Answer: 3
Step-by-step explanation: try to solve for a by itself by multiplying it on both sides that give you 3 = 1*a. that simply just means that a is equal to 3, so you substitute three to the a variable that will give 3/3 that's equal to 1.
Use Eurlid division lemma to show that any positive odd integer is of the form /(6 q+1./)/(6y+3/) or ,/)/(6y+5,?) where /(q/) is some integers
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
These are the three possible forms of any positive odd integer, as required.

Which coupon should Clara use to save the most money on a tent originally priced at $46? $24 off or 50% off
Clara should use the 50% off coupon to save the most money on a tent originally priced at $46.
To determine which coupon will save Clara the most money, we need to calculate the final price of the tent with each coupon.
For the $24 off coupon:
Final price = Original price - Coupon amount
Final price = $46 - $24
Final price = $22
For the 50% off coupon:
Final price = Original price - (Original price x Coupon percentage)
Final price = $46 - ($46 x 0.50)
Final price = $46 - $23
Final price = $23
As we can see, the final price of the tent with the $24 off coupon is $22, while the final price with the 50% off coupon is $23. Therefore, Clara should use the $24 off coupon to save the most money.

and the domain of it written using interval notation.
To find the composite functions, we simply substitute one function into the other.
For example, f[g(x)] means we substitute g(x) into f(x) wherever there is an x. So, f[g(x)] = 3(g(x)) + 4 = 3(2x^2 − 5x − 9) + 4 = 6x^2 − 15x − 23.Similarly, we can find the other composite functions: g[f(x)] = 2(f(x))^2 − 5(f(x)) − 9 = 2(3x+4)^2 − 5(3x+4) − 9 = 18x^2 + 7x - 7f[f(x)] = 3(f(x)) + 4 = 3(3x+4) + 4 = 9x + 16
For the last part, f/g means we divide f(x) by g(x):f/g = (3x+4)/(2x^2−5x−9)The domain of this function is all real numbers except for the values of x that make the denominator equal to zero.
To find these values, we set the denominator equal to zero and solve for x:2x^2−5x−9 = 0(2x+3)(x-3) = 0x = -3/2, 3 So the domain of f/g is (-∞, -3/2) ∪ (-3/2, 3) ∪ (3, ∞) in interval notation.

Dave is driving from Portola Ave. To Springs Street. Portola Ave. Is marked as "A" and Springs Street is marked as "E".
He takes 3 miles to go to the ice store. (C)
He drives back to Portola Ave. Where his house is.
From A to C is 6 miles
After a few hours he drives to the market (D)
he spends 25 minutes there and drives back home which is 24 miles.
He stops by a gas station (B) when he goes back home. He takes 10 minutes there.
Then when he’s home, he packs items which takes 55 minutes.
Then he drives to springs street (E)
This takes 40 miles.
He realized that he forgot something at the market, so he drives back to the market which is 5 miles away.
Then he drives back to Springs Street
After he enters the airport (E) he takes 25 minutes to have his luggage checked and boards the plane. Then the plane immediately takes off.
It is 12:45pm when Dave is about to go the ice store.
When he rests for a few hours after coming back from ice store he rests for 2 hours.
What time does the plane take off?
When he rests for a few hours after coming back from ice-store he rests for 2 hours the time the plane takes off is 9:10 pm.
Total distance traveled is 151 miles.
Dave spends 25 + 10 + 55 + 25 = 115 minutes (or 1 hour and 55 minutes) on stops.
Dave rests for 2 hours.
To calculate the time the plane takes off, we need to add up all the time Dave spends on driving, stops, and rests, and then add that time to the time he starts (12:45 pm).
Time to drive from A to C and back to A: 2 * 6 / 60 = 0.2 hours
Time to drive from A to C to D to B to A: (6 + 24 + 24 + 3) / 60 = 0.95 hours
Time to drive from A to C to D to home to E to market to E: (6 + 24 + 24 + 40 + 5 + 5) / 60 = 2.33 hours
Time to rest: 2 hours
Total time spent: 0.2 + 0.95 + 2.33 + 1.92 = 5.4 hours
Time of departure: 12:45 pm + 5.4 hours = 6:25 pm
Adding 45 minutes for the luggage check and boarding, the plane takes off at 6:25 pm + 0.45 hours = 7:10 pm
Adding another 2 hours for the time zone difference, the plane takes off at 7:10 pm + 2 hours = 9:10 pm.

