Equality Properties

Step-by-step explanation:

Step 1: Define Equation

186 = 6(3n + 7)

Step 2: Solve for n

Divide 6 on both sides: 31 = 3n + 7
Isolate n term: 24 = 3n
Isolate n: 8 = n
Rewrite: n = 8

Step 3: Check

Plug in n into the original equation to verify it's a solution.

Substitute in n: 186 = 6(3(8) + 7)
Multiply: 186 = 6(24 + 7)
Add: 186 = 6(31)
Multiply: 186 = 186

Here we see that 186 does indeed equal 186.

∴ n = 8 is the solution to the equation.

Suppose you invest 1600 at annual interest rate of 7.9% compounded cont how much will u have after 10yrs

frez [133]

Answer:

B. $3525.43

Step-by-step explanation:

We will use continuously compound interest formula to solve our problem.

$A=P*e^{rT}$

A= Amount after T years.

P= Principal amount.

r= Interest rate (in decimal form).

e= The mathematical constant e.

T= Time in years.

First of all we will convert our interest rate in decimal form.

$7.9\text{ Percent}=\frac{7.9}{100}=0.079$

Now let us substitute our given values in above formula.

$A=1600*e^{0.079*10}$

$A=1600*e^{0.79}$

$A=1600*2.2033964262559365$

$A=3525.4342820094984\approx 3525.43$

Therefore, we will get an amount of $3525.43 after 10 years and option B is the correct choice.

UHHHHH IM GONNA FAIL MATH YALL Just answer it ig-? I WILL MARK AS BRAINLIEST

tankabanditka [31]

Answer:

30.96 m^2

Step-by-step explanation:

Side length of the square is also the diameter of the semicircle so:

r = 0.5 * 12 m = 6 m

Since you want the area of the shaded area, you have to subtract the area of both semi circles from the area of the square:

Square Area - Semi Circle Area - Semi Circle Area = Shaded Region Area

(12 m * 12 m) - (0.5 * 3.14 * 6^2 m) - (0.5 * 3.14 * 6^2 m)

= 144 - 56.52 - 56.52

= 30.96 m^2
