Step-by-step explanation:

The word "while" indicates two events ("I was studying" and "she was making dinner") happening at the same time.

Answer:

N = 5/6

Step-by-step explanation:

4/5 N= 2/3.  Find N (solve for N).  

Isolate N.  To do this, multiply both sides of the equation by (5/4):

(5/4)(4/5)N= (5/4)(2/3)

becomes N = 10/12, or N = 5/6.

Answer:

1. F(-5) = -9

2. F(-4) = -7

3. F(1) = 3

4. F(3) = 7

5. F(5) = 11

Step-by-step explanation:

For each problem, F(x) is replaced with x.

An example is F(-5) = 2x + 1 (your first question).

To solve this, you replace x with -5.

This creates F(-5) = 2(-5) +1

We just simplify by multiplying -5 by 2 and then adding 1.

-5 times 2 equals -10. -10 plus 1 equals -9.

Your final answer for this example problem would be F(-5) = -9.

This applies to all problems as such -- F(x) where x inside the parentheses replaces all x values in the equation.

Answer: 0.086x

Step-by-step explanation:

Since the trend line starts at the origin, there is no y-intercept. To calculate the slope, divide the change in y over change in x. Since one of our points is the origin, we can just divide the y value by the x value, or 1.38 by 16, to get 0.08625. Rounded to the nearest thousandth, we get a slope of 0.086.

Answer: 2 ounce

Step-by-step explanation:

Given

16 ounce of the box is shared by Sue and Bill

Sue has eaten [tex]\frac{5}{8}[/tex] of the box

Bill has eaten [tex]\frac{1}{4}[/tex] of the box

total cereal eaten by them is

[tex]\Rightarrow \dfrac{5}{8}+\dfrac{1}{4}=\dfrac{5}{8}+\dfrac{2}{8}\\\\\Rightarrow \dfrac{7}{8}[/tex]

So, they have eaten this much of the box. Amount left in the box is

[tex]\Rightarrow 1-\dfrac{7}{8}\\\\\Rightarrow \dfrac{1}{8}[/tex]

In ounce it is

[tex]\Rightarrow 16\times \dfrac{1}{8}\\\\\Rightarrow 2\ \text{ounce}[/tex]

Answer:

They won't both be rational but that's about it. If one is rational and the other is not then the result is certainly irrational. Subtracting two irrational numbers might produce a rational value but it might also not. Consider: a=1+2–√, b=2–√ and a=3–√, b=2–√.

Step-by-step explanation:

Answer:

Rational number minus irrational number will result in an irrational number respectively : 2 - √3 is an irrational number. And it's consequent results [ Addition ] will also result the same : Aslike : 2 + √3 is also an irrational number. If you dig deep into the question it is similar to the basic odd minus odd or even minus even.

Answer:

$6,139.1

Step-by-step explanation:

Using the compound interest formula;

A = P(1+r)^t

P is the amount invested

A is the amount = $10000

r is the rate = 5%

t is the time = 10years

10000 = P(1+0.05)^10

10000 = P(1.05)^10

10,000 = P(1.6289)

Swap

P(1.6289) = 10,000

P = 10,000/1.6289

P = 6,139.1

Hence I need to invest $6,139.1

Answer:

No

Step-by-step explanation:

If the sprinkler takes 20 seconds to cross the garden, and it crosses the garden 150 times, the total number of seconds it took can be calculated by multiplying 20 and 150. You get 3000 seconds, but you need to convert that to minutes to tell if it will take more or less than an hour. So divide 3000 by 60 (the number of seconds in 1 minute). Your answer is 50 minutes. And since 1 hour is 60 minutes, it doesn't take more than an hour to cross the garden 150 times.

The required, 50 minutes is less than 1 hour, so we can conclude that it does not take more than an hour for the sprinkler to cross the garden 150 times.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

If a sprinkler passes across a garden every 20 seconds, then it makes 60/20 = 3 passes per minute.

