So than this is a triangle so we know that the sum of measure of angles of a triangle is equal 180 degrees
- in this case m<O = 180 -(137+22) = 180 -159 = 21
m<O = 21 degrees
Answer:
1)461,58sm²
2)53,38sm²
Step-by-step explanation:
p=3,14
1) r=14sm
p×r²=14²×3,14=615,44
S1=615,44
r=7sm
p×r²=7²×3,14=153,86
S2=153,86
The painted surface of the circle:
S1-S2=615,44-153,86=
461,58
2) r=9sm
p×r²=9²×3,14=254,34
S1=254,34
r=8sm
p×r²=8²×3,14=200,96
S2=200,96
The painted surface of the circle:
S1-S2=254,34-200,96=53,38
Answer:
1)461,58sm²
2)53,38sm²
Answer:
$42
Step-by-step explanation:
Assuming tax is 10% that would be $7 + $35 = $42
Primarily, horizontal lines mean zero slope. Therefore the equation is y= 3 because you are only left with the y-intercept at this point. The rate of change is another way of saying slope. Function 2's slope is 5 and function 1's slope is 0. Therefore, the rate of change of function 2 is greater than the rate of change of function 1 by 5.
5 is the answer.
hope this helps :)
