For three consecutive years the cost of gasoline increased by 8%, 15%, and 20%, respectively. What was the overall percentage increase of the cost of gasoline during the three-year period?
Answer: 24.84%
Step-by-step explanation:
I don't really know how to explain step-by-step from my messy notes
The overall percentage increase of the cost of gasoline during the three-year period is 14.33%.
What is percentage?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%.

The circle graph shows the results of a survey of registered voters the day of an election Which Party's Candidate Will Get Your Vote? Other: 4% Green: 2% Libertarian: 5% Democratic 47% Republican: 42% Error: 2% The error given in the graph means that the actual percent could be 2% more or 2% less than the percent reported by the survey a. What are the minimum and maximum percents of voters who could vote Republican? Green? The minimum percent of voters who could vote Republican is % and the maximum is %. The minimum percent of voters who could vote
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.

OB. This is an example of deductive reasoning because a general conclusion is reached based on a specific example
O C. This is an example of deductive reasoning because a specific conclusion is reached from general facts.
OD. This is an example of inductive reasoning because a specific conclusion is reached from general facts,
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.

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.

Suppose Lisa places $6000 in an account that pays 18% interest compounded each year. Assume that no withdrawals are made from the account.
Follow the instructions below. Do not do any rounding.
(a) Find the amount in the account at the end of 1 year.
(b) Find the amount in the account at the end of 2 years.
Step-by-step explanation:
The formula for compounded interest is given by
[tex]A = P\left(1 + \dfrac{r}{n}\right)^{nt}[/tex]
where
A = amount of money after a time t
P = principal or initial amount of money
r = interest rate in decimal form
n = number of times money bnb is compounded per unit time
t = unit time
a) For this problem, P = $6000, n = 1 since the money is compounded once a year, t = 1 year and r = 0.18 so after one year, Lisa's money amounts to
[tex]A = (\$6000)\left(1 + \dfrac{0.18}{1}\right)= \$7,080[/tex]
b) After two years, the money is still compounded yearly so n = 1 but t = 2 years so Lisa's money amounts to
[tex]A = (\$6000)\left(1 + \dfrac{0.18}{1}\right)^{2} = \$8354.40[/tex]
Step-by-step explanation:
a)
Principal = $6000
Rate = 18%
Time = 1 year
A = P(1 + r/100)¹
A = 6000(1 + 18/100)
A = 6000(100 + 18/100)
A = 6000 × 118/100
A = 60 × 118
A = 7080
b)
Principal = $6000
Rate = 18%
Time = 2 years
A = P(1 + r/100)²
A = 6000(1 + 18/100)²
A = 6000(100 + 18/100)²
A = 6000(118/100)²
A = 6000 × 118/100 × 118/100
A = 6 × 118 × 118/10
A = 8354.4

A motorboat can maintain a constant speed of 45 miles per hour relative to the water. The boat makes a trip upstream to a certain point in 34 minutes; the return trip takes 26 minutes. What is the speed of the current?
The speed of the current is _ mile(s) per hour.
Answer: Distance upstream = (34-c)(39/60) miles
--------------------------
Distance downstream = (34+c)(29/60) miles
-----------------------------------------------
Equation:
distance = rate*time
distance up = distance down
(34-c)(39/60) = (34+c)(29/60)
Multiply both sides by 60 to get:
39(34-c) = 29(34+c)
39*34 - 39c = 29*34 + 29c
68c = 340
c = 5 mph (speed of the current)Step-by-step explanation: I'm not sure if this will help you but I hope it does!

Write an equation in Slope-Intercept Form with a slope of 12 and passes through (−4,3).
Answer:
y = 12x + 51
Step-by-step explanation:
y = mx + b, where m is the slope and b is the y-intercept
The equation of line with a slop of m = 12
y = 12x + b
Since the point (-4,3) is on the line, it will satisfy the equation 3 = 12 (-4) +b
b = 3 - 12(-4)
b = 51
y = 12x + 51

E.
Figure A was rotated
90
°
about a point in the middle of the figures to create Figure B.
Answer:
B
Step-by-step explanation:
Process of elimination, it wasn't reflected because point a and point E are on opposite sides in figure B compared to figure A. It wasn't rotated 90° Because point H is once again on the complete opposite side, if it was 90° it would be to the left or the right, not opposite. It wasn't translated Because all points are in different places.
