If it was priced at $100 and had 30% off, it would cost
($100 - (30% of $100)) =$70.
If there was an additional 20% off, it would cost
($100 - (30% of $100) - (20% of 30% of $100)) = $56.
So the total savings is (100-56)/100=44%.
For $74.99, the answer is the same but the numbers are slightly different,
(74.99 - (30% of 74.99) - (20% of 30% of 74.99))/74.99 = 44%.
x²-6x =7
First we have get rid of that 7 from the right side and move it to the left side. To move 7 to the left side, we have to subtract 7 from both sides.
x²-6x-7= 7-7
x²-6x-7 = 0
To make this equation a perfect square, first we have to check the x term. Here -6x given. We have to divide the co-efficient of x by 2, and then we have to add the square of it.
The co-efficient of x is -6 here. Dividing it by 2, we will get -6/2 = -3.
We will have to add (-3)² here. (-3)² is 9. So in the place of -7, we have to make 9, to make the equation a perfect square.
9-(-7) = 9+7 = 16
So by adding 16 to the left side, we can make the equation a perfect square.
x²-6x-7+16 =0
x²-6x+9 =0
x²-6x+(-3)² =0
(x-3)² =0
Answer: $142,500
Step-by-step explanation:
From the question, we are informed that Ned borrowed 95% of the value of his house and that the value of the house is $150,000,
The amount that Ned borrowed will be:
= 95% × $150,000
= 95/100 × $150,000
= 0.95 × $150,000
= $142,500
Ned borrowed $142500
Answer:
L = a √( 4 + 2√2)
Step-by-step explanation:
L = a √( 4 + 2√2) is the equation which can be used to calculate the length of each side of the octagon. In the equation i.e. L = a √( 4 + 2√2), in which ''a'' is the length of each side of the octagon. So by putting of ''a'' we get the length of each side of the octagon. The octagon is regular means all of its sides and angles are congruent or similar to each other. Each angle in the octagon has a measure of 135 degrees.
I think the answer is 19.5
