(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?
==========================================================
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)

A bank pays 7% interest on 3-year certificates of deposit. What is the value of a $500 certificate after one year? Give your answer to the nearest cent.
The value after one year will be $535.
What is interest?Interest, in its most simple form, is calculated as a percent of the principal. For example, if you borrowed $100 from a friend and agree to repay it with 5% interest, then the amount of interest you would pay would just be 5% of 100: $100(0.05) = $5.
Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan. For example, a bank will pay you interest when you deposit your money in a high-yield savings account.
given:
amount= $500
interest rate = 7% on 3-year certificates of deposit.
So, after one year the value will be
=500 x 7% + 500
=500 x 0.07 + 500
= 35 + 500
= $535
Hence, the value will be $535.

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?
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

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
