Stephanie
invests $6,688 in a savings
account with a fixed annual interest rate of
2% compounded 6 times per year. What
will the account balance be after 5 years?
Answer:
$7,390.15
Step-by-step explanation:
A = $7,390.15
A = P + I where
P (principal) = $6,688.00
I (interest) = $702.15
First, convert R as a percent to r as a decimal
r = R/100
r = 2/100
r = 0.02 rate per year,
Then solve the equation for A
A = P(1 + r/n)^nt
A = 6,688.00(1 + 0.02/6)^(6)(5)
A = 6,688.00(1 + 0.0033333333333333)^(30)
A = $7,390.15
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $6,688.00 at a rate of 2% per year compounded 6 times per year over 5 years is $7,390.15.
Mira buys a telescope that costs $180. She has to pay 4% sales tax. how much will she pay in all
Mira would pay $187.2
What is the formula for tax rate?"Tax rate = (Tax amount / Price before tax) × 100% "
What is the formula for tax amount?"Tax amount = Final price - Price before tax"
For given question,
Mira buys a telescope that costs $180.
⇒ Price before tax = $180
sales tax = 4%
Let 'm' be the tax amount.
Using the formula of tax rate,
⇒ Tax rate = (Tax amount ÷ Price before tax) × 100%
⇒ 4% = ([tex]\frac{m}{180}[/tex]) × 100%
⇒ 0.04 × 180 = m
⇒ m = 7.2
Using the formula for the tax amount,
⇒ Tax amount = Final price - Price before tax
⇒ Final price = Tax amount + Price before tax
⇒ Final price = 7.2 + 180
⇒ Final price = $187.2
Therefore, Mira would pay $187.2

Combine 4x and 3x = 7x:-
[tex]\tt 7x-3=67[/tex]

Loojk ate the rectangle a) A square has the same area as the rectangle above what is the side length of this square
Answer: The length of one side of the square is 10 sq cm.
Step-by-step explanation: Area of the rectangle = 4 x 25 = 100 sq cm.
Area of a square = s x s, where s is the length of the side of the square.
So, s x s = 100
Or, s^2 = 100
And, s = sqrt(100) = 10

Answer:
sine=opposite/hypotenuse
cosine=adjacent/hypotenuse
tangent=opposite/adjacent
a: 42
b: 135 km/h
Step-by-step explanation:
For part A, you are given the adjacent and opposite side lengths so you need to use the tangent formula. On the calculator, it is tan^-1 (90/100)
For part B, I used the pythagorean theorem and did 100^2+90^2= 18100 and then took the square root of that to get 135.

According to these three facts, which statements are true?
Circle W has center (−3, 0) and radius 8.
Circle V is a translation of circle W, 2 units down.
Circle V is a dilation of circle W with a scale factor of 2.
Select each correct answer.
The radius of circle V is 16.
The center of circle V is (−5, 0).
Circle V and circle W have the same center.
Circle V and circle W are similar.
a.
Circle W centre is (-3,0) - (0,-2)* = (-3,-2)
*note that the centre of the circle W is going down by 2 units this only affects the y axis hence the substraction
A dilation of a factor of 2 does not change the centre of the circle rather the radius ( the size of the circle decreases and hence the radius)
So now the radius becomes 8 UNITS/2 = 4UNITS
From the statements given,neither is correct
The population of a village has increased this year by 8 percent.This year it's population is 10,800.How much was it's population last year?
Answer:
SOLUTION:-
Let,last year population be x.We have last year population+Increased population=10,800[tex]x + 8\% \: of \: x = 10800[/tex]
[tex]\displaystyle{x + \frac{8x}{100} = 10800 }[/tex]
[tex]\displaystyle{ \frac{100x + 8x}{100} = 10800}[/tex]
[tex]\displaystyle{ \frac{108x}{100} = 10800}[/tex]
[tex]108x = 10800 \times 100[/tex]
[tex]108x = 1080000[/tex]
[tex]x = \displaystyle{ \frac{1080000}{108} }[/tex]
[tex]x = 10000[/tex]
Therefore,required last year population=10000
Answer:
The Correct Answer is 10,000.
Step-by-step explanation:
Becuase The Question itself is providing us that this year it increased by 8%. Then the said that the total population for this year is 10,800. So, that tells us that the 8% equal 800. 10,000+800=10,800.
10,800-800=10,000
The correct answer is 10,000.

Helium is a gas lighter than air that is used in balloons. The density of
helium is approximately 0.14 kilograms per cubic meter. You get 5 helium balloons for your 5th birthday, each with a volume of 14 cubic meters. How many kilograms of helium do the balloons contain, to the nearest hundredth?
Using proportions, given the density value, it is found that the ballons contain 9.8 kilograms of helium.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, we have that each ballon contain 0.14 kilograms per cubic meter.
You get 5 ballons, each with 14 cubic meters, hence the total volume is given by:
V = 5 x 14 = 70 m³.
Applying the density, we have that the total mass is given by:
M = 0.14 x 70 = 9.8 kilograms.

If the measure of angle 1 is (3 x minus 4) degrees and the measure of angle 2 is (4 x + 10) degrees, what is the measure of angle 2 in degrees?
Answer:
its 58
Step-by-step explanation:
The measure of angle 2 is 58 degrees
How to determine the measure of angle 2?The figure that completes the question is added as an attachment
The given parameters are:
Angle 1 = 3x - 4Angle 2 = 4x + 10Both angles add up to 90 degrees.
So, we have:
3x - 4 + 4x + 10 = 90
Evaluate the like terms
7x = 84
Divide both sides by 7
x =12
Substitute x =12 in Angle 2 = 4x + 10
Angle 2 = 4 * 12 + 10
Evaluate the expression
Angle 2 = 58
Hence, the measure of angle 2 is 58 degrees
