A car averages 32 mpg. Gas costs $1. 97 per gallon. How much would it cost to pay for the gas if this car made a trip of 866 mil
eimsori [14]

The cost to pay for the gas if this car made a trip of 866 miles cost is $53.31.

A car averages 32 mpg and gas costs $1.97 per gallon.

By unitary method for 866 miles, average would be,

= 866/32

= 27.0625 miles per gallon

and the cost to pay for the gas if this car made a trip of 866 miles would be,

= 27.0625 × $1.97

= $53.31

Therefore, the cost to pay for the gas if this car made a trip of 866 miles cost is $53.31.

Anyone know these two questions??
gogolik [260]

1):  Answer  =====>  Letter Choice, (B),  The rate in which you walked home, The slope is the same, as the Rate of Change, In Distance Divided by the Change in Time  =====>    d    =     4   -1/15t(4) / 1/15t

 

2):   The Equation:  d     =       -1/15t     +     4

The more the Number of Minutes:  Larger the Negative Quantity;  ====>   -1/15t

The Larger the Negative Quantity in Equation:  D value is Smaller:

Therefore your Answer ===>  The Distance from home (d), Decreased with Minute Walked (t)  ====>  So, Letter Choice,  (C)



2):   Towards your home, The slope is Negative, and the Distance (y - value), Decreases, as the Time  (x- Values),  Increases. Notice the Slope is Negative, Because, you are getting closer to home.






Hope that helps!!!!                                           : )

zhenek [66]
“A” : because a proportional relationship has to go through the origin. “A” has a y-intercept of 8 so it’s not considered proportional.
