Answers

Answer 1

Answer:

q = -20

Step-by-step explanation:

Answer 2

The solution of the equation will be negative 20. Then the number of solutions to the equation will be one.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The equation is given below.

7q – 20 = – 10q + 20 + 19q

Simplify the equation, then we have

7q – 20 = – 10q + 20 + 19q

– 19q + 10q + 7q = 20 + 20

– 2q = 40

q = 40 / (–2)

q = – 20

The solution of the equation will be negative 20. Then the number of solutions to the equation will be one.

During one month Andre used 785 gallons of water at his home. There are approximately 3.8 liters in 1 gallon.Which measurement is closest to the number of liters Andre used during this month?

Answers

The closest measurement to the number of liters Andre used during the month is 2,983 liters of water.

How is the measurement determined?

The measurement of the number of liters used is determined by multiplying the number of gallons of water by the approximate value of 1 gallon in liters.

Using one of the mathematical operations, multiplication, the conversion of the quantity of water from gallons to liters can be computed.

Data and Calculations:

The total number of gallons of water used = 785

Conversion of 1 gallon to liters = 3.8 liters per gallon

The total number of liters of water used = 2,983 (785 x 3.8)

Thus, the closest measurement to the number of liters Andre used during the month is 2,983 liters of water.

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

The sales tax on a purchased item in a given state is a function of the selling price

Answers

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

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

Answers

The expression log 5-k log 2 can be expressed as log (5/[tex]2^{k}[/tex]) in the form of single logarithm.

Given that the expression is log 5-k log 2.

We are required to find the expression as a single logarithm.

Division of logarithm says that log (m/n)=log m-log n.

The expression is log 5-k log 2.

log 5-k log 2=log 5-log [tex]2^{k}[/tex]    

(We have to write the power of 2 which is k because it is in front of 2)

=log (5/[tex]2^{k}[/tex])

The statement which describes Jalen's error is that: A. Jalen computed the ratio of change in x to change in y.

What is a graph?

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.

How to calculate the slope of a line?

Mathematically, the slope of any straight line can be calculated by using this formula;

[tex]Slope, m = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope, m = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

Slope, m = Δy/Δx

In this context, we can reasonably infer and logically deduce that the statement which describes Jalen's error is that Jalen computed the ratio of change in x to change in y i.e Δx/Δy, instead of Δy/Δx = (0 - 3)/(-4 - 2).

The algebraic expression that represents the expression "six less than the quotient of a number and two, increased by ten" is [(n/2) - 6] + 10 and its value is 14 when n is 20.

An algebraic expression is a number, variable, or the combination of both and operational symbols.

The expression "six less than the quotient of a number and two, increased by ten" can be written as:

[(n/2) - 6] + 10

where n is the number

Evaluate the expression by substituting the value of n.

[(n/2) - 6] + 10

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?

Answers

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.
