Answer:
length: 120 feet
width: 80 feet
area: 9600 feet^2
Step-by-step explanation:
since the scale is 1 inch:10 feet:
to find the actual length, we would multiply 12 by 10, since 1 inch would be 10 feet and the length in the floor plan is 12 inches:
length = 12*10=120
the length of the actual room is 120 feet.
to find the actual width, we would multiply 8 by 10, for the same reasons i explained for the length:
width = 8*10=80
the width of the actual room is 80 feet.
to find the area, we would multiply length by the width:
80*120=9600 square feet.
Answer:
10 days
Step-by-step explanation:
Mogaka and Ondiso working together can do a piece of job in 6 days. Mogaka working alone takes 5 days longer than Ondiso. How many days does it take Ondiso to do the work alone?
Let us represent :
The number of days
Mogaka worked alone = x
Ondiso worked alone = y
Total days worked together = T
Mogaka and Ondiso working together can do a piece of job in 6 days.
Hence,
1/x + 1/y = 1/T
Mogaka working alone takes 5 days longer than Ondiso.
x = y + 5
Therefore:
1/y + 5 + 1/y = 1/6
Multiply all through by (y+5)(y)
= y + y + 5 = (y+5)(y)/6
= 2y + 5/1 = (y+5)(y)/6
Cross Multiply
6( 2y + 5) = (y+5)(y)
12y + 30 = y² + 5y
= y² + 5y - 12y - 30 = 0
= y² - 7y - 30 = 0
Factorise
= y² +3y - 10y - 30 = 0
y(y + 3) - 10(y + 3) = 0
(y + 3)(y -10)= 0
y + 3 = 0, y = -3
y - 10 = 0
y = 10 days
Note that
The number of days Ondiso worked alone = y
Hence, it takes 10 days for Ondiso to work alone
