Answer: Let's call the height of the steeple "h". We can use the tangent function to set up an equation involving the angles of elevation:
tan(40°) = h / x
tan(49° 40') = (h + y) / x
where "x" is the distance from the point to the base of the steeple, and "y" is the height of the point above the ground.
We are given that the distance from the point to the church is 48 feet, so we can use the Pythagorean theorem to find the value of "y":
y^2 = x^2 - 48^2
We can substitute this expression for "y" into the second equation above:
tan(49° 40') = (h + √(x^2 - 48^2)) / x
We can now solve this equation for "h":
h = x tan(49° 40') - x √(1 + tan^2(49° 40')) + 48 tan(40°)
Plugging in the values for the angles and solving for "h", we get:
h ≈ 83.9 feet
Therefore, the height of the steeple is approximately 83.9 feet.

A softball team has 20 players. How many 9 player batting orders are possible?
There are 184,756 possible 9 player batting orders for a softball team with 20 players.
The formula to calculate the combination number of possible batting orders for a team with n players is n!/(n-r)! where n = the total number of players, and r = the number of players in the batting order. Therefore, for a softball team with 20 players, the number of possible 9 player batting orders is 20!/(20-9)! = 184,756.
20! = 20 × 19 × 18 × 17 × 16 × 15 × 14 × 13 × 12 × 11 × 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1
(20-9)! = (20 - 9) × (19 - 9) × (18 - 9) × (17 - 9) × (16 - 9) × (15 - 9) × (14 - 9) × (13 - 9) × (12 - 9) × (11 - 9) × (10 - 9) × (9 - 9)
20!/(20-9)! = 184,756
Therefore, there are 184,756 possible 9 player batting orders for a softball team with 20 players.

Find the common ratio of the geometric sequence -7, -42, -252,. −7,−42,−252,
the common ratio of the geometeric sequence -7, -42, -252 is 6.
A geometric sequence is a sequence of numbers where each term is obtained by multiplying the previous term by a fixed non-zero constant, called the common ratio. We can find the common ratio (r) of the sequence -7, -42, -252 by dividing any term by its previous term. For example:
-42 / (-7) = 6
-252 / (-42) = 6
Since the ratio is the same for both, we can conclude that the common ratio is 6. Therefore, each term is obtained by multiplying the previous term by 6.
To check, we can multiply any term by 6 to obtain the next term in the sequence. For example:
-7 * 6 = -42
-42 * 6 = -252
So, the common ratio of the sequence -7, -42, -252 is 6.

A bottle of apple juice has 25 ounces. Find the number of quarts of apple juice in a case of 24 bottles
There are 18.75 quarts of apple juice in a case of 24 bottles.
To calculate the number of quarts of apple juice in a case of 24 bottles, we must first calculate the number of ounces in the case. To do this, we can use the formula:
Total Ounces = Number of Bottles x Ounces per Bottle
Total Ounces = 24 x 25
Total Ounces = 600
Now that we have the total ounces of apple juice in the case, we can convert this to quarts using the formula:
Quarts = Ounces ÷ 32
Quarts = 600 ÷ 32
Quarts = 18.75
Therefore, there are 18.75 quarts of apple juice in a case of 24 bottles.

Using distance formula, the triangle ABC is a scalene triangle
What is triangle ABCTo classify the triangle, we need to determine whether its sides are equal in length (in which case it's equilateral or isosceles), or whether they are all different lengths (in which case it's scalene). We can use the distance formula to calculate the length of each side of the triangle, as follows:
The distance formula gives us the distance between two points (x1, y1) and (x2, y2) in the coordinate plane:
d = √[(x2 - x1)^2 + (y2 - y1)^2]
Using this formula, we can find the length of each side of triangle ABC:
AB = √[(4-1)^2 + (4-0)^2] = √(9 + 16) = √25 = 5
BC = √[(6-4)^2 + (2-4)^2] = √(4 + 4) = 2√2
AC = √[(6-1)^2 + (2-0)^2] = √(25 + 4) = √29
We can see that AB = 5, BC = 2√2, and AC = √29. Since all three sides have different lengths, the triangle is scalene.
Note that the midpoints of the sides AB and BC are not relevant for determining the type of triangle. Also, it's not accurate to say that the midpoint of AB is (4/3, 2), as the coordinates of the midpoint are actually ((1+4)/2, (0+4)/2) = (2.5, 2), and similarly for the midpoint of BC.

Answer:
SAS proves that these triangles are congruent.
A person tosses from atop a cliff a people straight downward with an initial velocity of -9. 0 meters per second, after 50 seconds, how far beneath the cliff is the people?
After 50 seconds, the person has fallen approximately 2252.5 meters below the cliff.
Assuming no air resistance, we can use the formula for distance traveled by an object under constant acceleration:
d = v_i * t + (1/2) * a * t²
where d is the distance traveled, v_i is the initial velocity, t is the time, and a is the acceleration.
In this case, the initial velocity is -9.0 m/s (negative since it is downward), and the time is 50 seconds. The acceleration due to gravity is approximately -9.81 m/s².
Substituting the given values into the formula, we get:
d = -9.0 m/s * 50 s + (1/2) * (-9.81 m/s²) * (50 s)²
≈ -2252.5 m
Therefore, the person is approximately 2252.5 meters beneath the cliff after 50 seconds.

