71.5° should be the angle of elevation to the summit of the tree. The tree to the nearest foot is 149.4ft.
Between the horizontal line and the line of sight, an angle called the angle of elevation is created. An angle of elevation is produced when the line of sight is upward from the horizontal line. When it lies between the line of sight and the horizontal line, the angle of elevation is generated. The angle created, known as the angle of elevation, occurs when the line of sight is above the horizontal line. However, the line of sight is downward toward the horizontal line in the depression angle. The angle of elevation is the angle formed by the horizontal line of sight and the object when a person stands and looks up at something.

3.3 3.3 pounds of apples at the total cost of $18.15 $ 18.15 . if she purchases 7.9 7.9 pounds of apples at this store, how much would it cost?
The unit cost of apples is found to be $5.5 per pound. So the cost of 7.9 pounds of apple will be 43.45.
Here we have to calculate the value of a pound of apple from the given data, and then should multiply the unit value to find the cost of the given weight.
Weight of apple that was purchased = 3.3 lbs.
Cost of 3.3 lbs. of apples = 18.15
Cost of a pound of apple = Cost of apples purchased/ weight of apples purchased
= 18.15/3.3 = 5.5.
So each pound of apple will cost $5.50.
Weight of apple to be purchased = 7.9 lbs.
Cost of the apples = Weight of apples × unit price
= 7.9 × 5.50 = 43.45.
So the cost of 7.9 pounds of apple will be $43.45.

the numbers in this sequence increase by 8 each time ,what would be the closest to 100
The number in the arithmetic sequence close to 100 is 102
What is Arithmetic Progression?An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"
The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁
Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]
Given data ,
Let the arithmetic sequence be represented as A
Now , the equation will be
A = 14 , 22 , 30 , 38 ...
Now , the common difference of the AP is d = 8
The 12th term of the AP is
a₁₂ = 14 + ( 12 - 1 ) d
a₁₂ = 14 + 11 ( 8 )
a₁₂ = 14 + 88
a₁₂ = 102
Hence , the 12th term of the AP is 102

34/10
36/11
How much revenue will be produced for 45 units?
Answer: 12$
Step-by-step explanation: To find the revenue produced for 45 units, we need to find the equation that represents the relationship between the number of units sold (u) and the revenue produced (r). Based on the information given in the table, we can see that the revenue increases as the number of units sold increases. So, we can assume that there is a direct proportion between the number of units sold and the revenue produced. Therefore, we can use the equation: r = ku, where k is the constant of proportionality.
We can use any two of the given pairs (u, r) to find k. For example, using (30, 8), we have:
8 = k * 30
k = 8 / 30 = 4/15
So, the equation representing the relationship between the number of units sold and the revenue produced is: r = 4/15 * u. To find the revenue produced for 45 units, we can plug in u = 45 into the equation:
r = 4/15 * 45 = 12.
Therefore, the revenue produced for 45 units is $12.

a particular brand of shirt comes in 25 colors, has a male version and a female version, and comes in 3 sizes for each sex. how many different types of this shirt are made?
There are 150 different types of this shirt made.
There are 25 different colors, two different versions (male and female), and three different sizes for each. To calculate the total number of different types of shirt, we can use the formula: (25 colors) x (2 versions) x (3 sizes) = 150. Therefore, there are 150 different types of this shirt made.
To further illustrate, each color is available in both male and female versions, and each version has three sizes (small, medium, and large). As a result, 25 colors x 2 versions x 3 sizes = 150 different types of shirts. So, if you wanted a yellow shirt in size medium, there would be a total of 150 different types of this shirt to choose from. There are 150 different types of this shirt made.

