The losing candidate in a mayoral election received 10,200 votes, which represented 30% of all votes cast in the election.
ElenaW [278]

well, in the election, the losing candidate received 10200 votes, and we know that's 30% of the whole votes cast, le's say the whole amount is "x" or namely 100%.

B)

\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 10200&30\\ x&100 \end{array}\implies \cfrac{10200}{x}=\cfrac{30}{100}\implies \cfrac{10200}{x}=\cfrac{3}{10} \\\\\\ 102000=3x\implies \cfrac{102000}{3}=x\implies 34000=x

A)

Dorian's 3060 is really 30% of 10200, however, the losing candidate received 30% of the total votes cast, and that is 10200, so Dorian mistakenly is using 30% of the 30% received by the losing candidate as point of reference for her total.

In ΔBCD, \overline{BD} BD is extended through point D to point E, m∠CDE = (6x-13)^{\circ}(6x−13) ∘ , m∠BCD = (2x+10)^{\circ}(2x+
AveGali [126]

Answer:

  m∠CDE = 35°

Step-by-step explanation:

The exterior angle CDE is equal to the sum of the opposite interior angles, BCD and DBC. So, you have ...

  6x -13 = (2x+10) +(x +1)

  3x -24 = 0 . . . . . . . . . . . . subtract the right side, simplify

  x -8 = 0 . . . . . . . . . . . . . . divide by 3

  x = 8 . . . . . . . . . . . . . . . . . add 8

  6x -13 = 6·8 -13 = 35 . . . . substitute for x in the expression for CDE

The measure of angle CDE is 35°.

What is the point slope form of the line with slope 25 that passes through the point (−4, −7)?
Arisa [49]

Answer:

Option A: y+7 = 25(x+4) is the correct answer.

Step-by-step explanation:

The point-slope form of an equation of a line is given by:

y-y_1 = m(x-x_1)

Here:

m is the slope of the line

(x_1,y_1) are the coordinates of the point from which the line passes.

Now looking at the given question:

m = 25\\(x_1,y_1) = (-4,-7)

Putting the values in the general form of point-slope form of equation of line

y-(-7) = 25\{x-(-4)\}\\y+7 = 25(x+4)

Hence, the point-slope form of given line is:

y+7 = 25(x+4)

Observing the option given, it can be concluded that Option A: y+7 = 25(x+4) is the correct answer.
