Asprinter can run 279 feet in 9 seconds fine the sprinters unit rate of feet per sec

Hi there!

In order to answer your question, you'll need to use the cross product method:

279 feet → 9 seconds

X feet     → 1 second

(279 × 1) ÷ 9 = X feet

279 ÷ 9 = X feet

31 = X feet

Your answer is: The sprinter's unit rate of speed is 31 feet per second.

There you go! I really hope this helped, if there's anything just let me know! :)

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

you never say the total so we cant find the percentage used for petrol
