Answer:
215
Step-by-step explanation:
105*2=210
210+5=215
How many points are there total? (3*100)+250 = 550
So far, he has 72 + 85 + 78, or 235
He needs 0.80 * 550 for a B, or 440 points
440 - 235 = 205 points on the final to get a B
Percentage-wise, he needs 205/250, or 0.82
X^6 - 8, because it is (x^2)^3 - 2^3
Answer:
log 5^3 = 3 log 5 = 3(0.69897) = 2.09691
Step-by-step explanation:
log 125 = log 5^3 = y; find y:
log 5^3 = 3 log 5 = 3(0.69897) = 2.09691
