Answer:
A. t > 2.5
Step-by-step explanation:
If she wants to achieve <em>more </em>than 590, we already know the sign would be greater than (>).
All we have to do is divide 590/236, which gives us 2.5.
Therefore, she will have to ride more than 2.5 hours to reach her goal, t > 2.5
Hope this helps :)
Good luck on your test.
Answer:

Step-by-step explanation:
If the perimeter of a circle is d*pi, then you would do ((30*3.14)-(20*3.14))/2 to find the perimeter.
30*3.14=94.2
20*3.14=62.8
94.2-62.8=31.4
31.4/2=15.7 cm
Answer:
Step-by-step explanation:
note :
( a + b )^3 = a^3 +b^3 +3 a²b +3b²a + b^3...(*)
the condition is : r = 1 and p=1
put : x= a and b = 1 in (*) you have :
(x + 1)^3 = x^3 +3x² +3x +1
the zeros is : x = - 1
bcause : x^3 +3x² +3x +1 = 0 .... (x + 1)^3 = 0 so : x = - 1
