Answer:
parallel is 5x + 3y = 13
perpendicular is 6x - 10y = 7
Step-by-step explanation:
To solve this problem, we can use cross multiplication:
First, we can to convert inches into feet so...
5 inches = 0.416667 ft
7 inches = 0.583333 ft
(0.416667 ft/ 0.583333 ft) = (12 ft/ x ft)
x = 16.8 ft
So the actual width is 16.8 ft.
Hope this helps!
Answer:
The expression for the given discount on item is 74 - [0.4 × 74 + 1.07 × 74]
Step-by-step explanation:
Given as :
The market price of item = m.p = $74
The discount percentage on item = 40%
The sale tax added = 7%
The selling price = s.p = $74 + 7% of $74
I.e s.p = 1.07 × 74
<u>Now, from discount </u>
d % = 
Or, 40% =
Or, 0.4 = 1 - 
Or, 0.4 × 74 = ( 74 ) - (1.07 × 74)
Or, 74 - (1.07 × 74) - 0.4 × 74 = 0
Or, 74 - 74 (1.07 + 0.4) = 0
Or, 74 - [0.4 × 74 + 1.07 × 74] = 0
Hence, The expression for the given discount on item is 74 - [0.4 × 74 + 1.07 × 74] . Answer
Umm I would say I know but honestly I don’t so 1247x1737x-wish
Ok so defenitions
isosceles means 2 angles or sides are equal legnth
scaleen means no sides or angles are eaqual measure
equilateral means all sides and angles are equal measure
(since all side equal measure, all angles are always 60)
acute means all angles are less than 90
obtuse means at least one angle is more than 90
right means that 1 angle is 90 degrees
ok so
isosceleese
for it to be acute, maybe make the angles 50,50,80
obtuse 40,40,100
right 90,45,45
scaleene
acute, 30,70,80
obtuse 100,30,50
right, 90,40,50
equilateral all angles are automatically equal to 60 so
acute: 60,60,60
obtuse: not possible
right: not possible
