The number z and 0.8 are additive inverses. Drag and drop 0.8 and z to their correct positions on the number line. Drag and drop
UkoKoshka [18]

we know that

If two numbers have a sum of zero, then we say they are additive inverses.

so

z+0.8=0 -------> the sum is equal to zero

z=-0.8------> the additive inverse of z is equal to -0.8

using a graph tool

What is the standard form of the equation of the circle?
lisabon 2012 [21]
The standard form of the equation of a circle is:
(x - a) {}^{2}  + (y - b) {}^{2}  = r {}^{2}
Where the point (a,b) represents the centre and r is the radius. So, given your information, the equation will be:

What is the number of sides of a regular polygon if each interior angle measures 160°?
Temka [501]

Answer:

18

Step-by-step explanation:

180-160 = 20 which equals the exterior angle

the sum of exterior angles is 360 so 360/20 = the number of sides as there is an exterior angle for every side

360/20 = 18
