1. A quadrilateral has vertices (5, 3) (5,-1) (-1,3) and (-1,-1). What special quadrilateral is formed by connecting the midpoin
antiseptic1488 [7]

Answer:

1. Kite,

2. Kite.

Step-by-step explanation:

1. The quadrilateral form will have 2 equal  pairs of adjacent sides which is a kite.

2. Find the slope and length of the sides:-

slopes (9-6)/ 0-3) = -1

(6-1) / (3-0) = 5/3

(6-1) / (-3-0) = -5/3

(9-6)/(3) = 1

Lengths = sqrt(9 + 9) = sqrt18

sqrt(25 + 9) = sqrt34

sqrt (25 + 9) = sqrt34

sqrt (9 + 9) = sqrt18.

This is another kite.

An airplane flies with a constant speed of 620 miles per hour. How long will it take to
LekaFEV [45]

Answer:

30 minutes

Step-by-step explanation:

Alright lets start by laying out what the problem gives us :

A plane flies 620 mph.

It is asking how long it will take to travel 310 miles.

We need to give our answer in minutes or hours.

So lets take mph and look at the full meaning "Miles per hour"

An hour has 60 minutes in it.

So really it is saying miles per 60 minutes as well as miles per hour

So you could say the plane is traveling 620 miles every 60 minutes.

So now lets look at the number 310.

Just looking at it I can tell you that 310 looks very close to half of 620, in fact it is exactly half!

So lets divide the 620 mph by the 310 miles it is asking and we get 2! Proving that 310 is half of 620.

Alright now lets divide both the number of miles and number of minutes :

620 miles per 60 minutes

divided by 2 both miles and minutes

310 miles per 30 minutes

So this is your answer. After this you get that it would take 30 minutes to travel 310 miles in a plane going 620 miles per hour!

I hope this helps and I could help you understand it. :)

If you have any questions feel free to comment or dm me.
