Answer:
t = (m / g) * p
Step-by-step explanation:
Since we are given a variable for every part of the equation that we need we can go ahead and create the following equation where t equals the total cost
t = (m / g) * p
In this equation, we need to first divide the total number of miles by the number of miles that the car gets per gallon. This would give us the total number of gallons that the car would use during the entire trip. We then multiply the number of gallons by the price per gallon to get the final cost of the entire trip.

Answer: Option #4: the 0.2 could be changed to 2.
Explanation: 
The table is designed to make the concept of percentages more understandable. The table first allocates the total amount of 70 in terms of its "fifths," or 20% parts. Then it expresses these parts in the last row of the table, showing that 20% of 70 is 14 and all the five parts sum up to 70 again. 
Now, Mikel is supposed to express 40% of the amount. So she writes (incorrectly): 0.2 * 14. This statement needs to be changed to 2 * 14 (two times 14 = 28), to correspond to 2 times 20%, or 40%  of 70. 
This is reflected in the last (fourth) option "The 0.2 in the expression could be changed to 2." 
Option #3 is incorrect because changing 14 to 70, will result in an incorrect number (2.8). 
Options 1 and 2 are similarly incorrect (as can be easily verified)
 
        
                    
             
        
        
        
Answer:
5.2 in
Step-by-step explanation:
An equilateral triangle is a triangle with 3 equal sides 
Divide the equilateral triangle into two congruent triangles and use Pythagoras theorem to find the height
The Pythagoras theorem : a² + b² = c²
where a =  height
b = base = 6 in / 2 = 3 in  
c =  hypotenuse = 6 in 
6² = 3² + h² 
h = 36 - 9 = 27
√27 = 5.196 inch
to the nearest tenth = 5.2 in
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
