题目
The ratio of 16 to g is equal to ratio of g to 49
选项
C.The two quantities are equal.
D.The relationship cannot be determined from the information given.
解析
根据题意可得到等式\(\frac{16}{g}=\frac{g}{49}\),通过交叉相乘可得\(g^{2}=16\times49\),即\(g^{2} = 784\),解得\(g=\pm28\)
- 当\(g = 28\)时,\(A\)量(\(g\))和\(B\)量(\(28\))相等
- 当\(g=-28\)时,\(A\)量(\(g=-28\))小于\(B\)量(\(28\))
由于\(g\)的值有两种可能,所以无法根据所给信息确定\(A\)量和\(B\)量的大小关系,答案为\(D\)
