A plane, initially traveling 150 mi./hr.
100 east of north, suddenly enters a
region where the wind is blowing at
50 mi./hr. from the southwest.
What is the plane's resultant direction?
[?]° compass heading
Round to the nearest hundredth.
Enter

Answers

Answer 1

Answer:

Resultant is 50 mi/hr in the north east direction

Step-by-step explanation:

Plane is traveling north east at 150 mi/hr.

Now a wind is blowing from the south west at 100 mi/hr.

Now, north east and south west are directly opposite directions and such the angle between the resultant speed of the plane in flight and the wind will be;

150 - 100 = 50 mi/hr

Since the north east speed is greater than the south east speed, then the direction will be north east.

Thus, resultant is 50 mi/hr in the north east direction

Step-by-step explanation:

Notice that there are no points on the graph for x ≤ 2 and x ≥ 5.  Or another way to look at it is that the x's are between 2 and 5, inclusive.

The domain is the set of possible x values.  Therefore,  2 ≤ x ≤ 5 is the set of  values for the domain

There is nothing in the problem statement that suggests this is a right triangle. Without knowing at least one angle, we cannot solve for a numerical value for the perimeter. The problem title suggests we're to leave the result in polynomial form.

Find the values of x and y. y=? x=? PLEASE HELP

Answers

Answer:

x=15.714

y=5.715

Step-by-step explanation:

Answer:

x=10, y=20

Step-by-step explanation:

okay so to find x, or the way I did it, we just have to look at the top, we know one line is 180 degrees, and we see three angles, 7x,90, and 20

so 90+20+7x=180

and:110+7x=180

therefore: 7x=70

and finally: x=10

To find y also isn't had if we just look at the blue and green lines we see they are intersecting and opposite angles in intersecting lines are congruent meaning they are the same. So we now know that:

5x+2y=90

and we know x=10

so 5x=50

meaning that: 50+2y=90

therefore: 2y=40

and in conclusion y=20

On a given day, Gavin made a total of $135 in commission and sold 12 more accessories than phones. Determine the number of phones sold and the number of accessories sold.

There were
____phones sold and
____ accessories sold.

Answers

Answer:

6 phones and 18 accessories

Step-by-step explanation:

12P + 3.50A = 135

A = 12 + P

12P + 3.50(12 + P) = 135,

12P + 42 +3.50P = 135

15.50P = 93

P = 6 phones

A = 12 + 6 = 18 accessories
