If there are 2 office rooms, there are 6 rooms that aren't office rooms. So the percentage of non-office rooms can be expressed as:

# of non-office rooms/total rooms

or

6/8

In percentage, this is 75%

Hope this helps!

Which equation is the Gizmo using to find the x coordinates​
wlad13 [49]

Answer:

The correct answer is C. (0,10).

Step-by-step explanation:

The polar coordinates are defined in terms of r and θ, where r is the distance of the point from the origin and θ is the angle made with the positive x-axis.

To convert from Polar Coordinates (r, θ) to Cartesian Coordinates (x, y) apply the following conversion formulas:

                                                      x = r\cos \theta \\y = r\sin \theta

We know that r=10 and \theta = 0.5\pi

So, the cartesian coordinates are,

x=10\cos \left(0.5\pi \right)=10\cos \left(\frac{1}{2}\pi \right)=10\cos \left(\frac{\pi }{2}\right)\\\\\mathrm{Use\:the\:following\:trivial\:identity}:\quad \cos \left(\frac{\pi }{2}\right)=0\\\\x=10\cdot \:0\\x=10

y=10\sin \left(0.5\pi \right)=10\sin \left(\frac{1}{2}\pi \right)=10\sin \left(\frac{\pi }{2}\right)\\\\\mathrm{Use\:the\:following\:trivial\:identity}:\quad \sin \left(\frac{\pi }{2}\right)=1\\\\y= 10

The correct answer is C. (0,10).

In number theory, two integers a and b are said to be relatively prime, mutually prime, or coprime if the only positive integer
Elina [12.6K]

ANSWER

The number that fills in the blanks is 1

<u>EXPLANATION</u>

Two numbers are relatively prime if they have no common factor greater than 1.

For exam 12 and 17 have no common factor greater than 1.

This is equivalent to saying that the greatest common divisor (GCD) of the two numbers is 1.


gcd(12,17)=1

This means that 12 and 17 are relatively prime.


But

gcd(12,16)=4. This means 12 and 16 are not relatively prime or coprime
