Answer:
(A)
Step-by-step explanation:
In option A
Options B, C and D will give us an irrational product. Therefore the expression in Option A ( ) will give a rational product.
Option A is the correct option.
So you would do 900÷18 to get the amount each worker is worth, which would be 50 minerals.
Answer:
19.2cm=h
Step-by-step explanation:
Let ABCD be a rhombus with AC and BD as its diagonals.
We know that the diagonals of a rhombus bisect each other at right angles.
Let O be the intersecting point of both the diagonals.
Let AC=24cm and BD=32cm
OA=AC/2
OA= 24/2=12cm
OB=BD/2
OB=32/2=16cm
In rt.ΔAOB by Pythagoras theorem we have
AB²=OA²+OB²
=(12)²+(16)²
=144+256
=400
AB=20cm
Hence, each side of the rhombus is of length 20cm
Area of rhombus=1/2*AC*BD
=1/2*24*32
=12*32
Area of rhombus=base*altitude
12*32=20*h
19.2cm=h
