Show A is 90 minutes long, and Show B is 45 minutes long.
Let's say Show A is x minutes long. Then Show B is x/2 minutes long since Show A is twice as long as Show B. The total duration of Show A and Show B is 2 hours and 15 minutes, or 135 minutes.
So, x + x/2 = 135
Multiplying both sides by 2, we get 2x + x = 270
Combining like terms, we get 3x = 270
Dividing both sides by 3, we get x = 90
So Show A is 90 minutes long, and Show B is 45 minutes long.

what is a1 in a geometric series for which Sn=21825, an=125, r=15.
The a1 of the sequence is 28715.
How do you find the sum of geometric series?The sum of a geometric series can be found using the formula:
S = a / (1 - r)
where:
S is the sum of the series
a is the first term of the series
r is the common ratio, which is the ratio of any term to its preceding term
For a1;
Sn= a1 - anr/ r - 1
Where;
Sn = 21825
n = 125
r = 15
Thus;
2185 = a1 - (125 * 15)/15 -1
2185 * 14 = a1 - 1875
-30590 = a1 - 1875
a1 = 30590 + 1875

solve the system of equations below
Answer:
y = 2
Step-by-step explanation:
2x + y = 8 → (1)
x - 3y = - 3 → (2)
multiplying (1) by 3 and adding will eliminate y
6x + 3y = 24 → (3)
add (2) and (3) term by term to eliminate y
7x + 0 = 21
7x = 21 ( divide both sides by 7 )
x = 3
substitute x = 3 into either of the 2 equations and solve for y
substituting into (1)
2(3) + y = 8
6 + y = 8 ( subtract 6 from both sides )
y = 2
Answer:
y = 2
Step-by-step explanation:
The question has given us two equations with two unknown variables and told us to solve the system of equations.
To do this, there are multiple methods. The method used in this solution will involve taking any one of the variables and making it the subject of both equations and then equating the resulting equations.
Let's take the first equation:
[tex]2x + y = 8[/tex] ,
and rearrange it to make x the subject:
[tex]2x + y = 8[/tex]
⇒ [tex]2x = 8 - y[/tex] [Subtracting y from both sides]
⇒ [tex]x = \frac{8 - y}{2}[/tex] ------(i) [Dividing both sides by 2]
Now let's take the second equation and rearrange it to also make x its subject:
[tex]x - 3y = -3[/tex]
⇒ [tex]x = -3+3y[/tex] ------(ii) [Adding 3y to both sides]
As both equations (i) and (ii) are equal to [tex]x[/tex], we can say:
(i) = (ii)
⇒ [tex]\frac{8-y}{2} = -3+3y[/tex]
⇒ [tex]8 - y = 2(-3+3y)[/tex] [Multipying both sides by 2]
⇒ [tex]8-y = -6 +6y[/tex]
⇒ [tex]8 - y - 6y=-6[/tex] [Subtracting 6y from both sides]
⇒ [tex]8-7y=-6[/tex]
⇒ [tex]-7y = -6-8[/tex] [Subtracting 8 from both sides]
⇒ [tex]-7y = -14[/tex]
⇒ [tex]y = \frac{-14}{-7}[/tex] [Dividing both dies by -7]
⇒ [tex]y = \bf 2[/tex]
Therefore, the answer to the question is 2.
We can now easily calculate the value of x by substituting y = 2 into either equation (i) or (ii).
Substituting into (i):
[tex]2x + 2= 8[/tex]
⇒ [tex]2x = 6[/tex]
⇒ [tex]x = \bf 3[/tex]

The angles below are supplementary. What is the value of x? (5 points) A pair of supplementary angles is shown. One angle measures 3x + 40, and the other angle measures 80. a 16.6 b 20 c 26.7 d 40
Answer:
b) 20
Step-by-step explanation:
In supplementary angles, the sum of two angles add up to 180°
3x + 40 + 80 = 180
3x + 120 = 180
Subtract 120 from both sides,
3x = 180 - 120
3x = 60
Divide both sides by 3
x = 60 ÷ 3

