75

37

82

145

34

Step-by-step explanation:

Hypotenuse of a right angle triangle from pythagoras theorem is given by

h²=b²+a²

Making h the subject

h=√(b²+a²)

Where h is hypotenuse, b is base and a is the other side of a triangle

10²+24²=676

√676=26 units

72²+21²=5625

√5625=75 units

12²+35²=1369

√1369=37 units

18²+80²=6724

√6724=82 units

105²+100²=21025

√21025=145 units

16²+30²=1156

√1156=34 units

finlep [7]

Answer:

C) English

Step-by-step explanation:

I don't really know how to explain it, so I'll show you instead.

For science, there are 6 of 6 correct answers with a 0.5 chance of answering correctly.

So,

0.5 x 0.5 x 0.5 x 0.5 x 0.5 x 0.5 = 0.016

For English, there are 4 of 4 correct answers with a 0.25 chance of answering correctly.

So,

0.25 x 0.25 x 0.25 x 0.25 = 0.004

They will have to study English (0.004) because it is lower than science (0.016).
