A stretch of highway that is 3 1/4 kilometers long has speed limit signs every 3/5 a kilometer. How many speed limit signs are on this stretch of highway?

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

the opening of this porabola is facing up

step-by-step explanation:

step-by-step explanation:

d would equal 12

1332.

this is because to get from 333 to 999 you multiply by 3, and you should do the same to the number of hours.

therefore you would do 444*3=1332
