Answer:
19.2 but if u cant us decimals take out 2
Step-by-step explanation:
you time 8 by 12 and then divide it by 5
Answer:
can't understand your question
For this question you can put 7 for x and 10 for y.
Then solve 3x + 4y:
3(7) + 4(10) = 21 + 40 = 61
so now you can divide it by 2:
61/2 = 30.5 :)))
I hope this is helpful
have a nice day
(0,-4)(6,2)
slope = (2 - (-4) / (6 - 0) = 6/6 = 1
y = mx + b
slope(m) = 1
(0,-4)..x = 0 and y = 4
sub and find b
4 = 1(0) + b
4 = b
equation is : y = x + 4...or x - y = -4
or y + 4 = 6(x - 0) ...or y - 2 = 6(x - 6)
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
