Ice is placed around a bowl of water to lower the temperature. the equation d=−75t+22 d 7 5 t 22 shows the time, t, measured in minutes and temperature, d, measured in degrees celsius. which statement is correct? (a. the temperature of the water decreases 5°c 5 c every 7 minutes.) (b. the temperature of the water increases 7°c 7 c every 5 minutes.) (c. the temperature of the ice that is around the bowl is 22°c 22 c .) (d. before cooling begins, the temperature of the water is 22°c 22 c .)

D

Step-by-step explanation:

D=-75t+22

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

its 50 miles away from the starting point
