That is in standard form except the -7 would be written as a power next to the 10. As an ordinary number it is 0.000000475
Option B) 37.12 is the right answer
Step-by-step explanation:
It is given that the qudrilateral is a rectangle which means that opposite sides wil be equal and all interior angles will be 90 degrees
So
PS = 17
PQ = SR = 33
The diagonal PR will form a right-angles triangle with PR being the hypotenuse
So,
Base = SR = 33
Perpendicular = PS = 17
Hypotenuse = PR = ?
The Pythagoras theorem will be used to find the length of PR
So,

Taking square root on both sides

Rounding off to nearest 100th
PR = 37.12
Hence,
Option B) 37.12 is the right answer

80% of 90 is 72 and half of 140 equals 70. So 80% of 90 is bigger
6,4 is the correct answer
