Answer:
C. reflection
Step-by-step explanation:
it's like your reflection on a mirror.
Q + n = 40....q = 40 - n
0.25q + 0.05n = 5
0.25(40 - n) + 0.05n = 5
10 - 0.25n + 0.05n = 5
-0.25n + 0.05n = 5 - 10
- 0.20n = -5
n = -5 / -0.20
n = 25 <=== 25 nickels
q + n = 40
q + 25 = 40
q = 40 - 25
q = 15 <== 15 quarters
Answer:
Step-by-step explanation:
47= 3/44, so ratio is 3/44 for non-nuts muffins
Which mean, for every 44 muffins we would have 3 non-nuts muffins.
2√72 / √8 ± √2
If the denominator is √8 + √2,
2√72 / √8 + √2
= 2√(2*2*2*3*3) / √(2*2*2) + √2
= 2*2*3√2 / 2√2 + √2
= 12√2 / 3√2
= 4
