The nearest kilometers to 999.09344471 km is 1000 km.

Given value is 999.09344471 Km.

We have to calculate the round off value to the nearest kilometers. we know that after the decimal if the value of tenth place is 5 or bigger than 5 then we add 1 to the tens place digit, this is the fundamental rule of rounding off.

Now on following this rule from the very right hand side up to the tenth place digit we come to the conclusion that only  the value after the decimal (934) is to be rounded off which is (900).

So 999.09344471 km is finally becomes 999.900 km after rounding of to nearest hundredth value.

Again rounding off 999.900 km to nearest km so it becomes 1000 km.

The nearest kilometers to 999.09344471 km is 1000 km.

The total price of sneakers including tax will be equal to $20.75.

The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.

As per the given information in the question,

Price of sneakers = $20

Tax on sneakers = 3.75%

Then, the amount of tax will be,

(20 × 3.75)/100

= 75/100

= $0.75

Then, the total price of the sneakers will be,

$20 + $0.75

= $20.75

The Solution for the given system of equations is (-2) and \((\frac{5}{3})\).

The given are linear equations as follow:
y = \(\frac{2}{3}x\) + 3              .. ... ...(1)
and x  = -2.          .. .... ...(2)

We already know the first part of the solution (x) which is -2.  We can find the other part (y) by putting the value of equation (2) in equation (1).

By putting the values of x in equation (1), we get

y = \((\frac{2}{3})(-2)\) + 3
y = \(\frac{-4}{3}\) + 3

Taking the L. C. M of denominators which will be '3', we get:

y = \(\frac{-4 + 9}{3}\)

y = \(\frac{5}{3}\)

So the second part (y) of the solution of the given equation is \(\frac{5}{3}\).

Hence, the overall solution to the given system of equation is \((-2, \frac{5}{3})\).

The amount of the last payment that Elroy will make is $710, which includes the $200 monthly payment and a balance of $510.

The last payment amount is the result of the mathematical operations of subtraction and multiplication.

The first mathematical operation was the subtraction of the down payment from the total cost of the video game system.

Using multiplication, the monthly payments are determined to be $3,400 for 17 months.  This is subtracted from the remaining balance to obtain the last payment amount.

The cost of a custom video game/virtual sound system = $4,210

Down payment = $100

The remaining balance for monthly payment = $4,110 ($4,210 - $100)

Payment period = 18 months (1¹/₂ years)

Monthly payments = $200

Payment for the first 17 months = $3,400 (17 x 200)

Last payment = $710 ($4,110 - $3,400)

Thus, if Elroy makes the minimum monthly payment of $200 till the last payment, then he will pay $710 to settle the account.

The measure of angle ADM is 45.0°, as the intercepted arc AD is congruent to arc CD.

To find the measure of angle ADM, we need to consider that angle ADM is an inscribed angle and its measure is half the measure of the intercepted arc AD.

Given that the measure of arc CD equals the measure of arc DA, it means that these arcs are congruent.

Therefore, the intercepted arcs AD and CD have equal measures.

Since angle ADM is an inscribed angle intercepting arc AD, the measure of angle ADM is half the measure of arc AD.

Therefore, the measure of angle ADM is 45.0°, as the intercepted arc AD is congruent to arc CD.

Answer:

the composition results in \(\frac{23}{4}\)

Step-by-step explanation:

Assuming that what you typed for function g is correct (looks a bit peculiar, but we will use it as typed):

\(g(x)=-\frac{1}{-4x} +6\)

gof(-2) can be understood as: g(f(-2)), so what we need to do is to find the value for f(-2) using its given expression, and using then the obtained value as input for g(x):

\(f(x)=2x^2+2x-5\\f(-2)=2\,(-2)^2+2\,(-2)-5\\f(-2)= 8-4-5\\f(-2)= -1\)

So, we now evaluate g(-1):

\(g(x)=-\frac{1}{-4x} +6\\g(-1)= -\frac{1}{-4(-1)} +6\\g(-1)= -\frac{1}{4} +6\\g(-1)=\frac{23}{4}\)

According to given ratio, Dela will use 24 teaspoons of vinegar and 75 teaspoons of olive oil to make 6 containers of salad dressing.

What is ratio?

In mathematics, a ratio is a relationship between two or more numbers that indicates how many times one value contains or is contained within another.

Dela uses a ratio of 4 teaspoons of vinegar to 12.5 teaspoons of olive oil to make one container of salad dressing. To make 6 containers of salad dressing, she needs to multiply the amount of each ingredient by 6.

Thus, for 6 containers, she needs:

4 teaspoons of vinegar * 6 = 24 teaspoons of vinegar

12.5 teaspoons of olive oil * 6 = 75 teaspoons of olive oil

Therefore, the correct answer is: Dela will use 24 teaspoons of vinegar and 75 teaspoons of olive oil to make 6 containers of salad dressing.

The probability that the next person will purchase one or more costumes is approximately 0.27.

Given that:

44 visitors purchased no costumes.

14 visitors purchased exactly one costume.

2 visitors purchased more than one costume.

The sum of customers who bought exactly one costume and customers who bought several costumes represents the total number of visitors who made a purchase (one or more costumes):

⇒ 14 + 2

⇒ 16 visitors

The sum of visitors that didn't buy a costume bought one costume exactly, and bought many costumes equals the total number of visitors:

⇒ 44 + 14 + 2

⇒ 60 visitors

Therefore, the probability that the next person will purchase one or more costumes can be calculated as:

P = 16 / 60

P ≈ 0.27 (rounded to the nearest hundredth)

Answer:

the sample = the 100 times Sheldon brushed his teeth in front of the mirror

Step-by-step explanation:

In statistics, the sample is a small portion of a population that a researcher can study. It should represent a random subset of data from the population. The advantage of using a sample is that the size is smaller than the whole population, which makes it more manageable.

When you study the whole population, you are performing a census. That means that you are not obtaining a sample. In this case, the population would be every time that Sheldon or someone else washes his/he teeth in that bathroom.

To answer this question, we need to compare the ratios of miles traveled to gallons of gas used for car A and car B when they both use 1 gallon of gas.

For car A, we can see from the graph that 50 miles are traveled for every 2 gallons of gas used, or in other words, 25 miles are traveled for every 1 gallon of gas used. Therefore, car A can travel 25 times the distance for 1 gallon of gas.

For car B, we can see from the table that 40 miles are traveled for every 2 gallons of gas used, or in other words, 20 miles are traveled for every 1 gallon of gas used. Therefore, car B can travel 20 times the distance for 1 gallon of gas.

To compare the two ratios, we can divide the ratio of miles traveled to gallons of gas used for car A by the ratio for car B:

25/20 = 1.25

Therefore, car A can travel 1.25 times the distance car B can travel when both cars use 1 gallon of gas.

Ley "x" represents the amount of extra data used in one month.

"y" represents the monthly cost.

"m" represents the slope of the linear equation, which is the cost per extra GB.

"b" represents the constant of the linear equation, in this case, the cost of the data plan.

The line can be expressed as:

We know that the cost of the data plan is $25, this value represents the constant of the line (b)

Next, you have to determine the slope of the line.

The monthly cost after using 3GB (x) is $37 (y), this information corresponds to one ordered pair of the line (3,37)

The monthly cost after using 5GB (x) is $45 (y), this information corresponds to another ordered pair of the line (5,45)

Using both ordered pairs you can calculate the slope of the line with the formula:

Replace the coordinates and calculate the sloe:

The slope of the line is m=4, this means that the monthly cost of the plan increases $4 for every extra GB used.
