Suppose payments were made at the end of each month into an ordinary annuity earning interest at the rate of 2.5%/year compounded monthly. If the future value of the annuity after 10 years is $60,000, what was the size of each payment? (Round your answer to the nearest cent.) $

Answers

Answer:

Monthly payment= $440.71

Step-by-step explanation:

Giving the following information:

Mothly interest rate (i)= 0.025/12= 0.00208

Number of periods (n)= 12*10= 120 months

Future Value (FV)= $60,000

To calculate the monthly payment, we need to use the following formula:

Monthly payment= (FV*i) / [(1+i)^(n) - 1]

Monthly payment= (60,000*0.00208) / [(1.00208^120) - 1]

Monthly payment= $440.71

Sue has 4lbs 6oz of apples. Her younger brothers ate some and now she has 2lbs and 10oz how many lbs and oz of apples did they eat

Answers

Answer: 1 lbs 12 oz

Step-by-step explanation:

First and foremost, we should note that 16 ounces = 1 pound

Sue has 4lbs 6oz of apples. This in ounces will be:

= (4 × 16) + 6

= 64 + 6

= 70 ounces

Her younger brothers ate some and now she has 2lbs and 10oz. The ounces of apples left will be:

= (2 × 16) + 10

= 32 + 10

= 42 ounces

Therefore, the amount they ate will be:

= 70 ounces - 42 ounces

= 28 ounces

Since 16 ounces = 1 pounds

= 1 pounds 12 ounces

= 1 lbs 12 oz

To solve the equation below, you would?

Answers

So many confusing details. So, I rephrase the question as:

Four volunteers picked up litters from the park.

Dominic collect 15 pieces less than Sarah. Sarah collects 12 more pieces than Piper. Piper collected 1/4 as many pieces of letter as Vaughn. Vaughn has collected nine more pieces of letter than everyone else combined. Let x represent the number of pieces of litter in Vaughn's Collection. Find x

Answer:

[tex]x = 72[/tex]

Step-by-step explanation:

Let:

[tex]D = Dominic;\ \ S = Sarah;\ \ P = Piper;\ \ V = Vaughn[/tex]

From the [rephrased] question, we have:

[tex]D = S - 15[/tex]

[tex]S = 12 + P[/tex]

[tex]P = \frac{1}{4}V[/tex]

[tex]V = 9 + D + S + P[/tex]

Substitute [tex]S = 12 + P[/tex] in [tex]D = S - 15[/tex]

[tex]D = 12 + P - 15[/tex]

[tex]D = P+12 - 15[/tex]

[tex]D = P-3[/tex]

Make V the subject in [tex]P = \frac{1}{4}V[/tex]

[tex]V = 4P[/tex]

Substitute: [tex]V = 4P[/tex], [tex]D = P-3[/tex] and [tex]S = 12 + P[/tex] in [tex]V = 9 + D + S + P[/tex]

[tex]4P= 9 + P - 3 + 12 + P +P[/tex]

Collect like terms

[tex]4P - P -P-P= 9 - 3 + 12[/tex]

[tex]P= 18[/tex]

Substitute [tex]P= 18[/tex] in [tex]S = 12 + P[/tex]

[tex]S = 12 +18[/tex]

[tex]S = 30[/tex]

Substitute [tex]S = 30[/tex] in [tex]D = S - 15[/tex]

[tex]D = 30 - 15[/tex]

[tex]D =15[/tex]

Substitute [tex]D =15[/tex], [tex]S = 30[/tex] and [tex]P= 18[/tex] in [tex]V = 9 + D + S + P[/tex]

[tex]V = 9 + 15 + 30 + 18[/tex]

[tex]V = 72[/tex]

x represents the number collected by Vaughan.

So:

[tex]x = 72[/tex]

Step-by-step explanation:

I need the answers for these

Answers

Answer:

x = 2

Step-by-step explanation:

Let's solve your equation step-by-step.

