You can mow a lawn in 2 hours with a ride on mower and your friend can mow a lawn in 3 hours with a hand mower. how much time will it take if both mow the same lawn

Step-by-step explanation:

If you can mow a lawn in 2 hours, then you get 1/2 of the job done in 1 hour.

If your friend can mow the same lawn in 3 hours, then he can get 1/3 of the job done in 1 hour.

The equation for the time it would take for both of you to do the job together, then, is

where x is the number of hours it takes for both of you to do this job.  Get rid of the denominators to solve for x.  Do this by multiplying everything by the LCD, which is 6x.

which simplifies to

3x + 2x = 6 and

5x = 6

x = 6/5 or 1 1/5 hours

  or  

step-by-step explanation:

if the four friends split the cost, p, of the pizza evenly, then each friend pays one-fourth of the cost of the pizza.

the expression is   or  

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
