Answer:
640
Step-by-step explanation:
price ÷ 1 - percent (as decimal)
179.20÷(1-0.72) = 640
Answer:
-6(3x +2) = 2x -5 -20x -7 (use the distributive property )
-18x -12 = -18x - 12 (i combined like terms on the right side of the equation)
at this point I can tell that it's true for any value of x, so they all apply
Step-by-step explanation:
1) Identify the statement you want to prove is true
2) Assume temporarily that the statement is false; assume the opposite is true
3) Obtain statements that logically follow from your assumption.
4) Reason logically until you reach a contradiction of a known fact.
5) Point out that your assumption must be false, and the statement must then be true.
For the 2nd question......is it correct????? Because the area of square is s.s and area of rectangle is l.b
The picture in the attached figure
Let
h-------> <span>the planes height above ground level at the time of the bird strike
</span>
we know that
sin 7.7°=opposite side angle 7.7°/hypotenuse
where
opposite side angle 7.7°=h
hypotenuse=4 miles
so
sin 7.7°=h/4-------> h=4*sin 7.7°-----> h=0.54 miles
1 mile-----------> 5280 ft
0.54 mile------> x
x=0.54*5280-----> x=2829.79 ft------> 2830 ft
the answer is2830 ft
