How do you tell if a number is divisible by 8

1 answer:

5 0

If the number is a multiple of 8, it is divisible by 8.
The multiples of 8 are: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88... etc.

If a number is very big, let's say 176, see if you can deduct 80 from it. For this, 176 can be deducted by 80 twice, which will give you a remainder of 16 (I.e. 176 - 80 - 80 = 16". If this remainder (i.e. 16) is divisible by 8, 176 is divisible by 8.

For even larger numbers, try deducting 800, or even 8000.

Let's say you're trying to see if 2464 is divisible by 8. In this case, 2464 can be deducted by 800 thrice (I.e. 2464 - 800 - 800 - 800 = 64), and 64 is its remainder. Since 64 is divisible by 8, 2464 is divisible by 8.

Hope this helps! :)

A factory produces some batteries daily. 7/8 of the batteries are packaged immediately. 2/3 of the

frozen [14]

Answer:

$\frac{1}{24}$

Step-by-step explanation:

Let the total number of batteries produced daily be represented by x.

7/8 of the batteries are packaged immediately.

So the total number of packaged batteries = $\frac{7x}{8}$

Remaining batteries = $x-\frac{7x}{8}$

= $\frac{x}{8}$

Two third of the remaining batteries are sent to charity.

So the total number of batteries sent to charity= $\frac{2}{3} * \frac{x}{8}$

= $\frac{x}{12}$

Remaining batteries are faulty.

So the total number of faulty batteries = $\frac{x}{8} - \frac{x}{12}$

= $\frac{3x - 2x}{24}$

= $\frac{x}{24}$

So the faction of batteries which are faulty =

= $\frac{x}{24} \div x$

= $\frac{1}{24}$

This is Grade 9 Mathematics so I kinda stuck here so, if somebody can help me Please sin30⁰+csc60⁰

mamaluj [8]

$\huge\mathrm{Answer࿐}$

$\sin(30) + \csc(60)$

$\dfrac{1}{2} + \dfrac{2}{ \sqrt{3} }$

$\dfrac{ \sqrt{3 } + 4 }{2 \sqrt{3} }$

To remove √3 from denominator, we multiply both numerator as well as denominator with √3

$\dfrac{ \sqrt{3 } + 4 }{2 \sqrt{3} } \times \dfrac{ \sqrt{3} }{ \sqrt{3} }$

$\dfrac{3 + 4 \sqrt{3} }{6}$

Answer:

3 1/3 miles The answer is D

Step-by-step explanation:

The first trip to school is 5/6 miles. Multiply that by 2 because she also walked home and you get 10/6. Then add the distance she she walked to the library- which simplifies to 5/6 and you get 20/6. That simplifies to 3 1/3.

Suppose that taxis in New York are driven an average of 60,000 miles per year with a standard deviation of 11,000 miles. Assume

Gre4nikov [31]

<span>Let n be the number of taxis in NY. The average distance travelled is 60,000 miles, therefore the middle 95% will have the same average as the population, the reason being the mileage is symmetrically distributed about the mean Therefore the total number of miles in one year for the middle 95% is 60,000 * 0.95 * n
</span><span>The range of miles driven by the middle 95% can be found from the empirical rule that says: For a normal distribution, approximately 95% of the data points lie within the range plus and minus 2 standard deviations of the population mean. In this case the range is (60,000-22,000) to (60,000 + 22,000)</span>
