What is -20 Celsius in Fahrenheit?

The correct answer is: $-4\text{ °F}$ Explanation To convert Celsius to Fahrenheit use the formula $F = C \times \frac{9}{5} + 32$. Steps: Formula: $$F = C \times \frac{9}{5} + 32$$ Substitute $C = -20$: $$F = -20 \times \frac{9}{5} + 32$$ Compute: $$F = -36 + 32 = -4\text{ °F}$$ Therefore, $-20^\circ\text{C}$ equals $-4\text{ °F}$.

what is 5 feet, 2 inches in meters

The correct answer is: $1.5748\text{ m}$ Explanation You convert feet and inches to meters by first converting everything to inches, then to centimeters (using $1\text{ in}=2.54\text{ cm}$), and finally to meters. Steps: Convert feet to inches: $$5\text{ ft}=5\times12=60\text{ in}$$ Add the extra inches: $$60\text{ in}+2\text{ in}=62\text{ in}$$ Convert inches to centimeters: $$62\times2.54=157.48\text{ cm}$$ Convert centimeters to meters: $$157.48\text{ cm}=\frac{157.48}{100}\text{ m}=1.5748\text{ m}$$ Rounded answers: about $1.575\text{ m}$ (to three decimal places) or $1.57\text{ m}$ (to two decimal places).

How much is 37.6 Celsius in Fahrenheit fever?

The correct answer is: $99.7^\circ\text{F}$ Explanation 37.6°C converted to Fahrenheit is about 99.7°F. This is mildly elevated but below the common clinical fever cutoff (usually defined as $38^\circ\text{C}$ / $100.4^\circ\text{F}$). Some sources call temperatures around $37.5\text{–}38^\circ\text{C}$ (about $99.5\text{–}100.4^\circ\text{F}$) a low‑grade fever. Steps: Formula: $$F=\frac{9}{5}C+32$$ Substitute: $$F=\frac{9}{5}\times37.6+32$$ Compute: $$F=67.68+32=99.68^\circ\text{F}\approx99.7^\circ\text{F}$$ If you or someone else has symptoms or is in a high‑risk group (infant, elderly, immunocompromised), contact a healthcare provider even for low‑grade elevations.

How to convert 98° Fahrenheit to celsius

The correct answer is: $36.666\ldots^\circ\text{C}$ (approximately $36.7^\circ\text{C}$) Explanation Use the Fahrenheit-to-Celsius conversion formula: $$C=(F-32)\times\frac{5}{9}$$ Steps: Substitute $F=98$: $$C=(98-32)\times\frac{5}{9}$$ Compute the difference: $$C=66\times\frac{5}{9}$$ Multiply and simplify: $$C=\frac{330}{9}=\frac{110}{3}=36.666\ldots$$ Therefore, $98^\circ\text{F}$ equals $36.666\ldots^\circ\text{C}$, which is commonly rounded to $36.7^\circ\text{C}$. Quick check: Convert back with $F=C\times\frac{9}{5}+32$: $36.666\ldots\times\frac{9}{5}+32=98^\circ\text{F}$.

Human body temperature is 37°C. Convert it in Fahrenheit.

The correct answer is: $98.6^\circ\text{F}$ Explanation We use the Celsius-to-Fahrenheit conversion formula: Fahrenheit equals Celsius times 9/5 plus 32. Plugging in $37^\circ\text{C}$ gives the familiar normal body temperature in degrees Fahrenheit. Steps: Formula: $$F = C \times \frac{9}{5} + 32$$ Substitute $C=37$: $$F = 37 \times \frac{9}{5} + 32$$ Calculate: $$F = 37 \times 1.8 + 32 = 66.6 + 32 = 98.6^\circ\text{F}$$ Therefore, $37^\circ\text{C}$ equals $98.6^\circ\text{F}$.

How many inches are in 13 cm?

Question

How many inches are in 13 cm?

Q: How many inches are in 13 cm?

The correct answer is: $\dfrac{650}{127}\text{ in} \approx 5.1181\text{ in}$ Explanation Convert centimeters to inches using $1\text{ in} = 2.54\text{ cm}$. Divide 13 cm by 2.54 cm per inch to get inches. Steps: First step: $$1\text{ in} = 2.54\text{ cm}$$ Second step: $$x = \frac{13\text{ cm}}{2.54\text{ cm/in}}$$ Final step: $$x = \frac{13}{2.54}\text{ in} = \frac{650}{127}\text{ in} \approx 5.1181\text{ in}$$ Therefore, 13 cm is about $5.1181\text{ in}$ (approximately $5.12\text{ in}$ when rounded to three significant figures).

Answer

100% (3 rated)

The correct answer is: $\dfrac{650}{127}\text{ in} \approx 5.1181\text{ in}$

Explanation

Convert centimeters to inches using $1\text{ in} = 2.54\text{ cm}$. Divide 13 cm by 2.54 cm per inch to get inches.

Steps:

First step: $$1\text{ in} = 2.54\text{ cm}$$
Second step: $$x = \frac{13\text{ cm}}{2.54\text{ cm/in}}$$
Final step: $$x = \frac{13}{2.54}\text{ in} = \frac{650}{127}\text{ in} \approx 5.1181\text{ in}$$

Therefore, 13 cm is about $5.1181\text{ in}$ (approximately $5.12\text{ in}$ when rounded to three significant figures).
