If anyone is good at right triangle trig word problems please help

Answers

Answer:

The height of the hill is 131ft

See explanation in the photo

Answer:

91 feet

Step-by-step explanation:

Refer to attached picture

Let the base is b and the height of the hill is x.

For the smaller triangle we have:

x/b = tan 39.3°

And for the bigger triangle:

(x + 40)/b = tan 49.7°

Solve both equations for b:

b = x/ tan 39.3°b = (x + 40)/tan 49.7°

Eliminate b and get the values of tan, solve for x:

x/ tan 39.3° = (x + 40) / tan 49.7°x tan 49.7° = (x + 40) tan 39.3°x( 1.179) = x(0.819) + 40(0.819)x(1.179 - 0.819) = 32.76x = 32.76/0.36x = 91 feet (rounded to the nearest foot)

You have $500 in a savings account. How long will it take to double that
amount at an 8% annual interest rate?

Answers

Answer:

Step-by-step explanation:

The formula for compound annual interest is  A = P(1 + r)t  where  

A = Accumulated or final amount  (double $500 = $1000)  

P = Principal or original amount  ($500)  

r = Rate as a decimal (0.08)

t = Time in years  

1000 = 500(1 + 0.08)t

2 = 1.08t  

Take the logarithm of both sides.  I prefer the natural logarithm ln, but if you're more comfortable with base 10 logs they will work just as well  

ln(2) = ln(1.08t)  

ln(2) = t*ln(1.08)

t = ln(2)/ln(1.08)

t = 9.0065 years  

Check:  500*1.089.0065 = $1000

Step-by-step explanation:

The compounds that are found on the left of a chemical reaction (the side with the arrow's tail) are the reactants. Therefore our reactants are Iron(III) oxide and Carbon monoxide.

The compounds found on the right-hand side of a chemical reaction/after the arrow are the products. Therefore our products are Iron and Carbon dioxide.

A basket contains 2 cartons of white milk, 3 cartons of chocolate milk, and 3 cartons of strawberry milk. A carton of milk is pulled out of the carton without replacement. Then another carton of milk is pulled out without replacement. What is the probability of pulling out 1 carton of chocolate milk followed by another carton of chocolate milk?

Answers

Answer: 3/8.

Step-by-step explanation: You have to write a fraction with the amounts of milk in the denominator and the amount of chocolate in the numerator.

Answer:

3/28

Step-by-step explanation:

Total number of cartons:

2 + 3 + 3 = 8

Let cm be the chocolate milk, there are 3 cartons of cm.

The probability of the first pull of cm is:

P(cm) = 3/8

Then we have 7 total left and 2 cm.

The probability of the second cm is:

P(cm) = 2/7

Now the probability of the two pulls:

P(cm and cm) = 3/8*2/7 = 3/28
