Answer:

40⁰

Step-by-step explanation:

<em><u>Main</u></em><em><u> </u></em><em><u>principles</u></em><em><u>:</u></em>

1.Alternate angles equal

2.Vertically opposite angles are equal

If angle 2 is 40⁰, then using the second principle,angle 3 is also 40⁰

Then, using the first principle,(alternate angles/angles that form any variation of "z"), angle 6 is also 40⁰.

There are other ways to do this like using co-interior angles, straight angles and other methods, these are the easiest to understand

358 tickets to the school basketball game on Friday were sold.Students tickets were $1.50 and non-student tickets were $3.25. Th
GuDViN [60]

235 student tickets and 123 non-student tickets were sold.

Step-by-step explanation:

Given,

Total number of tickets sold = 358

Total revenue generated = $752.25

Cost of student ticket = $1.50

Cost of non-student ticket = $3.25

Let,

x represent the number of student tickets sold.

y represent the number of non-student tickets sold.

According to given statement;

x+y=358    Eqn 1

1.50x+3.25y=752.25    Eqn 2

Multiplying Eqn 1 by 1.50

1.50(x+y=358)\\1.50x+1.50y=537\ \ \ Eqn 3\\

Subtracting Eqn 3 from Eqn 2

(1.50x+3.25y)-(1.50x+1.50y)=752.25-537\\1.50x+3.25y-1.50x-1.50y=215.25\\1.75y=215.25

Dividing both sides by 1.75

\frac{1.75y}{1.75}=\frac{215.25}{1.75}\\y=123

Putting y=123 in Eqn 1

x+123=358\\x=358-123\\x=235

235 student tickets and 123 non-student tickets were sold.

Find the sum of the first 9 terms in the following
Tamiku [17]

Answer:

127 3/4

Step-by-step explanation:

you are just dividing the previous term by 2.

4th: 16 / 2 = 8

5th: 8 / 2 = 4

6th: 4 / 2 = 2

7th: 2 / 2 = 1

8th: 1 / 2 = 1/2

9th: 1/2 / 2 = 1/4

Add in groups of three to make it easier.

64 + 32 + 16 = 112

8 + 4 + 2 = 14

1 + 1/2 + 1/4 = 3/2 + 1/4 = 1 3/4

112 + 14 + 7/4 = 127 3/4