To find out how many minutes it takes for the sprinkler to cross the garden 150 times, we can divide the total number of passes by the number of passes per minute:

150 passes / 3 passes per minute = 50 minutes

So it takes 50 minutes for the sprinkler to cross the garden 150 times.

To see if this is more than an hour, we can convert 50 minutes to hours:

50 minutes / 60 minutes per hour = 0.83 hours

Since 0.83 hours is less than 1 hour, we can conclude that it does not take more than an hour for the sprinkler to cross the garden 150 times.

Answer:

Dimension of the enclosure is 56.56 ft * 14.14 ft

Step-by-step explanation:

Given -

Let us suppose that x is the length of steel fence and y is the length of one side of pine boards

We know that - xy = 800.

y = 800/x

Let us say that  C is the cost of fence

                = 3x + 6(2y) = 3x + 12y = 3x + 12(800/x)

C = 3x + 9600x-1, x > 0

C' = 3 - 9600x-2 = (3x2-9600)/x2

C' = 0 when 3x2 = 9600

                  x2 = 3200

                  x = √3200 ft ≈ 56.56 ft

So, the cost is minimized when x ≈ 56.56 ft and y = 800/x ≈ 14.14 ft

Step-by-step explanation:

The missing height is 5 units

Recall that (area of a parallelogram) = (length)(height) and that

(height) = (area) / length.

Here,

(height) = (35 units^2) / (7 units) = 5 units

The missing height is 5 units

Answer:

D. 0

Step-by-step explanation:

the slope of the line is negative reciprocal to the slope of the other line 1/3=> -3

(5 - 2)/(x - 1) = -3

=> 3/(x - 1) = -3

=> x - 1 = -1

=> x = 0

Answer:

hola!!thanks for the fact 81,300 from scientific notation

Answer:

Step-by-step explanation:

"The graph of f(x) is a horizontal compression of the graph of the parent function" is true; the graph will appear to be narrower than that of y = |x|.  I would prefer to state "the graph of f(x) exhibits vertical stretching of the original (parent) function graph."

The true statement about f(x) = -6|x + 5| - 2  is 'the graph of f(x) is a horizontal compression of the graph of the parent function.'

"It is the squeezing of the graph toward the y-axis."

For given question,

We have been given a function f(x) = -6(|x + 5|) - 2

The parent function of f(x) is the function g(x) = |x|

Consider the graph of both the functions as shown below.

From the figure we can observe that,

- The graph of f(x) is a horizontal compression of the graph of the parent function g(x).

- The graph of f(x) opens downward.

Therefore, the true statement about f(x) = -6(|x + 5|) - 2 is 'the graph of f(x) is a horizontal compression of the graph of the parent function.'

Answer:

2/8. or simplified= 1/4

Step-by-step explanation:

Responder:

A) 1 ano

Explicação passo a passo:

Tempo máximo de tela = 3 horas / dia

Número de anos entre 11 e 18 anos = 8 anos

Vamos calcular o número de tempo de tela em um ano:

Número de dias em um ano = 365

Horas de uso em um ano:

3 horas / dia * 365 dias = 1.095 horas

Horas de uso em 8 anos:

1.095 horas * 8 = 8.760 horas

Convertendo o número de horas em anos:

Número de horas em um ano:

24 horas * 365 dias = 8760 horas por ano

Anos de tempo na tela:

Número de horas em 8 anos / número de horas em um ano

8760/8760 = 1 ano

Answer:

-1

Step-by-step explanation:

1.)Reorder the terms:

7(8 + x) = 49

(8 * 7 + x * 7) = 49

(56 + 7x) = 49

2.)Solving

56 + 7x = 49

3.)Solving for variable 'x'.

4.)Move all terms containing x to the left, all other terms to the right.

5.)Add '-56' to each side of the equation.

56 + -56 + 7x = 49 + -56

6.)Combine like terms: 56 + -56 = 0

0 + 7x = 49 + -56

7x = 49 + -56

7.)Combine like terms: 49 + -56 = -7

7x = -7

8.)Divide each side by '7'.

x = -1

9.)Simplifying

x = -1
