Answer:
9 cents per day
Step-by-step explanation:
1 week = 7 days
Each razor lasts 1 week = 7 days
10 razors last 10 weeks = 10 * 7 days = 70 days
cost per day = (total cost)/(number of days)
cost per day = $6.30/(70 days) = $0.09/day

Answer:
It should be 62
Step-by-step explanation:
30+40-8=62
Answer: 80
Step-by-step explanation:
Triangles equal 180 therefore 50+50=100 and 180-80=80
For this case we represent in the complex plane numbers of the form:
a + bi
Where,
a: real part
bi: imaginary part
We represent the real part on the x axis.
We represent the imaginary part in the y axis.
Therefore, for the following numbers we have:
-3 + 8i: quadrant 2
4i: on the vertical axis
6: on the horizontal axis
5-2i: quadrant 4
