Answer: 5 hours.
Step-by-step explanation: First you need to subtract the $12 fee from the total to find out how many hours he paid for. 57-12=45. So if he paid $45 at $9 per hour, 45 divided by 9 equals 5.
Simplifying Square Roots of Negative numbers
Answer:
10i
Step-by-step explanation:
using the fact that [tex]\sqrt{-1}[/tex] = i , then
[tex]\sqrt{-100}[/tex]
= [tex]\sqrt{100(-1)}[/tex]
= [tex]\sqrt{100}[/tex] × [tex]\sqrt{-1}[/tex]
= 10 × i
= 10i
= 0 + 10i ← in standard form
In the first week of July,1,020 a record people went to the local swimming pool. In the second week, 125 fewer people went to the pool than in the first week. In the third week, 145 more people went to the pool than in the second week. In the fourth week, 175 fewer people went to the pool than in the third week. What is the percent decrease in the number of people who went to the pool over these four weeks?
The percent decrease in the number of people who went to the pool over these four weeks is 15.2%.
How to calculate the percentage?The change regarding the people at the swimming pool for the number of weeks will be:
= 1020 - 125 + 145 - 175
= 865
The initial number of people is 1020.
Therefore, the percentage decrease will be:
= Decrease in number / Initial number × 100
= (1020 - 865) / 1020 × 100
= 155/1020 × 100
= 15.2%
The Percentage is 15.2%.

Express using exponents and simplify any numerical coefficients: w · w · w
Answer:
w to the power of 3 or w^3
Step-by-step explanation:
For example, plug in a number for the variable given, and in this case, I used the number 2. When using the number 2, the question would become 2 * 2 * 2. It would be simplified as 2 to the power of 2 to the power of 3. That's how I got the answer of w to the power of 3.
jack and bob leave their houses at 10:00 am walking toward each other. they meet at 10:30 am. if their houses are 7km apart, and jack is walking at 8 km/h , find bobs rate
URGENT
Bob is walking at the rate of 6 kilometer per hours
Jack and Bob leave their houses at 10:00 am walking toward each other and they meet at 10.30 am.
The distance between two houses = 7 kilometer
The speed of the Jack = 8 kilometer per hour
The distance traveled by Jack in 30 minutes = 8 / 2
= 4 kilometer
The remaining distance = 7 - 4
= 3 kilometer
Bob traveled 3 kilometers in 30 minutes
Then the speed of the Bob = 3 × 2
= 6 kilometer per hour
Hence, the Bob is walking at the rate of 6 kilometer per hours

The number of integers between 1 and 2022 inclusive that are multiples of 11 but not multiples of 3 is
The number of integers between 1 and 2022 inclusive that are multiples of 11 but not multiples of 3, using arithmetic sequences, is of:
122.
What is an arithmetic sequence?An arithmetic sequence is a sequence of values in which the difference between consecutive terms is constant and is called common difference d.
The nth term of an arithmetic sequence is given by the rule presented as follows:
[tex]a_n = a_1 + (n - 1)d[/tex]
In which [tex]a_1[/tex] is the first term of the arithmetic sequence.
The sequence composed by the integer multiples of 11 between 1 and 2022 are given as follows:
(11, 22, ..., 2013)
The first term and the common ratio of the sequence are given as follows:
[tex]a_1 = 11, d = 11[/tex]
The number of terms is obtained as follows:
2013 = 11 + 11(n - 1)
11n = 2013
n = 2013/11
n = 183.
The sequence composed by terms that are multiples of 11 and of 3 is given by:
(33, 66, ..., 2013).
The first term and the common ratio of the sequence are given as follows:
[tex]a_1 = 33, d = 33[/tex]
The number of terms is obtained as follows:
2013 = 33 + 33(n - 1)
33n = 2013
n = 2013/33
n = 61.
Hence the number of integers that are multiples of 11 but not 3 is given by:
183 - 61 = 122.

