klasskru [66]

Answer:

see explanation

Step-by-step explanation:

Let c represent the number of children, then

number of men = 4c and number of women = 2c

Sum the numbers of each and equate to 266

4c + 2c + c = 266, that is

7c = 266 ( divide both sides by 7 )

c = 38

Thus

4 × 38 = 152 and 2 × 38 = 76

The group consists of 38 children, 152 men and 76 women

Akiko has a mass of 55kg how much does Akiko weight? Akiko climbs a flight of six steps each 20cm high how much work does she do

Masteriza [31]

Work= forcexdistance
force=55x10(or 9.8 depending on which gravitational field strength you use)
force= 550N
work = 550x0.2
work= 110J
six steps=110x6=660J
