<h3>Answer: 176.6</h3>

Work Shown:

$b^2 = a^2 + c^2 - 2*a*c*\cos(B)\\\\b^2 = 150^2 + 30^2 - 2*150*30*\cos(150)\\\\b^2 \approx 31194.22863406\\\\b \approx \sqrt{31194.22863406}\\\\b \approx 176.618879608211\\\\b \approx 176.6\\\\$

A baseball team has won 8 out of the first 20 games and has 40 games remaining. The team needs a winning percentage of 62.5% mak

dimaraw [331]

Answer:

30 More Games for Playoffs | Win Percentage of 40% in Playoffs

Step-by-step explanation:

We find the total amount of games by adding first 20 and 40 remaining

This will leave us with 60 games

In order to calculate the playoff, we would have to calculate 62.50% in those 60 games.

62.50% is 5/8, we divide 60 by 8 and get 7.50

We multiply both sides by 7.50 and get 37.50/60

We subtract 8 from 37.50 and get 29.50

We round it to the nearest ones and get 30

In order to win the game they would need to win 30 more games

To calculate the final win percentage, we would add 2 and 3, which would give us 5.

After winning 2 and losing 3,

it would give us 2/5,

which in percentage is 40%

Find the inequality for this graph

Arada [10]

ANSWER

$y \geqslant - 2x - 5$

EXPLANATION

First we need to find the equation of the boundary line which passes through (-1,-3) with a y-intercept of -5.

The slope of this line is

$m = \frac{ -5 - - 3}{0 - - 1} = - 2$

The equation of this line is

$y = - 2x - 5$

Since the boundary line is solid and the upper half plane is shaded the required inequality is

$y \geqslant - 2x - 5$
