On a merry-go-round, you stand 15 feet from the center while your friend stands 10 feet from the center. How would you find how much further you travel in one revolution than your friend? What is that distance?
Answer:
Revolution traveled by me = 30π ft.
Revolution traveled by my friend = 20π ft.
Difference between revolutions = 10π ft.
Step-by-step explanation:
In one revolution, I travel 2π(15) = 30π ft., and my friend travels 2π(10) = 20π ft., so my revolution is 30π - 20π, or 10π, ft. longer than my friend's revolution.

Knowing that segment BD is of length 26, and C is the midpoint then BC is half of BD. The value of x is solved to be 11/3
How to find x in the equation BC = 6x - 9Given data
length of segment BD = 26
C midpoint of BD
BC = 6x - 9
If C midpoint of BD, then BC is half of BD. This is shown mathematically as
BC = 1/2 * BD
BC = 1/2 * 26
BC = 13
substituting BC = 13 into BC = 6x - 9, we have
BC = 6x - 9
13 = 6x - 9
13 + 9 = 6x
6x = 22
x = 22/6
x = 11/3 in fraction
x = 3.6667 in decimal notation.
Hence we can say that the value of x in the equation is 11/3

The total amount of coal delivered in these two months is equal to 6.35 tons.
What is a conversion factor?A conversion factor can be defined as a number that is typically used to convert (change) a number in one (1) set of units to another, either by dividing or multiplying.
Generally speaking, an appropriate conversion factor to an equal value must be used when it is necessary to perform any mathematical conversion.
Conversion:
1 lbs = 0.0005 tons
1500 lbs = 0.75 tons
1200 lbs = 0.6 tons.
Now, we can determine the total amount of coal delivered in these two months:
Total amount of coal = 3 tons + 0.75 tons + 2 tons + 0.6 tons

A rectangle has a length of 6 feet and a width of 4 feet. The perimeter of the rectangle
can be found using the equation P=2x6+2x4. Which equation can also be
used to find the perimeter of the rectangle?
Answer: The equation can also be used to find the perimeter of the rectangle P = 4 × ( l + w).
Step-by-step explanation:
Given data,
A rectangle has a length of 6 feet and a width of 4 feet.
The perimeter of the rectangle can be found using the equation =2×6+2×4.
P = 2×6+2×4
Let l be the length and w be the width of a rectangle.
Since there four sides of a rectangle, the perimeter is given by adding all the sides.
Therefore perimeter of the rectangle is given by
= l + l + b + b
= 2×l +2×w
= 2 × ( l + w).
The equation given by 2 × ( l + w) can also be used to find the perimeter of any given rectangle.
We can use,
P = 4x4x6
Therefore perimeter of the rectangle is given by
= l + l + b + b
= 4×l +4×w
= 4 × ( l + w).
substitute l and w values,
Then,
= 4 × ( l + w)
P = 4 × ( 6 + 4).
The equation given by 4 × ( l + w) can also be used to find the perimeter of any given rectangle.
Therefore,
The equation can also be used to find the perimeter of the rectangle P = 4 × ( l + w).

simplify |8-40/4^3| 4^2 - 8 A.0 B.10 C.20 D.30
The required answer for the given expression is 0.
What is simplification?Simplification generally means finding an answer for the complex calculation that may involve numbers on division, multiplication, square roots, cube roots, plus and minus.
Now the given expression is,
|8-40/4^3| 4^2 - 8
Solving the mod first,
Since 4^3 = 64 ; 4^2 = 16,
and 8 - 40 = -32
Therefore,
|8-40/4^3| 4^2 - 8 = |-32/64|16 - 8
Now solving
⇒ 32/64 = 1/2
Therefore we get,
|8-40/4^3| 4^2 - 8 = |-31/2| 16 - 8
Now since, |-a| = a
therefore, |-1/2| = 1/2
Therefore we get,
|8-40/4^3| 4^2 - 8 = (1/2) 16 - 8
Now, since (1/2) 16 = 8
Therefore we get
|8-40/4^3| 4^2 - 8 = 8 - 8
solving we get,
|8-40/4^3| 4^2 - 8 = 0
this is the required answer for the given expression.

Find the inverse of each function. Is the inverse a function?
f(x)=(x+1)²
In mathematics, an inverse function is one that "reverses" another function. The inverse of the function f(x) = (x+1)² is √x−1.
What is meant by inverse function?The inverse function of a function f in mathematics exists a function that reverses the operation of f. If the inverse of f exists, it is shown by the f⁻¹. The inverse of f exists if and only if f is bijective.
An inverse in mathematics is a function that "undoes" another function. In other words, if f(x) produces y, then y entered into the inverse of f produces x. An invertible function is one that has an inverse, and the inverse is represented by the symbol f ⁻¹.
If we restrict the domain to [−1,∞), then this new function has an inverse:
g(x) = (x+1)² with x ≥ −1
y = (x+1)²
if and only if
x+1 = √y (We do not need ±√y because of the restriction on x.)
x = √y−1
g−1(x) = −√x−1
If we restrict the domain to (−∞, −1], we get
h(x) = (x+1)² with x≤−1
y = (x+1)²
if and only if
x+1 = −√y (We need only −√y because of the restriction on x.)
x = −√y−1
h − 1(x) = √x−1
The inverse of the function f(x) = (x+1)² is √x−1.

A bicyclist brakes from 21 m/s to stop in 32.3 m. what is the acceleration of the bicyclist
The acceleration of the bicyclist is 6.83 m/s².
The given parameters;
Initial velocity of the bicycle (u) = 21 m/s
Distance travel by the bicycle (s) = 32.3 m
We have to find the acceleration of the bicyclist.
How to calculate the acceleration?
If the initial velocity is u, final velocity is v and distance travel by object is s then we can calculate acceleration as;
v² = u² + 2as
Initial velocity of the bicycle (u) = 21 m/s
Distance travel by the bicycle (s) = 32.3 m
Final velocity of the bicycle (v) = 0
Hence, The acceleration of the bicycle is calculated as follows;
v² = u² + 2as
Where, v is the final velocity of the bicycle.
0 = u² + 2as
2as = - u²
a = - u²/2s
a = - (21)²/2*32.3
a = - (21)²/64.6
a = -441/64.6
a = -6.83
| a | = 6.83 m/s²

Add or subtract if possible. 3√20x + 8√45x -4√5x
The subtraction of the expression 10√27 - 4√12 is 22√3.
Combining things and counting them as one big group is done through addition. In math, addition is the process of adding two or more integers together.
In mathematics, subtraction involves removing anything from a group or a number of objects. What is left in the group gets smaller when you subtract.
Consider the expression,
y = 3√20x + 8√45x - 4√5x
Now, the number in the root can also be written as:
20 = 2 × 2 × 5
45 = 5 × 3 × 3
Therefore,
y = 3√20x + 8√45x - 4√5x
y = 3( √[2 × 2 × 5] )x + 8( √[5 × 3 × 3] )x - 4√5x
y = 3 × 2√5x + 8 × 3√5x - 4√5x
y = √5x ( 3 × 2 + 8 × 3 - 4 )
