HELP Whatisthedifferencebetweenthe4.1%simpleinterestpaidon$2,750for4yearsandthe3.8% interest compounded annually on the same amount over the same period of time? Show your work.
Answers
Answer: Simple interest amount larger by $9.00
Step-by-step explanation:
Simple interest of 4.1% on $2,750 for 4 years:
Formula for simple interest is:
= Amount * (1 + rate * no. of periods)
= 2,750 * ( 1 + 4.1% * 4)
= 2,750 * 1.164
= $3,201
Compound interest of 3.8% on $2,750 for 4 years:
= Amount * (1 + rate) ^ no. of periods
= 2,750 * ( 1 + 3.8%)⁴
= $3,192
Difference:
= 3,201 - 3,192
= $9.00

How many different 3-letter codes can be formed from the word DUPLICATE? Without repeating the letters.
Answers
Answer:
There are 504 different codes.
Step-by-step explanation:
First some definitions:
If we have a set of N elements and we want to make combinations of K of these elements, the total number of different combinations is:
[tex]C(N, K) = \frac{N!}{(N - K)!*K!}[/tex]
And in the case of codes we need to also take in account the permutations of the elements (because is not the same DAC as CDA)
For a set of K different elements, the number of permutations is K!
We can not duplicate letters, then the first thing we need to do is to count the al the unique letters that appear in the word duplicate, these are:
{D, U, P, L, I, C, A, T, E}
We have a total of 9 letters, and the code must have 3, then:
N = 9
K = 3
The total number of different combinations is:
[tex]C(9, 3) = \frac{9!}{(9 - 3)!*3!}[/tex]
And each one of these combinations needs to be multiplied for the different permutations, then the total number of different codes is:
[tex]codes = \frac{9!}{(9 - 3)!*3!}*3! = \frac{9!}{(9 - 3)!} = \frac{9!}{6!} = 9*8*7 = 504[/tex]

Answers
Responder:
- 30 ° C
Explicação passo a passo:
Dado que :
A temperatura diminui 1 ° para cada 200 m afastados da superfície terrestre
Temperatura na superfície da terra = 20 ° C
Temperatura atmosférica a uma altura de 10 km de. Superfície Terrestre :
Queda de temperatura para uma altura de 10 km de distância;
10km = 10 * 1000 = 10.000 m
1 * (10000/200)
1 * 50
= 50 ° C
Portanto ;
Temperatura da superfície terrestre - 50 ° C

the perimeter of a rectangle is 24cm. If the length is 7cm, find the width.
Answers
Answer:
perimeter of rectangle=2(l+b)
24cm = 2(7cm+w)
24cm =14cm+2w
24cm - 14cm = 2w
10cm=2w
10cm/2=w
5cm=width.
Answer:
the perimeter of a rectangle = 2(l+b)
length = 7cm
2(7+b) = 24
7+b = 24/2 = 12
b=12-7 = 5
width = 5cm

The sum of three consecutive even numbers is 108. Write and evaluate an expression in terms of x to determine the smallest of the three numbers. Include parentheses in your expression.
Answers
Answer:
[tex]34[/tex]
Step-by-step explanation:
Let the first number be [tex]x[/tex]
The next number be [tex]2[/tex] more than the previous as it is an even number
The second number is [tex]x+2[/tex]
and the last number is [tex]x+4[/tex]
The sum of the numbers is [tex]108[/tex], so the expression will be
[tex]x+(x+2)+(x+4)=108[/tex]
[tex]\Rightarrow 3x+6=108[/tex]
[tex]\Rightarrow x=\dfrac{108-6}{3}[/tex]
[tex]\Rightarrow x=34[/tex]
The smallest of the three numbers is [tex]34[/tex].

Using that, you need to find the radius (which is one half of the diameter) 72/2=36
That is when you can plug the radius in: Circumference=2pi36
2*36=72. 72*pi is 72pi, or if you want to use 3.14, 72*3.14=226.08

Step-by-step explanation:
The median value of a distribution is obtained by :
FIRSTLY : Arranging the data in order usually ascending order.
Then the 50th percentile of the data is determined , the value which falls in the 50th percentile is the median of the distribution. The 50th percentile is the exact mid value of the distribution.
This describes the exact same way Tia was chosen in the scenario described above. Hence the measure of the center described is the Median.

The Cheer Squad is raising money to pay for their trip to the State Finals. They already have $1200 and they are selling really big candy bars for $10 each
If they need at least $3000, how many candy bars do they need to sell? Write an inequality and solve it
Answers
Answer:
10c + 1200 ≥ 3000, c≥ 180
Step-by-step explanation:
We know that they need at least $3000; meaning, it may be $3000 or more. This leaves us with eliminating the bottom two choices.
We then look at the first two choices. If we were to subtract from 1200, we would not know the total income amount that has been gained. It would also eventually give us negative numbers. We cannot have a negative amount earned. Instead, we would use the 10c+1200 because this would allow us to visualize that it needs to be greater than or equal to 3000
