The correct answer is: $8.125$ Explanation We divide 65 by 8: Steps: $$65 \div 8 = 8\text{ remainder }1$$ $$8\times 8 = 64$$ $$65-64 = 1$$ Convert the remainder to a decimal: $$1\div 8 = 0.125$$ Add to the whole part: $$8 + 0.125 = 8.125$$ Therefore, 65 divided by 8 is $8.125$ (or $8$ with a remainder of $1$).

Round off 278.785 to the nearest hundredth

The correct answer is: $278.79$ Explanation We are rounding $278.785$ to the nearest hundredth (two decimal places). The hundredths digit is $8$ and the digit to its right (the thousandths) is $5$, so we round the hundredths up by $1$. Steps: Identify digits: tenths $=7$, hundredths $=8$, thousandths $=5$. Rounding rule: if the digit right of the hundredth is $5$ or greater, increase the hundredth by $1$. Apply the rule: $278.785$ → hundredths $8$ becomes $9$ → $$278.785\approx278.79$$ Therefore, $278.785$ rounded to the nearest hundredth is $278.79$.

Input Output 8 2 11 5 15 9 17 ? What is the output if the input is 17? A. 11 B. 14 C. 15 D. 16

The correct answer is A. Explanation Each output equals the input minus 6: $output = input - 6$. For 8: $8 - 6 = 2$ For 11: $11 - 6 = 5$ For 15: $15 - 6 = 9$ So for 17: $17 - 6 = 11$, which is option A.

The correct answer is: $67\text{ in}$ Explanation You convert feet to inches (1 ft = 12 in), then add the extra inches. Steps: Convert feet to inches: $$5\times12=60\text{ in}$$ Add the remaining inches: $$60+7=67\text{ in}$$ Therefore, 5 ft 7 in = $67\text{ in}$.

How Many Seconds in Hour

The correct answer is: $3600$ Explanation One minute has $60$ seconds and one hour has $60$ minutes, so multiply the two to get seconds per hour. Steps: One minute: $1\text{ min}=60\text{ s}$ One hour: $1\text{ h}=60\text{ min}$ Multiply: $$60\text{ s/min}\times60\text{ min/h}=3600\text{ s/h}$$ Therefore, there are 3600 seconds in one hour.

4 thousands 7 hundreds 47

The correct answer is: $4,747$ Explanation We convert each place value to its numeric value and add them: 4 thousands = 4000, 7 hundreds = 700, and 47 is 47. Steps: First step: $4\text{ thousands}=4\times1000=4000$ Second step: $7\text{ hundreds}=7\times100=700$ Third step: $47=47$ Final step: $4000+700+47=4747$ Therefore, "4 thousands 7 hundreds 47" equals $4,747$.
