Answer:

11 bottles

Step-by-step explanation:

make a proportion because if you're using the same rate proportions can show that it's equal

\frac{7}{90} = \frac{x}{140}

cross multiply

7 *140= 980

divide the answer by 90 to find x

980/90= 10.8

round to 11 because you can't have 10.8 bottles

an open concrete tank is internally 1m wide, 2m long and 1.5m deep, the concrete being 10cm thick. Calculate the capacity of the
mixer [17]
Capacity of tank in litres:

1x2x1.5=3m^3 or 3000 litres

Volume of concrete:

(0.1*1.5*1*2)+(0.1*1.5*2(0.1*2))*2)+(0.1*1.2*2.2)=0.3+0.66+0.264=1.224 m^3 of concrete

(Thickness x Depth x Width excluding the thickness of the wall x Two sides) + (Thickness x Depth x Length including the thickness of the wall on both sides x Two sides) + (Base slab dimensions)