4 ( x − 1 ) = 2 ( 6 − 2 x )

Step 1: Simplify both sides of the equation.

4 ( x − 1 ) = 2 ( 6 − 2 x )

( 4 ) ( x ) + ( 4 ) ( − 1 ) = ( 2 ) ( 6 ) + ( 2 ) ( − 2 x ) (Distribute)

4 x + − 4 = 1 2 + − 4 x

4 x − 4 = − 4 x + 12

Step 2: Add 4 x to both sides.

4 x − 4 + 4 x = − 4 x + 12 + 4 x

8 x − 4 = 12

Step 3: Add 4 to both sides.

8 x −  4 + 4 = 12 + 4

8 x = 16

Step 4: Divide both sides by 8.

8 x / 8 = 16 / 8

x = 2

The cost c in dollars of manufacturing x bicycles at a production plant is given by th function shown below C(x)=5x^2-1000x+63,500. How many bicycles must be manufactured to minimize the cost

Answers

Answer:

100 bicycle

Step-by-step explanation:

Given the cost c in dollars of manufacturing x bicycles at a production plant expressed as C(x)=5x^2-1000x+63,500.

x is the number of bikes

To minimize the cost, dC/dx = 0

dC/dx = 10x - 1000

Since dC/dx = 0

0 = 10x - 1000

-10x = -1000

x = 1000/10

x = 100

Hence the number of bicycles that must be manufactured to minimize the cost is 100 bicycle

Which account has the greater​ principal? Select the correct answer below and fill in the answer boxes to complete your choice.

Answers

Answer:

Step-by-step explanation:

I=Prt

11.25=A(0.03)(15/12)

11.25=A(0.0375)

A=11.25/(0.0375)

A=$300

25=B(0.05)(15/12)

25=B(0.0625)

B=25/(0.0625)

B=$400

So account B has the greater principal.

Step-by-step explanation:

__________________________________________________________

FACTS TO KNOW BEFORE SOLVING :-

Let x be a number. ⇒ [tex]x^{\frac{1}{2}}[/tex] can also be written as [tex]\sqrt{x}[/tex].To make any variable the subject of any formula , we need to isolate it.

__________________________________________________________

According to the question ,

[tex]3m = \frac{(n + 1)^{\frac{1}{2} }}{4}[/tex]

Lets multiply both the sides by 4.

[tex]=> \frac{(n + 1)^{\frac{1}{2} }}{4} \times 4 = 3m \times 4[/tex]

[tex]=> (n + 1)^{\frac{1}{2} } = 12m[/tex]

It can be also written as :-

[tex]=> \sqrt{(n + 1)} = 12m[/tex]

Lets square both the sides.

[tex]=> [\sqrt{(n + 1)} ]^{2} = (12m)^{2}[/tex]

[tex]=> n + 1 =144m^2[/tex]

[tex]=> n = 144m^2 - 1[/tex]

Delaney is saving money in an account that offers 9% simple interest. She deposits 2000 from her grandmother into the account and makes no additional deposits or withdraws. How many years will it take to grow to 4,700

Answers

Answer:

15years

Step-by-step explanation:

Given data

Rate= 9%

Principal= $2000

Final amount= $4700

The simple interest formula is given as

A= P(1+rt)

Substitute

4700=2000(1+0.09*t)

4700= 2000+ 180t

4700-2000= 180t

2700=180t

t= 2700/180

t= 15 years

Hence the time is 15years

The rate of change when x increases and the first difference equal to 45.5 is 6.5. Then the correct option is A.

What is the slope?

The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.

The slope is given as

[tex]\rm Slope = \dfrac{Rise \ or \ fall}{Run}[/tex]

If x increases by 7 in each row of a table of values and the first differences are all equal to 45.5. Then the rate of change will be given by the slope.

[tex]\rm \\Slope = \dfrac{45.5}{7} = 6.5[/tex]

The rate of change is 6.5.
