two amounts will give us the decimal form of the percentage. Set this equal to 0.52 and solve for x
-----------
(0.64x+4.56)/(x+12) = 0.52
0.64x+4.56 = 0.52(x+12)
0.64x+4.56 = 0.52x+6.24
0.64x-0.52x = 6.24-4.56
0.12x = 1.68
x = 1.68/0.12
x = 14 gallons is the amount of the 64% acid solution we need to add in
Chose all the values of x that are not in the domain of this rational function. Picture attached, 15 points and I'll give Brainliest! Due in two hours. A. 5 B. -5 C. -2 D. 2
Answer:
Solution : Option A and Option C
Step-by-step explanation:
To find the values of x that are not present in the domain, we can start by making the denominator equal to 0. This would make the fraction undefined, and hence will solve for the value(s) of x that do not belong to the function -
x² - 3x - 10 = 0,
(x + 2)(x - 5) = 0,
x = - 2 and x = 5
Domain {x | x ≠ - 2 ≠ 5 }
Hence our solution(s) are option a and option c
Answer:
[tex]\huge \boxed{x=5 \ \mathrm{and} \ x=-2}[/tex]
Step-by-step explanation:
The domain of a function are all possible values for x.
To find the domain of a rational function, we set the denominator equal to 0, and solve for x. Those values of x are not included in the domain, since the denominator of 0 would make the rational function undefined.
[tex]x^2-3x-10 =0[/tex]
Factoring left side of the equation.
[tex](x+2)(x-5)=0[/tex]
Setting the factors equal to 0.
[tex]x+2=0 \\ \\ x=-2 \\ \\ \\ \\ x-5=0 \\ \\ x=5[/tex]
The values of x that are not in the domain of the rational function are x = -2 and x = 5.

Step-by-step explanation:
A function is a relation where each domain is assigned to exactly one range value.
In the relation given, the value of '-2' is repeated and assigned with two range numbers.
Therefore, the relation is not a function because -2 is paired with two range values.
Select the correct answer from each drop-down menu. The regular hexagon ABCDEF rotates 240º counterclockwise about its center to form hexagon A′B′C′D′E′F′. Point C′ of the image coincides with point of the preimage. Point D′ of the image coincides with point of the preimage.
Solution:
The point C' of the image coincides with point E of the preimage and D' of the image coincide with the point F of the preimage.
Explanation:
The regular hexagon have 6 corner points ABCDEF.
The complete angle about the center because it is a close figure as shown in given figure. It means the line from two consecutive vertices to the center of hexagon make an angle of because 6 lines from the vertices to the center divides the center angle in 6 equal parts.
It is given that the hexagon is rotated at counterclockwise about the center, therefore the image of vertices shifts 4 places counterclockwise.
In figure first hexagon show preimage and second hexgon shows image. From figure it is noticed that the point C' of the image coincides with point E of the preimage and D' of the image coincide with the point F of the preimage.
therefore, the point C' of the image coincides with point E of the preimage and D' of the image coincide with the point F of the preimage.

