How many integers between 10000 and 99999, inclusive, are divisible by 3 or<br> 5 or 7?
Yuki888 [10]

Answer: Hence, there are approximately 48884 integers are divisible by 3 or 5 or 7.

Step-by-step explanation:

Since we have given that

Integers between 10000 and 99999 = 99999-10000+1=90000

n( divisible by 3) = \dfrac{90000}{3}=30000

n( divisible by 5) = \dfrac{90000}{5}=18000

n( divisible by 7) = \dfrac{90000}{7}=12857.14

n( divisible by 3 and 5) = n(3∩5)=\dfrac{90000}{15}=6000

n( divisible by 5 and 7) = n(5∩7) = \dfrac{90000}{35}=2571.42

n( divisible by 3 and 7) = n(3∩7) = \dfrac{90000}{21}=4285.71

n( divisible by 3,5 and 7) = n(3∩5∩7) = \dfrac{90000}{105}=857.14

As we know the formula,

n(3∪5∪7)=n(3)+n(5)+n(7)-n(3∩5)-n(5∩7)-n(3∩7)+n(3∩5∩7)

=30000+18000+12857.14-6000-2571.42-4258.71+857.14\\\\=48884.15

Hence, there are approximately 48884 integers are divisible by 3 or 5 or 7.

Do decimals have opposites? explain
dybincka [34]
<span>Presumably, the opposite of decimals are fractions because by dividing the two numbers you get the decimal value of the fractional form of the number. Refer to the example below.

How do you write 39/100 into a decimal form is by simply dividing 39 to 100. </span>
<span>Hence, </span>
1. 39 / 100 = 0.39 -> Hence this is the decimal form.

<span>0.39 is the decimal form of the given value. </span>
<span>Other examples can include: </span>
<span><span>1. </span> 100 / 1000 = 0.1</span> <span><span>
2. </span> 45 / 10 = 4.5</span><span>
