The rate of commission for a commission of $5040 on total sales of $180700 nearest to tenth percent will be 2.8 %.

What is commission rate ?

The commission rate is the percentage or fixed payment associated with a certain amount of sale.

It is given that , Myrtle Gould's total sales last month were of $180700. And the commission she got for the sales was $5040.

Here , the sale is above the criteria to get the commission which is $50000.

The rate of commission can be calculated as follows :

Rate of commission (R) = (5040 × 100)  / 180700

or

R = 504000 / 180700

or

R = 2.8 %

or

Rate of commission will be 2.8 %.

Therefore , the rate of commission nearest to tenth percent will be 2.8 %.

Answer:

4x + 1.9 = 22.2

22.2 - 4x = 1.9

Answer choice:  C & E.

Step-by-step explanation:

Glad to help.

put the unknown price of the four tire patches as x,

and for all, it should add up to $22.20 and you're to subtract $1.90.

Step-by-step explanation:

x = number of km bus from A drives until they meet.

y = number of km bus from B drives until they meet.

x/80 is the time for the bus from A to reach the meeting point.

x/70 is the time for the bus from B to reach the meeting point.

both times must be equal, as they start at the same time.

so,

x/80 = y/70

but then we also know that together they have traveled the full 52 km to meet.

so,

x + y = 52

x = 52 - y

with that we go into the first equation :

(52 - y)/80 = y/70

(52 - y)/8 = y/7

7×(52 - y)/8 = y

7×(52 - y) = 8y

364 - 7y = 8y

364 = 15y

y = 364/15 km = 24.26666666... km

x = 52 - y = (780-364)/15 = 416/15 = 27.73333333... km

they will meet after (using bus from B)

364/15 / 70/1 = 364/1050 hours

= 182/525 hours =

= 60×182/525 = 10920/525 minutes =

= 728/35 = 104/5 = 20.8 minutes =

= 20 minutes 60×8/10 seconds =

= 20 minutes 48 seconds

control (using bus from A) :

416/15 / 80/1 = 416/1200 hours =

= 26/75 hours =

= 60×26/75 = 1560/75 minutes =

= 104/5 = 20.8 minutes

I found it from somewhere

What the given equation m = ((C + 200y) - 8000))/12y represents is as follows;

m is the amount of each monthly payment

C is the cost of the car

y is the length of loan in years

(C + 200y) - 8000) is the total amount she will repay

12y is the number of payments that she will make

We know that the formula to get the compound interest is;

A = P(1 + r/100)ⁿ

Where;

A is Amount.

P is Principal

r is Rate of interest

n is time in years

Now, when we compare that to our formula given as;

m = ((C + 200y) - 8000))/12y

we can say that;

m is the amount of each monthly payment

C is the cost of the car

y is the length of loan in years

(C + 200y) - 8000) is the total amount she will repay

12y is the number of payments that she will make

By subtracting the taxes from the gross pay we can see that Carlos' net pay is $1,500.30

We know that the gross pay is $1,800, now we need to subtract the social security and taxes.

First, there is a 6.2% and 19% in taxes, adding that we get:

6.2% + 9% = 15.2%

Then we need to subtract a 15.2% of the gross pay, this will give:

P = $1,800*(1 - 15.2%/100%) =  $1,800*(0.848) = $1,526.40

And now we also need to subtract the Medicare, which is $26.10, it gives:

$1,526.40 - $26.10 = $1,500.30

Considering the greatest common divisor, you obtain:

The greatest common divisor is the largest number that exactly divides two or more numbers at the same time. That is, it is the largest number by which two or more numbers can be divided, resulting in a whole number.

A method to calculate the greatest common factor must follow the following steps:

To find the greatest number of gift bags the party planner can make, you find the greatest common divisor.

To do this, decompose the numbers 96, 36 and 24:

The common factors with the smallest exponent are: 2² and 3

So, the greatest common divisor between 96, 26 and 24 is calculated as: 2²×3= 4×3= 12

This means that the greatest number of gift bags that the party planner can make is 12.

