Answer:
24 times
Step-by-step explanation:
It is given that :
The length of the side of square A = 5 inches
The length of the side of square B = 25 inches
Therefore, area of square A = 5 x 5
= 25 square inches
Similarly, area of square B = 25 x 25
= 625 square inches
Therefore, number of times the square B is bigger than the square A is given by :
= 24
Thus the square B is 24 times bigger than square A
Gasoline is a homogeneous mixture.
The correct answer is b. gasoline.

Step-by-step explanation:
8 litres (amount of 20% solution needed) and 7 litres for (amount of 50% solution needed)
<u>Step-by-step explanation:</u>
Let consider ‘x’ for 20% acid solution and (15 – x) for 50% acid solution. And so, the equation would be as below,
20% in x + 50% in (15 – x) = 15 litres of 34%
Convert percentage values, we get
0.20(x) + 0.50 (15 – x) = 15 (0.34)
0.20 x + 7.5 – 0.50 x = 5.1
-0.3 x + 7.5 = 5.1
0.3 x = 7.5 – 5.1
0.3 x = 2.4
Apply ‘x = 8’ value in (15 – x) we get,
15 – 8 = 7 litres
The value of 7 litres for (amount of 50% solution needed)
