The trace of water left on the floor is the circumference of 565.2 cm.

Water traces are seen on the floor from a wet bicycle tire.

The bicycle wheel makes three complete rotations before coming to a stop, circumference  and the tire has a radius of 30 cm.

The circle of the cycle is indicated by the water stain left on the floor.

Given the radius = 30 cm

So,

C = 2 × 3.14 × 30

C = 188.4

Given that a bicycle wheel turns three times before pausing to pick up a trace of water, the answer is,

3 x 188.4 = 565.2 cm

the floor has a 565.2 centimeter trace of water.

The equation of the line is y = -(1/3)x + 5,

The equation of a line is an algebraic form of representing the set of points, which together form a line in a coordinate system.

We have,

The line is perpendicular to y = 3x - 2 and passes through (3, 4).

The slope of the line and the slope of y = 3x - 2 is:

[tex]m_{1} m_{2}[/tex] = -1

Where [tex]m_{2}[/tex] = 3

[tex]m_{1}[/tex] = -1/3

The common rate of both expressions are equal, so the expressions 64,96 and 60,90 are proportional

The expressions are given as

64,96 and 60,90

Rewrite the expressions as

(x, y) = (64,96) and (60,90)

As a general rule

Proportional expressions have the same constant rate

The constant rate (r) of the expressions is then calculated as

r = y/x

For the expression (64, 96), we have the following computation

r = 96/64

Evaluate the quotient

So, we have

r = 1.5

Aqil have 88 stickers.

Let Ryan have x stickers initially. Then Aqil will have (352-x) stickers. Ryan lost 25% of his stickers i.e., x-(25% of x)

= x- 25x/100

= x-x/4

= 3x/4

After Ryan lost 25% of his stickers, the ratio of Ryan's stickers to Aqil's stickers was 9:4 i.e.,

3x/4 : (352-x) = 9 : 4

⇒ 3x/4/(352-x) = 9/4

⇒3x/4 x 4 = 9 x (352-x)

⇒3x = 3168-9x

⇒3x+9x = 3168

⇒12x = 3168

⇒x = 3168/12

⇒x = 264

∴ Ryan have 264 stickers of the total 352 stickers and Aqil will have (352-x) i.e., 88 stickers.

Hence, Aqil have 88 stickers out of the 352 stickers.

We can buy 9 programs after buying the laptop if we want to spend $ 500 at most on the laptop.

The cost of the laptop = $ 319

The maximum money we have = $ 500

Money left after purchasing the laptop will be calculated by using subtraction.

Money left = $ 500 - $ 319 = $ 181

Now, cost of each program = $ 20

The number of programs we can buy = $ 181 / $ 20

The number of programs we can buy = 9.05

That means 9 programs.

The linear equation in slope intercept form is y = -2x + 1

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

The table represents the given parameters

On the table, we have the following points

(x, y) = (0, 1) and (1, -1)

A linear equation is represented as

y = mx + c

Substitute (x, y) = (0, 1) and (1, -1) in y = mx + c

So, we have

1 = 0 * m + c

-1 = 1 * m + c

This gives

1 = c

-1 =m + c

Rewrite 1 = c as

c = 1

Substitute c = 1 in -1 =m + c

-1 =m + 1

Evaluate

m = -2

Substitute m = -2 and c = 1 in y = mx + c

y = -2x + 1

Taking into account the definition of probability, the probability for a customer to pick at least one item is 14/15.

Probability is the possibility that a phenomenon or an event will happen, given certain circumstances and it is expressed as a percentage.

The probability of any event A is defined as the ratio between the number of cases in which event A may or may not occur and the total number of possible cases. This is called Laplace's Law:

P(A)= number of favorable cases÷ total number of posible cases

The union of events, AUB, is the event formed by all the elements of A and B. That is, the event is verified when one of the two, A or B, or both occurs and it is read as "A or B".

The probability of the union of two compatible events is calculated as the sum of their probabilities subtracting the probability of their intersection:

P(A∪B)= P(A) + P(B) -P(A∩B)

where the intersection of events, A∩B, is the event formed by all the elements that are, at the same time, from A and B.

In first place, let's define the following events:

So you know:

In this case, considering the definition of union of events, the probability for a customer to pick at least one item is calculated as:

P(M∪F)= P(M) + P(F) -P(M∩F)

P(M∪F)= 17/30 + 5/6 -7/15

P(M∪F)= 14/15

Answer:

He would have $100 in his bank account from the information provided

Step-by-step explanation:

An expression for the combined total dollar amount he earned this month:

Total Earning = 15b + P(N - b)

where, b is the total hours worked as a tutor

P is the amount earned by Ryan per hour as a waiter

N is the total number of possible hours Ryan can work in a month

In this question,

Ryan works as a tutor for $15 an hour and as a waiter for $10 an hour. This month, he worked a combined total of 81 hours at his two jobs.

Let the number of hours Ryan works daily as a waiter be x

and the number of hours worked daily as a tutor be y

Ryan earns $15 per hour as tutor.

So, we get an expression for the daily earnings on tutoring = 15y

Let Ryan earns $P per hour as waiter.

so, we get an expression for the daily earning as a waiter = Px

The total possible hours Ryan can work in a month is dependent on conditions not specified.

Assuming 24 working days (6 days weekly for 4 weeks) in a month with maximum approved work hours of 12 hours daily, the total hours Ryan can work will equal 24 x 12 = 288 hours

This 288hrs is an estimate and can change based on applicable hours of work daily and number of working days in a month; it can also be represented as N

If b is the total hours Ryan worked as a tutor this month, the hours Ryan can work as a waiter in a month is equal to 288 - b

So, in a month, Ryan will earn 15b as a tutor and P(288-b) as a waiter or optionally P(N - b)

So, the combined dollar amount earned in a month is:

Total Earning = 15b + P(N - b)

A composite function exists as a function that depends on another function. The value for  (f⁰f)(0) = - 4/3

In mathematics, function composition exists as an operation ∘ that takes two functions f and g, and has a function h = g ∘ f such that h(x) = g. In this operation, the function g exists used to the result of applying the function f to x.

Function composition is a mathematical procedure where two functions, f, and g, are taken and a function, h = g ∘ f, is produced such that h(x) = g(f(x)). The function g exists used in this operation on the outcome of applying the function f to x.

Let the two functions be g(x) = 3x + 2 and f(x) = x - 2/3

Now, (f⁰f)(x) = f[f(x)]

f(x) = x - 2/3

(f⁰f)(x) = f( x - 2/3)

simplifying the above equation, we get

(f⁰f)(x) = (x - 2/3) - 2/3  

(f⁰f)(0) = - 2/3 - 2/3

(f⁰f)(0) = - 4/3

Therefore, the value of (f⁰f)(0) = - 4/3.
