B. 30% is the better deal
Explanation:
30% —> .3
.3x12=3.6
3.6>2.0
2x-2>-12
2x>-10
x>-5
hope this helps!
Answer:
18
Step-by-step explanation:
If TP = 7, then TO can be 7 or 11 to make the triangle isosceles.
If TP = 5, then TO can 5 or 11
Stop right there, though! Your logic is correct, but TO cannot be 5! Why? Triangles have certain properties that they must adhere to for a triangle to exist. One such theorem is called the triangle inequality theorem. It states that the sum of the lengths of two different sides is greater than the remaining third side.
The other side length possibilities adhere to this restriction, thankfully. Now, add 7 and 11. 7+11=18
Answer:
B. 140π units²
Step-by-step explanation:
Surface area of a cylinder:
2πrh + 2πr²
2π(5)(9) + 2π(5²)
90π + 50π
140π
it is the same denominator therefore only the numerators are added and the sign is maintained. The answer is -12/9 but it can be reduced to -4/3.
