Answer:

V=113.1

Step-by-step explanation V=(4/3)*pi *r^3 r=d/2 here d=6 in so r=3 which is the only variable in the equation , put that value in the equation and you will got the volume

4/9times 1/8 simplified and 2/17 times 8/1 simplified

son4ous [18]

here is an example of how to solve your problem.

4 3/9 - 2 2/9 = ?

• Check for common denominators: They are like fractions with a common denominator of 9. Do nothing.

• Subtract the numerators from each fraction: 3 - 2 = 1

• Write the difference of the numerators above the common denominator: 1/9

• Subtract the whole numbers: 4 - 2 = 2

• Write out the new mixed number: 2 1/9

• Simplify: 1/9 can't be simplified. You are done.

Answer: 4 3/9 - 2 2/9 = 2 1/9

hope it helps;)

If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23

Leto [7]

Given :

All the natural numbers below 1000 that are multiples of 3 or 5 .

To Find :

The sum of all the multiples of 3 or 5 below 1000.

Solution :

Max multiple of 3 is 999 .

Max multiple of 5 id 995 .

So , number of multiple of 3 is :

$999=a+(n-1)d\\\\999=3+3(n-1)\\\\n=333$

Similarly for 5 .

$995=a+(n-1)d\\\\995=5+5(n-1)\\\\n=199$

Now , sum of all multiple of 3 is given by :

$S_3=\dfrac{n}{2}(2a+(n-1)d)\\\\S_3=\dfrac{333\times (2\times 3+332\times 3)}{2}\\\\S_3=166833$

Also , sum of all multiple of 5 is :

$S_5=\dfrac{n}{2}(2a+(n-1)d)\\\\S_5=\dfrac{199\times (2\times 5+198\times 5)}{2}\\\\S_5=99500$

Therefore , total sum :

$T=S_3+S_5\\\\T=166833+99500\\\\T=266333$

Now , there are some common number which we add two times like :

15 , 30 , 60 ......

So , we should subtract the sum of all multiple of 15 from T .

Now , sum of all multiple of 15 is 33165 .

So ,

$T=266333-33165\\\\T=233168$

Therefore , the sum of all the multiples of 3 or 5 below 1000 is 233168 .

Urgent please help..

The answer is 51.3

Explanation:
You’re finding angle Y, so write the SOH CAH TOA. the two sides your are given are the adjacent side to Y and the opposite side so you use tangent. You then get the equation tanY=10/8 Since you’re finding an angle you use inverse tangent so you get y=tan^-1(10/8) and then put that into the calculator!
