Step-by-step explanation:
You divide 72 by the interest rate to get the number of years. Examples: For an annual rate of 8%, divide 72 by 8, for a result of 9 years. So at 8% it takes about 9 years to double your money.
A company makes spherical tanks that store chemicals. Their standard model has a diameter of 6 meters, but a customer needs a larger tank whose capacity is 2.5 times the volume of the standards model. What is the approximate diameter of this larger tank?
Answer:
[tex]V = 113.04m^3[/tex] --- Standard Model
[tex]Diameter = 15m[/tex] --- Larger Tank
Step-by-step explanation:
Given
Standard Model
[tex]Diameter = 6m[/tex]
Larger Tank
Diameter = 2.5 * Standard Model
Solving (a): Volume of Standard Model.
The tank is spherical; so, the volume (V) is as follows
[tex]V = \frac{4}{3}\pi r^3[/tex]
Where
[tex]r = \frac{1}{2}Diameter[/tex]
[tex]r = \frac{1}{2} * 6m[/tex]
[tex]r = 3m[/tex]
So:
[tex]V = \frac{4}{3}\pi r^3[/tex]
[tex]V = \frac{4}{3} * \pi * 3^3[/tex]
[tex]V = \frac{4}{3} * \pi * 27[/tex]
[tex]V = 4 * \pi * 9[/tex]
[tex]V = 4 * 9* \pi[/tex]
[tex]V = 36* \pi[/tex]
Take [tex]\pi[/tex] as 3.14
[tex]V = 36 * 3.14[/tex]
[tex]V = 113.04m^3[/tex]
Solving (b): Diameter of the larger tank
Diameter = 2.5 * Standard Model
[tex]Diameter = 2.5 * 6m[/tex]
[tex]Diameter = 15m[/tex]
Answer:
diameter =8.1

Harry is building a fish tank that is a square prism.He wants the height of the tank to be 6 inches longer than the length and the width. If s= 13 inches, what's the volume of the tank
Answer:
3042in³
Step-by-step explanation:
Volume of the square prism = Base area * Height
Since the base is a square;
Base area = s²
s is the side length of the square
Given s= 13 inches,
Base area = 13²
Base area = 169in²
If he wants the height 6 inches longer than the width and the length, then the height will be:
Height = 13 + 6 = 18 inches
Get the volume
Volume of the square prism = 169in² * 18in
Volume of the square prism = 3042in³

Solve for x: 0.75x + 3 = 6 (x - 3
I need to show my work
Answer:
x=4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
0.75x+3=6(x−3)
0.75x+3=(6)(x)+(6)(−3)(Distribute)
0.75x+3=6x+−18
0.75x+3=6x−18
Step 2: Subtract 6x from both sides.
0.75x+3−6x=6x−18−6x
−5.25x+3=−18
Step 3: Subtract 3 from both sides.
−5.25x+3−3=−18−3
−5.25x=−21
Step 4: Divide both sides by -5.25.
−5.25x/-5.25 = -21/-5.25
Answer: x=4
The value of x from the given equation is 4.
The given equation is 0.75x + 3 = 6 (x - 3).
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation can be solve for x as follows:
0.75x + 3 = 6x - 18
⇒ 6x-0.75x = 3+18
⇒ 5.25x=21
⇒ x=21/5.25
⇒ x=4
Therefore, the value of x from the given equation is 4.

Consider the absolute value inequality: |x - 6| > 20. Will the graph of the solutions to the inequality result in an "and" or an "or" inequality? Without solving to find the exact solutions, explain
Step-by-step explanation:
Case 1 : |x| > a, => x > a or x < -a
Case 2 : |x| < a, => -a < x < a
Since this question follows Case 1, we will have an "or" inequality.

Write the standard form of the equation y−6=3/4(x−5).
9514 1404 393
Answer:
3x -4y = -9
Step-by-step explanation:
Multiply by 4 to clear the fraction.
4(y -6) = 3(x -5)
Subtract the left-side term to get variables on the same side, with a positive x-coefficient.
0 = 3(x -5) -4(y -6)
Eliminate parentheses and collect terms.
0 = 3x -15 -4y +24
0 = 3x -4y +9
Subtract 9 and swap sides to get standard form.
3x -4y = -9
_____
Standard form is ...
ax +by = c
where a ≥ 0, and a, b, c are mutually prime integers. If a=0, then b > 0.

What is the value of n in the equation - {(2n + 4) + 6 = -9 +4(2n + 1)
Answer:
n = 2.5 or n = (5/2)
Step-by-step explanation:
(2n+4) +6 = -9 + 4(2n+1)
first distribute the 4 to the (2n+1)
(2n+4) +6 = -9 + (8n+4)
then add 9 to both sides to cancel out the -9 on the right side
(2n+4) +15 = (8n+4)
next subtract (2n+4) from both sides to cancel out the (2n+4) on the left side combining like terms as you subtract
15 = 6n
then divide 15 by 6 to get your final answer
n = 2.5
or
n = (5/2)

The graph of g(x) is steeper than the graph of f(x). Then the correct option is A.
What is a function?Functions are found all across mathematics and are required for the creation of complex relationships.
The graphs of f(x) = x and g(x) = f(5x).
Then the g(x) can be written as
g(x) = 5x
Then the slope of g(x) is more than the slope of f(x).
The graph of g(x) is steeper than the graph of f(x).
Then the correct option is A.

Step-by-step explanation:
Y intercept is 500 because she is starting off with $500 each month
slope is 75 because she gets $75 more every time she sells one
start at (0,500) then plot a point at (1,575) then (2,650) increasing by 75 every time x increases by 1
If you start at (0,500) you can move backwards going to (-1,425) to (-2,350) decreasing by 75 as you move backwards
the equation is y=75x+500
