Solve the equation for both -1 and 1 first.

50(1/2)^-1 = 100

50(1/2)^1 = 25

Now subtract the two answers and divide by 2 ( -1 to 1 is 2)

75/2 = 37.5

Because the answer got smaller from -1 to 1, the change would be negative.

The rate of change would be -37.5

pecent means parts ou fo 100
x%=x/100

Which of the following expressions is equivalent to the radical expression?

qwelly [4]

The correct answer is B) $m^{2/3}n^{5/3}$ .

The denominator of the exponent is the root we are taking. The numerator is the exponent of the radicand. This means 3 will be the denominator, since it is a cubed root, and 2 will be the numerator of m while 5 will be the numerator of n.

Prime numbers are not divisible by any number but themselves or 1.

A) 115 is divisible by 5, so it is not prime

B) 273 is divisible by 3 (you get 91), so it is not prime

C) 317 is prime! only divisible by itself or 1

D) 414 is divisible by 2, so it is not prime. Even numbers are never prime because they are divisible by 2!

And an 11 ounce bag of rice noodles makes 10 servings at that rate find how many ounces of noodles I needed for 19 servings to t

nikdorinn [45]

Answer:

20.9 ounces of rice noodles are required to make 19 servings.

Step-by-step explanation:

We are given the following in the question:

11 ounce bag = 10 servings

Ration of ounces of rice noodles to servings is:

$\dfrac{\text{Weight of rice noodles}}{\text{Serivings}} = \dfrac{11}{10} = 1.1$

We have to find ounces of noodles are needed for 19 servings.

Thus, we can write:

$\dfrac{\text{Weight of rice noodles}}{19} = 1.1\\\\\Rightarrow \text{Weight of rice noodles} = 1.1\times 19\\\Rightarrow \text{Weight of rice noodles} =20.9\text{ ounces}$

Thus, 20.9 ounces of rice noodles are required to make 19 servings.
