Answer:
3/10
Step-by-step explanation:
Numbers Given are:
1 1/2, 2 1/2, 1 2/3, and 2 5/6
The result at the end of all the math is 2 5/6.
1 2/3 + 2 5/6 = 4 1/2
Divide 4 1/2 by 1 2/3 to get 2 7/10.
Subtract 2 2/3 from 2 7/10 to get 1/5.
Multiply 1/5 by 1 1/2 to get 3/10.
So the number they thought of was 3/10.
The invested amount, A=£4000
Rate of interest on this amount, r=5% per annum.
Total interest on the amount £4000 after 1 year
.
The total amount after 1 year, P=£4000+£200=£4200
Amount remains after an annual prize of £150=£4200-£150=£4050.
Note that after providing the annual prize the amount remains is £4050 which is more than the invested amount of £4000 as the prize money is less than the interest gained.
Now, for the 2nd year, the 5% interest is on the principal amount of £4050, which will have more interest as compared to the interest of 1st year.
Again, after prize distribution, the total amount remains for the principal amount of 3rd year will be more than the principal amount of 2nd year. This sequence repeated every year and the total amount will increase every year.
So, it will never end, the full prize money can be awarded for infinitely many years.
Answer:
200 → 400 → 800 → 1600 → 3200
Step-by-step explanation:
starting at 200 and multiplying by 2 until you have 5 numbers.
Answer: 368
Step-by-step explanation: 80 divided by 5 is 16, so you would use 16 to find out how many students there are. To do that, you have to do 23 times 16, which is 368. Hope this helps!
Answer:
The number times both Mark and Jen will be at the beach on the same day over the next 30 days is 10 times.
Step-by-step explanation:
Every third day implies that they both go the beach and then have a two day break, and then go the beach on the day after.
Put simply, every third day implies one day in three days.
Based on the above, the number times both Mark and Jen will be at the beach on the same day over the next 30 days can be calculated by dividing 30 by 3 as follows:
Number times both Mark and Jen will be at the beach = 30 / 3 = 10
Therefore, the number times both Mark and Jen will be at the beach on the same day over the next 30 days is 10 times.
