whole milk is 4% butterfat how much skim milk with 0% butterfat should be added to 32 ounces of whole milk to obtain a mixture t

vivado [14]

Answer:

whole milk 4 ---------------- 32 ounces

skim milk 0 ---------------- x ounces

Mixture 2.5 ---------------- 32 + x ounces

4*32+0x =2.5(32 +x)

128+0x= 80+2.5 x

0 x + -2.5 x = 80 - -128

-2.5 x = -48

/ -2.5

x = 19.2

19.2 ounces of 0 % fat skim milk

Please show your work! I have 3 more of these, and I want to be able to do them by myself.

Radda [10]

Answer:

Step-by-step explanation:

We group the number 5:

5(x² + 3x + 2.25)

Now inside the brackets we'll take the square root of the coefficient of the x and the square root of the last number, then remove the square from the x and write it as a sum:

5(x+1.5)²

What's the idea behind this?

Well, remember that when you have something in the form:

(a+b)²

It actually means:

a² + 2ab + b²

In our case a was x, and b was 2.25. For bringing it into the shorter form we have to take the square root of a and b.

Sorry if you don't understand. Tell me if you need help to get the xoncept better.

Find the slope of the line that passes through:<br> (-4,7) and (-6, -4)

Yuri [45]

Answer:

$\frac{11}{2}$ or 5.5

Step-by-step explanation:

In order to find the slope of a line using two points on a graph, you must use

$y_2-y_1/x_2-x_1$

Pluging in the points (-4,7) and (-6, -4) to the formula you will get:

$\frac{-4-7}{-6+4} =\frac{-11}{-2} =5.5$

The equation for the line would be $\frac{11}{2}$ x+29

What is the circumference of the circle if r = 3.5 feet? Use 22 7 for π. A) 5.5 feet B) 11 feet C) 22 feet D) 38.5 feet

Liono4ka [1.6K]

Well, to find the circumference of a circle, we can use the formula
C=2 $\pi$ r.
So just plug in 3.5 into the formula.
C=2 $\pi$ 3.5.
Multiply and we get C=21.99. which is about 22
So our answer would be C. 22 feet.
Hope I helped!
