Answer:
1.Perpendicular
2. Parallel
3. Parallel
4.
Step-by-step explanation:
If two lines are parallel, slope is equal
If perpendicular, product of slopes is -1
y = mx + c is the general equation of a line form
m represents slope
1. slope is -1 and 1, they are perpendicular
2. Slope is 5 in both cases, they are parallel
3. slope is equal; equation ii is same as i if rewritten
They are parallel

Three students Tahat, Promi and Kabi, Appeared at an examination. Promi secured 11 marks less than Tahat, 5 marks more than kabi and again. Tahat's marks were 75% of the sum of Promi and Kabi's marks. Find out their individual marks
Answer: Tahat= 40.5 marks Promi =29.5 marks, Kabi =24.5 marks
Step-by-step explanation:
Step 1
Let the marks be represented as x+11, x and x-5 for Tahat, Promi and Kabi respectively
and Tahat's marks which was 75% of the sum of Promi and Kabi's marks be expressed as
x+11 = 75/100(x + x-5)
Step 2 --- Solving
x+11 = 75/100(x + x-5)
x+ 11 = 3/4(2x-5)
x+11= 6x-15/4
4x+44=6x-15
44+15=2x
x= 59/2= 29.5,
A) x= Promi's mark was 29.5
B)Promi secured 5 marks more than kabi
Therefore, Kabi's mark was 5 marks less than Promi
= x-5
29.5- 5= 24.5 marks
C)Promi secured 11 marks less than Tahat, Therefore Tahat marks were 11 marks more than Promi
x+11= 29.5 + 11= 40.5
44. Find the arc length on a circle with radius =5 inches and a central angle of pi/3 help plsss
Answer:
Step-by-step explanation:
Because your angle is in radians, I'm assuming we can use the pre-calculus version of the arc length formula which is
s = rt where s is the arc length, r is radians, and t is the angle in radian measure. Filling in accordingly:
[tex]s=5(\frac{\pi}{3})[/tex] so
[tex]s=\frac{5\pi}{3}[/tex] inches

How do I find the measure of angle H?
Answer: 110 degrees
Step-by-step explanation:
Similar polygons have the exact same angles. So we can fill in 60 for angle E, because it matches up with angle A.
The angles in a quadrilateral add to 360 degrees.
So 60 + 100 + 90 + Angle H = 360
If we solve for angle H, we get that angle H = 110 degrees.

9+3|5-x|=24
What is the lines for and how do I solve X with them?
Answer:
the lines represent absolute value bars
[tex]x=0,10[/tex]
Step-by-step explanation:
STEP 1: Move all terms not containing |5−x| to the right side of the equation.
[tex]3|5-x|=15[/tex]
STEP 2: Divide each term by 3 and simplify.
[tex]|5-x|=5[/tex]
STEP 3: Remove the absolute value term. This creates a ± on the right side of the equation because |x|=±x.
5-x=±5
STEP 4: Set up the positive portion of the ± solution.
[tex]5-x=5[/tex]
STEP 5: Solve the first equation for x.
[tex]x=0[/tex]
STEP 6: Set up the negative portion of the ± solution.
[tex]5-x=-5[/tex]
STEP 7: Solve the second equation for x.
[tex]x=10[/tex]
NOTE: The solution to the equation includes both the positive and negative portions of the solution.

in an examination ,80%examines passed in English ,70%in mathematics and 60% in both subject if 45 examines failed in both find the number of examines who passed only one subject also the number of examines who failed mathematics
Answer:
135 and 135
Step-by-step explanation:
The computation is shown below:
The number of examiners who passed in only one subject is as follows
= n(E) - n(E ∩M) + n(M) - n(E ∩M)
= (80 - 60 + 70 - 60)%
= 30%
Now the number of students who passed in minimum one subject is
n(E∪M) = n(E) + n(M) - n(E ∩M)
= 80 - + 70 - 60
= 90%
Now the number of students who failed in both subjects is
= 100 - 90%
= 10% of total students
= 45
So total number of students appeared for this 450
So, those who passed only one subject is
= 450 × 30%
= 135
Now the Number of students who failed in mathematics is
= 100% - Passed in Mathematics
= 100% - 70%
= 30% of 450
= 135

Based on the given figure, determine the angles that show congruent alternate exterior angles
Answer:
Angle 1 and angle 8
Angle 2 and angle 7
Step-by-step explanation:
Alternate exterior angles are angles positioned alternating each other along the transversal, where both angles are found outside the two parallel lines cut across by the transversal.
Thus from the diagram given, the following are alternate exterior angles that are congruent:
Angle 1 and angle 8
Angle 2 and angle 7

Explanation:
Solving Inequality is almost the same as equation. However, you have to know one thing about solving an Inequality.
That is whenever you move the negative coefficient of the variable, you have to swap the sign of Inequality.
[tex]-\frac{1}{2}x<-12[/tex]
Reminder that
[tex]-\frac{1}{2}x=-\frac{x}{2}[/tex]
We use negative x above 2 instead (Easier in solving)
[tex]-\frac{x}{2}<-12[/tex]
Then we move 2 to divide -12.
[tex]-x<-12(2)\\-x<-24[/tex]
Because the coefficient for x is in negative. We move -1 to divide -24 as we get 24 (Because negative divide negative = positive)
But remember that "whenever you move the negative coefficient of the variable, you have to swap the sign of Inequality."
So we change from < to > instead.
[tex]x>24[/tex]

The total cost of bag and an umbrella is Rs 2000.If the cost of the bag is Rs 1000 less five times the cost of the umbrella ,find the cost of each of these two items.
Answer:
The bag costs 1500, while the umbrella cost 500
Step-by-step explanation:
Let the cost of the bag be b and the cost of the umbrella be u
Total cost is;
b + u = 2,000 •••••(i)
From the second part of the question;
b = 5u-1000 ••••••(ii)
Substitute ii into i
5u-1000 + u = 2000
6u = 2000 + 1000
6u = 3000
u = 3000/6
u = 500
To get b, substitute the value of u into equation ii
b = 5(500)-1000
b = 2500-1000
b = 1500
