If m(ny - xsquare) + n = 5n, find y when n = 4, x = 2, m = 6 and z = 8

z

y=5/3

Step-by-step explanation:

m(ny-x²)+n=5n

6(4y-2²)+4=5×4

6(4y-4)+4=20

4y-4=(20-4)/6

4y=16/6 + 4

4y=20/3

y=(20/3)/4

y=5/3

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19

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
