Will give brainliest an oil company fills 1 over 10 of a tank in 1 over 5 hour. at this rate, which expression can be used to determine how long will it take for the tank to fill completely? 1 over 5 ⋅ 10 hours 1 over 10 ⋅ 5 hours 1 over 5 ⋅ 1 over 10 hours 5 ⋅ 10 hours

Option A. 1 over 5. 10 hours

Step-by-step explanation:

This question can be solved by the unitary method.

∵ Oil company fills of a tank in the time = hurs

∴ Full tank can be filled in the time = hours.

=

Therefore, the expression that can be used to determine the time that it will take to fill the tank completely will be Option A.

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
