Murljashka [212]

A)4/13 would be the larger number since if you were to try to add them, 4/13 = 40/130 and 3/10 = 39/130, 40/130 > 39/130

B) A rational number between them would be 39.5/130.

A student claims that only one operation is needed to calculate the length of the subtended arc when given the measure of a cent
Debora [2.8K]
Having the angle in radians and the diameter of the circle we can easily calculate the length using the following expression

Length = angle(radians)*diameter/2

With this expression we can easily deduce the perimeter of a circle (length of the full arc)

Length = Perimeter = 2*pi*r

There is only one operation involved in this process

On Saturday, the Gomez family left home to a resort in Maine. The drove at an average rate of 48 mph. ON Thursday they went back
tankabanditka [31]
If we set the unknown distance (in miles) as x, then we set up an equation according to the data, we can solve for x.

Time taken to go to resort : x/48
Time taken to return : x/40
Total time = x/48+x/40 = 11
Solve for x
common multiple between 48 and 40 = 240
so 
5x/240 + 6x/240 = 11
(5x+6x)/240 = 11
11x  = 11*240, => x=240
Distance from home to resort is 240 miles

A function has a constant halving time. What type of function does this represent?
Anna71 [15]
<span>The function which has a constant halving time is in the following form
</span>
A(t) = A_{0} ( \frac{1}{2} )^ \frac{t}{h}
Where:  A₀ is the <span>initial amount
              h   is the half life time or the halving time.
</span><span>              t    is the time
</span>              A(t) <span>the amount<span> that remains at time t
</span></span>
The previous function represents an Exponential decay<span> function.
