A taxi company charges passengers $1.75 for a ride, no matter how long the ride is, and an additional $0.40 for each mile travel

ed. The rule c = 0.40m + 1.75 describes the relationship between the number of miles m and the total cost of the ride c. a. What is the charge for a 1-mile ride? b. What is the charge for a 2.7-mile ride?

a) m = 1

 c = 0.4(1) +1.75 = 0.4 + 1.75 = 2.15

b)

m = 2.7

c = 0.4(2.7) + 1.75 = 1.08 +1.75 = 2.83

Scott used 1 3 tablespoons of salt to make 1 4 liters of beans. If Scott's recipe is for 1 liter of beans, how much salt will he
olasank [31]

Answer:

B) 4 tablespoons of salt

Step-by-step explanation:

Here is the correct question: Scott used 1/3 tablespoons of salt to make 1/4 liters of beans. If Scott's recipe is for 1 liter of beans, how much salt will he need to make triple the recipe?

Given is the ratio of salt and beans to make recipe for 1 liter of beans.

Ratio given for 1 liters of beans; \frac{salt}{beans} = \frac{\frac{1}{3} }{\frac{1}{4} }.

Now, simplifying the ratio

\frac{\frac{1}{3} }{\frac{1}{4} }= \frac{1}{3} \times \frac{4}{1}

∴ Ratio for salt and bean in a recipe for 1 liter of beans is \frac{4}{3}.

Next, finding the proportion of salt to make triple the recipe.

Triple the recipe means 3 times of 1 liter of beans, which is 3 liters of beans.

∴ The proportion of salt in 3 liter beans= \frac{4\ tablespoon\ salt}{3\ tablespoon\ beans} \times 3\ lts\ of\ beans

Hence, 4 tablespoon of salt is required to make 3 liters of beans or triple the recipe.

Option A. is correct for the given condition.

Lets solve it through steps of range and functions,

First of all, Solve the equation:
f(x) = |x|+5
= > x = -5 (1)

= > x = 5 (2)

So these would be the ranges of X in between 5 and -5.

Hence option A. R{f(x)eR  [f(x) < 5} is correct.

Answer: f(x) = 4  if -1 ≤x ≤ 1

f(x) = x - 1 if 3≤ x ≤ 5

Step-by-step explanation:

if -1 ≤x ≤ 1

We can see that in this range the function is constant, f(x) = 4

if 3≤ x ≤ 5

In this region we can see a linear relationship, with the points (3, 2) and (5, 4)

as the extremes, we can find the slope of this linear equation as:

s = (4 - 2)/(5 - 3) = 2/2 = 1

So our equation is

f(x) = 1*x + b

to find the value of b we can evaluate our function in the first point, we know that when x = 3, y = 2, so we have:

2 = 1*3 + b

b = 2- 3 = -1

then f(x) = 1*x  - 1

Then we have:

f(x) = 4  if -1 ≤x ≤ 1

f(x) = x - 1 if 3≤ x ≤ 5
