Answer:
y =0
Step-by-step explanation:
From the equation;
8³ × 8⁻⁵×8^y = 8⁻²= 1/8²
From the laws of indices;
aⁿ×aⁿ = a^2n
Therefore;
8³ × 8⁻⁵×8^y = 8^(3+-5+y)
8^(-2+y) = 8^-2 ; but the bases are the same and thus the exponents are the same;
-2 + y = -2
y = 0
Answer is B Mr James
Lets convert all the fractions, percentages to decimals:_
Mr James: 5/8 = 0.625
Miss Smith: 0.61
Mrs Lawson: 9/16 = 0.5625
Mr Tosh: 0.58
Mrs Cagle 0.53
So Mr James corrected the most homework.
The answer would be the Blue sector.
Because 15% of 360° is 37.2
37.2 is only 2.8 away from 40 making it the closest!
Answer:
1. 10:8 = 5:4 (simplest form)
2. 860:400 = 43:20 (simplest form)
3. 4415:1200 = 883:240 (simplest form)
For this question the answer is x= 5, -1
