Answer:
We have been given that a car can travel 476 miles on 14 gallons of gas and we are asked to write an equation relating the distance d to the number of gallons g.
We can set an equation as distance traveled is directly proportional to number of gallons used in travelling that distance.
Now we will find out K(number of miles traveled in one gallon of gas) by substituting our given values in this equation.
Therefore, we can see that car travels 34 miles in one gallon of gas.
Now we can use this information to find out how many gallons of gas does this car need to travel 578 miles.
Let us divide number of miles to be traveled by number of miles traveled in one gallon of gas to find out number of gallons of gas needed.
Therefore, car need 17 gallons of gas to travel 578 miles.

Answer:
Then, the object will take 29.11 min to travel
Step-by-step explanation:
When an object is moving at a steady speed, we can calculate the time it would take to travel a given distance using the following formula:
(equation 1)
In this particular, both the given speed and distance are mixed fractions so we'll first convert them into improper fractions to operate more easily:
So, now we can calculate the time using the equation 1:
And, if we want the result in minutes:
Then, the object will take 29.11 min to travel
Answer:
You could use one quarter and two dimes... that will equal $0.45

Answer:
<em>A.</em><em> There were 400 larvae at 0 degree Celsius.</em>
Step-by-step explanation:
Here,
x = the temperature of water in °C
y = the number of insect larvae in the water
The graph is a graph of quadratic function as it is a parabola and it opens downward, so it has a negative leading coefficient i.e coefficient of x² is negative.
At y intercept, the line or curve passes through y axis. At y intercept the value of x is zero, because on y axis the value of x is 0.
As the y intercept in this case is (0, 400), so at y intercept value of x is 0 and y is 400.
Therefore, at y intercept or at 0°C there were 400 larvae.
