................

After solving the equations, the distance between two airplanes after two hours will be equal to 861.21 miles.

The speed of an entity, which is a scalar quantity in regular usage and kinematics, can be defined as the size of the change in direction per unit of time or the size of the change in position over time for an object. The initial speed is the upper limit of maximum pace as the duration of a time interval gets closer to zero.

Assume that both the planes are on similar point A at the start.

Assume that x is the 325 mph flying object.

Consequently, it would have traveled a distance of after two hours of 325 × 2 = 650 miles.

Let B represent the location of the plane two hours later.

That means AB = 650 miles

Assume that y is the 300 mph flying object.

It would have traveled a distance of two hours = 300×2=600 miles.

After two hours, let C represent the location of the second plane.

This means AC=600 miles

After two hours, BC separates the two aircraft.

So, the angle between their paths is 87°.

Cos A = (AC² + AB² - AC²)/(2(AC)(AB))

cos 87 = (600² - 650² - AC²)/(2 × 600 × 500)

40822.04 = 782500 - AC²

AC² = 782500 - 4082204

AC = 861.21 miles.

Answer:

C)1 h 05 min

Step-by-step explanation:

If departure time of a train is 03 45 and arrival time is 04 50. What will be the journey time? * A)1 h 20 min B)1 h 10 min C)1 h 05 min

The journey time is calculated as:

Arrival time - Departure time

= 04:50 - 03:45

= 01:05

Therefore, the journey time = 1 hr 05 minutes

Answer:

100 yards

346.6 yards

There are two constants, across the level of competition: 120 yards (360 feet) of length and 53 1/3 yards (160 feet) of width. The playing field is 100 yards long, with a 10-yard-deep end zone on each side. In total, a football field covers 57,600 square feet, or the equivalent of 1.32 acres.

Hey there! Your answer to this problem is 2160..

Explanantion:

Since every car Sara sells, she gets 9% of the commission, this means that at the last few step, we would have to give 9% of the total cost to Sara.

If 100% is 20,000, then 50% would be 10,000. But we have to find the cost of 20%. So what we would actually be doing is multiplying 20 with 0.01. 20x0.01 is 0.2 or 0.20.

Then you add the 4,000 to the 20,000 because it states, “the next day, they sold the car 20% more than they paid. This means that you’ll have to add it. 20,000 plus 4000 would be 24,000. So 24,000 would be the cost of the car they sold.

However they didn’t wanna know the cost of the car, they wanted to know how much Sara would get. So you would have to take 9% of the cost of the cost which would be 2,160.

Final result: $2,160

Answer: x = 2

Step-by-step explanation: the interior angles of a rhombus add to 360 degrees and since half of 360 is 180, create the equation 130 + (36 +7x) and set it equal to 180. when solved 130 + (36 +7x) = 180 you get x =2

answer

1st rearrange the terms. then subtract 36 in both sides.then you will get 94=7x then simplify  by dividing by 7. then you will get 13.4285714286. which if you round up maybe its 94/7.

Answer: 2 11/24

Step-by-step explanation:

How many hours does the plane save?

Time taken for the train = 5 1/8

Time taken for the plane = 2 2/3

The number of hours saved will then be:

= 5 1/8 - 2 2/3

Let the lowest common multiple be 24

= 5 3/24 - 2 16/24

= 2 11/24

The number of hours saved by the plane will be 2 11/24

Answer: B: 11

Step-by-step explanation:

Just to the quiz for it

An equation is formed of two equal expressions. The number of players going to the tournament is 11.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Since the cost of the van is fixed, therefore, 231. Thus, the two equations can be written as,

Solving the above two equations we will get,

Px + 3P - 4.50x -13.5 = 231

3P - 4.50x - 13.5 = 0

3P - 4.50x = 13.5

3(231/x) - (4.50x) = 13.5

693 - 4.50x² = 13.5x

-4.50x² - 13.5x + 693 = 0

x² + 3x - 154 = 0

x = -14, 11

Since the number of members can not be negative, the number of players going to the tournament is 11.
