need help with surface area of a cone

Answer:  A; The probability of landing on blue is greater than the probability of landing on purple.

Step-by-step explanation: This statement is true because you need to analyze the problem. Since there is a 3/6 or 1/2 chance of getting a blue, it is higher than getting a purple spot, which is 2/6 or 1/3. So, we can model our answer as:

3/6 > 2/6

or

1/2 > 1/3

Answer:

Step-by-step explanation:

please follow me

If you already chopped 4 walnuts and you have only gotten 1/4 cup of the chopped walnuts, it means that each walnut yields 1/4 cup / 4 walnuts = 1/16 cup of chopped walnuts.

To find out how much more chopped walnuts you need, we can subtract the amount you have from the total amount the recipe calls for:

1 cup - 1/4 cup = 3/4 cup

So you need 3/4 cup of chopped walnuts more.

To find out how many more walnuts you should chop, divide the amount you need by the amount each walnut yields:

3/4 cup / (1/16 cup/walnut) = 12 walnuts

So you should chop 12 more walnuts to get the desired amount.

Answer:

x = 28

Step-by-step explanation:

Consider the two triangles ΔAPR and ΔCDR

We see that AP ║ CD

Therefore m∠PAR = m∠CR, m∠APR= m∠CDR
Angle ∠R is common to both triangles

So the triangles are similar

Therefore the ratios of the sides must be the same ratio

[tex]\dfrac{AR}{CR} = \dfrac{PR}{DR}\\\\[/tex]

AR = x + 10

CR = x

PR = 42 + 15 = 57

DR = 42

PR = 42 + 15 = 57

Plugging in the values for these sides:

[tex]\dfrac{x + 10}{x} = \dfrac{57}{42}\\[/tex]

Cross-multiplying we get

[tex]42(x + 10) = 57x\\\\42x + 420 = 57x\\\\420 = 57x - 42x = 15x\\\\15x = 420\\\\x = 420/15\\\\= 28[/tex]

if you want to achieve your goal in 20 year, you would have to invest 1879.790424 at the end of each month for 240 months. you will have 800,000 after 20 years.

Step-by-step explanation:

rate of return is 5.3% compounded monthly.

number of years = 40.

future value = 800,000

interest rate per month is 5.3% / 12 = .4416666....%

number of time periods if 40 * 12 = 480

payment required at the end of each month is equal to 484.5267545

your total payments are 480 * 484.5267545 = 232,572.8422

total interest earned would be 800,000 minus 232,572.8422 = 567,427.1578

if you want to achieve your goal in 20 year, you would have to invest 1879.790424 at the end of each month for 240 months.

you will have 800,000 after 20 years.

The monthly mortgage payment for a $204,000 home with a 10% down payment and a 30 year loan at an interest rate of 3.5% would be approximately $808.44.

To calculate the monthly mortgage payment for a $204,000 home with a 10% down payment and a 30 year loan.

We'll need to first calculate the amount of the loan and then use the following formula to calculate the monthly payment:

M = P * r * (1 + r)^n / ((1 + r)^n - 1)

First, we'll calculate the down payment:

Down payment = 204,000 * 0.10 = $20,400

Next, we'll calculate the loan amount:

Loan amount = 204,000 - 20,400 = $183,600

Now, we'll need to convert the 30 year loan term into the number of payments (n) and the interest rate into the monthly interest rate (r):

n = 30 years * 12 months/year = 360 payments

r = (Annual interest rate) / 12 months/year

Assuming an annual interest rate of 3.5%, the monthly interest rate would be:

r = 0.035 / 12 = 0.002917

Finally, we can plug the values into the formula to calculate the monthly mortgage payment:

M = 183,600 * 0.002917 * (1 + 0.002917)^360 / ((1 + 0.002917)^360 - 1) = $808.44

Therefore, the monthly mortgage payment for a $204,000 home with a 10% down payment and a 30 year loan at an interest rate of 3.5% would be approximately $808.44.

