Answer:
The total amount of gas Ms. Smith used on the trip is $25.
Step-by-step explanation:
To solve this problem, we first must figure out how many gallons of gas Ms. Smith used on her trip. If she drove 700 miles and averaged 35 miles per gallon, if we divide 700 by 35 we can figure out how many gallons she used.
700/35 = 20
Thus, Ms. Smith used 20 gallons on her trip. Next, to figure out what the cost of the gasoline was, we must multiply the number of gallons (20) by the cost of gasoline per gallon ($1.25).
20 gallons * $1.25/gal = $25
Therefore, the cost of gasoline for the trip was $25.
Hope this helps!
A.
cannot be the power set of any set. Consult Cantor's theorem, which says that the cardinality of the power set of any set (even the empty set) is strictly greater than the cardinality of the set.
(No part b?)
c. Also not the power set of any set, because any power set must have
elements, where
is the cardinality of the original set. The cardinality of this set is 3, but there is no integer
such that
. This set would be a power set if
(that is, the set containing the empty set) were a member of it.
Given ---›
y = -3
&
y = x - 0.8
So,
=> x = y + 0.8
=> x = -3 + 0.8
=> x = -2.2
Therefore, the best approximation for the solution to this system of equations is = (–2.2, –3)
Answer: The answer is 3n + 2
Step-by-step explanation: You will have to combine like terms:
=−n + −4 + 4n + 6
=(−n + 4n) + (−4 + 6)
=3n + 2
First, you divide 58 bars by 4. The answer will be 14 boxes with 2 bars remaining in the box.
