You have 10 batteries 3/10 are dead there are only 7/10 batteries that are good. So the expected number of good batteries you could get is 7.
Answer:
175 ft
Step-by-step explanation:
So because these triangles are similar, you can use ratios to find the distances. For the smaller triangle, 100/700 is a 1 to 7 ratio. From that, because it's the longer side, you can divide 1225 by 7 to find d, which is 175 ft.
Answer:
when this quadratic is equal to 0
3(3x^2+13x+14)=0
3(3x+7)(x+2)=0
3 is not equal to 0
therefore (3x+7) or(x+2)=0
