12 ch 5 warm up: people's weights (java) (1) prompt the user to enter five numbers, being five people's weights. store the numbers in an array of doubles. output the array's numbers on one line, each number followed by one space. (2 pts) ex: enter weight 1: 236.0 enter weight 2: 89.5 enter weight 3: 142.0 enter weight 4:
Final answer:
The code provided guides the user through entering five weights using a Scanner object, stores them in a double array, and then prints them all on one line separated by spaces.
Explanation:
To address the question of prompting the user to enter five people's weights and storing them in an array of doubles in Java, we need to provide a short piece of code executing this task.
The code will look something like this:
import java.util.Scanner;
class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
double[] weights = new double[5];
for(int i = 0; i < weights.length; i++) {
System.out.println("Enter weight " + (i+1) + ": ");
weights[i] = scanner.nextDouble();
}
System.out.println("The entered weights are:");
for(double weight : weights) {
System.out.print(weight + " ");
}
}
}
This code initializes a Scanner to take user input, creates an array of doubles to store the weights, and uses a for loop to iterate over the array, prompting the user to enter a weight for each element. It then prints out each weight followed by a space.
Will give brainliest!

Roberto Anaya and his wife plan to rent a condominium for $725 per month. They pay a $125 monthly fee for all of the maintenance work. Their annual expenses are insurance $468, lost interest, $129; and utility bills, $3,000. What are their average monthly expenses to the nearest cent?
Answer:
The average monthly expenses is $ 1,149.75
Step-by-step explanation:
Given,
The monthly rent of the condominium = $ 725,
Also, monthly fee for maintenance work = $ 125,
And, Their annual expenses are insurance $468, lost interest, $129; and utility bills, $3,000,
⇒ The total annual expenses in insurance, lost interest and utility bill = $ 468 + $ 129 + $ 3,000
= $ 3597,
⇒ The monthly expenses in insurance, lost interest and utility bills = [tex]\frac{3597}{12}[/tex]
= $ 299.75,
Hence, the average monthly expenses = monthly rent of the condominium + monthly fee for maintenance work + monthly expenses in insurance, lost interest and utility bills
= $ 725 + $ 125 + $ 299.75
= $ 1,149.75

How much time does it take light to travel from the moon to the earth, a distance of 384000?
V = speed of light = 3 x 108 m/s
d = distance = 384000 x 103 m = 3.84 x 108 m
time taken = t = d/V = 3.84 x 108 /(3 x 108 ) = 1.28 sec

A wedding dress is on sale for $225.00,which is 25% off of the original price. What was the original price. how do you solve this?
Answer:
$300
Step-by-step explanation:
Write an equation for the the sale price in terms of the original price. Then solve for the original price.
sale price = (original price) - (percent off) × (original price)
Factoring out the (original price), we have ...
sale price = (original price) × (1 - percent off)
We can find the original price by dividing this equation by (1 - percent off).
(sale price)/(1 -percent off) = original price
Putting in the numbers, we get ...
$225/(1 -25%) = original price
$225/(1 - 25/100) = $225/(1 -0.25) = $225/0.75 = original price = $300

In 10 minutes a heart can beat 700 times. At what rate can a heart beat?
Heart will beat 140 times in 2 minutes.
Heart beats at a rate of 70 beats per minute.
(How it's done down below)
In 0 minutes heart beats 700 times
hence in 1 minute it will beat 700/10=70 times
and heart will beat 140 times in 140/70=2 minutes
Heartbeats at a rate of 70 beats per minute.
Explanation:hence in 1 minute it will beat 700 ÷ 10=70 times

Howard pays $327 for one dozen collector's edition baseball cards. About how much does he pay for each baseball card?
A student solved the equation 6s – 10 = 2 + 3s + s and got s = –4. His work shown below is his check for this problem. Which statement best applies to the work shown? A. His check does not work, thus s = –4. B. The work in his check is all correct, thus s = –34. C. The work in his check is all correct, thus s = –4. D. His check does not work, thus
The student's check does not work, thus s = -4. Therefore, the correct statement is A.
Let's evaluate the student's check for the equation 6s - 10 = 2 + 3s + s when s = -4.
Substitute s = -4 into the equation:
6(-4) - 10 = 2 + 3(-4) + (-4)
-24 - 10 = 2 - 12 - 4
-34 = -14
Since [tex]\(-34 \neq -14\)[/tex], the result obtained by the student's check is incorrect.
Therefore, the statement that best applies to the work shown is:
A. His check does not work, thus s = -4.
Jamar is factoring 90x-15. Find his mistake and correct it
Answer: 15(6x - 1)
Step-by-step explanation: Jamar had a great start, by figuring out the factors of both 90 and 15; of which he picked 15.
What he got wrong was failing to do same to the value 15 exactly what he did to 90x.
To put it right, here is how to go about it:
90x - 15
Factor of both 90 and 15 is 15
Therefore:
15 (6x - 1)
This is correct. You can as well expand the result to check.
The correct factorization will be: 15(6x - 1)
Given,
90x-15
Here,
Jamar had a great start, by figuring out the factors of both 90 and 15; of which he picked 15.
What he got wrong was failing to do same to the value 15 exactly what he did to 90x.
To make it correct:
90x - 15
Factor of both 90 and 15 is 15
Therefore:
15 (6x - 1)
Hence the correct factorization is achieved .

Write two ways to group and add 4+2+5.
Answer:
We can use the associative property of addition to group the numbers for addition.
Step-by-step explanation:
We are given the following information in the question:
We have to add [tex]4 + 2 + 5[/tex] in two different ways.
Associative property of addition
The associative property states that you can add regardless of how the numbers are grouped. By grouped we mean how we use parenthesis.[tex](a+b)+c = a+(b+c)[/tex]Working:
[tex]4 + 2 + 5[/tex]
[tex](4+2)+5 = 4+(2+5)\\6 + 5 = 4 + 7\\13 =13[/tex]
The associative property allows for different groupings of numbers when adding without affecting the sum, such as (4 + 2) + 5 and 4 + (2 + 5), both resulting in 11.
Explanation:In mathematics, especially when dealing with arithmetic operations like addition, we have the flexibility to group numbers in different ways due to the associative property of addition. This property tells us that the way in which numbers are grouped does not affect the sum. Here's how you can group and add the numbers 4, 2, and 5 in two different ways:
Way #1: Group (4 + 2) + 5 = 6 + 5 = 11Way #2: Group 4 + (2 + 5) = 4 + 7 = 11Both methods give us the same result, which is 11, demonstrating the associative property in action.
