Daniel [21]
<h3><u>The two inequalities are:</u></h3>

a\geq 200\\\\5a + 2.50c\leq 1500

<h3><u>Solution:</u></h3>

Let "a" be the number of adult sized t shirts

Let "c" be the number of child sized t shirts

Given that,

Each Adult sized t shirts = $ 5

Each child sized t shirts = $ 2.50

<h3><u>Jerome need at least 200 adults t-shirt</u></h3>

Therefore,

a\geq 200

Here, we used "greater than or equal to" symbol, since he needs atleast 200 adult t-shirts

<h3><u>Jerome will spend no more than $1500 on t-shirt</u></h3>

Therefore,

5a + 2.50c\leq 1500

Here we used, "less than or equal to" symbol, since he will not spend more than 1500

Nataliya [291]

Answer:

Given the total area of the U.S. = 3.79 million square miles

The area of Alaska = 0.67 million square miles

Step-by-step explanation:

We have given the area of the United States and the area of Alaska. Since Alaska is a part of the United States so the area of Alaska is already included in the given area of the U.S.

Thus to find the probability that the meteor will hit Alaska can be calculated by dividing the area of Alaska from the area of the U.S.

The probability to hit the Alaska  = 0.67 / 3.79

The probability to hit the Alaska  = 0.1767
