Nadusha1986 [10]

Answer:

1680 dollars

Step-by-step explanation:

7 + 4 = 11

77  \div 11 = 7

day \: 7 \times 7 = 49h

evening \: 7 \times 4 = 28h

24 \div 4 = 6

6 \times 3 = 18 (hourly \:  pay \: of \: evening \: job)

24 \times 49 = 1176

28 \times 18 = 504

total \: 1176 + 504 = 1680

Prove that the diagonals of a rhombus are perpendicular using coordinate geometry
lozanna [386]

If we draw a rhombus OABC on a coordinate grid with one vertex at the point O (0,0)

and let its height be 1 then (using the Pythagoras theorem) the coordinates of the 4 points will be as follows:-

O = (0,0) , A = (1, 1), B = (sqrt2+ 1 , 1) , C = (sqrt2, 0)

Slope of the diagonal OB = 1 / (sqrt2 + 1)

Slope of the other diagonal AC = - 1 / (sqrt2 - 1)

Product of the slopes = - 1 / ( sqrt2 + 1)(sqrt2 - 1) = -1 / 1 = -1

This proves that the diagonals are perpendicular.
