Answer:
Adam plans to choose a video game from a section of the store where everything is 75 % off .
He writes the expression
Where d is the original price is d dollars.
75% off on d is represented as 0.75d.
And 0.75d is subtracted from original price d to get the price after discount. Hence, the equation forms
For example:
Let the price of an item be = $100
So, price will be = dollars
---------------------------------------------------------------------------------------
Rena correctly writes another expression,
This means that 25% of d will be charged.
This is also correct.
Same example as above.
Let the price be = $100
Price will be = dollars

Given triangle KLM with two sides given as 45 yd and 20 yd and a 25 degree angle opposite the 20 yd side.
We find the angle made at the opposite of the 45 yd side using the sine rule as follows.
Thus, the third angle is given by 180 - 25 - 71.97 = 83.03 degrees.
We also use the sine rule to find the third side of the triangle as follows.
Therefore, amount of fencing needed to surround the perimeter of the picnic area = 45 + 20 + 46.97 = 111.97 ≈ 120 yds
