97/6 = 16 1/6
Answer:
Step-by-step explanation:
Given two congruent, isosceles triangles are joined, as shown, to form a parallelogram, the largest angle of the parallelogram is 116 degrees. Write two equations. Write them find the value of a and the value of b.
We know that the sum of all the internal angles is 360 degree. So the equation will be
4 a + 2b = 360
According to the question the largest internal angle of the parallelogram is 116 degree. So a + b = 116
Now we have the two equations as
4a + 2b = 360
a + b = 116
Multiply the second equation by 4 we get
4a + 2b = 360
4a + 4b = 464
Or – 2b = - 104
Or b = 52
Now a + b = 116
Or a + 52 = 116
Or a = 116 – 52
Or a = 64
Therefore the values of a and b are 64 and 52 degrees

Answer : 5
The number of minutes it will take 5 machines to make 15 widgets is 90 minutes
Given that :
The time taken to make a widget is directly proportional to the number of widgets made and inversely proportional to the number of machines utilized.
Using the variation protocol defined :
Let :
n = number of widgets made
n = number of widgets made m = number of machines used
n = number of widgets made m = number of machines used t = time taken
Hence, from joint variation :
t α n α 1/m
t = kn/m
Where k = constant of proportionality :
Solving for k
When t = 10, n = 5, m = 15
10 = (k × 5) / 15
15 × 10 = 5k
150 = 5k
k = 150 / 5
k = 30
Equation becomes :
t = 30n/m
Solve for t ;
When m = 5 ; n = 15
t = (30 × 15) / 5
5t = 450
t = 450 / 5
t = 90
Hence, it will take 90 minutes.