If the economy is producing 12 units of guns and 4 units of butter, the opportunity cost of increasing the production of butter from 4 units to 11 units is 4 units of guns.

In Economics, an opportunity cost is sometimes referred to as alternative forgone and it can be defined as the value, profit or benefits that are given up and forfeited by an individual or business organization, in order to choose or acquire something that is deemed most significant at a particular point in time.

This ultimately implies that, the opportunity cost of owning or earning a thing is the alternative that is foregone in the attainment or earning of another value, profit or benefits.

Cost increase = 11 units - 4 units = 7 units of butter.

In this context, we can reasonably infer and logically deduce that the opportunity cost of 7 more units of butter would be 4 units of guns.

It will take Rachel 5 months to pay off her debt at her current monthly payment rate.

Interest rate is a percentage that represents the amount of interest charged by a lender to a borrower for the use of money. It is used to calculate the interest that will accrue on a loan or deposit over a specific period of time, and is usually expressed as an annual rate. It is a key component in determining the cost of borrowing money, and affects the amount that must be paid back to the lender, including the principal amount and any additional interest charges.

Rachel's monthly payment of $320 will only cover the interest on her debt and will not significantly reduce the outstanding balance. She would need to pay more each month or find a way to reduce the interest rate in order to pay off her debt in a reasonable amount of time.

To calculate the time it will take for Rachel to pay off her debt, we can use the following formula:

n = ceil(log(P/A) / log(1 + r))

where n is the number of payments, P is the initial balance, A is the monthly payment, and r is the monthly interest rate (expressed as a decimal).

In this case, P = $8,975, A = $320, and r = 17% / 12 = 0.17 / 12 = 0.01417.

So, n = ceil(log($8975 / $320) / log(1 + 0.01417)) = ceil(log(28.09375) / log(1.01417)) = ceil(4.3626) = 5.

It will take Rachel 5 months to pay off her debt at her current monthly payment rate. This means that it will take her just over 4 years to pay off the debt, assuming no additional purchases are made on the card and the interest rate does not change.

As for shopping for a new card, Rachel should consider a card with a lower interest rate. This will allow her to pay off her debt more quickly and save money in interest charges. She may also consider a balance transfer card with an introductory 0% interest rate, which would give her time to pay off the debt without accruing interest. However, she should be aware of any balance transfer fees that may apply. It is best for Rachel to compare options and read the fine print before making a decision.

To show that x-3 and x+5 are factors of x^4+2x^3-16x^2-2x+15, we can use polynomial division, synthetic division, and the Remainder theorem.

Using long division, we can divide x^4+2x^3-16x^2-2x+15 by x-3:

x^4 + 2x^3 - 16x^2 - 2x + 15

÷ x - 3

_________________________

  x^3 + 5x^2 - 14x - 12

   |__________

      -3x^3 + 17x^2 + 26x + 36

          |_________

                -14x^2 - 23x - 36

                     |_________

                          -15x + 72

                               |___

                                  57

So, the remainder is 57, which means x^4 + 2x^3 - 16x^2 - 2x + 15 = (x - 3)(x^3 + 5x^2 - 14x - 12) + 57.

Using synthetic division, we can divide x^4 + 2x^3 - 16x^2 - 2x + 15 by x+5:

1   2    -16   -2   15

   x + 5 |x^4 + 2x^3 - 16x^2 - 2x + 15|

____________________________

        x^3 - 3x^2 + 21x + 75

So, the remainder is 0, which means x^4 + 2x^3 - 16x^2 - 2x + 15 = (x + 5)(x^3 - 3x^2 + 21x + 75).

Using the Remainder theorem, we know that if a polynomial p(x) is divided by x-a, the remainder is p(a). So, when we plug in x=3, the remainder should be p(3) = 57. When we plug in x=-5, the remainder should be p(-5) = 0. This confirms that x-3 and x+5 are indeed factors of x^4 + 2x^3 - 16x^2 - 2x + 15.
