Tell whether the lines for the pair of equations are parallel, perpendicular or neither
y=5x+12
y=5x-1.3
The pair of lines given are parallel to each other.
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
We have the following pair of lines -
y = 5x + 12
y = 5x - 1.3
Since the slope of lines are same, both of these lines are parallel to each other.
Therefore, the pair of lines given are parallel to each other.

The Height of trees are equal after 4 years and the height is 54 inches.
What is linear equation?A linear equation is a equation which draws straight line on the plot
when plotted.
Given,
Height of tree A at the time of planting = 38 inches
Height of tree B at the time of planting = 22 inches
Each year tree A grow = 4 inches
Each year tree B grow = 8 inches
Let's make an equation for the height of the trees,
H = 38 +4t
H = 22+8t
Now the time when height of both the trees will equal
38 + 4t = 22 + 8t
4t = 16
t = 4
Hence , After 4 years the height of both the trees will equal and the height of both the trees after 4 years will be 54 inches.

Find the length of the segment connecting (-4, 3) and (-5,2). Provide
an answer accurate to the nearest tenth.
The length of the segment connecting (-4, 3) and (-5,2) is 1.4.
How to find length of segment?The length of a line segment can be measured by measuring the distance between its two endpoints.
Therefore, the length of the segment connecting (-4, 3) and (-5,2) can be found as follows:
length of the segment = √(2 - 3)² + (-5 + 4)²
length of the segment = √(-1)² + (-1)²
length of the segment = √1 + 1

If l is parallel to m, and line PQ is perpendicular to line RQ, then find the measure for each numbered angle.
m<1= _____
m<2= _____
m<3= _____
m<4= _____
The measure of the numbered angles are:
m ∠1 = 42°
m ∠2 = 48°
m ∠3 = 132°
m ∠4 = 90°
Calculating the measure of numbered anglesFrom the question, we are to determine the measure of each numbered angle.
From the given information,
Line l is parallel to line m and line PQ is perpendicular to line RQ.
Since line PQ is perpendicular to line RQ,
Then, we can write that
48° + m ∠1 = 90°
m ∠1 = 90° - 48°
m ∠1 = 42°
Also,
Since line PQ is perpendicular to line RQ,
m ∠4 = 90°
Since line l is parallel to line m,
m ∠2 = 48° (Alternate interior angles)
m ∠3 + m ∠2 = 180° (Linear pair theorem)
m ∠3 + 48° = 180°
m ∠3 = 180° - 48°
m ∠3 = 132°
Hence, the measure of angle 3 is 132°

They both Bihn and Inscoe can do same work in 3(1/13) hours.
How to solve work time problems?
Time and work problems is very easy to solve.First take the LCM of given days.It gives the total part of work.Next calculate efficiency of given persons by using the formula.Efficiency = (work)/(time)
Bihn can write one test = Eight hours
Bihn's one hour work = 1/8
Inscoe can write one test = Five hours
Inscoe's one hour work = 1/5
Bihn and Inscoe 's one hour work = 1/8 + 1/5
= (5 + 8)/40
= 13/40
Both Bihn and Inscoe can do same work in 40/13

Segment BD bisects angle ABC measure angle ABC equals 7x. The measure angle ABD equals 3x+25. Find the measurement of angle DBC
The measurement of angle DBC is 100°. It can be obtained by the properties of bisector of an angle and algebriac multiplication.
What is angle bisector?
An angle bisector is the ray or line segment that divides the angle into two equal parts.
Since the segment BD bisects angle ABC hence,
∠ABC = ∠ABD+∠DBC ..... (1)
Also, since segment BD bisects angle ABC hence,
∠ABD = ∠DBC
Use this fact in equation (1)
∠ABC = ∠ABD+∠ABD
∠ABC =2 ∠ABD
Now, substitute values and use algebriac multiplication.
7x = 2(3x+25)
7x = 6x+50
7x - 6x= 50
x=50
Now, substitute the value of x in the expression of ∠ABD.
∠ABD = 3x+25
∠ABD = 3(50)+25
∠ABD = 100
Now, since ∠ABD = ∠DBC hence, ∠DBC = 100.
Hence, the measurement of angle DBC is 100°.

the diameter to allow an elongation of 0. 38 mm therefore required diameter is 7.65 mm
Given the data in the question;
F = 11100 N
l₀ = 310 mm = 0.31 m
E = 207 GPa = 207 × 10⁹ N/m²
Δl = 0.38 mm = 0.0005 m
So, lets assume the deformation is elastic;
d₀ = √( [4l₀F] / [πEΔl] )
we substitute
d₀ = √( [4 × 0.38 × 11100] / [π × (207 × 10⁹) × 0.0005]] )
d₀ = √( 10123.2 / 172787595.947 )
d₀ = √( 5.85875 × 10⁻⁵ )
