Answer:

The answer to your question is:

a) G) 60 miles / 6 hours = 10 mi/h, this is the right answer

b) rate = 3/16 mi/h

Step-by-step explanation:

F) 8 miles / 16 hours = 1/2 mi/h, then this is not the answer

G) 60 miles / 6 hours = 10 mi/h, this is the right answer

H) 48 miles / 12 hours = 4 mi/h, then this option is wrong

I) 0 miles / 17 hours = 0 mi/h, then this option is wrong

rate = 3 miles/16 min = 3/16 mi/h

SOS WHAT IS THE SQUARE ROOT OF 144/256?

tangare [24]

The square root is $\sqrt{\frac{144}{256}} = \frac{3}{4}$ Just square the top and bottom of the fraction. $\sqrt{144} = 12$ and $\sqrt{256} = 16$ so we have 12/16 and then we reduce to 3/4

Answer:

y (plane speed) 400 miles/hr

x (wind speed) 40 miles/hr

Step-by-step explanation:

going into the wind make the plane flew 5,5 hours to get 1980 miles, implies the real travel speed was

1980 / 5,5 = 360 miles/hours, and at the same time is the result of:

speed plane (y) in direction A to B plus wind speed (x) in direction B to A. Notice opposites direction speed, so we have:

y + (-x) = 360 (1)

The return fly took 4,5 hours so 1980/4,5 = 440 miles/ hours as the result

Y + x = 440 (2)

We have a two equation with two variables system, It could be solved for any of the procedures. We will use the substitution method.

From equation (1) y + (-x) = 360 y - x = 360 y = 360 + x (1)

In the second equation

y + x = 440 then we replace y for its value as function of x

(360 + x ) + x = 440

Solving for x 360 + 2x = 440 or 2x = 440 – 360

x (440 - 360)/2

x = 40 miles/hr

X (wind speed ) = 40 miles/hr

And replacing the value of x in eq. (1) y = 360 + 40 = 400

Y (plane speed) = 400 miles /hr

Can you guys help please im so confused

marissa [1.9K]

Answer:

a) see below

b) 40x20 meters

Step-by-step explanation:

Write down what you know:

- The area of the enclosure is length*width, so

$A = x \cdot y$

- The length of the fencing is 80 meters, so

$2y + x = 80$

Now we have to combine these two equations above, and get rid of y in the process.

First rewrite the second as:

$y = 40 - \frac12 x$

Then substitute for y in the first:

$A = x (40 - \frac12 x) = 40x - \frac12x^2$

b) To maximize A, find the zero of the first derivative:

$A'(x) = 40 - x = 0 \implies x=40$

So y = (80-40)/2 = 20 meters.
