1,530 people

Step-by-step explanation:

First do 0.085 times 600 to get 51 (this stands for 51 new ppl per year)

Second Do 51 times 30 to get 1,530

Look at this inequality.<br><br><br>−0.2x+1.2&lt;1.1
WINSTONCH [101]

Answer:

x > 0.5

Step-by-step explanation:

Given

- 0.2x + 1.2 < 1.1 ( subtract 1.2 from both sides )

- 0.2x < - 0.1

Divide both sides by - 0.2, reversing the symbol as a result of dividing by a negative quantity.

x > 0.5

Find the magnitude and direction in degrees of the vector v=6i+2 seq31​
masha68 [24]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the vector

v = 6i + 2√3j

The Magnitude of a vector:

\mathrm{Computing\:the\:Euclidean\:Length\:of\:a\:vector}:\quad \left|\left(x_1\:,\:\:\ldots \:,\:\:x_n\right)\right|=\sqrt{\sum _{i=1}^n\left|x_i\right|^2}

=\sqrt{6^2+\left(2\sqrt{3}\right)^2}

=\sqrt{36+12}

=\sqrt{48}

\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b}

=\sqrt{3}\sqrt{2^4}

=4\sqrt{3}

The Direction of a vector:

tan Ф = y/x

y=2√3

x = 6

tan Ф = y/x

          = 2√3 / 6

           = √3 / 3                  

\theta \:=tan\:^{-1}\left(\frac{\sqrt{3}}{3}\right)

\:\theta \:=\frac{\pi \:}{6}=30^{\circ \:}

WILL GIVE BRAINLIST SOON AS I CAN I DONT UNDERSTAND THIS, PLZ HELP​
allochka39001 [22]

Answer:

b = 7\sqrt{3}

Step-by-step explanation:

Since the triangle is right use the tangent ratio to solve for b

and the exact value

tan30° = \frac{1}{\sqrt{3} }, thus

tan30° = \frac{opposite}{adjacent} = \frac{7}{b} and

\frac{7}{b} = \frac{1}{\sqrt{3} } ( cross- multiply )

b = 7\sqrt{3}

Solve this equation<br> 5x+2=3x-20-1x
Rainbow [258]
5x+2=3x-20-1x\\5x+2=2x-20\ \  \ \ |subtract\ 2\ from\ both\ sides\\5x=2x-22\ \ \ \ |subtract\ 2x\ from\ both\ sides\\3x=-22\ \ \ \ |divide\ both\ sides\ by\ 3\\\\\boxed{x=-\frac{22}{3}}\Rightarrow\boxed{x=-7\frac{1}{3}}
