What is the surface area of a cone with a 6 in. diameter and a length (slant height) of 8 in.?
The formula of a surface area of a cone:
[tex]SA=pi rl+\pi r^2[/tex]
r - radius
l - slant height
We have the diameter d = 6 in and a slant height l = 8 in.
[tex]d=2r\to r=6in:2=3in[/tex]
Substitute:
[tex]SA=\pi(3)(8)+\pi(3^2)=24\pi+9\pi=\boxed{33\pi\ in^2}[/tex]

Dawn is verifying the accuracy of her paycheck. She earns $12 an hour and works 40 hours each week. Herr biweekly deductions are Social Security 6.2%. Medicare 1.45%, federal withoutholding tax $73.25, state withholding tax $22.50, and health insurance $37.47. What is her net pay if she is paid biweekly?
Answer: $ 753.34
Step-by-step explanation:
Since, here She earns $12 an hour and works 40 hours each week.
Therefore, her earning in two weeks = 2 × 12 × 40 = $ 960
Now, Her biweekly deductions are Social Security 6.2%. Medicare 1.45%, federal with out holding tax $73.25, state withholding tax $22.50, and health insurance $37.47.
Therefore, Her total deduction = (6.2+1.45)% of 960 + (73.25+22.50+37.47)= 73.44+133.22= 206.66
Since, Net pay is the amount of payee after deductions have been taken from the his gross pay.
Therefore, Net pay = total amount - total deduction = 960 - 206.66 = $ 753.34
Her net pay if she is paid biweekly is $ 753.34.
we have given that,
She earns $12 an hour and works 40 hours each week.
Therefore, her earning in two weeks,
= 2 × 12 × 40
= $ 960
Her biweekly deductions are Social Security 6.2%. Medicare 1.45%, federal with out holding tax $73.25, state withholding tax $22.50, and health insurance $37.47.
Therefore,
[tex]Her total deduction = (6.2+1.45)% of 960 + (73.25+22.50+37.47)\\\\\\\\Her total deduction= 73.44+133.22\\ \Her total deduction= 206.66[/tex]
What is the net pay amount formula ?Net pay is the amount of payee after deductions have been taken from the his gross pay.
Net pay = total amount - total deduction
Therefore by using formula,
Net pay= 960 - 206.66
Net pay = $ 753.34

What is the value of X?
If all angles have the same measure, then this is an equilateral triangle.
Therefore we have the equation:
4x - 30 = 3x - 5 add 30 to both sides
4x = 3x + 25 subtract 3x from both sides
x = 25
Check:
|AB| = 3x - 5 → |AB| = 3(25) - 5 = 75 - 5 = 70
|BC| = 2x + 20 → |BC| = 2(25) + 20 = 50 + 20 = 70
|AC| = 4x - 30 → |AC| = 4(25) - 30 = 100 - 30 = 70

Answer: x = 25In a rectangle, the ratio of the length to the width is 5 : 2. The length of the rectangle is 13.875 feet greater than the width. What are the perimeter and the area of the rectangle?
Answer:
Perimeter = 64.75 ft
Area = 213.91 ft
Step-by-step explanation:
13.875 ÷ 3 = 4.625
4.625 x 5 = 23.125 ft (This is the length of the rectangle)
4.625 x 2 = 9.25 ft (This is the width of the rectangle)
(23.125 x 2) + (9.25 x 2) = 64.75 ft (Perimeter)
23.125 x 9.25 = 213.90625 ft, or 213.91 ft if rounded to 2 d.p (Area)
The perimeter of the rectangle is approximately 64.75 feet and the area is approximately 213.91 square feet.
How to solve for the area and perimeter[tex]\[L = W + 13.875\][/tex]
We can use these two equations to solve for the values of \(L\) and \(W\).
First, let's use the ratio to set up an equation:
[tex]\[\frac{L}{W} = \frac{5}{2} \implies L = \frac{5}{2}W\][/tex]
Next, substitute this expression for L into the second equation:
[tex]\[\frac{5}{2}W = W + 13.875\][/tex]
Solving for w
[tex]\[\frac{3}{2}W = 13.875\][/tex]
[tex]\[W = \frac{2}{3} \times 13.875\][/tex]
[tex]\[W = 9.25\][/tex]
Now, use this value of \(W\) to find the length \(L\):
[tex]\[L = \frac{5}{2} \times 9.25 = 23.125\][/tex]
Now that we have the dimensions, we can calculate the perimeter and area:
1. perimeter of a rectangle with length \(L\) and width \(W\) is given by:
[tex]\[P = 2(L + W)\][/tex]
Substituting the values:
[tex]\[P = 2(23.125 + 9.25) \approx 64.75 \text{ feet}\][/tex]
2. Area of a rectangle is given by:
[tex]\[A = L \times W\][/tex]
Substituting the values:
[tex]\[A = 23.125 \times 9.25 \approx 213.91 \text{ square feet}\][/tex]
So, the perimeter of the rectangle is approximately 64.75 feet and the area is approximately 213.91 square feet.

