Answer:
The density would be 2.89 g/ml
Step-by-step explanation:
To find this, we first need to find the mass of the rock. we can do this by subtracting the weight of the water and cylinder from the weight after the rock is added.
250g - 120g = 130g
Now we need to find the volume. To get this, we subtract the volume of the water before and after the rock is added.
75ml - 30ml - 45ml
Now we use the density formula and solve
D = m/v
D = 130g/45ml
D = 2.89 g/ml
Answer:
<em>The amount to be paid is rupee 1872.72</em>
Step-by-step explanation:
<u>Compound Interest
</u>
It occurs when interest in the next period is earned on the principal sum plus previously accumulated interest.
The formula is:
Where:
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
The initial amount is P=1800 at r=8% = 0.08 during t=6 months (t=0.5 years) compounded quarterly. There are 4 quarters in a year, thus n=4.
Calculating A:
A = 1872.72
The amount to be paid is rupee 1872.72
Cost divided by number of items equals each items cost
20/16= 1.25
$1.25
