Sara drove 96 miles on 3.2 gallons of gas. How many miles can Sara drive on 12.5 gallons of gas
Blababa [14]

Answer:

375 miles

Step-by-step explanation:

Create a proportion where x is the number of miles she can drive on 12.5 gallons of gas:

\frac{96}{3.2} = \frac{x}{12.5}

Cross multiply and solve for x:

3.2x = 1200

x = 375

So, with 12.5 gallons of gas, Sara can drive 375 miles

So in my math homework lesson today we are learning “Solve One-Step Problems”. I don’t completely understand how to do it. I was
Sedaia [141]

Answer:

Step-by-step explanation:

So, in this problem, we're given the size of the of the file. We are also given the rate of change of the amount-downloaded function.

Notice how the transfer rate is in units of time (25.2 MB/s means 25.2 MB per second).

If we want to calculate how <em>long</em> it'll take to download the entire file, we have to divide the file size by the amount of the MB downloaded in one second. (This is assuming the download rate is constant, in the case it isn't constant, you would use calculus) This will find the total number of seconds needed to download the entire file.

We're essentially solving for t in the equation

400.6 = 25.2t

t = \frac{400.6}{25.2} = \frac{2003}{126} = 15.897

PLEASE PLEASEE ANSWER THE QUESTION IN THE PICTURE BELOW
KatRina [158]

Answer: Choice C

Vertex = (5, -2)

===============================================

Explanation:

Vertex form is y = a(x-h)^2 + k where the vertex itself is located at (h,k)

As the name implies, we can very quickly pull out the coordinates of the vertex without doing much math at all.

In the case of choice C, we have y=  \frac{1}{2}(x-5)^2 - 2 which is the same as y = \frac{1}{2}(x-5)^2 + (-2) and we can see that h = 5 and k = -2. Therefore, the vertex is located at (h,k) = (5, -2)
