24. Janet and Jack are walking in a two-day event to raise money for charity.
Serga [27]

Answer:

40 miles walk

Step-by-step explanation:

Let the miles walked by both of them be x at which money collected by same

for Janet

Fixed donation  asked = $7.50

money asked for walking 1 mile = $0.10

money made by Janet if he walks x miles = x*$0.10 = $0.10x

Total money collected by Janet = Fixed donation  asked + money made by Janet if he walks x miles

Total money collected by Janet =7.50 + 0.10x

For Jack

Fixed donation  asked = $5.50

money asked for walking 1 mile = $0.15

money made by Janet if he walks x miles = x*$0.15 = $0.15x

Total money collected by Jack = Fixed donation  asked + money made by Jack if he walks x miles

Total money collected by Jack =5.50 + 0.15x

we have to find miles at which money collected by both of them be same

and we have decided that it it as x mile walk then

Total money collected by Janet = Total money collected by Jack

7.50 + 0.10x = 5.50 + 0.15x

=> 7.50 - 5.50 = 0.15x - 0.10x

=> 2 = 0.05x

=> x = 2/0.05 = 40

Thus, at 40 miles walk money collected by both of them will be same

A new investment opportunity for you is an annuity that pays $3,350 at the beginning of each year for 3 years. You could earn 5.
ser-zykov [4K]

Answer:

Answer: e. 9535,17

The annuity pays $3350 at the beginning of each year during 3 years, which means that if you decide to invest on it, you could receive $3350 now (at moment 0), $3350 at the beginning of the next year (let’s say at the beginning of moment 1) and $3350 in two years (at the beginning of period 2).

To be able to know how much does those payments (that are going to happened in the future) worth today, one should discount futures values to moment zero. One could easily think of these payments as if they were three bank checks that worth $3350 each, to be paid in the dates mentioned before: at moment zero (now), in a year (moment 1) and in two years (moment 2). If one decided to go to a bank and ask the bank to have money in advanced using these three checks, the bank would gives us the equivalent of the checks' present value, which is  

Present Value= 3350 + \frac{3350}{1+0.055} +\frac{3350}{(1+0.055)^2}

Step-by-step explanation:

  • Take into account that times worth: is not the same 1 dollar today that one dollar into one year. This is why we use discount operation to express all values in terms of the same moment of time (that usually is moment zero).
  • Use discount to calculate present values: this consists on dividing future values by (1+i) ^ n, where i is the interest rate and n is the temporary distance between the future value and moment zero (if the payment is going to happend in year 2, n=2).
  • After discounting all futures values using the correct interest rate and the proper "n" for each future value, sum up all discount values, and you will have the present value of your future cash flow.

HELP DUE IN 15 MINS!
Sladkaya [172]

Answer:

B and D both lead to failure. I have no idea how to pick which one is right. I guess D but don't be surprised if it is B. The question tries to do too much.

D

Step-by-step explanation:

No.

You need one more fact.

You can't pick A. Angles are not noted.

B: there is no mention of parallel sides. This is why the proposition fails to give a parallelogram.

C: you haven't got both sides being parallel. You haven't even got one set of opposite sides being parallel

D: This is probably another alternative. You don't know anything about 1 set of opposite sides.

E: No angles are marked.