A conical body is rotated with a constant speed of 37 rad/s; the base of the cone has a diameter of 18cm, and the thickness of the oil film is 0.8mm. If the viscosity of the oil is 4·10-3 [N·S/m2 ], find the torque required to maintain motion. Select the indicated motor.
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.

Describe how you know whether an equation will be true for all values of x or true for no values of x.
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.

Is it possible?
How many ways are there of ascending the grand staircase?
Explain why your answer is correct.
please answer this pleaase
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.
How many ways are there of ascending the steps?(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.
How many ways are there of ascending the grand staircase?(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.

Determine the volume of the parallelepiped with one vertex at the origin and the three vertices adjacent to it at \( (3,1,-1),(6,7,1) \), and \( (-6,8,9) \). \[ \text { Volume }=0 \]
The volume of the parallelepiped is 15.
To determine the volume of the parallelepiped with one vertex at the origin and the three vertices adjacent to it at (3,1,-1), (6,7,1), and (-6,8,9), we need to find the scalar triple product of the three vectors formed by these vertices. The scalar triple product is given by the determinant of the matrix formed by the three vectors:
\[ \begin{vmatrix} 3 & 1 & -1 \\ 6 & 7 & 1 \\ -6 & 8 & 9 \end{vmatrix} \]
Expanding the determinant, we get:
\[ \begin{aligned} \text { Volume } &=3\left( \begin{vmatrix} 7 & 1 \\ 8 & 9 \end{vmatrix} \right)-1\left( \begin{vmatrix} 6 & 1 \\ -6 & 9 \end{vmatrix} \right)-1\left( \begin{vmatrix} 6 & 7 \\ -6 & 8 \end{vmatrix} \right) \\ &=3(63-8)-1(54+6)-1(48+42) \\ &=165-60-90 \\ &=15 \end{aligned} \]

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
So a = 1
The polynomial is:
f(x) = x³ - 3x² + 4x - 2

Josh has a furniture store. It cost
Josh $400 to build a cabinet. He
wants to sell the cabinet for
$800. What is his gross profit
margin?
[?]%
Help me…
The gross profit margin of the cabinet is 50%.
What is his gross profit margin?Gross profit margin is the difference between the revenue and cost of an item divided by the revenue of the same item expressed as a percent.
Revenue refers to the amount a seller sells a particular units of product.
Cost refers to the amount spent by a producer to manufacture a particular unit of a product.
Revenue = $800
Cost = $400
Gross profit margin = (Revenue - Cost) / Revenue × 100
= ($800 - $400) / $800 × 100
= 400/800 × 100
= 50%
Ultimately, 50% is the gross profit margin of the item.

Using Compound Interest, The largest balance is $7802.55, so the option A will give them the largest balance after 5 years.
What is Compound Interest?Even though there are several ways to define an investor, compound interest helps investors. When banks lend money and utilize the income they earn to finance other loans, for instance, they profit from compound interest. When depositors earn interest on their bank accounts, bonds, or other investments, compound interest benefits them.

Ten pounds of mixed birdseed sells for $6.70 per pound. The mixture is obtained from two kinds of birdseed, with one variety priced at $5.77 per pound and the other at $8.87 per pound. How many pounds of each variety of birdseed are used in the mixture?
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.

I need this byh tonigth aswell please help
Answer:
x = 40°
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°
25° + x + 115° = 180°
x + 140° = 180° ( subtract 140° from both sides )
x = 40°
