Answer:

66.91 km^2

Step-by-step explanation:

This answer will be long:

Interior angles of hexagon sum to  (4)(180) = 720   each is 120 degrees

 each side is 24/6 = 4 km    

    area of hexagon =  12  *  1/2 2 * (2 tan60) =<u> 41.5692 km ^2 </u>

L triangle   5 = hypot   leg1 = 4    leg2 = 3    area = 1/2 * 3 * 4 =<u> 6 km^2</u>

TOP triangle is 4 = hypot    leg1 = 3.464      leg2 = 2  

                                       area = 1/2 * 3.464 * 2 = <u>3.464 km^2</u>

R triangle  two legs = 4    area   = 1/2 * 4 x 4 =<u> 8 km^2 </u>

BOTTOM triangle   two sides = 4       use sin rule   sin40/4  = sin 100/x

                third side = 4/sin 40  * sin 100 = 6.1284 km

             semi perimter = ( 4 + 4 + 6.1284) / 2 = 7.0641 km

                Use Herron's rule for area =

                  sqrt ( 7.0641 (7.0641-4)(7.0641-4)(7.0641-6.1284) ) =<u> 7.878 km^2 </u>

<u> add all of the areas to get  66.91 km^2  (IF I made no math errors!) </u>

Samantha bought a refrigerator that is 3 1/2 feet wide, 5 1/2 feet tall, and 2 1/2 feet deep. How much space will the new refrig
Basile [38]

Answer:

48.125 ft³

Step-by-step explanation:

The space occupied by the new generator is the product of it's dimension:

The space occupied = Length * width * height

Space occupied = 3 1/2 * 5 1/2 * 2 1/2

Space occupied = 7/2 * 11/2 * 5/2

Space occupied = (7*11*5) / (2*2*2) = 385 / 8

Space occupied = 48.125 ft³

How does the division rule for exponents help in understanding why anything to the zero power is 1?
Nookie1986 [14]
In the division rule you subtract the exponents<span> when </span>dividing<span> numbers with the same base. </span>One<span> rule for exponents is that exponents add when you have the same base. This works for any number x that you want to plug in except for x = </span>0<span>,because </span>0/0<span> is indeterminate (it is like dividing </span>zero<span> by </span>zero<span>). No matter what number we use when it is raised to the </span>zero power<span> it will always be </span>1.
