Answer:
Subtract
Step-by-step explanation:
According to the Quotient Of Powers Property to divide two powers with the same base, you subtract the exponents.
Ex: 9^12 - 9^9 = 9^3

Answer: 0.48</h3>
==========================================================
Explanation:
Define the events
- D = person orders a drink
- H = person orders a hamburger
- F = person orders fries
The given probabilities are
- P(D) = 0.90
- P(H) = 0.60
- P(F) = 0.50
- P(F given H) = 0.80
The notation "P(F given H)" refers to conditional probability. If we know the person ordered a burger, then it changes the P(F) from 0.50 to 0.80; hence the events H and F are dependent.
----------------------
We want to find the value of P(H and F), which is the same as P(F and H)
We can use the conditional probability formula
P(F given H) = P(F and H)/P(H)
P(H)*P(F given H) = P(F and H)
P(F and H) = P(H)*P(F given H)
P(F and H) = 0.60*0.80
P(F and H) = 0.48
There's a 48% chance someone orders a burger and fries.
<span>(1 gallon)/(20 miles) = (x gallons)/(180 miles)
1/20 = x/180
1*180 = 20x
180 = 20x
20x = 180
</span><span>x = 180/20
x = 9
It takes 9 gallons of gas to drive 180 miles
(9 gallons)*(3.98 dollars/1 gallon) = 9*3.98 dollars = 35.82
Round to the nearest dollar: 35.82 ---> 36
It costs $36 to travel 180 miles</span>
Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)
