a)
To solve: The given equation
a)

Answer to Problem 13STP
The value of width w is 26 feet.
Explanation of Solution
Given information:
It is given an equation
Concept used:
To solve given equation for variable w , first 36 will be subtracting from each side and then each side will be divided by 2.
Calculation:
On subtracting 36 each side,
Now on dividing each side by 2,
Conclusion:
Thus, it is concluded that present width of yard is 26 feet.
b)
To calculate: Total fencing, if the value of width w is increased by 12 feet.
b)

Answer to Problem 13STP
Total length of new fencing after increasing the width by 12 feet is 112 feet.
Explanation of Solution
Given information:
It is given an equation
Concept used:
Get new width and put this value in above expression
Calculation:
On adding 12 feet in this current width, new width is 38 feet, so total length of new fencing,
Conclusion:
Thus,total length of new fencing is 112 feet.

(n - 1)!arrow_forwardAmy and Samiha have a hat that contains two playing cards, one ace and one king. They are playing a game where they randomly pick a card out of the hat four times, with replacement. Amy thinks that the probability of getting exactly two aces in four picks is equal to the probability of not getting exactly two aces in four picks. Samiha disagrees. She thinks that the probability of not getting exactly two aces is greater. The sample space of possible outcomes is listed below. A represents an ace, and K represents a king.
