Answer:
142
Step-by-step explanation:
The first term of this arithmetic sequence is -10. The common difference is -8-(-10) = 2. The n-th term is ...
an = a1 +d(n -1)
an = -10 +2(n -1) = 2n -12
Then the 77th term is ...
a77 = 2(77) -12 = 154 -12
a77 = 142
The 77th term is 142.
Answer:
16. D. 180 inches
17. A. 1/20 pound
18. D. (2,6)
19. A. 2/8
20. D. 22
Step-by-step explanation:
16. every 5 feet is 60 inches there is 15 feet because 1 yard=3 feet so 60*3=180
17. when you round it upwards you would have 30/40 and 32/40 so it would be 2/40 and then simply 1/20 so therefore it would be 1/20
18. The cost of milk is 3 so that would be (3,y) then every gallon would be y so (3,1)
19. You know this because when you plug in all the other numbers none of the rest of them work but A so therefore it must be A
20. So first you would multiply 2*2*2*2=8 Then you would divide 172/8=22. So therefore your answer would be 22
Answer:
Breaking this down.
Step-by-step explanation:
SO basically 50mg each aspiring = 12.5
so? 12.5x4=50mg so he can take up to 4 aspirins per day.
To find the percentage, we simply do:
240 / 30 x 100
= 800%
The statement says what percent OF 30 IS 240, not what percent OF 240 is 30. Because you divided 30 by 240 and multiplied by 100, you got 12.5%. It is actually 800%
