Answer:
153.94
Step-by-step explanation:
The formula for area is pi*radius^2
the radius is 7, so we do pi7^2 which is 49pi
49pi is 153.93804 which is 153.94 rounded to two decimal places
Answer: 9
Step-by-step explanation:
3-2x-3
2x-3=-6
3--6=3+6=9
Answer:
100
Step-by-step explanation:
since its collinear it has to be 180 -80 which equals 100.
Answer:
<h2>y = 31</h2>
Step-by-step explanation:
We know: opposite angles in a parallelogram have the same measure.
Therefore we have the equation:
<em>subtract y from both sides</em>

We know: the sum of the angle measures in the triangle is 180°.
Therefore we have the equation:
<em>subtitute x = 87</em>

<em>subtract 149 from both sides</em>

Answer:
correct answer is option B
Step-by-step explanation:
as we know equation of line
y = m x + c....................(1)
where c is the intercept
m is the slope
m = 
m = 
m = 35
putting value of m in equation (1)
we get
y = 35 x + c
from the graph we can clearly see that line is passing through (0,0) hence
0 = 35 (0)x + c
c = 0
hence the equation of line comes out to be
y = 35 x
correct answer is option B
