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?
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.
Thomas puts $1100 into a savings account that earns 4.5% interest compounded monthly. How much money will he have in savings in 6 years?
If someone does a non-mathematical answer just for the points, I will report them. Thank you.
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

Evaluate 4^0×x^-5 when x=2 .
Answer:
1/32
Step-by-step explanation:
Anything to the power of 0 is 1.
1*x^-5 (negative power means the reciprocal)
1/2^5 = 1/32
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.

What is the value of p so that the expression 4(5 + n) is equivalent to 4(n + p) ?
Answer:
5
Step-by-step explanation:
4(5+n)=4(n+p)
20+4n=4n+4p
4p=20
p=20/4
p=5
Answer:
the value of p is 5
Step-by-step explanation:
the expression 4(5 + n) is equivalent to 4(n + p)
4(5+n)=4(n+p)
5+n=n+p
n+5=n+p
comparing each other
we get p=5

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

zahid is paid 774.72 for 36 hrs so,
he worked 43 hrs,
so no. of hours ot: 43-36
7 hrs
now we will find the half of 774.72
387.36
now add 774.72+387.36

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.
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.
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 ?
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.

A convex polygon has 13 sides when the interior angle sum is [tex]1980^{0}[/tex].
What is convex polygon?A polygon is called a convex polygon when no line segments between the points, goes inside. The boundaries of the convex polygon do not go inside and all the vertices are pointed outside away from the center. The interior angles of a convex polygon are less than 180°.
Given a convex polygon
For a convex polygon with n sides, the interior angle sum is [tex]180^{0}[/tex] × [tex](n-2)[/tex]
Let [tex]180^{0}[/tex] × [tex](n-2)[/tex] = [tex]1980^{0}[/tex]
⇒ n - 2 = 11
⇒ n = 11 + 2
⇒ n = 13
Thus, a convex polygon has 13 sides when the interior angle sum is [tex]1980^{0}[/tex].

Answer:
30
Step-by-step explanation:
In this picture, the angle, 30 degrees, is a part of the whole. we are looking for the value of X.
First we can take off 45 degrees, since the angle is lower than 30 degrees
Now we can take off 15 degrees, since the angle is too small.
And we can also take off 10 degrees since its way too small.
2x mean 2 times X.
The overall measurement is a 90 degree angle, indicated by the box.
90-30= 60
30 * 2 = 60.
The correct answer is 30.