To calculate the number of each item present in each bag, you divide the quantity of each item by the quantity of gift bags:

Finally, the number of each item present in each bag is 8 pencils, 3 erasers and 2 pencil toppers.

According to the empirical rule, there are a answers of the given statement.

According to the statement

We have to find that the answers of the given statement.

So, For this purpose, we know that the

The empirical rule is a statistical rule which states that for a normal distribution, almost all observed data will fall within three standard deviations (denoted by σ) of the mean or average (denoted by µ).

From the given information:

The mean of 340 grams and a standard deviation of 35 grams.

Then

a) About 68% of organs weight between:

According to the empirical rule:

68% of the information values lie within 1 variance of the mean

95% of the info values lie within 2 variance of the mean

99.7% of the information values lie within 3 variance of the mean

Thus, 68% of the information values consist the range: Mean - 1 variance to Mean + 1 variance.

Using the values of Mean and variance, we get:

Mean - 1 variance = 320 - 20 = 300 grams

Mean + 1 variance = 320 + 20 = 340 grams

This means 68% of the organs will weigh between 300 and 340 grams.

And

b) In order to search out what percentage of organs weight between the given range, we'd like to seek out what proportion far these values are from the mean.

Since, mean is 320 and 280 is 40 but mean, we will write:

280 = 320 - 40

280 = 320 - 2(2)

280 = 320 - 2 Standard Deviations

Similarly,

360 = 320 + 40

360 = 320 + 2 Standard Deviations

So, we've got to inform what percentage of values lie within 2 variance of the mean. in step with the empirical law, this amount is 95%.

So, 95% of the organs weigh between 280 grams and 360 grams.

And

c) From the previous part we all know that 95% of the organs weight between 280 grams and 360 grams.

It is on condition that the distribution is bell shaped. the full percentage under a bell shaped distribution is 100%. So so as to calculate what proportion percentage of values are below 280 and above 360, we'd like to subtract the proportion of values that are between 280 and 360 from 100% i.e.

Percentage valuable outside the range = 100% - Percentage of values inside the range

So,

Percentage of organs weighs but 280 grams or over 360 grams = 100 - Percentage of organs that weigh between 280 grams and 360 grams

Percentage of organs weighs but 280 grams or quite 360 grams = 100% - 95% = 5%

So, 5% of the organs weigh but 280 grams or over 360 grams.

And

D) 300 is 1 variance below the mean and 360 is 2 standard deviations above the mean.

Previously it's been established that, 68% of the info values lie within 1 variance of the mean i.e

From 1 variance below the mean to 1 variance above the mean, the share of values is 68%. Since the distribution is bell shaped and bell shaped distribution is symmetric about the mean, therefore the percentage of values below the mean and above the mean must be the identical.

So, from 68% of the information values that are within 1 variance from the mean, 1/2 them i.e. 34% are 1 variance below the mean and 34% are 1 variance above the mean. Thus, percentage of values from 300 to 320 is 34%

Likewise, data within 2 standard deviations of the mean is 95%. From this half the information i.e. 47.5% is 2 standard deviations below the mean and 47.5% is 2 standard deviations above the mean. Thus, percentage of values between 320 and 360 grams is 47.5%

So,The total percentage of values from 300 grams to 360 grams = 34% + 47.5% = 81.5%

Therefore, 81.5% of organs weigh between 300 grams and 360 grams.

In the figure, m ∠ 7 = 100 °. The measure of angle 8 is 80°

An angle is a figure in the Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by the two rays are in the plane where the rays are located. The meeting of the two planes also creates angles. We refer to these as the dihedral angles. The angle formed by the rays lying perpendicular to the two crossing curves at the point of junction is another property of the intersecting curves.

Angle can also refer to length of a rotation or an angle. This metric represents relationship between a circular arc's length and radius. The arc is centered at the vertex and defined by sides in the case of a geometric angle. When there is a rotation, the arc is defined by any other point and rotation's image, and it is centered at the rotation's center.

Given,

∠7 = 100°

According to the given figure,