I AM ALWAYS HAPPY TO HELP :)Lucero dibujo las diagonales de un polígono regular y se dio cuenta que tiene que trazar 7 diagonales más que el numero de lados. ¿cuanto es la suma de ángulos internos de ese polígono?
Answer:
The sum of all internal angles of this polygon is: [tex]900^o[/tex]
Step-by-step explanation:
Recall that the formula for the number of diagonals of a polygon with n-sides is given by the formula:
[tex]diagonals=\frac{n\,(n-3)}{2}[/tex]
and since Lucero noticed that the number of digonals was 7 more that the number of sides, then, these two quantities (n + 7) and the number of diagonals must be equal. we can set an equation stating such, and solve for "n" (number of sides of the polygon):
[tex]n+7=\frac{n\,(n-3)}{2} \\2(n+7)=n(n-3)\\2\,n+14=n^2-3\,n\\n^2-3\,n-2\,n-14=0\\n^2-5\,n-14=0\\(n-7)\,(n+2)=0\\[/tex]
therefore n = 7 or n = -2
The only answer with meaning is the first one (7 sides), since a polygon must have a positive number of sides.
Now that we know the number of sides of the polygon, we can find what the sum of its internal angles should give, based on the equation;
Addition of internal angles of a polygon is = [tex](n-2)\,180^o[/tex]
Which in our case renders:
[tex](n-2)\,180^o=(7-2)\,180^o= 5\,(180^o) = 900^o[/tex]
a patio in the shape of a rectangle, is fenced on all sides with 134 feet of fencing. the patio is 5 feet less wide than its long. what is the area of the patio?
Answer:
The area of the patio is 1,116 ft^2
Step-by-step explanation:
Here in this question, we are interested in calculating the area of the patio.
Mathematically, area of patio is;
length * width
Unfortunately we do not have these values. Thus we need to get this from the value of the perimeter of the fencing and the relationship between the width and the length.
Mathematically, the total length of the fencing is the perimeter of the fencing.
Now, we are also told that the patio is 5 feet less wide than it is long.
So if the length is x ft, the width is (x-5) ft
Mathematically;
the perimeter of a rectangle is;
2(l + b)
Writing this in the x terms and equating to the perimeter, we have;
2( x + x -5) = 134
divide through by 2
2x -5 = 67
2x = 67 + 5
2x = 72
x = 72/2
x = 36 ft
Thus since the length is 36 ft, the width would be x -5 = 36 -5 = 31 ft
Done? No!
The question asks to calculate the area. Let’s move these values to the initial equation of the area in the start of the question.
Thus, we have 31 * 36 = 1,116 ft^2

If u^2-c^2=36 and u-c=6, what is u+c
Answer:
u + c = 6
Step-by-step explanation:
u² - c² ← is a difference of squares and factors as
u² - c² = (u - c)(u + c) = 36 , thus
6(u + c) = 36 ( divide both sides by 6 )
u + c = 6
(02.01)Polygon LMNP slides 5 units right and 4 units down on the coordinate plane. If the original measure of angle M was 50 degrees, what is the measure of angle M'? 40 degrees 45 degrees 50 degrees 130 degrees
Answer:
50°
Step-by-step explanation:
Transformation is the movement of one point from its initial location to a final location. If an object is transformed, all its points are transformed. Types of transformation is reflection, dilation, rotation and translation.
If an object is translated, it maintains its shape and size as well as the length of its sides and angles, only the location changes.
If polygon LMNP with ∠M of 50° is translated 5 units right and 4 units down to a new point, M' has the same angle measure. Hence ∠M' = 50°
Why use f(x) instead of y?
Answer:
The notation "f(x)" is exactly the same thing as "y"
Step-by-step explanation:
The effect of using f(x) instead of y is that it allows us to talk about f.
If we have an equation relating X to Y then that's a relationship between rwo nimbers.
For example if you have that y=
[tex]y = {x}^{3} [/tex]
...then that means that X and Y are some numbers obeying that equation

James just won the lottery for $30 million! He has two choices: first, he may receive $15 million today, or he may receive equal payments of $1 million a year for the next 30 years. Currently, the discount rate that he could invest the $15 million is 7% compounded annually. What should James do?
Answer:
The best option is the first one. It provides a higher present value.
Step-by-step explanation:
Giving the following information:
Option 1:
Receive $15,000,000 today.
Option 2:
Receive $1,000,000 for 30 years.
Discount rate= 7% compounded annually
To compare both options, we need to calculate the present value of Option 2. The option with the higher present value is the most convenient.
Option 2:
First, we need to determine future value:
FV= {A*[(1+i)^n-1]}/i
A= annual cash flow
FV= {1,000,000*[(1.07^30) - 1]} / 0.07
FV= $94,460,786.32
Now, the present value:
PV= FV/(1+i)^n
PV= 94,460,786.32 / (1.07^30)
PV= $12,409,041.18
The best option is the first one. It provides a higher present value.
