Step-by-step explanation:

The product of 46 and 63 to the nearest ten is 3000

Product is the result of the multiplication process. Multiplication is the mathematical operation where a number a number is added to another number repeatedly. The sign that represents multiplication is x.

In order to round to the nearest ten, if the unit digit is greater than 5 or equal to 5, 1 is the added to the tens digit and the unit digit becomes zero. If the unit digit is less than 5, there is no change in the tens digit and the unit digit becomes zero.

46 to the nearest ten becomes 50

63  to the nearest ten becomes 60

50 x 60 = 3000

The product of  46 x 63 when it is been rounded off into the nearest ten can be written as 3,000.

Rounding off  can be described as the mathematical term of making a particular number to become simpler even though the value of that number is still intact .

From the question,  product of ( 46 x 63 )  will give us 3,818. however this number can be rounded off, to tens which will now give us 3,000 because it is tens the first two number from the right has been rounded off.

Therefore, option C is correct.

The estimate of the number of appetizers per guest is 20

The given parameters from the question are:

Number of appetizers = 212

Number of people invited = 12

From the question, we are to make use of compatible numbers

This means that we have the following approximation

Number of appetizers = 200

Number of people invited = 10

Next, we estimate the number of appetizers using

Number of appetizers = Total umber of appetizers/Number of people invited

Substitute the known values in the above equation, so, we have the following representation

Number of appetizers = 200/10

Evaluate

Number of appetizers = 20

Hence, the number of appetizers is 20

The solution of the given equation by rounding off it to the nearest ten-thousandth is 2.7182.

What is a round-off of the digit?

In mathematics, a round-off is defined as an approximation of the given number to a fewer number of significant digits by taking into consideration some rules.

For eg: 13.58 ~ 13.6

Solving the given equation: log x² = 2

We are given a logarithmic expression: log x² = 2        —- 1

We know that log x² = 2 log x and log (ab) = log a + log b

Using in equation 1, we have,

2 log x = 2

log x = 1

Using exponential on both sides, we have

e^(log x) = e^1

x = e

x = 2.7182

Hence, the solution of the given equation rounded off to the nearest ten-thousandth is 2.7182.

Time taken to fill an order of 2, 3, 4 dozen cookies are 45 minutes, 64 minutes and 89 minutes respectively.

To calculate time taken to fill the orders, we will add time used in different processes separately.

time taken to spoon =2 min for each dozen

time taken to bake =  10 min for each dozen

time taken to cool = 5 min for each dozen

time taken to pack = 2 min for each dozen

time taken to receive payment = 1 min for each dozen

time for cookies = mins to mix +  mins to spoon +  total baking mins +  mins to cool + mins to pack + min to receive payment

putting the values in the above formula, we get

Cycle time for 2 dozen cookies = 6 mins to mix + 4 mins to spoon + 20 total baking mins + 10 mins to cool + 4 mins to pack + 1 min to receive payment = 45 mins

Cycle time for 3 dozen cookies = 6 mins to mix + 6 mins to spoon + 30 total baking mins + 15 mins to cool + 6 mins to pack + 1 min to receive payment = 64 mins

Cycle time for 4 dozen cookies = 12 mins to mix + 8 mins to spoon + 40 total baking mins + 20 mins to cool + 8 mins to pack + 1 min to receive payment = 89 mins

Therefore, Time taken to fill an order of 2, 3, 4 dozen cookies are 45 minutes, 64 minutes and 89 minutes respectively.

The mass number of the atom is 4.

The mass number, also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus.

Therefore, the sum of protons and neutron in the nucleus of an atom is mass number of that atom.

Therefore, the atoms in the diagram has 2 electrons, 2 protons and 2 neutrons.

Notice the electrons revolving around the nucleus of an atom.

Therefore,

mass number = mass of neutron + mass of proton

mass number = 2 + 2

mass number = 4

The statement that the sales tax on a good that has been purchased is a function of the selling price in a given state, is TRUE.

The sales tax on an item that is purchased is calculated on the selling price of the item and then added to the item so that the person purchasing the item can pay for the sales tax as well.

Because the sales tax is based on the selling price, it is therefore a function of the selling price with the given state being the percentage of the sales tax.

For instance, a 4% sales tax on a good that is $10 is:

= 4% x 10

= $0.40

This sales tax is based on the selling price and so is a function of it.

After solving the equation, x = 15 is the value of x in 5-3x = -40 .

⇒ 5 - 3x = -40

⇒ - 3x = -40-5

⇒ - 3x =  -45

⇒ 3x = 45

⇒ x = 45/3

⇒ x = 15

To solve linear equations, utilize the steps that are provided below.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

⇒ 7z – 3z + 4 = 12

⇒ 4z = 12 – 4

⇒ 4z = 8

⇒ z = 8/4

⇒ z = 2

The value of equation P (x) = [tex]2[/tex] + [tex]\frac{x}{2}[/tex] + [tex]x^{2}[/tex] - [tex]\frac{x^{2} }{3}[/tex] when x = (-1) is P(-1) = [tex]\frac{13}{6}[/tex]

P (x) = [tex]2[/tex] + [tex]\frac{x}{2}[/tex] + [tex]x^{2}[/tex] - [tex]\frac{x^{2} }{3}[/tex]

If the value of x = -1

P (-1) = 2 + [tex]\frac{-1}{2}[/tex] + [tex](-1)^{2}[/tex] - [tex]\frac{(-1)^{2} }{3}[/tex]

P (-1) = 2 - [tex]\frac{1}{2}[/tex] + 1 - [tex]\frac{1}{3}[/tex]

The above equation consist of fractional numbers as well as the whole numbers to therefore it is not possible to apply the operations in this particular conditions.

On taking LCM for the denominators of the fractional numbers (2 , 3), we get 6 as the Least Common Multiple.

To apply the sum and difference operation, we need to make the denominators of all the terms same.

P (-1) = [tex]\frac{12}{6} - \frac{3}{6} + \frac{6}{6} - \frac{2}{6}[/tex]

P (-1) = [tex]\frac{12-3+6-2}{6}[/tex]
