So, we've got two important and useful information:
guy's house is 9/10 miles away from the library
guy's house is 4/10 miles away from the cafe
now, the question will tell us which mathematical operation to use, it says:
how much farther than. that means comparing which means difference which means subtraction. (how much farther than=comparing=differnce=subtraction)
so now we know that we will subtract. but, subtact which number from which number? we need to subtract 4/10 from 9/10 which means it will be equal to 5/10 which can be simplified into 1/2
the answer is basically 5/10 and if you want to look smart for your teacher, you must write simplified=1/2..
hopw this helps... now.. for return i need the brainliest answer.. :) :D
Let the distance traveled by car X be x km
<span>let the distance traveled by car Y by y km </span>
<span>their paths form a right-angled triangle. </span>
<span>Let the distance between them be D km </span>
<span>D^2 = x^2 + y^2 </span>
<span>2D dD/dt = 2x dx/dt + 2y dy/dt </span>
<span>dD/dt = (x dx/dt + y dy/dt)/D </span>
<span>at the given case: </span>
<span>x = 60, y = 80 , dx/dt = 80, dy/dt = 100 </span>
<span>D^2 = 60^2 + 80^2 = 10000 </span>
<span>D = 100 </span>
<span>dD/dt = (60(80) + 80(100))/100 </span>
<span>= 128 </span>

Answer:

Step-by-step explanation:
Going by the dimensions of the given three-dimensional figure, we can conclude that the figure is that of a cube. The height, length and width are equal.
Volume of a cube is given as
, while surface area of a cube is given as 
Where, a = the side length = 5 yards
