The surface area S of a cube is equal to the sum of the areas of the 6 square faces that form the cube. We want to paint the cube and need to know how many square units of paint to purchase. If each face has side length s, then the formula S = 6s2 can be used to find the surface area of the cube. The length of a side is indicated in the cube below( s = x - 5). The surface area of the cube is 1944 units2.
What is the value of x? SHOW and EXPLAIN each of the steps you used to solve
Answer:
23
Step-by-step explanation:
-The length of the cubes side is (x-5) and the total surface area is 1944 sq units.
-We apply the formula for surface area and equate to solve for x:
[tex]A=6s^2\\\\1944=6(x-5)^2\\\\324=(x-5)^2\\\\324=x^2-10x+25[/tex]
#Equate to zero as below:
[tex]324=x^2-10x+25\\\\x^2-10x+25-324=0\\\\x^2-10x-299=0\\\\\# Quadratic \ Formula:\\\\x_{1,2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}\\\\\\=\frac{10\pm\sqrt{(-10)^2-4(1\times-299)}}{2\times1}\\\\x_1=23, \ \ \ x_2=-13[/tex]
length dimensions are always positive.

Piper can run 3 laps in 8 minutes. Walker can run 10 laps in 25 minutes. Sophie can run 1 lap in 3 minutes. Who is the slowest runner?
Answer:
Sophie
Step-by-step explanation:
For each runner, divide their time running by the laps they ran.
Piper: 8÷3≈2.7
Walker: 25÷10=2.5
Sophie: 3÷1=3
Sophie takes the longest time to run one lap, she is the slowest.
Answer:
Sophie is the slowest runner.
Step-by-step explanation:
We are given the various constant of proportionally s.
3:8, 10:25, & 1:3
Simplify each one by finding a least common factor, LCF, for the first side of such, and multiply the number that would be needed to get to such on both sides.
Thus, 30 laps in 80 seconds , 30 laps in 75 seconds , and 30 laps in 90 seconds.
As seen here, 30:90 is lowest, so Sophie is the slowest runner.

Suppose that the probability that a person will die in the next 20 years is
17.5452%. If this person has a life insurance policy that will pay out $25,000
to the beneficiaries of the policy if the person dies in the next 20 years, what
is the premium of the policy? Assume that the administrative costs of the
policy amount to $65.
O A. $4450.50
O B. $4581.30
O C. $25,000
O D. $4523.89
Answer: $4450.50
Step-by-step explanation:
Just guessed and got it right
The premium of the policy will be $4451.3.
What is Insurance?A person or organisation and an insurance company enter into a contract known as insurance whereby the person or organisation pays the insurance company a premium in exchange for financial protection or reimbursement in the case of an unanticipated loss or event. Up to the limitations outlined in the insurance policy, the insurance company promises to pay for any covered losses or damages. Insurance can be used to guard against a range of hazards, such as liability, property damage, death, and injury.
The premium of the policy can be calculated as:
Premium = (Probability of death x Benefit amount) + Administrative costs
So,
Premium = (0.175452 x 25000) + 65
Premium = 4,386.3 + 65
Premium = $4,451.3.

A number cube is rolled three times. What is the probability of rolling a number less than 3 each time?
Answer:
8/27
Step-by-step explanation:
The probability of rolling a number less than 3 three times in a row on a number cube (or die) is 1/27.
Explanation:The subject of this question is probability in mathematics. A number cube, often referred to as a die, has six faces numbered 1 through 6. If we are looking for the probability of rolling a number less than 3, we are looking for the probability of rolling a 1 or a 2. Out of six possibilities, two are successful outcomes (1 and 2), so the probability of rolling a number less than 3 in one roll is 2 out of 6, or 1/3.
However, since the number cube is rolled three times, we have to consider this probability for each roll. In probability, when we want to find the likelihood of multiple events all occurring, we multiply the probabilities of each individual event. Therefore, the probability of rolling a number less than 3 three times in a row is (1/3) * (1/3) * (1/3) = 1/27.

