That is false because you have to subtract the exponents not divide
If i had to take a guess i would say they would turn at 65.9 feet per second and since there are 12 inches in a foot. It would be about 5.49 inches per minute
Answer:
6n + 12 =40
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Direct Variation takes the form
Inverse Variation takes the form ![A=k(\frac{1}{B})](https://tex.z-dn.net/?f=A%3Dk%28%5Cfrac%7B1%7D%7BB%7D%29)
- Where A and B are the 2 variables associated and k is the proportionality constant.
<em>Since </em><em>number of dolls [N] </em><em>varies </em><em>directly </em><em>with </em><em>advertising budget [A],</em><em> in our equation, </em><em>A should go in the numerator</em><em> and since </em><em>number of dolls [N] </em><em>varies </em><em>inversely</em><em> with </em><em>price of dolls [P]</em><em>, </em><em>P should go in the denominator.</em>
Thus we can write our equation as:
![N=k(\frac{A}{P})](https://tex.z-dn.net/?f=N%3Dk%28%5Cfrac%7BA%7D%7BP%7D%29)
Solving this equation for k given the information "The company sold 5200 dolls when $26,000 was spent on advertising and the price of a doll was set at $30":
![N=k(\frac{A}{P})\\5200=k(\frac{26,000}{30})\\5200=k(866.67)\\k=\frac{5200}{866.67}=5.99](https://tex.z-dn.net/?f=N%3Dk%28%5Cfrac%7BA%7D%7BP%7D%29%5C%5C5200%3Dk%28%5Cfrac%7B26%2C000%7D%7B30%7D%29%5C%5C5200%3Dk%28866.67%29%5C%5Ck%3D%5Cfrac%7B5200%7D%7B866.67%7D%3D5.99)
Rounding
to ![k=6](https://tex.z-dn.net/?f=k%3D6)
Now, given that we want to find the number of dolls [N] when
and
, we have:
dolls
Answer choice D is correct.
