3. The drama club sold 240 tickets to the play. They sold 20 more
student tickets than adult tickets. How many of each type of
ticket did they sell?
Answer:
100 adult tickets and 140 student tickets
Step-by-step explanation:
Answer:
Sold student tickets: 130, sold adult tickets: 110
Step-by-step explanation:
Let s = number of student tickets sold,
Let a = number of adult tickets sold.
[tex]s = 20+a[/tex] (It is given that there were 20 more student tickets sold than adult tickets)
[tex]s+a=240[/tex] (It is given that the total tickets sold is 240)
[tex]20+a+a = 240[/tex]
[tex]2a=220[/tex]
[tex]a = 110[/tex]
We can use substitution to find the number of student tickets:
[tex]s+a = 240[/tex]
[tex]s + 110 = 240[/tex]
[tex]s = 130[/tex]
∴110 adult tickets and 130 student tickets were sold.
I hope this helps :)
-64=(2cos(pi/2)+2i sin(pi/2))^n..... n=??
Answer:
The real solution is [tex]n=6[/tex].
Step-by-step explanation:
[tex]\cos(\frac{\pi}{2})=0[/tex] while [tex]\sin(\frac{\pi}{2})=1[/tex]
So the equation becomes:
[tex]-64=(2(0)+2i(1))^n[/tex]
[tex]-64=(0+2i)^n[/tex]
[tex]-64=(2i)^n[/tex]
We know that [tex]2^6=64[/tex]. So let's see what [tex]n=6[/tex] gives us:
[tex](2i)^6=64i^6=64i^4i^2=64(1)(-1)=-64[/tex].
[tex]-64[/tex] is the result we wanted.
[tex]n=6[/tex] is therefore a solution.
In the definition of rational numbers, b cannot equal 0, why?
Answer:
see explanation
Step-by-step explanation:
A rational number Q can be expressed in the form
[tex]\frac{a}{b}[/tex] where a and b can take any integer value except b = 0
This is because it would lead to division by zero which is undefined.
Question 21 (4 points)
What is the value of f(3) when f (C) = 4x + 1?
You may use Desmos to help you.
A
Answer:
Step-by-step explanation:
I take you mean that f(x) = 4x + 1. If it really is C leave a note below the question, and I'll come back if you post within the hour.
f(3) = 4*3 + 1
f(3) = 12 + 1
f(3) = 13

Ashlee worked 1,944 hours last year. She earned $14 for each hour she worked. She wants to use her earnings to buy a new vehicle. Vehicle Choices Price Sedan $25,750 Convertible $27,990 SUV $29,500 She said, "Since 2,000 × 14 = $28,000, and $27,990 is less than $28,000, I know I have earned enough to buy the convertible." Use the drop-down boxes to explain whether or not Ashlee's conclusion is logical.
Answer:
See Explanation
Step-by-step explanation:
The options are missing. However, the question is still solvable.
Given
[tex]Work\ Hours = 1944[/tex]
[tex]Earnings = \$14[/tex] per hour
[tex]Estimated\ Earnings = \$28,000[/tex]
[tex]Sedan = \$25,750[/tex]
[tex]Convertible = \$27,990[/tex]
[tex]SUV = \$29,500[/tex]
First, we need to calculate her actual earnings.
This is calculated by multiplying the actual work hours (without approximation) by the earnings per hour
[tex]Total\ Earnings = 1944 * \$14[/tex]
[tex]Total\ Earnings = \$27,216[/tex]
Next, we compare this actual earnings to the amount of a Convertible
[tex]\$27216 < \$27,990[/tex]
Hence, Ashlee's conclusion is not logical because with her actual earnings, she cannot afford a Convertible
So you want to finance a car for $4,840. Let’s say we offer you a 4.5% interest rate on a 2-year loan and 6% on a 5-year loan. Enter this info into the calculator to see your monthly and total cost by loan term.
Answer:
Totals: 4.5% = 435$ 6% = 1452$, Monthly: 18$, 24$
Step-by-step explanation:
1)Find the cost of fencing a rectangular park of length 175m and breadth 125m at the rate of 12/Rs per metre.
2)Find the cost of fencing a square park of side 250m at the rate of 20/Rs per metre.
Step-by-step explanation:
Length of rectangular park = 175 m
Breadth of rectangular park = 150 m
Perimeter of park = 2 x (length + breadth)
= 2 x (175 + 150)
= 2 x 325 = 650 m
Since, cost of fencing park per meter = = Rs. 12
Therefore, cost of fencing park of 600 m = 12 x 650 = Rs. 7,800
Square park=250m
Perimeter of the square park x 4
=250x4
=1000m
So, the cost of the fencing at the park would have a rate of 20 per m = 1000x20
=20000

