Arectangular piece of plywood has a diagonal that measures three feet more than the width. the length of the plywood is three times the width. what is the length of the plywood diagonal?

The length of the plywood diagonal is

Step-by-step explanation:

Let

x-----> the length of the rectangle

y----> the width of the rectangle

we know that

The diagonal of rectangle is equal to

-----> equation A

----> equation B

-----> equation C

substitute equation C and equation B in equation A and solve for y

squared both sides

Solve the quadratic equation by graphing

The solution is

see the attached figure

Find the value of d

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
