Cole worked 20 hours and earned $500. How many hours must Cole work in order to earn $700?
Answers
Hi! I'm Carriyana!! Glad to help you today! :)
Cole needs to work 28 hrs!!
My steps:
First I did 500/20 and got 25
Then I did 700/25
And ended up with 28
So the answer should be...
~28 hrs!~Answer:
28 hours
Step-by-step explanation:
To calculate how many hours Cole must work to earn $700, we must first calculate how much he makes per hour.
This can be done by taking the total amount he earned and dividing by the number of hours:
$500 / 20 hours = $25 an hour
Since we now know how much he makes an hour, we can determine how many hours it takes to earn $700 by using a similar equation to the one above:
Total Money / Total Hours = $ an hour
$700 / Total Hours = $25 an hour
It can be represented algebraically as:
700 / x = 25
Then, solve for x:
(700 / x) * x = (25) * x
700 = 25x
(700) / 25 = (25x) / 25
28 = x
28 hours

For the third week of April, Patricia Thomas worked 53 hours. Patricia earns $11.90 an hour. Her employer pays overtime for all hours worked in excess of 40
hours per week and pays 1.5 times the hourly rate for overtime hours.
Calculate the following for the third week of April (round your responses to the nearest cent if necessary):
1. Regular pay amount
2. Overtime pay
3. Gross pay
Answers
Given statement solution is :- For the third week of April, Patricia's:
Regular pay amount is $476.
Overtime pay is $231.45.
Gross pay is $707.45.
To calculate Patricia's pay for the third week of April, we'll need to determine her regular pay, overtime pay, and gross pay.
Regular Pay:
Patricia worked 53 hours, but only 40 hours are considered regular hours. Therefore, the regular pay is calculated as follows:
Regular Pay = Regular Hours x Hourly Rate
Regular Pay = 40 hours x $11.90/hour
Regular Pay = $476
Overtime Pay:
Since Patricia worked 53 hours in total and 40 of those are regular hours, the remaining 13 hours are considered overtime hours. Overtime pay is calculated by multiplying the overtime hours by 1.5 times the hourly rate.
Overtime Pay = Overtime Hours x (Hourly Rate x 1.5)
Overtime Pay = 13 hours x ($11.90/hour x 1.5)
Overtime Pay = 13 hours x $17.85/hour
Overtime Pay = $231.45
Gross Pay:
Gross Pay is the sum of Regular Pay and Overtime Pay.
Gross Pay = Regular Pay + Overtime Pay
Gross Pay = $476 + $231.45
Gross Pay = $707.45
Therefore, for the third week of April, Patricia's:
Regular pay amount is $476.
Overtime pay is $231.45.
Gross pay is $707.45.

b. P(x<11) = 0.7143
Step-by-step explanation:
The question is incomplete
In October, Apple introduced a much smaller variant of the Apple iPad, known as the iPad Mini. Weighing less than 11 ounces, it was about 50% lighter than the standard iPad. Battery tests for the iPad Mini showed a mean life of hours (The Wall Street Journal, October 31, 2012). Assume that battery life of the iPad Mini is uniformly distributed between 8.5 and 12 hours.
a. Give a mathematical expression for the probability density function of battery life.
b. What is the probability that the battery life for an iPad Mini will be 11 hours or less (to 4 decimals).
a. We model the battery life as random variable with an uniform distribution with parameters a (min. value)=8.5 hours and b (max. value)=12 hours.
The probability that the battery life takes any value between 8.5 and 12 is constant. Also, the probability that takes any value outside the interval (8.5, 12) is 0.
We can express that as:
\(f(x)={\begin{cases}{\dfrac {1}{12-8.5}}=\dfrac{1}{3.5}&\mathrm {for} \ 8.5\leq x\leq 12,\\[8pt]0&\mathrm {for} \ x<8.5\ \mathrm {or} \ x>12\end{cases}}\)
The last is the probability density function for the battery life.
b. We can calculate P(x<11) using the cumulative density function or integrating the density function between x=0 (or x=a=8.5) and x=11.
\(P(x<11)=\int\limits^{11}_{8.5} \dfrac{1}{3.5} \, dx=\dfrac{1}{3.5}(x_2-x_1)=\dfrac{1}{3.5}(11-8.5)=\dfrac{2.5}{3.5}= 0.7143\)

