Find the cost of buying 150 stamps using the table above=
Find the cost of buying 213 stamps with the table above=
Step-by-step explanation:
For a 151kg parcel, we can see that it falls under the category of "Over 100kg and up to 500kg", so the cost would be 21.10 Naira per kg:
Cost of sending 151kg parcel = 21.10 Naira/kg * 151 kg = 3187.10 Naira
For a 507kg parcel, we can see that it falls under the category of "Over 100kg and up to 500kg", so the cost would be 21.10 Naira per kg:
Cost of sending 507kg parcel = 21.10 Naira/kg * 507 kg = 10701.70 Naira
To find the cost of buying stamps, we need to check which category the number of stamps falls under. For 150 stamps, it falls under the category of "Over 10 stamps up to 50 stamps", so the cost would be 75.00 Naira:
Cost of buying 150 stamps = 75.00 Naira
For 213 stamps, it falls under the category of "Over 50 stamps up to 100 stamps", so the cost would be 105.00 Naira:
Cost of buying 213 stamps = 105.00 Naira

Sophia takes guitar lessons at home every Sunday. Her instructor charges $15 to cover home visit costs, and $30 per hour of training. One Sunday, Sophia's mother pays the instructor $75 for the guitar lessons.
Select the equation that represents the given situation and find the number of hours of Sophia's lesson.
A.
15x + 30 = 75; 3 hours
B.
15x + 30 = 75; 2 hours
C.
30x + 15 = 75; 2 hours
D.
30x + 15 = 75; 3 hours
In a linear equation,The equation to represent the situation is y = 15 + 30x.
The number of hours Sophia used for the guitar training after paying 75 dollars is 2 hours.
What in mathematics is a linear equation?
An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation. The variables in the previous sentence, y and x, are referred to as a "linear equation with two variables" at times.
Sophia's mother pays the instructor $75 for the guitar lessons.
The equation that can be used to represent the given situation is as follows:
let
x = number of hours used for the training
y = total cost
Therefore,
y = 15 + 30x
Now, Sophia's mother spent 75 dollars for her daughters training. Let's find the hours Sophia used.
Therefore,
75 = 15 + 30x
75 - 15 = 30x
60 = 30x
divide both sides by 30
x = 60 / 30
x= 2
Therefore, she used 2 hours for the training.

4 to the 3 power, x 4 to the 4th power, divide by 4 to the 9th power
Answer:
We can simplify the expression as follows:
4^3 * 4^4 / 4^9
First, we can simplify the terms in the numerator by adding the exponents of 4:
4^3 * 4^4 = 4^(3+4) = 4^7
Now, we can substitute this value in the expression:
4^7 / 4^9
To divide powers with the same base, we can subtract their exponents:
4^(7-9) = 4^(-2)
Therefore, the simplified expression is:
4^3 * 4^4 / 4^9 = 4^(-2)
So, the final answer is 1/16 or 0.0625.

How to factor the equation to find dimensions?The area of the rectangular rug is given by the trinomial:
[tex]$r^2 - 8r - 33$[/tex]
To find the possible dimensions of the rug, we need to factor this trinomial. We can do this by finding two numbers that multiply to -33 and add up to -8. These numbers are -11 and 3:
[tex]$r^2 - 8r - 33 = (r - 11)(r + 3)$[/tex]
Therefore, the possible dimensions of the rug are:
[tex]$r - 11 = 0$[/tex] or [tex]$r + 3 = 0$[/tex]
[tex]$r = 11$[/tex]or $[tex]$r = -3$[/tex]
Since the dimensions of the rug cannot be negative, we can only take the positive value of r, which is r = 11.

