An adult with a weight of 75 kilograms have an equivalent weight of 165.60 pounds.
How to convert kilograms to pounds
Herein we have an application of unit conversions between weight units, from kilograms to pounds. Unit conversions follow this direct proportional formula:
y = k · x
Where:
x - Weight in kilograms
y - Weight in pounds
k - Conversion ratio
If we know that x = 75 kg and k = 2.208 lb/kg, then the weight of the adult in pounds is:
y = (2.208 lb/kg) · (75 kg)
y = 165.6 lb
An adult with a weight of 75 kilograms have an equivalent weight of 165.60 pounds.

Write an equation of a circle with the given center and radius
Center(-7,-6) Radius = 2
The equation of the circle is (x + 7)² + (y + 6)² = 4 if the center and radius are (-7,-6) and 2 respectively.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have center of the circle(h, k) = (-7, -6)
The radius of the circle r = 2
The standard form of a circle:
(x - h)² + (y - k)² = r²
(x - (-7))² + (y - (-6))² = 2²
(x + 7)² + (y + 6)² = 4
Thus, the equation of the circle is (x + 7)² + (y + 6)² = 4 if the center and radius are (-7,-6) and 2 respectively.

Recently, a certain bank offered a 10 year CD that earns 2.97% compounded continuously.
Use the given information to answer the questions:
Using continuous compounding, it is found that:
a) The account will be worth $26,916.31 in 10 years.
b) It will take 42.18 years for the account to be worth $70,000.
What is compound interest?The amount of money earned, in continuous compounding, after t years, is given by:
[tex]A(t) = Pe^{rt}[/tex]
In which:
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value).The parameters are given as follows:
A(0) = 20000, r = 0.0297, t = 10.
Hence the worth in 10 years will be given by:
[tex]A(t) = Pe^{rt}[/tex]
[tex]A(10) = 20000e^{0.0297 \times 10}[/tex]
A(10) = $26,916.31.
Now, we find in how many years it will be worth $70,000, as follows:
[tex]A(t) = Pe^{rt}[/tex]
[tex]70000 = 20000e^{0.0297t}[/tex]
[tex]e^{0.0297t} = 3.5[/tex]
[tex]\ln{e^{0.0297t}} = \ln{3.5}[/tex]
[tex]0.0297t = \ln{3.5}[/tex]
[tex]t = \frac{\ln{3.5}}{0.0297}[/tex]
t = 42.18 years.

Lydia has half of her investments in stock paying an 11% dividend and the other half in a stock paying 14% interest. If her total annual interest is $440, how much does she have invested?
Answer
Based on the calculations, the amount of money she invested is equal to $3,520.
How to determine the amount invested?First of all, we would assign variables to the amount of money that he invested at different interest rates as follows:
Let x be the amount of money she invested at 11%.Let y be the amount of money she invested at 14%.Since Lydia invested the same amount of money in both stocks, we have:
x = y ....equation 1.
At the two interest rates, the total amount Lydia gets is given by:
0.11x + 0.14y = 440 ....equation 2.
Solving the equations simultaneously, we have:
0.11y + 0.14y = 440
0.25y = 440
y = 440/0.25
y = $1,760.
Thus, the total investment is given by:
Total investment = 1760 + 1760
Total investment = $3,520.

The diameter of a wrecking ball used to tear down buildings is 3.5 ft. What is the volume ( to the nearest hundredth) Use 3.14 for pi and round each approximation to the nearest hundredth.
Answer:
22.44 ft
Step-by-step explanation:
The radius is equal to half of the diameter or 1.75 ft (in this case).
The volume of a sphere is defined as the equation:
V = 4/3 * pi * radius ^ 3
V = 4/3 * 3.14 * 1.75 ^ 3
V = 4/3 * 3.14 * 5.36

WHY IS THAT THE LINEAR EQUATION
Linear functions are those whose graph is a straight line. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y
WHAT IS THE NONLINEAR EQUATION
Y = x(3x+2)
WHY IS THAT THE LINEAR EQUATION
A nonlinear function has more than one independent variable. The independent variable is x.
y= x(3x-2) is non linear equation.
y= x/3 + 2 is linear equation.
y= 3 -2x is linear equation.
What is Linear Equation?Linear equations are the equations of degree 1.
It is the equation for the straight line.
The standard form of linear equation is ax+by+c =0, where a ≠ 0 and b ≠ 0.
We know that the linear equation have highest degree 1.
First, y= x(3x-2)
y= 3x² -2x
Here, the highest degree is 2 which is non linear equation.

