less than 3 is a 1 or 2

probability of 1    or   probability of 2

        1/8               +            1/8

                        2/8

                    =  1/4

Answer: 1/4  = .25

SOVA2 [1]
The perimeter of the figure or polygon is calculated by adding up the value of the sides. In this case,
 
           Perimeter = 2 (length + width)

We are given that the length is equal to 525 ft.
           1205 = (2)(525 + y)

The value of y from the equation is 77.5 ft. 

Answer: 77.5 ft

Find the value of x.
konstantin123 [22]

Answer:

x= 37.5°

Step-by-step explanation:

∠CBD

= 180° -75° (adj. ∠s on a str. line)

= 105°

∠BCD= ∠BDC (base ∠s of isos. △BCD)

∠BCD= x

∠BCD +∠BDC +∠CBD= 180° (∠ sum of △BCD)

x +x +105°= 180°

2x= 180° -105°

2x= 75°

x= 37.5°

<u>Alternative</u><u> </u><u>working</u><u>:</u>

∠BDA= (180° -75°) ÷2 (base ∠s of isos. △ABD)

∠BDA= 52.5°

∠BDA +∠BDC= 90°

52.5° +x= 90°

x= 90° -52.5°

x= 37.5°

Explain how you can determine whether or not a number is rational
Darina [25.2K]
The easiest way to tell if a number is rational or not is to attempt to express it as a fraction. If you can, then the number is rational. If not, then the number is irrational. All integers are rational numbers, because they can be written as a fraction (for example, the integer 8 = 8/1). But numbers like pi or sqrt(2) cannot be written as a fraction and are not rational.
