74 hours, and 4 hours. What was your average shift length this
week, expressed as a decimal?
Answer:
The average would be 22.25
Step-by-step explanation:
Average = [tex]\frac{sum}{count }[/tex]
6+5+74+4= 89
there are four numbers
[tex]\frac{89}{4}[/tex]=22.25

A pipe 11/15 liters of tub in 22/45 minutes what is its flow rate in terms of liters per minute
Answer:
3/2 liters/minute
Step-by-step explanation:
Divide 11/15 liters by 22/45 minutes:
11
------
15
-----------
22
-----
45
This is equivalent to:
11 45
----- * ----- = 3/2 (liters/min)
15 22
The flow rate of the pipe is 3/2 (or 1.5) litres per minute.
To calculate the flow rate of the pipe, we divide the volume of water (in litres) by the time taken (in minutes).
Given:
Volume of water = 11/15 liters
Time taken = 22/45 minutes
Flow rate = Volume / Time
Flow rate = (11/15) liters / (22/45) minutes
To divide by a fraction, we multiply by its reciprocal:
Flow rate = (11/15) x (45/22) liters/minutes
Simplifying the expression:
Flow rate = 495/330 litres/minutes
The fraction can be simplified further by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 165 in this case:
Flow rate = (495/165) / (330/165) litres/minutes
Flow rate = 3/2 liters/minutes
Therefore, the flow rate of the pipe is 3/2 (or 1.5) litres per minute.

What is the value of x?
O4 units
O 5 units
O 8 units
O 10 units
Answer:5 units!
Step-by-step explanation:
.
The value of x will be 5 units for the sphere that has the volume of (500/3)π cubic units.
From the formula of the volume of sphere,
volume of sphere = 4/3 πr³
where, r is the radius
in our case,
volume = (500/3)π
radius = x
substituting the given values
(500/3)π = (4/3)π *x³
x³ = 125
x= 5 units
Therefore, the value of x will be 5 units.

Which of the following square root of the following number below? Check all that apply. 361
Answer:
strangely worded question....
[tex]361^{1/2} = \sqrt{361}[/tex]
Step-by-step explanation:
=========================================================
Explanation:
Notice how (19)^2 = 19*19 = 361
This shows that 19 is a square root of 361. We can say [tex]\sqrt{361} = \sqrt{19^2} = 19[/tex]
Similarly, (-19)^2 = (-19)*(-19) = 361. The two negatives cancel each other out. So that's why there are two solutions to [tex]x^2 = 361[/tex] which are x = 19 and x = -19.
So far that accounts for answer choices B and D.
-------------------------------------------
The other two answers are [tex]-361^{1/2}[/tex] and [tex]361^{1/2}[/tex] (choices C and F) because anything to the 1/2 power represents a square root.
[tex]x^{1/2} = \sqrt{x}[/tex]
anything to the 1/3 power is a cube root
[tex]x^{1/3} = \sqrt[3]{x}[/tex]
anything to the 1/4 power is a fourth root
[tex]x^{1/4} = \sqrt[4]{x}[/tex]
and so on.
-------------------------------------------
Side note: For choice C, the exponent is done first before we apply the negative. So technically we could say [tex]-1*(361)^{1/2}[/tex] for choice C to mean the same exact thing. If your teacher said [tex](-361)^{1/2}[/tex] then this would not be an answer because this results in a non-real number.

Step-by-step explanation:
Tara looks up hotel room prices for a holiday.
A hotel has a 25% off sale on its prices.
A VAT charge of 20% must be added on at the end of the transaction after any discount.
If the regular price of a room is £90 per night, how much will Tara pay for 4 nights?
Answer:
Tara has to pay £324 for 4 nights
Step-by-step explanation:
Regular price of a room per night
= £90
Regular price of a room for 4 nights
= 90*4
= £360
Price of a room for 4 nights after discount
= 75% (360)
= 75/100 * 360 = 75 * 3.6
= £270
Price of the room after charging VAT
= 270 + 20%(270)
= 270 + 20/100 * 270
= 270 + 2 * 27
= 270 + 54
= £324
a box of candy contains 0.6 of pounds of caramels and 3.6 pounds of coconut what precent of the contents of the box
Answer:
We know that the box has:
0.6lb of caramels
3.6lb of coconut.
Then the total mass of candy in the box is:
0.6lb + 3.6lb = 4.2lb
This is the 100% of the box.
Now, we can write this as:
4.2lb = 100%
For example, if we want to know which percentage is caramels, we write the equation:
0.6lb = X
We want to find the value of X
Then we have two equations:
0.6lb = X
4.2lb = 100%
Let's take the quotient of these two equations:
(0.6lb/4.2lb) = X/100%
Now we can solve this for X:
(0.6lb/4.2lb)*100% = X = 14.3%
the caramels represent the 14.3% of the wheight of the box.
And for the coconut candy, we have the relation:
3.6lb = Y
Now let's do the same again, we start with the two equations:
3.6lb = Y
4.2lb = 100%
Take the quotient:
(3.6lb/4.2lb) = Y/100%
Solve for Y:
(3.6lb/4.2lb)*100% = Y = 85.7%
Now we found the percentage that represent each type of candy in the box.

