If c = 4 and d = 5, find d:c

Given the angles in the diagram, what is the angle measurement of the missing angle?

Eva8 [605]

Answer:

150*

Step-by-step explanation:

Using the formula (n -2) x 180* we find that there is 4 sides (n) and in put it and simplify to make (2)x180*. From there we calculate there is 360* in this polygon, and subtract the degrees already provided. 360-210=150

(a) If U = {y:5 20), P= {7,8,12, 19; and Q = {12, 15, 17, 19), find PU Q and P-Q.

storchak [24]

Solution,

P={7,8,12,19}

Q={12,15,17,19}

P U Q={7,8,12,19} U { 12,15,17,19}

 ={ 7,8,12,15,17,19}

P-Q={7,8,12,19}-{12,15,17,19}

 ={7,8}

Hope it helps

Answer:

$17,500 at 8%
$17,500 at 14%

Step-by-step explanation:

The fraction that needs to be invested at the higher rate is ...

(11% - 8%)/(14% -8%) = 3%/6% = 1/2

Half the money should be invested at each of the rates:

$17,500 for 8% return

$17,500 for 14% return.

_____

If you let x represent the amount at the higher rate, then the total return is ...

14%x + 8%(35000 -x) = 11%(35000)

(14% -8%)x = (11% -8%)(35000) . . . . subtract 8%·35000

x = (11% -8%)/(14% -8%)×35000 . . . . divide by the coefficient of x

Note that this formula is exactly the one we started with, above.
