Step-by-step explanation:
I just took the test
129° + x = 180°. [Linear pair]
=> x = 180° - 129°
=> x = 51°
Answer:
look at explanation (I go down the first column of scenarios and then move on to the right column)
Step-by-step explanation:
1) The first one will be same as original because the decrease and increase are the same, and happen right after each other so you get the same amount
2) Second one you get greater than original. You're doubling the initial value, and then decreasing by a smaller percentage, so you still get greater than your initial value
3) Third you get greater than original. You're adding 50% of the initial value, and decreasing by 33.5% of the new value, which will still give you more than the original
4) Fourth, you get greater than original. You're adding 60% of the initial value, and then decreasing by 40% of the new value, which will still give you greater than the initial value
5) Fifth you get less than the original. You're decreasing by 75%, and then adding 50% of the new value, which still gives you less than the initial value
Answer:
The rule of 72 is a formula used to measure the approximate time it will take for an investment to double. The word "approximate" should be highlighted, as it is not a 100% exact formula.
The formula used is to divide 72 between the interest rate paid by the investment. The result is the number of years in which the capital invested will double.
It is important to mention that at the interest rate or return on your investment you must subtract the inflation. For example, if the annual rate of return is 15%, and inflation is 5% per year, your net rate is 10%.
For example, if you have an investment of $ 10,000 in a mutual fund, which pays you 10% per year. If you calculate 72/10, you will see that your investment will double in 7.2 years.
Now, if there is an annual inflation of 2%, the calculation should be 72 / (10-2), with which the investment will double in 9 years.
