a ladder is leaning up against a building. the bottom of the ladder is 6 feet from the building. the top of the ladder reaches the wall at a height of 8 feet. how long is the ladder?
The length of the ladder is [tex]x = \sqrt{100} =10 feet[/tex].
To find out the length of the ladder leaning against the building given the following conditions; bottom of the ladder is 6 feet from the building, and the top of the ladder reaches the wall at a height of 8 feet, the Pythagorean theorem can be utilized.
Therefore the length of the ladder is approximately 10 feet.
The Pythagorean theorem states that for a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
This can be expressed as:
[tex]c^2=a^2+b^2[/tex]
where c is the hypotenuse (the longest side of the triangle)
a and b are the other two sides
Given, the distance from the bottom of the ladder to the wall is 6 feet and the height from the ground to the top of the ladder is 8 feet.
Let the length of the ladder be x
According to the Pythagorean theorem:
[tex]x^2 = 6^2 + 8^2 x^2[/tex]
[tex]x^2 = 36 + 64x^2[/tex]
[tex]x^2 = 100[/tex]
Therefore the length of the ladder is [tex]x = \sqrt{100}= 10 feet[/tex].

*The rectangle has a perimeter of 38 meters.
*The length of the rectangle is 5 meters more
than the width.
What is the length and the width of the
rectangle?
Perimeter:
Length:
Answer:
Width of the rectangle = 7 meters
Length of the rectangle = 12 meters
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Perimeter of the rectangle = 38 meters
Width of the rectangle = w
Length of the rectangle = w + 5
Perimeter of a rectangle = 2(length + width)
38 = 2{(w + 5) + w}
38 = 2(w + 5 + w)
38 = 2(2w + 5)
38 = 4w + 10
38 - 10 = 4w
28 = 4w
w = 28/4
w = 7 meters
Width of the rectangle = w
= 7 meters
Length of the rectangle = w + 5
= 7 + 5
= 12 meters

Researchers conducted a study to determine whether the majority of community college students plan to vote in the next presidential election. They surveyed 650 randomly selected community college students and found that 55% of them plan to vote.
Which of the following are the appropriate null and alternative hypotheses for this research question?
A)
0: =0.50
: ≠0.50
B)
0: =0.50
: >0.50
C)
0: =0.55
: ≠0.55
D)
0: =0.55
: >0.55
Answer is:
B
Answer:
[tex]H_{0} = 0.5[/tex]
[tex]H_{a} > 0.5[/tex]
Option b
Step-by-step explanation:
Researchers conducted a study to determine whether the majority of community college students plan to vote in the next presidential election.
The null hypothesis is always an equalityu related to the expected, or tested value. In this question, the tested value is half of the students, a proportion of 0.5, that is: [tex]H_{0} = 0.5[/tex]
The alternate hypothesis is related to the test we are taking. In this question, we are testing if the majority of the students plan to vote, that is, if the proportion of the students that plan to vote is higher than 0.5. So [tex]H_{a} > 0.5[/tex]
So the correct answer is given by option B.
If YV = 28 in, find the length of the major arc VYX. Round to the nearest tenth ( one decimal place).
Answer:
[tex]VYX=84.3in[/tex]
Step-by-step explanation:
Given
[tex]YV = 28in[/tex]
[tex]\angle WZX = 15^\circ[/tex]
See attachment
Required
Determine the length of [tex]VYX[/tex]
First, calculate the major angle VZX
[tex]\theta = \angle VZX = 360 - \angle WZX[/tex]
[tex]\theta = \angle VZX = 360 - 15[/tex]
[tex]\theta = \angle VZX = 345[/tex]
[tex]\theta = 345[/tex]
The length of arc VYX, is:
[tex]L=\frac{\theta}{360} * 2\pi r[/tex]
Where
[tex]r = \frac{1}{2} * Diameter[/tex]
[tex]r = \frac{1}{2} * YV[/tex]
[tex]r = \frac{1}{2} * 28[/tex]
[tex]r = 14[/tex]
So:
[tex]L=\frac{\theta}{360} * 2\pi r[/tex]
[tex]L=\frac{345}{360} * 2 * \frac{22}{7} *14[/tex]
[tex]L=\frac{345}{360} * 2 * 22 *2[/tex]
[tex]L=\frac{345* 2 * 22 *2}{360}[/tex]
[tex]L=\frac{30360}{360}[/tex]
[tex]L=84.3in[/tex]
Hence, the length of VYX is:
[tex]VYX=84.3in[/tex]
The high temperatures for a week are shown. 15°, 34°, 17°, 15°, 16°, 8° Which measure of center, mean or median, would BEST represent the data?
Hey there!
The mean would probably best represent the data.
This is because the mean of data is the average, which would show what the average temperature throughout the week was.
Have a super awesome day! :)
What is the median of this set of data?
362, 187, 211, 298, 331, 250, 347, 199
Answer:
274
Step-by-step explanation:
Hey There!
So if you didnt know the median is the middle number ( in value) of the set
So first we would like to arrange the numbers in order from least to greatest
187 , 199 , 211 , 250 , 298 , 331 , 347 , 362
Then we take the middle number(s)
if there is just one then that is the answer but if there is two than we add them together and divide that by 2
In this case there are two which would be 250 and 298
So we add them together
250+298=548
Then we just divide that by 2
[tex]\frac{548}{2} =274[/tex]
Therefore the median is 274

El resultado eres: [tex]R(x) + S(x) = -6x^2 - 2x - 2[/tex]
Find the missing angle according to the Triangle Sum Theorem.
Answer:
k = 140 degrees.
The missing INTERIOR angle is 40 degrees.
Step-by-step explanation:
The missing interior angle would be 40.
Triangle angle sum theorem states the 3 interior angles of a triangle sum to 180.
64+76+40 = 180
The exterior angle theorem states the exterior angle of a triangle is equal to the sum of the two remote interior angles of the triangle.
Exterior angle k = 64+76
k= 140

Tell whether c = 3 is a solution of c + 7 = 10.
a) Yes
b) No
Answer:
a) Yes
Step-by-step explanation:
Because, 3+7=10
Answer: yes
Explanation: In this problem, to determine whether c = 3
is a solution to the equation, we substitute 3 in for c.
So we have (3) + 7 = 10.
Simplifying the left side of the equation, (3) + 7 is 10.
So we have 10 = 10 which is a true statement so our answer is yes.
