Consider the NASCAR race, the Indianapolis 500. Its name refers to the total race distance of 500 miles. There are 44 cars are r
lukranit [14]

Answer: $5289.35

Step-by-step explanation:

Since the cars have an average mileage of 6.78 miles per gallon and the race is 500 miles, the number of gallons each car will take will be:

= 500/6.78

= 73.75 gallons

Since they're 44 cars, the total gallons of fuel will be:

= 44 × 73.75

= 3245 gallons

Since the fuel cost is $1.63 per gallon, the total fuel cost, will be:

= $1.63 × 3245

= $5289.35

Analyze is the product of 0.4×1.8 greater than or less than 0.4?please explain to me
AnnZ [28]
Remember that multiplying is how many times you add a number to itself. If you multiply by 3, you add the first number to itself 3 times.

When you multiply a given number by 1, you get the first number (it doesn't change).

When you multiply by a number less than one, say, one half, you'll end up with half of the original number --> a smaller number.

When you multiply a number by more than one, you will get a number bigger than the original because you are adding it to itself more than once. Even if it is a fraction or decimal, if it is greater than 1, then the new product will be larger than the original number.

Hope this helps! :)

A line has a slope of -4 and passes through the point (2,-5) <br> which is the equation of the line
dimulka [17.4K]

We will be using the Point Slope formula which is y-y_{1} =m(x-x_{1} )

The information we are given is that m = -4 and the point is (2,-5), so we can input it into the equation.

y- (-5) = -4(x-2)

This simplifies into y+5 = -4x +8

Then we can subtract 5 from each side to get the answer:

y = 4x+3
