Answer:
421160 Rupees
Step-by-step explanation:
Base area of cylinder = π × r^2
=> 616 = 22/7 × r^2
r^2 = (616 × 7) ÷ 22
= 4312 ÷ 22
= 196
Therefore r = √196
= 14 m
Total height of the tank = 20 m
Therefore height of cylinder
= 20 - 14
= 6 m
Volume of water tank
= Volume of cylinder + Volume of hemisphere
= π × r^2 × h + 2/3 × π × r^3
= 22/7 × 14 × 14 × 6 + 2/3 × 22/7 × 14
× 14 × 14
= 22/7 × 14 × 14 ( 6 + 2/3 × 14 )
= 616 ( 15.3 )
= 9424.8 m^3
= 9424800 l
( to convert m^3 to litre, multiply volume value by 1000 )
Total cost to fill water
= 9424800 × 45
= 424116000 paise
= 4241160 Rupees
Answer:
y=-12/5x+62
Step-by-step explanation:
to solve this i turned two point form, 5,50 and 17 1/2,20, into slope intercept form by using the formula y-y1=(y2-y1/x2-x1)(x-x1), which when input with the data becomes y-50=(20-50/17 1/2-5)(x-5) which then becomes y-50=-12/5(x-5), then y-50=-12/5x+12, and finally y=-12/5x+62
Answer:
D is the correct answer.
Step-by-step explanation:
When given points, one way to tell if it is a function is to see if the x-coordinate changes. If all the x-coordinates are different, then it is a function. If there is a group of x-coordinates that are the same, then you need to check the y-coordinate. If the y-coordinate is the same with the same x-coordinate, then it is still a function [Example: (12, 15), (12, 15) is a function, but (12, 15), (12, 18) is not)
Answer:
Step-by-step explanation:
A = P[1 + (r/n)]^(nt)
Look the formula up online to find out what each variable represents if needed.
We are solving for P, which is the principal amount 5 years back.
Substitute 11,000 for A (total amount), 4.5% for r(rate), 2 for n(number of times -- in this case, semiannually), and 5 for t(time -- 5 years).
11000 = P[1+(0.045/2)]^(2x5)
11000 = P (1.0225)^10
11000 = P (1.2492) approx.
Divide both sides by 1.2492 to find P.
P = $8805.64 (approx)
