Answer: 2 liters for $3.80 because the unit rate is $1.90

Unit rate of (1 /5 barrel) / (1/2hour) is equals to (2/5) barrels /hour.

"Unit rate is defined as the representation of the ratio of the two different units with value of the denominator equals to 1."

According to the question,

Given,

[tex]\frac{\frac{1}{5} barrel}{\frac{1}{2} hour}[/tex]

⇒ (1 / 2) hour = ( 1/ 5) barrel

⇒ 1 hour = ( 2 / 5) barrel

⇒( 2 / 5) barrel per 1 hour

Therefore,

Unit  rate of given value is rewritten as

[tex]\frac{2}{5}[/tex] barrel / hour

Hence, Option(B) is the correct answer.

Answer:

Step-by-step explanation:

With x = 1, we can substitute the value 'x' as the exponent. Answers are below.

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

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)

Step-by-step explanation:

The last number of a linear equation will always be the y intercept. In word problems, the y intercept is where the initial start is. In this case, it would be 500, the tank starts off with 500 liters. Since the "-9x" is negative(decreasing), that means that by every minute(x) 9 liters are decreasing.

The value after one year will be $535.

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.

Step-by-step explanation:

We are given that  

6.75 and 6.732  

We have to compare two given decimal numbers.  

First we convert like decimal number  

In 6.75 there are two digits after decimal point.  

In 6.732 , there are three digits after decimal point  

Therefore, we put zero in 6.75 to convert like decimal number

Now, we get  

6.750  

Unit place of both decimal numbers are same and tenth place of both decimal number are same.  

Now, hundredth place of 6.750 is 5 and hundredth place of 6.732 is 3
