A work shift for an employee at a restaurant consists of 8 hours. What fraction of the employee's work shift is represented by 6 hours? (Simplify your answer.)
Answers
Answer:
6 hours represents [tex]\frac{3}{4}[/tex] of the 8-h work shift.
Step-by-step explanation:
The fraction of the employee's work shift is equal to the given time divided by the work shift. That is:
[tex]x = \frac{6\,h}{8\,h}[/tex]
[tex]x = \frac{6}{8}[/tex]
[tex]x = \frac{3}{4}[/tex]
6 hours represents [tex]\frac{3}{4}[/tex] of the 8-h work shift.

There are four movies showing at the movie theatre. 2/3 of the people bought comedy, 1/4 bought tickets for horror movie, and 3/10 bought tickets for the kids movie what fraction represents the number of people who bought tickets for the action movie
Answers
Answer:
The fraction of people for 4th movie is 0.1167
Step-by-step explanation:
The number of people that bought a comedy movie ticket = 2/3
The number of people that bought the horror movie ticket = 1/4
The number of people that bought kids movie ticket = 3/10
Total number people for three movies = 2/3 + ¼ + 3/10 = 0.8833
The fraction of people for 4th movie = 1 – 0.8833 = 0.1167
Find the sum of first 20 terms of the arithmetic series in which 3rd term is 7 and 7th term is 2 more than three times its 3rd term.
Answers
Answer:
740
Step-by-step explanation:
Let the AP be a, a+d, a+2d, a+3d, ...
The term of AP is given by:
[tex]t n =a+(n-1)d[/tex]
We are given that the third term is 7.
[tex]t 3=7[/tex]
⇒ [tex]a+(3-1)d=7[/tex]
⇒[tex]a+2d=7 ---(1)[/tex]
Also, the seventh term is 2 more than three times the third term.
[tex]t7=3t3+2[/tex]
⇒[tex]a+ (7-1)d=3(a+(3-1)d)+2[/tex]
⇒[tex]a+6d=3(a+2d)+2[/tex]
⇒[tex]a+6d=3a+6d+2[/tex]
⇒[tex]-2a=2[/tex]
⇒[tex]a=-1[/tex]
We can put it in (1)
[tex]a+2d=7[/tex]
⇒[tex](-1)+2d=7[/tex]
⇒[tex]2d=8[/tex]
⇒d=4
Now, the Sum of n terms of an AP is given by the formula:
[tex]sn=\frac{n}{2}(2a+(n-1)d)[/tex]
So, Sum of first 20 terms would be:
[tex]s 20=\frac{20}{2}(2(-1) +(20-1) x 4)[/tex]
⇒[tex]s20=10(-2+19 x 4)[/tex]
⇒[tex]s 20=10 x(-2+76)[/tex]
⇒[tex]s 20= 10 x 74[/tex]
⇒[tex]s 20=740[/tex]
Thus, The Sum of first 20 terms of the AP is 740.

Jan is x years old, her sister is twice as old as her, and her brother is three times older than her. Their ages add up to 29. How old is each sister?
Answers
Jan's age = [tex] 4\frac{5}{6}[/tex] years
Sister's age =[tex] 9\frac{2}{3} \: years[/tex]
Step-by-step explanation:
Jan's age = x years
Sister's age = 2x years
Brother's age = 3x years
According to the given condition:
x + 2x + 3x = 29
6x = 29
x = 29/6
x = [tex] 4\frac{5}{6}[/tex] years
2x = [tex] 2\times \frac{29}{6}= \frac{29}{3}=9\frac{2}{3} \: years[/tex]
Therefore,
Jan's age = [tex] 4\frac{5}{6}[/tex] years
Sister's age =[tex] 9\frac{2}{3} \: years[/tex]

