Please help how to find the value of x and find the length of segment AD, the value is 5 I just need to show my work.
Answer:
9. x = 5
10. AD = 7
Step-by-step explanation:
As shown in the diagram, BD is a perpendicular bisector. And D is a point on the perpendicular bisector, meaning it is equidistant from the endpoints on the segment(points A and C). Because of this, we can say AD = CD.
We can substitute to get:
2x - 3 = x + 2
And simplify and solve:
x - 3 = 2
x = 5
AD is just 2x - 3, so we can substitute in x to find AD:
AD = 2(5) -3
AD = 10 - 3
AD = 7

justin wants to measure the thickness of a paper towel roll but his ruler is not the proper measuring device.using a full roll he takes the measurements
Answer:
Vernier caliper
Step-by-step explanation:
The paper towel is circular in shape, should he use the ruler he may come up with a value but the value may not be accurate.
Hence the measuring instrument Justin should use is a vernier caliper, which is a measuring device that can be used to measure the external diameter of the roll of paper
There are 130 people in a sport centre.
65 people use the gym.
51 people use the swimming pool.
44 people use the track.
15 people use the gym and the pool.
14 people use the pool and the track.
10 people use the gym and the track.
1 person uses all three facilities.
A person is selected at random.
What is the probability that the person uses exactly one of the facilities?
Answer:
The probability that the person uses exactly one of the facilities is 69.23%.
Step-by-step explanation:
Since there are 130 people in a sport center, of which 65 people use the gym, 51 people use the swimming pool, 44 people use the track, 15 people use the gym and the pool, 14 people use the pool and the track. , 10 people use the gym and the track and 1 person uses all three facilities, to determine, if a person is selected at random, what is the probability that the person uses exactly one of the facilities, the following calculation must be performed:
130 = 100
130 - 1 - 15 - 14 - 10 = X
130 = 100
90 = X
90 x 100/130 = X
9,000 / 130 = X
69.23 = X
Therefore, if a person is selected at random, the probability that the person uses exactly one of the facilities is 69.23%.

find the value of x. round to the nearest tenth
Answer:
using Pythagoras theorem x=32.7
Answer:
21.7
Step-by-step explanation:
In order to solve this problem, we can use trig functions. We are given the side adjacent to the 37° given and we are looking for the hypotenuse. This means that cosine function is the most suitable. Cosine is written as:
cos(θ°) = adjacent / hypotenuse
We can substitute the values we have:
cos(37°) = 17.3 / x
And rewrite the expression:
x = 17.3 / cos(37°)
Then, use a calculator to evaluate:
x = 21.66194689
This can be rounded to 21.7

Hog A is weighing 40 kilograms. Feed consumed for a month is 200 kilograms and gains 83 kilograms. What is its FCR?
Answer:
2.41
Step-by-step explanation:
The feed conversion rate measures how efficiently an animal feed to the desired output. output can include weight. the lower the FCR, the more efficient the animal is in converting feed to the desired output
FCR = feed consumed / weight gained
200 / 83 = 2.41

James scored the following points per game in the last five basketball
games he played: 31, 20, 27, 19, 28. Find the mean absolute deviation of the
number of points scored. *
A. 4.4
B. 6.2
C. 25
D. 125
The mean absolute deviation of the number of points scored is 4.4.
What is Mean Deviation?The mean deviation is used to calculate how far the values fall from the mean of the data set.
Here, Given data is 31, 20, 27, 19, 28
Mean = Sum of all data / number of terms
= (31 + 20 + 27 + 19 + 28)/5
= 125/5
= 25
Then, the deviation will be 6, 5, 2, 6, 3
Mean Deviation = Sum of Deviation / Total number of deviation
= ( 6 + 5 + 2 + 6 + 3) / 5
= 22 / 5
= 4.4
Thus, the mean absolute deviation of the number of points scored is 4.4.

Answer:
Step-by-step explanation:
(1) 6 yd 1 ft plus 9 yd 1 ft works out to 15 yd 2 ft, or 15 2/3 yd.
(2) 8' 3" less 5' 5" requires "borrowing." Since 1 ft = 12 in, your 8' 3" becomes 7' 12".
Subtracting 5' 5" from 7' 12" yields 2' 7"
(3) 25 lb 8 oz less 15 lb 10 oz also requires borrowing.
1 lb = 16 oz, so:
25 lb 8 oz = 24 lb 24 oz. Then we subtract 15 lb 10 oz from 24 lb 24 oz:
9 lb 14 oz

find the direction angle of -12i - 35j
Answer:
[tex]\theta=71.07^{\circ}[/tex]
Step-by-step explanation:
The given vector is :
v = -12i - 35j
We need to find the angle direction of v.
The general vector is given by :
v = xi+yj
The direction angle is :
[tex]\theta=\tan^{-1}(\dfrac{y}{x})[/tex]
We have, x = -12 and y = -35
So,
[tex]\theta=\tan^{-1}(\dfrac{-35}{-12})\\\\\theta=71.07^{\circ}[/tex]
So, the required direction angle is [tex]71.07^{\circ}[/tex].

Answer:
y is 107° and z is 36°
Step-by-step explanation:
73° and y are supplementary angles so they add up to 180°
Answer:
y = 107
z = 36
Step-by-step explanation:
We are given that line o is parallel to line m, and we can notice line k is a transversal through them both. Using same side interior angles, we can say that:
y + 73 = 180
and
y = 107
Next, using vertical angles, we can say that:
5z - 73 = y
We already have y = 107, so we can substitute that in:
5z - 73 = 107
5z = 180
z = 36
