Answer: The answers are (a)1/8th (b) 0.125 (c) 12.5%
Step-by-step explanation:
How I drew this conclusion is, you have 8 letters in RECORDER so its 8/64 the same spot for every letter which simplifies to 1/8th. Now for the decimal divide 8 into 64 to get 0.125 decimal form. Lastly, for the percent 8 * 100 = 0.125 then 0.125 * 100 gets you 12.5%. Hope this helps you understand good luck.
Answer:
a) -3
b) 117
c) 100
Step-by-step explanation:
(a) 2(1)²-5(1)
1²= 1
2×1= 2
2-5= -3
(b) 2(9)²-5(9)
9²= 81
81×2= 162
162-45= 117
(c) 2(4)²-5(4) +2(8)²-5(4)
4²=16
16×2= 32
32-20= 12
8²=64
64×2= 128
128-40= 88
88+12= 100
hope it helps!
