Answer: x < 5, see attached
Step-by-step explanation:
To solve for x, we will isolate the given variable.
Given:
[tex]\displaystyle 1 > \frac{x}{5}[/tex]
Multiply both sides of the equation by 5:
[tex]\displaystyle5 > x[/tex]
Flip equation:
[tex]\displaystyle x < 5[/tex]
To graph, we will first plot a point on 5 with an open circle. Then, we will shade to the left since x is less than 5. See attached.

If m varies jointly as p and the square root of w and m=21 when p=5 and w=36, find m when p=9 and w=225
When p = 9 and w = 225, the value of m is 94.5
How to find the value of m?We know that m varies jointly as p and the square root of w, then we can write.
m = k*p*√w
Where k is a constant.
We know that m=21 when p=5 and w=36, replacing that we will get:
21 = k*5*√46
21 = k*30
21/30 = k
7/10 = k
Then the equation is:
m = (7/10)*p*√w
Then when p = 9 and w = 225 we will have:
m = (7/10)*9*√225

Three cakes are sliced into 20 pieces each. Each cake contains 1 gold ring What is the
probability one person who eats one piece of cake from each of the 3 cakes will find 3 gold
rings?
Answer:
1/60
Step-by-step explanation:
For each cake, there is a 1/20 chance to find the gold ring since it is in one of the 20 slices. The probability for each cake is independent of each other, so we multiply
1/20 x 1/20 x 1/20
=1/60
Triangle LMN is an obtuse triangle with l = 6, n = 8.3, and m∠M = 132°. What is the area of ΔLMN?
The area of triangle LMN is 49.61 square units.
We have,
To find the area of triangle LMN.
Area = (1/2) x base x height
where the base and height are the sides of the triangle perpendicular to each other.
First, we need to find the length of side L.
We can use the Law of Cosines.
L² = M² + N² - 2MNcos(132°)
L² = 6² + 8.3² - 268.3cos(132°)
L² = 36 + 68.89 + 99.36
L² = 204.25
L = √204.25
L = 14.28
Now that we know the length of the base of the triangle, we can find the height by dropping a perpendicular from vertex M to side LN.
Since triangle LMN is obtuse, the perpendicular will fall outside of the triangle.
Let's call the foot of the perpendicular point P.
Since M∠M is 132°, we can find the measure of the acute angle ∠LMP:
M∠LMP = 180° - M∠M
M∠LMP = 180° - 132°
M∠LMP = 48°
We can use trigonometry to find the length of MP:
tan(48°) = h/6
h = 6 x tan(48°)
h = 6.93
The area of triangle LMN is:
Area = (1/2) x base x height
Area = (1/2) x 14.28 x 6.93
Area ≈ 49.61
Thus,
The area of triangle LMN is 49.61 square units.

Lily Starbright, a singer-songwriter, released her first album at the beginning of March. By the
end of March, she had sold 1,040 copies. In April, she sold 1,352 copies. Several of the songs
on the album are now trending, so Lily expects her sales to continue to increase.
Write an exponential equation in the form ya(b) that can model the expected monthly
number of albums sold, y, x months after release.
Answer: 1040
Step-by-step explanation: y=ab
The exponential equation is: y = 1040(1.3^x)
How to solve
Calculate the value of y, which stands for the albums sold, and x represents the months passed from their release. For an exponential equation structured as y = a(b^x), identify the base b to solve it mathematically.
By analyzing the last month after launch, known as March, 1040 copies were made available for public consumption. One month further down the line, in April, the gross profit jumped up to 1352 units sold.
When we divide the copies traded throughout April by those resold in March, the value identifies the base:
b=1352/1040 ≈ 1.3
Thus, applying the coefficient a for the initial sales registered during March - totaling 1,040 copies - leads us to define the following form for our equations:
y = 1040(1.3^x)

Happy Motor® wants to create a database to keep track the orders to improve the
purchase and deliver process.
Each vehicle requires at least one or more different specific components, and each
department makes order to buy the components from the vendors. The vendors may
provide more than one type of the components.
All the orders are handled by the purchasing department. Each order may contain of
several different components, but all components should be come from the same vendor.
The quantity for each component requested may be different If the components needed
by the department are come from different vendors, the department need to place one
order per vendor. Each component is provided by a specified vendor.
To provide the frequently requested components immediately, an inventory is
maintained. That means the quantity on hand (QOH) for each component is recorded.
When an order comes in, it is checked to determine whether the requested component
is in inventory. If a component is not in inventory, it must be ordered from a vendor.
For each department, department code, name and email are recorded. For each order,
order number, date and total amount are recorded. For each component, component
code, name and price are recorded. Some components may not have been ordered by
any departments yet. For each vendor, vendor code, name and email are recorded. Some
vendors are newly introduced and has no order or component provided.

Each vendor provides one or more types of components
Each order contains several different components, but all components should be from the same vendor
Each component is provided by a specified vendor
An inventory is maintained to keep track of the quantity on hand (QOH) for each component
Based on these relationships, we can create an ERD with the following entities and relationships:
Department (department code, name, email) with a one-to-many relationship with Vehicle Type
Vehicle Type (vehicle type code, name) with a many-to-many relationship with Component
Component (component code, name, price) with a many-to-one relationship with Vendor
Vendor (vendor code, name, email) with a one-to-many relationship with Component and Order
Order (order number, date, total amount) with a many-to-many relationship with Component
To show the inventory relationship, we can add an attribute to the Component entity for QOH.
Note that this is just a general outline of the ERD, and there may be additional details that need to be considered based on the specific requirements of Happy Motor's purchasing department.

Lois is planning to retire from her job. She has been working there for 27 years. If she retires this year, her monthly pension will be calculated with a flat benefit formula using the flat amount of $52 for each year of
service. She was informed that if she works another 4 years that the flat amount would increase to $60 for each year of service. How much more would her pension be if she waited the 4 years?
If Lois is retiring from her job after 27 years, then if she waited for 4 years, her pension will be $38 higher than if she retires this year.
If Lois retires this year, the flat-amount is $52, So, her monthly pension can be calculated as follows;
⇒ Monthly pension = (52 × 27)/12,
⇒ Monthly pension = $117,
If Lois works for another 4 years, the flat amount used to calculate her monthly pension will increase to $60 for each year of service.
So, her monthly pension will be calculated as follows:
⇒ Monthly pension = (60 × 31)/12,
⇒ Monthly pension = $155,
So, The difference in monthly pension between retiring this year and retiring after working another 4 years can be calculated as follows:
⇒ Difference in monthly pension = $155 - $117,
⇒ Difference in monthly pension = $38,
Therefore, if Lois waits another 4 years before retiring, her monthly pension will be $38 higher than if she retires this year.

SignsWe notice the signs of each of the coordinates of ABC have been reversed for the coordinates A'B'C'. For example, A(-2, -7) became A'(2, 7).
A line joining these points is a straight line through the origin. The measure of its angle at the origin is 180°. This is the angle of rotation of A'B'C' with respect to ABC.
The image is created by 180° clockwise rotation, choice D.

Where the information relating to the circle and its diameter are given, the equation of the circle would be: "(x 5)² + y2 = 81" (Option B)
Why is this so?The above is determined by the standard form equation of a circle which is:
(x- h) ² + (y - k)² = r²
Here,
(h, k) is the center of the circle and r is the radius
In this case, the center is (-5 , 0) and the diameter is 18, so the radius is half the diameter, whic is 18/ 2 = 9
So making the required substitutions, the expression becomes:
(x-(-5))² + (y-(0))² = 9²
Which becomes
