Leila ran for president of the chess club, and she received 36 votes. There were 40 members in the club. What percentage of the
Troyanec [42]

Answer:

90% of the club member voted for Leila

Step-by-step explanation:

Leila ran for president of the chess club and she received 36 votes . The club has a total of 40 members . The percentage of the club member that voted for her can be computed below.

total member of the club = 40

number that voted for her  = 36

a%  of 40 = 36

a/100 of 40 = 36

40a/100 = 36

cross multiply

40a = 3600

divide both sides by 40

a = 3600/40

a = 90 %

90% of the club member voted for Leila

Which of the following is equivalent to the
s344n2d4d5 [400]

Step-by-step explanation:

=  {i}^{31}

=  {i}^{28}  \times  {i}^{3}

=  {( {i}^{4} )}^{7}  \times ( {i}^{2}  \times i)

= ( {i}^{2}  \times  {i}^{2} ) {}^{7}  \times  {i}^{2}  \times i

= ( - 1 \times ( - 1)) {}^{7}  \times ( - 1) \times i

=  {1}^{7}  \times ( - i)

= 1 \times ( - i)

=  - i

The answer is D.

Someone help me out please

Hey there!

150 = 8x + 6y

↠ 150 = 8x + 6(9)

↠ 8x + 6(9) = 150

↠ 8x + 54 = 150

SUBTRACT 54 to BOTH SIDES

8x + 54 - 54 = 150 - 54

CANCEL out: 54 - 54 because that gives you 0

KEEP: 150 - 54 because helps solve for x

↣150 - 54 = 96↢

NEW EQUATION: 8x = 96

DIVIDE 8 to BOTH SIDES

8x/8 = 96/8

CANCEL out: 8/8 because that gives you 1

KEEP: 96/8 because that gives the value of x

96/8 = x

x = 12

Answer: x = 12

Good luck on your assignment and enjoy your day!
