Answer:
15.3feet
Step-by-step explanation:
Given the scale model of a train as;
2cm = 3feet
We are to find the height of real train of height 10.2cm, we can write;
10.2cm = x
Divide both expressions
2/10.2 = 3/x
2x = 3×10.2
2x = 30.6
x= 15.3
Hence the height if the real train is 15.3feet
Answer:
Use the formula for calculating compound interest PN=P0(1+rk)Nk where P0 is the unknown, PN=10,000, N=10, k=1, and r=0.015. Substitute the values into the formula and simplify.
10000=P(1+0.0151)1⋅10
10000=P(1.015)10
10000=P(1.16054...)
8616.67=P
Therefore, rounded to the nearest dollar, the initial investment needs to be $8617 to have $10,000 in 10 years.
