We are asked to find the solution to the inequality:
[tex]\star~\large\pmb{\cfrac{x}{9}+3 < 4}[/tex]
[tex]\triangle~\fbox{\bf{KEY:}}[/tex]
First, subtract 3 from both sides, then multiply both sides by the denominator.Step 1.
[tex]\star~\large\pmb{\cfrac{x}{9} < 4-3}[/tex]
[tex]\star~\large\pmb{\cfrac{x}{9} < 1}[/tex]
Step 2.
[tex]\star~\large\pmb{\cfrac{x}{9}\times9 < 1\times9}[/tex]
Notice that on the left, the 9s cancel, and we're left with x.
Step 3.
[tex]\star~\large\pmb{x < 9}[/tex]
This is the solution.
Hope it helps you out! :D

Answer:
x < 9
Step-by-step explanation:
Given:
[tex]\dfrac{x}{9} + 3 < 4[/tex]
1. Subtract 3 from both sides of the inequality
[tex]\dfrac{x}{9} + 3 - 3 < 4 - 3\\\\\implies\dfrac{x}{9} < 1[/tex]
2. Multiply both sides of the inequality by 9
[tex]9\left(\dfrac{x}{9}\right) < 1(9)\\\\\implies x < 9[/tex]

The probability that a morning bus arrives on time is 65%.
a Draw a tree diagram showing all the possible outcomes for three
consecutive mornings.
The attached diagram represents the tree diagram for three consecutive mornings.
How to draw the tree diagram?The probability of arriving on time is given as:
P(On Time) = 65%
Assume that the bus would definitely show up.
Then it means that the event is a binomial event and the possible outcomes are:
On Time and Late
The above means that the number of possible outcomes is 2.
For three consecutive mornings, the total outcome is:
Total = 2³
Evaluate
Total = 8
This means that the tree diagram would have 8 outcomes
Next, we draw the tree diagram (see attachment)

Problem 9
r+h = 9
SA = 2*pi*r^2 + 2*pi*r*h = 54pi
2*pi*r^2 + 2*pi*r*h = 54pi
2pi*r(r + h) = 54pi
r(r+h) = 27
r(9) = 27
9r = 27
r = 27/9
r = 3
r+h = 9
h = 9-r
h = 9-3
h = 6
Answers: r = 3 and h = 6 are the radius and height respectively.
==========================================================
Problem 10
d = diameter = 68 mm
r = radius = d/2 = 68/2 = 34 mm
SA = surface area of a sphere
SA = 4*pi*r^2
SA = 4*pi*34^2
SA = 4264pi
Answer: 4264pi square mm
==========================================================
Problem 11
Plug V = 3000 into the sphere volume formula and isolate r.
V = (4/3)pi*r^3
3000 = (4/3)pi*r^3
(4/3)pi*r^3 = 3000
4pi*r^3 = 3*3000
4pi*r^3 = 9000
r^3 = 9000/(4pi)
r = cube root( 9000/(4pi) )
r = ( 9000/(4pi) )^(1/3)
r = 8.947002 approximately
Now we can determine the surface area of this sphere.
SA = 4pi*r^2
SA = 4*pi*( 8.947002 )^2
SA = 1005.923451
Answer: 1005.923451 square feet approximately
==========================================================
Problem 12
We'll follow the same idea as problem 11, but in reverse.
SA = 4*pi*r^2
400pi = 4pi*r^2
r^2 = (400pi)/(4pi)
r^2 = 100
r = sqrt(100)
r = 10
Luckily we get a nice whole number for the radius r. Use it to find the volume.
V = (4/3)*pi*r^3
V = (4/3)*pi*10^3
V = (4000/3)pi
Answer: (4000/3)pi cubic inches exactly
==========================================================

preferred stock common stock
(dividends per share) (dividends per share)
20y1
20y2
20y3
Based on the preferred dividends, the dividends for preferred and common stock in each year are:
Preferred stock dividends:
20y1 - $3.00 per share.20y2 - $1.20 per share.20y3 - $4.80 per share.Common stock dividends:
20y1 - $1.20 per share.20y2 - $0 per share.20y3 - $1.68 per share.What are the preferred dividends?Preferred shares have a specific dividend, and as these are cumulative shares, the dividends that are not paid in one year, will be paid in the next.
Dividends per year:
= 20,000 x 2% x 150
= $60,000
20y1 dividend per share:
= 60,000 / 20,000
= $3.00 per share
20y2 dividend per share:
= 24,000 / 20,000
= $1.20 per share
20y3 dividend per share:
The remaining dividend from 20y2 will have to be paid here:
= (60,000 + (60,000 - 24,000)) / 20,000
= 96,000 / 20,000
= $4.80 per share
What are the common dividends?Preferred dividends are paid first:
Common dividends are:
= (Amount distributed as dividends - Preferred dividends) / Number of common shares
In 20y1:
= (120,000 - 60,000) / 50,000
= $1.20
In 20y2:
= (45,000 - 45,000) / 50,000
= $0 per share
In 20y3:
= (180,000 - 96,000) / 50,000
= $1.68 per share.

Step-by-step explanation:
The sum of the INTERior angles of a pentagon equal
(n-2)(180) = 540
each angle is then 540/5 = 108
each is a supplementary angle to the exterior angle
so EACH exterior angle is 180 - 108 = 72
