Lemur [1.5K]

Answer:

Value of h greater than 5.4 will make inequality false.

Step-by-step explanation:

This question is incomplete; here is the complete question.

The Jones family has saved a maximum of $750 for their family vacation to the beach. While planning the trip, they determine that the hotel will average $125 a night and tickets for scuba diving are $75. The inequality can be used to determine the number of nights the Jones family could spend at the hotel 750 ≥ 75 + 125h. What value of h does NOT make the inequality true?

From the given question,

Per night expense (expected) = $125

If Jones family stays in the hotel for 'h' days then total expenditure on stay = $125h

Charges for scuba diving = $75

Total charges for stay and scuba diving = $(125h + 75)

Since Jones family has saved $750 for the vacation trip so inequality representing the expenses will be,

125h + 75 ≤ 750

125h ≤ 675

h ≤ $\frac{675}{125}$

h ≤ 5.4

That means number of days for stay should be less than equal to 5.4

and any value of h greater than 5.4 will make the inequality false.

Find two consecutive whole numbers such that the sum of their squares is 221.

Law Incorporation [45]

$n^2+(n+1)^2=2n^2+2n+1=221$
$2n^2+2n=220$
$n^2+n=110$
$n^2+n-110=0$
$(n-10)(n+11)=0\implies n=10,n=-11$

But since $n$ must be a whole number, we ignore $n=-11$ . So the two integers are $n=10$ and $n+1=11$ .
