To solve this problem, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
where:
A = final amount
P = principal (initial amount)
r = annual interest rate (as a decimal)
n = number of times the interest is compounded per year
t = time (in years)
In this case:
P = $11,000
r = 2.5% = 0.025 (since it's compounded monthly, we need to divide by 12 to get the monthly rate)
n = 12 (compounded monthly)
t = 21 years
Plugging in these values, we get:
A = 11000(1 + 0.025/12)^(12*21)
A ≈ $16,180.64
Therefore, the value of the account at the child's twenty-first birthday will be approximately $16,181.
The regular price of a color TV is $445.81. During a sale, Hill TV is selling the TV for $393.36. Determine the percent decrease in the price of the TV.
The regular price of the TV is $445.81, and the sale price is $393.36.
To find the percent decrease in the price, we can use the formula:
percent decrease = (original price - sale price) / original price x 100%
Substituting the given values, we get:
percent decrease = ($445.81 - $393.36) / $445.81 x 100%
percent decrease = $52.45 / $445.81 x 100%
percent decrease = 0.1175 x 100%
percent decrease = 11.75%
Therefore, the percent decrease in the price of the TV is 11.75%.
Which angle between -0° and -36° is coterminous with 887?
Answer:
Step-by-step explanation:
To find the coterminal angle with 887, we can add or subtract any multiple of 360°.
Adding a multiple of 360°:
887 + n(360)
where n is an integer.
Subtracting a multiple of 360°:
887 - n(360)
where n is an integer.
To find the angle between -0° and -36°, we need to subtract a multiple of 360° from 887 to get an angle between -0° and -36°.
887 - n(360) = -x
where x is the angle between -0° and -36°.
We can solve for x:
x = 887 - n(360)
We want x to be negative, so we need to choose a value of n such that 887 - n(360) is less than 0.
If we set n = 3, then:
x = 887 - 3(360) = 47
So, the angle between -0° and -36° that is coterminal with 887 is 47 degrees.
a distribution of values is normal with a mean of 128.3 and a standard deviation of 80.9.find p36, which is the score separating the bottom 36% from the top 64%. p36 = ___
The score separating the bottom 36% from the top 64%. p36 = 97.43
To find the score that separates the bottom 36% from the top 64%, we need to find the z-score corresponding to the 36th percentile and then use it to calculate the corresponding raw score.
First, we find the z-score using a standard normal table or calculator:
z = invNorm(0.36) = -0.379
Next, we use the formula:
z = (x - mu) / sigma
where x is the raw score, mu is the mean, and sigma is the standard deviation.
Plugging in the given values, we get:
-0.379 = (x - 128.3) / 80.9
Solving for x,
x = -0.379 * 80.9 + 128.3 = 97.43

In a circle with radius 7, an angle measuring π radians intercepts an arc. Find the length of the arc in simplest form.
Answer: the length of an arc intercepted by an angle in a circle is L = rθ, where L is the length of the arc, r is the radius of the circle, and θ is the central angle in radians.
Using this formula, we can find the length of the arc intercepted by an angle of π radians in a circle with radius 7:
L = rθ = 7π/1 = 7π
Therefore, the length of the arc is 7π units. This is already in its simplest form since π is a constant that cannot be simplified further.

How much pure alcohol must a pharmacist add to 10cm^(3) of a 8% alcohol solution to strengthen it to a 80% solution? cubic centimeters
36 cm³ of pure alcohol is added to 10 cm of an 8% alcohol solution to strengthen it to an 80% solution.
What is the solution?
A particular kind of homogenous mixture made up of two or more substances is known as a solution. A solute is a substance that has been dissolved in a solvent, which is the other substance in the mixture.
Here, we have
Given: a pharmacist adds 10cm^(3) of an 8% alcohol solution to strengthen it to an 80% solution.
Let x represent the volume of pure alcohol (100%) in cm³ needed to be added.
x × 100% + 10 cm³ × 8% = 80% × (x + 10 cm³)
x × 1 + 10 × 0.08 = 0.8 × (x + 10)
x + 0.8 = 0.8x + 8
0.2x = 7.2
x = 36 cm³
Hence, 36 cm³ of pure alcohol is added to 10 cm of an 8% alcohol solution to strengthen it to an 80% solution.

