Answer: 28
Step-by-step explanation:
16% = 0.16
Percents are just decimals!
Now you can put this in your calculator, and you will get 28.
However:
It might help you later to know that x% of y = y% of x
In other words, 16% of 175 is the same thing as 175% of 16
This problem is easier, since we can break 175% into 1 and 3/4th. 3/4th of 16 is easy to calculate, (its 12), and so we can add 12 to 16 to find the answer, which is still 28 :)

Mrs. Miller would like to create a small vegetable garden adjacent to her house. She has 20 ft of fencing to put around three sides of the garden
The standard form of the quadratic function that represents the area of the garden is: G(x) = - 2x² + 20x
Mrs Miller has 20 ft of fencing to put around three sides of the garden.
Let us assume that l represents the length of the garden.
Here x represents the width of the rectangular garden.
So, l = 20 - 2x
We know that the formula for the area of rectangle is:
A = length × width
Let G(x) be a function that represents the area of the garden.
Using above formula,
G(x) = x × l
G(x) = x(20 - 2x)
G(x) = 20x - 2x²
G(x) = - 2x² + 20x
Therefore, the required quadratic function is: G(x) = - 2x² + 20x

In a lottery, the top cash prize was $693 million, going to three lucky winners. Players pick five different numbers from 1 to 51
and one number from 1 to 42. -
A player wins a minimum award of $400 by correctly matching four numbers drawn from the white balls (1 through 51) and
matching the number on the gold ball (1 through 42). What is the probability of winning the minimum award?
The probability of winning the minimum award is.
(Type an integer or a simplified fraction.)
Answer:
1/237.12.
Step-by-step explanation:
The probability of winning the minimum award can be calculated by multiplying the probability of picking 4 numbers correctly from 1 to 51 and then multiplying by the probability of picking 1 number correctly from 1 to 42.
The probability of picking 4 numbers correctly from 1 to 51 is given by the formula:
(number of combinations of 4 numbers from 51) / (number of combinations of 5 numbers from 51)
= (51 choose 4) / (51 choose 5)
= 51! / (4! * 47!) / (51! / (5! * 46!))
= (51 * 50 * 49 * 48) / (5 * 4 * 47 * 46)
= 19600 / 10,946
= 1/5.6 approximately
The probability of picking 1 number correctly from 1 to 42 is given by the formula:
1/42
The final probability of winning the minimum award is given by multiplying the above two probabilities:
1/5.6 * 1/42 = 1/237.12
So, the probability of winning the minimum award is approximately 1/237.12.

For the two given graphs, the value for vector equation is obtained as [tex]\vec{w} = 2\vec{u} + \vec{v}[/tex].
What is a vector?
A vector in mathematics is a quantity that not only expresses magnitude but also motion or position of an object in relation to another point or object. Euclidean vector, geometric vector, and spatial vector are other names for it.
From first graph it is seen that -
[tex]\vec{u}= < 1,1 >[/tex] and [tex]\vec{v}= < -1,2 >[/tex]
From second graph it is seen that -
[tex]\vec{w}= < 1,4 >[/tex]
So, it is obtained that -
[tex]a\vec{v}+b\vec{u}=\vec{w}[/tex]
Substitute all the values in the equation -
a<-1,2> + b<1,1> = <1,4>
<-a,2a> + <b,b> = <1,4>
<-a+b,2a+b> = <1,4>
The two equation obtained are -
-a + b = 1
2a + b = 4
Subtracting the equation 1 from 2 -
2a + b - (-a + b) = 4 - 1
2a + b + a - b = 3
3a = 3
a = 1
Substitute the value of a in equation 1 -
-1 + b = 1
b = 1 + 1
b = 2
So, the equation [tex]a\vec{v}+b\vec{u}=\vec{w}[/tex] becomes -
[tex]\vec{v} + 2\vec{u} = \vec{w}[/tex]
Therefore, the vector is obtained as [tex]\vec{w} = 2\vec{u} + \vec{v}[/tex].

