Simplifying indices expressionsGiven the indices expression (x^1/2/(x^1/3)^1/5
Using the indices law below:
a^m/a^n = a^m-n
(a^m)^n
Applying the law above to the given equation
(x^1/2/(x^1/3)^1/5 = (x^1/2-1/3)^1/5
(x^1/2/(x^1/3)^1/5 = (x^1/6)^1/5

I cant find my answer please help!
Step-by-step explanation:
once we know what the domain and the range of a function is, this is very simple.
the domain is the interval or set of all valid x (input) values.
the game is the interval or set of all valid y (function result) values.
so, what are all the valid x values ? that means for how many months of collection can we use this function to see how many figurines he has ?
well, we can stay with 0 (what he currently has) and go up to 5 (because after 5 months he does not want to continue this behavior).
so, the domain is
0 <= x <= 5 if we allow also fractions of months as input (if this makes sense)
or
x € {0, 1, 2, 3, 4, 5} if we allow only whole numbers.
and the range ? what are the possible result values of the function ?
for x = 0 it starts with y (or f(x)) = 100.
x = 1 gives us 100 + 3×1 = 103
x = 2 gives us 100 + 3×2 = 106
x = 3, 100 + 3×3 = 109
x = 4, 100 + 3×4 = 112
x = 5, 100 + 3×5 = 115
so, the range is
100 <= y <= 115 if we allow fractions of months
or
y = f(x) € {100, 103, 106, 109, 112, 115} if we allow only whole months as values of x.
the sum of three numbers is 111. the first number is less than the third. the second number is times the third. what are the numbers?
The first, second, and third numbers are 11, 80, and 20 respectively.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say the first number is a second is b and the third one is c
Now,
The sum of the three numbers is 111
So,
a + b + c = 111
The first number is 9 less than the third
So.
a = c - 9
And the second number is 4 times third
So,
b = 4c
By substitution,
c - 9 + 4c + c = 111
c = 20
b = 4(20) = 80
a = 20 - 9 = 11
Hence "The first, second, and third numbers are 11, 80, and 20 respectively".

Lisa and john are bowling. Johns score is three times the difference of Lisa's score and 6. The sum of their scores is 382. Find each students bowling score
Lisa bowling score is 100.
John bowling score is 282.
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
Lisa and John are bowling.
Johns score is three times the difference of Lisa's score and 6.
The sum of their scores is 382.
Now, Let Lisa bowling score = x
Then, John bowling score = 3 (x - 6)
Since, The sum of their scores is 382.
Hence,
x + 3 ( x - 6 ) = 382
After solving,
x + 3x - 18 = 382
4x = 382 + 18
4x = 400
x = 100
Hence, Lisa bowling score = x = 100
And, John bowling score = 3 (x - 6)
= 3 (100 - 6)
= 3 × 94
= 282
Therefore, Lisa bowling score is 100.
And, John bowling score is 282.

share £60 in the ratio 3:1
If we share $60 in the ratio 3:1, then each person will get is $45 and $15 respectively
Given,
The total amount = $60
The ratio = 3:1
Then the amount given to first person = 3x
The amount given to the second person = x
Given that the total amount is 60
Then the equation will become
x+3x=60
4x=60
x=[tex]\frac{60}{4}[/tex]
x=15
The amount given to the first person = 3x
Substitute the value of x in the equation
The amount given to the first person =3x

The amount given to the second person =x
= $15

How to illustrate the area?It should be noted that the radius of the outer circle will be:
= Diameter / 2
= (8 + 8 + 4 + 4)/2
= 24 / 2
= 12cm
The area of the circle = πr²

= 452.16 cm²
The area of the circle with radius 8cm = 200.96 cm²
The area of the circle with radius 4cm =50.24cm².
The area of the shaded region:

Find the slope of the line passing through the given points. how do you know?
The slope of the line passing through the given points is 0.4 or 2/5.
From the table given below, we have (2, 23) and (5, 24.3).
What is the slope of the line passing through the coordinate points?Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y-values over the change in the x-values.
Put the points (2, 23) and (5, 24.3) in the slope formula and find the slope.
That is, m=(24.3-23)/(5-2)
=1.3/3
=0.4
=4/10 = 2/5
Put m=2/5 and the coordinate points (2, 23) in y=mx+c.
That is, 23=2/5 (2)+c
⇒23 - 4/5 =c
⇒111/5 = c
⇒ c=22.2
Now, equation is y=0.4m+22.2

Continuing with the expression (x+7), do the following.
(a) By using the Distributive Property twice, show
that this expression is equivalent to
x² +14x+49.
35
(b) Test the equivalency by finding the value of
(x+7)² and x² +14x+49 when x = 3.
x² +14x+49
(x+7)²
(a) Using the distributive property ( x + 7 )² is equal to x² + 14x + 49.
(b) When x = 3, the expressions ( x + 7 )² and x² + 14x + 49 are equal.
Consider the expression ( x + 7 ),
Now when we square the expression we get,
( x + 7 )² = ( x + 7 ) ( x + 7 )
Using the distributive property,
( x + 7 )² = x( x + 7 ) + 7( x + 7 )
Again by using distributive property,
( x + 7 )² = x² + 7x + 7x + 49
( x + 7 )² = x² + 14x + 49
(b) For the expressions ( x + 7 )² and x² + 14x + 49,
When x = 3,
( x + 7 )² = ( 3 + 7 )²
( x + 7 )² = 10²
(x + 7 )² = 100
When x = 3,
x² + 14x + 49 = 3² + 14 × 3 + 49
x² + 14x + 49 = 9 + 42 + 49
x² + 14x + 49 = 100
Hence, the expressions (x+7)² and x² + 14x + 49 are equal when x = 3.

In a survey the ratio of students who prefer muffins to bagels is 4 to 5 if the number of students surveyed who prefer muffins is 420 how many prefer bagels
In a survey where the ratio of students who prefer muffins to bagels is 4 to 5 and 420 prefer muffins, 525 students prefer bagels.
Ratio is the relationship between two quantities, normally expressed as the quotient of one divided by the other.
It can be expressed in different ways:
1) Use the ":" to separate the values : a : b
2) Use the word "to" : a to b
3) Write it in fraction: a / b
On the other hand, proportion is the equality of two ratios, such that
a : b = c : d
Given a proportion, the product of its means must be equal to the product of its extremes. That is:
ad = bc
If the ratio of students who prefer muffins to bagels is 4 to 5, and 420 students prefer muffins, the proportion can be written as:
4 : 5 = 420 : n
where n = number of students who prefer bagels
Solving for n,
4n = 5(420)
4n = 2100
n = 525
