If 12x=12−−√11, what value of x makes this equation true?

Solnce55 [7]

Answer:

$\dfrac{1}{11}$

Step-by-step explanation:

Apply exponent rule:

$\sqrt[n]{a} =a^{\frac{1}{n}}$

$\implies \sqrt[11]{12}=12^{\frac{1}{11}}$

$\implies 12^x=12^{\frac{1}{11}}$

$\implies x = \dfrac{1}{11}$

John Johnson is forty-seven. He is purchasing twenty-year endowment insurance, with a face value of $20,000. What is his annual

Alenkinab [10]

The answer is Letter D - 939.80.

You can refer to the attachment for the rate. Since he is forty-seven years old, use that age to find his rate under a twenty-year endowment insurance. In this case, the rate is 46.99. Multiply that rate to 20 since he purchased a 20-year endowment insurance with a face value of $20,000. (20,000/1,000 = 20)

46.99 x 20 = 939.80

Let's say that you go out for dinner. The meal and the service are excellent. You want to leave a really good tip for the waiter

Oduvanchick [21]

First, to estimate we can round 53.82 up to 55.00. Then you can look at it like this: when you divide 100 by 20 you get 5, so 20% is one fifth of 100. Therefore, we want to find one fifth of $55. To do this, you multiply 55*1/5. When you multiply the numerators by each other and the denominators by each other, you get 55/5. When you divide the numerator and denominator by 5, you get 11/1 or $11.

Hope this helps

Allushta [10]

Answer:

Inequality that represents the amount paid by neighbors of Dani will be

x ≤ 8 + (4 + 16)

Step-by-step explanation:

Let the neighbors of Dani paid her to take care of their bird = $x

Danny spent on an afternoon snack = $4

She paid the amount for a new book = $16

Now the amount left with her is at least $8.

Therefore, inequality which represents the amount paid by her neighbor will be

x - 4 - 16 ≤ 8

x ≤ 8 + (4 + 16)
