Paul was plotting points on a graph. He was given (3,4). When he moves 3 spaces, which direction will he need to go?
Answer:
right from the y-axis
Step-by-step explanation:
The ordered pair (3, 4) is understood to be the (x, y) coordinates of the point Paul wants to plot.
__
The x-coordinate (3) is the number of spaces the point lies to the right of the y-axis.
The y-coordinate (4) is the number of spaces the point lies above the x-axis.
__
If Paul is moving 3 spaces from the y-axis, he will be moving to the right to get to where he will plot the point.

===================================================
Short Explanation:
Subtract the arcs and divide by 2 like so
angle 1 = (longerArc - shorterArc)/2
angle 1 = (100 - 30)/2
angle 1 = 70/2
angle 1 = 35 degrees
---------------------------
Longer explanation:
Refer to the diagram below. I have replaced the 100 and 30 degree arcs with A and B respectively. I've also added in the arc measures of y and z.
Note how the smaller circle arc pieces A, B, y and z all form a complete full circle. So those values add to 360. We get A+B+y+z = 360. We'll use this later.
In the diagram, I've also drawn a blue segment to form a triangle. The angle x we want to find has replaced angle 1. The angles (y+B)/2 and (z+B)/2 are found through the inscribed angle theorem.
Focus on the triangle. The three angles of any triangle always add to 180, so,
(z+B)/2 + (y+B)/2 + x = 180
we can multiply both sides by 2 and we end up with
z+B + y+B + 2x = 360
z+y+2B + 2x = 360
Since we have 360 on the right hand side of this equation, and the equation A+B+y+z = 360, this means that the left sides of each equation are the same.
We can then say the following
z+y+2B + 2x = A+B+y+z
2B+2x = A+B
2x = A+B-2B
2x = A-B
x = (A-B)/2
This is the formula used in the "short explanation" section above. In this case, A = 100 and B = 30, so
x = (A-B)/2
x = (100-30)/2
x = 70/2
x = 35
The measure of angle 1 is 35 degrees.
Side note: With that formula above, we always have A > B.
Answer:
[tex]m\angle 1 = 35^\circ[/tex]
Step-by-step explanation:
Exterior Angle of a Circle
An exterior angle of a circle is an angle whose vertex is outside a circle and the sides of the angle are secants or tangents of the circle.
Please refer to the figure below.
The measure of the exterior angle x is given by:
[tex]\displaystyle x=\frac{b-a}{2}[/tex]
Where a and b are the intercepted arcs.
We are given b=100° and a=30°, thus angle 1 is:
[tex]\displaystyle m\angle a=\frac{100°-30°}{2}[/tex]
[tex]\boxed{m\angle 1 = 35^\circ}[/tex]
8.174 rounded to nearest whole number
Answer: 8
Step-by-step explanation: Look at the first digit after the decimal point, if it is less than 5 than you do not have to do anything. In this case, it is less than five so it is closer to zero, which is why we count it and all the numbers behind it like a zero. It does not work that way for some problems! Hope this helps!
1<5, 7>5, 4<5, 4 does not change the 7. 7 makes the 1 a 2.
2 still less than 5.
So, the answer is 8
Ill pay for whoever gets this right 10 dollars (if right)
Answer:
101°
Step-by-step explanation:
[tex]50 \degree + x \degree + (180 - 151) \degree = 180 \degree \\ \\ 50 \degree + x \degree +29 \degree = 180 \degree \\ \\ x \degree +79 \degree = 180 \degree \\ \\ x \degree = 180 \degree - 79 \degree\\ \\ x = 101 \degree[/tex]
Another way:
x° + 50° = 151° (Alternate angles)
x° = 151° - 50°
x° = 101°
x = 101

80 people attended a meeting. There was x men and x women and the rest were children. How many children attended the meeting
Answer:
[tex]Children = 80 - 2x[/tex]
Step-by-step explanation:
Given
[tex]Total = 80[/tex]
[tex]Men = x[/tex]
[tex]Women = x[/tex]
Required
Determine the number of children
This is calculated using:
[tex]Total = Men + Women + Children[/tex]
Substitute values for Total, Men and Women
[tex]80 = x + x+ Children[/tex]
[tex]80 = 2x + Children[/tex]
Subtract 2x from both sides
[tex]80 - 2x = 2x -2x + Children[/tex]
[tex]80 - 2x = Children[/tex]
[tex]Children = 80 - 2x[/tex]

Perimeter = 54
Step-by-step explanation:
You can cut the polygon into different shapes. The one with a missing side is a rectangle. Cutting it results in sides 3, 8, 6 + ?, and 3. All opposite sides are equal. x =2. The perimeter, you add the sides. 3 + 6 + 3 + 2 + 6 +4 + 15 +4 +3 + 8 = 9 + 5 + 10 + 19 + 11 = 14 + 29 + 11 = 14 + 40 = 54

Part A :
A machine that bottles apple juice is set so that every 6th bottle gets a red label and every 9th bottle gets a blue cap. The machine.
Part B :
The machine is reset so that every 10th bottle gets a special gold band around the label. What number bottle will be the first to get a red label, a blue cap, and a gold band ?
Answer:
The 90th
Step-by-step explanation:
You have to find the least common multiple of 6, 9, and 10 because that will be the first one when all three are on the bottle.
The least common multiple is 90.
Assume that automobile accidents at a dangerous intersection occur according to a Poisson process at the rate of 3 accidents per week. Furthermore, the num- ber of people seriously injured in an accident has a Poisson distribution with mean 2 and is independent of the other accidents. Find the mean and standard deviation of the number of serious injuries over a one year's time.
Answer:
The mean number of serious injuries over a one year's time is of 104 and the standard deviation is of 10.2
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
In which
x is the number of sucesses
e = 2.71828 is the Euler number
[tex]\mu[/tex] is the mean in the given interval. The standard deviation is the square root of the mean.
Find the mean and standard deviation of the number of serious injuries over a one year's time.
Per week, mean [tex]\mu = 2[/tex]
A year has approximately 52 weeks, so, the mean is [tex]\mu = 2*52 = 104[/tex], and the standard deviation is [tex]\sqrt{104} = 10.2[/tex]