A right cylinder-shaped water ta is used to supply water to a reservoir. If the cylinder has a diameter of 16 feet and a height of 22 feet, what is a reasonable estimate of the maximum amount og water the tank can hold
Answers
Answer:
The tank can hold 4423.36 feet³ of water.
Step-by-step explanation:
Given that,
Height = 22 feet
Diameter = 16 feet
We need to calculate the maximum amount of water
Using formula of volume
[tex]V=\pi r^2h[/tex]
Where, h = height of cylinder
r = radius of cylinder
Put the value into the formula
[tex]V=\pi\times(8)^2\times 22[/tex]
[tex]V= 4423.36\ feet^3[/tex]
Hence, The tank can hold 4423.36 feet³ of water.
The graph of f(x) is the solid black graph below. Which function represents the
dotted graph?
4
6
y = f(2 + 1) + 4
y = f(x - 1) - 4
Submit Answer
y=f(x - 1) + 4
y = f(x + 1) - 4
Answers
The dotted graph moved down 4 so the answer had to have -4 and the graph moved to the left 1. What is inside the () causes the graph to move either left or right. Because it moved left 1 you add 1 to x. What’s inside the parenthesis is the opposite of what happens on the graph.( when the graph moves left you add and when it goes to the right you subtract)
Using translation concepts, it is found that the dotted graph is given by:
f(x - 1) - 4
------------------
For function f(x), the solid line, it has a zero at x = -1, while the dashed line has a zero at x = 0, which means that it was moved 1 unit to the right, thus f(x - 1).The dashed line is also below the function f(x), so 4 was subtracted, thus f(x - 1) - 4.A similar problem is given at https://brainly.com/question/18405655

if n represents the number:
5(n - 3) = 25

Write an expression to represent a circle's area in terms of its diameter, d .
Answers
Answer:
(d/2)^2 pi
Step-by-step explanation:
To find the area of a circle the formula is A=pi times radius sqaured. Since we do not have the radius we need to find it. The radius will always be half the diameter hence the (d/2). This will give us the radius, next is just to complete the area formula by squaring the radius and multiplying it by pi. i hope this helps :)
The circle's area, in function of it's diameter, is given by:
[tex]A = \frac{\pi d^2}{4}[/tex]
----------------------
The area of a circle, in function of it's radius r, is given by:[tex]A = \pi r^2[/tex]
The radius is half the diameter, thus: [tex]r = \frac{d}{2}[/tex]Replacing [tex]r = \frac{d}{2}[/tex] into the formula for the area, it is possible to find the area as a function of the diameter. Thus:[tex]A = \pi r^2[/tex]
[tex]A = \pi (\frac{d}{2})^2[/tex]
[tex]A = \pi \frac{d^2}{4}[/tex]
[tex]A = \frac{\pi d^2}{4}[/tex]
Which is the area of a circle of diameter d.

solve the following equation show your work 3{-x + (2x + 1)} = x - 1
Answers
Answer:
x = -2
Step-by-step explanation:
For this problem, we must simply solve for x. To do this, we will need equation operations, and the use of the distributive property.
Let's work this line by line until we have the value for x:
3{-x + (2x + 1)} = x - 1
3*-x + 3*(2x + 1) = x - 1
-3x + 6x + 3 = x - 1
3x + 3 = x - 1
2x = -4
x = -2
Now we can check our answer for x by plugging back into the original equation and see if the left hand side is equal to the right hand side:
3{-x + (2x + 1)} = x - 1
3{-(-2) + (2(-2) + 1)} ?= (-2) - 1
3{2 + (-4 + 1)} ?= -3
3{2 + (-3)} ?= -3
3{-1} ?= -3
-3 == -3
Thus, we have found the solution for x to be equivalent to negative 2.
Cheers.
Answer:
x = - 2Step-by-step explanation:
3{-x + (2x + 1)} = x - 1
First solve the terms in the bracket first
That's
3 (- x + 2x + 1 ) = x - 1
3( x + 1) = x - 1
Expand the terms in the bracket
We have
3x + 3 = x - 1
Simplify
3x - x = - 1 - 3
2x = - 4
Divide both sides by 2
We have the final answer as
x = - 2Hope this helps you

Directions:
Make the variable "y" all by itself. It need to be solo. For example for problem 34, negate 3 on each side and you will have "y=1/2(x+2)+3".
From there, plug in numbers into the x variable. (I suggest using common factors of "2" since the number your multiplying is 1/2.
Again using 34,
y=1/2(x+2)+3
y=1/2(2+2)+3
y=1/2(2+2)+3
y=1/2(4)+3
y=2+3
y=5