What is 42−6×4(12) to the third power?
Answer:
Step-by-step explanation:
First, we need to evaluate the expression inside the parenthesis: 4(12) = 4 * 12 = 48.
Next, we can simplify the expression: 42 - 6 * 48 = 42 - 288 = -246.
Finally, we raise the result to the third power: (-246)^3 = (-246) * (-246) * (-246) = -158,048.
So, the result is -158,048.
the weight distribution of packages sent in a certain manner is normal with mean value 12 lb and standard deviation 3.5 lb. the package service wishes to establish a weight value c beyond which there will be a surcharge. what value of c is such that 99% of all packages are at least 1.0 lb under the surcharge weight?
The surcharge weight should be set at 12.25 lb, since 99% of all packages are at least 1.0 lb under this weight.
In this problem, we are given that the weight distribution of packages sent in a certain manner is normal, with a mean value of 12 lb and a standard deviation of 3.5 lb. The standard deviation is a measure of how much the data varies from the mean.
Now, the package service wishes to establish a weight value c, beyond which there will be a surcharge. We want to find the value of c such that 99% of all packages are at least 1.0 lb under the surcharge weight. This means that we are looking for a weight value that is exceeded by only 1% of all packages.
To find this weight value, we can use the properties of the normal distribution. We know that the area under the normal curve represents the probability of an event occurring. In this case, we want to find the weight value c that corresponds to the 1% probability.
To do this, we first need to standardize our normal distribution by converting it to the standard normal distribution, which has a mean of 0 and a standard deviation of 1. We can do this by subtracting the mean (12 lb) from our target weight value c, and then dividing by the standard deviation (3.5 lb). This gives us a z-score, which represents the number of standard deviations away from the mean our target weight value is.
Next, we can use a standard normal distribution table or calculator to find the z-score that corresponds to the 1% probability. This is approximately -2.33.
Finally, we can solve for c by reversing the standardization process. We multiply the z-score (-2.33) by the standard deviation (3.5 lb) and add the mean (12 lb) to get our target weight value c.
Therefore, c = -2.33 x 3.5 + 12 ≈ 0.25 lb.

The polynomial (x-a)(x-b)(x-c)....(x-z) has a coefficient of -351 for the x²⁵ term. Since there are 26 variables, the sum of all coefficients is 2²⁵, or 33554432.
The polynomial (x-a)(x-b)(x-c)....(x-z) can be written as
x²⁶ - (a+b+c+...+z)x²⁶ + (sum of products of pairs)x²⁴ - ... - abc...xyz
The coefficient of x²⁵ is the negative sum of the constants, which is -(a+b+c+...+z). Since there are 26 variables in total, the sum of the constants is just the sum of the first 26 letters of the alphabet, which is
(a+b+c+...+z) = 1 + 2 + 3 + ... + 26 = 351
So the coefficient of x²⁵ is -351.
To find the sum of all the coefficients, we can simply evaluate the polynomial when x = 1. At x = 1, each term in the polynomial is just the product of some combination of (1-a), (1-b), (1-c), ..., and (1-z). Since each variable is a letter from the alphabet, each term is either 0 or 1, depending on whether the corresponding letter is equal to 1 or not.
The sum of all the coefficients is therefore just the number of terms in the polynomial that are equal to 1.
Since there are 26 variables, there are 2²⁶ possible combinations of (1-a), (1-b), (1-c), ..., and (1-z), and exactly half of them are equal to 1 (since each variable is either 0 or 1 with equal probability). Therefore, the sum of all the coefficients is
2²⁵ = 33554432
So the sum of the coefficients of the polynomial (x-a)(x-b)(x-c)....(x-z) is 33554432.

Step-by-step explanation:
This figure is a compound of 3 rectangles that can be split up like in my attached picture.
The top, horizontal rectangle is 8x3 = 24 sq ft.
The bottom, almost square rectangle is 4x5 = 20 sq ft.
The middle rectangle has a height of 4 feet and a width of (8-6) = 2 feet.
So, its area is 4x2= 8 sq ft.
The compound figure is the sum of all of these areas:
24 + 20 + 8 = 52
The area of the compound figure is 52 sq ft.
Area of 1 = 8 * 3 = 24
Area of 2 = 4 * 2 = 8
Area of 3 = 5 * 4 = 20
Total area = 24 + 8 + 20 = 52

