A theater charges $8 for an adult ticket, and $6 for a children's ticket. On a certain day, a total of 255 tickets were sold for a total cost of $1,850. How many more children's tickets were sold than adult tickets?
A. guess, check and revise
B. use a formula
C. work backwards
D. look for a pattern
Answer:
B
Step-by-step explanation:
By making an equation where x = number of adult tickets and y = number of children tickets, we can get 2 equations:
8x + 6y = 1850
x + y = 255
then we solve the equation to get each of the amounts
Two factory plants are making tb panels. yesterday, plant a produced 18,000 panels. two percent of the panels from plant a and 6% of the panels from plant b were defective. how many panels did plant b produce, if the overall percentage of defective panels from the two plants was 3%?
Plant B produces 6000 panels.
Given that, Plant A produces 18,000 panels out of 2% are defective and 6% of the panels produced by Plant B are defective.
Defective percentage : It is the number of defects divided by the sample size, multiplied by 100. So, if one tool is defective out of a sample size of 1,000, your percent defective is 0.1 percent.
No. of Defective Panels from Plant A + No. of Defective Panels from Plant B = Total No. of Defective panels
Let No. of Panels produced from Plant A = A and No. of Panels produce from Plant B = B
2% of 18000 + 6% of B = 3% of (18000 + B)
360 + 0.06*B = 0.03( 18000 + B)
360 + 0.06* B = 540 + 0.03*B
0.06*B - 0.03B = 540-360
0.03*B = 180
3B = 18000
B = 6000
CHECK:
2% of 18000 + 6% of 6000 = 360+360 = 720 defectives
18000 + 6000 = 24000
720 out of 24000 = 720/24000 = 72/2400 = 3%
Hence, Plant A produces 18000 panels and 2% of them , or 360, are defective.
Plant B produces 6000 panels and 6% of them, or 360, are defective.

1.Find the compound interest on Rs25000 for 3 years at 10% per annum ,Compounded annually.
Plzz answer this question in step by step explanation.
Answer:
The compound interest is Rs8275
Step-by-step explanation:
The rule of the compound interest is A = P[tex](1+\frac{r}{n})^{nr}[/tex], where
A is the new amountP is the initial amountr is the interest rate in decimaln is the number of periodst is the timeThe interest I = A - P
∵ The amount of investment is Rs25000 for 3 years
∴ P = 25000
∴ t = 3
∵ The rate of interest is 10% per annum, compounded annually
∴ r = 10% = 10 ÷ 100 = 0.1
∴ n = 1 ⇒ compounded annually
→ Substitute these value in the 1st rule above to find the new amount
∵ A = 25000[tex](1+\frac{0.1}{1})^{1(3)}[/tex]
∴ A = 25000[tex](1.1)^{3}[/tex]
∴ A = Rs33275
→ Use the 2nd rule above to find the interest
∵ I = 33275 - 25000
∴ I = 8275
∴ The compound interest is Rs8275

The European Working Time Directive (EWTD) directs that staff should work no more than an average of 48 hours a week, over a 13-week period. You work from 9:00 - 18:45 with a 30 minutes lunch break for three days a week and from 10:30 - 21:00 two days a week with a 45 minutes break. You also work from 10:00 – 14:00 every second Sunday. Are your hours EWTD compliant?
Answer:
it is not EWTD compliant
Step-by-step explanation:
Given that :
Directive = maximum average working hours per week = 48 hours
Engagement :
9:00 - 18:45 = (9 hrs 45 mins) - 30 mins = 9hrs 15 mins
9 hrs 15 mins for 3 days = 27 hours 45 mins
10:30 - 21:00 = (10 hrs 30 mins) - 45 mins = 9 hrs 45 minutes
Sundays (10:00 - 14:00) = 4 hours
Total work hours per week :
2(9hrs 15 mins) + 3(9hrs 45 mins) + 4 hours =;
18 hrs 30 mins + 29 hrs 15 minutes + 4 hours
(18 + 29 + 4) + 45 minutes
51 hours 45 minutes.
51 hours 45 minutes > 48 hours ; a Hence, it is not EWTD compliant

