Answer: The second option (purple model)
Step-by-step explanation: It is that option because there were 80 toys collected which is 100% and then we do not what the 30% is.
Answer:
7z is the sum of seven 'z's while z to the power of z is the multiplication of z to itself z times.
Step-by-step explanation:
7z is 7 times of z.
7z= z +z +z +z +z +z +z
z⁷ (z to the power of 7) is multiplying z by itself 7 times.
z⁷= z ×z ×z ×z ×z ×z ×z
Equation:
100 = 80 + 4x
*You can use any variable I just chose x*
This is the equation for a circle which without numbers looks like (x – h)^2 + (y – k)^2 = r^2
This means that the radius is the square root of what ever number the equation is equal to. Since in this case it is 4 the square root of 4 is 2
The center of the circle is baced off h and k. In order to find where each one of them go, you would do the opposit of the number that is with them. With this equation the opposit of 4 is -4 so it will go -4 in the x direction and the opposit of -7 is 7 so it would go 7 in the y direction
Radius: 2
Center: (-4,7)
