The composition of the mixture is: 7.323 pounds of the variety priced at $5.77 per pound and 2.677 pounds of the variety priced at $8.87 per pound.

To solve this problem, we can use a system of equations. Let x be the number of pounds of the first variety of birdseed, and y be the number of pounds of the second variety of birdseed.

The first equation will represent the total weight of the mixture:
x + y = 10

The second equation will represent the total cost of the mixture:
5.77x + 8.87y = 6.70(10)

Now we can use the elimination method to solve for one of the variables. Multiply the first equation by -5.77 to eliminate the x variable:
-5.77x - 5.77y = -57.7

Add this equation to the second equation:
3.1y = 8.3

Solve for y:
y = 2.677

Now we can plug this value back into the first equation to solve for x:
x + 2.677 = 10
x = 7.323

So, there are 7.323 pounds of the first variety of birdseed and 2.677 pounds of the second variety of birdseed in the mixture.

The lengths of a and b are 9.4 and 12 respectively using the Pythagorean theorem.

Pythagoras theorem states for a right angled triangle that, the sum of the squares of base and altitude is the square of the hypotenuse.

Given are two right angled triangles.

For the first right angled triangle, we have to find the length of the hypotenuse.

Using Pythagoras theorem,

a² = 8² + 5²

a² = 64 + 25

a² = 89

a = √89 = 9.43398 ≈ 9.4

For the second right angled triangle, we have to find the length of the altitude.

Using Pythagoras theorem,

Based on the figure, the measure of the angle GPY is 118 degrees.

Alternate angles are a pair of angles that are formed by a transversal intersecting two parallel lines.

When a transversal intersects a parallel line, it creates four angles.

Alternate angles are the pairs of angles that are on opposite sides of the transversal and on opposite sides of the parallel lines.

The key property of alternate angles is that they are congruent, meaning they have the same measure.

Here angle GPY is alternate to angle RPK.

Thus;

8p + 94 = 5p + 103

8p - 5p = 103 - 94

3p = 9

The three possible forms of any positive odd integer, as required.

According to the Euclid Division Lemma, for any two positive integers a and b, there exist unique integers q and r such that a = bq + r where 0 ≤ r < b.

We can use this lemma to show that any positive odd integer is of the form 6q + 1, 6q + 3, or 6q + 5 where q is some integer.

Let a be any positive odd integer and let b = 6. By the Euclid Division Lemma, we can write a = 6q + r where 0 ≤ r < 6. Since a is odd, r cannot be an even number. Therefore, r can only take on the values of 1, 3, or 5.

Thus, we can write a as:

a = 6q + 1
a = 6q + 3
a = 6q + 5

The torque required to maintain motion of the rotating conical body in the oil film is 0.149 N·m.

The torque required to maintain motion of a rotating conical body in an oil film can be found using the equation T = (2πμωR^3h)/ln(R/h), where T is the torque, μ is the viscosity of the oil, ω is the angular velocity of the cone, R is the radius of the base of the cone, and h is the thickness of the oil film.

First, we need to convert the given values into the appropriate units. The diameter of the base of the cone is 18cm, so the radius is 9cm or 0.09m. The thickness of the oil film is 0.8mm, or 0.0008m. The viscosity of the oil is 4·10^-3 N·S/m^2, and the angular velocity of the cone is 37 rad/s.

Now we can plug these values into the equation:

T = (2π)(4·10^-3 N·S/m^2)(37 rad/s)(0.09m)^3/(0.0008m)

T = 0.149 N·m

Therefore, the torque required to maintain motion of the rotating conical body in the oil film is 0.149 N·m.

To select the indicated motor, we need to find a motor that can provide a torque of at least 0.149 N·m. This will ensure that the motor can maintain the constant motion of the conical body in the oil film.

Simplify both sides of the equation using algebraic methods and see if they are equal or not equal.

What is Linear Equation?

A linear equation is a mathematical equation that represents a straight line on a graph. It is an equation in which the highest power of the variable is one. A general linear equation can be represented as y = mx + b, where y is the dependent variable, x is the independent variable, m is the slope of the line, and b is the y-intercept.

Linear equations can be solved algebraically using techniques like substitution or elimination, and they can be used to model real-world situations involving linear relationships.

If an equation is true for all values of x, then it is called an identity. To check if an equation is an identity, we can simplify both sides of the equation using algebraic methods and see if they are equal. If they are, then the equation is an identity.

On the other hand, if an equation is true for no values of x, then it is a contradiction. In this case, we can also simplify both sides of the equation using algebraic methods and see if they are not equal. If they are not, then the equation is a contradiction.

If neither of these cases applies, then the equation may be true for some values of x but not for others.

If 41 grams of sugar is 14% of the normal daily allowance for sugar, we can set up a proportion to solve for the recommended amount:

41 grams / x = 14% / 100%

where x is the recommended amount of sugar.

To solve for x, we can cross-multiply and simplify:

41 / 0.14 = x / 1

x = 292.86

Rounding to the nearest gram, the recommended amount of sugar in a normal diet is approximately 293 grams.

The simplified expression is a^(-(3)/(8)).

To simplify the expression (a^(-(1)/(2)))/(a^(-(1)/(8))), we need to use the properties of exponents. Specifically, we will use the property that states that when dividing two expressions with the same base, we can subtract the exponents.

So, in this case, we have:

(a^(-(1)/(2)))/(a^(-(1)/(8))) = a^(-(1)/(2) - (-(1)/(8)))

Step-by-step explanation:

given Δ ABD is isosceles with AB = AD

then the base angles are congruent , that is

∠ ABD = ∠ ADB = 25°

given ABC is a straight line then the 3 angles on it sum to 180° , that is

∠ ABD + x + 115° = 180°

The polynomial can be written as:

f(x) = x³ - 3x² + 4x - 2

We know that the degree is 3, and two of the roots are x = 1 and x = 1 + i.

Then the last root must be 1 - i, so the polynomial is real, then if the leading coeficient of the polynomial is a, we can write:

f(x) = a*(x - 1)*(x - (1+ i))*(x - (1 - i))

Expanding that:

f(x) = a*(x - 1)*[x² -2x + 2]

f(x) = a*(x³ - 2x² + 2x - x² + 2x - 2)

f(x) = a*(x³ - 3x² + 4x - 2)

And we know that f(0) = -2, then we need to solve:

-2 = a*(0³ - 3*0² + 4*0 - 2)

-2 = a*-2

There are a total of 32 possible sequences because there are two alternatives for each stage. Since there are more than seven distinct ways to mount the stairs, the priestess can do so every day for a week.

(a) Every day, the priestess at the temple of Horus must climb a flight of five stairs, which she can do by taking one or two steps at a time. The amount of ways she can up the stairs on any given day can be represented by a binary digit, where 1 denotes a two-step ascent and 0 denotes a one-step ascent. For each of the five steps, for instance, 00101 reflects the order of her one- and two-step climbs.

(b) The same regulations apply. The entire number of potential sequences, using the same binary digit format, is 213 = 8,192. There are therefore more than 365 possible ways to mount the grand staircase, allowing the priest to do so every day for a whole year.

In conclusion, the number of alternative binary sequences, where each digit denotes a one- or two-step climb, may be used to determine the number of ways the priestess can ascend the five-step flight of stairs and the number of ways the priest can ascend the thirteen-step grand staircase.
