Answer:
51
Step-by-step explanation:
Let s represent the number of seats in a row. Then the number of rows is (s-9) and the total number of seats is ...
s(s-9) = 2142
s² -9s +4.5² = 2142 +4.5² . . . . . complete the square
(s -4.5) = √2162.25 . . . . . . . . take the positive square root
s = 4.5 +46.5 = 51 . . . . . . . add 4.5
The number of seats in each row is 51.
Answer:
C. The expression is y = 1200x + 100 , and the cost is $1,300.
Step-by-step explanation:
<u>Given</u> :
- Let y be the total cost and x be the number of TVs
- Membership costs $100
- If applied, TV costs 80% of original price
<u>Solving</u> :
- y = 1200x + 100 [given x = 1]
- y = 1200 + 100
- y = 1300
- Total cost is $1300
Midline theorem states that the cuts along the midline of a triangle creates a segment that is parallel to the base and half of the base.. The length of the line segment MN is 58 cm. Thus the option A is the correct option.
Given information-
The figure for the given problem is attached below.
In the given figure,

Thus the<em> M</em> is the midpoint of the line segment <em>AB.</em>
In the given figure,

Thus the<em> N</em> is the midpoint of the line segment <em>BC.</em>
<h3>Midline theorem</h3>
Midline theorem states that the cuts along the midline of a triangle creates a segment that is parallel to the base and half of the base.
Thus the length of the line segment<em> MN</em> can be given as,

Put the values ,


Thus the length of the line segment MN is 58 cm. Thus the option A is the correct option.