Which values for x and y will satisfy both linear equations?
x = 0, y = 7
x = – 7, y = 0
x = 3, y = – 4
x = – 4, y = 3
Answer:
(-4,3)
x = -4 and y = 3
Step-by-step explanation:
Set the two equation equal to each other and solve for x.
x + 7 = [tex]\frac{3}{4}[/tex] x + 6 Multiply all the way through by 4 to clear the fraction
4(x + 7) = 4( [tex]\frac{3}{4}[/tex] x + 6) Distribute the 4
4x + 4(7) = 4([tex]\frac{3}{4}[/tex]x) + 4(6)
4x + 28 = 3x + 24 [tex]\frac{4}{1}[/tex] x [tex]\frac{3}{4}[/tex] = [tex]\frac{12}{4}[/tex] = 3 ([tex]\frac{4}{1}[/tex] is another name for 4) subtract 3x from both sides
4x - 3x + 28 = 3x - 3x + 24
x + 28 = 24 subtract 28 from both sides
x + 28 - 28 = 24 - 28
x = -4
Substitute -4 for x in either of the two original equations and solve for y.
y = x + 7
y = -4 + 7
y = 3
Check
Substitute in -4 for x and 3 for y and see if we get true statements.
y = x + 7

The show johnny want to binge is 61 episodes long, it takes him 5 hours to complete 12 episodes, and 10 hours to complete 24 episodes. If johnny were to watch 12 episodes a day, how many days would it take johnny to finish the show?
Answer:
6 days
Step-by-step explanation:
This is an easy problem if you think about it. Let’s start by identifying unnecessary information. I’ll go ahead and point this out: we don’t need to know how long it takes Johnny to watch the episodes. The question already says he’s only watching 12 episodes per day, so the time information is useless. If you rewrite the problem with only message information, you get something like this:
“The show Johnny wants to binge watch is 61 episodes long. If Johnny were to watch 12 episodes a day, how many days would it take him to finish the show?”
That makes it seem so much easier! Let’s start by dividing the show into sets of 12 episodes. 61 divided by 12 is 5 R1. Since he needs another day to finish the show, even if he only watches one episode, the answer is 6 days.

The population of a town increased by 1.5% per year from 1995 to 2015. The town's population at the beginning of 1995 was 16112. The 1-year growth factor for the town's population is 1.49%.
The population of a town increased by 1.5% per year from 1995 to 2015.
So, rate of growth is 1.5%.
The town's population at the beginning of 1995 was 16112.
So, initial population is 16112.
And we have to calculate 1 year growth factor.
So, we will use the formula i.e.
x(t) = [tex]x_{o}[/tex] × (1 + r) t
Here, Initially the Population is [tex]x_{o}[/tex] =16112
Growth Rate (%) (r) = 1.5
Number of years (t)= 1
So, we get=
x(t)=16112 × (1+1.5) 1
x(t)=16353.67
To calculate growth factor = (Final population- Initial population/ Initial population) *100
= (16353.67-16112/16112) *100

Karen borrowed $1000 from a friend that agreed to charge her a very low interest rate of .25% per month. The deal is that Karen will pay back $1100 at the time when the interest brings the total up to that amount. How many months will Karen have before the total reaches
$1100?
months (ROUNDED TO THE NEAREST MONTH)
Answer:
The interest amount Karen needs to pay each month is $1000 * .0025 = $2.5.
So, she needs to pay $1100 - $1000 = $100 in interest.
Therefore, Karen will have to pay for 100 / 2.5 = 40 months.
Rounding to the nearest month, Karen will have to pay for 40 months.

How do you find the least common denominator with variables?
Answer: To find the least common denominator (LCD) of fractions with variables, you need to determine the smallest number that all the denominators will divide into evenly.
One method to find the LCD is to multiply all the denominators together and simplify the expression. For example, if the denominators are x and y, the LCD would be xy. Another method is to find the greatest common factor (GCF) of all the denominators, and then divide each denominator by the GCF to obtain the LCD.
In either case, it may be necessary to factor the denominators to determine the GCF and simplify the expression for the LCD.

