You work at the local dairy. The dairy produces 512 gallons of milk on average a day. How many cups of milk does the dairy produ
Oksana_A [137]

Answer:

The number of cups of milk does dairy produce is 8192

Step-by-step explanation:

Given as :

The average per day production of milk = 512 gallons

We know that  the measure of 1 gallons is equivalent to 16 cups

So, The conversion of gallons in cups as

<u>1 gallons = 16 cups</u>

Now ,

∵ 1 gallons = 16 cups

∴ 512 gallons = 16 × 512 cups

I.e 512 gallons = 8192 cups

Hence The number of cups of milk does dairy produce is 8192   Answer

Factor x^4-5x^2+4 show your work
ch4aika [34]

Answer:

(x+2)(x-2)(x+1)(x-1)

Step-by-step explanation:

STEP 1: Rewrite x^{4} as (x^2)^2.

(x^2)^2-5x^2+4

STEP 2: Let u=x^{2}. Substitute u for all occurrences of x^{2}.

u^2-5u+4

STEP 3: Factor u^2-5u+4 using the AC method.

(u-4)(u-1)

STEP 4: Replace all occurrences of u with x^2.

(x^{2} -4)(x^{2} -1)

STEP 5: Rewrite 4 as 2^{2}.

(x^{2}-2^{2})(x^{2}-1)

STEP 6: Since both terms are perfect squares, factor using the difference of squares formula,a^2-b^2=(a+b)(a-b) where a=x and b=2.

(x+2)(x-2)(x^{2}-1)

STEP 7: Rewrite 1 as 1^{2}.

(x+2)(x-2)(x^2-1^2)

STEP 8: Factor.

(x+2)(x-2)(x+1)(x-1)

Simplify algebraic expression 9+5n-3-5n
nadezda [96]

Answer:

6

Step-by-step explanation:

You have to add like terms. So the 5n and -5n would cancel each other out (because 5-5=0) and 9-3=6.

Solve for w<br> s=w-10e<br> -------<br> m
polet [3.4K]
First, multiply both sides by m:
s*m = w - 10e
Then add 10e to both sides to isolate w:
s*m + 10e = w
or
w = s*m + 10e

Question 1: Find the equation of the line through point (5,4) and perpendicular to y=−43x−2. Use a forward slash (i.e. "/") for
Mariulka [41]

Answer:

Question 1: y = 3/4x + 1/4.

Question 2: y = 6/5x + 7/5.

Step-by-step explanation:

Question 1: A line perpendicular to another line would have a slope that is the negative reciprocal of the other line. If the slope of the first line is -4/3, the slope of a line perpendicular to the first would have a slope of 3/4.

Since the line goes through (5, 4), we can just put the points into the equation, y = 3/4x + b.

4 = 3/4(5) + b

b + 15/4 = 4

b = 16/4 - 15/4

b = 1/4

So, the equation of the line is y = 3/4x + 1/4.

Question 2: 5x + 6y = -6

6y = -5x - 6

y = -5/6x - 1

As stated before, a line perpendicular to another will have a slope that is the negative reciprocal of the other. So, the slope of the other line is 6/5.

The line goes through (-2, -1), so we can put the points into the equation, y = 6/5x + b.

-1 = 6/5(-2) + b

b - 12/5 = -5/5

b = -5/5 + 12/5

b = 7/5

So, the equation of the line is y = 6/5x + 7/5.

Hope this helps!
