Answer: 27
Step-by-step explanation:
The given sequence : 13, 24, 35, ....
Here, first term : a= 13
Common difference: d=24-13 =11
The nth term of arithmetic sequence is given by :-
![a_n=a+(n-1)d](https://tex.z-dn.net/?f=a_n%3Da%2B%28n-1%29d)
It is given that the nth term is 299, so put
![299=13+(n-1)11](https://tex.z-dn.net/?f=299%3D13%2B%28n-1%2911)
Subtract 13 from both sides , we get
![286=(n-1)11](https://tex.z-dn.net/?f=286%3D%28n-1%2911)
Divide both sides by 11, we get
![26=n-1](https://tex.z-dn.net/?f=26%3Dn-1)
Add 1 on both sides , we get
![n=27](https://tex.z-dn.net/?f=n%3D27)
Hence, the value of n= 27
Answer:
L - W = 2 and 2L + 2W = 68
Step-by-step explanation:
The two equations here are going to be-
Length minus width equals 2
L - W = 2
And
Length x 2 + Width x 2 = 68
2L + 2W = 68
In order to find the speed at which the boat is traveling, we divide the distance it has traveled by the time elapsed:
2.5/20=0.125 miles/minute
Next, we want to find how long it took for the boat to travel 10 miles. Since it travels 0.125 miles every minute, we just divide:
10/0.125=80
Thus, it took 80 minutes for the boat to reach the bridge
I don't know the rest of the question but
$4.50 is looking good!!
<span>The survey had a sample and response bias. The survey only randomly selected sophomore students, when it needed to be a thorough survey of children in the LA school district, so the sample size is neither large enough or relevant. Secondly, because the survey was administered by the parents of the students, the students surveyed will be more likely to over-report their activity level.</span>