Student council expects $150 students for a dance and spends $10 on food for each student. The council expects the number of students to increase by 8% each year for the next 5 years and wants to reduce the amount of money spent on food by 4% for each student each year.
Use the drop-down menus to choose or create functions to model:
A. The predicted number of students over time, S(t)
B. The predicted amount spent per student over time,A(t)
C. The predicted total expense for food each year over time, E(t)
We developed three functions to model student attendance, per-student expenditure, and total food cost. S(t) = 150 * (1 + 0.08)^t models the number of students, A(t) = 10 * (1 - 0.04)^t models the cost per student, and E(t) = S(t) * A(t) models the total cost.
Explanation:We are asked to model the predicted number of students, the amount spent per student and the total expense for food per year over time.
A. The function S(t) = 150 * (1 + 0.08)^t represents the predicted number of students over time.
'S' stands for the number of students.'t' stands for the time in years.B. The function A(t) = 10 * (1 - 0.04)^t represents the predicted amount spent per student over time.
'A' stands for the amount spent per student.C. The function E(t) = S(t) * A(t), represents the total predicted expense for food each year over time.
'E' stands for the total expense.So, 'S(t)' represents the increase of students, 'A(t)' represents the decrease in the amount spent per student, and 'E(t)' the total expenditure of food each year.

John and Tyrone each go for a morning jog before work. John's jogging
pace is represented by the equation y=5x, where y is the number of
miles he jogs and x is the number of hours he jogs. Tyrone's pace is
given by the graph. Choose the statement that correctly compares their
unit rates.
The question asks to compare the unit rates of two joggers, John and Tyrone. John's unit rate is 5 miles per hour, as indicated by the equation y=5x. Without Tyrone's graph data, a direct comparison cannot be made.
Explanation:The subject of the question involves comparing unit rates of two joggers, which requires an understanding of linear equations and graph interpretations in mathematics. Based on the given information, John's jogging pace is defined by the linear equation y=5x, where y is the number of miles he jogs and x is the number of hours he jogs. This equation suggests that John's unit rate, or his speed, is 5 miles per hour. However, to compare John's unit rate to Tyrone's, we need additional information about the slope of Tyrone's graph, which represents his speed.
Without the specific graph or a defined equation for Tyrone's pace, we can't make a direct comparison. Typically, the unit rate for a jogger is found by taking the slope of the position vs. time graph, which involves dividing the change in position (the rise) by the change in time (the run). If the slope of Tyrone's graph were provided, we could determine his speed and compare it to John's.
Remember, the unit rate is a measure of how much of something occurs per unit of another thing. In this case, it's the speed at which each jogger moves per hour. If additional data from Tyrone's graph were given, we would look for a constant rate of change or identify two points on the graph to calculate the slope (speed) and thus compare the unit rates of the two joggers.

Suppose chocolate costs $17.60 per kilogram. Karega buys 25 grams of chocolate and Samadhi buys 100 grams of chocolate.
How much more did Samadhi pay for her chocolate?
$0.44
$1.32
$2.20
$2.64
Samadhi paid $1.32 more than Karega for her chocolate.
Explanation:The subject of this question is in Mathematics, specifically it involves unit conversion and arithmetic calculations. We know that chocolate costs $17.60 per kilogram. But Karega and Samadhi are buying chocolate in grams which means we need to convert the cost from kilograms to grams. 1 kilogram is equal to 1000 grams. So, cost of chocolate per gram = $17.60/1000 = $0.0176.
Karega is buying 25 grams of chocolate, so the cost = 25 * $0.0176 = $0.44. Samadhi is buying 100 grams of chocolate, so the cost =$0.0176 * 100 = $1.76. To find out how much more Samadhi paid for her chocolate compared to Karega, we subtract Karega's cost from Samadhi's cost which gives $1.76 - $0.44 = $1.32.
