y+z=10

x+z=8

x+y=12

(y+z)-(x+z)=10-8

y-x=2

y+x=12

solve simultaneously

x=5, y=7

then substitute to get z=3

hence xyz=573

Find perimeter of a circle frm whch a circle has been cutt off?

TEA [102]

Answer:

To find the perimeter, you actually need to find the circumference of a circle.

Step-by-step explanation:

The formula to find the circumference is:

C= 2 pi times r

The r is the radius of the circle. The 2 stays the same. If you have the radius then you are fine.

E.g. If you have a circle and you're given that the radius the distance from the center to a point on the circle is 10. Since you have the radius, all you will have to do is C= 2 pi times (10). So 2 times 10 is 20 so it'll be 20 pi for the circumference.

I hope this helped sorry if it's confusing. If you have any questions please ask.

Two numbers are consecutive positive multiples of 3. Three

Sunny_sXe [5.5K]

Answer:

18, 21

Step-by-step explanation:

Let x represent the smaller number. Then x+3 is the larger number, and the other relation between them is ...

3(x+3) = (7/10)(5x)

6x +18 = 7x . . . . . multiply by 2 and simplify

18 = x . . . . . . . . . . subtract 6x

The two numbers are 18 and 21.
