Answer: 25
Step-by-step explanation:
Since, Total creepy-crawly creatures = 20
Out of which 80% are flies and 20% are spiders,
Thus, the total flies = 80% of 20 = 16
And, The total spiders = 20% of 20 = 4
Also, we know that the number of legs of a spider = 8,
⇒ Total legs belong to spiders out of 20 creepy-crawly creatures = 4×8 = 32
Again, the number of legs of a fly = 6
Thus, the total legs belong to flies out of 20 creepy-crawly creatures = 6×16 = 96
Hence, Total legs = 32 + 96 = 128
Answer:
Length of XM is 5.5 units.
Step-by-step explanation:
Given △XYZ where MZ is the angle bisector of ∠YZX . we have to find the length of XM.
A triangle with vertices X, Y, and Z. Side XZ is base. A line segment drawn from Z to M bisects ∠YZX into two parts ∠YZM and ∠XZM.
YZ=7 units, XZ=11 units and YM=3.5 units
By angle bisector theorem which states that an angle bisector of an angle divides the opposite side in two segments that are proportional to the another two sides of the triangle.
Hence,
⇒
⇒ MX=5.5 units.
Hence, length of XM is 5.5 units.
