The Browns plan to fly to their vacation spot and then drive
through the mountains. They arranged to rent a sedan for
$37.45 per day with no charge for mileage.
a. What will it cost the Browns to rent the car for 10 days if
they spend $78.00 for gasoline?
b. What will it cost per mile if they drive 590 miles?
Answer:
a) $452.50 b) $0
Step-by-step explanation:
Let's answer Part A first.
The final cost of the rental will be called X
x = (37.45 * 10) + 78
x = 374.50 + 78
x = $452.50
Part B:
There is no cost for mileage.

A compact car depreciates at 10% per year three years ago it was purchased for 21,000. Whats it worth now? Pls help me
Answer:
Step-by-step explanation:
Methods of depreciation
In practice, several different methods for calculating depreciation are used. These methods can be either based on the passage of time or the level of usage of the asset. The following depreciation methods can be applied to different types of tangible assets:
Note that at the end of an asset lifespan, the total amount of its depreciation will be identical, no matter which method of depreciation is applied. The only thing that varies over the different methods of depreciation is the timing (the amount of money that is depreciated over the smaller periods).
In the further part of this text, we will focus on the description of the three most commonly used types of depreciation: the straight line depreciation, the declining balance depreciation, and the sum of years digits depreciation. We're going to pay attention especially to the depreciation formulas and the detailed explanation of how to calculate the value of depreciation with each of them.
Residual value and depreciation
As was already mentioned, residual value (salvage value) is an estimated amount of money that an asset will be worth after the planned number of years of use. Obviously, in real life, it is impossible to accurately predict the exact salvage value of an asset after a particular number of years.
That means that the salvage value is only an approximation. However, in accounting, this approximation is just a kind of a transition state. It is because when you sell an asset, if the cash received for it is greater than its net book value (Initial Value minus Accumulated Depreciation), you will need to record a gain on sale. On the other hand, if you sell an asset below its net book value, you will need to record a loss on sale.
Note here that, if this number of years in use is equal to the product lifetime, the residual value is zero.
Car depreciation calculator
For sure, one of the most interesting cases of depreciation is the loss of value of a motor vehicle. As you probably know, the value of a brand new car decreases sharply as soon as you drive off of the car dealership (experts say that the value of a car decreases to 91% of the initial value the minute you purchase it!). Over the next years, the value of the car decreases, until after several years (around 10 to 11), it reaches zero value. Obviously, you will still be able to sell it. However, its market value will be very low. To avoid the hassles of selling a used car, many people prefer leasing a car these days instead of buying one.
If you are interested in detailed car depreciation calculations, be sure to look at our car depreciation calculator. It uses a model more specific to automobiles.
How to use our depreciation calculator?
Our smart depreciation calculator enables you to compute the yearly depreciation and to determine the value of an asset after a certain time has passed on the basis of the three most commonly used methods. They are the straight line depreciation, the declining balance depreciation, and the sum of years digits depreciation.
To get results using our calculator, all you need to do is to fill in four fields:
Original cost - the original value of the asset (purchasing price),
Residual value - an estimated amount of money that an asset will be worth after the lifetime has elapsed (it is usually assumed that it is equal to zero, for more information see section Residual value and depreciation),
Lifetime - the estimated number of years the asset is likely to remain in service,
End book value after… - in this field, you should provide the year after which you would like to compute the book value of the asset.
And that's it! In a moment, our depreciation calculator computes three variants of depreciation. If you are curious how it works, you should get familiar with the depreciation of the formulas described in the following sections of the article. Each formula uses the same set of symbols:
OV is the original cost (value) of the asset,
RV is the residual value of the asset,
n is the lifetime of the asset,
m is the number of years that passed between when the asset was purchased and the date you want to sell it (it corresponds with the field End book value after… in the calculator).

Increase 12% by 30%
Answer:
Introduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
30% = 30/100 = 30 ÷ 100 = 0.3.
100% = 100/100 = 100 ÷ 100 = 1.
Increase the number by 30% of its value.
Calculate the New Value
New value =
12 + Percentage increase =
12 + (30% × 12) =
12 + 30% × 12 =
(1 + 30%) × 12 =
(100% + 30%) × 12 =
130% × 12 =
130 ÷ 100 × 12 =
130 × 12 ÷ 100 =

Imani and Samuel are designing a game. In each turn, a player rolls three 666-sided dice and adds the numbers showing on each face to determine how many points they get that turn. For example, the lowest number of points in a given turn is 1+1+1=31+1+1=31, plus, 1, plus, 1, equals, 3 points, and the highest is 6+6+6=186+6+6=186, plus, 6, plus, 6, equals, 18 points. They let XXX represent the sum in a given turn, and they find the expected value of XXX is E(X)=10.5E(X)=10.5E, left parenthesis, X, right parenthesis, equals, 10, point, 5 points. Imani says, "After a very large number of turns, the average number of points per turn will be close to 10.510.510, point, 5." Samuel says, "Over 100100100 turns, we can expect a total of about 1{,}0501,0501, comma, 050 points." Whose statement is correct based on the expected value?
Answer:
C:Both
Step-by-step explanation:
Got it fight on Khan Academy
Both of these statements are correct
What is expected value?
In statistics, expected value is computed by multiplying all the possible outcomes by the likelihood of occurrence of each outcome and then summing all of those values. In simpler terms, expected value is the mean of a probability distribution.
Here, expected value of the sum is given by E(X)= 10.5
Imani says- "After a very large number of turns, the average number of points per turn will be close to 10.5"
This statement is correct as the expected value is also the mean of the probability distribution and hence after very large number of turns, the average number of points per turn will be close to the mean value i.e. 10.5.
Samuel says, "Over 100 turns, we can expect a total of about 1,050."
This statement is also correct. Since the expected value is 10.5, in 100 turns, we can expect on average 10.5 points per turn.
∴ Total points in 100 turn = 10.5 * 100 = 1,050.
Hence, both Samuel and Imani are correct.

In the diagram below, DE is parallel to AB. If AB is twice the length of DC,
AC = 28, and DE = 13, find the length of DC. Figures are not necessarily drawn
to scale. State your answer in simplest radical form, if necessary PLEASEEE
Answer:
13.4
Step-by-step explanation:
AB =2DC
So, DC=AB/2
Now, AB/AC=DE/DC
AB/28=13/(AB/2)
AB²=13×28×2
AB=√728
AB=26.98
now, DC=AB/2
=13.4
The length of DC is √182.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .
DE is parallel to AB.
If AB is twice the length of DC, AC = 28, and DE = 13
We have to find the length of DC
DC/AC=DE/AB
x/28=13/2x
Apply cross multiplication
2x²=13×28
2x²=364
Divide both sides by 2
x²=364/2
x²=182
x=√182
Hence, the length of DC is √182.

since the tens place is a square, but cannot be larger than the ones place, it has to be either 1 or 4the hundreds place is a cube which can be 8 not one since the digit in the hundred thousand places is both a square and a cube which is 1also, the number is divisible by 5 meaning that the last digit must be 5 or zero. However, only the hundreds place is larger than the digit in the ones place so it must be 5Looking at what we have so far:
1 _ _ 8 4 5
this number is divisible by 3 and cannot be larger than 5 which is in the units placewhen a number is divisible by 3 all its digits must add to a number that is divisible by 3, meaning that the last unfilled digits can be filled by '0' and '3'now the order of '0' and '3' is determined by whether the number is divisible by 7Result: 103845 is the secret number
