17 
as in right angle one has to be 90 degree others sum should be equal to 90
so if 3x+6 and 2x-1 are smaller angle their sum should add up to 90
3x+6+2x-1=90
x=17

answer is 2x-1 is smallest=33°

5x 179∘=7x 157∘ what is x?
katen-ka-za [31]
I got X=11

Minus 7x on both sides
The equation the becomes :
-2x +179=157
Subtract 179 from both sides
Equation now is:
-2x= -22
Divide -2 on both sides
X= 11

Consider an election with 681 votes a) If there are 5 candidates, what is the smallest number of first-place votes a candidate c
joja [24]

Answer:

137 votes

Step-by-step explanation:

considering an election with 681 votes and 5 candidates up for the election

dividing the votes among'st 5 candidates

= 681 / 5 = 136.2  hence the least number of first-place votes needed by a candidate using the plurality method  would be = 137 votes

136.2 + 136.2 + 136.2 + 136.2 + 136.2 = 681 ( dividing the votes equally )

136 + 136 + 136 + 136+136 = 680

hence the remaining vote = 681 - 680 = 1

least first-place vote = 136 + 1 = 137 votes

mylen [45]

Answer:

38% probability that a randomly selected student is female or a physics major.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Desired outcomes:

Physics majors or female

10 physics majors(of which 3 are female).

12 female(the 3 female physics majors have already been counted, so we count 9)

D = 10 + 9 = 19

Total outcomes:

50 students, so T = 50

Probability

p = \frac{D}{T} = \frac{19}{50} = 0.38

38% probability that a randomly selected student is female or a physics major.
