FALSE

To calculate the perimeter of a triangle, add the length of its sides. For example, if the sides of a triangle are a, b, and c, the perimeter of the triangle is P = a + b + c.

Since all three sides of the triangle are the same length, you can multiply the length of each side by 3 to get the perimeter.

To find the circumference of a circle, multiply the diameter of the circle by π (pi). The circumference can also be calculated by multiplying 2 x radius by pi (π = 3.14).

I'm so confused how do you expand brackets and ?
Bogdan [553]
Expanding brackets is just your book's way of saying to use the distributive property and then simplify to solve each equation.

I'll show the work for a and b and then the answers for the rest.

a. 

4(g + 5) - 4g 

Multiply each part inside the parentheses by 4

4g + 4(5) - 4g
4g + 20 - 4g

Now combine like terms to simplify the equation. In this case, the 4g and - 4g cancel each other out.

4g - 4g + 20
0 + 20
20

20 is your answer.

b.  

6(p + 4) + 2(p - 12)

Multiply each part of the first set of parentheses by 6 and the second set by 2

6p + 6(4) + 2p + 2(- 12)
6p + 24 + 2p - 24

Combine like terms

6p + 2p + 24 - 24
8p + 0
8p

8p is your answer

c. 6z

d. 3a + 8

e. 8a + 16 which simplifies 8(a + 2)

f. 32w + 16 which simplifies 16(2w + 1)

The data from a survey on the academic degrees earned by students in the United States in 2009 is shown below.
Viefleur [7K]

Answer:

0.23

Step-by-step explanation:

You are given the table

\begin{array}{cccc}\text{Degree}&\text{Male}&\text{Female}&\text{Total}\\\text{Associate}&298&489&787\\\text{Bachelor}&685&916&1,601\\\text{Master}&260&397&657\\\text{Professional}&47&45&92\\\text{Doctorate}&32&35&67\\\text{Total}&1,322&1,882&3,204\end{array}

Form this table

Number of associate male students = 298

Total number of male students = 1,322

Relative frequency of male students earning an associate’s degree among all the males earning any degree =\dfrac{298}{1,322}\approx 0.23
