Answer:
Step-by-step explanation:
We would apply the formula for determining simple interest which is expressed as
I = PRT/100
Where
I = interest at the end of t years
r represents the interest rate.
P represents the principal or initial amount deposited.
t represents the number of years of investment.
From the information given,
P = 1000
R = 2%
T = 5 years
Therefore,
I = (1000 × 2 × 5)/100
I = $100
The total amount in the account after 5 years would be
1000 + 100 = $1100
16 divided by 1
is 16 with remainder 0
= 16 R 0
= 16 0/1

Step-by-step explanation: Hope this help :D
Step-by-step explanation:
let gold fish= X
let Plecos fish= Y
X +Y = 17................(I)
13.49X + 3.25Y =198.61........(II)
solve simuteniously to get
X = 14
Y = 3.....therefore
she bought 14 gold fish and 3 plecos fish
Answer: [H+] = 10^-7.2
Step-by-step explanation:
Given that the PH of the solution = 7.2
Using the formula pH = –log[H+]. To get the H+ concentration from the pH, raise both sides by the base of 10. Then we have
10^ -pH = H+. with pH of 7.2,
Thus the answer to this problem is
[H+] = 10^-7.2
