Unit rate is the quantity of an amount of something at a rate of one of another quantity.

3000 miles = 6 hours

4500 miles = 9 hours

The distance asteroid travel in 9 hours is 4500 miles

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

3000 miles = 6 hours

Divide both sides by 6.

500 miles = 1 hour

Multiply 9 on both sides.

9 x 500 miles = 9 hours

9 hours = 4500 miles

Thus,

The distance asteroid travel in 9 hours is 4500 miles

Step-by-step explanation:

Answer:

d) -21

Step-by-step explanation:

Given problem,

→ -11 + |-5| - |-15|

Let's solve the given problem,

→ -11 + |-5| - |-15|

→ -11 + 5 - 15

→ -11 - 10 = -21

Hence, the answer is -21.

Answer:

D. −21

Step-by-step explanation:

The bars either side of an expression or a value are the absolute value symbol.  

"Absolute value" means how far a value is from zero.

Therefore, the absolute value of a number is its positive numerical value.

Given expression:

[tex]-11 + |-5| - |-15|[/tex]

Absolute values in the given expression:

Therefore:

[tex]\begin{aligned} \implies -11 + |-5| - |-15|&=-11+5-15\\&=-6-15\\&=-21 \end{aligned}[/tex]

I WILL USE SUM OF INTERIOR ANGLES OF A TRIANGLE TO GET x

[tex](2x + 11) + (4x - 5) + 90 = 180 \\ 2x + 4x + 11 - 5 + 90 = 180 \\ 6x + 96 = 180 \\ 6x = 180 - 96 \\ 6x = 84 \\ \frac{6x}{6} = \frac{84}{6} \\ x = 14[/tex]

The percentage increase in cost greater from 2009 is 14.79%

The average price of milk in 2009 = $3.11

The average of price of milk in 2011 = $3.57

The increase in price = The average of price of milk in 2011 - The average price of milk in 2009

Substitute the values in the equation

The increase in price = 3.57 - 3.11

= $0.46

The percentage increase = The increase in price / The average price of milk in 2009 × 100

Substitute the values in the equation

The percentage increase = ( 0.46 / 3.11 )×100

= 14.79%

Hence, the percentage increase in cost greater from 2009 is 14.79%

The equation for the nth term of the arithmetic sequence is  [tex]a_{n}[/tex] = 25 - 4n  

An arithmetic sequence or arithmetic progression is a series of numbers with a common difference. For example 1, 2, 3, 4... is an Arithmetic sequence with a common difference 1. In an Arithmetic sequence, the difference between every two consecutive terms will be equal.

The formula for the nth term of a sequence is given below

=> [tex]a_{n}[/tex] = a + (n-1)d

where a is the first term and d is a common difference.

Here we have

21, 17, 13 ... is the arithmetic sequence

Where first term a = 21

and common difference d = term2 - term1 = 17 - 21 = - 4  

As we know the nth term of AP, [tex]a_{n}[/tex] = a + (n-1)d  

=>  [tex]a_{n}[/tex] = 21 + (n-1)(-4)

=>  [tex]a_{n}[/tex] = 21 - 4n + 4

=>  [tex]a_{n}[/tex] = 25 - 4n

Therefore,

The equation for the nth term of the arithmetic sequence is  [tex]a_{n}[/tex] = 25 - 4n

The amount owed at the end of 1 year is $4120 and by the end of 2 years, $4243.60 when Tom borrows $4000 at an interest rate of 3% compounded each year.

The interest you earn on interest is known as compound interest. Simple math can be used to demonstrate this: if you have $100 and it earns 5% interest annually, you will have $105 at the end of the first year. You will end up with $110.25 at the end of the second year. In order to calculate compound interest, multiply the principal of the original loan by the annual interest rate multiplied by the number of compound periods minus one.

Here,

principle amount=$4000

rate of interest=3%

For first year,

A=P(1+r/n)^(nt)

A=4000(1+3/12)^12*1

A=$4,120.00

For first year,

A=P(1+r/n)^(nt)

A=4120(1+3/12)^12*1

A=$4,243.60

When Tom borrows $4000 at an interest rate of 3% compounded annually, the total amount due at the end of one year is $4120, and at the end of two years, it is $4243.60.

