There are 2.5 cm in an inch. Express 100 inches in mks units? 10 m 0.25 m 25 m 2.5 m The Correct Answer and Explanation is: To convert 100 inches into MKS (meter-kilogram-second) units, we need to follow these steps: So, the correct answer is 2.5 meters. Explanation: The problem requires us to convert

2 + root 5 by minus 254 squared minus 2 minus 5 + 2 + 5 whole square The Correct Answer and Explanation is: Let’s break down the given expression step by step: The expression is: 2+5(−254)2−(2−5+2+5)2\frac{2 + \sqrt{5}}{(-254)^2} – (2 – 5 + 2 + 5)^2(−254)22+5​​−(2−5+2+5)2 Step 1: Simplify the numerator in the first

The atmospheric pressure is 700 mm Hg. What is the pressure in inches of Hg? (760 mm Hg = 29.92 in Hg) 26.7 in Hg 29.3 in Hg 15.3 in Hg 13.5 in Hg 27.6 in Hg The Correct Answer and Explanation is: To convert atmospheric pressure from mm Hg to inches of Hg, we

Draw 2,3-dimethylpentane in its most and least stable conformation using Newman Projections: Use C2 and C3 as your front and back carbons in the projection. Be sure to label which is the most and which is the least stable confirmation; Indicate which type(s) of strain are present in each (and where in each): The Correct

Convert: a. 10 ft lbf/lbm to J/kg b. 500 °R to K c. 1.987 Btu/lb mol °R to cal/g mol K d. 100 BTU/h ft² °F to kW/m² °C e. 0.002 Kg/(m s) to lbm/(ft s) The Correct Answer and Explanation is: Here’s how we can convert each of these units step by step: a)

what is 6.3 repeating as a fraction The Correct Answer and Explanation is: To express the repeating decimal 6.3 repeating as a fraction, we need to use algebra to solve for the value. Step 1: Represent the decimal as a variable Let xxx represent the repeating decimal:x=6.33333…x = 6.33333\ldotsx=6.33333… Here, the digit “3” repeats indefinitely.

What is 0.63 repeating expressed as a fraction in simplest form? The Correct Answer and Explanation is: To express 0.63 repeating as a fraction, follow these steps: Step 1: Let x=0.63‾x = 0.\overline{63}x=0.63 This means the decimal is repeating every two digits (63). So, we can set up the equation: x=0.6363636363…x = 0.6363636363\ldotsx=0.6363636363… Step 2:

The Correct Answer and Explanation is: The correct answer is the fourth number line shown in the image. To determine the correct number line, we must first solve the inequality (2/3)x – 5 > 3. The objective is to isolate the variable x. The solution to the inequality is x > 12. This means that

Ashfaq is asked to explain the difference between a hypothesis, theory, and scientific law, which are terms used when discussing experiments, research, and scientific methodology. He knows that each term has a distinct meaning, and the terms are not interchangeable. Match the descriptive phrases to the correct term. A hypothesis may still be useful even
