Answer:
Step-by-step explanation:
Δx = 10-(-6) = 16
Δy = -3-11 = -14
(-6+16/3, 11-14/3) = (-⅔, 6⅓)
(10-16/3, -3+14/3) = (4⅔, 1⅔)
It’s a rational number when you round it to any place value, if you don’t round, it’s not rational.
Rational numbers are fractions and decimals that don’t go on and on forever, and no fractions that are over 0.
Since .3333 doesn’t go on forever, it’s rational.
It’s rounded to the Ten Thousandths.
Examples:
Rational: 4/5 .35 6/8
Not Rational: .3333333 (forever) 4/0 6/0 .555555 (forever).
Hope this helps :)
First we need to calculate the selling price after 50% increase
selling price = original cost + increase
selling price = 100% original cost + 50% original cost
selling price = 150% original cost
selling price = 1.5 × original cost
selling price = 1.5 × 30
selling price = 45
The selling price after getting a markup is $45
Second, we need to calculate the sale price after markdown 50%
Right now, we use $45 as the original price not $30 to count the sale price
sale price = original price - markdown
sale price = 45 - 50% × 45
sale price = 45 - 0.5 × 45
sale price = 45 - 22.5
sale price = 22.5
The sale price is not $30
Answer:
RHS
Step-by-step explanation:
It is given that XY is the perpendicular bisector of WZ. This means that it forms 90-degree angles at Y. (angle XYZ and angle XYW are 90 degrees). (R)
Since there is a right angle at Y, XZ and XW are the hypotenuses. (H)
There is a common line between triangle XYZ and XYW and that is XY. (S)
Therefore you can prove ΔXYZ ≅ΔXYW because of RHS
