The air quality index, or aqi, measures how polluted the air is in your city and assigns a number based on the quality of the ai
makkiz [27]

The number of days in which the air quality index exceed 100 in the year 1988 is 75 days. Then the correct option is B.

<h3>What is a function?</h3>

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

The air quality index (AQI) is given by the function.

\rm n = 1.76t^2-13.32 +41

Where n be the number of days the AQI exceeds 100 in a given year.

For \rm t = -2, then we have

\rm n = 1.76(-2)^2-13.32(-2) +41\\\\n = 7.04+26.64+41\\\\n = 74.68 \approx 75

More about the function link is given below.

What is a fraction pair that is equivalent to 2/15 and 4/9, and in which both fractions have a
Vesnalui [34]

Answer:

  6/45 and 20/45

Step-by-step explanation:

The least common denominator is the least common multiple (LCM) of 9 and 15.

The factors of those numbers are ...

  9 = 3·3

  15 = 3·5

The LCM is the product of the unique factors to their highest powers:

  3·3·5 = 45

__

To make 2/15 have a denominator of 45, we need to multiply by 3/3:

  2/15·3/3 = 6/45

To make 4/9 have a denominator of 45, we need to multiply by 5/5:

  4/9·5/5 = 20/45

The desired fraction pair is 6/45 and 20/45.
