Answer: 3/4

Step-by-step explanation:

Number of students in Jacob's homeroom = 20.

Number of students who bring their lunch to school = 5

Since the rest eat lunch in the cafeteria, the number of those who eats in the cafeteria will be:

= 20 - 5

= 15

Fraction that eats in the cafeteria will be: = 15/20 = 3/4

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.

6(x +8)

Factorising:

6x + 48

Take 6 as common, Therefore:

6(x +8)

Because:

6 * x = 6x

6 * 8 = 48

therefore:

6x + 48 = 6(x + 8)

an unopened can of iced tea contains 350 cubic centimeters of liquid. if the van is 5 inches long and has a .8 inch diameter, wh
MariettaO [177]

the can is 5 inches tall, so its height is 5 inches, so 3 inches off 5 inches that'd be 3/5.

the can has a diameter of 0.8 inches, meaning it has a radius of half that, or 0.4 inches.

if say the volume of iced-tea is V, how much is 3/5 of V?  well, is just their product.


\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=0.4\\ h=5 \end{cases}\implies V=\pi (0.4)^2(5)\implies V=0.8\pi \\\\\\ \stackrel{\textit{and 3/5 of that will be}}{\cfrac{3}{5}\cdot 0.8\pi }\implies V\approx \stackrel{in^3}{1.51}
