Find the number of sides of a regular polygon whose each interior angle is 150 degree ...pls give step by step explaination
Answer:
12
Step-by-step explanation:
the angle is defined by equation ((n-2)*180)/n,where n is number of sides of a regular polygon
so here 180n-360=150n
30n=360
n=12

Given: p-q= pq/2.Express p in terms of q.
Here is ur perfect answer
Answer:
p = [tex]\frac{2q}{2-q}[/tex]
Step-by-step explanation:
p - q = [tex]\frac{pq}{2}[/tex] ( multiply both sides by 2 to clear the fraction )
2(p - q) = pq ← distribute parenthesis on left side
2p - 2q = pq ( subtract pq from both sides )
2p - pq - 2q = 0 ( add 2q to both sides )
2p - pq = 2q ← factor out p from each term on left side
p(2 - q) = 2q ← divide both sides by (2 - q)
p = [tex]\frac{2q}{2-q}[/tex]

Select the inequality that corresponds to the given graph. (5 points)
Answer:
3) 4x-2y (less than) -8
Answer:
Option 3: 4x - 2y < -8
Step-by-step explanation:
Given the graph of a linear inequality with a dashed line as its boundary line:
Quick Note:To start with, since the graph of the line is dashed, this means that the endpoints are not included as solutions.
Hence, we can easily rule out Option 4: 2x + 4y ≥ -16, since the solid boundary lines are used to represent linear inequalities with "≥" or "≤" symbols. Solutions:It will help to choose a test point that is not on the line, and substitute its values into the given inequality statements. Test points are used to verify whether it will satisfy the given inequality statement.
Let's use the point of origin as our test point, (0, 0). Substitute its values into the linear inequality statements in Options 1 through 3:
Option 1: 4x - 3y > -124x - 3y > -12
4(0) - 3(0) > -12
0 - 0 > -12
0 > -12 (True statement). Hence, the half-plane region that contains the test point must be shaded.
Since the point of origin is not a part of the shaded region in the given graph, then it means that the linear inequality in Option 1 is not the correct answer.
Option 2: x + 4y > 4x + 4y > 4
(0) + 4(0) > 4
0 + 0 > 4
0 > 4 (False statement). The half-plane region that doesn't contain the test point must be shaded. Hence, Option 2 may be a valid solution.
We must transform the given inequality statement into its slope-intercept form, to see whether its slope matches the graph:
x + 4y > 4
x - x + 4y > - x + 4
4y > -x + 4
Divide both sides by 4 to isolate y:
[tex]\displaystyle\mathsf{\frac{4y}{4}>\:\frac{-x\:+\:4}{4} }[/tex]
y > -¼x + 1 ⇒ This is the slope-intercept form, where it has a negative slope of m = -¼. Hence, Option 2 is not a valid answer, as the graph has a positive slope.
Option 3: 4x - 2y < - 8
4x - 2y < - 8
4(0) - 2(0) < - 8
0 - 0 < - 8
0 < -8 (False statement). Thus, the half-plane region that doesn't contain the test point must be shaded.
We must transform the given inequality statement into its slope-intercept form, to see whether its slope matches the graph:
4x - 2y < - 8
4x - 4x - 2y < -4x - 8
-2y < -4x - 8
Divide both sides by -2 to isolate y:
[tex]\displaystyle\mathsf{\frac{-2y}{-2}>\:\frac{-4x\:-\:8}{-2} }[/tex]
y < 2x + 4 ⇒ This linear inequality statement in slope-intercept form matches the given graph, as its line has a positive slope of 2.
Therefore, the correct answer is Option 3: 4x - 2y < -8.

micheal-anthony and jocelyn are both running around the track at school. michael-anthony runs 3 miles in 20mins and continues running at this pace for 1 hour. jocelyn runs 4 miles in 30 mins and continues running at this pace for1 hour. how many miles does each person each person run in an hour? who runs faster?
explanation is needed
The number of miles each person runs after an hour is;
Michael Anthony = 9 miles
Jocelyn = 8 miles
The person that runs the fastest is;
Michael Anthony with a speed of 0.15 miles per minute.
Michael-Anthony runs 3 miles in 20 minutes
Now formula for speed is;
Speed = distance/time
Thus;
Speed of Michael Anthony = 3/20 miles per minute = 0.15 miles per minute
Thus, in 1 hour = 60 minutes,
Distance covered = 3/20 × 60
Distance covered = 9 miles
Jocelyn runs 4 miles in 30 minutes
Speed of Jocelyn = 4/30 = 0.133 miles per minute
Distance covered by Jocelyn in 1 hour = 60 minutes is; 0.133 × 60 = 8 miles

Answer:
Step-by-step explanation:
4(3x+2y)+6(−2x−5y)
Use the distributive property to multiply −4 by 3x+2y.
−12x−8y+6(−2x−5y)
Use the distributive property to multiply 6 by −2x−5y.
−12x−8y−12x−30y
Combine −12x and −12x to get −24x
−24x−8y−30y
Combine −8y and −30y to get −38y.
and you get −24x−38y

Shannon ran the race slower than Patti but faster than Phan. What might her time be?
Phan: 7.7
Daniel: 7.44
Patti: 7.1
Ida: 7.501
Maisha: 7.01
Ali: 7.941
Manuel: 7.332
Since she was slower than Patti but faster than Phan, the compound inequality that models her time t is:
[tex]7.1 < t < 7.7[/tex]
An inequality is said to be compounded if it includes two terms, for example:[tex]a < x < b[/tex]
Which has the following interpretation: x is more than a and x is less than b.In this problem:
Shannon is slower than Patti, hence her time is greater than 7.1.She is also faster than Phan, hence her time is less than 7.7.Then, the inequality is:
[tex]7.1 < t < 7.7[/tex]

parallel to y = 1/5x-4 and goes through (10,-2) in point slope form
Answer:
y + 2 = [tex]\frac{1}{5}[/tex] (x - 10)
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 )
y = [tex]\frac{1}{5}[/tex] x - 4 ← is in slope- intercept form
with slope m = [tex]\frac{1}{5}[/tex]
Parallel lines have equal slopes
The equation of a line in point- slope form is
y - b = m(x - a)
Here (a, b ) = (10, - 2 ) , then
y - (- 2) = [tex]\frac{1}{5}[/tex](x - 10) , that is
y + 2 = [tex]\frac{1}{5}[/tex](x - 10) ← in point- slope form
y+5 = -3/2(x-2) in slope intercept form
Answer:
y = -3/2x -2
Step-by-step explanation:

y +5 = -3/2x +3 . . . . . eliminate parentheses
y = -3/2x -2 . . . . . . . . subtract 5
The slope-intercept form of the equation is ...
y = -3/2x -2
Answer:
[tex]y = -\frac{3}{2} x -2[/tex]
Step-by-step explanation:
