ok so if you have 3 and 1/4 pizza and want to subtract 3/4 out of it,and get 3x more slices then you had from a friend after sub
Brilliant_brown [7]

Answer:

You have 2 and 1/2 pizzas and your friend has 5/6 of a pizza.

Step-by-step explanation:

You have 3 1/4 pizzas. If you get rid of 3/4 of a pizza, you will end up with 2 2/4 pizzas.

To make it easier, you can just change the values into improper fractions: 3 1/4 = 13/4

13/4 - 3/4 = 10/4

10/4 = 2 2/4 pizzas

(2 2/4 = 2 1/2)

Anyways! You now have 2 and a half pizzas. You have 3 times the amount of pizza that your friend has. In other words, your friend has 1/3 the amount of pizza that you have. You can solve for this in two ways, whichever way you solve it is up to you.

  1. You can solve this problem by dividing the amount of food you have by 3: \frac{2\frac{1}{2} }{3} which equals 0.8333... (the 3 is repeating). But you can just keep your final answer in fraction form if you want to: \frac{2.5}{3} = \frac{5}{6}
  2. You can solve this problem by multiplying 1/3 to the amount of food you have: \frac{1}{3} * 2 \frac{2}{4}\\=\frac{10}{12}\\ =\frac{5}{6}

You have 2 and 1/2 pizzas and your friend has 5/6 of a pizza.

MArishka [77]

Answer:

218.7 lb.

Step-by-step explanation:

We have been given that the  weight of male american between the ages 18 to 25 is normally distributed, with mean of 162.7 lb and a standard deviation of 28 lb.

One definition of obesity states that a person is obese if the z-score of his or her weight is greater than 2.

We will use z-score formula to solve our given problem.

z=\frac{x-\mu}{\sigma}, where,

z=\text{ z-score},

x=\text{ Random sample-score},

\mu=\text{ Mean},

\sigma=\text{ Standard deviation}.

Upon substituting our given values in z-score formula we will get,

2=\frac{x-162.7}{28}

Now let us solve for x.

Upon multiplying both sides of our equation by 28 we will get,

2*28=\frac{x-162.7}{28}*28

56=x-162.7

Let us add 162.7 to both sides of our equation.

56+162.7=x-162.7+162.7

218.7=x

Therefore, the obesity threshold weight for a young adult American male is 218.7 pounds.
