A self-serve frozen yogurt store sells servings up to 12 ounces. It charges $0.50 per ounce for a serving between 0 and 8 ounces, and $4 for any serving greater than 8 ounces and up to 12 ounces.


Build the function that models the relationship between the price p(w) and of the weight w of a serving of yogurt.

Answers

Answer:

p(w) - - - - - - p = 0.5w ; for 0 < w ≤ 8

p(w) - - - - - - p = 4 ; for w < 8 and w ≤ 12

Step-by-step explanation:

Price, p of weight of a toughurt serving :

p(w) - - - - - - p = 0.5w ; for 0 < w ≤ 8

p(w) - - - - - - p = 4 ; for w < 8 and w ≤ 12

The function that models the relationship is:

p(w) = 0.50w  for 0  <  w  ≤ 8

p(w) = 4w   for  8 < w ≤ 12

The self-serve frozen yoghurt store charges:

$0.50 per serving for a serving between 0 and 8 ounces

$4 per serving for any serving greater than 8 ounces and up to 12 ounces.

Let the weight of servings be represented by w

Let the price as a function of the weight be p(w)

For a charge of $0.50 per serving:

p(w)  =  0.50w,  where   0  <  w  ≤ 8

For a charge of $4 per serving:

p(w) = 4w, where 8 < w ≤ 12

Therefore, the function that models the relationship is:

p(w) = 0.50w  for 0  <  w  ≤ 8

p(w) = 4w   for  8 < w ≤ 12

hallar la medida del angulo "y"​

Answers

Answer: y = 11.25

Step-by-step explanation:

Mi espanol es terrible :l

Todos los angulos terminaran acompletando 90° grados

Entonces hagamos una ecuacion

3y + 4y + y = 90

8y = 90

Divide por 8

y = 11.25

Esta parte no es necesaria

Para ver si es verdad hagamos el math

3(11.25) = 33.75

4(11.25) = 45

y = 11.25

33.75 + 45 + 11.25 = 90

Answer:

-7 > -10

Step-by-step explanation:

We just have to compare these two numbers. When you're comparing two negative numbers, the smaller number is the bigger one. Ex. -3 is bigger than -6, so we can say that -3 > -6 (-3 is greater than -6). This means that -7 is larger than -10, which allows you to say that -7 > -10.
