Divide 5 pages by 3 hours to fins how many pages he wrote in 1 hour:

5 pages /  3 hours = 1 2/3 pages per hour.

Multiply 1 2/3 pages per hour by total hours to find total pages.:

1 2/3 x 8 = 13 1/3 pages (13.33)

Answer:

y  = 1.00+0.10 x

Step-by-step explanation:

Given that a taxi has a minimum charge of 1 dollar upto 1/10 mile and adds 0.10 for every additional 1/10 mile.

If a person travels <=1/10 miles his charges are 1 dollar

If he travels >1/10 miles charges are 1 dollar +0.10(extra miles 1/10)

Let y be the charges and x be the no of 1/10 miles.

Then the equation for y in terms of x would be

y =1.00 +1/10(x)

y  = 1.00+0.10 x

Answer: D. Yes because it passes the vertical line test.

Step-by-step explanation

A function cannot have duplicate x-coordinates.

When given a table or a set of coordinates, if there is an x-coordinate that is paired with two different y-coordinates then it is not a function.

When given a graph, the simplest way to determine if it is a function is to use the vertical line test.  If you can draw a vertical line anywhere through the graph and it passes through two points, then it is not a function.

In the given graph, it passes the vertical line test so it IS a function.

C (third graph, the parabola); To find if it is a function or not draw a vertical line on the graph. If the vertical line could never intercept the figure more than once anywhere on the graph then it is a function.

From left to right of the pictures it's the 3rd photo. It's the 3rd photo because it passes the vertical line test witch means if a vertical line was drawn within the middle of the graph it would only pass through one line and not two. The other ones would pass through two lines instead of one. I hope this helped you!

ratio = 12 : 48 = 1 : 4 = [tex]\frac{1}{4}[/tex] as a fraction in simplest form

Answer: The correct option is (D) (5, -2).

Step-by-step explanation:  We are given to use the method of substitution to solve the following system of equations :

[tex]3x+7y=1~~~~~~~~~~~~~~~~~~~~~~~~~(i)\\\\y=x-7~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)[/tex]

Substituting the value of y from equation (ii) in equation (i), we get

[tex]3x+7y=1\\\\\Rightarrow 3x+7(x-7)=1\\\\\Rightarrow 3x+7x-49=1\\\\\Rightarrow 10x=50\\\\\Rightarrow x=\dfrac{50}{10}\\\\\Rightarrow x=5,[/tex]

and from equation (ii) again, we get

[tex]y=x-7=5-7=-2.[/tex]

Thus, the required solution is (x, y) = (5, -2).

Option (D) is CORRECT.

8. D) MSN is the correct answer

The perimeter of a rectangle is twice the sum of the dimensions:

[tex] 2p = 2(w+l) [/tex]

We know two of the three unkowns, so we can solve for w:

[tex] 78 = 2(w+34) \iff 78 = 2w+68 \iff 10=2w \iff w=5 [/tex]

[tex]i^{77}=i^{4\cdot19+1}=(i^4)^{19}\cdot i^1=1^{19}\cdot i= i[/tex]

i^77 = (i^4)^19 * i

= 1^19  * i

= 1 * i

= i

Answer is   i

      700a + 1200r = 1,000,000

700(1000) + 1200r = 1,000,000

700,000  + 1200r = 1,000,000

                    1200r = 300,000

                           r = [tex]\frac{300,000}{1200} = \frac{3000}{12} = 250[/tex]

Answer:

Step-by-step explanation:

Given a geometric sequence.

2, 6, 18, 54, …

We have to find the I and nth term.

A geometric sequence. is one where each term is multiplied by a constant value to get the next term.

In our sequence, we find the pattern as each term is multiplied by 3 to get successive terms.

Hence common ratio r = 3

First term = a = 2

For Geometric sequence nth term = a_n = ar^(n-1)

Hence we get a_1 = 2

and a_n =  2(3)^(n-1)

By substituting for n any natural number we can get that term.

The number 12079 could be said two ways in terms of hundreds, tens, and ones. It can be 'twelve thousand, seventy-nine' or 'one hundred and twenty hundred, seven tens and nine ones'

The number 12079 can be said in two different ways using hundred, tens and ones. First, you could say it as 'twelve thousand, seventy-nine.' This is because 12 is the thousands component (consisting of hundreds and thousands), and 79 is the ones and tens components. Secondly, you could say it as 'one hundred and twenty hundred, seven tens and nine ones'

Aurora used 4 gigabytes of data in September.

To determine how many gigabytes of data Aurora used in September, we need to subtract the fixed phone service charge from her total bill. The difference will represent the additional charges for the data usage. Let's say she used x gigabytes. The equation for her bill can be written as: 65 + 12x = 113. To solve for x, we can subtract 65 from both sides and then divide both sides by 12 to isolate x. Solving this equation, we find that x = 4. So, Aurora used 4 gigabytes of data in September.

Answer:

Domain is the set of all real numbers

Range is the set of all real numbers.

Step-by-step explanation:

Given a graph with curve which has y intercept -5, and x intercept 5.

The graph is  continuous at all points of x and y

We find that the graph is a straight line with positive slope of the form

x/5 +y/-5=1

Or x-y =5

The graph is defined for all values of x and y.

The domain is the set of values x can take  

In the graph horizontal axis is x axis.

Hence from the graph we see that x can take values from -infinity to + infinity

Hence domain is x = R

For range, we consider the values of y as per graph.

WE find that y is  taking values in the interval (-infinity, infinity)

Hence Range =R

The term 'domain' in mathematics refers to the complete set of possible values of the independent variable in a function. The 'range' on the other hand, represents the possible results of the function after an experiment or survey. These values are not always numerical but could be a set of words or phrases.

The domain of a function is the complete set of possible values of the independent variable. In the context of your question, it can be a list such as X = {English, Mathematics,...} representing all the majors offered at a university, or it can be a numerical set, for example Y = {0, 1, 2,...} representing the integers from zero up to the upper limit of classes. Even functions like Z where the domain includes any amount of money from zero upwards can exist.

Similarly, the range of a function is the set of all possible values that the function can take after the experiment is performed or the question is answered. For instance, if a function has a domain of hair color, its range would be the different hair colors like black, blond, gray, green, orange, etc. This shows that the domain and range of a function are not necessarily numerical.

The specific value x the function takes only becomes known after performing the experiment or survey. However, there might be certain values that are outside the domain of the function and as such, would not give a reliable prediction, just like 90 in the dataset from 65 to 75. Such an occurrence doesn't fall within the domain of the function and can't be accurately predicted.