rafi measures the big prize wheel on a game show and calculates that it has a circumference of 56.52 feet. what is the prize wheel's radius?
The radius of the prize wheel is approximately 9.06 feet.
The circle's circumference (or perimeter) = 2πR, where R is the radius of the circle. 3.14 is the approximate value of π(up to two decimal points) value of the mathematical constant.
Again, Pi (π) is a particular mathematical constant that represents the circumference to diameter ratio of any circle.
The formula for the circumference of a circle is:
C = 2 * π * r
Where "C" is the circumference, "π" is pi (approximately equal to 3.14159), and "r" is the radius.
We can rearrange this formula to solve for the radius:
r = C / (2 * π)
Plugging in the given values:
r = 56.52 / (2 * 3.14159)
r = 56.52 / 6.28318
r = 9.05849 (approximately)

When a relation is displayed in each table row represents an ordered pair with the x column representing the input values and the y column representing the output values.
True or False?
True.
In a relation, each row of a table represents an ordered pair where the x-value is in the left column (also called the domain) and the y-value is in the right column (also called the range or codomain). The x-values represent the inputs to the relation, and the y-values represent the corresponding outputs.
Relation Table RepresentationA relation is a set of ordered pairs, where the first element of each pair comes from a set called the domain and the second element comes from a set called the range or codomain. In a table representing a relation, each row represents an ordered pair where the first element (the x-value) is from the domain and the second element (the y-value) is from the range or codomain.
For example, consider the relation R = {(1, 3), (2, 5), (3, 7)}. In a table representing R, the x column represents the first element of each ordered pair (i.e., the domain) and the y column represents the second element of each ordered pair (i.e., the range or codomain).
The first row of the table would be (1, 3), where 1 is the input (x-value) and 3 is the output (y-value) for the relation R. The second row of the table would be (2, 5), where 2 is the input (x-value) and 5 is the output (y-value) for the relation R. And so on for the rest of the rows in the table.
Therefore, each row of a table representing a relation does indeed represent an ordered pair, where the x column represents the input values and the y column represents the output values.

Lisa buys her children four shirts and three pairs of pants for $85.50.
She returns the next day and buys three shirts and five pairs of pants for $115.00.
This means,
We can make two equations.
4x + 3y = 85.50
3x + 5y = 115
Now,
4x + 3y = 85.50
4x = 85.50 - 3y
x = (85.50 - 3y)/4
Substituting in 3x + 5y = 115.
3 (85.50 - 3y)/4 + 5y = 115
256.5 - 9y + 20y = 460
11y = 460 - 256.6
11y = 203.4
y = 18.5
And,
x = (85.50 - 3y)/4
x = (85.50 - 55.5)/4

The only option in which B can be the limiting reagent is A/B = 1.
The molecular equation for this hypothetical reaction is 3A + 3B → 3C + 3D. To determine which reactant is the limiting reagent, we must calculate the mole ratios of the reactants. In this case, we need to compare the ratio of A to B.
If we assume that the equation is balanced, then this means that there are an equal number of moles of A and B in the reaction. Therefore, the mole ratio of A to B is 1:1 (A/B = 1).
The other given options are 2A/7B, A/4B and A/5B. All of these ratios are greater than 1, meaning that B is in excess and will not be the limiting reagent. Therefore, the only option in which B can be the limiting reagent is A/B = 1.

how many strawberries should be picked so that the probability of having exactly 2 rotten strawberries among them equals 2/35
The final answer will depend on the specific value of p.
Let's say we need to choose a number of strawberries. Then, using the binomial distribution formula, it is possible to determine the likelihood that there will be exactly 2 rotting strawberries among them:
P(exactly two spoiled strawberries) i= (n choose 2) * p^2 * (1-p)^(n-2)
where p is the probability of each strawberry being rotten.
By setting this to 2/35 and figuring out n, we get at:
2/35 = (n choose 2) * p^2 * (1-p)^(n-2)
2/35 = (n choose 2) * p^2 * (1-p)^(n-2)
(2/35) / p^2 = (n choose 2) * (1-p)^(n-2)
It should be noted that p's value is unknown and would need to be determined by estimation or historical data. The final answer will depend on the specific value of p.
