To make the second batch of punch go further Josie,
1 answer:
The ratio of fruit juice to lemonade in the second batch is 21:16
<h3>What are ratios?</h3>Ratios are denoted by the sign ":", and they are used to making comparison between units of different quantities
The ratio is given as:
Where:
- F represents the amount of fruit juice
- L represents the amount of lemonade
When 2 litres are added to the original amount of lemonade, the ratio becomes
Hence, the ratio of fruit juice to lemonade in the second batch is 21:16

Answer:
6.82
Step-by-step explanation:
By congruence of triangles, the radius r of the cone base when its height is 1 meter satisfies the relation
r/1 = 2.5/6
(See picture attached)
So, r = 0.4166 meters when the water is 1 meter high.
The volume of a cone with radius of the base = R is given by
So, the volume of water when it is 1 meter high is
One minute later, the height of the water is 1 meter + 30 centimeters = 1.30 mt
The radius now satisfies
r/1.3 = 2.5/6
and now the radius of the base is
r = 0.5416 mt
and the new volume of water is
So, the water is raising at a speed of
0.3071-0.1871 = 0.12
This speed equals the difference between the water being pumped and the water leaking,
So,
<em>0.12 = Speed of water being pumped -6.8 </em>
and
Speed of water being pumped = 6.8+0.12 = 6.82
