Answer:
number of gallons of water the family will use every morning = 50 gallons
Step-by-step explanation:
Every minutes 2.5 gallons of water flows from the shower . The amount of water disperse by the shower for every 1 minutes is 2.5 gallons. The family using the shower are 4 in numbers . And each of them spend on average of 5 minutes showering .
Let us find how many gallons of water will flow for 5 minutes since family member spent an average of 5 minutes bathing every morning/. Therefore,
2.5 gallons = 1 minutes
? gallons = 5 minutes
cross multiply
number of gallons of water each family member uses every morning = 2.5 × 5 = 12.5 gallons
They are 4 family members in number since each person uses 12.5 gallons of water , 4 of them will use 4 × 12.5 = 50 gallons
Hello there. To solve this question, we need to remember some properties on powers.
(-25)^(-4) * (5^(-3))^(-2)
To start, remember a^(-n) = 1/a^n, for a not equal to 0. Also, (ab)^n = a^n * b^n and (a^b)^c = a^(b*c)
Such that we have:
(-1)^(-4) * 25^(-4) * 5^((-3)*(-2))
1/(-1)^4 * (5^2)^(-4) * 5^6
Since (-1)^4 is equal to 1, we get:
5^(2*(-4)) * 5^6
5^(-8) * 5^6
Knowing that a^b * a^c = a^(b + c), we get:
5^(-8+6)
5^(-2)
Applying the first rule, we get:
1/5^2
1/25.
