In the late 1950s, the most likely setting for computers was a(n) _____. home college classroom specialist government laboratory, e.g., a military lab art gallery
Final answer:
In the late 1950s, computers were mostly found in specialist government laboratories, major corporations, and universities. They were large, expensive mainframes until the introduction of more accessible minicomputers and personal computers in later decades.
Explanation:
In the late 1950s, the most likely setting for computers was a specialist government laboratory, such as a military lab. Early computers like the UNIVAC I and the IBM 701 were large mainframe computers used primarily by government agencies, large businesses, and universities due to their high costs and complex data management systems. It wasn't until the 1970s that minicomputers became somewhat more accessible and later, in the late 1970s and early 1980s, fully assembled personal computers started to appear in businesses and upper-middle-class homes.
a shrug is an example of
Final answer:
A shrug is a "non-verbal communication" gesture indicating uncertainty or indifference, involving the elevation of the scapulae and the trapezius muscles.
Explanation:
A shrug is an example of a non-verbal communication gesture that can convey a variety of messages such as uncertainty, indifference, or lack of knowledge about a particular subject. It is a symbolic action often learned through cultural contexts. Physical movement involves elevating the shoulders, which implicates specific muscles and joints, particularly the trapezius muscles and the scapulae (shoulder blades). When you shrug your shoulders, movements occur at the scapulae, such as elevation and sometimes slight upward rotation, depending upon the intensity of the shrug.

The mass percent of hydrogen in CH₄O is 12.5%.Mass percent is the mass of the element divided by the mass of the compound or solute.
What is the mass percent?Mass percent is the mass of the element divided by the mass of the compound or solute.
Step 1: Calculate the mass of the compound.
mCH₄O = 1 mC + 4 mH + 1 mO = 1 (12.01 amu) + 4 (1.00 amu) + 1 (16.00 amu) = 32.01 amu
Step 2: Calculate the mass of hydrogen in the compound.
mH in mCH₄O = 4 mH = 4 (1.00 amu) = 4.00 amu
Step 3: Calculate the mass percent of hydrogen in the compound.
%H = (mH in mCH₄O / mCH₄O) × 100%
%H = 4.00 amu / 32.01 amu × 100% = 12.5%
The mass percent of hydrogen in CH₄O is 12.5%.
CO2 = 1.580 grams H2O = 0.592 grams Lookup the molar mass of each element in the compound Carbon = 12.0107 Hydrogen = 1.00794 Oxygen = 15.999 Calculate the molar mass of CH4O by adding the total masses of each element used. 12.0107 + 4 * 1.00794 + 15.999 = 32.04146 Now calculate how many moles of CH4O you have by dividing by the molar mass. m = 1.15 g / 32.04146 g/mole = 0.035891 mole Now figure out how many moles of carbon and hydrogen you have. Carbon = 0.035891 moles Hydrogen = 0.035891 moles *
Therefore, The mass percent of hydrogen in CH₄O is 12.5%.

Java is an object-oriented programming language true or false
Java is an object-oriented programming language that utilizes classes and objects to encapsulate data and functions, supporting core concepts like inheritance and polymorphism.
Explanation:True, Java is indeed an object-oriented programming language. It was designed to have as few implementation dependencies as possible, allowing developers to write code that runs anywhere Java is supported. Java is well-known for its portability across platforms, which is achieved through the Java Virtual Machine (JVM). As an object-oriented language, Java uses classes and objects to structure code, encapsulating data and operations on data within these constructs, and supports core concepts such as inheritance, polymorphism, and abstraction.

Write a program that calculates the cost of a phone call. The user enters a positive integer that
indicates the length of the call. The first two minutes of a phone call cost a flat $1.50. Minutes 3 to 10
cost 50 cents each. Each minute after 10 costs 25 cents each.
For example:
How many minutes is the call?
13
A 13 minute call costs 6.25
MY CODE SO FAR:
import java.util.Scanner;
public class Third {
public static void main (String[]args) {
Scanner num = new Scanner (System.in);
System.out.println("Enter number of minutes");
int x = num.nextInt();
I have gotten this far but im not sure what the rest is and how I would create the code for adding minutes. I know it has to do with final but not sure where to start. Thanks.
Here's an example Python code that calculates the cost of a phone call based on the length of the call:
print("How many minutes is the call?")
call_length = int(input())
if call_length <= 2:
cost = 1.50
elif call_length <= 10:
cost = 1.50 + (call_length - 2) * 0.50
cost = 1.50 + 8 * 0.50 + (call_length - 10) * 0.25
print("A", call_length, "minute call costs", round(cost, 2))
In this code, we first ask the user to enter the length of the call in minutes. We then use an if-elif-else statement to calculate the cost of the call based on the length. If the call is 2 minutes or less, the cost is a flat $1.50.
If the call is between 3 and 10 minutes, the cost is $1.50 plus 50 cents per minute after the first 2 minutes.
If the call is longer than 10 minutes, the cost is $1.50 plus $4.00 for the first 8 minutes, plus 25 cents per minute after the first 10 minutes.
We then use the round() function to round the cost to two decimal places and print the result.
Here's an example output for a 13-minute call:
How many minutes is the call?
13
A 13 minute call costs 6.25

In project integration management, project ______ and _______ are intertwined and inseparable activities
Final answer:
In project integration management, project "planning" and "execution" are closely linked and must be managed together. Project managers must cohesively integrate planning, execution, and other processes with the knowledge areas to achieve success.
Explanation:
In project integration management, project planning and execution are intertwined and inseparable activities. These integrations emphasize the importance of a cohesive project environment where planning and executing the project are conducted in such a way that each process influences the other. Project managers must apply their unique skill set, incorporating various processes, including initiation, monitoring and controlling, and closing, aligning with all nine project management knowledge areas to meet the desired goals.
Effective integration management ensures that all elements of the project are properly coordinated, from the scope to the timeline and quality standards, resulting in successful project outcomes. Additionally, aspects like cost, time, communication, human resources, and procurement are vital components that a project manager must also synthesize into a harmonious entirety, often requiring a dynamic and flexible approach to address each project's unique challenges and risks.
