Lillian is going to invest in an account paying an interest rate of 5.7% compounded continuously. How much would Lillian need to invest, to the nearest ten dollars, for the value of the account to reach $7,600 in 7 years?
Answer:
The amount Lilian needs to invest is $5,160
Step-by-step explanation:
The parameters of the amount Lilian is going to invest in an account are;
The interest rate the account pays = 5.7%
The final amount the investment is expected to reach after the given time period = $7,600
The number of years of the investment = 7 years
The formula for compound interest is presented as follows;
[tex]A = P \cdot \left(1 + \dfrac{r}{n} \right)^{n\cdot t}[/tex]
Where;
A = The final amount = $7,600
P = The amount Lilian is to invest
r = The interest rate = 5.7% = 0.057
n = The number of times the interest is applied per time period = 1
t = The number of period that passes = 7 (years)
Therefore, we get;
[tex]7,600 = P \cdot \left(1 + 0.057 \right)^{7}[/tex]
∴ P = 7,600/(1 + 0.057)⁷ = 5,155.7123754
The amount Lilian needs to invest (rounded to the nearest ten dollars) for the value of the account to reach $7,600 in 7 years, P = $5,160

Answer:
x = 5 or x = -5
Step-by-step explanation:
| a b |
| c d |
det = ad - bc
| x 4 |
| 3 x |
det = x * x - 4 * 3 = x^2 - 12
x^2 - 12 = 13
x^2 = 25
x^2 - 25 = 0
(x + 5)(x - 5) = 0
x = 5 or x = -5
The perimeter of a square patio is (8x - 28). What is the length of one side?
Answer:
Length is 7, Permimeter is 28
Step-by-step explanation:
Perimeter=4×side
(8x-28)=4×x [let length be x]
8x-28=4x
8x-4x=28
4x=28
x=28÷4
x=7
Length = x = 7
Perimeter=(8x-28)
=(7×8)-28
=56-28
=28

Answer:
x = 9
Step-by-step explanation:
Opposite sides of a parallelogram are equal.
16x - 15 = 11x + 30 Subtract 11x from both sides
16x - 11x - 15 = 30 Combine the left
5x - 15 = 30 Add 15 to both sides
5x = 30 + 15 Combine the right
5x = 45 Divide by 5
5x/5 = 45/5
x = 9
What is the value of x? *
3x + 10=3x - 28
Answer:
x = 27
Step-by-step explanation:
First of all the equation written on the question is incorrect, like not the image, this is because the angle of 3x + 10 and 3x - 28 is not the same, The equation will be 3x + 10 + 3x - 28 = 180
=> 6x - 18 = 180
=> 6x = 180 - 18
=> 6x = 162
=> x = 162 / 6
=> x = 27

Cindy throws one red and one blue regular (six-sided) fair dice. Find the probability that the sum of the two dice is greater than 2.
a 1/36
b 35/36
c 33/36
d 1
Answer:
5/36 is your answer.
Step-by-step explanation:
If the red die shows a "2", then the blue die must take on the values from the set {2,3, 4, 5, 6} in order for the sum of both dice to be larger than 4.
1+2=3
2+3 = 5
2+4 = 6
2+5 = 7
2+6 = 8
There are 6*6 = 36 total ways to roll two dice and exactly 5 ways to get the conditions stated above. The probability of getting a sum greater than 2 is 5/36
The probability that the sum of the two dice is greater than 2 will be 35/36. Then the correct option is B.
What is probability?Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences. Then the probability is given as,
P = (Favorable event) / (Total event)
Cindy throws one red and one blue regular (six-sided) fair dice. The total number of events will be
Total events = 6 x 6 = 36
The probability that the sum of the two dice is greater than 2 will be given as
P = 1 - 1 / 36
P = 35 / 36
The probability that the sum of the two dice is greater than 2 will be 35/36. Then the correct option is B.

Find the area of the figure.
Answer and Step-by-step explanation:
For this shape, we have to draw a line that goes through the point that is inside of the shape from top to bottom.
This creates a square and two triangles.
The area formula for a triangle is A = [tex]\frac{bh}{2}[/tex]
The area of a square is A = b*b
Half of 3 is 1.5.
Triangles (Area combined):
Since there are two triangles that are the same, we only need to find the area of of 1 triangle, and not divide by 2.
A = 3 × 1.5 = 4.5
Square:
A = 3 × 3 = 9
Now, we add them together to get the total area of the figure.
9 + 4.5 = 13.5
The area of the figure is 13.5 [tex]in^{2}[/tex].

Answer:

Step-by-step explanation:
−5x−5y= −30 10x+3y= −3
Answer:
x = -3, y = 9
Step-by-step explanation:
-5x - 5y = -30
x - y = 6
x = -y + 6
10x + 3y = -3
10(-y + 6) + 3y = -3 (plug in x from the previous equation)
60 - 10y + 3y = -3
60 - 7y = -3
-7y = -63
y = 9
x = -y + 6
x = -(9) + 6
x = -3

Did you mean: The manager of a youth soccer team bought 50 packages of socks for $10. Each. He estimated the total cost to be $5000. Create an equation that shows how many times more the manager's estimate, e, was than the actual cost, a.
Answer:
Estimated cost is 10 times more than the actual cost
Step-by-step explanation:
Packages of socks purchased = 50
Price per package = $10
Actual cost = total package purchased * price per package
Actual cost , a = 50 * $10 = $500
Estimated cost, e = $5000
Estimated costs / actual cost
$5000 / $500
= 10
Estimated cost is 10 times the actual cost

The Weston family spends a maximum of
$50.00 per month on entertainment. Write and
graph an inequality to represent this.
Answer:
y < 50x
Step-by-step explanation:
In order to graph this inequality, you first need to identify the important word(s) here to find the inequality sign; in this case, it would be "maximum of $50" a month. Since it's a maximum of $50 a month (or less than $50 a month), you can write it as:
Where m is months and c is total cost, c < 50m
If you need to graph this, you can write it as y < 50x. The cost is y since it's the output, and months is x since that's the input.
