A bird leaves its nest and travels 20 miles per hour downwind for x hours. On the return trip, the bird travels 4 miles per hour
natali 33 [55]
We need to calculate a total TIME.  
Let the time required to cover distance d at 20 mph be x.  d is the ONE WAY distance, not the total distance traveled (which would be 2d).

Remember the formula d=rt:  the distance traveled equals the rate times the time.  Here, d = rx, and thus x = d/r  = d/(20mph)

Let's begin by recognizing  that       d(going) = d(returning)
Then                                            (20 mph)x   = 6 + (16 mph)x

                                                      (20 mph)x - (16 mph)x = 6 miles
Then:                                                    (4 mph)x = 6 miles
or:                                                             x = 1.5 hours

It takes the bird 1.5 hours at 20 mph to cover distance d, which is 30 miles.
Thus, the total time spent flying is 1.5 hours (going) and [1.5 hours + (6 miles)/(16 mph) returning:

                            1.5 hours + 1.5 hours + 0.375 hours = 3.375 hours total.

The total distance covered is 2d, or 2(30 miles) = 60 miles.

It took me a while and a lot of experimentation to arrive at these results.  Please, if my arguments here are not clear, ask questions.

By cutting away identical squares from each corner of a rectangular piece of cardboard and folding up the resulting flaps, an op
lozanna [386]

Answer:

1.81 inch by 8.38 inch by 6.38 inch

Smallest Value=1.81 inch

Largest Value=8.38 inch

Step-by-step explanation:

The cardboard is 12 in. long and 10 in. wide

Let the length of the square cut off=x

Length of the box=12-2x

Width of the box=10-2x

Height of the box=x

Volume of the box=lwh

V=x(12-2x)(10-2x)

The dimensions of the box that will yield maximum volume occurs at the point where the derivative of V=0.

V^{'}=4\,\left( 30 - 22\,x + 3\,x^{2}\right)

Thus:

4(30-22x+3x²)=0

Since 4≠0

3x²-22x+30=0

Solving for x using a calculator gives:

x=1.81 or x=5.52

x cannot be 5.52 inch since the width is 10 inch and removing 2(5.52) from the width gives a negative result.

When x=1.81 inch

Length of the box=12-2x=12-2(1.81)=8.38inch

Width of the box=10-2x=10-2(1.81)=6.38 inch

Therefore, the dimensions at which the Volume is maximum are: 1.81 inch by 8.38 inch by 6.38 inch

Bro this makes no sense can someone explain
pantera1 [17]

Answer:

x=110^o

Step-by-step explanation:

If AB = AD, then you have that triangle ABD is an isosceles triangle (it has two equal sides). If it is isosceles, then the angles opposite to angles those equal sides must be equal. Then angle ADB = 35^o. and by the property of all internal angles of a triangle have to add to 180^o, we get that:

x=180^o-35^o-35^o=110^o
