Answer:
B. 3.52
Step-by-step explanation:
4.20+1.80=6.00
6.00 x .08 (8% tax)=.48 tax
6.00+ .48=6.48 total cost
10.00-6.48=3.52 change from a $10 bill
If the man works for $25 an hour ans spends $125 on materials he will have to make equal or more than what he spent
25x ≥ 125
then you divide 25 from each side and that will leave you with
x≥ 5
so this man need to work 5 or more hours to break even or make a profit.
answer:
have any notes for reference?
Step-by-step explanation:
The answer is .37 because .1 * 3 = .3 and .7 * .1 = .07
.3 + .07 = .37
Answer:
Step-by-step explanation:
Given the expression sin mπ/256 and cos mπ/256
If m = 2;
sin mπ/256 = sin 2π/256
sin 2π/256 = sin π/128
since 180° = π rad
sin π/128 = sin 180/128
sin 180/128 = 0.0245
cos mπ/256 = cos 2π/256
cos 2π/256 = cos π/128
since 180° = π rad
cos π/128 = cos 180/128
cos 180/128 = 0.9997
If m = 4;
sin mπ/256 = sin 4π/256
sin 4π/256 = sin π/64
since 180° = π rad
sin π/64 = sin 180/64
sin 180/64 = 0.04907
cos mπ/256 = cos 4π/256
cos 4π/256 = cos π/64
since 180° = π rad
cos π/64 = cos 180/64
cos 180/64 =0.9988
If m = 6;
sin mπ/256 = sin 3π/128
sin 3π/128 = sin 540/128
sin 540/128 = 0.0736
cos mπ/256 = cos 6π/256
cos 6π/256 = cos 3π/128
since 180° = π rad
cos 3π/128 = cos 540/128
cos 540/128 = 0.9973
