Step-by-step explanation:
Lucy have $6400 if she invests
$1200 at 15% interest
compounded quarterly?
Answer:
11.4 years
Step-by-step explanation:
We assume you want to know the time it takes for Lucy's investment of $1200 to have a value of $6400. The compound interest formula is good for finding that.
FV = P(1 +r/n)^(nt)
for principal P invested at rate r per year for t years, compounded n times per year. We want to find t such that ...
6400 = 1200(1 +0.15/4)^(4t)
16/3 = 1.0375^(4t) . . . . divide by 1200
log(16/3) = 4t·log(1.0375) . . . . take logarithms
t = log(16/3)/(4·log(1.0375)) ≈ 11.4
It will take about 11.4 years for Lucy's investment value to be $6400.

Answer:
I think they are both wrong
The correct way to solve it is this.
Step-by-step explanation:
Step 1: Subtract 4 from both sides.
[tex]-6x+4-4=-20-4[/tex]
[tex]-6x=-24[/tex]
Step 2: Divide both sides by -6.
[tex]\frac{-6x}{-6} =\frac{-24}{-6}[/tex][tex]x=4[/tex]
Answer:

This is a problem of equation part of Algebra.
Some important Algebra formulas.
(a + b)² = a² + 2ab + b²
(a − b)² = a² − 2ab − b²
(a + b)³ = a³ + 3a²b + 3ab² + b³
(a - b)³ = a³ - 3a²b + 3ab² - b³
a³ + b³ = (a + b)³ − 3ab(a + b)
a³ - b³ = (a -b)³ + 3ab(a - b)
a² − b² = (a + b)(a − b)
a² + b² = (a + b)² − 2ab
a² + b² = (a − b)² + 2ab
a³ − b³ = (a − b)(a² + ab + b²)
a³ + b³ = (a + b)(a² − ab + b²)
Here given, equation is [tex] - 6x + 4 = - 20[/tex]
Now,
-6x + 4 = -20
First we are separating variable and constant part.
So first we subtracting 4 from (-20) and get
[tex] - 6x = - 20 - 4[/tex]
or,[tex] - 6x = - 24[/tex]
Now (-24) is dividing by (-6) and get,
[tex]x = \frac{ - 24}{ - 6} \\ x = 4[/tex]
So, value of x is 4.

Step-by-step explanation:

[tex]\frac{3}{4} ^{6} -\frac{3}{4} ^{3}[/tex] = [tex]\frac{3}{4}^{6-3}[/tex] = [tex]\frac{3}{4}^{3}[/tex] = [tex]\frac{3 * 3 * 3}{4 * 4 * 4}[/tex] = [tex]\frac{27}{64}[/tex]

The sum of 9 consecutive numbers is 279. What is the sum of the first and the last number?
Let the first number = x
The second number would be x +1
3rd number = x +2
4th number = x +3
5th number = x+4
6th number = x+5
7th number = x +6
8th number = x +7
9th number = x+8
The sum is 279
Combine like terms in the 9 numbers to get: 9x + 36 = 279
Solve for x:
9x + 36 = 279
Subtract 36 from both sides:
9x = 243
Divide both sides by 9:
x =27
The first number is 27
The last number would be 27 + 8 = 35
The sum of the first and last would be 27 + 35 = 63

Answer: 102.9m
Step-by-step explanation: From A to C you can go from the diagonal path and then go around the circular path and then continue the diagonal path. In order to work out the length of the diagonal, you can simply use pythagoras as the triangle is right angled. So to find the length of the whole diameter, you should do 50 squared plus 80 squared and then square root the answer to get 94.34. But then you have to subtract the part of the diagonal line which the circle takes up, so we already know that the diameter of the circle is 15m so we simply do 94.34-15 to get 79.34. This means that we have found the length of the two diagonals, but now we need to find the length of half the circumference of the circle so that the path is complete and to find half the circumference, we'd do Pi multiplied by the diameter (15) and then divide the answer by 2 (because we are only finding the circumference for half of the circle as we have you go around the circle), leaving us with the answer of 23.56. We then add this to the 79.34 to get the answer of 102.9m. We know this is the shortest route as going along the edges of the rectangle would be 130m which is longer than 102.9m.

