The lengths of the boards are 6 cm and 8 cm.
The boards make a right angle.
Therefore the string connecting the boards is the hypotenuse of a right triangle (shown n the figure).
By the Pythagorean theorem,
c² = 6² + 8² = 100
c = 10 cm
Answer: c = 10 cm

The amount that will be saved yearly oh the utility bills will be $65 each year.
<h3>How to calculate the amount of utility saved</h3>
From the information given, the cost per load on hot wash is given as 71 cents per load and the cost of warm wash is given as 25 cents per load.
Therefore, the yearly cost for hot wash will be:
= 71 cents × 365
= 25915 cents
In this case, she cuts down the amount of laundry that she does in hot water to one-half will be:
= 25915 cents × (3/4 - 1/2)
= $259.15 × 0.25
= $65
In conclusion, the correct option is $65.

Answer:
Step-by-step explanation:
The slope represents how much y is predicted to change on average for each 1 unit in x.
y = appraised value of a house in East Meadow County
x = # of rooms
1 unit of x = 1 additional room
1 unit of y = $1,000
slope = 19.79
Answer: Each additional room in a house in East Meadow County is predicted to increase the appraised value by 19.79 x $1,000 = $19,790, on average.
Note: Since we only sampled homes in East Meadow County, our regression equation is only good to predict appraised values in that county. So, our interpretation must include that fact.
