Answer:
If the homeowner helps the roofer it will take 4 days to roof the house.
Step-by-step explanation:
Given that a homeowner estimates that it will take 11 days to roof his house, while a professional roofer estimates that he could roof the house in 6 days, to determine how long it will take if the homeowner helps the roofer the following calculation must be done:
1/6 + 1/11 = X
0.1666666 + 0.09090909 = X
0.25 = X
1/4 = X
Therefore, if the homeowner helps the roofer it will take 4 days to roof the house.
1 liter = 1000 milliliters.
To work out how much is in the pitcher, we do 1000 x 3 because there are 3 liters, and each liter is 1000ml.
Therefore, the answer is 3000 milliliters.
1.4 as a decimal. 1.4=140
You need to make the same denominator for last fraction
The distance of the image from the lens V=22.5cm and the height of the image h=6.25cm.
<h3>What will be the distance and the height of the image placed in front of the convex lens?</h3>
It is given that
Hieght of an object H = 5cm
Distance of an object =18cm
Focal lenght of lens = 10cm
As we know that the lens formula is given by
so now
Now to find the height of the image
Thus the distance of the image from the lens is V=22.5cm and the height of the image h=6.25cm.
