If 20 oz bottle marked X were to go sale. What would the new price need to be for it to be equal value to the 16 oz bottle ? Wer

zubka84 [21]

Answer:

$1.375 ≈ $1.38

Step-by-step explanation:

First, set up a proportion:

$\frac{16\textrm{ oz}}{\$1.10}}\times\frac{20\textrm{ oz}}{x}$

Then, cross-multiply and solve for x:

$(16)(x)=(20)(1.10)\\16x=22\\x=\frac{22}{16}\\x=1.375$

How do you imagine that you will use measurement in your future career?

tangare [24]

Measurement is used in many careers, but how it will be used depends on what career you want. For example, if I were to become an architect, I will have to use measurement to ensure that a building I'm designing does not collapse due to inconsistencies. On the other hand, if I were to become an animal caretaker, I will have to measure the food each animal receives to ensure that they get a healthy diet. There are many examples, so I can not help with every single one of them.

Express x^2-5x+8 in the form (x-a)^2+b where a and b are integers

zimovet [89]

Answer:

$f(x)=(x-\frac{5}{2})^2+\frac{7}{4}$

Step-by-step explanation:

<u>Complete the square</u>

<u /> $f(x)=x^2-5x+8\\\\f(x)-1.75=x^2-5x+8-1.75\\\\f(x)-1.75=x^2-5x+6.25\\\\f(x)-1.75=(x-2.5)^2\\\\f(x)=(x-2.5)^2+1.75\\\\f(x)=(x-\frac{5}{2})^2+\frac{7}{4}$
