A fraction bar labeled 1. Under the 1 are 5 boxes labeled one-fifth. Under the 5 boxes are 3 boxes containing one-third. Under the 3 boxes are 15 boxes labeled StartFraction 1 Over 15 EndFraction.
Answers
Answer:
[tex]\dfrac{5}{6}[/tex]
Step-by-step explanation:
The problem says Two-thirds divided by StartFraction 4 Over 5 EndFraction.
Two thirds means = 2/3
It means,
[tex]x=\dfrac{2}{3}\ \text{divided by}\ \dfrac{4}{5}[/tex]
or
[tex]x=\dfrac{\dfrac{2}{3}}{\dfrac{4}{5}}\\\\=\dfrac{2}{3}\times \dfrac{5}{4}\\\\=\dfrac{5}{6}[/tex]
Hence, the required answer is [tex]\dfrac{5}{6}[/tex].

Answer:

Answer:
x = 2
y = 1
z = 4
Step-by-step explanation:
Step 1:
2x + y + z = 9
3x - y = z = 9
5x + 2z = 18 <-- add x and y
Step 2:
-x -y + z = 1
2x + y + z = 9
x + 2z = 10
Step 3:
-(x + 2z = 10) = -x - 2z = -10
5x + 2z = 18
-x - 2z = -10
4x = 8
x = 2
Step 4: solve for z
-x - 2z = -10 <-- Plug x
-(2) - 2z = -10
-2z = -8
z = 4
Step 5: solve for y
2x + y + z = 9
2(2) + y + 4 = 9
8 + y = 9
y = 1

Carrie and nine of her friends go out to dinner. The total bill comes to $191.10. They decide to (I leave a 15% tip. Each person will contribute an equal amount to the total tip. Estimate what each person should contribute.
$19.00
$28.50
$1.90
$2.85
Answers
Answer:
$2.85 per person
Step-by-step explanation:
$191.10 * 0.15 = $28.665 tip
total tip divide by 10 people
$28.665/10 = $2.85
Each person has to contribute $2.85 amount for the tip.
Given,
Total no. of person go out for dinner = carrie + her nine friends
= 1+9 = 10
Amount of the bill is = $191.10
Amount of tip is = 15% of the bill
= [tex]\frac{15 }{100}[/tex] × $ 191.10
= 28.665
Total amount each person contribute an equal amount for tip is = [tex]\frac{28.665}{10}[/tex]
=$ 2.85
Each person contribute $2.85 amount for the tip.

Let y 00 + by0 + 2y = 0 be the equation of a damped vibrating spring with mass m = 1, damping coefficient b > 0, and spring constant k = 2. (a) Convert this second order equation into a system of two first order equations. (b) Express the eigenvalues for this system in terms of b. (c) Describe the stability of the equilibrium solution ~0 for b > 2 √ 2. Justify your claim with information about the eigenvalues of the matrix for the system. (d) Connect the behavior of solutions near an equilibrium of this type with the spring mass system with damping coefficient b > 2 √ 2 and explain why your answer for part (c) is (or is not) what one should expect.
Answers
Answer:
Step-by-step explanation:
Given that:
The equation of the damped vibrating spring is y" + by' +2y = 0
(a) To convert this 2nd order equation to a system of two first-order equations;
let y₁ = y
y'₁ = y' = y₂
So;
y'₂ = y"₁ = -2y₁ -by₂
Thus; the system of the two first-order equation is:
y₁' = y₂
y₂' = -2y₁ - by₂
(b)
The eigenvalue of the system in terms of b is:
[tex]\left|\begin{array}{cc}- \lambda &1&-2\ & -b- \lambda \end{array}\right|=0[/tex]
[tex]-\lambda(-b - \lambda) + 2 = 0 \ \\ \\\lambda^2 +\lambda b + 2 = 0[/tex]
[tex]\lambda = \dfrac{-b \pm \sqrt{b^2 - 8}}{2}[/tex]
[tex]\lambda_1 = \dfrac{-b + \sqrt{b^2 -8}}{2} ; \ \lambda _2 = \dfrac{-b - \sqrt{b^2 -8}}{2}[/tex]
(c)
Suppose [tex]b > 2\sqrt{2}[/tex], then λ₂ < 0 and λ₁ < 0. Thus, the node is stable at equilibrium.
(d)
From λ² + λb + 2 = 0
If b = 3; we get
[tex]\lambda^2 + 3\lambda + 2 = 0 \\ \\ (\lambda + 1) ( \lambda + 2 ) = 0\\ \\ \lambda = -1 \ or \ \lambda = -2 \\ \\[/tex]
Now, the eigenvector relating to λ = -1 be:
[tex]v = \left[\begin{array}{ccc}+1&1\\-2&-2\\\end{array}\right] \left[\begin{array}{c}v_1\\v_2\\\end{array}\right] = \left[\begin{array}{c}0\\0\\\end{array}\right][/tex]
[tex]\sim v = \left[\begin{array}{ccc}1&1\\0&0\\\end{array}\right] \left[\begin{array}{c}v_1\\v_2\\\end{array}\right] = \left[\begin{array}{c}0\\0\\\end{array}\right][/tex]
Let v₂ = 1, v₁ = -1
[tex]v = \left[\begin{array}{c}-1\\1\\\end{array}\right][/tex]
Let Eigenvector relating to λ = -2 be:
[tex]m = \left[\begin{array}{ccc}2&1\\-2&-1\\\end{array}\right] \left[\begin{array}{c}m_1\\m_2\\\end{array}\right] = \left[\begin{array}{c}0\\0\\\end{array}\right][/tex]
[tex]\sim v = \left[\begin{array}{ccc}2&1\\0&0\\\end{array}\right] \left[\begin{array}{c}m_1\\m_2\\\end{array}\right] = \left[\begin{array}{c}0\\0\\\end{array}\right][/tex]
Let m₂ = 1, m₁ = -1/2
[tex]m = \left[\begin{array}{c}-1/2 \\1\\\end{array}\right][/tex]
∴
[tex]\left[\begin{array}{c}y_1\\y_2\\\end{array}\right]= C_1 e^{-t} \left[\begin{array}{c}-1\\1\\\end{array}\right] + C_2e^{-2t} \left[\begin{array}{c}-1/2\\1\\\end{array}\right][/tex]
So as t → ∞
[tex]\mathbf{ \left[\begin{array}{c}y_1\\y_2\\\end{array}\right]= \left[\begin{array}{c}0\\0\\\end{array}\right] \ \ so \ stable \ at \ node \ \infty }[/tex]

Given the numbers
10 11 12 13 14 15 16 17 18 19 20
Let 'x' be the number
The condition breakdown:
I am less than 20.
So the number 'x' must be less than 20 i.e. x < 20I am more than 13.
So the number 'x' must be greater than 13 i.e. x > 13I am less than 17.
So the number 'x' must be less than 17 i.e. x < 17Finally:
I am 4 more than 12
i.e. 12+4 = 16
Thus, the number is x = 16

x > 10I am less than 20.
x < 20I am more than 12.
x > 12I am less than 15.
x < 15As the numbers left after all the conditions are fulfilled are 13 and 14.

Answer:
4.75%
Step-by-step explanation:
When simple interest is charged, the payback amount is ...
A = P(1 +rt) . . . . for annual rate r and a term of t years
Using the given values, we can solve for r.
10280 = 8000(1 +6r)
1.285 = 1 +6r . . . . . . . . divide by 8000
0.285 = 6r . . . . . . . . . . subtract 1
0.285/6 = r = 0.0475 = 4.75% . . . . . . divide by 6; express as %
Theo paid interest at the rate of 4.75%.
