Answer:

Let's talk about ratios and proportions. When we talk about the speed of a car or an airplane we measure it in miles per hour. This is called a rate and is a type of ratio. A ratio is a way to compare two quantities by using division as in miles per hour where we compare miles and hours.

A ratio can be written in three different ways and all are read as "the ratio of x to y"

xtoy

x:y

xy

A proportion on the other hand is an equation that says that two ratios are equivalent. For instance if one package of cookie mix results in 20 cookies than that would be the same as to say that two packages will result in 40 cookies.

201=402

A proportion is read as "x is to y as z is to w"

xy=zwwherey,w≠0

If one number in a proportion is unknown you can find that number by solving the proportion.

Evaluate the limit 12n^3 - 2n^2 + 9 / 4n^3
geniusboy [140]

Answer:

3

Step-by-step explanation:

Evaluate the limit n - > ∞ 12n^3 - 2n^2 + 9 / 4n^3

Divide the expression by the highest power of n to have

limit n - > ∞ 12n³/n³ - 2n²/n³ + 9/n³ / 4n³/n³

= limit n -  > ∞12 - 2/n + 9/n³ / 4

Substitute the value of n

= 12 - 2/∞ + 9/∞³ / 4

Since a/∞ = 0

The expression becomes;

= 12 - 0+ 0/4

= 12/4

= 3

Hence the required limit is 3

If the area is 1808.64 what is the circumference
Dafna1 [17]
Area of circle = πr²

Find radius:
πr² = 1808.64
r² = 1808.64 ÷ π
r² = 575.71
r = √575.71
r = 23.99 units

Find Circumference:
Circumference = 2πr
Circumference = 2π (23.99)
Circumference = 150.76 units

Answer: Circumference = 150.76 units
