We have that the floor's dimensions are 15ft x 20ft and the height of the room is 10ft tall. This is

if we extended it we would have:

We want to find how many square foot Brett needs to cover. We just find the area of each side of the studio.

We find it just by multiplying both of its sides (they all are rectangles):

Wall 1

area = 10ft x 15 ft

area = 150 ft²

Wall 2

area = 10ft x 20 ft

area = 200 ft²

Wall 3

area = 10ft x 15 ft

area = 150 ft²

Wall 4

area = 10ft x 20 ft

area = 200 ft²

Floor

area = 15ft x 20 ft

area = 300 ft²

Ceiling

area = 15ft x 20 ft

area = 300 ft²

A condensed way....

TOTAL AREA

Now, we add all the areas found, this will be the total area Brett must cover:

Wall 1 + wall 2 + Wall 3 + Wall 4 + ceiling + floor = total area

150 ft² + 200 ft² + 150 ft² + 200 ft² + 300 ft² + 300 ft² = 1300 ft²

COST

Since the padding costs $2.50 per square foot, and there are 1300 square foot to cover. Brett will spend

$2.50 x 1300 = $3250

Answer: Brett spend on padding $3250

Answer

Option B is correct.

Angle ABC > Angle DBC

Explanation

Since it's been proven that

Angle ABC = Angle ABD + Angle DBC

Since Angle ABD > 0,

Angle ABC > Angle DBC is the part that completes the proof that

Angle ABC > Angle RST

Answer:

A

Step-by-step explanation:

we have 3/4 in / minute.

so, we divide this by 3/4 to get the time for 1 inch.

and then we multiply by 1/3 to get the time for 1/3 inch.

that combination, dividing by 3/4 and multiplying by 1/3, can be done in any sequence (commutative property of multiplication).

therefore, this can be expressed as 1/3 divided by 3/4. and A is the correct answer.

Answer: $9

By definition, an equation is a statement that two mathematical expressions are equal.

Equations always contain the equal sign "="

Out of the 4 expressions listed, number 2. does not contain the equal sign, which means that this expression is not an equation.

All other expressions contain the equal sign, they can be considered equations.

SOLUTION

Step1: write out the giving equation

Step2: Integrate both sides of the equation above

Then simplify by integrating both sides

since the initial value is 25,000, then

the Population function is

b). For the population to reach 50,000 the time will be

Multiply the equation by 3, we have

To solve this we rewrite the function as

Answer:  B) 46.67% approximately

=================================================

Work Shown:

A = it will be cloudy tomorrow

B = it will be rainy tomorrow

P(A) = 0.30

P(B) = 0.15

P(A and B) = 0.14

Apply the conditional probability formula.

P(B given A) = P(A and B)/P(A)

P(B given A) = 0.14/0.30

P(B given A) = 0.4667 approximately

P(B given A) = 46.67% approximately

Answer:

b)  About 46.67%.

Step-by-step explanation:

Let event A = being cloudy.

Let even B = being rainy.

Given probabilities:

Therefore:

Conditional Probability Formula

[tex]\sf P(B|A)=\dfrac{P(A \cap B)}{P(A)}[/tex]

The probability of being rainy given it is cloudy = P(B | A).

Substitute the given values into the formula:

[tex]\implies \sf P(B|A)=\dfrac{0.14}{0.3}=0.46666...=46.67\%\;(2\;d.p.)[/tex]

Therefore, the probability of it being rainy if you know it will be cloudy is about 46.67%.

The average rate of change can be calculated as the division of the output of the function on the interest interval by the size of the interval. To do that we have to find the value of "y" at the end of the interval and subtract it by the value of "y" at the beggining. This is shown as an expression below:

For this function the values of x are:

The values for y are:

Using these values we can calculate the average rate of change:

The average rate of change for this function is approximately -3 for the given interval. The correct answer is A.

A sequence is called arithmetic if the difference between two consecutives is a constant

In the first case we see a constant difference of 5

every two consecutives have difference of 5, for example 20-15, 30-25 and so on.

