B is correct.

Compare the percentages:

Bush: 47.9

Gore: 48.4

I'm not so great on history.....

B. More individual voters cast their vote for Gore.

C. The contract provided changes in government that appealed to Americans at that time, leading to a majority of seats in Congress being held by Republicans.

Let the  number  of dimes  =  D

Then the number  of  nickels is  25 - D

So   we  have this

value of a nickel * number  +  value  of a dime * number  = toal value

.05 (25 - D)  +  .10 (D)   = 1.65     simplify

1.25 - .05D  + .10D  = 1.65

1.25 + .05D  = 1.65     subtract 1.25 from both sides

.05D  = .40         divide both sides  by .05

D = 8 = number of dimes

And  25 - 8  =  17   nickels

If you see closely, the line intersects at (0,0)-making this both the x and y-intercepts.

1. For this problem, recognize that the given side lengths are part of an isoceles triangle. 

It is advisable to drop the altitude to the base length of six, bisecting that side length.

By the Pythagorean Theorem, we have 7^2-3^2=y^2, y^2=40, \(y=2\sqrt{10}\).

Thus, the area of the triangle is \(\frac{1}{2}*6*2\sqrt{10}=6\sqrt{10}\)

We  have  this

tan (50°)  =  x  / 40

40 * tan (50°)  = x

The  height of the  flagpole  =

5.5   +   x   =

5.5  +  40 * tan (50°)    ≈   53.2  ft 

Nice, CPhill! 

We can solve  this  using the Law of Sines

We have   that

x / sin (73°)  = 29.6 / sin (33°)      multiply both sides by  sin (73°)

x =  29.6*sin (73°)  / sin (33°)  ≈  51.97 = 52 ft

I plan to use the quadratic formula on this equation:   x² + 2bx + (a - b)  =  0  

using     a = 1     b = 2b     c = a - b  

For the equation to have only one real solution  b² - 4ac  must be zero.

Replacing:     (2b)² - 4(1)(a - b)  =  0

                             4b² - 4a + 4b  =  0

                                             -4a  =  -4b² - 4b

Diviing by -4:                           a  =  b² + b

I hope that the variables in the equation did not confuse you with the variables in the quadratic formula.

Nice, jfan!

Hey guest! First, let's form a right triangle with two legs of 75, with 35 being the height of the building, and 75 being the distance that you are standing from the building. Next, we know that the tangent of our angle is opposite / adjacent, which means it is equivalent to:

35 / 75 = 7 / 15

Finally, to get our desired angle, we take the arctan(7/15), which will give us our desired angle. Plugging it into a calculator, we get an angle of:

62.1818607 degrees, which rounds out to 62.2 degrees 

tan50 = opposite/adjacent      opposite is height     adjacent is 40 ft     

             = height / 40        when you figure out THIS height you must add the 5.5 ft observer's height

tan 50 = 1.191754

Tan 50 is not the angle of elevation, that's arctan of that ratio. Tangent is a ratio of sides, not the angle itself. The inverse sine (arcsin)is the angle itself given the sine for example. Consequently, the inverse tangent(arctan) is the angle itself given the tangent.

Hint:

Tan 50 degrees will represent the angle of elevation. Now, write the equation.

Hope this helped!

Hint:

One root means that the equation has to be in the form of (x+#)^2=0.

Hope this helped!

Another Best Answer! Wow!!!!

Nice, EP!

Nice job, Guest!

Three angles  add to 180^o

^{a = smallest angle}

^{2a  =  2nd agle}

^{3a  = 3rd angle          a + 2a + 3a = 180         solve for 'a'   then you can figure the rest (well.....you SHOULD be able to ! )}

Remember :  The sum of angles in a triangle = 180  

   a right triangle has one 90^o angle in it

       the other two are equal                                   so      a + a  + 90 = 180^o       Solve for 'a' the two smaller angles'  measure

L = length

W = width = L-0.7

perimeter =  2L  + 2W  

                = 2L + 2 (L-0.7)  = 44.6     solve for L         then W = L-0.7   meters

Second one   :     Very Similar       2[ L   +    (L-4)] = 52     solve for L     then W = L-4  meters
