8) Tom climbs 25 feet into the pear tree and pulls a pear from the tree. He throws it with an upward
velocity of 30 feet/second. How long will the pear be in the air if his Dad sees him and catches it at 6 feet above the ground?

Answers

The distance the pear will be in the air if his Dad sees him and catches if at 6 feet above the ground is 19/30 meters.

How to calculate distance?

The term distance can be defined as a numerical qualitative measurement of how far apart points are from each other.

Distance is defined by the formula

d=v*t

The given parameters are:

v=30

s=6

height=25

Applying these parameters into the formula

d=30*t

d=30t

If the Dad stands 6 feet above the ground, we have

[tex]\frac{25-6}{30}[/tex]

=[tex]\frac{19}{30}[/tex]

Therefore the pear will be 19/30 feet in the air if the Dad sees him and catches it at 6 feet above the ground.

Cameron is deciding between two landscaping companies for his place of business.
Company A charges $25 per hour and a $300 equipment fee. Company B charges $55
per hour and a $150 equipment fee. Let A represent the amount Company A would
charge for t hours of landscaping, and let B represent the amount Company B would
charge for t hours of landscaping. Write an equation for each situation, in terms of t,
and determine the interval of hours, t, for which Company A is cheaper than
Company B.

Answers

Answer:

A = 25t + 300

B = 55t + 150

Less than 5 hours, company B would be cheaper. At 5 hours the cost is equal. After 5 hours, company A would be cheaper.

Step-by-step explanation:

Company B would be cheaper for lower hours.

The the two equation equal to each other and solve for to find out when the costs will be equal.

25t + 300 = 55t + 150 Subtract 25t from both sides

300 = 30t + 150 Subtract 150 from both sides

150 = 30t Divide both sides by 30

5 = t

At 5 hours the cost are the same, after 5 hours company A would be cheaper.

Answers

The average rate of change of the function at the interval x = 5 to x = 9 is 1.25

How to determine the average rate of change

The interval is given as

x = 5 to x = 9

From the question (see attachment), we have the following parameters that can be used in our computation:

x = 5 and y = 15

x = 9 and y = 20

This means that

f(5) = 15 and f(9) = 20

The average rate of change is then calculated as

Average rate of change = [f(9) - f(5)]/[9 - 5]

Substitute the known values in the above equation, so, we have the following representation

Average rate of change = [20 - 15]/[9 - 5]

Evaluate

Average rate of change = 1.25

A certain vending machine offers 20-ounce bottles of soda for $1.50. The number of bottles X bought from the machine on any day is a random variable with mean 50 and standard deviation 15. Let the random variable Y equal the total revenue from this machine on a given day. Assume that the machine works properly and that no sodas are stolen from the machine. What are the mean and standard deviation of Y?

Answers

The mean and standard deviation of a random variable can be used to describe the distribution of its possible values. In this case, the mean of the random variable X represents the average number of bottles of soda that are bought from the vending machine on a given day, and the standard deviation represents the amount of variation in the number of bottles bought from one day to the next.

To find the mean and standard deviation of the random variable Y, which represents the total revenue from the vending machine on a given day, you will need to use the mean and standard deviation of X and the price per bottle of soda.

The mean of Y can be calculated using the formula:

mean of Y = mean of X * price per bottle

Plugging in the given values, we get:

mean of Y = 50 * $1.50 = $75

So the mean of the random variable Y, which represents the total revenue from the vending machine on a given day, is $75.

The standard deviation of Y can be calculated using the formula:

standard deviation of Y = standard deviation of X * price per bottle

Plugging in the given values, we get:

standard deviation of Y = 15 * $1.50 = $22.50

So the standard deviation of the random variable Y, which represents the total revenue from the vending machine on a given day, is $22.50.

Therefore, the mean and standard deviation of Y, the total revenue from the vending machine on a given day, are $75 and $22.50, respectively.

How to calculate the value of x(angle)?

A straight line's total number of angles adds up to 180°. Supplementary angles are two angles whose sums equal 180 degrees. Angles are referred to as neighbouring if they have a similar vertex and side.A straight angle in mathematics is one with a degree value of 180. Because it resembles a straight line, it is called straight.Angles in a straight line are the total of all the angles that can be arranged in a straight line. Straight line angles add up to 180°.

The angle of the straight line = 180°

156° + x = 180°

x = 180° - 156°

x = 24°

Answer:

Not parallel.

Step-by-step explanation:

Given:

m∠9 = 110°m∠8 = 70°

Linear Pair

Two adjacent angles that sum to 180° (two angles which when combined together form a straight line).

Angles 9 and 10 form a linear pair:

⇒ m∠9 + m∠10 = 180°

⇒ 110° + m∠10 = 180°

⇒ m∠10 = 70°

Angles 7 and 8 form a linear pair:

⇒ m∠7 + m∠8 = 180°

⇒ m∠7 + 70° = 180°

⇒ m∠7 = 110°

Vertical Angles Theorem

When two straight lines intersect, the opposite vertical angles are congruent.

Corresponding Angles Postulate

When a straight line intersects two parallel straight lines, the resulting corresponding angles are congruent.

As line p is parallel to line q, and according to the vertical angles theorem and the corresponding angles postulate:

m∠1 = m∠6 = m∠9 = m∠14 = 110°m∠2 = m∠5 = m∠10 = m∠13 = 70°m∠3 = m∠8 = m∠11 = m∠16 = 70°m∠4 = m∠7 = m∠12 = m∠15 = 110°

If line a was parallel to line b, then according to the corresponding angles postulate:

m∠1 = m∠3 = m∠6 = m∠8m∠2 = m∠4 = m∠5 = m∠7

As m∠1 ≠ m∠8 and m∠2 ≠ m∠7 then lines a and b are not parallel.

What is PPG Statistics?

The average number of points a player scores in a game of a sport, over the course of a series of games, a season, or a career, is known as points per game, or PPG, and it is an important statistic. By dividing the total points by the number of games, it is calculated. Basketball and ice hockey are two sports that frequently use PPG statistics.

First, consider the PPG of the current leader of the season from among the two basketball players.

The total number of points obtained by the current leader is equal to 2112.

The total number of games played by the current leader is equal to 77.

The points per game obtained by the current leader can be calculated as follows,

PPG = Total Points Obtained / Total Number of Games

[tex]\implies PPG=\frac{2112}{77}\\\implies PPG=27.42[/tex]

Now, consider the PPG of the second place player for the season.

The total number of points obtained by the second place player is equal to 2020.

The total number of games played by the second place player is equal to 74.

The points per game obtained by the second place player can be calculated as follows,

PPG = Total Points Obtained / Total Number of Games

[tex]\implies PPG=\frac{2020}{74}\\\implies PPG=27.29[/tex]

Subtracting the points per game of both players, we get

[tex]27.42-27.29=0.13[/tex]

Hence, the leading team has scored 0.13 points per game (PPG) for the season compared to the second place player.
