Answer:
to two decimal places
= 6.04 mega joules
Step-by-step explanation:
The volume of the half tank
= πr²h
r= 2 m
h= 14/2= 7 m
Volume= 22/7 *2² *7
Volume= 88 m³
work (in mega-joules) needed to pump all of the water to the top of the tank
= Volume*mass density *acceleration*distance
= 88*1000*9.8*7
= 6036800 joules
In mega joules
= 6.036800 mega Joules
to two decimal places
= 6.04 mega joules

a) and b) are correct options
Answer:
17925
Step-by-step explanation:
3(1/4)=3.25
simple interest formula:
PV(1+it)=FV
we will divide the 72 months to convert it into years
72/12=6
15000(1+.0325*6)=17925
Here multiple all your numbers together only for that question tho ok
The answer is B estimated number is 20
