Answer: B 2/5

Step-by-step explanation: Convert the mixed number 2 1/2 into an improper fraction first by multiplying the denominator (2) by the whole number part (2)and add the numerator (1) to get the new numerator. Place the new numerator (5) over the old denominator (2). And now inverse means opposite, so just flip it.

Finally: 5/2 inverse= 2/5

A regular decagon has a side length of 4 centimeters long if the decagon is divided into 10 congruent triangles each has an appr

ratelena [41]

Area of decagon is given by:
Area=1/2(nsr)
where:
n=number of sides
s=side length
r=height
thus the area will be given by:
Area=1/2(10*4*6.2)
Area=124 cm^2