The value of x that maximizes the area of the figure is 1.5 inches, and the maximum area is 3.375 square inches.
What is rectangle ?A rectangle is a two-dimensional form that has four full sides and four right angles. Because the opposing sides are parallel and congruent, it is a unique kind of parallelogram.
To find the maximum area of the figure, we need to determine the value of x that will maximize the area.
The area of the figure can be calculated as:
A = (1.5x)(x) + (1/2)(1.5x)(6-2x)
Simplifying the expression:
[tex]A = 1.5x^2 + 4.5x - 3x^2[/tex]
[tex]A = -1.5x^2 + 4.5x[/tex]
To find the value of x that maximizes the area, we need to take the derivative of A with respect to x and set it equal to zero:
dA/dx = -3x + 4.5 = 0
Solving for x:
3x = 4.5
x = 1.5 inches
Now that we know x=1.5 inches maximizes the area, we can substitute it back into the area equation to find the maximum area:
[tex]A = -1.5(1.5)^2 + 4.5(1.5)[/tex]
A = 3.375 square inches
Therefore, the value of x that maximizes the area of the figure is 1.5 inches and the maximum area is 3.375 square inches.

e. What is the probability that a randomly selected seedless watermelon will weigh between 5.3 and 6 kg?
f. The 85th percentile for the weight of seedless watermelons is
Answer:
a. X ~ N(6.1, 1.2^2)
b. The median seedless watermelon weight is 6.1 kg.
c. The Z-score for a seedless watermelon weighing 7 kg is 0.75.
d. The probability that a randomly selected watermelon will weigh more than 5.1 kg is 0.7967.
e. The probability that a randomly selected seedless watermelon will weigh between 5.3 and 6 kg is 0.2454.
f. The 85th percentile for the weight of seedless watermelons is 7.2437 kg.
Step-by-step explanation:
a. X ~ N(6.1, 1.2^2)
b. The median of a normal distribution is equal to the mean, so the median seedless watermelon weight is 6.1 kg.
c. The Z-score for a seedless watermelon weighing 7 kg can be calculated as:
Z = (7 - 6.1) / 1.2 = 0.75
Therefore, the Z-score is 0.75.
d. To find the probability that a randomly selected watermelon will weigh more than 5.1 kg, we need to standardize the value using the formula:
Z = (X - μ) / σ
where X is the value we want to find the probability for, μ is the mean, and σ is the standard deviation.
Z = (5.1 - 6.1) / 1.2 = -0.8333
Using a standard normal distribution table or a calculator, we can find the probability that Z is greater than -0.8333 to be 0.7967.
Therefore, the probability that a randomly selected watermelon will weigh more than 5.1 kg is 0.7967.
e. To find the probability that a randomly selected seedless watermelon will weigh between 5.3 and 6 kg, we need to standardize the values and find the area under the normal curve between the two Z-scores. The Z-scores for 5.3 kg and 6 kg are:
Z1 = (5.3 - 6.1) / 1.2 = -0.6667
Z2 = (6 - 6.1) / 1.2 = -0.0833
Using a standard normal distribution table or a calculator, we can find the probability that Z is between -0.6667 and -0.0833 to be 0.2454.
Therefore, the probability that a randomly selected seedless watermelon will weigh between 5.3 and 6 kg is 0.2454.
f. The 85th percentile for the weight of seedless watermelons can be found by finding the Z-score that corresponds to the 85th percentile of a standard normal distribution. Using a standard normal distribution table or a calculator, we can find the Z-score to be 1.0364.
To find the corresponding weight, we can use the formula:
Z = (X - μ) / σ
1.0364 = (X - 6.1) / 1.2
X = 7.2437
Therefore, the 85th percentile for the weight of seedless watermelons is 7.2437 kg.

