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).

Q: 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 $-4\text{ °F}$.

Q: 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).

Q: 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.

Question

Write the name of the period that has the digits 913.

Accepted Answer

The correct answer is: the ones (units) period.

Explanation and steps:

Definition of a period: In place-value notation, digits are grouped into periods of three (starting from the right). The standard period names from right to left are:

Ones (units) period — rightmost three digits
Thousands period — next three digits to the left
Millions period — the next three digits
Billions period — next three, and so on.

How to decide: Find the group of three digits and see where it sits from the right end of the whole number. The rightmost group is the ones period; the second group from the right is the thousands period; the third is the millions period.

Apply to 913:

If the group "913" is the rightmost (end) group of the number (for example: 12,345,913), then 913 is in the ones (units) period.
If the group "913" appears as the second group from the right (for example: 913,245), then 913 would be in the thousands period (meaning 913 thousand).
If it appears as the third group from the right (for example: 1,913,000,000), it would be in the millions period, etc.

Examples:

913 → 913 is the ones period.
913,245 → the left group 913 is the thousands period (913 thousands).
12,345,913 → the rightmost 913 is the ones period (913 units).

Summary:By default, when you see the digits 913 as the rightmost three-digit group, the period name is ones (units). If those three digits occur in other group positions, their period name changes accordingly (thousands, millions, etc.).
