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

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
Find the length of the third side. If necessary, round to the nearest tenth.

Andrew thought he could score 25 points on an arcade game, but he only scored 17. What was Andrew's percent error? Prediction - Actual Hint: Percent error- * 100 Actual Round to the nearest percent. [?]%
Answer:
47%
Step-by-step explanation:
% error = ( (theoretical(correct) – experimental(prediction)) / theoretical(correct) ) × 100%.
% error = |17 – 25| / 17 × 100% =
% error = (8 / 17 × 100)%
% error = (800 / 17)%
% error = (47.0588235294..)%
% error ≈ 47%

Point S is located at (-9. 8). Point G is located at (-3. 3). Determine the
slope-intercept equation of line SG.
Please help :)
Answer:
y = - [tex]\frac{5}{6}[/tex] x + [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = S (- 9, 8) and (x₂, y₂ ) = G (- 3, 3)
m = [tex]\frac{3-8}{-3+9}[/tex] = - [tex]\frac{5}{6}[/tex] , then
y = - [tex]\frac{5}{6}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 3, 3 ), then
3 = [tex]\frac{5}{2}[/tex] + c ⇒ c = 3 - [tex]\frac{5}{2}[/tex] = [tex]\frac{1}{2}[/tex]
y = - [tex]\frac{5}{6}[/tex] x + [tex]\frac{1}{2}[/tex] ← equation of line

Step-by-step explanation:
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%.
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.

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

Answer:
Step-by-step explanation:
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].