There is not any chance of getting negative number in answer.

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

f(x) = 5

Here, f(x) = 5 shows that whatever is the value of x the result value will be 5.

As, there is no variable x in the defined function and only having a constant 5 which is positive in nature.

So, whatever be the value of x is we will get 5  only.

Thus, there is not any chance of getting negative number in answer.

For example, f(1)= 5, f(3)= 5, f(-5)= 5

Answer:

El ciclista recorre en una hora:

18 kilómetros.

Step-by-step explanation:

1 hora = 60 minutos

1 minuto = 1/60 = 0.01667 horas

1 kilómetro = 1000 metros

300 metros = 300/1000 = 0.3 kilómetros

Entonces:

300 metros por minuto = 300metros/minuto

300 metros / minuto = 0.3kilómetros / 0.01667 horas

= 0.3/0.01667

= 18 kilómetros/hora

El ciclista recorre 18 kilómetros cada hora

The height of the tower that was supported with the wire is 132.29 feet.

The tower, the wire and the ground would form a right triangle. A right triangle is a polygon that has three sides. The longest side is the hypotenuse. The other two sides are the length and the base.

In this question, the wire is the hypotenuse, the tower is the length and the ground is the base. Pythagoras theorem would be used to determine the height of the tower.

The Pythagoras theorem: a² + b² = c²

where:

a = length

b = base

c = hypotenuse

a² + 150² = 200²

a² + 22,500 = 40,000

a² = 40,000 - 22,500

a² = 17,500

a = √17,500

a = 132.29 feet

The probability that the advertising firm chosen at random has less than $1 million in revenue is 0.56.

The probability that the advertising firm chosen at random has an income between $1 million and $20 million or over $20 million is 0.44.

The rule used is the rule of addition only.

Probability is used in statistics to calculate the likelihood that a random event would take place.  The likelihood that the random event occurs has a probability value that lies between 0 and 1.

The more likely it is that the event would occur, the closer the probability value would be to 1. The more unlikely it is that the event would not happen, the closer the probability value would be to 0.

The rules of addition is used to determine the probability that either of two events would occur.

Probability that the advertising firm chosen at random has less than $1 million in revenue = total number of firms that have a revenue that is less than 1 million / total number of firms surveyed

Probability that the advertising firm chosen at random has less than $1 million in revenue = 148 / 264 = 0.56

Probability that the advertising firm chosen at random has an income between $1 million and $20 million or over $20 million = (number of firms that have an income between $1 million and $20 million / total number of firms) + (number of firms that have an income over $20 million / total number of firms)

x = √(27/11) is the local minima of the function g(x) = x¹¹ - 3x⁹ +2

Given, a function g(x) = x¹¹ - 3x⁹ +2

we have to find the local minima using the second derivative test.

first we differentiate the function,

g(x) = x¹¹ - 3x⁹ +2

g'(x) = 11x^10 - 27x^8

Now, putting g'(x) = 0

11x^10 - 27x^8 = 0

x^8(11x² - 27) = 0

Now, x = 0 or x = √(27/11)

After again differentiating the function we get

x = √(27/11) as the local minima of the function.

Hence, x = √(27/11) is the local minima of the function g(x) = x¹¹ - 3x⁹ +2

The horizontal line passing through the point (2, -6) is y = -6 and the vertical line passing through the point (2, -6) is x = 2

We need to write equations for the horizontal and vertical lines passing through the point (2, -6)

For a vertical line the value of x will never change. This will be true for any value of y.

So, the equation for a vertical line passing through this point is:

x = 2

Similarly, for a horizontal line the value of y will never change. This is true for any value of x.

So, the equation for a horizontal line passing through this point is:

y = -6

Therefore, the horizontal line passing through the point (2, -6) is y = -6 and the vertical line passing through the point (2, -6) is x = 2

A  = 9 billion.

r= 3% per year

A  = A_0*e^rt

9 = 8*e^3t/100

9/8 = e^3t/100

Taking log_e both sides,

log_e 9/8 = log_e e^3t/100
