Answer:

15 pencils

Step-by-step explanation:

(You can write ratios with x because you are multiplying all parts of the ratio by the same amount in order for it to be the same ratio)

The ratio of pencils to pen is 3x:5x

If there are 10 more pens than pencils, and the ratio is 3x:5x, we see that the difference between 3x and 5x is 2x

So now we know that 2x = 10

so x = 5

Since x = 5, we plug in the number to 3x:5x which would be 3(5):5(5) which would be 15:25

So there are 15 pencils.

I hope this helped, let me know if you have any questions

Answer:

<em>D.1767.1 in³</em>

Step-by-step explanation:

<em>volume of a sphere=4/3πr³</em>

<em>where r=radius of the sphere</em>

<em>Given diemeter= 15in</em>

<em>so radius=15/2=7.5in</em>

<em>volume=4/3×π×(7.5)³</em>

<em>=4/3×22/7×(7.5)³</em>

<em>=1767.1in³</em>

<em>hope it helps...</em>

Naddika [18.5K]

Here is you're answer:

In order to get you're answer you need to find the common denominator then add.

  • \frac{1}{6} + \frac{3}{8}
  • Find the common denominator:
  • CD = 48
  • = \frac{26}{48}
  • Simplify:
  • \frac{26}{48} \div 2 = \frac{13}{24}
  • = \frac{13}{24}

Therefore you're answer is option D "13/24."

Hope this helps!
