Level BPick any 2‐digit number where not all the digits are equal. Order the digits
from highest to lowest to create the largest number. Next order the digits
from lowest to highest to create the smallest number. Find the positive
difference between the two numbers. Investigate different solutions you find.
Are there patterns? If so, what patterns did you find?

Answers

Answer 1

Answer: The number has 2 digits - let's call them x and y. The positive difference between the two combinations (lowest-highest and highest-lowest) is always equal to the positive difference of x and y, multiplied by 9.

For example:

76 and 67: 76 - 67 = 9 and ((7-6)*9) = 1*9 = 9
73 and 37: 73 - 37 = 36 and ((7-3)*9) = 4*9 = 36

An angle measures 125 through what fraction of a circle does the angle turn

Answers

Answer: Fraction of a circle the angle turn is $(25)/(72)$

Step-by-step explanation:

Since we have given that

Measure of an angle = 125°

As we know that

Total angle formed by a circle = 360°

So, Fraction of a circle when the an angle 125° turn is given by

$(125)/(360)\n\n=(25)/(72)$

Hence, Fraction of a circle the angle turn is $(25)/(72)$

whole circle=360
125/360=25/72=

fraction is 25/72 of the circle

Answer:

D. $A\subset \mathbb{R}*\mathbb{R}.$

Step-by-step explanation:

Consider the set

$A=\left\{(2,3),\ (5,1),\ (-3,-2),\ (0,3)\right\}$

This set consists of four ordered pairs.

The first numbers in these pairs are $2,\ 5,\ -3,\ 0.$ These numbers are integer numbers (not natural, because -3 is negative).

The second numbers in these pairs are $3,\ 1,\ -2,\ 3.$ These numbers are integer numbers too (not natural, because -2 is negative).

Options contain only natural and real sets, so, the first and the second numbers are real numbers and

$A\subset \mathbb{R}*\mathbb{R}.$

Answer:

D. R X R

Step-by-step explanation:

The answer is choice D because, the set of the actual numbers of R has a 0 so A is a subset of R X R

What is 25/30 + 10/30 (25/30 + 10/30 is fraction)I need the answer bc tomorrow is school and where gonna give the homework to or teacher

Answers

Step-by-step explanation: To simplify the expression 25/30 + 10/30, we first need to find a common denominator. The least common multiple of 30 and 30 is 30 itself, so we can multiply all the fractions by 30. This gives us:

(25/30)(30/30) + (10/30)(30/30) = 75/90 + 10/90

Next, we add the fractions:

75/90 + 10/90 = 85/90

Therefore, 25/30 + 10/30 = 85/90.
