Answer:
Step-by-step explanation:
Given:
m∠1 = 65°
Since. ∠1 and ∠2 are the angles of linear pair,
m∠1 + m∠2 = 180°
65° + m∠2 = 180°
m∠2 = 115°
m∠1 = m∠3 [Vertical angles]
m∠3 = 115°
Since, ∠1 and ∠4 is the linear pair of angles,
m∠1 + m∠4 = 180°
65° + m∠4 = 180°
m∠4 = 180 - 65 = 115°
m∠4 + m∠5 = 180° [Consecutive interior angles between the parallel lines]
115° + m∠5 = 180°
m∠5 = 180° - 115° = 65°
m∠5 + m∠6 = 180° [Linear pair of angles]
65° + m∠6 = 180°
m∠6 = 115°
m∠5 = m∠7 [Vertical angles]
m∠5 = m∠7 = 65°
m∠6 = m∠8 [Vertical angles]
m∠6 = m∠8 = 115°
Eight less than ten is another way of saying 10-8. So it is saying 2 times a number is 82. This can be represented as 2x=82. Divide both sides by 2 to get x=41. So the "number" is 41.
First, convert the 20% to a real mathematical number. For percents, this is always done by dividing the 20% by 100%, or 20% / 100% = 0.200.
Second, find out what 20% of $600.25 is. This is the amount of the sale discount. This is always found by mulitplying 0.200 by the item's cost $600.25, like this:
0.200 x $600.25 = $120.05.
So for this sale, you'll save $120.05 on this item.
This means, the cost of the item to you is
$600.25 - $120.05 = $480.20.
Alternatively, you can think about it this way. The item is 20% off. This means you'll pay 80.000% of the total cost (100% - 20% = 80.000%).
Now what's 80.000% of the total cost?
0.800 x $600.25 = $480.20.
Just like the result above, the sale price on the item is $480.20.
Hope this helps you on your assignment! :)
