See my response to your last post.
To find the change in temperature, subtract the initial temperature from the final temperature. In this case, the final temperature is 35.7° and the initial temperature is 48.2°.
So, the change in temperature is 35.7° - 48.2° = -12.5°.
This means that the temperature dropped by 12.5°.
Therefore, the correct answer is D: 12.5°.
To find the cost of 7 gallons of ice cream, we can set up a proportion using the given information.
Since Carlos bought 3 gallons of ice cream for $9.50, we can write the proportion as:
3/9.5 = 7/x, where x represents the cost of 7 gallons of ice cream.
Cross-multiplying, we get:
3x = 9.5 * 7
3x = 66.5
x = 66.5/3 = 22.17
Therefore, the correct proportion is B: 3/9.5 = x/7.
To find the total amount of money the concession stand earns for selling p pizzas, we need to multiply the number of pizzas sold (p) by the amount of money earned for each pizza ($2).
So, the expression that describes the total amount of money the concession stand earns for selling p pizzas is:
A: 2 x p.
This means that the concession stand earns $2 for each pizza it sells.
Therefore, the correct answer is A: 2 x p.
