Answer:
$139
Step-by-step explanation:
The formula for compound interest =
A = P(1 + r/n)^nt
Where
P = Principal
r = Interest rate
n = Compounding frequency
t = time in years
A = Amount after t years
For Melanie
Melanie invested $8,600 in an account paying an interest rate of 2 7/8% compounded monthly.
Rate = 2 7/8% = 23/8% = 2.875%
Time = 10 years
n = monthly = 12
First, convert R percent to r a decimal
r = R/100
r = 2.875%/100
r = 0.02875 per year,
Then, solve our equation for A
A = P(1 + r/n)^nt
A = 8,600.00(1 + 0.02875/12)^(12)(10
A = 8,600.00(1 + 0.002395833)^(120)
A = $11,460.64
For Oliver
Oliver invested $8,600 in an account paying an interest rate of 2 3/4 % compounded daily.
Rate = 2 3/4% = 11/4% = 2.75%
Time = 10 years
n = daily = 360 days
First, convert R percent to r a decimal
r = R/100
r = 1.375%/100
r = 0.01375 per year,
Then, solve our equation for A
First, convert R percent to r a decimal
r = R/100
r = 2.75%/100
r = 0.0275 per year,
Then, solve our equation for A
A = P(1 + r/n)^nt
A = 8,600.00(1 + 0.0275/360)^(360)(10)
A = 8,600.00(1 + 7.6389E-5)^(3600)
A = $11,322.05
After 10 years, how much more money would Melanie have in her account than Oliver, to the nearest dollar?
This is calculated as
$11,460.64 - $11,322.05
=$ 138.59
Approximately to the nearest dollar = $139

What is the value of n that makes 10n = 50 true?
Answer:
n=5
Step-by-step explanation:
50 divided by 10 = 5
Answer:
n=5
Step-by-step explanation:
To figure out n we must divide 50 and 10.
50 ÷ 10 = 5
So n=5
Evaluate ba+cd if a=7/8 , b=−7/16 , c=0.8 , and d=1/4 . Write your answer as a mixed number in simplest form.
Answer:
-117/640
Step-by-step explanation:
ba + cd
b= -7/16
a= 7/8
c= 08.(4/5)
d= 1/4
Hence it can be calculated as follows
-7/16×7/8 + 4/5×1/4
-49/128 + 1/5
-246+128/640
= -117/640
Answer: -2 11/20

Step-by-step explanation:
A cube has a volume of 2197 m. Its surface is to be painted. Each can of paint covers about 40 m2
How many cans of paint are needed?
Answer:
25 cans
Step-by-step explanation:
Let the side length of the cube be s m
Therefore,
[tex] {s}^{3} = 2197 \\ \\ {s}^{3} = {13}^{3} \\ \\ \implies \: s = 13 \: m \\ \\ total \: surface \: area \: of \: cube \\ = 6 {s}^{2} \\ = 6( {13})^{2} \\ = 6 \times 169 \\ = 1,014 \: {m}^{2} \\ \\ no \: of \: cans \: of \: paint \: needed \\ = \frac{1014}{40} \\ = 25.35 \: \\ \approx \: 25[/tex]
what is the m<2 = ?
Answer:
The area equal to a square that is 1 meter on each side. Used for measuring areas of rooms, houses, blocks of land, etc
Step-by-step explanation:
does 20, 40, 30 form a pythagorean triple
Answer:
Step-by-step explanation:
If it is a Pythagorean Triple the hypotenuse and the legs of a right triangle will all be integer values where
c^2=a^2+b^2
In this case, this isn’t even a right triangle as
20^2+30^2=40^2
400+900=1600
1300!=1600
because 1300 does not equal 1600 this is not a Pythagorean Triple.

1. The function f(x) = -0.05(x2 - 26x - 120) represents the path coming out of the cannon. If x is the horizontal distance from the cannon, what does f(x) represent? (1 point)
Answer:
f(x) represents the vertical height of the cannon
Step-by-step explanation:
The given function is presented as follows;
f(x) = -0.05·(x² - 26·x - 120)
Given that 'x' represent the horizontal path of the cannon and the function describes the path of the cannon, we have that the vertical height reached by the cannon as it moves along the horizontal path is given as the function f(x)
Therefore, we have;
f(0) = -0.05·(0² - 26×0 - 120) = -0.05 × -120 = 6
f(0) = 6
The starting height of the cannon = 6
The maximum height reached by the cannon is given as follows;
f'(x) = d(-0.05·(x² - 26·x - 120))/dx = -0.05·d(x² - 26·x - 120)/dx = -0.05×(2·x - 26)
f'(x) = -0.05×(2·x - 26)
f'(x) = 0 At maximum height, therefore, we have;
-0.05×(2·x - 26) = 0
(2·x - 26) = 0
2·x = 26
x = 26/2 = 13
x = 13
f(13) = -0.05·(13² - 26×13 - 120) = 14.45
The maximum height = 14.45
Therefore;
f(x) = The vertical height of the cannon
Kimberly wants to get a backpack that cost $35 it is now on sale for 15% off she has to pay 7.5% sales tax what is the sales price of the backpack
Answer:
$44.26
Step-by-step explanation:
The computation of the sales price is shown below:
Its cost is $35
There is a sale off i.e. 15% off
And, the sales tax rate is 7.5%
SO, the sale price is
= $35 × 100 ÷ 85 + ($35 × 100 ÷ 85) × 7.5%
= $41.17 + $41.17 × 7.5%
= $41.17 + $3.09
= $44.26
Hence, the sales price is $44.26

x⁰ = 360 degree- ( 246⁰ + 66⁰)
= 360 degree- 312⁰
= 48 ⁰
Answer:
x = 114
Step-by-step explanation:
Remark
You are trying to figure out what the arc is in degrees. The arc formula is
Intersect angle = 1/2( the furthest arc - the smaller closer arc).
Givens
Intersect angle = 66 degrees
Closer arc = x
Further or largest Arc = 246
Solution
66 = 1/2 (246 - x) Multiply both sides by 2 and remove the brackets.
132 = 246 - x Subtract 246 from both sides.
132 - 246 = - x
- 114 = - x Multiply both sides by -1
-1 (-114) = -1 * (-x)
x = 114
