Answer:
Only Katie is correct.
Step-by-step explanation:
Suppose the amount is $50.
Find the 40% by Tom's method:
50 / 100 = 0.5
0.5 * 4 = $2
- which is 4% of 50.
By Katie's method
50 / 5 = 10
10 * 2 = $20
- which is 40% of 50.
Answer:
h=7ft
Step-by-step explanation:
sinФ=opposite/hypotenuse
sin45°=5/h
0.71=5/h
multiply via by h
0.71h=(5/h)h
h cancel h it remains 5
0.71h=5
divide through by 0.71
0.71h/0.71=5/0.71
h=7.04ft
h=7ft approximately
