It took 48 minutes to drive downtown An app estimated it would be less than that If the error was 20% what was the apps estimate
Zina [86]

Answer:

<em>The app's estimate was 38.4 minutes.</em>

Step-by-step explanation:

Suppose, the app's estimated time was t minutes.

Given that, it took 48 minutes to drive downtown. So, <u>the error in estimated time by the app</u> =(48-t) minutes.

It is also given that the error was 20%. So, <u>the amount of error</u> = (48*0.20)=9.6 minutes.

Thus, the equation will be......

48-t= 9.6\\ \\ -t=9.6-48\\ \\ -t=-38.4\\ \\ t= 38.4

So, the app's estimate was 38.4 minutes.

A series is defined by 5+9+13+17+.......+805 a. Find the number of terms of the series. b. Find the sum of the first 20 terms.​
puteri [66]

Answer: the number of terms of the series is 201 numbers

              the sum of the first 20 terms is 890    

the number of terms of the series is \frac{805-5}{4}+1=201

the series have:

u1 = 5

d = 4

=> u(n) = 5 + 4.(n - 1)

=> u(20) = 5 + 19.4 = 81

so the sum of the first 20 terms is (81 + 5).20/2 = 890

( u1 is the first number of the series, d is the  distance between front and rear numbers, u(n) is the overall term of the sequence, u(20) is the 20th of the series)