Find all six trigonometric functions of θ if the given point is on the terminal side of θ. Answer exactly. ( − 4 , − 1 )
The six trigonometric functions of the angle θ for the given point (-4, -1) are sin θ = -1/5, cos θ = -4/5, tan θ = 1/4, cot θ = -4, sec θ = -5/4, and csc θ = -5.
The six trigonometric functions of an angle θ are sine (sin θ), cosine (cos θ), tangent (tan θ), cotangent (cot θ), secant (sec θ), and cosecant (csc θ). These functions can be used to calculate the coordinates of a point on the terminal side of θ when the angle and one coordinate are known.
For example, if you know the angle θ and one coordinate (in this case, -4) of a point on the terminal side of θ, you can use the six trigonometric functions to calculate the remaining coordinate. In this case, the point is (-4, -1). The sine of θ is equal to the y-coordinate (-1) divided by the hypotenuse (distance from the origin). Therefore, sin θ = -1/5. The cosine of θ is equal to the x-coordinate (-4) divided by the hypotenuse. Therefore, cos θ = -4/5. The tangent of θ is equal to the y-coordinate (-1) divided by the x-coordinate (-4). Therefore, tanθ = -1/-4 = 1/4. The cotangent of θ is equal to the x-coordinate (-4) divided by the y-coordinate (-1). Therefore, cot θ = -4/-1 = -4. The secant of θ is equal to the hypotenuse (distance from the origin) divided by the x-coordinate (-4). Therefore, sec θ = 5/-4 = -5/4. The cosecant of θ is equal to the hypotenuse divided by the y-coordinate (-1). Therefore, csc θ = 5/-1 = -5.So, the six trigonometric functions of the angle θ for the given point (-4, -1) are sin θ = -1/5, cos θ = -4/5, tan θ = 1/4, cot θ = -4, sec θ = -5/4, and csc θ = -5.

The first term of an A. P is 5 and the 10th term is 95 to find S10
The first term of an arithmetic progression is 5 and the 10th term is 95. The sum of the first 10 terms is 455.
The sum of the first 10 terms of an arithmetic progression (A.P.) can be found using the formula:
S_n = n/2 * (2a + (n-1)d)
where a is the first term, d is the common difference, and n is the number of terms.
Given that the first term is 5 and the 10th term is 95, we can find the common difference (d) using the formula:
a_n = a + (n-1)d
Plugging in n = 10 and a = 5, we get:
95 = 5 + (10 - 1)d
Solving for d, we get:
d = (95 - 5) / (10 - 1) = 9
Now that we know the common difference, we can find the sum of the first 10 terms:
S_10 = 10/2 * (2 * 5 + (10 - 1) * 9) = 10/2 * (10 + 81) = 10/2 * 91 = 455
So, the sum of the first 10 terms is 455.

David biked 12\frac{7}{8}12
8
7
miles on Tuesday and 5\frac{3}{8}5
8
3
miles on Wednesday.
How much farther did David bike on Tuesday than on Wednesday?
David biked [tex]7\frac{1}{2}[/tex] miles farther on Tuesday than on Wednesday.
We are given that David biked [tex]12\frac{7}{8}[/tex] miles on Tuesday and [tex]5\frac{3}{8}[/tex] miles on Wednesday.
In order to find the number of miles David biked farther on Tuesday than on Wednesday, we will subtract the miles biked by him on Wednesday from the miles biked by him on Tuesday as follows -
[tex]12\frac{7}{8} - 5\frac{3}{8}[/tex]
So, first, we will subtract the whole number of parts as follows -
12-5 = 7
Then, we will subtract the fractional parts as follows -
7/8 - 3/8 = 4/8 = 1/2
so we get,
[tex]12\frac{7}{8} - 5\frac{3}{8} = 7\frac{1}{2}[/tex]
Therefore, David biked [tex]7\frac{1}{2}[/tex] miles farther on Tuesday than on Wednesday.

Andy pays £12. 30 for 6 sketch pad. Jo pays £10 for 2 sketch pads and 1 book. What is the cost of the book?
After solving the expression from the given data we get that the cost of the book is £5.90.
Let's assume the cost of the book is "b" in pounds. From the information given, we can set up the following system of equations:
6x = 12.30 (Andy pays £12.30 for 6 sketch pads)
2x + b = 10 (Jo pays £10 for 2 sketch pads and 1 book). where x is the cost of one sketch pad in pounds. Solving the first equation for x, we get: x = 12.30/6 = 2.05
Substituting this value of x into the second equation, we get: 2(2.05) + b = 10
Simplifying this equation, we get: 4.10 + b = 10
Solving for b, we get: b = 5.90
Therefore, the cost of the book is £5.90.
