Answer:

60

Step-by-step explanation:

The corresponding angles of the triangles are given, y + 10 and 2y - 40. You need to first find the value of the variable (in this case, y), and to do this, you need to set them equal to one another:

y + 10 = 2y - 40

<u>Subtract y from both sides:</u>

<u />

y + 10 = 2y - 40

-y          -y

____________

10 = y - 40

<u>Add 40 to both sides:</u>

<u />

10 = y - 40

+40    +40

________

50 = y

Now that we have the value of y, you need to plug the value into one of the expressions (either one will come out with the same answer):

y + 10

50 + 10 = 60

<em><u>OR</u></em>

<u />

2y - 40

2(50) - 40

100 - 40 = 60

<u />

Total = Principal × ( 1 + Rate ) ^ years

(Solved by taking logarithms)

Years = log (total / principal) / (log (1 + rate))

Years = log (684 / 600) / (log 1.07)

Years = log (1.14) / (log (1.07)

Years = 0.0569048513364726 / 0.0293837776852097

Years = 1.9366077414

Which factor is important to consider when building a savings fund for planned,long term needs ?
netineya [11]

Answer:

Principal amount of investment.

Interest rate.

Simple or compound interest.

Time to hold the investment.

Step-by-step explanation:

There are several factors to consider when building a savings fund for planned long term needs.

First of all, we have to consider the amount of principal money we can invest in. It may be a one-time investment or a systematic investment plan. I case of a one-time investment we can easily calculate the investment amount but in case of monthly or yearly investment, we have to be sure that we will be able to invest the amount for the said period of time.

Second is the interest rate that the fund is giving i.e. APR of the fund. Again, take care to identify whether it is a simple interest or compound interest. Obviously the compound interest is better than simple interest as it gives more interest.

The third is the time for which you can hold the money without withdrawal. (Answer)
