Ms. Anderson deposits $7,000 into a savings account that pays a simple interest of 2% per year. What is the total amount of money that will be in her account at the end of 3 years?

Answers

Answer:

$7420

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 2%/100 = 0.02 per year,

then, solving our equation

I = 7000 × 0.02 × 3 = 420

I = $ 420.00

The simple interest accumulated

on a principal of $ 7,000.00

at a rate of 2% per year

for 3 years is $ 420.00.

Work out the size of an exterior and an interior angle of a regular 25-sided polygon.​

Answers

Answer:

14.4 degrees, 165.6 degrees

Step-by-step explanation:

Exterior angle of a regular polygon = 360 / number of faces, 360/25=14.4 degrees

Interior angle = 180 - exterior = 180 - 14.4 = 165.6 degrees

If someone does a non-mathematical answer just for the points, I will report them. Thank you.

Answers

Answer:

$1440.23

Step-by-step explanation:

The formula for calculating future value of a sum compounded at specified times =

FV = PV x (1 + r/m)^nm

FV = Future value  

P = Present value  

R = interest rate  

N = number of years

m = number of compounding

$1100 x ( 1 + 0.045 /12) ^12x6 = $1440.23

In a sample of 500 respondents, men account for 20% of all observations in the sample. What is the total number of females in the sample ?

Answers

The total number of women is 400.


Explanation: 20% of 500 is 100

A percentage is a way to describe a part of a whole. The total number of females in the sample are 400.

What are Percentages?

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Given that In a sample of 500 respondents, men account for 20% of all observations in the sample. Therefore, if we deduct the number of male from the total number of respondents, then we can get the total number of women.

Now, the total number of females in the sample are:

Total number of females in the sample

= Total number of respondents - Total number of males in the sample

= 500 - 20% of total respondents

= 500 - 20% of 500

= 500 - 0.20(500)

= 500 - 100

= 400

Hence, the total number of females in the sample are 400.

1*1/32=1/32

When x = 2, the value of 4⁰ × x⁻⁵ is 0.03125.

To evaluate the expression 4⁰ × x⁻⁵ when x = 2, we'll substitute the value of x into the expression and perform the necessary calculations.

First, let's evaluate 4⁰. Any number raised to the power of 0 is equal to 1. Therefore, 4⁰ = 1.

Next, let's evaluate x⁻⁵ when x = 2. A negative exponent indicates the reciprocal of the base raised to the positive exponent. So, x⁻⁵ = 1 / x⁵.

Substituting x = 2, we have 1 / 2⁵.

Now, we can simplify the expression:

1 / 2⁵ = 1 / 32 = 0.03125

Therefore, when x = 2, the value of 4⁰ × x⁻⁵ is 0.03125.

An architect is designing a house for the Frazier family. The Fraziers have asked that the cost of

the house be about $175,000 and are willing to deviate from this price no more than $20,000.

19 A) Write an open sentence involving an absolute value.

Answers

Answer:

║x - 175,000║≤ 20,000

Step-by-step explanation:

Let x be the amount the Fraziers are willing to pay. Since the house costs $175,000 and they are willing to deviate from this price no more than $20,000, so x =  $175,000 ± $20,000.

So, x - 175,000 = ± 20000

║x - 175,000║= 20,000

But we require  

║x - 175,000║≤ 20,000

which is our required open sentence.