b) 6.1
c) 0.75
d) 0.7977 (or 79.77%)
e) 0.2143 (or 21.43%)
f) 7.3435 kg (using excel) or 7.348 kg (using normal tables)
Step-by-step explanation:
a) normal distribution just need to be define we his mean and his standard deviation. You just need a sample higher than 30 or to be specified the population is normally distributed
X≈N(μ,σ)= N(6.1,1.2)
b) The median and mean are not necessarily the same, for a normal distribution, which is a symmetric distribution, those values are just the same
c) The equation for Z score is given by:
[tex]z=\frac{x-u}{\sigma}[/tex]
Replacing values:
[tex]Z=\frac{7-6.1}{1.2} =0.75[/tex]
d) first find the Zvalue for 5.1
[tex]Z=\frac{5.1-6.1}{1.2} =-0.83[/tex]
Now, find the probability from Normal Distribution table
P(Z>0.83) = 0.7977
e)
first find the Zvalue fo5.3 and 6
[tex]Z=\frac{5.3-6.1}{1.2} =-0.67[/tex]
[tex]Z=\frac{6-6.1}{1.2} =-0.08[/tex]
Now find probabilities from Normal Distribution table . Notice you need to subtract P(Z>0.08)-P(Z>0.67) if you use a positive table.
P(-0.67<z<-0.08) = 0.2143
f) Find the Z score from a Normal Distribution table that give you an area of 0.8500 (or the closest value), im using excel for this one since the answer from tables have only TWO decimals and can be problematic if you need more decimal places.
this gives a Z of 1.036433389
now use the Zscore equation but solve for X
[tex]z\sigma+u=x[/tex]
x = 1.036433389(1.2)+6.1 = 7.3437 (Using excel)
If i use a table, the closes is 1.04 (0.8508 which is not exactly 0.85)
x = 1.04(1.2)+6.1= 7.348 (using table)
so be carefully with the input if the website needs the decimals places or not.

-9x + 3y = 27
-3x + 4y = 24
The slope of the equation -9x + 3y = 27 is greater and this line has a greater rate of change.
What is rate of change?The pace at which one quantity changes in relation to another quantity is known as the rate of change function. Simply said, the rate of change is calculated by dividing the amount of change in one thing by the equal amount of change in another. In the slope-intercept form for a line, the rate of change m for a linear function is written as y=mx+b, whereas the rate of change of functions is defined as (f(b)-f(a))/b-a.
The standard equation of the line is given as:
y = mx + c
where, m is the slope of the line.
For the given equation of lines, transform them into standard equation:
-9x + 3y = 27
3y = 9x + 27
Divide both sides of the equation with 3:
y = 3x + 9
Here, the slope of the equation is 3.
For, -3x + 4y = 24
4y = 3x + 24
Divide both sides of the equation by 4:
y = 3/4x + 6
The slope of this line is 3/4.
Comparing the slope of the two lines we see that,
3 > 3/4
Hence, the slope of the equation -9x + 3y = 27 is greater and this line has a greater rate of change.

However, if the question is x^2 - x - 20 = 0,
x = 4, -5
Step-by-step explanation:
WARNING: Your question is incorrect and so, I have tweaked it to make it correct
Completing the square of (x^2 + x - 20):
(x^2 - x) - 20
= (x^2 - x + (1/2)^2 - (1/2)^2) - 20
= (x^2 - x + (1/4))^2 - 1/4 - 20

Hence,
(x-1/2)^2 - 81/4 = 0
(x-1/2)^2 = 81/4
x-1/2 = + or - 9/2
x = 9/2 + 1/2 (OR) x = -9/2 + 1/2
x = 5 (OR) x = -4

If $f(x)=4x^3+1$, find $f^{-1}(33)$.
The value of the inverse function of f(x), that is, f⁻¹(33) is 2.
How is the inverse function of a given function found?A function takes in values, applies specific operations to them, and produces an output. The inverse function acts, agrees with the outcome, and returns to the initial function. In general, switching the coordinates x and y is how an inverse is calculated. Although not strictly a function, this freshly constructed inverse is a relation.
To guarantee that the original function's inverse will likewise be a function, the original function must be a one-to-one function. Only when every second element matches the first value is a function deemed to be a one-to-one function.
Given that,
f(x)=4x³+1
Also, f⁻¹(33).
Thus, using the input and output corresponding values we have:
f(x) = 4x³ + 1 = 33
x³ = 8
Taking the cube root of both sides, we get:

