Answer: Hence, Options (1), (2), (3), (6), (7) are correct.

Step-by-step explanation:

Since we have given the figure:

According to figure, we get that

Angle 1, Angle 2, Angle 4 are exterior angles.

Angles 6 and 8 are remote interior angles to the exterior angle 1.

Because ∠6+∠8 = ∠1

Angles 6 and 7 are remote interior angles to the exterior angle 2.

Because ∠6+∠7 = ∠2

Hence, Options (1), (2), (3), (6), (7) are correct.

if I have a 71 percent in a class and I take a final worth 10 percent of my grade and fail. what would my grade be? thanks in ad

maria [59]

I think you're asking for a numerical answer, but you didn't mention
your score on the final.

Since the final is worth 10% (one tenth) of the grade, that 71 that you
have going into the final is worth 9/10 of the grade. So the way you
calculate your overall average is

 Overall score = 1/10 of [ (71 x 9) + score on the final ] .

If you scored absolute zero on the final, your overall average would be

Overall score = (1/10) x [ (71 x 9) + 0 ] = (1/10) (639) = 63.9% .

That's the lowest overall score for the class that you can have.

The highest overall score you could have would be if you got 100% on the final.
Then
 Overall = (1/10) x (639 + 100) = (1/10) x (739) = 73.9% .

If you got a 50% on the final, your overall would be

 (1/10) x (639 + 50) = (1/10) x (689) = 68.9% .

In general, your overall score for the class, after the final, is going to be

 63.9% plus (1 tenth) of your score on the final.

Good luck !

Question 17 and 18 plz show ALL STEPS and HELP ME ASAP

NARA [144]

Answer:

17) 750/9 and 18) 364

Step-by-step explanation:

17. Summation of 75*(0.1)^i from i=0 to infinity, that is equal to 75*(Summation of (0.1)^i). Summation of (0.1)^I is a geometric series with a sum of 1/(0.9)=10/9. Hence the series have a sum equal to 75*(10/9)=750/9

18) It's a series with sum=1+3+9+27+81+243=364