In the second case we see the division between two consecutives is a constant . That is called a GEOMETRIC sequence.

the constant in this case is 18/6 =3

lets return to the 1st case find the explicit

An = Ao +(n-1) d

An means the n term in the sucession

Ao means the first term

d means the constant

with that in mind we replace the values obtained

An= 5 + (n-1) •5

now for the recursive

a1= 5

An = An-1 + 5

Now lets go to the second part, the geometric sequence. Just is needed to replace the values in the ABOVE RIGHT formula

so then

An = A1 •(3)^(n-1)

An = 2• (3)^(n-1)

Pythagorean theorem

Given the word problem, we can deduce the following information:

The correlation coefficient r is equal to 0.755.

To determine the coefficient of determination and the coefficient of nondetermination, we use the formulas below:

Now, we first plug in r=0.755 to get the coefficient of determination:

Next, we get the coefficient of nondetermination:

Therefore, the answer is:

The coefficient of determination is 0.570 and the coefficient of nondetermination is 0.430

We have the next function that models the Australian GDP since 1960 :

Where t is the number of years since 1960.

a)If we are in the year 1960, it means t=0

Therefore:

b)Now, we need to find the Australia capita in 1963.

This means t=3

Therefore:

c) We need to find when the function is equal to 100,000.

Therefore we equal the function G(t)=100,000.

Then:

Solve for t:

Divide both sides by 1806:

Add Ln for each side:

Then:

Rounded to the nearest year:

Therefore: 1960 +110 = 2070

On 2070 the Austranlian GDP reaches 100,000 USD

As we can see in the graph, we can calculate the slope with the following equation:

Let's consider any ordered pair, as (x1,y1)=(1,7) and (x2,y2)=(5,8), replacing this in the equation will give us:

Answer: the slope is equal to 1/4.

Explanation:

The zero-factor property states that if ab=0, then either a = 0 or b = 0 (or both). A product of factors is zero if and only if one or more factors is zero.

From these options only B and D have factors, but B equals to 3. In D we have that (3x-2) = 0 or the other factor is zero (or both)

Answer:

The correct answer is option D

The x and y intercepts of the line is found as (12/5, 0) and (0, -4/3) respectively.

For the given question,

The equation of the line is 5x-9y=-12.

For the x intercept, Put y = 0.

5x-9×0=-12.

x = 12/5

x intercept = (12/5, 0)

For y intercept, put x = 0.

5×0-9y=-12

y = -12/9

y = -4/3

y intercept = (0, -4/3)

Thus, the x and y intercepts of the line is found as (12/5, 0) and (0, -4/3) respectively.

The segments cannot be set equal since the constant terms 15 is greater than two. The variable x remains like a constant term in both sides of the point B.  we say that 15x > 2x

In mathematics, the signs used inequality calculations are

Using the picture as evidence the mark represented by B is not the midpoint hence the equality sign will not be used here. The sign to be used is the inequality sign.

In addition, the constants 15 and 2 shows that 15 is greater than 2. and there is no other addition to the variable x to help check the effect of the greatness of 15

The type of variation that describes each relationship include the following:

An indirect variation simply refers to a type of proportional relationship in which a variable is inversely proportional to another variable. This ultimately implies that, an indirect variation represents two variables that are inversely proportional to each other, which means as one variable increases, the other variable decreases and vice-versa.

Direct variation refers to a type of proportional relationship in which a variable is directly proportional to another variable. This ultimately implies that, a direct variation represents two variables that are directly proportional to each other, which means as one variable increases, the other variable also increases and vice-versa.

Newton's Second Law, F=m.a, describes the relationship between an object's mass, a force acting on it, and the resulting acceleration, where: F is force, in Newtons m is mass, in kilograms a is acceleration, in meters per second squared A young boy and his tricycle have a combined mass of 30 kilograms. If the boy's sister gives him a push with a force of 60 Newtons, what is his acceleration? 1 2 meter per second squared 2 meters per second squared 30 meters per second squared 90 meters per second squared​

we have that

F=m*a
