Sarah has 273 feet of wire to make bead necklaces. If each necklace requires 1 2/3 feet of wire, how many necklaces can she make?
Oh boy, here we go again
First we must convert 1 2/3 to an improper fraction. By doing this, we get 5/3 (3/3 + 2/3)
So now we have 273 / 5/3
To divide this easier we can do something that when I learned it was called (keep, change, flip) which basically means keep the first fraction, change the sign from division to multiplication, and flip the second fraction
This now turns into: 273/1 * 3/5
Combine 273 and 3/5
273⋅3/5
Multiply 273
by 3
819/5

Answer:
b. The total sum of the money was $330
Step-by-step explanation:
#b
∵ A sum of money is divided among John, Paul, and Robert
∵ The ratio of the shares of John, Paul, and Robert is 2: 4: 5
→ Multiply the ratio of each share by x
∴ The share of John = 2x
∴ The share of Paul = 4x
∴ The share of Robert = 5x
→ Find their sum
∴ The sum of the money = 2x + 4x + 5x = 11x
∵ The sum of the money is divided equally among them
→ That means dividing the sum by 3 to find the share of every one
∵ The sum of the money = 11x
∴ The share of every one = \(\frac{11x}{3}\) = \(\frac{11}{3}\)x
∴ The share of John is larger by $50
→ That means the difference between his shares is 50
∵ \(\frac{11}{3}\)x - 2x = 50
∴ \(\frac{5}{3}\)x = 50
→ Divide both sides by \(\frac{5}{3}\)
∴ x = 30
→ Substitute it in the sum of the money to find it
∵ The sum of the money = 11(30)
∴ The sum of the money = $330
∴ The total sum of the money is $330
Solve the triangle. a = 8.186 in c=6.719 in B=73.15° What is the length of side b? in ___(Round to the nearest thousandth as needed.) What is the measure of angle A? ___(Round to the nearest hundredth as needed.) What is the measure of angle C? ___ (Round to the nearest hundredth as needed.)
The length of side b is approximately 6.437 in, angle A is approximately 24.28°, and angle C is approximately 82.57°.
Given the lengths of sides a = 8.186 in and c = 6.719 in, and angle B = 73.15°, we can solve for the length of side b, as well as the measures of angles A and C.
The length of side b is approximately 6.437 in. Angle A is approximately 24.28°, and angle C is approximately 82.57°.
To solve the triangle, we can use the Law of Sines and the fact that the sum of angles in a triangle is 180°.
Using the Law of Sines, we have:
sin(A) / a = sin(B) / b
sin(A) = (sin(B) * a) / b
sin(A) = (sin(73.15°) * 8.186) / b
We can solve for side b by rearranging the equation:
b = (sin(73.15°) * 8.186) / sin(A)
Substituting the given values, we find:
b = (sin(73.15°) * 8.186) / sin(A)
b ≈ (0.9645 * 8.186) / sin(A)
b ≈ 7.897 / sin(A)
b ≈ 6.437 in (rounded to the nearest thousandth)
Next, we can find angle A:
A = 180° - B - C
A ≈ 180° - 73.15° - 82.57°
A ≈ 24.28° (rounded to the nearest hundredth)
Finally, we can find angle C using the fact that the sum of angles in a triangle is 180°:
C = 180° - A - B
C ≈ 180° - 24.28° - 73.15°
C ≈ 82.57° (rounded to the nearest hundredth)
Therefore, the length of side b is approximately 6.437 in, angle A is approximately 24.28°, and angle C is approximately 82.57°.

implement f using a single 4-to-1 multiplexer and two inverters. (5 points)
The function f can be implemented using a single 4-to-1 multiplexer and two inverters.
A 4-to-1 multiplexer is a digital logic component that selects one of four input signals based on the select lines. It has four data inputs (D0, D1, D2, D3), two select lines (S0, S1), and one output (Y). By properly connecting the inputs and select lines, we can realize the desired function f.
To implement the function f using a single 4-to-1 multiplexer and two inverters, we need to carefully assign the input signals and select lines to achieve the desired behavior. The truth table of the function f will guide us in determining the appropriate connections.
First, we can use the inverters to complement the required inputs if needed. Then, we can connect the complemented and uncomplemented inputs to the select lines of the multiplexer. The output of the multiplexer will be the result of the function f.
By carefully selecting the input assignments and connections, we can effectively implement the function f using a single 4-to-1 multiplexer and two inverters. This approach offers a compact and efficient solution for realizing the desired logic function.

