The value of the inches of snow in 1 minute is 8.01 inches.

It should be noted that an expression is important to show the relationship between the variables.

In this case, the expression is given as:

s = 8 + 0.01x

where x = the number of minutes past noon.

s = inches of snow.

In this case, when x = 1, the value will be

s = 8 + 0.01x

s = 8 + 0.01(1)

s = 8.01

6025 were the votes recieved by her opponent.

A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. The ratio of oranges to the overall amount of fruit is 8:14, while the ratio of lemons to oranges is 6:8.

Divide the votes she received by the 6 parts of the ratio to find the value of one part of the ratio, that is

7230 ÷ 6 = 1205 ← value of 1 part of ratio

Her opponent received 5 parts, thus

votes received by opponent =  5× 1205 = 6,025

In order to factor an integer, we need to repeatedly divide it by the ascending sequence of primes (2, 3, 5...).

The number of times that each prime divides the original integer becomes its exponent in the final result.

In our example,

The equation that could be used to determine v, the number of visits Damian must make to earn a free movie ticket is 20 + 12.5v = 195

Based on the information, the following can be illustrated:

He receives 20 rewards points just for signing up.

He earns 12.5 points for each visit to the movie theater.

He needs 195 points for a free movie ticket.

The equation will be:

20 + (12.5 × v) = 195

The value of the function f (6) will be 32.

What is substitution method?

Find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

Given that;

The value of the function;

f (1) = 1

And, The function is;

f (n) = 2 f (n - 1)

Now, Find the value of the function f (6) as;

Since, The function is;

f (n) = 2 f (n - 1)

Substitute n = 2, we get;

f (n) = 2 f (n - 1)

f (2) = 2 f (2 - 1)

f (2) = 2 f (1)

f (2) = 2 x 1

f (2) = 2

And, Substitute n = 3, we get;

f (n) = 2 f (n - 1)

f (3) = 2 f (3 - 1)

f (3) = 2 f (2)

f (3) = 2 x 2

f (3) = 4

And, Substitute n = 4, we get;

f (n) = 2 f (n - 1)

f (4) = 2 f (4 - 1)

f (4) = 2 f (3)

f (4) = 2 x 4

f (4) = 8

And, Substitute n = 5, we get;

f (n) = 2 f (n - 1)

f (5) = 2 f (5 - 1)

f (5) = 2 f (4)

f (5) = 2 x 8

f (5) = 16

And, Substitute n = 6, we get;

f (n) = 2 f (n - 1)

f (6) = 2 f (6 - 1)

f (6) = 2 f (5)

f (6) = 2 x 16

f (6) = 32

4              43

6               57

(C) The function which represents the statement is y(x) = 7x + 15 where x is the number of weeks.

Anthony has $15 and wants to save $7 per week.

Let the number of weeks be x and the amount he saved be y.

Then, the function that represents the situation is:

y = 7x + 15

Therefore,

y(1) = 7(1) + 15 = 22

y(2) = 7(2) + 15 = 14 + 15 = 29

y(3) = 7(3) + 15 = 21 + 15 = 36

y(4) = 7(4) + 15 = 28 + 15 = 43

y(5) = 7(5) + 15 = 35 + 15 = 50

y(6) = 7(6) + 15 = 42 + 15 = 57

So, the table of values is:

By finding the x-intercepts of the two linear functions, we can see that the laptop can stay on for 5 hours and the tablet for 6 hours, so the tablet can stay on for longer.

We know that g(x) shows the percent of battery power on a laptop, and on the graph we can see that it becomes zero at x = 5 hours, so the laptop can stay on for 5 hours.

We also know that linear function f(x) shows the battery of a tablet, the function is:

f(x) = 0.75 - 0.125*x

The value will be zero when the tablet runs out of battery, so we can solve:

0 = 0.75 - 0.125*x

0.125*x = 0.75

x = 0.75/0.125= 6

So the tablet can stay on for 6 hours, we conclude that the tablet can stay on longer.

Kathlego, Tessa, and Zane all work two jobs to make ends meet due to the high cost of living.

The attorney and painter is Kathlego.

Tessa is a doctor and an engineer.

The educator and author is named Zane.

Given that,

Kathlego, Tessa, and Zane all work two jobs to make ends meet due to the high cost of living, however there are both work in the same field. Doctor, engineer, teacher, lawyer, painter, and writer are among the professions.

As soon as we realize that Zane "is not the doctor," we immediately rule off that possibility and move on to the other professions.

Given that "Zane beat Tessa and the painter at tennis," we can infer that Tessa and the painter are no longer together, which makes Kathlego the Painter.

We currently have.

Kathlego is an painter.

We can now go on to "The painter was engaged by the doctor to do the task." The fact that Zane is not the doctor and we know the painter is Kathlego gives us a huge hint. Tessa is therefore unquestionably a doctor.

We currently have:

A painter, Kathlego.

Tessa is a engineer.

We may now infer that the person is one and the same because we have "The teacher and the writer went fishing with Kathlego." We can rule out Kathlego and Tessa as the teacher and writer because they each have two jobs. Thus, we are left to assume that Zane is the instructor and author.

We currently have:

A painter, Kathlego.

Tessa is a engineer.

Both a writer and a teacher, Zane.

Consequently, the lawyer, Kathlego, is the last task left for us to complete.

Therefore,

The attorney and painter is Kathlego.

Tessa is a doctor and an engineer.

Answer:

Step-by-step explanation:

x=30 is false.

x=y is false.

x+z=90 is true.

x+y+z=180 is false.

Answer: x=30 TRUE, x=y FALSE, y+z=90 TRUE, x+y+z=180 FALSE

Step-by-step explanation:

X=30 is true because each side is 90 degrees, and we already are given two values, 20 and 40. So to find x you do

90-(20+40) or 90-60.

This equals 30.

X=Y is false because we just saw that x is 30 degrees, and y looks to be 45 degrees. [tex]30 \neq 45[/tex]

Y+Z=90 is true because each side of the line is equal to 90 degrees and since there are two values y and z, we can do:

90/2=45.

This means that both y and z are 45 degrees and 45+45 is 90.

X+Y+Z is false because we have all of the values of them and when we add all of them together:

30 + 45 + 45

we get 120.
