1,4,3 are parallelogram and the the second one is not necessarily a parallelogram
Answer:
8/5=x
Step-by-step explanation:
1/2x+12=8x
Subtract 1/2x from both sides
12=15/2x
Multiply 2/15 on both sides
8/5=x
Simple, first find a common denominator, 24.
So,
7/4*6= 42/24
and
5/6*6=30/24
Then just add,
42/24
+
30/24
Making it 72/24.
72/24=3
Thus, your answer is, 3.

Answer:
- square root of 5 is approximately 1 less than square root of 10
- square root of 10 is between 3.1 and 3.2
- square root of 10 is less than 3.5
Step-by-step explanation:
√5 and √10 are plotted on the number line shown below.
Rounded to 1 decimal place, √5 ≈ 2.2 and √10 ≈ 3.2, so it could be said they differ by about 1 unit. The above answer choices are the ones that match the graph.
Answer:
4500
or 4712.39
What we need to know: The formula for the volume of a cone is: 
So we are solving for V
Step-by-step explanation:
1) Radius is half of diameter r=30/2 thus, your radius is 15
2) you then have all your variables so you can start plugging values into your equation:
r=15 h=60

This would be your exact answer but if you are solving for a rounded answer it would be
V~4712.39
