The mass number of the atom is 4.
How to find the mass number of an atom?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 product of 46 and 63 to the nearest ten is 3000
What is the product?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.

Since the cookie sheets can hold exactly 1 dozen cookies, bbcc will produce and sell cookies by the dozen. How much time will it take to fill an order of 2, 3, or 4 dozen cookies?
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.

if the diameter of a circle is 18 feet, which is closest to the circumference
If the diameter of the circle is 18 feet, the circumference of the circle is 56.55 feet.
The circumference of a circle or ellipse in geometry is its perimeter. That is, if the circle were opened up and straightened out to a line segment, the circumference would be the length of the arc.
The diameter of a circle is 18 feet.
D = 18 feet
Now, the radius of the circle is half the diameter of the circle.
Therefore,
Diameter = 2 × Radius
Radius = Diameter / 2
D = 2r
r = D / 2
r = 18 feet / 2
r = 9 feet
Now, the circumference of a circle is given as:
Circumference = π × diameter
Circumference = π × 2r
Circumference = 2πr
Circumference = 2 × π × 9 feet
Circumference = 2 × 3.14159 × 9
Circumference = 56.55 feet

How to solve an equation?To solve linear equations, utilize the steps that are provided below.
Remove parentheses from each side of the equation and combine similar terms to make it simpler.To separate the variable term on one side of the equation, use addition or subtraction.To find the variable, use division or multiplication.The common denominator can be multiplied by each side of the equation to eliminate fractions.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

How to estimate the number of appetizers?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

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.

The sales tax on a purchased item in a given state is a function of the selling price
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.
How does sales tax relate to the selling price?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

Carolyn and Gershon are competing to see who can raise the most money for cancer research. Carolyn’s parents gave her $100, and she raised $15 a day. Gershon’s parents gave him $50, and he raised $15 a day. If they continued at the same rate, who won the contest?
Carolyn will win the contest as the money raised by her is more than the money raised by Gershon.
We are given that:
For Carolyn:
Money given by parents = $ 100
Money she raises every day = $ 15
For Gershon:
Money given by parents = $ 50
Money he raises every day = $ 15
Let the number of days a contest lasts be x.
So, the equations for both will be:
For Carolyn:
100 + 15 x
For Gershon:
50 + 15 x
By comparing, we get that:
Money raised by Carolyn > Money raised by Gershon.
Therefore, we get that, Carolyn will win the contest as the money raised by her is more than the money raised by Gershon.
