Answer: It will take him 1.68 years to recover his initial investment.
First, find the amount of extra money that he will make.
34,000 - 13,000 = 21,000
He will be making an extra 21,000 per year.
Now, divide the cost of his training by the amount of his increase.
35200 / 21000 = 1.68
That gives you the amount of years it will take him to pay off his investment.
Answer:
C) exclusive
Step-by-step explanation:
For exclusive events, P(A and B) = 0. In other words, both events can't happen at the same time.
For inclusive events, P(A and B) ≠ 0. Both events <em>can</em> happen at the same time.
Since 2 is not an odd number, the events are exclusive.
Answer:
C has a magnitud of 10.4 units and is directed 270° from the positive x-axis
Step-by-step explanation:
As it shows on the attached picture, the xA and xB have equal magnitudes but opposite directions, therefore they cancel eachother out in the x-axis.
However, the yA and yB are equal in magnitud, but have the same direction. So, the create a total vector the is completely on the y-axis and it's magnitude is 2*(sin(60°)*6)=10.4 units.
In order for C to cancel this vector, it's magnitude also needs to be 10.4 units, but pointing the other way. Therefore, the angle needs to be 270° from the positive x-axis.
Answer:
Cellphones have become an integral part of our life, whether we like it or not. It has pervaded every sphere of life, to the extent that even beggars have cell phones.
Step-by-step explanation:
1.Cell phones can be very distracting from more important events in a child’s life such as studying, doing homework, or even the street. Studies have shown that children are more likely to be hit by a car if they are talking or texting on a cell phone while crossing the street. Since cell phones can connect children to their friends and the Internet, they can take away from study or homework time
2.Cheating with cell phones has become a huge issue in many schools. Students can text answers under their desks during tests. Since many phones are now Internet compatible, children can sometimes even use a search engine on their phone to find answers to test questions. If the child is caught cheating they can face serious consequences from the school.
Basic facts:
1. Complementary angles add upto 90 degrees
2. Supplementary angles add upto 180 degrees
Let us consider the angle as x degrees
Therefore its complementary angle will be (90 - x) degrees
Also its supplementary angle will be (180 - x) degrees
As per the question the supplement of the angle is 6 times its complement angle.
Therefore we can write the equation as:
180 - x = 6 x (90 - x)
or, 180 - x = 540 - 6x
or, 180 - x + 6x = 540 (Bring the variables to left side)
or, -x + 6x = 540 - 180 (bring the numbers to the right side)
or, 5x = 360
or 5x/5 = 360/5 (divide both sides by 5)
or, x = 72
Therefor the angle is 72 degrees
Complement = 90 - 72 = 18 degrees
Supplement = 180 - 72 = 108 degrees
