Answer:
18.85 years
Step-by-step explanation:
Using the [tex]A=P(1+\frac{r}{n} )^{nt}[/tex] we can manipulate it to give us time.
However, let's identify our variables:
A is our final amount which is given to us, $1400.
P is our principle which is $500.
r is our rate which is 5.5% which can be traducted into 0.055.
n is the # of time our money get compounded per year, in this case quarterly means 4 times a year therefore n = 4.
t is time and is what we are trying to solve for.
Now let's manipulate our equation to find t:
[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]
[tex]\frac{A}{P} =(1+\frac{r}{n} )^{nt}[/tex]
[tex]\frac{1400}{500} =(1+\frac{0.055}{4} )^{4t}[/tex]
[tex]2.8=1.01375^{4t}[/tex]
[tex]log_{1.01375}(2.8)=log_{1.01375}1.01375^{4t}[/tex]
[tex]log_{1.01375}(2.8)=4t[/tex]
[tex]\frac{log_{1.01375}(2.8)}{4} =t[/tex]
[tex]18.84876253=t[/tex]
It would take about 18.85 years in order for you to accumulate at least $1400.

What did is the total volume,in cubic feet of the shape below
Answer:
64ft^3 (The ^3 is meant to be cubed) 64 feet cubed.
Step-by-step explanation:
The picture has already split the two shapes.
*Remember Volume Formula: LWH or Length times Width times Height.*
The first shape is 4ft x 2ft x 2ft
The second shape is a little bit of a fuss but it's alright.
*Talking about the length of Shape no.2*
Since the second shape is longer than the first one (by length). You need to double it meaning: 4x2 or 4+4 = 8ft
The second shape is 8ft x 2ft x 3ft
First shape should have a volume of 16ft
Second shape should have a volume of 48ft
Now, you need to add the two volumes:
48ft + 16ft = 64ft cubed

I NEED HELP ASAP!!!!!!!!!!!
Answer: Below
Step-by-step explanation:
Let's start with 12. Going off of basic quadrilateral rules, adjacent angles will be equal to 180. So we make the equation:
8x - 12 + 3x + 5 = 180
Simply.
11x - 7 = 180
11x = 187
x = 17
Since R = P, R = 3(17) + 5 = 56
Now with 14.
We know ABC is both 115 and 4x+6, so:
115 = 4x + 6
109 = 4x
x = 27.25
ADB is 6x - 11, so 6(27.5) - 11 = 152.5
12) 56
14) 152.5

Mandy paints four square walls that are ten feet on each side. Which expression represents the total square footage that Mandy painted?
4 × 102
42 × 10
4 × 10 × 2
102 + 4
Answer:
C. 4 × 10 × 2
Step-by-step explanation:
There are four walls that are ten feet on each side.
You would take 4 (number of walls) × 10 (number of feet in length), and because there are 2 sides of the walls, you would take that × 2.
Therefore, your answer is 4 × 10 ×2

A 6 foot wide painting should be centered on a 10 foot wide wall. How many feet (x) should be on each side of the painting?
Answer:
The answer would be two feet.
Step-by-step explanation:
Step 1. Do 10-6 (10 being the total space and 6 being the painting)
Step 2. Get the answer of 4.
Step 3. Divide four by 2 because it needs to be centered.
Step 4. Get the answer of two feet on each side.

A rectangular garden is 15 ft longer than it is wide. Its area is 700 ft. What are its dimensions?
Step-by-step explanation:
Given :-
The length of rectangular garden is 15 feet longer than its widthThe area of rectangular garden is 700ft²To find:-
Dimensions of rectangular gardenSolution:-
According to the question , let the length of rectangular garden be x and width be x + 15
We know , the formula for area of rectangular garden is L × B
putting the known values ,
700ft.² = X × (X + 15)
700 ft. ² = x² + 15x
x² + 15 x - 700 = 0
By factorising it we get , x = 20
So , the dimensions of rectangular garden are 20 feet and 35 feet respectively for length and width.

10. Cindy is wrapping a birthday present for her sister. The present is in a 10 points
box that has a length of 10 in, a width of 6 in and a height of 4 in. If the
wrapping paper costs $0.25 per square inch, how much would it cost to
wrap Cindy's present? *
Answer:
$648
First find the surface area, and then multiply that by 12 for the inches, then multiply that by the cost
Answer:
$62
Step-by-step explanation:
First find the surface area of the box: 2(lw+lh+wh) = 2(60 + 40 +24) = 124(2) = 248
Now create a ratio to find the total cost:
[tex]\frac{0.25}{1} = \frac{x}{248}[/tex]
Solve for x by cross multiplying -
x=62
If x²+ y²= 80 and xy = 12, find the value of (x - y)².
[tex](x-y)^2\\\\=x^2+y^2 -2xy\\\\=80-2(12)\\\\=80-24\\\\=56[/tex]

Which of these inequalities means that
18 is greater than three times a number?
Let's write this verbal phrase as an inequality.
First of all, let the number be n.
"three times n" can be written like so:-
[tex]\pmb{3n}[/tex]
Now, 18 is greater than 3n:-
[tex]\pmb{18 > 3n}[/tex]
Which means 3n is less than 18:-
[tex]\bigstar{\boxed{\pmb{3n < 18}}}[/tex]

Answer:
B
Step-by-step explanation:
x² - 8x + 97 = 0
the general form to solve such quadratic equations is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = -8
c = 97
so, we get
x = (8 ± sqrt((-8)² - 4×1×97))/(2×1) =
= (8 ± sqrt(64 - 388))/2 = (8 ± sqrt(-324))/2 =
= (8 ± sqrt(324×-1))/2 = (8 ± 18×i)/2 = 4 ± 9i
