Answer:

5,964 people are under 18 , 400 people are aged 18 to 60  , 8,236 people are over 60

Step-by-step explanation:

42 , 600 x 14/100 = 5,964 people are under 18

42,600 x 2/3 = 28 , 400 people are aged 18 to 60

The remaining over 60 = 42 , 600 - (5,964 + 28400)

42,600 - 34,364 = 8,236 people are over 60

Suppose that the number of cars manufactured at an automobile plant varies jointly as the number of workers and the time they wo
Yanka [14]

Answer:

They'll build 66 cars in those conditions.

Step-by-step explanation:

In this case we can use a compounded rule of three to solve the problem. We need to set it up as shown bellow:

160 workers -> 32 cars -> 2 hours

220 workers -> x cars -> 3 hours

If the number of workers rise, then we expect the number of cars to rise aswel, so they're directly proportional. If the number of hours worked increase we can expect the number of cars to increase aswell, so they're directly proportional. We can now set the fractions:

(160*2)/(220*3) = 32/x

320/660 = 32/x

x = (32*660/320) = 66 cars

They'll build 66 cars in those conditions.

HURRY PLEASE
DerKrebs [107]

Answer:

AD = 6.76 inches

Step-by-step explanation:

Taking the triangle ABC:

tan 45° = AB/BC

1 = AB/BC

AB = BC = 16 in

Taking the triangle DBC:

tan 30° = DB/BC

DB = BC * tan 30°

DB = 16 * tan 30°

DB = 9.24 in

Given that AD + DB = AB, then

AD =  AB - DB

AD = 16 - 9.24 = 6.76 inches
