7 pencils in each holder

:]

Ryan will put 7 pencils in each pencil holder.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in "m" in different ways and if following it, a second event can occur in "n"  ways; then the two events in succession can occur in m × n  ways.

Given that Ryan has 21 pencils, wants to put the same number of pencils in each of the 3 pencil holders.

Pencil = 21

Pencil holder = 3

Therefore, we will do as 21 divided by 3

21/3 = 7

Hence, there are 7 pencils in each pencil holder.

The overall percentage increase of the cost of gasoline during the three-year period is 14.33%.

A percentage is a number or ratio expressed as a fraction of 100. It is generally denoted using the percent sign ''%''.

The given percentage are,

8%, 15%, and 20%.

Now to find the overall average increase we need to find the average percentage for three consecutive years.

overall average = sum of all the percentage/number of percentage

overall average =  8%+15%+ 20%/3

overall average =  43%/3

overall average =  14.33%

Hence,The overall percentage increase of the cost of gasoline during the three-year period is 14.33%.

Answer:

Step-by-step explanation:

The maximum number of voters that can vote republican and green is 44% and 4% respectively, and the minimum number of voters that can vote republican and green is 40% and 0% respectively.

Given that,
The circle graph shows the results of a survey of registered voters on the day of an election,
Other: 4%     Green: 2%     Libertarian: 5%      Democratic 47%      Republican: 42%         Error: 2%

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
The maximum percent of voters who could vote republican,
= 42%  + 2%
= 44%

The minimum percent of voters who could vote republican,
= 42% - 2%
= 40%

The maximum percent of voters who could vote green,
= 2% + 2%
= 4%

The minimum percent of voters who could vote green,
=2% - 2%
=0

Thus, the maximum number of voters that can vote republican and green is 44% and 4% respectively, and the minimu number of voters that can vote republican and green is 40% and 0% respectively.

Answer:

42 and 22 are the numbers

Step-by-step explanation:

Let the numbers be x and y

[tex]x + y = 64[/tex]

[tex]x - y = 20[/tex]

On adding both

[tex]x + y + x - y = 64 + 20[/tex]

[tex]2x = 84[/tex]

[tex]x = \dfrac{84}{2} [/tex]

[tex]x = 42[/tex]

Using 1

[tex]42 + y = 64[/tex]

[tex]y = 64 - 42[/tex]

[tex]y = 22[/tex]

Answer:

x = 5.5 inches.

x = 5.5.

Answer:

I believe the textbook is telling you which rounded version of pi () to use when solving questions regarding the geometry of circles. This is not a definite answer, as the question you asked is not completely clear cut. It is only my best attempt to interpret what your textbook means.

Answer:

Arc length

formula = s = rθ

s = arc length (in radians)

r = radius

θ = central angle in radians

Step-by-step explanation:

For a circle, the arc length formula is θ times the radius of a circle. The arc length formula in radians can be expressed as, arc length = θ × r, when θ is in radian. Arc Length = θ × (π/180) × r, where θ is in degree, where, L = Length of an Arc.

The two broad logic reasoning methods are the inductive reasoning and the deductive reasoning

The option that gives the correct reasoning process is option C;

C. This is an example of deductive reasoning because a specific conclusion is reached from general fact

The reason the above option is correct is as follows;

Deductive reasoning or deductive logic or deduction is the reasoning process in which a conclusion is based on the condition of truth of the premises. It involves the linking of factual statements to arrive at a logical conclusion, in a top down approach

The difference between deductive reasoning and inductive reasoning is that with inductive reasoning, the aim is to develop a theory, while deductive reasoning is about giving an existing theory a test. Narrowing down the theory in a top down approach

Therefore, given that the statement is based entirely on factual data and states what is given on the data on the graph it does not expand on the observation, or generalizing but rather narrows down to a particular segment of the collected, the reasoning process is deductive

Therefore, it is a deductive reasoning process example given that the conclusion is specific to a part of available general facts and the correct option is option C.
