Two right triangles are similar. The legs of the smaller triangle have lengths of 3 and 4. The scale factor is 1:3. Find the length of the hypotenuse of the larger triangle. The length of the hypotenuse of the larger triangle is

15 units.

Step-by-step explanation:

The hypotenuse of the smaller triangle = sqrt (3^2 + 4^2)

= sqrt 25 = 5.

As the scale factor is 1:3 the hypotenuse of the larger triangle = 5 * 3

= 15.

b.-4 units

all you   do is count how many times you move

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
