On Thursday evening Malcolm's bank balance was −£107.35On Friday morning·£1867.68 is paid into his bank account·£715.21 is paid out of his bank account. No other payments occur. Work out how much money is in Malcolm's bank account on Friday evening.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

answer: a.   one is a factor of every whole number since every number is divisible by itself.

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
