Answer:
3 19/30 hours
Step-by-step explanation:
The given fractions will have 30 as a common denominator.
12/30 + 1 5/30 + 2 2/30 = (1 +2) +(12 +5 +2)/30 = 3 19/30 . . . hours

The answer is B
Answer: total number of teaspoons of spices in the dish =3.25 teaspoons
Step-by-step explanation:
Step 1
Listing the spices and their quantities , we have
Salt = 1/2 teaspoon
Orégano =1 1/4 teaspoon =5/4 teaspoons
Basil = 3/4 teaspoon
Pepper= in half as much pepper as salt -- This means that the quantity of pepper should be 50% more in quantity than salt
Therefore quantity of pepper = 50% x 1/2 = 0.5 x 0.5= 0.25
0.25 + 1/2 = 0.25 + 0.5 = 0.75 = 3/4 teaspoon of pepper.
Step 2
Adding the amount of spices we have
1/2 + 5/4+ 3/4+ 3/4 = 2+ 5+3+ 3/4 = 13/4 = 3 1/4 teaspoons of spices = 3.25 teaspoons of spices .
Since, A 3-mi cab ride costs $7.30 and a 8-mi cab ride costs $15.30.
In the information given above, we can consider these as the coordinate points on the axes.
Let (c, d) be the coordinates , where 'c' represents the total cost and 'd' represents the distance traveled.
Cost is on the 'y' axis and distance is on the 'x' axis.
Now, let the first point on the coordinate axes be (3, 7.30) and the other point is given by (8, 15.30).
For the given points say and , equation of line is given by:
where m(slope) is given by .
The equation of line for the given points is:
So, c = 1.6d+2.5 is the required linear equation that models a relationship between cost c and distance d.