S is a geometric sequence. (Square root x-1),1 and (square root x+1) are the first three terms of s. Find the value of x.
Answer:
x = ± [tex]\sqrt{2}[/tex]
Step-by-step explanation:
given the 3 terms of a geometric sequence
[tex]\sqrt{x-1}[/tex], 1, [tex]\sqrt{x+1}[/tex], then the common ratio r
r = [tex]\frac{\sqrt{(x+1)} }{1}[/tex] = [tex]\frac{1}{\sqrt{(x-1)} }[/tex] ( cross- multiply )
[tex]\sqrt{(x+1)(x-1)}[/tex] = 1 ( square both sides )
(x + 1 )(x - 1 ) = 1 ← expand factors on left side )
x² - 1 = 1 ( add 1 to both sides )
x² = 2 ( take the square root of both sides )
x = ± [tex]\sqrt{2}[/tex]
The value of x is ±[tex]\sqrt{2}[/tex].
What is a Geometric Sequence?It is a sequence, where the ratio of two consecutive terms in a sequence are constant.It is a finite or infinite sequence.Geometric Sequence G is given by: G = a, ar², ar³,..... (a = first term; r = constant ratio)Given:
Geometric Sequence with first three terms.
[tex]\sqrt{x-1},1, \sqrt{x+1[/tex]
We have to find the value of x.
Now, if the given sequence is geometric then we can find the common ratio of the sequence.
The common ratio is given by:
r = [tex]\frac{1}{\sqrt{x-1} }[/tex] and r = [tex]\frac{\sqrt{x+1} }{1}[/tex]
Now, we can equate the both the values of r to solve for the value of x.
[tex]\frac{\sqrt{x+1} }{1} = \frac{1}{\sqrt{x-1} }[/tex]
Now, multiplying the numerator on both sides by [tex]\sqrt{x-1}[/tex], we get:
[tex]\sqrt{x+1} \sqrt{x-1} =1[/tex]
[tex]\sqrt{(x-1)(x+1)}=1[/tex]
[tex]\sqrt{x^2-1} =1[/tex]
Now, squaring on both sides of the equation, we get:
⇒ x² - 1 = 1
⇒ x² = 2
Now, taking square root on both the sides, we get:
⇒ x = ±[tex]\sqrt{2}[/tex]
Therefore, for a given geometric sequence the value of x will be ±[tex]\sqrt{2}[/tex].

c. Check by finding the revenue and the cost for each number of tapes and subtracting to find profit
Answer: p(x) = 8.7x - 1940
p(500) = $2410
p(1000) = $6760
p(5000) = $41,560
Step-by-step explanation:
p(x) = r(x) - c(x)
= 9.5x - (0.8x + 1940)
= 9.5x - 0.8x - 1940
= 8.7x - 1940
**********************************************************************
p(500) = 8.7(500) - 1940
= 4350 - 1940
= 2410
p(1000) = 8.7(1000) - 1940
= 8700 - 1940
= 6760
p(5000) = 8.7(5000) - 1940
= 43,500 - 1940
= 41,560
***************************************************************************
p(500) = r(500) - c(500)
= 9.5(500) - [0.8(500) + 1940]
= 4750 - (400 + 1940)
= 4750 - 2340
= 2410
p(1000) = r(1000) - c(1000)
= 9.5(1000) - [0.8(1000) + 1940]
= 9500 - (800 + 1940)
= 9500 - 2740
= 6760
p(5000) = r(5000) - c(5000)
= 9.5(5000) - [0.8(5000) + 1940]
= 47500 - (4000 + 1940)

If x, y and z each represent a different digit from 0 to 9, what is the value of (x)(y)(z)?
By analyzing the equation and using provided options, we find that the right values for the digits x, y, and z are 1, 2, and 3 respectively. When multiplied together, the product (x)(y)(z) equals 6.
Explanation:The mathematical problem you've presented is akin to a simple addition of numbers, but with a twist: the digits x, y, and z each represent different unknown digits. Our task is to determine the value of the product (x)(y)(z) given the vertical addition:
4zLooking at the addition, we can see that when we add the second digit of the second row (2) with the first digit of the third row (x), the result must be a digit with a 1 carried over because there is a 1 in the hundred's place of the result. That means 2 + x has to be equal to 10 or 11 (since x is a digit, the highest value for x could be 9).
Using the option provided (d) x. 1, y. 2, z. 3, we can see that the column with z's would sum to 7 (4z), the column with x's would sum to 11 (since 1 + x = 11, x = 1), and the column with y's would sum to 14 (since y would then be 2) which fits the pattern of the problem provided. Therefore, the values for x, y, and z are 1, 2, and 3 respectively.
The value of (x)(y)(z) is thus 1 × 2 × 3 = 6.
Final answer:
To find the value of (x)(y)(z), we need to solve the equation 4z/27 + x5/y14 = 0. By substituting different values for x, y, and z, we find that (x)(y)(z) = 6.
Explanation:
To find the value of (x)(y)(z), we need to solve the given equation:
4z/27 + x5/y14 = 0
Since x, y, and z each represent a different digit from 0 to 9, we can try different values to solve for (x)(y)(z).
Let's start with the first term: 4z/27. The only possible value for z is 2, because 4z/27 must give us a rational number. So, let's substitute z = 2 into the equation:
4(2)/27 + x5/y14 = 0
8/27 + x5/y14 = 0
Next, let's solve for the second term: x5/y14. To make this term equal to 0, we can set x = 1 and y = 3. Substituting these values into the equation:
8/27 + 15/314 = 0
Now, let's find the value of (x)(y)(z) = (1)(3)(2) = 6.
