Answer:
15
Step-by-step explanation:
Gregory gained 86 dollars in total and he got this money by first getting 11$ and then 5$ for each question he solved correctly, so our equation is
11+5x=86 (x being the number of questions he answered correctly)
11+5x=86 (subtract 11 from both sides)
5x=75 (divide both sides by 5)
x=15
Gregory answered 15 questions correctly
diameter is 15 meters then radius is 15/2 = 7.5 meters
so the amplitude is 7.5 m and height will oscillate with amplitude 7.5 m above and below the center.
midline of the oscillation will be 7.5 m
the wheel.take 8 minutes to complete revolution then it means the height will oscillate with a period of 8 minutes
Y=mx + b
In this case:
m=slope=5
b=y-intercept=3
y=5x+3
Answer:
b i think

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
