In a mechanic engineering school, the ratio
of female/male students is 1:6. There are
497 students in total, calculate how many
female students there are?
Select one:
O a. 75
O b.71
O c. 78
O d. 77

Correct b.  f = 71

Step-by-step explanation:

Given:

Let be female variable y

Let be male variable x

y : x = 1 : 6 ⇒ x = 6 y

x + y = 497

6 y + y = 497

7 y = 497

y = 497 / 7 = 71

y = 71 female

God is with you!!!

i say b hope this jdjdjdj

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
