If a frozen yogurt has 75 calories in 2 oz, how many are in 8 oz of yogurt?
irina [24]

Answer:

The answer would be 300 calories

Step-by-step explanation:

To find the amount of calories in 8 ounces we need to make the ounce amount the same. Let x equal the number of calories.

75/2=x

To get to 8 ounces we need to multiply the bottom by 4. and what we do to the bottom we do to the top.

75*4/2*4=x

multiply

300/8=x

There are 300 calories in 8 ounces.

How do i Solve: 3x2−6x−12=0 ?
MrMuchimi

Answer:

1 + root 5, 1 - root 5

Step-by-step explanation:

I assume you mean 3x^2-6x-12=0.

First, note that you can divide both sides by 3. You get:

x^2-2x-4=0

Use the quadratic equation.

x=\frac{2\pm\sqrt{4+16}}{2}=\frac{2\pm2\sqrt{5}}{2}=1\pm\sqrt{5}

Therefore, x=1 + root 5, 1 - root 5

Anna71 [15]
There are numerous important information's already given in the question. Based on those information's the answer to the question can be easily determined.
Number of movies that are drama = 5
Number of comedy movies = 8
Number of adventure movies = 11
Total number of movies that Jazmin has = 5 + 8 + 11
                                                                 = 24
Then
Ratio of adventure movies to the total number of movies = 11:24
This ratio of 11:24 cannot be simplified further. So this is the answer to the given question. I hope the procedure is clear enough for you to understand.
