Your answer would be B) 337.5 because there is 4 halfs in 2 which means you would multiply 75 by 4 which is 300 and the you have 1/4 which is half of 1/2 so you devide 75 by 2 which is 37.5 and then add that to the 300 which gives you 337.5

For this case we must simplify the following expression:

$\frac {1} {3} (x- \frac {1} {3}) - \frac {1} {2} (\frac {2} {3} x- \frac {1} {2})$

So, if we apply distributive property to the terms within parentheses we have:

$\frac {1} {3} x- \frac {1} {9} - \frac {2} {6} x + \frac {1} {4} =\\\frac {1} {3} x- \frac {1} {9} - \frac {1} {3} x + \frac {1} {4} =$

We simplify taking into account that:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the major sign is placed.

$- \frac {1} {9} + \frac {1} {4} =\\- \frac {4} {36} + \frac {9} {36} =\\\frac {-4 + 9} {36} =\\\frac {5} {36}$

Answer:

$\frac {5} {36}$

Math/Physics Problem <br> (I'd be glad if you solved one of them).

Whitepunk [10]

Answer:

19.2

76.8

Step-by-step explanation:

density × volume = mass

mass = 62.4 × (pi × (40/2)² × h)

mass = 78,374.4h

WD = m×9.8×h = 9.8mh

WD = 768,069.12h²

At h = 5

WD = 768,069.12×5²

= 19,201,728 ft-lb

= 19.2 million ft-lb

At h = 10

WD = 76,806,9.12 × 10²

WD = 76,806,912 ft-lb

= 76.8 million ft-lb
