you are 5 feet tall. if the angle of elevation of a tower is 23 degree and you are standing 10 feet away from the base of the tower, how tall is the tower?
The height of the tower is 9.24 feet. That is, the tower is 9.24 feet tall
Calculating the height of a towerFrom the question, we are to determine how tall the tower is
From the given information,
From a distance of 10 feet, the angle of elevation of the tower at a height 5 feet from the ground is 23 degrees.
Let x represent the length of the tower from a point 5 feet from the ground.
Thus,
The height of the tower will 5 + x feet
Now, we will determine x
Using SOH CAH TOA
tan 23° = x / 10
x = 10 × tan 23°
x = 4.24 feet
Height of the tower is 5 + x feet
Therefore,
Height of the tower = 5 + 4.24 feet
= 9.24 feet
Hence,
The height is 9.24 feet

What is an expression?Expression simply refers to the mathematical statements which have at least two terms which are related by an operator and contain either numbers, variables, or both.
In this situation, to adopt a dog from an animal shelter, you must pay $80 for vaccinations, $65 to spay or neuter the dog, and $50 for a wellness exam by a veterinarian.
Therefore, the expression to adopt x dogs will be:
= 80(x) + 65(x) + 50(x)
= 80x + 65x + 50x
= 195x
This is the cost for x dogs.

4. Which theorem would explain why TU > SV?
Answer:
B. Hınge theoremStep-by-step explanation:
We can observe:
ST = UV, marked as equal;VT = TV, common side;m∠TVU = 45° > m∠STV = 44°, as marked.According to Hınge theorem if two sides of different triangles are equal and the angles between the two sides are different, then the larger angles has greater side opposite to it.
As TU is opposite to the larger angle, and SV is opposite to smaller angle, then TU > SV.
Correct angle choice is B.
At the bakery, they have 4 and a 1/8 pies for sale. They sell 1⁄4 of a pie for$5. How many pieces do they have to sell, and how much money will they make?
The number of pieces the bakery will sell is 16 and a half. The total amount of money they will make is $82.5.
What is the number of pieces of pies to be sold?To get the number of pieces of pies that they have to sell, we need to first determine how many 1/4 pies are in 4 and 8 pieces of bread. Going by that, we can see that:
1/4x of 4 = 16.
Also, 1/4x of 1/8 = 1/2.
So, the total number of pies that they have to sell is 16 and a half.
Now if 1/4 of a pie costs $5, then 4 1/8 will be equal to 33/8 × 5 ÷ 1/4.
This is equal to 165/8 × 4 = $82.5
So, the total amount of money that the bakery will make will be $82.5.

By simplifying 2/5 + [tex]a^{2/2}[/tex] C we get the solution as (2a + 5C) / 5.
What is simplification?To simplify simply means to make anything easier. In mathematics, simplifying an equation, fraction, or problem means taking it and making it simpler. Calculations and problem-solving techniques simplify the issue.Start by resolving all of the terms enclosed in parenthesis to simplify mathematical equations using the order of operations. The exponents should then be solved, followed by any necessary multiplication. Division problems are next, followed by adding and subtracting to wrap things out.Given equation ,
2/5 + [tex]a^{2/2}[/tex] C
We know that , [tex]a^{2/2}[/tex] = a
So the equation becomes ,
2/5 a + C
By simplifying,
2a / 5 + C
= 2a / 5 + 5C / 5
By combining fractions ,
(2a + 5C) / 5

A baseball and softball facility offers batting lessons and fielding lessons to its members. There are 850 members, all of which are registered for at least one lesson. If 80% of members registered for a batting lesson and 56% registered for a fielding lesson, how many members registered for both batting and fielding?
The members who have registered for both batting and fielding are 306.
What is percentage?The Latin term "per centum," which signifies "by the hundredth," was the source of the English word "percentage." Segments with a denominator of 100 are considered percentages. In other terms, it is a relationship where the worth of the entire is always considered to be 100.
Total members = 850
Number of members registered for batting = 80%
Number of members registered for fielding = 56%
Members who participated in both,
80% of 850 + 56% of 850 - x = 850
680 +476 -x = 850

Step-by-step explanation:
Rotate 90 counter clockwise around the origin and then reflect over the c-axis
In order to get the same outcomes as a form mirrored across the y-axis and turned counterclockwise, a shape can be reflected across the x-axis and then rotated 90 degrees in a clockwise manner around the origin. This suggests a similarity between these two transformative sequences.
What does mathematics mean by reflection?
A flip is the term used in geometry to describe a reflection. The mirror image of the form is a reflection. An image can reflect through a line known as the line of reflection. When all of the points in a figure are evenly spaced away from one another, the two figures are said to reflect each other.
(X, Y) > when a form is rotated 90 degrees counterclockwise (y, -x).
When the picture is reflected across the y-axis, (x, y) > (-x, y).
When those two transformations are used, it is the same as reflecting a shape across the line y = -x, where (x, y) > (-y, -x).
For instance: After being rotated 90 degrees clockwise and reflecting across the y-axis,
(2, 1) > (1, -2) > (-1, -2); and
(2, 1) > (-1, -2)
after being reflected across the y = -x line
