what is the value of x ?
Answer:
x = 70
Step-by-step explanation:
Both angles must add up to 180°, by the definition of a line.
Step 1: Set up equation
x - 31 + 2x + 1 = 180
Step 2: Solve for x
3x - 30 = 180
3x = 210
x = 70

In a certain town, 25% of people commute to work by bicycle. If a person is selected randomly from the town, what are the odds against selecting someone who commutes by bicycle?
Answer:
So if 25% of the people go to work by bicycle then that means that 75% of people go to work by other means of transportation.
Therefore the odds against selecting someone who commutes by bicycle are 75% or 75/100 or 0.75.
Step-by-step explanation:
The odds against selecting someone who commutes by bicycle are 75%
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favourable outcomes / Number of sample
Given that In a certain town, 25% of people commute to work by bicycle. If a person is selected randomly from the town.

Which of the following steps is included in the construction of a perpendicular line through a point on a line? Connect arcs that are above and below the given line with a straightedge. Connect arcs that are above the original line with a straightedge. Create arcs on either side of a point that is off the given line. Create a copied angle by using the first two lines as the original angle.
Answer:
A because
Step-by-step explanation:
Which the following steps is included in the construction of a perpendicular line through a point on a line? Connect arcs that are above and below the given line with a straightedge. Connect arcs that are above the original line with a straightedge. Create arcs on either side of a point that is off the given line. Create a copied angle by using the first two lines as the original angle.
so the answer is A
The step included in the construction of a perpendicular line through a point on a line is the option:
Connect arcs that are above the original line with a straightedge
The reason for the above selection is as follows:
The steps in the construction of a perpendicular line through a point on a line include
The compass needle is placed at the point through which the perpendicular line is to pass and two arcs or equal radius, r, are drawn on either side of the point crossing the line
Increase the compass width to more than the radius, r, above, place the compass needle at the intersections of the arc and the line drawn above and draw an arc either above or below the line
Repeat the above step from the other intersection of the arc on the other side of the point on the line and draw another arc that intersects the arc in the above step, above or below the line
With the straightedge, draw a line from the given point that passes through the intersection of the arcs above or below the line to complete the construction of a perpendicular line passing through a point on a line
Therefore, the included step in the construction of a perpendicular line through a point is; Connect arcs that are above the original line with a straightedge

Solve for y:
3x - 5y = 20
Steps to solve:
3x - 5y = 20
~Subtract 3x to both sides
-5y = 20 - 3x
~Divide everything by -5
y = -4 + 3/5x
Best of Luck!
The equivalent value of the expression is y = ( 3x - 20 ) / 5
Given data ,
Let the equation be represented as A
Now , the value of A is
3x - 5y = 20
On simplifying the equation , we get
3x - 5y = 20
So , the left hand side of the equation is equated to the right hand side by the value of 20
Adding 5y on both sides , we get
3x = 20 + 5y
Subtracting 20 on both sides , we get
5y = 3x - 20
Divide by 5 on both sides , we get
y = ( 3x - 20 ) / 5
Therefore , the value of y = ( 3x - 20 ) / 5
Hence , the expression is y = ( 3x - 20 ) / 5

OK, I cut a cake vertically to make 2 congruent parts. a) Find the perimeter and area of the cross section formed by the cut. Write your answer as a decimal. The perimeter is __ inches and the area is __ square inches. b) Find the surface area of the cake that is not frosted before the cut. Round your answer to the nearest hundredth. The surface area is about __square inches.
Answer:
The perimeter is 36.5 inches.
The area is 59.5 square inches.
The surface area is about 153.94 square inches.
Step-by-step explanation:
From the figure it is clear that,
Radius of cake = 7 in
Diameter of cake = 14 in
Height = 4.25 in
We need cut the cake vertically along its diameter to make 2 congruent parts.
So, cross section is a rectangle of length 4.25 in and width 14 in.
Perimeter of rectangle is
[tex]Perimeter=2(length+width)[/tex]
[tex]Perimeter=2(4.25+14)[/tex]
[tex]Perimeter=2(18.25)[/tex]
[tex]Perimeter=36.5[/tex]
The perimeter is 36.5 inches.
Area of rectangle is
[tex]Area=lengt\times width[/tex]
[tex]Area=4.25\times 14[/tex]
[tex]Area=59.5[/tex]
The area is 59.5 square inches.
We need to find the surface area of the cake that is not frosted before the cut. It means the area of base.
Area of circle = [tex]\pi r^2[/tex]
where, r is radius.
Area of circular base = [tex]\pi (7)^2[/tex]
[tex]=49\pi [/tex]
[tex]=153.93804[/tex]
[tex]\approx 153.94[/tex]
Therefore, the surface area is about 153.94 square inches.