The area of the right triangle shown is 24 square feet. Which equations can be used to find the lengths of the legs of the triangle? Select three options. 0.5(x)(x + 2) = 24 x(x + 2) = 24 x2 + 2x – 24 = 0 x2 + 2x – 48 = 0 x2 + (x + 2)2 = 100
The equations to calculate the legs are 0.5(x)(x + 2) = 24, x^2 + 2x - 48 = 0 and x^2 + (x + 2)^2 = 100
How to determine the legs of the triangle?The complete question is in the attached image
The given parameters are:
Area = 24
Legs = x and x + 2
The area of the triangle is calculated as:
Area = 0.5 * Base * Height
This gives
0.5 * x * (x + 2) = 24
So, we have:
0.5(x)(x + 2) = 24
Divide through by 0.5
(x)(x + 2) = 48
Expand
x^2 + 2x = 48
Subtract 48 from both side
x^2 + 2x - 48 = 0
Hence, the equations to calculate the legs are 0.5(x)(x + 2) = 24, x^2 + 2x - 48 = 0 and x^2 + (x + 2)^2 = 100

You work as an assistant for a local musical theatre group, the Main Street Theatre Company. The company is putting on a production of Les Misérables this year, and they need your help planning it.
The company's first task is to cast the lead female roles of Fantine, adult Cosette, and Éponine, and the lead male roles of Jean Valjean, Inspector Javert, and Marius. You have received headshots and resumes from 28 women and 22 men who are interested in auditioning for these parts.
A: If no one has been cast yet, how many different ways are there to cast Jean Valjean from the 22 men?
B: If Jean Valjean has already been cast, how many different ways are there to cast Inspector Javert from the remaining men?
C: If Jean Valjean and Inspector Javert have already been cast, how many different ways are there to cast Marius from the remaining men?
Select one answer choice for part A, one answer choice for part B, and one answer choice for part C.

Question 2:
A: Which of the following expressions will calculate the number of ways the three lead male roles could be cast?
B: Evaluate the permutation from part A.
Select one answer choice for part A, and one answer choice for part B.
A: 22P19
B: ≈1.12×1021
B: 9240
A: 3P22
A: 22P3
B: ≈1.87×1020
The permutation illustrates that if no one has been cast yet, the different ways that are there to cast Jean Valjean from the 22 men is 22.
How to compute the value?The ways to cast Jean will be:
= 22!/(22 - 1)!
= 22!/21!
= 22
When Jean Valjean has already been cast, the different ways that are there to cast Inspector Javert from the remaining men will be:
= 21!/(21 - 1)!
= 21!/20!
= 21
When Jean Valjean and Inspector Javert have already been cast, the different ways that are there to cast Marius from the remaining men will be:
= 20!/(20 - 1)!
= 20!/19!
= 20

Are the expressions –0.5(3x 5) and –1.5x 2.5 equivalent? explain why or why not.
Answer:
not equivalent; signs don't match
Step-by-step explanation:
Apparently, you want to compare the expressions ...
-0.5(3x +5)-1.5x +2.5Distributive propertyThe distributive property allows you to eliminate parentheses by multiplying each term inside parentheses by the factor outside.
ApplicationWhen we do that to the first expression, we get ...
-0.5(3x +5) = (-0.5)(3x) +(-0.5)(5) = -1.5x -2.5
Note that the signs of the terms inside parentheses are the same, and the signs of the terms after removing parentheses are the same. (Both terms have their signs changed by the negative factor multiplying the parentheses.)
The expanded expression -1.5x -2.5 is not equivalent to -1.5x +2.5, which has terms of different signs.

(a) Find the expected value (to the company) per policy sold.

Using the expected value of a discrete distribution, the values are given as follows:
a) $250.
b) $2,500,000.
What is the mean of a discrete distribution?The expected value of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.
The distribution of the company's earnings is given as follows:
P(X = -4400) = 0.02.P(X = -9400) = 0.01.P(X = -29400) = 0.005.P(X = 600) = 0.965.Considering that the policy sells for $600, for example, a $5000 claim is a loss of $5000 - $600 = $4,400 for the company, which explains the above distribution.
Item a:
The expected value for a policy sold is given by:
E(X) = 600(0.965) - 4400(0.02) -9400(0.01) - 29400(0.005) = 250.

Step-by-step explanation:
The number of 4 letter words can be constructed from ABCDE would be 5^4 = 625
The number of 4 letter words can be constructed using BCD would be 3^4 = 81
So the number of words that use at least one vowel would be 5^4 - 3^4 = 625-81 = 544
