Considering an arbitrary number system with the independent digits as 0,1 and x. What is the radix of the number system
Using it's concept, it is found that the radix of the arbitrary number system is of 3.
What is the radix of a number system?It is the number of different digits that the system has, for example:
The binary system has radix 2, as it has digits 0 and 1.The decimal digit has radix 10, as it has 10 digits from 0 to 9.In this problem, the digits are 0, 1 and x, hence the radix of the arbitrary number system is of 3.

what happens to the volume of a sphere when it is quadrupled?
The volume of the sphere, which is quadrupled, is 64 times the initial volume or in other words, the volume of the quadrupled sphere increases by 64 times.
What is volume?The capacity occupied by a three-dimensional solid shape is known as volume. It is difficult to visualize in any shape, yet it may be compared among shapes. For instance, a compass box has a larger volume than an eraser placed inside of it.
Given:
There is a sphere that converts into the quadrupled sphere,
The volume of the sphere can be given as shown below,
Initial Volume = 4 / 3 π a³
Here a is the radius of the sphere
When the sphere is quadrupled, the new radius will be 4a,
The volume of new sphere = 4 / 3 π (4a)³
The volume of new sphere = 4 / 3 π × 64 a³
The volume of the new sphere = 64 × 4 / 3 π a³
The volume of the new sphere = 64 × Initial Volume

Answer:
[tex]\huge\boxed{\sf FG = 20.3 }[/tex]
Step-by-step explanation:
If two secants are drawn from a point outside the circle, then the formula used for it will be:
(FG + GH) × GH = (JI + IH) × IH
Given that IH = 29, JI = 23 and GH = 30
(FG + 30) × 30 = (23 + 29) × 29
(FG + 30) × 30 = 52 × 29
(FG + 30) × 30 = 1508
Divide both sides by 30
FG + 30 = 1508 / 30
FG + 30 = 50.3
Subtract 30 to both sides
FG = 50.3 - 30
FG = 20.3

Can anyone explain to me what the pythagorean theorem is? I never received an explanation when I asked my teacher for help
Answer:
In mathematics, the Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle.
Step-by-step explanation:
It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. This theorem can be written as an equation relating the lengths of the sides a, b and c, often called the Pythagorean equation: a²+b²=c², where c represents the length of the hypotenuse and a and b the lengths of the triangle's other two sides.

so let's take a peek at the table, so hmmm when x = -1, b(x) = 1, so we have the point (-1 , 1), and when x = 2, b(x) = 7, so we have the second point of (2 , 7)

Joelle earns her regular pay of $12.50 per hour for up to 40 hours of work in a week. For each hour over 40 hours in a week, Joelle is paid 1 1/2 times her regular pay. How much does Joelle earn for a week in which she works 48 hours?
answer:
well, 600
Step-by-step explanation:
1. joelle got 12.50/h
2. she work to 40h/w
3. 12.5x40= e/w, is equal to 20+(12x40) = 500.
4. 500 + 1h/$12.5, 8h = 500 + 8x12 + 8x(1/2)
5. 500 + 96 + 8x1/2(8 x 1/2 is 4 because it is the hath) = 600

Dana wants to build a rectangular pen for her goats. The length of the pen should be at least 50 feet, and the perimeter of the pen should be
no more than 190 feet.
The width of the pen must not be less than 45 feet
Perimeter of the penThe formula for calculating the perimeter of a rectangle is expressed as:
P = 2(l + w)
Given the following
P = 190feet
l = 50feet
Required width
190 = 2(50 + w)
95 = 50 + w
w = 45
Hence the width of the pen must not be less than 45 feet

Step-by-step explanation:
(4x-5y)-(x-y) if x=6 and y=-4
step one:
4x=24
5y=-20
24- (-20)= 44
x-y=10
44-10=34
I'm pretty sure I'm right because I worked it out on a calculator and if it changed the minus in 4x-5y to a + then that means the minus here
