There's a relatively easy way to solve problems of this nature. You determine the contribution made if the only contributor is the one that contributes the least.
A chicken has the least number of feet, so 24 chickens will contribute 48 feet.
Now, you consider the change in contribution made by substituting a larger contributor. Each pig that replaces a chicken will add 2 feet to the total.
Consider how many feet need to be added, and thus how many larger contributors are needed. 80 -48 = 32 feet need to be added, so 32/2 = 16 of the animals need to be pigs.
There are 16 pigs and 8 chickens.
ST = 2TW since W is the midpoint of ST. So:-
8x + 10 = 2(6x - 7)
8x + 10 = 12x - 14
24 = 4x
x = 6
Therefore SW = ST = 58 and TW = 29
Answer:
x = 2
Step-by-step explanation:
From the data, we obtain the slope :
-1, 8 ; 3, - 4
Slope = Rise / run
Rise = y2 - y1 = (-4 - 8) = - 12
Run = x2 - x1 = (3 - (-1)) = 4
Slope, m = - 12 / 4 = - 3
Recall:
Equation of line :
y - y1 = m(x - x1)
y - 8 = - 3(x + 1)
y - 8 = - 3x - 3
y = - 3x - 3 + 8
y = - 3x + 5
Substituting y = - 3x + 5 into the equation 2x+4y= 0
2x + 4(-3x + 5) = 0
2x - 12x + 20 = 0
-10x = - 20
x = 2
Option B: isosceles
Option D: right
Solution:
Given data:
Three sides of the triangle are 5 cm, 7.1 cm and 5 cm.
If any two sides of a triangle are equal in length, then the triangle is called
an isosceles triangle.
Here, one side = 5 cm and the another side = 5 cm
Therefore the given triangle is isosceles.
If any one of the angle is 90°, then the triangle is right angled triangle.
Here "L" symbol represents the angle is 90°.
Therefore the given triangle is right angled triangle.
Option B and Option D are correct answer.
Hence the triangle is isosceles and right triangle.
