The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

To find the Celsius temperature when the Fahrenheit temperature is 90 degrees, the given formula is: F=95C+32F = \\frac{9}{5}C + 32F=59\u200bC+32<\/p>\n\n\n\n

Substitute 90 for FFF: 90=95C+3290 = \\frac{9}{5}C + 3290=59\u200bC+32<\/p>\n\n\n\n

Subtract 32 from both sides: 90\u221232=95C90 – 32 = \\frac{9}{5}C90\u221232=59\u200bC 58=95C58 = \\frac{9}{5}C58=59\u200bC<\/p>\n\n\n\n

Multiply both sides by 59\\frac{5}{9}95\u200b: C=59\u00d758C = \\frac{5}{9} \\times 58C=95\u200b\u00d758 C=2909C = \\frac{290}{9}C=9290\u200b C\u224832.222\u2026C \\approx 32.222\\ldotsC\u224832.222\u2026<\/p>\n\n\n\n

Rounded to the nearest tenth, the result is: C\u224832.2\u2009degrees CelsiusC \\approx 32.2 \\, \\text{degrees Celsius}C\u224832.2degrees Celsius<\/p>\n\n\n\n

Correct answer: C) 32.2 degrees Celsius<\/strong><\/p>\n\n\n\n

Explanation:<\/strong><\/p>\n\n\n\n

Converting between Fahrenheit and Celsius uses a linear relationship based on the freezing and boiling points of water. In the Fahrenheit system, water freezes at 32\u00b0F and boils at 212\u00b0F, while in the Celsius system, water freezes at 0\u00b0C and boils at 100\u00b0C. The given formula, F=95C+32F = \\frac{9}{5}C + 32F=59\u200bC+32, rearranges these fixed points into a mathematical expression.<\/p>\n\n\n\n

The problem involves finding the original Celsius value that, when placed into the equation, gives 90\u00b0F. By isolating the Celsius variable using inverse operations\u2014first subtracting 32, then multiplying by the reciprocal of 95\\frac{9}{5}59\u200b\u2014the formula is effectively inverted.<\/p>\n\n\n\n

Once this value is calculated, the decimal is approximated to the nearest tenth. Decimal rounding is based on the digit in the hundredths place; if that digit is 5 or higher, the tenths place increases by one. In this case, 32.222 rounds to 32.2.<\/p>\n\n\n\n

Answer option C matches this calculated value and is therefore correct.<\/p>\n\n\n\n
