What is the value of x in the triangle?
Round your final answer to the
nearest hundredth
Answers
Given:
In a right angle triangle,
Hypotenuse = 25 cm
Base = x
Angle between base and hypotenuse = 18 degrees.
To find:
The value of x.
Solution:
In a right angle triangle,
[tex]\cos \theta =\dfrac{Base}{Hypotenuse}[/tex]
In the given right triangle,
[tex]\cos (18^\circ) =\dfrac{x}{25}[/tex]
[tex]\cos (18^\circ) \times 25=x[/tex]
[tex]0.9510565 \times 25=x[/tex]
[tex]23.7764125=x[/tex]
Round the answer to the nearest hundredth (two decimal).
[tex]x=23.78[/tex]
Therefore, the value of x is about 23.78 cm.

find the positive square root of 0.00822649
Answers
Answer:
Step-by-step explanation: Although you did not specify, perhaps your were supposed to find some way to do this without a calculator. First ignore the decimals and think about 822649
900 * 900 = 810000 so the first digit of the square root is a 9
The last two numbers are 49 so the square root ends in a 7
Assume the square root is 9a7 where a is not known and expand
(907 + 10a)^2 = 822649 + other terms in a = 822649
a = 0, and we have found 822649 = 907 ^2
0.00822649 is obtained from 822649 by moving the decimal point 8 places
That tells us the square root is obtained from by moving 4 places
The answer is 0.0907......

After ordering the data set, what is the next step in drawing a box plot that shows the distribution of the amounts spent? 1. Make a dot plot for comparing. 2. Find the five boundary values. 3. Write a title for the box plot. 4. Plot and connect the end points.
Answers
Answer:
2. Find the five boundary values
Step-by-step explanation:
When drawing a dot, the steps are;
i) The data set (the list of numbers to be presented in the dot plot) are arranged in increasing order from left to right, with thee lowest value on the left and the highest value located at the right of the list
ii) The five boundary values are listed as follows;
The Minimum and Maximum Values
1) The minimum value is the lowest number in the list, which is the first number from the left
2) The maximum value is the final number on the right of the list
3) The Median, Q₂
The median number is the number which divides the data arranged in increasing number, into two equal parts
The First Quartile and Third Quartile
The numbers are divided from the median, such that the Lower half is to the left of the Median, and the Upper half is to the right of median
4) The First Quartile, Q₁ = The median of the Lower half
5) The Third Quartile, Q₂ = The median of the Upper half
iii) The box plot is then drawn with the five boundary values found above

Teresa tiene 12 años , su hermano pere tiene 7 y su padre 44. QUANTOS AÑOS TIENE Q PASAR PARA Q LA SUMA DE LAS EDADES DE TERESA Y SPERE SEAN IGUALES
Answers
Answer:
Tienen que pasar 25 años para que la suma de las edades de Teresa y Pere sean iguales a la edad de su padre.
Step-by-step explanation:
Dado que Teresa tiene 12 años, su hermano Pere tiene 7 y su padre 44, para determinar cuántos años tienen que pasar para que la suma de las edades de Teresa y Pere sean iguales a la edad de su padre se debe realizar el siguiente cálculo:
12 + 7 = 19
44 - 19 = 25
44 + 25 = 69
(12 + 25) + (7 + 25) = 37 + 32 = 69
Por lo tanto, tienen que pasar 25 años para que la suma de las edades de Teresa y Pere sean iguales a la edad de su padre.

a cylindrical container has a radius of 14 cm and I 20m high .it's curved surface is completely covered with a label . what is the area of the label in cm2 .take pie to be 22/7)
Answers
Answer:
The area of the label is 176,000 cm²
Step-by-step explanation:
The given parameters are;
The radius of the cylindrical container, r = 14 cm
The height of the cylinder, h = 20 m
The area covered with the label = The curved surface of the cylinder, A
The curved surface area of a cylinder, A = 2 × π × r × h
π = 22/7
∴ The curved surface area of the cylinder = A = 2 × 22/7 × 14 × 2000 = 176,000
A = 176,000 cm²
∴ The area of the label = The curved surface area of the cylinder = 176,000 cm².
Which of the following best describes the relationship between Angle a and angle b in the image below ( Choose all that apply)
Answers
You are correct in selecting "linear pairs" since they form a straight line.
The angles are also adjacent because they're next to each other like that. In fact, "linear pair" means "adjacent and supplementary".
The angles are not complementary because they don't add to 90 degrees. Instead, they add to 180 degrees so that's what makes them supplementary.
The angles are also not vertical angles. They would need to be opposite one another in an X configuration for this to happen. This means vertical angles cannot be adjacent, and vice versa.
2 Answers: Choice B and Choice CAngle a and angle b within the image are the linear pairs of angle within the image below.
What is the angle?It is a direction from which an individual observe something.
How to determine relationship between angles?From the figure we are able to find that angle a and angle b are the linear pair because these are formed when two lines intersect one another at one point. The angles are said to be linear if they're adjacent to every other after the intersection of the 2 lines. The sum of angles of a linear pair is often adequate to 180 degrees.
Hence the angle a and angle b are linear pairs.

1. $40
2. 10 computers
3. 300 miles
Step-by-step explanation:
1. Time between 12:00 and 2:00 is 2 hours, the difference in the money is $10, so the money earned per hour is $5. 5:00 is 3 hours from 2:00, so 25+5*3 is 40, or $40.
2. Time between 1:00 and 3:00 is 2 hours, and the difference in the numbers of computers fixed is 2, so the number of computers fixed per hour is 1. 6:00 is 3 hours from 3:00, so 7+3*1 is 10, or 10 computers.
3. Time between 6:00 and 9:00 is 3 hours and the difference in the distance is 150 miles, so the miles traveled per hour is 50. 12:00 is 3 hours from 9:00, so 150+50*3 is 300, or 300 miles.