Answer to 1:
\(\frac{x^3}{2y^25}\)
First thing you want to do is combine like terms on the bottom. Since it's multiplication, all you have to do is add the exponents. So for x you'd get x raised to the -9 power and for y you'd get 2y raised to the power of 7
Second thing is the numerator of the fraction. Since this is raising what is inside the paranthesis to a power, you must multiply this power by the powers of x and y, respectively. You should get x raised to the power of -6 and y raised to the power of -18
Here's where it gets complicated. to rationalize the problem, you must add parts from the numerator and denominator or vice versa. You cannot have any negative exponents anywhere in the fraction. So that means for x you have to add 9 to the x on the top to cancel out the -6 and rationalize the remaining x's. You should end up with x^3.
For y, you work the opposite way. Since the negatives are only on the top, you simply add 18 to the bottom y's and it remains rationalized.
If done correctly this should come out to x^3/2y^25
Answer to 2:
(x^20y^12)/256
First thing you can do on this one is to cancel out the x^0s. Anything to the power of 0 equals one so only the coefficients will remain. Multiply those together and you'll get 4.
Next you will rationalize the ys. Add the bottom 3 to the top to cancel out the denominator and you're left with y^-3. Leave it like this for now.
Now is the difficult part. You must take everything that is inside the parenthesis to the power of -4. That includes the coefficients and the exponents. 4^-4 = 1/256. This means that you now must move the coefficients to the bottom. You should currently have y^-3/(256x^5).
Now take the exponents to the power using the same rules as question 1. -3*-4 = 12 and 5*-4 = -20. You should now have y^12/(256x^-20)
Lastly, we must rationalize the denominator. To do so, move the x^-20 to the numerator and make the exponent positive. After doing this, you have the answer: (x^20y^12)/256

What is the solution of the inequality shown
below?
y+7≤-1
The solution to the inequality is y ≤ -8. This means that any value of y that is less than or equal to -8 will satisfy the original inequality.
To solve the inequality y + 7 ≤ -1, we need to isolate the variable y on one side of the inequality sign.
Starting with the given inequality:
y + 7 ≤ -1
We can begin by subtracting 7 from both sides of the inequality:
y + 7 - 7 ≤ -1 - 7
y ≤ -8
The solution to the inequality is y ≤ -8. This means that any value of y that is less than or equal to -8 will satisfy the original inequality.
In the context of a number line, all values to the left of -8, including -8 itself, will make the inequality true. For example, -10, -9, -8, -8.5, and any other value less than -8 will satisfy the inequality. However, any value greater than -8 will not satisfy the inequality.

Find the amount received by him at the c) Mrs. Rai borrowed a sum of Rs 10,800 from Mr. Yadav at the rate of 13% per year. Calculate the amount received by Mr. Yadav in 9 months.
Mr. Yadav received Rs 12,204 from Mrs. Rai after 9 months.
To calculate the amount received by Mr. Yadav when Mrs. Rai borrows Rs 10,800 at an annual interest rate of 13% for 9 months, we need to consider the concept of simple interest.
Simple interest is calculated using the formula:
\(I = P \times R \times T,\)
where I is the interest, P is the principal amount, R is the rate of interest per year, and T is the time period in years.
In this case, the principal amount (P) is Rs 10,800, the rate of interest (R) is 13% per year, and the time period (T) is 9 months, which is equivalent to 9/12 or 3/4 years.
Now we can substitute these values into the formula to calculate the interest:
\(I = 10,800 \times 0.13 \times (3/4) = 1,404.\)
The interest earned by Mr. Yadav is Rs 1,404.
To find the amount received by Mr. Yadav, we add the interest to the principal:
Amount = Principal + Interest = 10,800 + 1,404 = 12,204.

