Solve for n.<br> d=5m +11n

Serhud [2]

Answer:

$n=-\frac{5m}{11} +\frac{d}{11}$ or $n=\frac{d}{11}-\frac{5m}{11}$

Step-by-step explanation:

d=5m+11n

-11n=5m-d

11n=-5m+d

$n=-\frac{5m}{11} +\frac{d}{11}$

It won't be wrong if you also put $n=\frac{d}{11}-\frac{5m}{11}$

A circle of radius 10cm had a hole cut out of its centre to form a ring. Find the radius of the hole if the remaining area is 50

valentina_108 [34]

Answer:

7.07cm

Step-by-step explanation:

A=πr2

= 100 π

= 314.159265359/2 (squared)

50% = 157.07963268cm ^2

We look for radius in the area formula

A=πr2

(A / π ) = 157.07963268/ 3.14159265359 = √50 = 7.07106781187

We do not need to half this as already has been squared.
