Answer:233.333%
Step-by-step explanation:
1. 10-3=7 subtract end by start
2.7/3=2.333 divide difference by absolute value of start
32.333x100=233.333% multiply by 100 if negative its decreasing if positive it increasing

Yeah, these are tough.
When the plane is flying in the same direction as the wind,
the wind helps it cover ground faster.
Plane + Wind = 460 mph
When the plane is flying opposite to the wind, the wind makes it
cover ground slower.
Plane - Wind = 400 mph
================================
OK. So far we have
Plane + Wind = 460 mph
Plane - Wind = 400 mph
Add the two equations, and you get
2 Plane + zero = 860 mph
Divide each side by 2: Plane = 430 mph
Plug that into the first equation: 430mph + Wind = 460 mph
Subtract 430 mph from each side: Wind = 30 mph
The sales tax can be found through multiplying the total by the decimal form of the given sales tax (7.5=0.075). This operation yields 40.5 or $40.50. I really hope this helps!:)
The value of x is 8√2.
<u>Step-by-step explanation</u>:
<u>From the right triangle,</u>
- The angles are 90°, 45° and the third angle is unknown.
- Third angle = 180° - (90°+45°) = 45°
- The measure of third angle is 45°
The length of the side opposite to angle 45° is a=8.
Therefore, the value of y opposite to angle 45° is also 8.(b=8)
<u>Using Pythagorean theorem,</u>
The length of hypotenuse is c ⇒ c² = a²+b²
c² = 8²+8²
c² = 64+64 = 128
c = √128
c = √64
2
c = 8√2
