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
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:
3/28Step-by-step explanation:
Total number of cartons:
2 + 3 + 3 = 8Let cm be the chocolate milk, there are 3 cartons of cm.
The probability of the first pull of cm is:
P(cm) = 3/8Then we have 7 total left and 2 cm.
The probability of the second cm is:
P(cm) = 2/7Now the probability of the two pulls:
P(cm and cm) = 3/8*2/7 = 3/28When using substitution to solve this system of equations
6y + 2x = 3
2x + y = 8

Your class wants to raise more than $350 for the Freshman Party and you choose to sell candy and cookies to accomplish this task. You earn $6 on each basket of candy, b, and $3 on each box of cookies, c, that you sell. If the number of boxes of cookies sold is 78, at least how many baskets of candy will you need to sell to reach your goal?
Answers
Answer:
16 baskets of candy.
Step-by-step explanation:
78 boxes of cookies times $3 per box equals $234.
$350-$234=$116 left you need to make so-
each basket of candy earns $6, divide $116 by $6 to equal 56.
You will need to sell 56 baskets of candy at $6 each to reach your goal of $350 .

Answer:
91 feetStep-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)Algebra 1 Chapter 5 test
