Answer:
48 minutes
Step-by-step explanation:
Given that;
Rosalinda can line the football field in 80 minutes
Reggie can line the football field in 120 minutes
Lets assume that if they work together, they will take T minutes to line the football field
Hence;
Thus in 1 minute, Rosalina can line 1/80 of the field where as Reggie can line 1/120 of the field

The sum of the two fractions will represent the size of the field that can be lined in 1 minute.

The reciprocal of the sum of the two fractions will represent the time taken for both Rosalinda and Reggie to line the field.
Answer ; It will take them 48 minutes for them to line the football field
Step-by-step explanation:
step 1 .simply N/6 equation at the end of step 1 is (7+n/6)-1=0
step 2. rewrite the whole as an equivalent fraction 7=7/1=7.6/6
How sad, that you didn't include the list of choices.
The volume of the cone is (1/3) x (π) x (radius²) .
The volume of the sphere is (4/3) x (π) x (radius³) .
So for this question, we're asked to find the quadrant in which the angle of data lies and were given to conditions were given. Sign of data is less than zero, and we're given that tangent of data is also less than zero. Now I have an acronym to remember which Trig functions air positive in each quadrant. . And in the first quadrant we have that all the trig functions are positive. In the second quadrant, we have that sign and co seeking are positive. And the third quadrant we have tangent and co tangent are positive. And in the final quadrant, Fourth Quadrant we have co sign and seeking are positive. So our first condition says the sign of data is less than zero. Of course, that means it's negative, so it cannot be quadrant one or quadrant two. It can't be those because here in Quadrant one, we have that all the trick functions air positive and the second quadrant we have that sign. If data is a positive, so we're between Squadron three and quadrant four now. The second condition says the tangent of data is also less than zero now in Quadrant three. We have that tangent of data is positive, so it cannot be quadrant three, so our r final answer is quadrant four, where co sign and seek in are positive.
Answer:
c. 500
Step-by-step explanation:
125+125=250
250+125=375
375+125=500
