we are given
![\frac{\sqrt[3]{7}\sqrt{7}}{\sqrt[6]{7^5}}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%5Csqrt%5B3%5D%7B7%7D%5Csqrt%7B7%7D%7D%7B%5Csqrt%5B6%5D%7B7%5E5%7D%7D%20%20%20%20%20)
we can write it in terms of exponents
Firstly , we will simplify numerator
now, we can add exponents
we can cancel it
and we get
............Answer
Answer:
C. 31
Step-by-step explanation:
3000 there are 3-4 errors
If we first divide 24,000 by 3,000, will get 8
then since there a error for each 3,000 books, we do 8 x 4 = 32 and 8 x 3 = 24
32 (8 x 4) the max amount of printing errors
24 (8 x 3) the minimum amount of printing errors
So we should expect 24-32 printing errors
Only answer between the numbers is c. 31
Answer:
see explanation
Step-by-step explanation:
(1)
given
4x² = 81 ( divide both sides by 4 )
x² = 
( take the square root of both sides )
x = ± 
= ± 
---------------------------------------------------------------------
(2)
subtract 7 from both sides
(4x - 3)² = 32 ( take the square root of both sides )
4x - 3 = ± 
= ± 4
Add 3 to both sides
4x = 3 ± 4 ( divide both sides by 4 )
x = 
±
The circumference would also be doubled. The formula to find circumference is 2π r; since radius is just the diameter divided by two, if you double it the radius also doubles. All in all, this doubles the circumference. For example, if the diameter was 10, the radius would be 5. Circumference for this circle would equal 31.4. Now, if you were to double the diameter to equal 20, thus making the radius 10, the circumference would be 62.8.
Mary should charge $8.0 per ounce.
From the question the herbal tea is a blend of 2 kinds of mint:
75% spearmint- $2.25
25% peppermint-$ 2.75.
The cost of producing one ounce is:
75% spearmint- $2.25 + 25% peppermint-$ 2.75. =$5
The cost of the tea if it is to be sold 1.6 times will be calculated thus;
$5×1.6= $8.0
To get the new cost of the mint tea blend, the old cost is thus, multiplied by 1.6. This gives us the new cost of the mint tea blend.
Therefore cost per ounce will be $8.0
