24) All percents are numbers with the decimal moved 2 to the right. So if you have 275%, move the decimal to the left twice to get a factor of 2.75. that means that the puppy is 2.75 times heavier at 4 months than it was at 2 months. Since you need the answer as a mixed fraction, your answer is;
2.75=2+\frac{3}{4}=2~\frac{3}{4}

28) If 6 of 75 trees are 30+ feet tall and you need to know how many are under, subtract 6 from 75 to get (75 - 6) = 69 trees under 30ft tall.
You're looking for the percent of trees under 30ft tall, so divide the number of trees <30ft by the total number of trees to get;
\frac{69}{75}= .92
Move the decimal 2 to the right to get 92%.
Your answer is that 92% of trees is under 30ft.

How do you simplify the expression (s+t)3
bonufazy [111]

Answer:

3s + 3t

Step-by-step explanation:

To simplify this expression, all you need to do is distribute the 3, which means you basically multiply whatever is in the parentheses by 3:

(s + t) * 3 =

3s + 3t

And that is the simplified form for this expression.

Hope this helps :)

The formula for the area, a, of a regular polygon in terms of the perimeter of the polygon, p, and the length of the apothem, a,
kotykmax [81]

The equivalent equation that can express the area of a polygon in terms of the perimeter is given by A = P/2

<h3>What is Polygon: </h3>

A closed, two-dimensional object composed of straight lines is called a polygon. Typically names of polygons are based on the polygon's number of sides Like triangles, rectangles, pentagons, etc.  

<h3>Apothem of a polygon: </h3>

a line segment connecting the midpoint of a side to the center of a regular polygon is known as the Apothem of a polygon.

The area of a polygon with Apothem is given by

<h3>          Area = 1/2 × perimeter × apothem </h3>

Here given that

Number of sides of Polygon = 5 sides

Let P be the perimeter

Given the length of the Apothem = a  

By the given formula,

Area of the Polygon, A = (1/2) [P][a]

=> A = P/2                      

Therefore,

The equivalent equation that can express the area of a polygon in terms of the perimeter is given by A = P/2