What is the employee's net pay after taxes if he works 52.5 hours in one week? Enter the answer in the box.
The employee's net pay after taxes if he works 52.5 hours in one week is $616.875.
What is the net pay?The net pay is the difference between the gross periodic pay or earnings less statutory deductions, including income taxes.
Normal hourly rate = $15
Normal weekly hours = 40 hours
Overtime rate = 1¹/₂ of $15 = $22.50
Income tax rate = 30%
Total hours worked in one week = 52.5 hours
Overtime hours = 12.5 (52.5 - 40)
Normal weekly gross pay = $600 ($15 x 40)
Overtime pay = $281.25 ($22.50 x 12.5)
Total pay for the week = $881.25
Income tax = $264.375 ($881.25 x 30%)

accomplish the task?
a) 15 minutes
b) 8 minutes
c) 10 minutes
d) 12 minutes
e) 13 minutes
The minimum time that Melissa will need to accomplish the task are 15 minutes.
How much time will Melissa require to complete this task?To start let's calculate the time she needs to count the sheets Melissa will transfer:
Sheets to be counted: 18 (Melissa can just count 18 sheets rather than 82 as there are 100 sheets in a pack) 100 - 82 = 18.
Time to count 3 sheets: 1 second
1 second = 3 sheets
x = 18 sheets
x = 18 x 1 / 3 = 6 seconds
6 seconds + 3 seconds to transfer the package = 9 seconds
Finally, let's calculate the total time by multiplying by the number of packs.
9 x 100 = 900 seconds / 60 = 15 minutes.

Here’s the question
The value of 2 miles = 3520 yards and 3 miles = 5280 yards. 2 yards = 6 feet and 3 yards = 9 feet. 2 feet = 2 x 12 inches = 24 inches and 3 feet = 36 inches.
What is SI unit conversion?The International System of Units (SI) units may be used in trade and commerce, grants and other business-related activities, educational information, and as guidelines in publications to improve understanding of the metric system. The SI units may be interpreted or modified for use in the United States by the Secretary of Commerce through the National Institute of Standards and Technology.
Multiply the number of miles by 1760:
1 mile = 1760 yards
2 miles = 2 x 1760 yards = 3520 yards
3 miles = 3 x 1760 yards = 5280 yards
Multiply the number of yards by 3, since there are 3 feet in a yard.
1 yard = 3 feet
2 yards = 2 x 3 feet = 6 feet
3 yards = 3 x 3 feet = 9 feet
Multiply the number of feet by 12, since there are 12 inches in a foot.
1 foot = 12 inches
2 feet = 2 x 12 inches = 24 inches
3 feet = 3 x 12 inches = 36 inches
Hence, the value of 2 miles = 3520 yards and 3 miles = 5280 yards. 2 yards = 6 feet and 3 yards = 9 feet. 2 feet = 2 x 12 inches = 24 inches and 3 feet = 36 inches.

the graph of y=f(x) is shown below find all values of x where f(x)=1
the values of x where f(x) = 1 for the function y = x^2 - 2x + 1 are x = 0 and x = 2.
general steps to find all values of x where f(x) = 1 for a given function y = f(x):
1. Set f(x) equal to 1: f(x) = 1.
2. Solve the equation for x. This may involve algebraic manipulation or using techniques such as factoring, completing the square, or using the quadratic formula, depending on the form of the equation.
3. If the equation has multiple solutions, list them all as the values of x where f(x) = 1. If the equation has no solutions, then there are no values of x for which f(x) = 1.
For example, if the function is y = x^2 - 2x + 1, then setting f(x) = 1 gives:
x^2 - 2x + 1 = 1
Simplifying this equation by subtracting 1 from both sides, we get:
x^2 - 2x = 0
Factoring out x, we get:
x(x - 2) = 0
This equation is satisfied when either x = 0 or x = 2. Therefore, the values of x where f(x) = 1 for the function y = x^2 - 2x + 1 are x = 0 and x = 2.

Luis plays basketball for WVC. For the free throws, he makes the
shot 75% of the time. He must now attempt two free throws. Probability that Luis makes the first
shot is 0.75. The probability Luis makes the second shot is 0.75. The probability Luis makes the
second free throw given that he made the first is 0.85. Calculate the probability that Luis makes
both free throws.
Please write your answer as a decimal. Round your answer to the third decimal place.
Let's use the conditional probability formula to calculate the probability that Luis makes both free throws:
P(both free throws) = P(makes first) * P(makes second | makes first)
We are given that:
P(makes first) = 0.75
P(makes second | makes first) = 0.85
So we can substitute these values in the formula:
P(both free throws) = 0.75 * 0.85
P(both free throws) = 0.6375
Therefore, the probability that Luis makes both free throws is 0.6375, or 0.638 rounded to the nearest thousandth.
