So Im not sure about the english here and 6 yards doesnt really make sense but given the info you gave me:
The length of the outside is 120+15*2 and the width of the outside is 6+15*2 so you get a perimeter of 150*2+36*2=372
Are you sure the 6 isnt supposed to be 60? That would make more sense...
Answer:
79.7°
Step-by-step explanation:
We resolve the speed of the plane into horizontal and vertical components respectively as 300cos75° and 300sin75° respectively. Since the wind blows due west at a speed of 25 miles per hour, its direction is horizontal and is given by 25cos180° = -25 mph. We now add both horizontal components to get the resultant horizontal component of the airplane's speed.
So 300cos75° mph + (-25 mph) = 77.646 - 25 = 52.646 mph.
The vertical component of its speed is 300sin75° since that's the only horizontal motion of the airplane. So the resultant vertical component of the airplane's speed is 300sin75° = 289.778 mph
The direction of the plane, Ф = tan⁻¹(vertical component of speed/horizontal component of speed)
Ф = tan⁻¹(289.778 mph/52.646 mph)
Ф = tan⁻¹(5.5043)
Ф = 79.7°
3*2 is 6 6*2 is 12 12*2 is 24 24*2 is 48 48*2 is 96 96*2 is 192 and 192*2 is 384
Answer: 1.75
Step-by-step explanation:
5.25 / 3 = 1.75
1.75 x 4 = 7
7 + 5.25 = 12.25
1.75 x 7 = 12.25
since they are the same answer it's right