Answer:
30°
Step-by-step explanation:
We know that the angles in triangles always add up to 180°. There is also a right angle in this triangle, which is 90°.
Using this policy, we can assume that:
(3x - 30) + x + 90 = 180
First, we need to combine like terms. We can combine the 3x and the x, and the -30 and the 90.
4x + 60 = 180
Subtract 60 from both sides.
4x = 120
Divide by 4 on both sides.
x = 30

Step-by-step explanation:
5. Given f(t) = u(t), g(t) = 2tu(t), and g(t) = f(t - 1)* g(t), determine q(4). 6. Given f(t) = u(-t), h(t) = tu(-t), and y(t) = f(t) *h(t), determine y(-4) and y(4). *
g(4) = 1 * g(4), which means that q(4) is equal to g(4). y(-4) = f(-4) * h(-4) = 1 * (-4) = -4. Therefore, the values of q(4), y(-4), and y(4) are determined as follows: q(4) = g(4), y(-4) = -4, and y(4) = 0.
For the first part of the problem, we are given f(t) = u(t), g(t) = 2tu(t), and g(t) = f(t - 1) * g(t). To determine q(4), we need to substitute t = 4 into the equation g(t) = f(t - 1) * g(t). This gives us g(4) = f(3) * g(4). Since f(t) = u(t), we know that f(3) = u(3) = 1 because u(t) is a unit step function that equals 1 for t ≥ 0. Therefore, we have g(4) = 1 * g(4), which means that q(4) is equal to g(4).
For the second part of the problem, we are given f(t) = u(-t), h(t) = tu(-t), and y(t) = f(t) * h(t). To determine y(-4) and y(4), we substitute t = -4 and t = 4 into the equation y(t) = f(t) * h(t). For y(-4), we have y(-4) = f(-4) * h(-4). Since f(t) = u(-t), we have f(-4) = u(4) = 1 because u(t) is a unit step function that equals 1 for t ≥ 0. Similarly, h(-4) = -4u(4) = -4. Therefore, y(-4) = f(-4) * h(-4) = 1 * (-4) = -4.
Similarly, for y(4), we have y(4) = f(4) * h(4). Since f(t) = u(-t), we have f(4) = u(-4) = 0 because u(t) is a unit step function that equals 0 for t < 0. Thus, y(4) = f(4) * h(4) = 0 * h(4) = 0.
Therefore, the values of q(4), y(-4), and y(4) are determined as follows: q(4) = g(4), y(-4) = -4, and y(4) = 0.

5. Saili plants 4 saplings, in a row, in her garden. The distance between two adjacent
saplings is3/4
m. Find the distance between the first and the last sapling.
The distance between the first and last sapling is 3/4 * 3 = 9/4 m or 2.25 m.
To explain how to find the distance between the first and last sapling, we need to understand the given information. Saili plants 4 saplings in a row, and the distance between two adjacent saplings is 3/4 m.
Since the distance between each adjacent sapling is 3/4 m, we can calculate the total distance by multiplying this distance by the number of intervals between the saplings. In this case, there are 3 intervals between the 4 saplings.
To find the total distance, we multiply the distance between each interval (3/4 m) by the number of intervals (3):
(3/4) * 3 = 9/4 m or 2.25 m.
Therefore, the distance between the first and last sapling is 9/4 m or 2.25 m. This means that if we measure the distance from the first sapling to the last sapling, it will be 9/4 m or 2.25 m in length.

2.15 is value of binomial distribution and 2.15 is value of standard deviation.
In statistics, what is a binomial distribution?
The possibility that a variable would take one of two independent values under a certain set of factors or assumptions is expressed by the statistical distribution known as the binomial distribution.
As an illustration, there are only two conceivable results from tossing a coin: heads or tails, and there are only two outcomes from taking a test: success or failure. The term "binomial probability distribution" is sometimes used to describe this distribution.
Given that,
p = 0.2
q = 1 - p =1-0.2=0.8
n = 29