Nelson’s birthday party will be at the skating rink. The cost for each person is $ 25 . The cost of the room for the party is $ 50 . The function C ( x ) = 25 x + 50 models the total cost, C , where x is the number of people at the party. What is the maximum number of people who can be at the party for a budget of $ 600 ?
Answer:
24 people
Step-by-step explanation:
600 = 25x + 50 Subtract 50 from both sides of the equation
550 = 25x Divide both sides by 25
24 = x
Answer: x = 22
Step-by-step explanation:
We need to use trial and error for this.
20 - 25 seems like a reasonable range to substitute x with.
C(20) = 25(20) + 50
C(20) = 500 + 50
C(20) = 550.
This means that 20 is not the answer. Let's try 21.
C(21) = 25(21) + 50
C(21) = 525 + 50
C(21) = 575.
This means that 21 is also not the answer. let's try 22.
C(22) = 25(22) + 50
C(22) = 550 + 50
C(22) = 600.
This means that 22 is the maximum number of people for a budget of $600.

Answer:
4/3
Step-by-step explanation:
so in y=mx+b form.
m=slope b=y-int
Subtract 5 from both sides to isolate y on a side.
4x-6=3y
Divide both sides by 3 to isolate y on one side.
(4/3)x-2=y
y=(4/3)x-2
m=4/3
b=-2
So the slope is 4/3

What is a budget?A budget is an estimate of revenue and expenses for a given period of time that is usually compiled and re-evaluated on a regular basis. A budget expresses intended expenditures as well as recommendations for how to meet them with resources.
Saving is the portion of one's income that is not spent on current expenses. In other words, it is money set aside for future use rather than being spent immediately. An expense is a cost incurred by businesses in the course of their operations. Wages, salaries, maintenance, rent, and depreciation are expenses.

Quotient is 2x³ +x² -4x+3 for (2x⁴ – 3x³ – 6x² + 11x + 8) ÷ (x – 2)
What is Division?A division is a process of splitting a specific amount into equal parts.
(2x⁴ – 3x³ – 6x² + 11x + 8) ÷ (x – 2)
Let f(x)=2x⁴ – 3x³ – 6x² + 11x + 8
and g(x)=x-2
We need to divide the f(x) by g(x),
f(x)=g(x)× (2x³ +x² -4x+3)+16
If we equate the above equation with division algorithm which says,
a=bq+r
f(x)=g(x)q(x)+r(x)
so quotient is 2x³ +x² -4x+3
Hence quotient is 2x³ +x² -4x+3 for (2x⁴ – 3x³ – 6x² + 11x + 8) ÷ (x – 2)

Nachelle has a points card for a movie theater.
She receives 50 rewards points just for signing up.
She earns 12.5 points for each visit to the movie theater.
She needs at least 170 points for a free movie ticket.
Write and solve an inequality which can be used to determine vv, the number of visits Nachelle can make to earn her first free movie ticket.
Step-by-step explanation:
#=number
Identify what is in the inequalityNachelle gets 50 points when signing up: 50+#x=#
Nachelle earns 12.5 points for each visit: 50+12.5x=#
Nachelle need at least 170 points: 50+12.5x=170
Now you have your inequality, solve.Subtract 50 from both sides: 50-50+12.5x=170-50
50-50 cancel out so now your left with 12.5x=170-50
Subtract the 170 and 50: 12.5x=120
Divide 12.5 from both sides: 12.5x÷12.5=120÷12.5
12.5x÷12.5 cancel out so the inequality is now x=120÷12.5
Divide 120 and 12.5: x=9.6
Since there is no such thing as 9.6 visits, round to 10.

What number needs to be added to this set of numbers so the mean is 6? {3,4,7}
The finalized set is { 3 , 4 ,7 , 10 }
How is mean calculated ?Only numerical variables, whether continuous or discrete, can be used to calculate the mean. It is calculated by merely dividing the total number of values in a data set by the sum of all the values in the data set.
The given set is {3,4,7}
3 + 4 + 7 =14
To calculate the mean we divide the sum by the number of numbers present
So we must add 10
because if we add 10 to the set we get
3 + 4 + 7 + 10= 24
Thus the mean = [tex]\frac{24}{4}[/tex]
When we divide these two numbers we get :
mean = 6
Thus the finalized set is { 3 , 4 ,7 , 10 }
