Joshua invested $750 in an account paying an interest rate of 3\tfrac{1}{4}3 4 1 ​ % compounded quarterly. Josiah invested $750 in an account paying an interest rate of 2\tfrac{5}{8}2 8 5 ​ % compounded annually. After 18 years, how much more money would Joshua have in his account than Josiah, to the nearest dollar?

Answers

Answer:

Due to the difference in the interest rate and the quarterly compounding, Joshua will have $212.24 more than Josiah.

Step-by-step explanation:

Giving the following information:

Joshua:

Initial investment (PV)= $750

Interest rate (i)= 0.0341/4= 0.008525

Number of periods (n)= 18*4= 72 quarters

Josiah:

Initial investment (PV)= $750

Interest rate (i)= 0.0285

Number of periods (n)= 18 years

To calculate the future value of each one, we need to use the following formula:

FV= PV*(1 + i)^n

Joshua:

FV= 750*(1.008525^72)

FV= $1,381.98

Josiah:

FV= 750*(1.0285^18)

FV= $1,169.74

Due to the difference in the interest rate and the quarterly compounding, Joshua will have $212.24 more than Josiah.

Castel and Chelsea are selling pies for a school fundraiser. Customers can buy cherry pies and lemon meringue pies. Castel sold 1 cherry pie and 5 lemon meringue pies for a total of $69. Chelsea sold 5 cherry pies and 7 lemon meringue pies for a total of $129. Find the cost each of one cherry pie and one lemon meringue pie.

Answers

Answer:

the cost each of one cherry pie and one lemon meringue pie is 9 and $12 respectively

Step-by-step explanation:

The computation of the cost of one cherry pie and the lemon meringue pie is shown below:

Let us assume the cherry pie be x

And, the lemon meringue pie be y

So according to the question

x + 5y = $69

5x + 7y = $129

Now multiply by 5 in the equation 1

5x + 25y = $345

5x + 7y = $129

18y = $216

y = $12

And, x would be

x + 5($12) = $69

x = $9

Hence, the cost each of one cherry pie and one lemon meringue pie is 9 and $12 respectively

Answers

Answer:

∠A = 70°

Step-by-step explanation:

I'm... guessing this is what you mean? It would've been helpful if you'd provided pictures.

Since all parallelograms consist of two pairs of vertically opposite angles, ∠A and ∠C are equivalent.

Which means that 2x + 50 = 3x + 40.

In which you solve the equation.

2x + 50 = 3x + 40

-2x           -2x

50 = x + 40

-40  -40

x = 10

Now, to find ∠A, substitute x into the equation:

∠A = 2x + 50

x = 10

∠A = 20 + 50

∠A = 70

Hence, ∠A = 70°

Sally's cell phone bill os expected to increase by 7.5% next year . If b represnts the current bill, which expression represent the expected cost of the cell phone bill next year?

Answers

Answer:

The expression represent the expected cost of the cell phone bill next year is: c=1.075b.

Step-by-step explanation:

With the information provided, you can say that the expected cost of the cellphone bill next year would be equal to the current bill multiplied for 1 plus the increase in decimal numbers, so the increased amount is added to the current cost. The equation would be:

c=b*(1+0.075)

c=b*1.075

c=1.075b

According to this, the answer is that the expression represent the expected cost of the cell phone bill next year is: c=1.075b.

C)
91°F to 98°F average July high temperature
D)
94°F to 95°F average July high temperature

Answers

Answer:

D

Step-by-step explanation:

Since it's talking abtou clusters, the only "cluster" like part there is there is where 94 and 95 are, so it has to be D.

Using the scatter plot and the range concept, it is found that the correct option is:

C)  91°F to 98°F average July high temperature

The range of a data-set is the set that contains all possible output values.

In this problem, the average July temperature is the output, plotted as function of the average January temperature, which is the input.

It varies from 91ºF to 98ºF, hence, the correct option is:

C)  91°F to 98°F average July high temperature
