Answer:
a.) 7/20
b.) 0.375
c.) 1/15
Step-by-step explanation:
a. 0.35 is out of 1, so to find 0.35 in fraction form: 35/100.
Simplify that down by dividing both top-bottom by 5 and you get 7/20
b. 1/8th of anything is 0.125, so 0.125(3) = 0.375. Alternatively you can use a calc to calculate the decimal.
c. Find the area of the rectangular carpet: 60m. Then find the area of the square rug: 4m
Find the fraction: 4/60
Simplify by dividing top-bottom by 4 and you get 1/15
Online you can look for fraction calculators that show the work :)

Answer:</h2><h2>
Length of the drainpipe = 700.7 cm</h2>
Step-by-step explanation:
Given a builder makes drainpipes that drop 1 cm over a horizontal distance of 30cm to prevent clogs. The ratio of the vertical drop to the horizontal distance covered is cm.
The angle of inclination,
tan(θ) =
θ = 1.9º
By trignometric ratio,
cos(θ) =
length of the drainpipe = =
length of the drainpipe = 700.7 cm