The required circumference of the given circle is 45.27 cm approx.
What is circumference?In geometry, the perimeter of a circle or ellipse is its circumference. In other words, the circumference would equal the length of the arc if the circle were expanded up and straightened out to a line segment.
The term "perimeter" is most frequently used to describe the radius of any closed shape.
The circumference of a circle is the length around its periphery.
It is similar to the edges of other shapes, including squares.
It can be viewed as the line that defines the shape.
So, calculate the diameter using the Pythagorean theorem as follows:
h² = a² + b²
h² = 8² + 12²
h² = 64 + 144
h² = 208
h = √208
h = 14.42
Now, calculate the circumference as follows:
Radius = 14.42/2 = 7.21
Now,

Therefore, the measure of angle 1 is 40°.
What does a mathematical angle mean?Two rays (half-lines) that share a terminal are combined to form an angle. In contrast, the rays are variously referred to as the angle's legs and its arms, with the latter serving as the angle's vertex.
The measure of an inscribed angle is half the measure of its intercepted arc. Therefore, we can use this property to find the measure of angle 1.
If mAB = 80°, then arc AB is also 80° because an inscribed angle intercepts an arc with the same measure as the angle. Therefore, the measure of arc AB is 80°.
Since angle 1 is an inscribed angle that intercepts arc AB, its measure is half the measure of arc AB. Therefore, we can find the measure of angle 1 as follows:
m∠1 = (1/2) x m arc AB
m∠1 = (1/2) x 80°
m∠1 = 40°
Therefore, the measure of angle 1 is 40°.

Keshawn has � x nickels and � y dimes, having a maximum of 14 coins worth a minimum of $1 combined. A maximum of 4 of the coins are nickels. Solve this system of inequalities graphically and determine one possible solution. Number\
One possible solution is Keshawn has 2 nickels and 12 dimes.
What is inequality equation?
An inequality equation is a mathematical expression that compares two values or expressions using inequality symbols such as < (less than), > (greater than), ≤ (less than or equal to), or ≥ (greater than or equal to)
To solve the system of inequalities graphically, we can plot the two inequalities on the coordinate plane and shade the region that satisfies both inequalities. Let x be the number of nickels and y be the number of dimes.
The first inequality represents the maximum number of coins:
x + y ≤ 14
The second inequality represents the minimum value of the coins:
0.05x + 0.1y ≥ 1
We can rewrite this inequality as:
x + 2y ≥ 20
Now we can plot these two inequalities on the coordinate plane:
Draw a horizontal line for x + y = 14.
Draw a diagonal line with negative slope for x + 2y = 20.
Shade the region below the diagonal line and to the left of the horizontal line.
The shaded region represents the feasible region that satisfies both inequalities. We also know that x ≤ 4 since a maximum of 4 coins are nickels.
One possible solution that lies in the shaded region and satisfies the constraint x ≤ 4 is (x, y) = (2, 12). This means Keshawn has 2 nickels and 12 dimes. We can check that this solution satisfies both inequalities:
2 + 12 = 14 (maximum number of coins)
0.05(2) + 0.1(12) = 1.2 ≥ 1 (minimum value of the coins)
Therefore, one possible solution is Keshawn has 2 nickels and 12 dimes.

Answer:
Step-by-step explanation:
To determine which size of shampoo is the better buy, we need to calculate the unit price, which is the price per ounce for each size.
For the regular size, the unit price is:
$8.00 / 20 oz = $0.40/oz
For the economy size, the unit price is:
$10.00 / 40 oz = $0.25/oz
Since the unit price for the economy size is lower than the unit price for the regular size, the economy size is the better buy.
Therefore, the economy size of shampoo is the better buy.

To factor 12x² - 8x - 15 by grouping, we need to split the middle term -8x into two terms whose sum is -8x and whose product is -180 (the product of 12 and -15).
We can do this by splitting -8x into -18x and +10x:

P (none are caused by aggressive driving) = _____
Answer : The probability that none of the 3 accidents are caused by aggressive driving is 0.085, according to the American Automobile Association (AAA).
The probability of an accident being caused by aggressive driving is 56%, or 0.56. Therefore, the probability of an accident NOT being caused by aggressive driving is 1 - 0.56 = 0.44. Since the accidents are chosen at random, we can assume that they are independent events. Therefore, we can multiply the probabilities together to find the overall probability.
For part 1, we want to find the probability that none of the 3 accidents are caused by aggressive driving. This means we want the probability of an accident not being caused by aggressive driving (0.44) to happen 3 times in a row:
P(none are caused by aggressive driving) = 0.44 * 0.44 * 0.44 = 0.085184

The surface area of something determines its overall dimensions. The internal water volume of a cuboid is given by the total of the borders for each of its six rectangular edges.
Here,
We must first calculate the areas of the three shapes in order to add them up to get the area of the territory.
Triangle 1: The height is equal to the distance of the y-coordinates of the x-axis (which is 0) and the y-coordinates of (3,6), which is 6. Consequently, the triangle's size is:
=> 1/2 * base * height
= >1/2 * 3 * 6 = 9
The segment between the x-axis and the location where the line y=10-x meets the x-axis, which is the base in triangle 2 (10,0).
Triangle 2:
=> 1/2 * base * height = 1/2 * 4 * 1 = 2
Trapezoid:
The three shapes' combined regions result in:
=> 9 + 2 + 13.5 = 24.5
The region is 24.5 square units in size and is circumscribed by the x-axis, lines x=2, x=6, lines y=x+3, and y=10-x.
