Answer:

Hello,

Answer 3.1

Step-by-step explanation:

Let's calculate the square of each positive number

since a <b <==> a² < b²

$(\sqrt{10}) ^2=10\\\\3.1^2=9,61\\|10-9.61|=0,39\\4.3^2=18,49\\|10-18.49|=8,49\\3.6^2=12,96\\|10-12.96|=2,96\\\\2.8^2=7,84\\|10-7.84|=2,16\\\\0.39 < 2.16 < 2.96$

Rhombus ADEF is inscribed into a triangle ABC so that they share angle A and the vertex E lies on the side BC . What is the leng

Thepotemich [5.8K]

Answer:

Length of side of rhombus is $x=\frac{ab}{a+b}$

Step-by-step explanation:

Given Rhombus ADEF is inscribed into a triangle ABC so that they share angle A and the vertex E lies on the side BC. We have to find the length of side of rhombus.

It is also given that AB=a and AC=b

Let side of rhombus is x.

In ΔCEF and ΔCBA

∠CEF=∠CBA (∵Corresponding angles)

∠CFE=∠CAB (∵Corresponding angles)

By AA similarity rule, ΔCEF~ΔCBA

∴ their sides are in proportion

$\frac{EF}{AB}=\frac{CF}{AC}$

⇒ $\frac{x}{a}=\frac{b-x}{b}$

⇒ $xb=ab-ax$

⇒ $x(a+b)=ab$

⇒ $x=\frac{ab}{a+b}$

Hence, length of side of rhombus is $x=\frac{ab}{a+b}$

If you traveled in space at a speed of 1000 miles per hour, how far would you travel in 7.5 x 10^5 hours? Write your answer in s

Lynna [10]

Basically, every zero a number has to the end, the higher the scientific notation will be. Because 1000 has three zeroes, 10^5 will go to 10^8. So, you will travel 7.5 x 10^8 miles.
