Answer:
P = Rs2500
Step-by-step explanation:
Given that,
Amount, A = Rs 3025
Rate, r = 10%
Let time, t = 2 years
We need to find the sum if the amount is compounded annually. Using the formula of compound interest.
So, the sum of money is Rs 2500.
Answer:
B
Step-by-step explanation:
"Is the same as" means an = sign, necessary for an equation!
This is in slope-intercept form, so you can think of it as being y=mx+b. Invert m (the slope) and flip its sign, and then substitute the x and y values in and solve for b. The answer is y=7/2x-20.
It will take 40 minutes.
To solve, divide 60 by 3. 60 is how many minutes there are in a minute. 3 is how long it takes to paint 2/5 of the room. We do not need to use the number 2/5 in this situation. Now back to 60 divided by 3. The answer is 20 minutes. Now multiply 20 by 2 to get 2/3 of an hour. Therefore, it takes 40 minutes to paint 2/5 of a room.
