A rectangular piece of plywood has a diagonal that measures three feet more than the width. The length of the plywood is three t

Advocard [28]

Answer:

The length of the plywood diagonal is $4.387\ units$

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

$d=\sqrt{x^{2}+y^{2} }$ -----> equation A

$d=y+3$ ----> equation B

$x=3y$ -----> equation C

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

$(y+3)=\sqrt{(3y)^{2}+y^{2}}$

squared both sides

$(y+3)^{2}=10y^{2}\\ \\y^{2}+6y+9=10y^{2}\\ \\9y^{2}-6y-9=0$

Solve the quadratic equation by graphing

The solution is $y=1.387\ units$

see the attached figure

Find the value of d

$d=y+3$ ----- > $d=1.387+3=4.387\ units$

It would take Steve 4 hours to paint a room. If Andre helps him, they can finish painting the room in 3 hours. How long would An

Lapatulllka [165]

Answer:

12 hours

Step-by-step explanation:

Given data

Steve= 4 hours

Steve and Andrea= 3 hours

Applying the combined work formula

1/A+1/B= 1/T

1/4+1/B= 1/3

solve for B

B+4/4B= 1/3

cross multiply

3(B+4)= 4B

3B+12= 4B

12= 4B-3B

12= B

Hence Andrea will spend 12 hours alone
