ikadub [295]3 years ago
7 0

Answer:

36 cm^2.

Step-by-step explanation:

The area  is half the product of the lengths of its diagonals.

(PA)(LY) = (12cm)(6cm)

= 72 cm

72cm ÷2= 36 cm^2

Therefore the area is 36 cm^2

Find the midpoint of diagonal AC of ABCD
Vladimir79 [104]

Answer:

M= (1, 3)

Step-by-step explanation:

we have from the picture:

A = (-3,5)

C = (5, 1)

M = Midpoint

M =((x1+x2)/2), ((y1+y2)/2)

so we have:

x1= -3     y1 = 5

x2= 5     y2= 1

M= ((-3+5)/2) , ((5+1)/2)

M = ((2/2) , (6/2))

M= (1, 3)

Flying against the wind, a jet travels 2160 miles in 3 hours. Flying with the wind, same jet travels 6000 miles in 6 hours. What
marissa [1.9K]

Answer:

The velocity of jet in still air is  860miles/hour and velocity of wind is   140miles/hour.

Step-by-step explanation:

Let x be the rate of the jet in still air and y be the rate of the wind.

Given:

Velocity against wind, a jet travels 2160 miles in 3 hours.

Velocity against wind =\frac{2160}{3} = 720 miles/hour

Flying with the wind, same jet travels 6000 miles in 6 hours.

Flying with the wind =\frac{6000}{6} = 1000 miles/hour

As such its velocity against wind is  x-y

and with wind is   x+y therefore

x-y=720------------(1)

x+y=1000---------------(2)

Adding equation 1 and 2.

2x=1720

x=\frac{1720}{2}

x=860

Put x value in equation 2

860+y=1000

y=1000-860

y=140

Hence velocity of jet in still air is  860miles/hour and velocity of wind is   140miles/hour.
