The number of possible ways to create the flag with 6 colors in total and 3 colors to be used in the flag is 30 ways.
We are given that:
Total colors in a palette = 6 colors.
Colors to be used in making of the flag = 3 colors.
So, by using the permutations, we get that:
Number of possible ways to create the flag = 6 × 5 ways.
Number of possible ways to create the flag = 30 ways.
Therefore, we get that, the number of possible ways to create the flag with 6 colors in total and 3 colors to be used in the flag is 30 ways.

Expand each binomial.
(2 x-y)⁴
Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. (2x - y)⁴ is expanded as 16x⁴ − 32x²y + 24x²y² − 8xy³ + y⁴.
What is meant by binomial expansion theorem?The Binomial theorem tells us how to expand expressions of the form (a + b)ⁿ, for example, (x + y)⁷. The larger the power is, the harder it is to expand expressions like this directly.
The total number of terms in the expansion of (x+y)ⁿ are (n+1).
The sum of exponents of x and y is always n.
nC₀, nC₁, nC₂, … .., nCₙ are called binomial coefficients and also represented by C₀, C₁, C₂, ….., Cₙ
The binomial coefficients which are equidistant from the beginning and from the ending are equal.
i.e. nC₀ = nCₙ, nC₁ = nCₙ₋₁ , nC₂ = nCₙ₋₂ ,….. etc.
Let the function be (2x - y)⁴
By using binomial expansion theorem, we get
(2x - y)⁴ = 16x⁴ − 32x²y + 24x²y² − 8xy³ + y⁴
(2x - y)⁴ is expanded as 16x⁴ − 32x²y + 24x²y² − 8xy³ + y⁴

For Comic Relief Stamford Green School are taking part in a "Bake Off".
Parents are invited to come and buy cakes. 150 parents attend: 70% donate £1 for their cake and the rest donate £2 for their cake. How much money is donated in total?
Start off with %70 of 150
0.7 • 150 = 105
To find their total donation amount,
105 • £1 = £105
Then we know the rest of the parents account for the last %30 of the attendees
We can find this out by either,
150 - 105
or
0.3 • 150
Either way we end up with 45
45 • £2 = £90
%70 (105) of the parents donated £105
%30 (45) of the parents donated £90
The parents, in total, donated £195

Answer:
Below in bold.
Step-by-step explanation:
7x - 2 + 9x - 2 + 2(5x) = 2(5x + 5) + 2(4x)
7x + 9x + 10x - 4 = 10x + 10 + 8x
7x + 9x + 10x - 10x - 8x = 10 + 4
8x = 14
x = 14/8 = 7/4

Step-by-step explanation:
The perimeter of a trapezium is calculated with the following formula:
P = a + b + c + d (a, b: bases, c, d: sides)
The perimeter of a rectangle is calculated with the following formula:
P= 2(a + b) (a: base, b: side)
we will write the following equation to find the length of ST
7x - 2 + 9x - 2 + 5x + 5x = 2(5x + 5 + 4x) first do the inside the parenthesis
2(9x + 5) = 18x + 10
Now,
7x - 2 + 9x - 2 + 5x + 5x = 18x + 10 add like terms on the left side of the equation
26x - 4 = 18x + 10 transfer like terms to the same side of the equation
26x - 18x = 10 + 4 add/subtract
8x = 14 divide both sides by 8
x = 1.75 replace x with this to calculate the lentgh of ST
5x + 5 = 5*(1.75) + 5 and ST = 13.75

What is the blue dot on
Sheridan Street and Richmond Street are parallel, and both are intersected by University Boulevard.
Two cars are heading west, one on Sheridan St. and one on Richmond St. Both cars turn north onto University Blvd.
What is the measure of the angle of their turn on to University Blvd.
The measure of the angle of their turn on to University Blvd is; 80°
How to interpret corresponding angles?
Corresponding angles are the angles that are formed when two parallel lines are intersected by the transversal.
Thus, from the given diagram when we apply the concept of corresponding angles, we can say that;
17x + 15 = 19x + 5
19x - 17x = 15 - 5
2x = 10
x = 5
Thus;
19x + 5 = 19(5) + 5 = 100°
Now, the sum of the angles on a straight line is 180 degrees. Thus, the measure of the angle of their turn on to University Blvd is;
180 - 100 = 80°

The radius of a circle can be expressed as r=√A/π inches where r is the radius and A is the area of the circle. If the area of a circle is 169 π in.², what is its radius?
The radius is 169 inches.
As per the known fact, the radius and area of circle are related by the formula -
Area = πr²
So, rewriting the expression in equation -
r=√(A/π)²
As mentioned, r is the radius and A is the area of the circle and π is constant
Keep the value of A in the above mentioned rewritten equation to find the value of radius of circle.
r = √(169π/π)²
On solving the above equation we get the new equation, which is as follows -
r = 169π/π
Cancelling π as it is common in both numerator and denominator
r = 169 inches
Hence, the radius of circle is 169 inches.

What is a natural logarithm?A number's natural logarithm is its logarithm to the base of the transcendental and irrational number e, which is roughly equivalent to 2.718281828459.
Typically, the natural logarithm of x is denoted by the symbols ln x, loge x, or, if the base e is implicit, just log x. When adding parentheses for clarity, the values ln(x), loge(x), or log (x). In order to avoid ambiguity, this is notably done when the argument to the logarithm is not a single symbol.
The power to which e would need to be raised in order to equal x is the natural logarithm of x.
For instance, e2.0149... = 7.5, thus ln 7.5 equals 2.0149.
Since e1 = e, the natural logarithm of e itself, or ln e, is equal to 1, while the natural logarithm of 1 is 0, since e0 = 1.
