I need this really fast can someone help me outMalik jogged 2 miles in 20 minutes. What was his rate in miles per hour?

Blababa [14]

It would be 6 miles per hour.

mph is a unit for speed. And the formula for speed is s=distance /time

So the distance is 2 miles
And the time is 20 minutes

*for this question you need to convert the minutes to hours to get the right units

20mins =0.3 hours (approx) [20/60 to get it in hours]

2 miles/0.3 hours ≈ 6 mph

The purple pathers helipad is 1/3 of a mile from the control center we'll drop the food when it's 1/4 of the way there how many

AlexFokin [52]

Answer:

1/12 of a mile.

Step-by-step explanation:

1. Find a common denominator. In this instance, we can use the denominator of 12 because both 3 and 4 are multiples of 12.

2. Multiply each fraction (numerator and denominator) to convert them.

1/3(4/4) = 4/12

1/4(3/3) = 3/12

3. Subtract.

4/12－3/12 = 1/12

REALLY NEED HELP ASAP!!!!!!!

Answer: OPTION C

Step-by-step explanation:

There are some transformations for a function f(x). Some of them are shown below:

1. If $f(x)+k$ , the function is shifted up "k" units.

2. If $f(x)-k$ , the function is shifted down "k" units.

3. If $f(x+k)$ , the function is shifted left "k" units.

4. If $f(x-k)$ , the function is shifted right "k" units.

In this case you know that the function "g" is the transformation of the function "f".

Observe that the function "f" intersects the y-axis at:

$y=2$

And the function "g" intersects the y-axis at:

$y=-2$

Therefore, since both functions are 4 units apart, you can conclude that the function "f" was shifted down 4 units to get the function "g".

Then, the rule that shows that transformation is:

$g(x)=f(x)-4$

(f/g)(x)and (f/g)(7)

Phoenix [80]

Answer:

$(\frac{f}{g})(x)=\frac{f(x)}{g(x)}\\\\(\frac{f}{g})(7)=\frac{f(7)}{g(7)}$

Step-by-step explanation:

Division operation of function: $If\ f(x)\ and\ g(x)\ are\ two\ functions\ then\ (\frac{f}{g})(x)=\frac{f(x)}{g(x)}$

$Here\ we\ have\ to\ find\ (\frac{f}{g})(7)\\\\(\frac{f}{g})(7)=\frac{f(7)}{g(7)}$

Example:

$Take\ f(x)=3x^2+1,\ g(x)=x+1\\\\(\frac{f}{g})(x)=\frac{f(x)}{g(x)}\\\\(\frac{f}{g})(x)=\frac{3x^2+1}{x+1}\\\\f(7)=3\times 7^2+1\\\\f(7)=3\times 49+1\\\\f(7)=148\\\\g(7)=7+1\\\\g(7)=8\\\\(\frac{f}{g})(7)=\frac{f(7)}{g(7)}\\\\(\frac{f}{g})(x)=\frac{148}{8}$