State if the three sides lengths form a right triangle.
13) 10cm, 49.5cm, 50.5cm
(I NEED HELP PLZ SHOW WORK)
I WILL GIVE BRIANLIEST
Answer:
Yes, this is a right triangle.
Step-by-step explanation:
The Pythagorean Theorem states that if the sum of the squares of the two small sides of a triangle add up to the square of the longest side, then the triangle is a right triangle: a² + b² = c², where a and b are the smallest sides (called legs) and c is the longest side (called the hypotenuse).
Here, the two smallest sides are 10 and 49.5, so let's square them, add them up, and see if they add up to 50.5²:
10² = 100
49.5² = 2450.25
100 + 2450.25 = 2550.25
50.5² = 2550.25
Since 10² + 49.5² equals 50.5², we know that this is a right triangle.
Thus, yes, this is a right triangle.

A basket contains five apples and seven peaches. You randomly select one piece of fruit and eat it. Then you randomly select another piece of fruit. The first piece of fruit is an apple and the second piece is a peach.
show work plz thanks!
Theoretical Probability Compound Events
Answer:
5/33
Step-by-step explanation:
five apples and seven peaches = 12 total
P( apple) = number of apples / total
= 5/12
No replacement since you ate it
four apples and seven peaches = 11 total
P( peach) = number of peach / total
= 4/11
P(apple, no replacement, peach) = 5/12 * 4/11 = 5/33
A line is parallel to y = 5x + 9 and
intersects the point (-2, -3). What is the
equation of this parallel line?
y = 5x + [?]
Answer:
y = 5x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 5x + 9 ← is in slope- intercept form
with slope m = 5
Parallel lines have equal slopes, thus
y = 5x + c ← is the partial equation
To find c substitute (- 2, - 3) into the partial equation
- 3 = - 10 + c ⇒ c = - 3 + 10 = 7
y = 5x + 7 ← equation of parallel line

Can you make 142? Numbers given: 2,9,1,7,2,7,5 Using any combination the numbers above and any operations, get the total to be 142. You need to give me at least 4 different ways. You also need to show me how you know your answer is correct. Only one answer can only use two steps, all the rest must have at least three steps. You have to attempt more than just one operation.
Answer:
1) 2 × 2 × 5 × 7 + 9 -7×1 = 142
2) 9 × 7 × 2 + 5 × 2 + 7 - 1 = 142
3) 2 × 9² - 7 - 7 - 5 - 1 = 142
4) 2 × 7² + 9 + 7 × 5 × 1 = 142
Step-by-step explanation:
1) 2 × 2 × 5 × 7 + 9 -7×1 = 142
Multiply 2 by 2 by 5 by 7 add to 9 then subtract 7 multiplied by 1
2) 9 × 7 × 2 + 5 × 2 + 7 - 1 = 142
Multiply 9 by 7 by 2 by 7 add to 5 multiplied by 2 then add to 7 and subtract 1
3) 2 × 9² - 7 - 7 - 5 - 1 = 2 × 9² - (7 + 7 + 5 + 1) = 142
Multiply 2 by 9 raised to the power of 2 then subtract the sum of 7, 7, 5 and 1
4) 2 × 7² + 9 + 7 × 5 × 1 = 142
Multiply 2 by 7 raised to the power of 2 then add 9 and add 7 multiplied by 5 multiplied by 1.
Solve the equation for x.
4x + ax = 2(bx + 3)
Answer:
x = [tex]\frac{6}{4+a-2b}[/tex]
Step-by-step explanation:
Given
4x + ax = 2(bx + 3) ← distribute parenthesis
4x + ax = 2bx + 6 ( subtract 2bx from both sides )
4x + ax - 2bx = 6 ← factor out x from each term on the left side
x(4 + a - 2b) = 6 ← divide both sides by (4 + a - 2b)
x = [tex]\frac{6}{4+a-2b}[/tex]
