Answer:6
Step-by-step explanation:
18-12=6
The difference in circumference between the goal and the center cross-section of a basketball is 26.4inches.
It is given that
Diameter of a basketball goal = 18inches
So, the radius will be 18/2 = 9inches
It is the length of the outer periphery of a circle equals 2*π*r, where r is the radius of the circle.
Circumference of goal = 2*π*9 = 56.57inches
Diameter of basketball = 9.6inches
So, the radius of basketball will be 9.6/2 = 4.8 inches
Circumference of cross-section of basketball = 2*π*4.8 = 30.17inches
So, the difference in circumference between the goal and the center cross-section of a basketball = 56.57-30.17 = 26.4inches.
Therefore, difference in circumference between the goal and the center cross-section of a basketball is 26.4inches.

C: Lupe says that if any number is divisible by n, you can easily separate it into n equals parts. Do you agree with her? Explain.
Answer:
Step-by-step explanation:
A. Yes,Miguel is correct because all even numbers are the multiple of 2 and when we divide any even number resultant will be a whole number which represents the number of equal parts.
Example: 8 ÷ 2 = 4
B. Yes, Because all numbers which are multiple of 3, when divided by 3 resultant will be a whole number which represents the equal number of parts.
Example : 6 ÷ 3 = 2
C. Yes, Lupe is correct. When any number multiple of n is divided by n we get a whole number which represents the number of parts divided equally.
Example : 2n ÷ n = 2
There is an error in the student's work, the remainder should be 10
The division operation is one of the basic arithmetic operations
Common signs used are or
The division is written by placing the numerator above the denominator with a horizontal line between them or use a slash with the numerator's position and the denominator is parallel
The division is actually an iterative subtraction operation (as many as the number of divisors)
Division is the opposite of multiplying
The general form of division can be stated by:
example:
7: 3 = 2 + 1
Division operation statement:
"7 divided by 3 equals 2 remainder 1"
The form of division can also be expressed in terms of fractions
In the example above, the form of mixed fractions :
Mixed fractions consist of whole number and proper fractions
From the task

When dividing 878 by 31, a student finds a quotient of 28 with a remainder of 11.
Division operation statement:
"878 divided by 31 equals 28 remainder 11
Arithmetic operations :
878 : 31 = 28 + 11
Because Division is the opposite of multiplying, so we check the solution with multiplying
divident - (divisor x quotient) = remainder
878 - (31 x 28) = 11
878 - 868 = 11
10 ≠ 11
So students make mistakes in subtraction operations,remainder should be 10
