8/10 = 4/5

Answer B

Answer:

B. 24 inches by 30 inches

Step-by-step explanation:

<em>Since the poser is </em><u><em>similar</em></u><em> to a rectangle measuring 8 in. by 10 in., we have to find which solution has the same proportions. </em>

<em>When simplified, 8/10 = 4/5. That is our proportion.</em>

<em>A) 2/2 does not equal 4/5</em>

<em>B) 24/30 (when simplified) = 4/5</em>

<em>B is our right answer because when </em><em>8</em><em> is multiplied by </em><em>3</em><em>, you get </em><em>24</em><em> and when </em><em>10</em><em> is multiplied by </em><em>3</em><em> as well (both multiplied by the same number to keep the proportions the same) you will get </em><em>30</em><em>.</em>

There are 450 seats in the lower level of a concert hall with b balcony seats in the upper level. So far, 170 tickets have been
slamgirl [31]

There are 400 balcony seats in the concert hall.

<u>Step-by-step explanation</u>:

Step 1 :

  • The number of lower seats = 450 seats

Total seats = Lower seats + balcony seats

Step 2 :

  • Tickets sold = 170 tickets
  • Total tickets = x

Tickets sold = 1/5 of total tickets.

⇒ 170 = (1/5)x

⇒ x = 5\times170

⇒ x = 850 tickets

∴ Total seats in the concert hall is 850.

Step 3 :

Total seats = 450 + balcony seats

850 - 450 = balcony seats

∴ balcony seats = 400

Which equation represents the line that is perpendicular to and passes through (-40,20)?
emmasim [6.3K]

The equation of the perpendicular line to the given line is: y = -5/4x - 30.

<h3>What is the Equation of Perpendicular Lines?</h3>

The slope values of two perpendicular lines are negative reciprocal of each other.

Given that the line is perpendicular to y = 4/5x+23, the slope of y = 4/5x+23 is 4/5. Negative reciprocal of 4/5 is -5/4.

Therefore, the line that is perpendicular to it would have a slope (m) of -5/4.

Plug in m = -5/4 and (x, y) = (-40, 20) into y = mx + b to find b:

20 = -5/4(-40) + b

20 = 50 + b

20 - 50 = b

b = -30

Substitute m = -5/4 and b = -30 into y = mx + b:

y = -5/4x - 30

The equation of the perpendicular line is: y = -5/4x - 30.
