A 4 wheeler that travels 52 miles on 5 gallons of gasoline. A second 4 wheeler travels 21 miles on 2 gallons of gasoline which car get better gas mileage.
Answer:
The second 4 wheeler gets better mileage
Step-by-step explanation:
First 4 wheeler:
52mi - 5gal
Second 4 wheeler:
21mi - 2 gal
To compare we have to make sure everything is equal so,
5÷2 = 2.5
so,
second 4 wheeler:
21*2.5=52.5 , 2*2.5=5
52.5mi - 5gal
52<52.5

To solve the problem we must know about the properties of logarithms.
What are the Properties of logarithms?There are four basic properties of logarithms:
[tex]\rm log_aU+ log_aV = log_a(UV)[/tex][tex]\rm log_aU - log_aV = log_a(\dfrac{U}{V})[/tex][tex]\rm log_aU^n = n\ log_aU[/tex][tex]\rm log_ab = \dfrac{log_xb}{log_xa}[/tex]The solution to the problem is 1.
Given to us
[tex]\rm log_{10}6+log_{10}45 - log_{10}27[/tex]
Evaluation of the Logarithmic expressionTo solve the problem we will use the [tex]\rm log_aU - log_aV = log_a(\dfrac{U}{V})[/tex] and [tex]\rm log_aU+ log_aV = log_a(UV)[/tex] properties of logarithms, thus the solution to the problem can be calculated as shown below,

[tex]=\rm {log_{10}(6\times 45)}-{log_{10}27}[/tex]
[tex]=\rm {log_{10}(\dfrac{6\times 45}{27})[/tex]
[tex]=\rm {log_{10}(\dfrac{6\times 45}{27})[/tex]

Dave receives 10% commission on his first $5000 in sales and receives 20% commission on any sales beyond the first $5000. If dave sells $7000 this month, what will Dave’s commission be for the month?
Answer:
Step-by-step explanation:
it a
Dave’s commission be for the month for sales worth $7000 is $900.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, Dave receives 10% commission on his first $5000 and receives 20% commission on any sales beyond the first $5000.
He made sales worth $7000 this month,
Therefore, For the first $5000 he receives,
= (10/100)×5000.
= $500.
And for the rest (7000 - 5000) = $2000 he receives,
= (20/100)×2000.
= $400.
So, In total, he received (500 + 400) = $900

Describe how the volume of a triangular prism and a triangular pyramid with the same dimensions are related.
Answer:
The relationship between the volumes of pyramids and prisms is that when a prism and pyramid have the same base and height, the volume of the pyramid is 1/3 of the volume of the prism.
Hope this helps!! ;)
volume of the prism is three times the volume of the pyramid with the same dimensions.
What is the volume?Volume is the measure of the capacity that an object holds.
Formula to find the volume of the object is Volume = Area of a base × Height.
Volume of a triangular prism = area of base triangle × length of the prism
The volume of a triangular pyramid = (1/3) × Base Area × Height
The relationship between a triangular prism and a triangular pyramid with equal bases and heights is that the volume of the prism is three times the volume of the pyramid.
Therefore, volume of the prism is three times the volume of the pyramid with the same dimensions.

A random telephone survey of adults (aged and older) was conducted by Opinion Research Corporation on behalf of CompleteTax, an online tax preparation and e-filing service. The survey results showed that of those surveyed planned to file their taxes electronically.
Required:
a. Develop a descriptive statistic that can be used to estimate the percentage of all taxpayers who file electronically. (to nearest whole number)
b. The survey reported that the most frequently used method for preparing the tax return was to hire an accountant or professional tax preparer. If of the people surveyed had their tax return prepared this way, how many people used an accountant or professional tax preparer?
c. Other methods that the person filing the return often used include manual preparation, use of an online tax service, and use of a software tax program. Would the data for the method for preparing the tax return be considered categorical or quantitative?
Complete Question
A random telephone survey of 1021 adults (aged 18 and older) was conducted by Opinion Research Corporation on behalf of CompleteTax, an online tax preparation and e-filing service. The survey results showed that 684 of those surveyed planned to file their taxes electronically (CompleteTax Tax Prep Survey 2010).
a. Develop a descriptive statistic that can be used to estimate the percentage of all taxpayers who file electronically. (to nearest whole number)
b. The survey reported that the most frequently used method for preparing the tax return is to hire an accountant or professional tax preparer. If 60% of the people surveyed had their tax return prepared this way, how many people used an accountant or professional
tax preparer?
c. Other methods that the person filing the return often used include manual preparation, use of an online tax service, and use of a software tax program. Would the data for the method for preparing the tax return be considered categorical or quantitative?
Answer:
a. A descriptive statistic that can be used to estimate the percentage of all taxpayers who file electronically is the measure of frequency, using percentage.
Therefore, we can say that the percentage of all taxpayers who file electronically is 67% (684/1,021 * 100).
b. If 60% of the people surveyed prepared their tax returns by hiring an accountant or professional tax preparer, the number of persons who used professionals is:
= 613 (1,021 * 60%)
c. The data for the method for preparing the tax return would be considered categorical.
Step-by-step explanation:
a) Data and Calculations:
Sample number of adults surveyed = 1,021
Number of those surveyed who planned to file electronically = 684
This means that those who planned to file manually = 337 (1,021 - 684)
b) Descriptive statistics summarize the basic features of the data set.
Categorical data groups data with similar characteristics together instead of using numerical values like quantitative data.
Angle B has a measure of 2.5 radians. A circle with a radius length of 2.6 cm is centered at Angle B's vertex. What is the length of the subtended arc along this circle?
______ cm
9514 1404 393
Answer:
6.5 cm
Step-by-step explanation:
The length (s) of an arc of a circle of radius r and angle θ is ...
s = rθ . . . . where θ is in radians
For your values, the arc length is ...
s = (2.6 cm)(2.5 radians) = 6.5 cm
The length of the subtended arc is 6.5 cm.

3.) AI 65 kom hr. Alfred can reach home in 50 minutes. At what speed should he drive his car
so that he can reach home 10 minutes earlier?
Answer:
He should drive his car at a speed of 81.25 kilometers per hour.
Step-by-step explanation:
With a velocity of 65 kilometers per hour, he reaches home in 50 minutes. What speed he needs to reach home 10 minutes earlier, that is, in 50 - 10 = 40 minutes?
To solve this, we use the relation between inverse proportion variables(as the velocity increases, time needed decreases), that is, a rule of three with line multiplication, instead of cross. So
65 kilometers per hour - 50 minutes
x kilometers per hour - 40 minutes
So
[tex]40x = 65*50[/tex]
[tex]x = \frac{65*50}{40}[/tex]
[tex]x = 81.25[/tex]
He should drive his car at a speed of 81.25 kilometers per hour.
