In the 75th Congress (1937−1939) there were in the Senate 75 Democrats, 17 Republicans, and 4 members of other parties. Suppose
ira [324]

Answer:

42 Democrats members

12 Republicans members

2 other parties members

Step-by-step explanation:

We know that there are a total number of voters of

  • 75 (democrats)+17 (Republicans)+ 4( Other parties)=  96 voters

And we know that the bill has passed with 16 nore votes in favor that against, so let's calculate how many votes in favor of the bill we have:

  • 96 Votes = F (votes in Favor)+ A (votes against)

also: F= A+16= A = F-16, so:

  • 96= F+A= F+F-16 => F= 56 votes in favor of the bill

Thos 56 votes are the sum of the votes in favor from all the parties:

56 = D (votes in favor of democrats)+R ((votes in favor of Republicans)+OTH (votes in favor of other parties)

=> 56= D+R+OTH (A)

also democrat's votes in favor are three times the sum of non-democrat's votes in favor:

  • D= 3*( R+OTH) => OTH= D/3-R

and we have 30 more democrats thar republicans voting in favor:

  • D= R+30 => R=D-30

if we replace in the (A) formula:

56 = D+R+OTH => 56= D+D-30+D/3-D+30 =>

  • 56=4/3*D => D=42 (DEMOCRATS VOTES IN FAVOR)
  • R= D-30 => R= 12 (REPUBLICAN VOTES IN FAVOR)
  • OTH= D/3-R= 14-12= 2 (OTHER PARTIE'S VOTES IN FAVOR)

Can someone help me with this!! I’ve been stuck for awhile!!
scoundrel [369]

Answer:

(C) h = \frac{2a}{b}

Step-by-step explanation:

Here we have the formula for the area of a triangle: A = \frac{1}{2}bh. Our goal is to isolate h on one side of the equation.

To do this, let’s treat the rest of the equation as if there were no variables.

Multiply both sides by 2:

2a = bh

Divide both sides by b:

\frac{2a}{b} = h

Hope this helped!
