The Cost C (in dollars) of making n bracelets is represented by C=45n+125. How many bracelets are made when the cost is $845?

Answers

Answer 1

So we know the cost is $845, which means this is the cost or our C. Lets input this into our equation and solve.

845 = 45n + 125.

Subtract from both sides:

845-125 = 45n + 125-125

720 = 45n

Divide by 45:

720 / 45 = 45n / 45

16 = n

This means that 16 bracelets can be made if the cost is 845.

We can also re-input the information into the equation to be extra sure!

845 = 45 (16) + 125.

845 = 720 + 125.

845 = 845

Yes!

I hope this helps! :)

You have 8 cups of flour. It takes 1 cup of flour to make 24 cookies. The function c(f) = 24f
represents the number of cookies, c, that can be made with f cups of flour.

What domain and range are reasonable for the function?

What do the x-intercept and y-intercept of the graph above represent in this situation?

Answers

Answer:

y = c(f) = 24x so range is 24  domain is 1 the  x intercept and y intercept do not count as an adding value in the equation so in order for  y = c(f) = 24x we need to make x a condition that x=1 and therefore x represents 1

Step-by-step explanation:

Given (1, 24) (8, c(f))  = 24 (8) = 192  = (1, 24) (8, 192)  Then use formula y2-y1/x2- x1 = 192-24/ 8-1 = 168/7 = 24  slope  = 24    equation = (f) = 24x The domain is all values of x that give real numbers as answers, and that is everything except 0, since 1/0 is illegal The range is all the values of y that can be reached from real values of x.

Answer:

y = c(f) = 24x so range is 24  domain is 1 the  x intercept and y intercept do not count as an adding value in the equation so in order for  y = c(f) = 24x we need to make x a condition that x=1 and therefore x represents 1

(BRAINLIEST IF CORRECT ANSWER) When you roast coffee, it loses 12% of its weight. How much fresh coffee do you need to order to get 14 2/25 lb of roasted coffee?

Answers

Answer:  16 pounds

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

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)

Which graph shows the correct solution to the inequality below?

Answers

Answer:

Third Option

Step-by-step explanation:

3x + 18 > 6x - 9

We have to find the value of x for this

Subtract 18 from both sides to leave 3x alone

3x > 6x - 27

Subtract 6x from both sides to be able to find the value of x

-3x > -27

Divide by -3 on both sides

x > 9

The answer would be the third option, since X is anything greater than 9
