Answer:
9
Step-by-step explanation:
The length of the paper , x, can be obtained using Pythagoras :
Width = 12 ; length = 15
x² = 15² - 12²
x² = 225 - 144
x² = 81
x = sqrt(81)
x = 9
Hence, length of the paper = 9 inches
Markup = $4
b) markup as a percentage of cost is 33.3%
Step-by-step explanation:
Markup
markup = selling price - cost
= $13 - 9
... markup = $3
Markup as a Percentage of Cost
To find the percent markup, divide the markup by the reference value and multiply the ratio by 100%. The reference value for markup is usually cost price, but sometimes may be selling price.
... markup / cost × 100% = 3/9×100% = 33 1/3% ≈ 33.3%
Answer:
the corresponding point is (5,-4)
Step-by-step explanation:
x+3=8 <=> x =8-3=5
so f(5+3)=f(8)=-4
so the corresponding point is (5,-4)
The main thing is rise/run. y=mx+b that is the formula for slope
Answer:
D. The expression 5 y plus 2 y is equivalent to 15 y minus 8 y.
Step-by-step explanation:
15y - 8y = 7y
5y + 2y = 7y
This means that they are similar.