Which statement correctly compares the function shown on this graph with the function y= 6x - 1? y 10 8 6 4 2 -10 8 6 4 2 -2 2 4 6 8 10 2 6
A. The function shown on the graph has a greater rate of change and a higher starting point. A
B. The function shown on the graph has a smaller rate of change and a lower starting point.
C. The function shown on the graph has a smaller rate of change, but a higher starting point.
D. The function shown on the graph has a greater rate of change and a lower starting point.
Answer:
B. The function shown on the graph has a smaller rate of change and a lower starting point.
Step-by-step explanation:
✍️The function y = 6x - 1, has:
slope (m) = 6, and
Starting point/y-intercept (b) = -1
✍️Let's find the slope (m) and the starting point (y-intercept) of the function shown on the graph:
Using the points, (0, -6) and (2, 4),
Slope = [tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{4 -(-6)}{2 - 0} = \frac{10}{2} = 5 [/tex]
Slope (m) = 5
The strating value is the value of y when x = 0. In order words, it is the point at which the line of the function intercepts the y-axis.
The y-axis is intercepted at y = -6.
Therefore, the starting value (b) = -6.
Therefore, the statement correctly compares the function shown on the graph above with the function y = 6x - 1 is:
B. The function shown on the graph has a smaller rate of change and a lower starting point.
Comparing their slopes, 5 is smaller than 6.
Comparing their starting points, -6 is lower than -1.

B

How do you get the range?
Answer: [-4, 8]
Step-by-step explanation:
The range is the mimimum y-value, the highest y-value.
On the graph, the lowest y-value is -4 and the highest y-value is 8. Thus, when writing in the range form, the range would by [-4, 8].
The range would be in hard brackets because the range touches exactly the points of -4 and 8. If each point had an open circle, instead of a closed point, there would be soft brackets.

What is the value of a?
Answer:
66
Step-by-step explanation:
The sum of all of the angles in a triangle is 180. So all three angles would add up to 180:
(a + 21) + 57 + (a - 30) = 180
Combine like terms:
2a + 48 = 180
2a = 132
a = 66
Answer:
a+21+57+a-30=180(angle of triangle)
2a+48=180
2a=180-48
2a=132
a=132/2
a=66
then,a+21=66+21 =87
a-30=66-30 =36

un terreno rectangular tiene 12 m. De frente y 40 m de fondo. ¿Cuál es el costo del terreno si el metro cuadrado cuesta $ 2100?
Responder: $ 352,800
Explicación paso a paso:
Paso uno:
La pregunta destinada a decir la dimensión de la parcela rectangular es 12 m de largo y 40 m de ancho - - - no 40 m de profundidad Primero, encontremos el área de la parcela rectangular
Área = L * W Área = 12 * 14
Superficie = 168m²
Segundo paso:
En segundo lugar, se nos dice que
1m² cuesta $ 2100 Por tanto,
168m² costarán x
Multiplicación cruzada que tenemos
X = 168 * 2100 X = $ 352,800
El costo del terreno es $ 352,800

Answer: 3 1/2
Step-by-step explanation: The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. Finally, simplify the fractions if needed. Therefore, a way to solve this problem is by multiplying (7/8 x 4/1) which will give us a final answer or result of 3.5 or 3 1/2.
Consider (cosine (StartFraction pi Over 2 EndFraction) = I sine (StartFraction pi Over 2 EndFraction) ) and z = 3 (cosine (StartFraction 3 pi Over 2 EndFraction) = I sine (StartFraction 3 pi Over 2 EndFraction) ).. What is w + z expressed in polar form?
The sum of given complex numbers in polar form as [tex]w+z=cos(\frac{\pi}{2} )+i~sin(\frac{\pi}{2} )[/tex]
What is complex number?"The number of the type a + ib is called as complex number, where a, b are real numbers and [tex]i=\sqrt{-1}[/tex] "
What is polar form of the complex number?"The polar form of a complex number z = x + iy is [tex]z=r(cos\theta+i~sin\theta)[/tex] where [tex]r=\sqrt{x^2+y^2}[/tex] and [tex]\theta=tan^{-1}({\frac{y}{x} })[/tex] "
For given question,
We have been given two complex numbers in polar form.
[tex]w=4(cos(\frac{\pi}{2} )+i~sin(\frac{\pi}{2} ))~,z=3(cos(\frac{3\pi}{2} )+i~sin(\frac{3\pi}{2} ))[/tex]
The sum of given complex numbers would be,
[tex]w+z= 4(cos(\frac{\pi}{2} )+i~sin(\frac{\pi}{2} ))+3(cos(\frac{3\pi}{2} )+i~sin(\frac{3\pi}{2} ))[/tex]
We know that
[tex]cos(\frac{\pi}{2} )=0\\\\sin(\frac{\pi}{2} )=1\\\\cos(\frac{3\pi}{2} )=0\\\\sin(\frac{\pi}{2} )=-1[/tex]
So, the sum of given complex numbers would be,
[tex]w+z\\\\= 4(cos(\frac{\pi}{2} )+i~sin(\frac{\pi}{2} ))+3(cos(\frac{3\pi}{2} )+i~sin(\frac{3\pi}{2} ))\\\\=4(0+i(1))+3(0+i(-1))\\\\=4(i)+3(-i)\\\\=i\\\\=0+i[/tex]
We can write above sum of complex numbers in polar form as,
[tex]0+i=cos(\frac{\pi}{2} )+i~sin(\frac{\pi}{2} )[/tex]
Therefore, the sum of given complex numbers in polar form as [tex]w+z=cos(\frac{\pi}{2} )+i~sin(\frac{\pi}{2} )[/tex]
