A chemist measures the boiling point of a sample of benzene as 79.8 degrees Celsius. The actual boiling point is 80.1 degree Celsius. Round to the nearest hundredth of a percent, what is the percent error in the boiling point for the sample? Put the % sing after your numbers and do not put spaces in your answer.

Answers

Answer 1

Answer:

-0.375%

Step-by-step explanation:

Here, we want to calculate the percentage error

Mathematically;

% error = error/true value * 100%

error= the difference between the true value and the calculated

That is;

79.8-80.1 = -0.3

% error = -0.3/80.1 * 100%

% error = -0.375%

#2. Four times a number.

#3. A number divided by 14.

#4. A number minus 14.

Step-by-step explanation:

"the quotient" means to divide.
"the quotient of 14" means 14 is going to be divided by something. So we can write:

a polynomial contains number of terms​

Answers

Correct question is;

A polynomial contains _____ number of terms

Answer:

(n + 1)

Where n is the degree of the polynomial

Step-by-step explanation:

Now, for a polynomial that has degree of n = 1, the number of terms it will have is 2.

Similarly, a polynomial that has degree of n = 2, the number of terms it will have is 3.

This means from the above, we can deduce that the number of terms in a polynomial with degree "n" is n + 1.

We can therefore conclude that a polynomial can have any finite number of terms as n + 1

what is 6 divided by 1,932

Answers

Step-by-step explanation:

do u mean 1,932 divided by six?

Answer:

1932 divided by 6 in decimal = 322

1932 divided by 6 in fraction = 1932/6

1932 divided by 6 in percentage = 32200%

Step-by-step explanation:

The number 1932 is called the numerator or dividend, and the number 6 is called the denominator or divisor.

The quotient of 1932 and 6, the ratio of 1932 and 6, as well as the fraction of 1932 and 6 all mean (almost) the same:

1932 divided by 6, often written as 1932/6. 1932 divided by 6 = 322

The result of 1932/6 is an integer, which is a number that can be written without decimal places.

1932 divided by 6 in decimal = 322

1932 divided by 6 in fraction = 1932/6

1932 divided by 6 in percentage = 32200%

Which of the following do you use to tell whether a relationship is
proportional or not?

Answers

Answer:

The correct option to tell whether a relationship is proportional or not is;

[tex]\dfrac{y}{x}[/tex]

Step-by-step explanation:

A proportional relationship is a relationship between two variables, 'x', and 'y' such that they have equivalent ratio, such that all values of variable 'y' are given by the product of the values of the variable 'x' and a constant, 'k'

Therefore, y = k · x, from which we have;

[tex]\dfrac{y}{x} = k = Contant[/tex]

Therefore we can use [tex]\dfrac{y}{x}[/tex] to tell whether a relationship is proportional or not proportional.

What is the gradient f the line?"It is the ratio of the the change in the 'y' coordinate with respect to the change in the 'x' coordinate of that line.""It is used to calculate the steepness of a line."What is the slope-intercept form of the line?

"y = mx + c, where m is the slope and c is the y-intercept."

For given question,

We have been given an equation of the line L  y = 5x + 12

Comparing above equation with the slope-intercept form of the line,

we have m = 5 and c = 12

How much should a customer expect to pay for a one-night stay if they are a member of the hotel's loyalty club and make

Answers

Answer:

$114.32

Step-by-step explanation:

Original Price: $132.52

increased: $34.65

Loyalty Club: -$57.80

Phone Fee: $4.95

You add all of them together, except for the Loyalty Club Fee. You subtract that fee by the total.

The amount of pay for a one-night stay, if they are a member of the hotel's loyalty club and make their reservation over the phone, will be $113.77

What will be the amount?

The average cost of a one-night stay at a hotel was $132.52. Since then, the hotel has changed ownership, and several changes have been made to the cost of staying at the hotel. Last summer, the new owners adjusted room prices so that the average cost of a one-night stay increased by $34.65.

Last December, the new owners offered a $57.80 per night discount to guests who belong to their loyalty club. Last week, the new owners introduced a service fee of $4.95 for any reservation made over the phone.

The price will be calculated as:-

Original Price: $132.52

increased:   $34.65

Loyalty Club : - $57.80

Phone Fee: $4.95

You add all of them together, except for the Loyalty Club Fee. You subtract that fee by the total.

=  132.52  +   34.65   +   4.95   -   57.80  =  $113.77

Therefore the amount of pay for a one-night stay, if they are a member of the hotel's loyalty club and make their reservation over the phone, will be $113.77.