Here,
A function's difference quotient, f(x), is provided by:
=> [f(x+ h) - f(x)] / h
where h denotes a slight modification to the x-value.
The difference quotient for the function f(x) = -3/x can be calculated as follows:
=> [f(x + h) - f(x)] / h
=> [-3/√(x + h) + 3/√x] / h (substituting x + h for x in the function)
=> [-3√x + 3√(x + h)] / [h√x√(x + h)] (finding a common denominator and combining the terms)
=> [-3√x + 3√(x + h)] / h / √x√(x + h) (dividing by the denominator)
Therefore, the difference quotient of f(x) is:
=> [-3√x + 3√(x + h)] / h / √x√(x + h)
The difference fraction of f(x) is thus:
=> [-3√x + 3√(x + h)] / h / √x√(x + h)

In this case, the preferred alternative is Alternative 1, since it has a present value of $60,623.
What is an investment?An investment is the use of money to buy assets or take part in activities with the expectation of a financial gain or other benefit in the future. It can take many forms, such as purchasing shares, bonds, mutual funds, real estate, artwork, or antiques.
The present value of an investment can be calculated by taking the amount of the future cash flow and discounting it by an appropriate rate of return. In this case, the appropriate rate of return is 15%. The present value of Alternative 1 can be calculated by taking the total cash flows of $105,000 and discounting them by 15%:
Present Value of Alternative 1 = $105,000 / (1 + 0.15)3 + (1 + 0.15)7 = $60,623
The present value of Alternative 2 can be calculated in the same manner:
Present Value of Alternative 2 = $8,000 / (1 + 0.15)7 = $4,923
The discounted cash flow criterion states that the preferred alternative is the one with the higher present value. Therefore, in this case, the preferred alternative is Alternative 1, since it has a present value of $60,623 compared to the present value of Alternative 2, which is $4,923.

Answer:
Reflection only
The mirror line must pass through one of the sides of the triangle.
============================================================
Explanation:
The term "invariant" means "does not vary" i.e. "does not change".
An invariant point is fixed in place.
Here are the list of geometric transformations
Translation (aka shifting)RotationReflectionDilationSome geometry textbooks will mention "glide reflection", but that's really just a combination of translation and reflection. That means we can ignore it.
Let's go through each item to see if we can get two vertices to stay glued in their spot.
With translations, it's impossible to have invariant points. Every point will change location. Therefore, we cannot have two invariant vertices for any translation. We cross translation off the list.Rotations are a little better. We have one point that doesn't move: the center of rotation. Unfortunately every other point that isn't the center will rotate around the center (and hence change location). We cross rotations off the list.Reflections are the transformation that will be able to hold two vertices fixed in place. Any point on the mirror line will not change location. If we draw the mirror line through a side of the triangle, then it will guarantee two vertices will stay in place. This is why reflection is the only answer.Dilations are similar to rotations in that they have one invariant point. The center of dilation stays where it is, but everything else moves closer to the center (if the scale factor is between 0 and 1) or moves away from the center (if the scale factor is larger than 1). We cross dilations off the list.In short we have eliminated: translations, rotations, and dilations. The only thing that works is reflections
Beginning inventory is &12,000 the purchase are $20,000 the ending inventory is $14,000 and other credits are $2,000 what is the actual food cost
Answer:
the actual food cost is $20,000.
Step-by-step explanation:
To calculate the actual food cost, we need to use the following formula:
Actual Food Cost = Beginning Inventory + Purchases - Ending Inventory + Other Credits
Substituting the given values in the formula, we get:
Actual Food Cost = $12,000 + $20,000 - $14,000 + $2,000
Actual Food Cost = $20,000
Therefore, the actual food cost is $20,000.
