If the area of a rectangle is 10in^2, the length (2+sqrt(2))in. What is the width?
pychu [463]
Area=length times width
area=10
length=2+√2
width=w

10=(2+√2)(w)
divide both sides by (2+√2)
\frac{10}{2+ \sqrt{2} } =w
if we were to rationalize the dnomenator
multiply by\frac{2- \sqrt{2} }{2- \sqrt{2} }
\frac{10(2- \sqrt{2})}{4-2 } =w
\frac{20- 10\sqrt{2}}{2} =w
10- 5\sqrt{2} =w

the width is 10-5√2 m

german
27 in the first group, 36 in the second. Here's the work: Divide 63 by 7 (3 parts plus 4 parts) equals 9. Multiply 9 by 3 for the first group and you get 27, multiply 9 by 4 for the second group to get 36.

A plane is approaching an aircraft carrier at 25° angle of elevation from 3.2 miles away how far above sea level is the plane
s2008m [1.1K]

Answer:

Height\approx 1.35\ miles

Step-by-step explanation:

The angle of elevation=25\textdegree

It is 3.2\ miles away from the point.

If we imagine a right  triangle having an angle 25\textdegree.

Hypotenuse=3.2, Opposite=Height from sea level(h)

\sin 25=\frac{opposite}{hypotenuse}\\\\\sin 25=\frac{h}{3.2}\\\\h=3.2\times \sin 25\\\\h=3.2\times 0.4226\\\\h=1.3524\approx 1.35\ miles
