. Andrew is deciding whether to purchase Car A or Car B. He wants
to buy the car that has the best mileage per gallon of gas. Car A
gets 23.7 miles per gallon of gas. Car B can travel 374 miles on
17 gallons of gas. Which car has the better gas mileage?
A. Car A
B. Car B
C. They have the same mileage. D. You need more information. .
Answer:
B. Car A
Step-by-step explanation:
To find the unit rate divided 374 and 17
374 ÷ 17 = 22
Car B 22 miles per gallon
Car A 23.7 miles per gallon
Car A is a better by because it has more mileage.
Are the ratios 9:18 and 1:2 equivalent?
Answer:
yes
Step-by-step explanation:
(1:2)x2=9/18
yes the ratios 9:18 and 1:2 equivalent
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
We need to check whether the ratios 9:18 and 1:2 are equivalent.
Equivalent ratios are the ratios that are the same when we compare them.
Two or more ratios can be compared with each other to check whether they are equivalent or not.
Here the two ratios are 9:18 and 1:2
We can write 9:18 as fraction 9/18
When we simplify it we get 1/2
Hence, yes the ratios 9:18 and 1:2 equivalent

[tex]\rm \lim \limits_{n \to \infty } {n}^{ - \frac{1}{2} ( \frac{n + 1}{n} )} (1 \times {2}^{2} \times {3}^{2} \times \dots \times {n}^{n} {)}^{ \frac{1}{ {n}^{2} } } [/tex]
[tex]\rule{200pt}{2pt}[/tex]
[tex] \rm I= \sum \limits_{k = 1}^{98} \int_{k}^{k + 1} \frac{k + 1}{x (x+ 1)} \: dx, then \\ [/tex] [tex] \rm[A] \phantom{gg}I>log_e99 \\ \\ \rm [B] \phantom{gg}I < log_e99 \\ \\ \rm[C] \phantom{hffgg} I < \frac{49}{50} \\ \\ \rm[D] \phantom{gfffg} I > \frac{49}{50} \\ [/tex]
Using the exp-log technique,
[tex]\displaystyle \lim_{n\to\infty} \frac{\left(1 \times 2^2 \times 3^3 \times \cdots \times n^n\right)^{\frac1{n^2}}}{n^{\frac{n+1}{2n}}}[/tex]
[tex]\displaystyle = \exp\left(\lim_{n\to\infty} \frac{\ln\left(\prod\limits_{k=1}^n k^k\right)}{n^2} - \frac{n+1}{2n} \ln(n)\right)\right)[/tex]
[tex]\displaystyle = \exp\left(\lim_{n\to\infty} \frac{\sum\limits_{k=1}^n k\ln(k)}{n^2} - \frac{n+1}{2n} \ln(n)\right)\right)[/tex]
We have ln(k) = ln(k/n) + ln(n), and so we can rewrite the limand as
[tex]\displaystyle = \exp\left(\lim_{n\to\infty} \left(\frac1n \sum\limits_{k=1}^n \frac kn \ln\left(\frac kn\right) + \frac{\ln(n)}{n^2} \sum_{k=1}^n 1 - \frac{n+1}{2n} \ln(n)\right)\right)[/tex]
Then the first sum converges to a definite integral,
[tex]\displaystyle \lim_{n\to\infty} \frac1n \sum_{k=1}^n \frac kn \ln\left(\frac kn\right) = \int_0^1 x \ln(x) \, dx = -\frac14[/tex]
while the remaining terms vanish since
[tex]\displaystyle \frac{\ln(n)}{n^2} \sum_{k=1}^n 1 = \frac{\ln(n)}{n^2} \times \frac{n(n+1)}2 = \frac{n+1}{2n}\ln(n)[/tex]
So the limit is [tex]\boxed{e^{-1/4}}[/tex].
Since
[tex]\dfrac1{x(x+1)} = \dfrac1x - \dfrac1{x+1}[/tex]
it's easy to show that the integral reduces to
[tex]\displaystyle \int_k^{k+1} \frac{k+1}{x(x+1)} \, dx = (k+1) \ln\left(\dfrac{(k+1)^2}{k(k+2)}\right)[/tex]
so we can write the sum as
[tex]I = \displaystyle \sum_{k=1}^{98} \int_k^{k+1} \frac{k+1}{x(x+1)} \, dx = \sum_{k=2}^{99} k \ln\left(\frac{k^2}{k^2-1}\right)[/tex]
We have k²/(k² - 1) > 1 for all k, so that ln(k²/(k² - 1)) > ln(1) = 0. We can see the first 3 terms of the sum already exceed 1 > 49/50, so (D) is true.
Numerical computation of the sum suggests I < ln(99), but I have yet to come up with an analytical solution for this bound...

What role do plants play in the nitrogen cycle?
Answer:
Plants absorb nitrates from nearby soils to create proteins. Fertilizer also helps because it makes the soil even richer, allowing for more nitrates, which means more proteins.
You have listed a property. The seller told you that he must net at least $14,000 after all the fees and expenses are paid. You estimate the seller's closing cost to be $3,500, and he must payoff an existing loan of $108,750. In addition, you are going to charge 7 percent commission on the sale. What is the LEAST amount that the property can sell for to return the seller's desired net?

On each of ner birthdays. Bernadette blew out a number of candles
equal to her age in years. She lived to be 107. How many candles
did she blow out during her lifetime? (She had some help the first
few years but they all count)
Answer:
5778
Step-by-step explanation:
1+2+3+4+5+....+105+106+107
The sequence of numbers (1, 2, 3, … , 107) is arithmetic and when we are looking for the sum of a sequence, we call it a series. Thanks to Gauss, there is a special formula we can use to find the sum of a series:
S=n(n+1)/2=11556÷2=5778
S is the sum of the series and n is the number of terms in the series, in this case, 107
There are other ways to solve:
This is an arithmetic series, for which the formula is:
S = n[2a+(n-1)d]/2
where a is the first term, d is the difference between terms, and n is the number of terms.
For the sum of the first 107 whole numbers:
a = 1, d = 1, and n = 107
Therefore, sub into the formula:
S = 107[2(1)+(107-1)(1)]/2 =
107(2+106)/2=107*108/2=5778
so she blow out 5778 candless during her lifetime

a motorist left home at 10 a.m. to travel to a cityof a distance of 260 km he reckoned hecould average 80km/ h at what time would he arrive at the city
Answer:
He would get there at 1:15 (I did this in my head, may be wrong)
Step by step solution:
We know the motorist left home at 10. We can divide the 260/80 and we get 3 hrs, we still have 20 km left over, keep on dividing and you get 1:15 p.m.

Emma spent $60.20 on 5 dozen bagels and a gallon of iced tea. The price of the gallon of iced tea was $5.25. The following equation can be used to find d, the price of each dozen of bagels. 5d + 5.25 = 60.2 What was the price of each dozen of bagels?
23.23 - 5.25 = 17.98
d = 17.98 ÷ 2
d = 8.99
The answer is B. $8.99
