How
andrey2020 [161]

Answer: 7800

Step-by-step explanation:

As English alphabet has 26 letters.

So , Choices for First character in the code = 26

The choices for digits = 10  (From 0 to 9)

So , choices for second character = 10  (Middle two characters must be numbers)

choices for third character = 10            (Middle two characters must be numbers)

Choices for last character = 3   (the  last character must be a 1, 3, or 7)

By Fundamental principle of counting , the total number of four character codes can be generated =

(Choices for First character)x (choices for digits) x(choices for digits) x(Choices for last character)

= (26) (10)(10)(3) =7800

Hence, the total number of character codes can be generated= 7800

What is the value of x in the equation 4x + 8y =40 when y =0.8
Neko [114]
Y = 0.8

4x + 8y = 40

4x + 8*(0.8) = 40

4x + 6.4 = 40

4x = 40 - 6.4

4x = 33.6

x = 8.4

Determine the length of the unknown sides for the right triangle
alisha [4.7K]

Answer:

Below in bold.

Step-by-step explanation:

sin 66.4 = opposite side / hypotenuse

sin 66.4 = 21.3 / y

y = 21.3 / sin 66.4

y = 23.24.

tan 66.4 = 21.3 / x

x = 21.3 / tan 66.4

x = 9.31.
