Answer:Yes, Naomi is incorrect.
Explanation: For explain this we can consider an example - Let us suppose Naomi deposited 100 rupees in her saving account at the rate 6% for 1 year .
Now, if the interest is quarterly then according to the formula
compound interest =
-P where r is the rate annually and n is the number of years.
so CI=
-100 ( here the rate is already given in quarterly)
CI=
-100= 1.26247696-100=26.247696 rupees=26(approx)
Now, if the compound interest is 1.25 per month then again from the formula-
CI=
-P
CI=
-100= 100(1.16075452)-100=16.075452=16(approx)

16. 10 ml of 20% saline and 40 ml of 10% saline
Step-by-step explanation:
A chemist takes x ml of 20% saline and y ml of 10% saline. In total, he takes
x + y ml that is 50 ml, so

There are
ml of salt in x ml of 20% saline and
ml of salt in 10% saline. There are
ml of salt in 50 ml of 12% saline. Thus,

15. We get the system of two equations:

16. Solve this system. From the first equation:

Substitute it into the second equation:

Answer:
Volume of Shipping box= lenghth × breadth × height
Volume of ring box= side × side × side
Step-by-step explanation:
Volume of ring box = 12×12×12
=1728 units
Volume of shipping box= 1012×8×3
=24288 units
number of ring boxes in shipping box= 24288/1728
= 14.
Hope am correct
Thanks
