Answer:
А.The system has two solutions, but only one is viable because the other results in a negative width.
Step-by-step explanation:
Given
Let:
length of play area A
width of play area A
length of play area B
width of play area B
Area of A
Area of B
From the question, we have the following:




The area of A is:

This gives:

Open bracket

The area of B is:


Substitute: 

Open brackets


Expand


We have that:

This gives:

Collect like terms


Using quadratic calculator, we have:
or
--- approximated
But the width can not be negative; So:

Answer:
3 pints = 6 cups
Step-by-step explanation:
Formula: multiply the volume value by 2
Answer:
4 feet of distance between each other it is very simple and easy.
Step-by-step explanation:

Answer: in 95% of races, his finishing time will be between 62 and 64 seconds.
Step-by-step explanation:
The empirical rule states that for a normal distribution, nearly all of the data will fall within three standard deviations of the mean . The empirical rule is further illustrated below
68% of data falls within the first standard deviation from the mean.
95% fall within two standard deviations.
99.7% fall within three standard deviations.
From the information given, the mean is 63 seconds and the standard deviation is 5 seconds.
2 standard deviations = 2 × 0.5 = 1
63 - 1 = 62 seconds
63 + 1 = 64 seconds
Therefore, in 95% of races, his finishing time will be between 62 and 64 seconds.
Answer:
<h2> 6/35</h2>
Step-by-step explanation:
This problem is on fraction
given data
chocolate chip cookies= 12
lemon cookies = 6
strawberry cookies= 17
the total cookies is = 12+6+17
=35 cookies
Therefore the fraction that indicates the lemon cookies is
=the number of lemon cookies/total cookies
=6/35
Hence the fraction lemon is 6/35
