Tracy took a quiz containing 12 items. If she answered 5/6 of them right, how many did she answer correctly?

2 answers:

3 0

To find 5/6 of 12, you do 5/6 multiplied by 12

12*5/6 (first multiply 12 by 5 and leave the answer over 6)
60/6 (simplify)
The final answer is 10

Hope this helps!

That answer is correct but another way to look at it is that since 6 goes evenly into 12, multiply the fraction by 2 so you get 10/ 12 so therefore the answer is 10

Answer:

The first one is 0, the second one is ARN (All real numbers)

Step-by-step explanation:

1. Anything raised to the "zeroth" power is always 1

2. Because 7 is being raised to the zeroth power, the number inside the parentheses becomes 1. Now x can equal anything, 1 times itself will always equal 1, no matter how many times you multiply them.

Anit [1.1K]

Answer:

The correct option is D.

Step-by-step explanation:

Let x denote the years.

The information provided is:

The population of Metro City is 7420.
The population is decreasing by 152 people per year.
The population of Smallville is consistently 1200 less than half of Metro City.

From the provided data derive the equation for the population of Smallville x years after as follows:

$Y = [\frac{1}{2}\cdot (7420-152x)]-1200$

The population of Smallville is 2282 after x years.

Compute the value of x as follows:

$2282= [\frac{1}{2}\cdot (7420-152x)]-1200$

$\frac{7420-152x}{2}=2282+1200\\\\7420-152x=3482\times 2\\\\152x=7420-6964\\\\152x=456\\\\x=3$

Thus, the time it will take for Smallville's population to reach 2282 is 3 years.

The correct option is D.
