Answer:
30.
Step-by-step explanation:
The total degree of a triangle is 180.
They give you 60.
The center line coming down creates a 90 degree angle.
So 60+90=150.
180-150=30.
So the top angle is 30 degrees on both sides.
Answer:
54
Step-by-step explanation:
3x3= 9x6= 54
Answer:
We conclude that the constant of proportionality between the number of shirts and how much they cost is:
k = 8
Hence, option 'D' is correct.
Step-by-step explanation:
We know that when 'y' varies directly with 'x', we get
y ∝ x
y = kx
k = y/x
where k is called the constant of proportionality
Given the points
For (10, 80)
substituting y = 80 and x = 10 in the equation
k = y/x
k = 80/10 = 8
For (20, 160)
k = y/x
k = 160/20 = 8
For (50, 400)
k = y/x
k = 400/50 = 8
It is clear that the value of k is the same for all the points.
Thus, the value of k = 8
Therefore, we conclude that the constant of proportionality between the number of shirts and how much they cost is:
k = 8
Hence, option 'D' is correct.
Answer:
8/9
Step-by-step explanation:
8/9 has a repeating decimal of 8. No matter how many times you divide it, you will get the answer 0.8888 and to infinty.
Perimeter is adding up all the dues together
if it’s 30
13+5=18
30-18=12
x is 12