What is an equation?Two algebraic expressions having the same value and symbol '=' in between are called an equation.
Given:
Deselectric costs $11900 more than the Deswagon.
Unit cost:
Deselectric: $0.11 per mile.
Deswagon: $0.12 per mile.
Kweku drives about 18,000 miles a year.
That means
the cost for each car;
Deselectric: 18000 x 0.11 = $1980

A parallelogram has sides of 25 cm and 32 cm. If the distance between the longer sides is15 cm, find the distance between the shorter sides.
Step 1: Calculate the length of the diagonal. To calculate the length of the diagonal, use the Pythagorean Theorem: a2 + b2 = c2, where a is the length of one side and b is the length of the other side. In this case, a is 25 cm and b is 32 cm, so we have 252 + 322 = c2, which gives us c2 = 900 + 1024 = 1924. Taking the square root of this gives us c = 43.8 cm.
Step 2: Calculate the distance between the shorter sides. To calculate the distance between the shorter sides, subtract the length of the diagonal (43.8 cm) from the length of the longer side (32 cm), which gives us a total of 8.2 cm.
Therefore, the distance between the shorter sides is 8.2 cm.

587 Consider the equation y =2/3|x-5|-3. Complete the following without using a graphing
tool.
(a) What are the coordinates of the vertex of this graph?
(b) Find the coordinates of all axis intercepts of the graph.
(c) Sketch the graph by hand.
(d) Using each of these points and the vertex, compute the slope of each side of the graph.
How are these slopes related?
a) So x = 5 is the critical point, and the vertex is at (5, -3).
b) the y-intercept is (0, -3).
c) y = 2/3 * (x - 5) - 3 for x >= 5
y = -2/3 * (x - 5) - 3 for x < 5
d) The slopes of the two pieces are 2/3 and -2/3 respectively.
Step by step solution(a) To find the vertex, set the derivative of the equation to 0 and solve for x:
dy/dx = 2/3 * d/dx |x-5| = 2/3 * sign(x-5) = 0, where sign(x-5) = 1 if x > 5, sign(x-5) = -1 if x < 5, sign(x-5) = 0 if x = 5.
So x = 5 is the critical point, and the vertex is at (5, -3).
(b) The axis intercepts are the points where the graph crosses the x-axis and y-axis.
The x-intercepts occur when y = 0:
2/3 * |x-5| - 3 = 0
2/3 * |x-5| = 3
|x-5| = 9/2
x = 5 +/- 9/2 = 5 + 9/2 = 7 or x = 5 - 9/2 = 2.5
So the x-intercepts are (7, 0) and (2.5, 0).
The y-intercept occurs when x = 0:
y = 2/3 * |0-5| - 3 = -3.
So the y-intercept is (0, -3).
(c) The graph is a piecewise linear function with two pieces:
y = 2/3 * (x - 5) - 3 for x >= 5
y = -2/3 * (x - 5) - 3 for x < 5
(d) The slopes of the two pieces are 2/3 and -2/3 respectively. These slopes are related because the graph is symmetrical about the vertical line x = 5, with the two pieces being reflections of each other across the line.

Determine the center of the ellipse as well as the lengths of the major and minor axes:
5x2 +y2 −3x+40=0.
The center of the ellipse will be (3, 0). And the lengths of the major and minor axes will be 4.4721 and 2, respectively.
What is an ellipse?Ellipse is a locus of a point that moves in a plane such that the sum of its distances from the two points called foci adds up to a constant. It is taken from the cone by cutting it at an angle.
The equation of the ellipse is given below.
5x² + y² − 30x + 40 = 0
Convert the ellipse into standard form. Then we have
5x² + y² − 30x + 40 = 0
5[x² − 6x] + y² + 40 = 0
5[x² − 6x + 9] − 45 + y² + 40 = 0
5(x − 3)² + y² = 5
(x − 3)² + y² / 5 = 1
The equation center of the ellipse is (3, 0). Then the major axis is given as,
Major axis = 2 √5
Major axis = 4.4721
Then the minor axis is given as,
Minor axis = 2 x 1
Minor axis = 2
The center of the ellipse will be (3, 0). And the lengths of the major and minor axes will be 4.4721 and 2, respectively.
