Answer:

$\large\boxed{d_1=\dfrac{2A}{d_2};\ d_2=\dfrac{2A}{d_1}}$

Step-by-step explanation:

$A=\dfrac{1}{2}d_1d_2\qquad\text{multiply both sides by 2}\\\\2A=2\!\!\!\!\diagup\cdot\dfrac{1}{2\!\!\!\!\diagup}d_1d_2\\\\2A=d_1d_2\to d_1d_2=2A$

$\text{For}\ d_1:\\\\d_1d_2=2A\qquad\text{divide both sides by}\ d_2\neq0\\\\d_1=\dfrac{2A}{d_2}\\\\\text{For}\ d_2:\\\\d_1d_2=2A\qquad\text{divide both sides by}\ d_1\neq0\\\\d_2=\dfrac{2A}{d_1}$

Kyle plays softball. His goal is to have a batting average of .400 or greater by the end of the season. The ratio that relates t

gregori [183]

Answer:

The number of hits is $T \ge 30 \ hits$

Step-by-step explanation:

From the question we are told that

The ratio of the number of hits to the number of chances is equivalent to the batting average

The number of chances is j = 65 + 10 = 75

The number of hit so far is n = 25

Generally the batting average can be represented mathematically as

$A = \frac{n + k}{ j}$

Here k is the number of additional hits Kyle need to get in order to obtain the batting average of 0.40 or more

$\frac{25 + k}{ 75} \ge 0.40$

=> $k \ge 5 \ hits$

Hence the number of hits for Kyle to get a batting average of 0.400 or greater by the end of the season is

$T \ge k + n$

=> $T \ge 5 + 30$

=> $T \ge 30 \ hits$
