A factory uses 220,000 gallons of water to produce
2 tons of steel. How many gallons of water are
needed to produce 1 pound of steel?


A 55 gallons
B 110 gallon
C 110,000 gallon
D 440,000 gallon

Answers

Answer 1
2 tons = 4,000 pounds

So, 220,000 gallons of water is used to produce 4,000 pounds of steel.

4,000 pounds = 220,000 gallons

Divide both sides by 4,000 to get:

1 pound = 55 gallons.

So the correct answer is A.

Evaluate the function at x = -3.

Answers

Answer:

hold on

Step-by-step explanation:

Given the function, p(x) = 4x^3 + 2x^2 - 3x + 2:

We can substitute the value of x = -3 as input into the given function:

p(-3) = 4x^3 + 2x^2 - 3x + 2

p(-3) = 4(-3)^3 + 2(-3)^2 - 3(-3) + 2

p(-3) = 4(-27) + 2(9) - 3(-3) + 2

p(-3) = -108+ 18 - (-9) + 2

p(-3) = -90 + 9 + 2

p(-3) = -81 + 2

p(-3) = -79

Solve the inequality for x
12x>9(2x-3)-15

Answers

Step-by-step explanation:

12x > 9(2x - 3) - 15

12x > 18x - 27 - 15

12x > 18x - 42

42 > 6x

7 > x

so, this is true for all values < 7

so, x is in (-infinity, 7)

both ends but included - therefore the round brackets.

Can someone tell me what the answers are to each question. I did some of them but I would like to see if they’re also right.

Answers

1) r(x) = 18x
2) c(x) = 4.50x + 30,000 because it costs them 4.50 for each slipper made plus the annual cost of 30,000. It doesn’t ask for how much they earned, just the costs.
3) p(x) = 18x - 4.50x - 30,000, they gain 18$ per slippers sold, lost 4.50 per slippers sold, and lost 30,000 from the annual fee. It can be simplified down to p(x) = 13.5x - 30000
4) loss of 3000$, substitute 2000 for x for the equation and solve
5) 172,500, same as the last question but substitute 15,000
6) p(x) = 19x - 5.25 - 30,000

Answers

Answer:

Step-by-step explanation:

For number 8, to start,:

[tex]\frac{x}{4}[/tex] - 1 = 1

the first step is to add 1 to both sides of the equation; then, simplify.

[tex]\frac{x}{4}[/tex] - 1 = 1

   +1    +1

----------------

next, the -1 and +1 will cancel.

[tex]\frac{x}{4}[/tex] = 2

the last step is to multiply both sides of the equation by 4.

4 · [tex]\frac{x}{4}[/tex] = 2 · 4

simplify; the 4s cancel out on the left side.

x = 8

**************************************************

For number 9, :

9 = 6 + [tex]\frac{x}{7}[/tex]

like in number 8, the first step is to subtract 6 from both sides of the equation; also, a helpful tip you can use is move the 9 to the right side; speaking personally, it often helps make things visually easier to work out. you would then rewrite the equation like: 6 + [tex]\frac{x}{7}[/tex] = 9

6 + [tex]\frac{x}{7}[/tex] = 9

now, we'd subtract 6 from both sides.

6 + [tex]\frac{x}{7}[/tex] = 9

-6         -6

-----------------

next, the 6 and -6 will cancel.

[tex]\frac{x}{7}[/tex] = 3

the last step is to multiply both sides of the equation by 7.

7 · [tex]\frac{x}{7}[/tex] = 3 · 7

simplify; the 7s cancel out on the left side.

First, notice that (a + 1/a)2 = 42 = 16. But also, (a + 1/a)2 = a2 + 2a(1/a) + 1/a2 = a2 + 2 + 1/a2 = a2 + 1/a2 + 2

So a2 + 1/a2 + 2 = 16, so a2 + 1/a2 = 14.

Now, do that again...

(a2 + 1/a2)2 = 142 = 196, but also (a2 + 1/a2)2 = a4 + 2(a2)(1/a2) + 1/a4 = a4 + 2 + 1/a4 = a4 + 1/a4 + 2

So a4 + 1/a4 + 2 = 196, so a4 + 1/a4 = 194

You can see the pattern... E.g., a8 + 1/a8 = 1942 - 2, etc.
