You invest 300$ at 4% intrest compounded every year what will your balance be after 5 years?
frutty [35]

Answer:

Option D \$365.00  

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=5\ years\\ P=\$300\\ r=0.04\\n=1  

substitute in the formula above  

A=300(1+\frac{0.04}{1})^{1*5}  

A=300(1.04)^{5}  

A=\$365.00

What is the missing angle
noname [10]

Answer ☘️

★ Important points to know

{\boxed{ \bold{Exterior  \: Angle  \: Theorem :  - }}}

  • The exterior angle of a triangle is equal to the sum of the two opposite interior angles.
  • \pink{  ↪ \sf \angle \: C +  \angle  \: D =  \angle \: B}

★ Let's solve :-

\sf ↪\angle \: 65 \degree +  \angle \: 30 \degree =\angle \:B\\  \\  \sf ↪\angle \: 95 \degree =  \angle \:B

Hence option A 95⁰ is the right ans ✓

  • All angles in a triangle add up to 180°

Step-by-step explanation:

<u>Step 1: Set Up Equation</u>

40° + (y + 30)° + y° = 180°

<u>Step 2: Solve for </u><em><u>y</u></em>

  1. Combine like terms:                    2y° + 70° = 180°
  2. Isolate <em>y</em> term:                              2y° = 110°
  3. Isolate <em>y</em>:                                       y° = 55°
