12. d > -4

13. m > 4

14. x < 3

15. d < ^-15/7

16. m > -6

==========================================================

Explanation:

14 & 2/25 = 14 + 2/25 = 14 + 0.08 = 14.08

The mixed number 14 & 2/25 is the same as the decimal 14.08

The goal is to end up with 14.08 pounds of coffee.

Let x be the starting amount of coffee, in pounds. It will decrease to 14.08 pounds.

We start with x and decrease by 12%. So we are computing this expression

x - 12% of x = 1x - 0.12x = (1-0.12)x = 0.88x = 88% of x

We can see that if we lose 12%, we keep the remaining 88%

The 0.88x is the final weight.

Set 0.88x equal to the goal of 14.08 and solve for x.

0.88x = 14.08

x = (14.08)/(0.88)

x = 16

You'll need to start off with 16 pounds of coffee if you want to end up with 14.08 pounds after losing that 12%

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

Check:

12% of 16 = 0.12*16 = 1.92

16 - 1.92 = 14.08

The answer is confirmed.

You need to order approximately 4.15 pounds of fresh coffee to get 14 2/25 pounds of roasted coffee after accounting for the 12% weight loss during roasting.

To find out how much fresh coffee you need to order to get 14 2/25 lb of roasted coffee, you'll need to account for the 12% weight loss during the roasting process.

Let's assume "x" represents the amount of fresh coffee (in pounds) you need to order. When this fresh coffee is roasted, it will lose 12% of its weight, leaving you with 100% - 12% = 88% of the original weight as roasted coffee.

Now, set up a proportion to find "x":

(88/100) * x = 14 2/25 lb

First, convert the mixed number 14 2/25 to an improper fraction. It becomes (364/25) lb.

Now, solve the equation for "x":

(88/100) * x = 364/25

To eliminate the fraction, you can multiply both sides of the equation by the reciprocal of (88/100), which is (100/88):

x = (364/25) * (100/88)

Now, simplify the expression:

x = 4.15 lb (rounded to two decimal places)

Answer:

can i see the options for the multiple choice ?

Step-by-step explanation:

Hello there!

Linear functions have a continuous pattern in their x and y values.

Let's see the first table.

0, 1, 2, 3

We add 1 every time.

-3, -2, 0, 3

We add 1, add 2, add 3.

That's not a linear function, because it doesn't have a continuous pattern in its y values.

Let's look at the next table.

0, 1, 2, 3

We add 1 every time.

1, 4, 3, 7

We add 3, subtract 1, add 3

That's not a linear function as well.

Now, let's look at the third table:

0, 1, 2, 3

We still add 1.

2, 0, -2, -4

We subtract 2 every time.

So this is a linear function. Hope this helps!

Answer:

hi

Step-by-step explanation:

Let x = the length of the sides of the base and h = the height:

Volume = (area of base)(height)

V = x2h

2048 = x2h

2048/x2 = h

Surface Area = area of base + 4(area of vertical side)

SA = x2 + 4xh

Eliminate the h by using 2048/x2 = h:

SA = x2 + 4x(2048/x2)

SA = x2 + 8192 x-1

Take the derivative of SA wrt x, set it to zero, solve for x.  Plug that value of x into the surface area equation to find the minimum surface area.