DIVIDE 3000 RUPEES AMONG TEENA AND BEENA SO THE THEY GET 40% AND 60% RESPECTIVELY
Answers
Answer:
To divide 3000 rupees between Teena and Beena so that they get 40% and 60% respectively, we need to follow these steps:
Step 1: Find the total percentage that Teena and Beena will receive together:
40% + 60% = 100%
This means that Teena and Beena will receive 100% of the total amount, which is 3000 rupees.
Step 2: Calculate the amount that Beena will receive:
60% of 3000 rupees = 0.6 x 3000 = 1800 rupees
Step 3: Calculate the amount that Teena will receive:
40% of 3000 rupees = 0.4 x 3000 = 1200 rupees
Therefore, Beena will receive 1800 rupees, while Teena will receive 1200 rupees

Is 28,45,53 a Pythagorean Triple
Answers
Answer:
28,45,53 is a Pythagorean Triple
Step-by-step explanation:
To determine whether 28, 45, and 53 form a Pythagorean triple, we need to check whether they satisfy the Pythagorean theorem, which states that for any right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
So, we need to check whether:
28^2 + 45^2 = 53^2
Evaluating the left-hand side of the equation, we get:
784 + 2025 = 2809
And evaluating the right-hand side of the equation, we get:
2809 = 2809
Since both sides are equal, we can conclude that 28, 45, and 53 form a Pythagorean triple, because they satisfy the Pythagorean theorem. Therefore, 28^2 + 45^2 = 53^2 is a true statement, and we can say that the lengths 28, 45, and 53 can form the sides of a right triangle.

Answer:
Slope = - 1/3
Step-by-step explanation:
Choose the point on the right and move upwards. How many times did you move upwards until you were at the same level as the point on the left? You moved once, which means your rise is 1.
Now from the point where you are at now, move right or left depending on where the point is. In this case, it's on the left which means our run will be negative. Now move left until you reach that point on the left. How many times did you move left? You moved three times, which means your run is 3.
Rise/Run = -1/3
Slope = Rise/Run
Slope: - 1/3

Answers
Respuesta:
2/9
Explicación paso a paso:
Dado que :
tarjeta numerada = 1 - 15
Probabilidad de obtener un número no menor o igual a 5
Número de cartas no menor o igual a 5:
Tarjeta no ≤ 5 = (6,7,8,9,10,11,12,13,14,15) = 10
Probabilidad = resultado requerido / Total de resultados posibles
P (Tarjeta no ≤ 5) = 10/15 = 2/3
Número de cartas menor o igual a 5:
Tarjetas ≤ 5 = 1, 2, 3, 4, 5
P (Tarjeta ≤ 5) = 5/15 = 1/3
P (Tarjeta no ≤ 5) * P (Tarjeta ≤ 5)
2/3 * 1/3 = 2/9
Calcularemos la probabilidad del evento combinado para obtener: P = 0.22
Calculando las probabilidades individuales:La probabilidad de sacar una carta menor o igual a 5 es igual al cociente entre el numero de cartas con un número menor o igual a 5 y el número total de cartas en el mazo.
Tenemos 5 cartas con un número igual o menor a 5 y un total de 15 cartas, así que la probabilidad es:
p = 5/15
La probabilidad de que no le salga una carta menor o igual a 5 es calculada de la misma forma, hay 10 cartas que no son menores o iguales a 5 y un total de 15 cartas, entonces tenemos:
q = 10/15
La probabilidad conjunta es simplemente el producto de esas dos probabilidades, así obtenemos:
P = (10/15)*(5/15) = 10/45 = 0.22

Find the probability that a randomly selected point within the square falls in the red-shaded triangle. 3 3 4 P = [?] 4
Answers
The required probability is 3 √7 / 32.
Given, a square with sides of length 4 units and a red-shaded triangle with sides 3 units, 3 units and 4 units. We need to find the probability that a randomly selected point within the square falls in the red-shaded triangle.To find the probability, we need to divide the area of the red-shaded triangle by the area of the square. So, Area of square = 4 × 4 = 16 square units. Area of triangle = 1/2 × base × height.
Using Pythagorean theorem, the height of the triangle is found as: h = √(4² − 3²) = √7
The area of the triangle is: A = 1/2 × base × height= 1/2 × 3 × √7= 3/2 √7 square units. So, the probability that a randomly selected point within the square falls in the red-shaded triangle is: P = Area of triangle/Area of square= (3/2 √7) / 16= 3 √7 / 32.
