Maureen tracks the range of outdoor temperatures over three days. she records the following information.

(picture attached)

which answer below expresses the intersection of the three days as an inequality in terms of temperature, t. (the intersection would be the temperatures they have in common.)

0 < t < 40

0 ≤ t ≤ 40

-23 ≤ t ≤ 50

-23 < t < 50

The answer is:

The correct option is the third option;

To find which of the options expresses the intersection of the three days as an inequality in terms of temperature "t" we need to find an inequality which starts at the lowest temperature (greater or equal) and finish at the highest temperature (less or equal).

So, we have that the lowest temperature is -23°F and the highest temperature is 50°F, there are two options for that range, but we need to consider that the temperature will range from -23° to 50°, so, the correct option is the third option;

We can see that the inequality express that the temperature will range from -23°F being greater or equal than that, to 50°F being less or equal than that.

Have a nice day!

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
