Ms. Turner drove 90 miles in March. She drove 3 times as many miles in March as she did in January. She drove 4 times as many miles in February as she did in January. How many miles did Ms. Turner drive in February?

7.5 miles

Step-by-step explanation:

I think...

In March Ms. Turner drove 90 miles. If she drove 3 times as many miles in March as she did in January, then all we need to do at this point is multiply 3 to 90.

90 × 3 = 270

So Ms. Turner drove 270 miles in January.

Ms. Turner then drove 4 times as many miles in February as she did in January, so we will do the same here.

270 × 4 = 1080

Therefore, Ms. Turner drove 1,080 miles in February.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

the answer is 9.8975

explanation:

when you multiply the "39.59" with the 25% it reduces it and shows its final discounted price. hope this !
