Answer:
50 hours
Step-by-step explanation:
Given that :
Painter can paint 2 small rooms and a balcony on 50 hours
Small room takes twice as long to paint as a balcony
Let :
Time taken to paint balcony = t
Time taken to paint small room = 2t
t + 2(2t) = 50
t + 4t = 50
5t = 50
t = 10
how long will it take him to paint 1 small room plus 3 balconies?
1 small room = 2t
3 balconies = 3t
2t + 3t = 5t
5(10) = 50 hours
You want to calculate the ratio of 7 2/3 feet to 5 3/4 feet. The correct answer will not have units of measurement.
Convert 7 2/3 and 5 3/4 to improper fractions: 23/3 and 23/4.
What is the quotient of 23/3 to 23/4? It's the same as 1/3 to 1/4: (1/3)(4/1) = 4/3.
Multiply the constants first: 3×(-1.7)=-5.1 which is the coefficient.
Standard form is -5.1xy².
x 21
----- = -----
110 100
Cross multiplication:
110 x 21 / 100
= 23.1
