42: 2,3,7
2 x 3 x 7 = 42

Answer:

42 = 2*3*7

Step-by-step explanation:

42 can be rewritten as 2*21, for example.  

2 is prime.  21 = 3*7.

Then 42 = 2 * 21 is also equal to:

         42 = 2*3*7. where these factors are ordered from least to greatest.  The prime factors of 42 are {2, 3, 7}.

Answer:

100.00

Step-by-step explanation:

x=number of months until the costs are the same

Suppose you have two squares, one of which is larger than the other. Suppose further that the side of the larger square is twice
TEA [102]

Answer:

Area of smaller square: y^2 yards^2,

area of larger square: 4*y^2 yards^2.

Step-by-step explanation:

If the smaller square has a side which length is y yards, its area can be calculated as the square of its side, so:

Area of smaller square = y^2

If the larger square has a side which length is twice as long as the side of the smaller square, its side is equal to 2*y yards, so its area will be:

Area of larger square = (2*y)^2 = 4*y^2

So the area of the smaller square is y^2 yards^2, and the area of the larger square is 4*y^2 yards^2.

Find the slope of the surface in the x and y-directions at the given point. h(x,y) = x2 – y2 (-3, 2, 5)
belka [17]
If h(x,y)=x^2-y^2, then you can find partial derivatives: 
\frac{dh}{dx} =2x  \\  \frac{dh}{dy} =-2y.

At point A(-3,2,5) (this is the point which lies on the surface, because 5=(-3)^2-2^2=9-4=5) these derivatives have values:

\frac{dh}{dx} |_A=2\cdot (-3)=-6 \\  \frac{dh}{dy} =-2\cdot 2=-4 -- the slopes at x and y- directions, respectively.

Answer:

  3

Step-by-step explanation:

The number of tubes can be found from an inequality that relates the number of square inches that can be painted to the number of square inches that must be painted.

Let t represent the number of tubes.

  1400t ≥ 3672 . . . . . the number of tubes that will paint at least 3672 in²

  t > 2.623 . . . . . divide by 1400

If only whole numbers of tubes are available, then ...

  3 tubes are needed to paint the ramp.
