Answer:

Step-by-step explanation:

use the below to remember how to use trig functions ( copy this to your computer for use later )

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

We can use TOA to find AC

Tan(31) = Opp / 9

9* Tan(31) = Opp ( Opp = AC)

5.407745571 = AC

How do you write 3 7/10 as a decimal

Leokris [45]

Answer:

3.7

Step-by-step explanation:

To change a fraction to a decimal, just divide the numerator with the denominator. Instead of placing the remainder over the divisor, continue to solve until it is answered (unless it's a repeating decimal.)

Divide 7 with 10:

7/10 = 0.7

Remember that there is a whole number, 3. Add that to the decimal you have gotten:

3 + 0.7 = 3.7

3.7 is your answer.

Answer:

$24.35

Step-by-step explanation:

We will use the compound interest formula provided to solve this problem:

$A=P(1+\frac{r}{n} )^{nt}$

P = initial balance

r = interest rate (decimal)

n = number of times compounded annually

t = time

First, change 1% into a decimal:

1% -> $\frac{1}{100}$ -> 0.01

Since the interest is compounded monthly, we will use 12 for n. Lets plug in the values now:

$A=800(1+\frac{0.01}{12})^{12(3)}$

$A=824.35$

Lastly, subtract A from the principal to get the interest earned:

$824.35 - 800 = 24.35$
