Okay. So, there will be 12 small turbines, with 3 blades on each of them. 12 * 3 is 36. Marco will need 36 wind turbine blades total. 4 of them cost $79.64. 36/4 = 9. We would multiply 79.64 by 9 to get the cost for all blades. 79.64 * 9 is 716.76. The total cost for 36 blades would be $716.76.

Hello!


If Marcos has 12 turbines with 3 blades / turbine, then 36 blades. If 4 blades cost $ 79.64, then how much do the 36 blades cost?

Let's make a simple three rule:

Blade ___ price

4 ----------- 79.64
36 --------- y


4 * y = 36 * 79.64
4y = 2,867.04
y =  \frac{2,867.04}{4}

y = 716.76

The 36 blades cost $ 716.76

write an equation for the line that passes through (5,-4) and is perpendicular to the graph of 5x -2y=-6
Vadim26 [7]

Answer:

y = (-2/5)x - 2

Step-by-step explanation:

One way to attack this problem is to interchange the coefficients of x and y and change the sign of one to +:  5x - 2y = -6 becomes 2x + 5y = c.  Solving for the slope, m, we get 5y = -2x + c first, and then y = (-2/5)x + D.

Subbing 5 for x and -4 for y, we now have -4 = (-2/5)(5) + D.

Then -4 = -2 + D, so that D = -2.

The desired equation is thus y = (-2/5)x - 2.

Check:  Does this pass through (5, -4)?  Is -4 = (-2/5)(5) - 2 true?  Yes.

Is the slope -2/5 the negative reciprocal of 5/2?  Yes, it is.