185/100 + 50% + 4%=?
Answer:
2.39
Step-by-step explanation:
Convert everything to a decimal.
To do that with a fraction divide the numerator by the denominator.
185 divided by 100 = 1.85
185/100 = 1.85
To convert a percent to a decimal divide the number by 100.
50 divided by 100 = 0.5
50/100 = 0.5
4 divided by 100 = 0.04
4/100 = 0.04
Now add:
1.85 + 0.5 + 0.04 = 2.39

Answer:
#1: (B, D, E)
#2: (D) f(q) = 2q + 3
#3: (C) 1
#4: (B) f(5) = -1
#5: (A) - 8
Step-by-step explanation:
Question 1:
The number inside the parentheses is the input value, or x coordinate, and the output value (the number on the right side of the equal sign) is the y coordinate.
Use basic graph plotting skills to see if the x coordinate has a y coordinate value that's ON the graph line.
Question 2:
The variable "q" is our independent variable, also known as our x variable if you used the y = mx + b formula.
To rewrite 6q = 3s - 9 into function notation, you would solve for variable "s" using basic algebra:
6q = 3s - 9
6q + 9 = 3s
2q + 3 = s
s = 2q + 3 or f(q) = 2q + 3
Question 3:
The number inside the parentheses, -2, is the input value, or the x coordinate. Looking at the table, you can see that when you input -2, you get an ouput of 1.
Question 4:
Use the same process as Question 1.
Question 5:
The number inside the parentheses, 5, is the input value, or the x coordinate. Looking at the table, you can see that when you input 5, you get an ouput of -8.

Answer:

2. (4l
3. (3)
4. (2)
5. (1)
Step-by-step explanation:
1.
g(0) = 0
g(-1) = 1
g(1) = 1
2.
since q is the independent variable s must be dependent on q and hence s must be equal to f(q)
6q = 3s - 9
3s = 6q + 9
s = 2q + 3
f(q) = 2q + 3
that is the last option

Answer:
f= h/G
Step-by-step explanation:
The question is asking you to solve for f, or derive an equation of f in terms of h and G. The simplest way to solve for f is to isolate it from other variables.
h=fG
Now divide both sides by G
h/G=f
And there you go you solved for f.
Type the correct answer in the box. If necessary, use / for the fraction bar. Marilyn has 10 caramels, 12 mints, and 14 bars of dark chocolate in a bag. She picks three items from the bag without replacement. The exact probability that Marilyn picks a mint, then another mint, and finally a bar of dark chocolate is
Answer: 77 / 1785
Step-by-step explanation:
Number of caramels = 10
Number of mints = 12
Number of dark chocolate = 14
Total number = 36
Since it's without replacement, the exact probability that Marilyn picks a mint, then another mint, and finally a bar of dark chocolate will be:
= 12/36 × 11/35 × 14/34
= 1/3 × 11/35 × 7/17

What is the slope of the line graphed on the coordinate plane?
A graph with a line running through coordinates (0, 6) and coordinates (1, -2)
Work Shown:
Apply the slope formula
m = (y2-y1)/(x2-x1)
m = (-2-6)/(1-0)
m = -8/1
m = -8
The slope is -8
We can think of it like saying "go down 8 and move to the right 1 unit", since -8 = -8/1.
Put another way: slope = rise/run = -8/1
rise = -8 and run = 1.
Answer:
-8
it's easy just use the equation y2-y1 ÷ x2-x1
