Answer:

8 / sqrt(3)

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp / adj

tan A = BC / AC

tan 30 = BC / 8

8 tan 30 = BC

8 * sqrt(3)/3 = BC

8/3 sqrt(3) = BC

Tell weather the lines for each pair of equations are parallel perpendicular or neither y=-1/5x+6

FinnZ [79.3K]

Answer:

The slopes are neither perpendicular nor parallel.

Step-by-step explanation:

First we are going to find the slope-inercept form from the equation, -2x + 10y = 5.

Solve for y.

-2x + 10y = 5

+2x. = +2x

10y = 2x + 5

$\begin{gathered} \frac{10y}{10} = \frac{2x + 5}{10} \\ y = \frac{1}{5}x + \frac{1}{2} \end{gathered}$

So we now have

$\begin{gathered}y = \frac{1}{5}x + \frac{1}{2} \\ and \\ y = - \frac{1}{5} x + 6 \end{gathered}$

Looking at the equation above, the slopes are neither perpendicular nor parallel.

2300 people came to the ball game last week. This week there was a 13% decrease. How many people attended the football game this

Bess [88]

Answer: 2001 people attended the football game this week.

Step-by-step explanation:

Given: Total people came to the ball game = 2300

Decrease percent = 13%

Number of people attended the football game this week = p-0.13p, where p= number of people attended football last week.

for p= 2300

Number of people attended the football game this week = 2300- 0.13 x (2300)

=2300- 299

= 2001

hence, 2001 people attended the football game this week.
