Answer:

The wind speed is 20 miles per hour.

Step-by-step explanation:

Speed = distance/time.

With the wind

230 + w = 400 / t where w is the speed of the wind.

Against the wind:

230 - w = 336/t

From the above equations:

t = 400/ (230 + w)

t = 336/ (230 - w) So:

400/ (230 + w) = 336/ (230 - w)

336(230 + w) = 400(230 - w)

77280 + 336w = 92000 - 400w

736w = 92000 - 77280 = 14720

w = 14720 / 736

w = 20.

Find the volume in cubic feet of the right rectangular prism pictured below

IgorLugansk [536]

We know that
2 3/8------> (8*2+3)/8-----> 19/8 ft
3 1/2-------> (3*2+1)/2-----> 7/2 ft
[volume of the rectangular prism]=(19/8)*(7/2)*(8)-------> 1064/16----> 133/2 ft³
133/2 ft³ -----> 66.5 ft³------> 66 1/2 ft³

the answer is 66 1/2 ft³

Linear Equations. Solve the equation 5 = 3y +6 using inverse operations.

agasfer [191]

Answer:

The value of $y=\frac{-1}{3}$ .

Step-by-step explanation:

Considering the equation

$5 = 3y +6$

To solve the equation $5 = 3y +6$ using inverse operations,

Subtracting 6 on both sides of the equation,

$5-6 = 3y +6-6$

Simplifying,

$-1 = 3y$

Dividing both sides by 3

$\frac{-1}{3} =\frac{3y}{3}$

$\frac{-1}{3} =y$

Switching both sides

$y=\frac{-1}{3}$

Therefore, the value of $y=\frac{-1}{3}$ .
