The area of a triangle is the region enclosed between the sides of the triangle. Area of ΔABC = 1/2 × Base × Height. Let us know the basics of the area of a triangle. If ABC is an equilateral triangle, Area of ΔABC = (√3/4)a2 where a is the length of a side of the equilateral triangle.
Find the slope rise/run
Answers
Answer:
m = -1/3
Step-by-step explanation:
Find two points in order to calculate slope:
(0, 2) (3, 1)Slope (m) =
ΔY /ΔX= -1/ 3= -0.33333333333333
( ΔX = 3 – 0 = 3ΔY = 1 – 2 = -1 )Slope intercept:
y = -0.33333333333333x + 2
Answer:
Slope = - 1/3
Step-by-step explanation:
Choose the point on the right and move upwards. How many times did you move upwards until you were at the same level as the point on the left? You moved once, which means your rise is 1.
Now from the point where you are at now, move right or left depending on where the point is. In this case, it's on the left which means our run will be negative. Now move left until you reach that point on the left. How many times did you move left? You moved three times, which means your run is 3.
Rise/Run = -1/3
Slope = Rise/Run
Slope: - 1/3

Answers
Answer:

Step-by-step explanation:
substitute x in equation 2
y= 2(10) -6
y= 20 - 6
y= 14
substitute y in equation 2
14 = 2x - 6
-2x= -6-14
-2x= -20
divide both sides by -2
-20/-2
x= 10

Answer:
So to do this you need a protactor and measure it with it, then add the total
Step-by-step explanation:
explanation:
for finding the total angles in a shape you have to follow the formula
(n-2)180
which n is the number of sides
so for a pentagon you will get
3.180=540 and by dividing it into the amount of angles you will get each angle's amount
so
540/5=108 -> each angle
back to the quastion you see the angle C is 108 and we have a triangle
and angles D and B are equal so by subtracting 108 from 180 (total angles in a triangle) we get 72 which is equal to both B and D angles so by dividing it to 2 you will get 36 which is the answer
Draw and simplify the karnaugh maps of x,y,Z for (a)m0 +m1+ m5+m7. (b)F(1,3,5,4,7). (c)m0+m2+m4+m6. (d)F(0,2,4,6)
Answers
The simplified Karnaugh maps are F(A, B, C) = A’B’ + AC , F(A, B, C) = C + AB’, F(A, B, C) = C’.
What are Karnaugh Maps ?A Karnaugh map can be compared to a more advanced version of a truth table
In a K-map there are all the possible input variables and outcomes stored in cells.
It is a method to simplify and optimize Boolean expressions.
(a) m0 +m1+ m5+m7
Mapping the given function in a Karnaugh map,
The image is attached with the answer.
we can see two pairs
Pair-1 is m0 + m1
and Pair-2 is m5 + m7
= A’B’C’ + A’B’C + AB’C + ABC
= A’B’(C’ + C) + AC(B’ + B)
= A’B’ + AC
Therefore the simplified Boolean expression for the given data is
F(A, B, C) = A’B’ + AC.
(b) F(1,3,5,4,7)
On Mapping the given function in a Karnaugh map, we will see
1 Pair and 1 Quad
Pair is m4 + m5
Quad is m1 + m3 + m5 + m7
= A’B’C + A’BC + AB’C + ABC + AB’C’ + AB’C
= A’C(B’ + B) + AC(B’ + B) + AB’(C’ + C)
(B +B' ) = 1 , (C’ + C) = 1
= A’C + AC + AB’
= C(A’ + A) + AB’
= C + AB’
Therefore the simplified Boolean expression for the given data is
F(A, B, C) = C + AB’.
(c) m0+m2+m4+m6.
On Mapping the given function in a Karnaugh map, we will see
2 Pairs
Pair-1 is m0 + m4
Pair-2 is m2 + m6
= A’B’C’ + AB’C’ + A’BC’ + ABC’ = B’C’(A’ + A) + BC’(A’ + A)
= B’C’ + BC’
= C’(B’ + B)
= C’
Therefore the simplified Boolean expression for the given data is
F(A, B, C) = C’.
(d) (0,2,4,6)
It will have the same expression as that of Option (c)

Nick walked 5 miles to reach his aunt's house. From there he traveled 8 miles to the shopping mall on a bicycle. He traveled 80% faster on the bicycle than on foot. Let r represent his rate of walking in miles per hour. Identify the expression that represents the number of hours Nick took to reach the shopping mall in terms of r. Then find the time taken by Nick to reach the shopping mall if he walked at an average speed of 3 miles per hour
Answers
The number of hours Nick took to reach the shopping mall in terms of r is ; 3.14 hours.
What is rate?Rate is a measure of a quantity using another quantity as the basis.
Analysis:
speed travelling on foot = r
distance travelled on foot = 5 miles
time taken = 5/r
speed travelling on bicycle 80 percent faster than on foot is 1.8r
distance travelled on bicycle = 8 miles
time taken = 8/1.8r = 40/9r
total time taken to get to the mall = 5/r + 40/9r = 85/9r
speed while walking = 3 miles per hour = r
time taken = 85/9 x 3 = 3.14 hours
In conclusion, number of hours Nick took to reach the shopping mall in terms of r is 85/9r is 3.14 hours.

The Pythagorean theorem is also known as the Pythagoras' theorem. The height of the triangle is 12cm.
What is Pythagoras theorem?The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between the three sides of a right triangle in Euclidean geometry. The size of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides, according to this rule.
Given a=10cm and b=13cm, therefore, the height of the triangle can be found using the Pythagoras theorem, therefore,
AB² = AD² + BD²
13² = AD² + 5²

Answer:
Step-by-step explanation:
Consider the end points (-7,-1) and (-5,-9)
The center is the mid point between these two points.
The value of center is,
(h,k) = ((-7-5)/2, (-1-9)/2)
(h,k) = (-12/2,-10/2)
(h,k) = (-6, -5)
If the center (h,k) = (-6, -5) and radius is r then the equation of the circle is,
Equation of Circle,
((x-h)^2)+((y-k)^2) = r^2
((x+6)^2)+(y+5)^2 = r^2
Hence, the answer is ((x+6)^2)+(y+5)^2 = r^2.
