Answer:
6.71
You use pythagoras so you do:
6² + 3² = 45
square root 45 =6.71
If you divide 4.16 by 5.20 you get .8 which would be .80 cents a pound
Answer:
22
Step-by-step explanation:
The line where it says 2cm, extend that line to the top. You know have 2 triangles, call the one on the left A and the one on the right B
area of recntangle = bh
Rect A:
b = 5
h = 4 - 2
h = 2
bh = 5 x 2
bh = 10
Rect B:
b = 3
h = 4
bh = 4 X 3
bh = 12
Total = 10 + 12
Total = 22
This would be something like [5] or -[-5] which is absolute value (>.<)
