Step-by-step explanation:
Shawn's living room is a square, so all four sides are the same length. Area of a square is A = s², and we know the area is 196 ft². If substitute this for A:
196 ft² = s²
Take square root of both sides:
s = √(196 ft²)
s = ±14 ft
Since measurements of lengths can't be negative, s must be +14 ft. So Shawn's living room is 14 ft x 14 ft.
When you have to divide a fraction, you have to invert the second fraction (4/7 becomes 7/4), and you then multiply the two fractions.
=2/5 ÷ 4/7
=2/5 * 7/4
Multiply the numerators on top
Multiply the denominators on bottom
=(2*7)/(5*4)
=14/20
Simplify by dividing 2 into top & bottom
=7/10
Hope this helps!! :)

Answer:
Step-by-step explanation:
Given:
Hairstylist schedule:
1/4 hour to trim a customer's hair
1/6 hour to style the customer's hair
Work per week:
2 × 1/3 hours per day
= 7/3 hours oer day
5 days a week
Hours in a week = 7/3 × 5
= 35/3 hours per week.
A customer must have hair styled and trimmed.
Total number of hours per customer = 1/4 + 1/6
= 5/12 hours per customer.
Therefore, 28 appointments can be nade each week.
Total number of hours per week = 5/12 × number of customers, n
35/3 = 5/12 n
n = 28 customers per week
