Step by step explanation:

Answer: For 3 Batches, 6 butter & 9 flour
For 5 Batches, 10 butter & 15 flour
Step-by-step explanation:
1 Batch = 2:3
So, whatever we times up by in batches we can do the same to the ingredients.
1 batch = 2:3
multiply 3
3 batches = 6:9
and so on…
For this problem you can create a proportion.
Since 31,100 copies is 7.8% of the total copies spoke up to date you can make this proportion:
31,100. 7.8%
——— =. ———
x. 100%
Now you cross multiply and you will get
7.8x=3,110,000
After this you solve for x by isolating the variable.
7.8x/7.8. 3,110,000/7.8
x=398,717.949
Since the question asks you to round to the nearest whole number which is 7 then the final answer would be 398,718
Answer: There has been 398,718 copies sold to date.
Answer:


Step-by-step explanation:
Area:
π 
π
*Square 2x*
π
*Divide by π*
*Divide by 4*
*Square root*
*Solve*
x ≈ 3.482
Now take the same equation but replace 2x with 3x
π 
Now replace x with 3.482 and solve for area.

Volume:
π
*Insert variables*
π
*Cube 2x*
π
*Multiply
on both sides*
π
*Divide by π*
*Divide by 8*
*Cube root*
*Solve*
x ≈ 2.208
Now take the same equation but replace 2x with 3x
π
Now replace x with 2.208 and solve for volume.

Answer:
The most t-shirts that he can buy is 3
Step-by-step explanation:
He has $50 and needs to have $10 for lunch. So take away the money for lunch and that leaves you with $40. Each t-shirt cost $12 so $40 divided by $12 is 3.333333333. But you can't buy a part of a t-shirt you the most t-shirt you can buy is 3
