The question says the machine uses up m gallons of oil each hour on weekends.
This means that if the machine works for 24 hours each day, it implies that:
There are only two days on weekends i.e. Saturday and Sunday.
This means that if the amount of oil used in 1 day in the weekend is 24m, then we can say:
Saturday: oil used is 24m
Sunday: oil used is 24m
Total oil used during the weekend is:
Answer:
490 pounds
Step-by-step explanation:
Peppermint hard candy costs $4.40 per pound, and Cinnamon hard candy costs $5.40 per pound.
If we mix the in x : y ratio respectively then the mixture costs $5.10 per pound.
Therefore, we can write
⇒ 0.3y = 0.7x
⇒
Now, if the candy store has 210 pounds of Peppermint hard candy, then Cinnamon hard candy required for making the mix is pounds. (Answer)
When you divide same numbers with exponents you would subtract the exponent: a^2/a^1 = a^(2-1) = a
Therefore: 6^-3/6^5 = 6^(-3-5) = 6^-8
Which is also 1/6^8
Solution: C
Answer:
Step-by-step explanation:
They already said the domain of f(x) is x≥0.
The smallest value of f(x) is f(0) = 9.
Range of f(x) is y≥9.
The radicand of a square root must be non-negative, so the domain of f⁻¹(x) is x≥9.
The range is y≥0.