Find the slope of the line satisfying the given conditions
a) through (-3,4) and (2,-8)
b) through (5,-3) and (1,-7)
Answer:
a) The slope of the line is [tex]-\frac{12}{5}[/tex]
b) The slope of the line is 1
Step-by-step explanation:
The rule of the slope of a line that passes through points (x1, y1) and (x2, y2) is m = [tex]\frac{y2-y1}{x2-x1}[/tex]
a)
∵ The line passes through points (-3, 4) and (2, -8)
∴ x1 = -3 and y1 = 4
∴ x2 = 2 and y2 = -8
→ Substitute them in the rule of the slope above to find it
∵ m = [tex]\frac{-8-4}{2--3}[/tex] = [tex]\frac{-12}{2+3}[/tex] = [tex]\frac{-12}{5}[/tex]
∴ m = [tex]-\frac{12}{5}[/tex]
∴ The slope of the line is [tex]-\frac{12}{5}[/tex]
b)
∵ The line passes through points (5, -3) and (1, -7)
∴ x1 = 5 and y1 = -3
∴ x2 = 1 and y2 = -7
→ Substitute them in the rule of the slope above to find it
∵ m = [tex]\frac{-7--3}{1-5}[/tex] = [tex]\frac{-7+3}{-4}[/tex] = [tex]\frac{-4}{-4}[/tex]
∴ m = 1
∴ The slope of the line is 1

A Ferris wheel at an amusement park is modeled by (x – 70)2 + (y – 77)2 = 5,184, where the measurements are in feet. A slingshot attraction is modeled by y = –4x2 + 40x + 50. Which attraction reaches a greater height, and what does it represent in terms of the context?
A. The slingshot reaches a greater height at 50 feet, which is the vertex of the parabola.
B. The Ferris wheel reaches a greater height at 184 feet, which is the highest point on the circle.
C. The Ferris wheel reaches a greater height at 149 feet, which is the highest point on the circle.
D. The slingshot reaches a greater height at 150 feet, which is the vertex of the parabola.
Answer:
D. The slingshot reaches a greater height at 150 feet, which is the vertex of the parabola.
Step-by-step explanation:
First let's examine the given equations
[tex]\displaystyle \rm\\(x -70)^2 + (y-77)^2 = 5184 ............. (1)\\y = -4x^2 + 40x + 50 ............... (2)[/tex]
Equation (1) is of the form of a standard equation for a circle
[tex]\displaystyle \rm (x-a)^2 + y-b)^2 = r^2\\\\[/tex]
where (a, b) is the center of the circle and r is the radius
Equation (2) is the standard equation of a parabola
y = ax² + bx + c where a, b and c are constant
So we know that the Ferris wheel motion is circular while the slingshot motion is parabolic
Let's compute the highest point at which the Ferris wheel reaches.
Given,
[tex]\displaystyle (x-70)^2 + (y-77)^2 = 5184[/tex]
We can see that r² = 5182 by comparing it to the circle equation[tex]\displaystyle x_v=-\dfrac{40}{2\left(-4\right)}[/tex]
Therefore r = √5184 = 72. The diameter = 144 which is the highest point vertically from the center of the circle
The highest point on the circle = 144 + 5= 149 m since there is a 5' gap between the Ferris wheel and the ground at the lowest point so that has to be taken into account
For the parabola the vertex is the highest point and its x-coordinate given by [tex]\displaystyle \dfrac{-b}{2a}[/tex] in the standard equation for a parabola
Comparing the given equation with the standard equation we see that a = -4, b = 40 and c= 50
Therefore [tex]x_v[/tex] the x-coordinate of the vertex:
[tex]\displaystyle x_v=-\dfrac{40}{2\left(-4\right)} = 5[/tex]
The y coordinate of the vertex can be found by plugging in this value into the parabolic equation
[tex]\displaystyle y_v=-4\cdot \:5^2+40\cdot \:5+50 = 150[/tex]
This being the vertical coordinate of vertex of the parabola, the highest point that the slingshot reaches is 150'
So correct answer is D

b. The circle's radius is approximately cm.
c. The circle's area is approximately cm2.
Answer:
1.) CIRCLE B
2.) 14 cm ; 7cm ; 154cm²
Step-by-step explanation:
Given that:
CIRCLE A:
Diameter (d) = 9cm
CIRCLE B:
Radius (r) = 5cm
Circumference of circle A:
Radius (r) = diameter / 2
C = 2 * pi * r = 2 * 3.14 * (9/2) = 28.26 cm
Circumference of Circle B:
C = 2 * pi * r = 2 * 3.14 * 5 = 31.4 cm
CIRCLE B has the larger Circumference.
2.) circle with Circumference (C) = 44cm
Diameter of circle ;
C = 2 * pi * (d/2)
44 = 2 * 3.14 * (d/2)
44 = 6.28d / 2
88 = 6.28d
d = 14.01 = 14.0 cm ( 1 decimal place)
B.) Circle's Radius
Radius = diameter / 2
Radius = 14.0 / 2 = 7 cm
C.) Area (A) of the circle :
A = pi * r^2
A = 3.14 * 7^2
A = 3.14 * 49
A = 153.86
A = 154 cm²
