I believe the answer is A :)

The definition of Proportionality in math is

In mathematics, two variables are proportional if there is always a constant ratio between them. The constant is called the coefficient of proportionality or proportionality constant. If one variable is always the product of the other variable and a constant, the two are said to be directly proportional

In AABC, MLA = 53, m4C = 84, and side a = 8 inches. Find the length of side b to the nearest tenth of an inch.

Cerrena [4.2K]

Answer:

6.8 inches

Step-by-step explanation:

Given data :

m∠ A = 53° , m∠ C = 84° , side a = 8 inches

therefor m ∠ B = ( 180 - (84 + 53 )) = 43°

<u>Find the length of side b </u>

we will apply sine rule here

$\frac{a}{sinA} = \frac{b}{sinB} = \frac{c}{sinC}$

= $\frac{8}{sin53}$ = $\frac{b}{sin43}$

∴ b = ( sin43° * 8 ) / sin53°

= ( 0.6819 * 8 ) / 0.7986

= 5.4552 / 0.7986 = 6.83 ≈ 6.8 inches

The question is down below

180 = x + x+2 + x+1

180=3x+3

177= 3x

x = 59

Angle A = 59 +2 = 61 degrees

How much Will be left after

vfiekz [6]

$\bf \textit{Amount for Exponential Decay using Half-Life}\\\\
A=P\left( \frac{1}{2} \right)^{\frac{t}{h}}\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{initial amount}\to &371\\
t=\textit{elapsed time}\to &45\\
h=\textit{half-life}\to &15
\end{cases}
\\\\\\
A=371\left( \frac{1}{2} \right)^{\frac{45}{15}}\implies A=371\left( \frac{1}{2} \right)^3$

and surely you know how much that is.
