   What is the volume of the right triangular prism?     

    V  =  (1/2)(4 ft)(3 ft) • 5 ft     

    V  =  30 ft³     

   _.     

   The graph shown here is the graph of which of the following rational functions?     

     B.   (x – 2) / (x + 1)(x – 3)     

   _.     

   a table is 1m by 1m has a napkin that covers 10% ?     

   1 m by 1 m  =  1 m²     

   10% of 1 m²  =  0.1 m²     

   assuming the napkin is square, it is sqrt(0.1 m²) on a side     

   sqrt(0.1 m²)  =  0.3162 m

   Ann's Grade is the average of four scores:three chapter tests and a final that counts as two chapter tests.     

   She scored 72, 90, and 75 on the chapter tests.     

   what score does she need on the final to have a grade of at least 80?     

   (72 + 90 + 75 + 2x ) / 5  =  80     

   (72 + 90 + 75 + 2x )       =  5 • 80 = 400     

                  237 + 2x          =  400     

                            2x          =  163     

                                      x  =  81.5  or higher     

   _.     

   Which one of the following functions is equivalent to sin (350)?     

   A. —sin 550    B. —sin 35°    C. sin 35°    D. sin 55°     

   sin (350)  =  – 0.173648     

   A.  – sin (550)  =  – (– 0.173648)     

   B.  – sin (35)    =      – 0.573576     

   C.     sin (35)    =        0.573576     

   D.     sin (55)    =        0.819152     

   None of them is equivalent.

   The estimated distance from Pluto to the sun is 5.91 x 109 kilometers.     

   What is the word form of the number 5.91 x 109?     

   5.91 x 10⁹ (5,910,000,000) is five billion, nine hundred and ten million     

   The exponent 9 means move the decimal point nine places to the right.

   What is the highest common factor of 1,296 & 960     

   1296     

   1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 81,     

   108, 144, 162, 216, 324, 432, 648, 1296     

   960     

   1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48,     

   60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960     

   _.     

   Suppose y varies inversely with x.     

   Write an equation for the inverse variation.y=3 when x=.5     

   When x and y vary inversely, the product of x and y will always be the same.     

   When y = 3 and x = 5, xy will always equal 15.  So, one equation is y = 15 / x

   how to make a decimal a whole number     

   7.0710678118654752     

   If you mean round it to a whole number . . . 7       

   _.     

   one kilometer is about 31/50 mile.     

   What decimal represents this length?     

   31 / 50  =  62 / 100  =  0.62     

   By the way, the actual conversion is 0.621371.
