A horse is prescribed 128 mg liquid for a fever. However the oral solution is at a dose of 160mg/5mL. How many mL should the horse receive?

The horse should receive 4 mL

Step-by-step explanation:

Prescribed amount = 128 mg

Amount of solution in 160 mg = 5 mL

Amount of solution in 1 mg = 5/160 mL

⇒ Amount of solution in 128 mg = 128 × 5/160 = 4 mL

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
