Let x = software program
Let y = video game
x < 200 ; y < 300
x + y < 425
50x ; 35y
x = 200 ; y = 225
50(200) + 35(225) = 10,000 + 7,875 = 17,875
x = 125 ; y = 300
50(125) + 35(300) = 6,250 + 10,500 = 16,750
x = 175 ; y = 250
50(175) + 35(250) = 8,750 + 8,750 = 17,500
It is more profitable to maximize production of software program when working within the limits provided.
P(no girls in five births) = p(five boys) = (1/2)^5 = 1/32 = 0.0313

Answer:
Option E.
Step-by-step explanation:
Let the intended length of Rebecca's swimming is = x units
and we assume the length of the pool = l units
Now it is given in the question that " She covers one fifth of her intended distance "
That means distance covered = ![\frac{x}{5}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B5%7D)
" After swimming six more lengths of the pool she had covered one quarter of her intended distance"
So ![\frac{x}{5}+6(l)=\frac{x}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B5%7D%2B6%28l%29%3D%5Cfrac%7Bx%7D%7B4%7D)
![6l=\frac{x}{4}-\frac{x}{5}](https://tex.z-dn.net/?f=6l%3D%5Cfrac%7Bx%7D%7B4%7D-%5Cfrac%7Bx%7D%7B5%7D)
![6l=\frac{x}{20}](https://tex.z-dn.net/?f=6l%3D%5Cfrac%7Bx%7D%7B20%7D)
x = 20×(6l)
x = 120l
Therefore, Rebecca has to complete 120 lengths of the pool.
Option E is the answer.
The answer is A=lw
A=(5)(7)
A= 35 ^meters
