AREA = 4,850
Step-by-step explanation:
split into two pieces
formula for triangles- base x height divided by 2
20 x 50 = 100 / 2 = 50
(130 - 50 = 80)
80 x 120 = 9,600 / 2 = 4,800
add...
4,800 + 50 = 4,850
The time it will take to fill the vat if both pipes are left open is = 4.3 hours
<h3>Calculation of time taken to fill vat</h3>
The number of pipes a vat has = 2
The time it takes the inlet pipe to fill the vat = 3hrs
The time it takes the outlet pipe to empty the vat= 10hrs
Therefore, the time it will take to fill the vat if both pipes are left open is;
1/t = 1/3-1/10
1/t = 7/30
Make t the subject of formula,
t = 30/7
t= 4.3 hours
