Answer:

<em>x = 11.83°</em>

Step-by-step explanation:

<u>Equations</u>

The figure shows two parallel lines crossed by a line. We have completed the figure with another variable y. Please see the attached image.

Angles y and 4x+28 are linear, thus their sum is 180°:

y + 4x + 28 = 180

Angles y and 8x + 10 are corresponding, thus

y = 8x + 10

Substituting:

8x + 10 + 4x + 28 = 180

Simplifying:

12x + 38 = 180

Subtracting 38:

12x = 142

Dividing by 12

x = 11.83°

Step-by-step explanation:

Mechanical advantage can be defined using distances:

Mechanical advantage = input distance / output distance

Or it can be defined using forces:

Mechanical advantage = output force / input force

Solving for the output force:

Output force = mechanical advantage × input force

Plugging in values:

Output force = 2.2 × 202 N

Output force = 444.4 N

Match each scenario with the type of correlation it shows
tiny-mole [99]

Answer:

1- Positive correlation

2- Negative correlation

3- No correlation

Step-by-step explanation:

1- The more a player practices free throws, the better they will be at it and therefore will make more free throws. Thus, there is a positive correlation between the time spent practicing and the  number of free throws made.

2- Since each item bought has a cost, the more items are bought, lower will be the checking account balance. Thus, there is a negative correlation the number of items bought and the  checking account balance.

3- There is no explicit correlation between players heights and their ability to hit a baseball therefore it is fair to assume that there is no correlation between the height of baseball player and the  number of hits made
