Answer:
see below
Step-by-step explanation:
a. The years between 65 and 40 is
65-40 = 25 years
Multiply the decrease by the number of years
.06 *25 = 1.5 cm decrease
Change to inches
1.5 cm * 1 inch/2.54 cm =.59 inches
She will decrease .59 inches
5 ft 7 inches - .59 inches
5 ft 6.41 inches
b 90 years - 40 years = 50 years
50 * .06 =3 cm
Change to inches
3 cm * 1 inch/2.54 cm =1.18 inches
She will decrease 1.18 inches
Add this to her height now to get her height at 40
5 ft 1 inch + 1.18 inches = 5 ft 2.18 inches
