Answer:
During the first year he had an annual interest of 12%, and in the second year of 25%
Step-by-step explanation:
To calculate the interest of the first year:
(Initial capital of the first year / final capital of the first year) - 1 = interest of the first year
(300/336) - 1 = 0.12 = 12%
To calculate the interest of the second year:
(Initial capital of the secondyear / final capital of the second year) - 1 = interest of the second year
(336/420) - 1 = 0.25 = 25%
Answer:
2/5: 4/5
Step-by-step explanation:
2/5 of a mile : 16/20 of a mile
It can be made equivalent in 2 ways. Either make the first fraction equivalent by multiplying it with 4 or make the second fraction equivalent to the first by dividing it by 4
- 2*4/5*4: 16/20
= 8/20: 16/20
2. 2/5: 16/4/20/4
= 2/5: 4/5
It is better to choose a smaller fraction as they are easy to solve .
So the total distance he covered = 2/5+ 4/5= 6/5= 1 1/5 miles or 1.20 miles from school to home.
|-3| is an absolute value. This means it will always be positive. -3 is an integer and is negative.
D is correct:
because of doing the correct steps:
step1: put the point of your compass on the left endpoint of the segment, A.
Open the compass to be more than half the length of the segment. Then leave a half-circle mark.
step2: do the same thing on the other point B. and find the middle point.
Since 8 and 20 both have a common factor, which is 4, you divide both of them. 8/4=2 and 20/4=5
12 2/5
