Answer:
7.5 litres.
Step-by-step explanation:
Volume of water lost in 1 month = 2.5 * 10^-4 * 3 * 10^5
= 2.5 * 3 * 10^(-4+5)

= 7.5 litres (answer)
Answer:
14 children
Step-by-step explanation:
Half the children like pets and a quarter of the children do not, so another quarter does not have preference. Let x = total number of children, and we would have this equation.
0.25x = 7
x = 28
Since we are asked to give the number of children who like pets, 28/2 = 14 is the answer.

Answer:
x = 7
Step-by-step explanation:
The sum of interior angles is equal to 360°
9x - 4 + 8x + 2 + 13x + 30 + 19x - 11 = 360° add like terms
49x + 17 = 360 subtract 17 from both sides
49x = 343 divide both sides by 49
x = 7
replace x with the value we found to calculate each angle.
