Answer:
You would have to find the area of the whole rectangle without the spece, so it would be 30mm x 15mm, the result would be 450 square mm.
Then you find the area of the empty space which would be 10mm x 8mm, the result: 80 square mm.
You substract the area of the space from the whole rectangle, which would be 370 square mm, this is the area of the figure
Answer:
2/5 > 1/4
Step-by-step explanation:
2/5 = 4/10 = 0.4
1/4 = 0.25
0.4 > 0.25
2/5 > 1/4
The root
can be converted into the power
. Therefore we can rewrite the problem as
and then follow the exponent rules about a power to a power, multiplying 1/2 and 3/4 together.
Thus the problem becomes
, which then can be turned into
, making the last option our answer.
