What is the value of the expression 3.9 times 10^5 /1.3 times 10^2
elena-s [515]
\bf ~~~~~~~~~~~~\textit{negative exponents}
\\\\
a^{-n} \implies \cfrac{1}{a^n}
\qquad \qquad
\cfrac{1}{a^n}\implies a^{-n}
\qquad \qquad 
a^n\implies \cfrac{1}{a^{-n}}
\\\\
-------------------------------\\\\
\cfrac{3.9\times 10^5}{1.3\times 10^2}\implies \cfrac{3.9}{1.3}\times \cfrac{10^5}{10^2}\implies 3\times 10^5\cdot 10^{-2}\implies 3\times 10^{5-2}
\\\\\\
3\times 10^3\implies 3.0\times 10^3

∠LMN and ∠PQR are complementary angles. Find m∠LMN if m∠LMN = (4x-2) and m∠PQR= (9X+1)
kow [346]

Answer:

<h2>m∠LMN = 26°</h2>

Step-by-step explanation:

Since ∠LMN and ∠PQR are complementary it means that the sum of their angles is 90°

To find m∠LMN , add both m∠LMN and m∠PQR and equate it to 90 to find x then substitute the value of x into the expression for m∠LMN

That's

m∠LMN + m∠PQR = 90

4x - 2 + 9x + 1 = 90

13x - 1 = 90

13x = 90 + 1

13x = 91

Divide both sides by 13

x = 7

From the question

m∠LMN = (4x-2)

m∠LMN = 4(7) - 2 = 28 - 2

We have the final answer as

<h3>m∠LMN = 26°</h3>

Hope this helps you

Find the length of the missing side of the right triangle. 19 a 15.2​
diamong [38]

The length of the missing side of the triangle is 129.96

<h3>Right angle triangle</h3>

Right angle triangle are triangle that has one of its sides as 90 degrees. The sides can be found using Pythagoras theorem. Therefore,

c² = a² + b²

where

c = hypotenuse

a and b are the other legs.

Therefore,

19² - 15.2² = a²

a = 361 - 231.04

a = 129.96
