what does UIF stand for ?
Answers
UIF stands for Unemployment Insurance Fund.
When workers become unemployed or are unable to work due to maternity, adoption, or parental leave, or illness, the Unemployment Insurance Fund (UIF) provides them with short-term assistance. It also helps the dependents of a deceased contributor.South Africa's unemployment insurance system is governed by the following legislation: 2001 Unemployment Insurance Act (the UI Act). 2002 Unemployment Insurance Contributions Act (the UIC Act)These Acts, which went into effect on April 1, 2002, provide for the benefits to which contributors are entitled, as well as the imposition and collection of contributions to the UIF.Contributions to the UIF are due from all employees and their employers. However, an employee is not eligible to contribute to the UIF if he or she: is employed by the employer for less than 24 hours per month; is employed as an officer or employee in the national or provincial spheres of government; or is employed as an officer or employee in the national or provincial spheres of government. Is a traditional leader, a member of the province House of Traditional Leaders, and a member of the Council of Traditional Leaders.Thus this is the full form of UIF.

Hans will run 27 miles this week. so far, he has run 18 miles. what are the possible numbers of additional miles he will run? use t for the number of additional miles he will run.
Answers
Hans will run additional 9 miles to the 18 miles he has run to complete 27 miles in wants to run for the week.
If Hans is to run 27 miles this week and he has run 18 miles, the additional miles he has to run in the week is t. Meaning that t plus eighteen is equal to 27, which is expressed mathematically below
t + 18 = 27
To solve the equation above, use balancing method. To use balancing method, subtract 18 from both side of the equation.
t +18 -18 = 27-18
t + 0 = 27-8
t = 27 -18
t = 9
Therefore, Hans will run additional 9 miles to complete 27 miles for the week.

The figure shown is composed of a triangle within
a trapezoid. Determine the area of the
shaded region.
Answers
The area of the shaded region = area of the trapezoid - area of the = 42 - 5.25 = 36.75 m²
What is the Area of a Trapezoid?Area of ay trapezoid is determined using the formula:
Area = 1/2 × (a + b) × h, where a and b are the lengths of the bases of the trapezoid that are parallel, and h is the height or distance between the bases of the trapezoid.
What is the Area of a Triangle?
To find the area of a triangle, use:
Area = 1/2 × base × height of the triangle.
The area of the shaded region = area of the trapezoid - area of the triangle
Area of the trapezoid:
a = 5 m
b = 9 m
h = 6m
Substitute
Area of the trapezoid = 1/2 × (5 + 9) × 6
Area of the trapezoid = 1/2 × (14) × 6
Area of the trapezoid = 7 × 6
Area of the trapezoid = 42 m²
Area of the triangle:
Base = 7 m
Height = 6 - 4 1/2 = 1.5 m
Substitute
Area of triangle = 1/2 × 7 × 1.5
Area of triangle = 5.25 m².
The area of the shaded region = area of the trapezoid - area of the = 42 - 5.25 = 36.75 m²

Factor this expression completely.
6x^2- 13x - 28
Answers
Answer: (2x-7)(3x+4)
Step-by-step explanation:
There is a technique called the “Slide Method” that can make this easier to solve.
The first step is to slide the coefficient of the 1st term and multiply it to the last term; which becomes:
X^2-13x-28(6) or x^2-13x-168
Next, factor this equation normally. The two factors that go into this are -21 and 8, so we can set this up as: (x-21)(x+8)
After that, divide both sides by the 6 that you previously slid:
(X-21/6)(x+8/6)
Then, reduce the fractions:
(X-7/2)(x+4/3)
After this is the last step. Take the denominator of the fraction, and make it the coefficient of the x variable: (2x-7)(3x+4)
Checking our Work; we get: (6x^2+8x-21x-28)=(6x^2-13x-28)
So, we know that (2x-7)(3x+4) is correct.

Answers
The cost spent per gallon of the gas is a $4 and the total money spent on gas is a 20$.
According to the statement
We have to find that the cost of the gas he used.
So, For this purpose, we know that the
A cost function may be a mathematical formula wont to wont to chart how production expenses will change at different output levels.
From the given information:
It costs Kobel $3.50 in tolls to drive to figure and back day after day, plus he uses 5 gallons of gas. It costs him a complete of $23.50 to drive to figure and back daily.
Then
Total money he spent = Toll cost + amount of gas she used
$23.50 = $3.50 + 5 gallons
Then
Cost of the 5 gallons = 23.50 - 3.50
Cost of the 5 gallons = 20
Then
cost of the 1 gallon gas = 20/5
cost of the 1 gallon gas = $4.
So, The cost spent per gallon of the gas is a $4 and the total money spent on gas is a 20$.

Answers
Given - Sides of a triangle
Find - Value of x
Solution - The value of x is 3.
The sides of the right angled triangle are calculated by the Pythagoras theorem. As per the theorem,
Hypotenuse² = Base² + Perpendicular²
In the given triangle, Hypotenuse is (x+2), Perpendicular is 5 and Base is (x-3).
(x+2)² = 5² + (x-3)²
x² + 4x + 4 = 25 + x² - 6x + 9
On solving, the equation will be -
6x + 4x = 25 + 9 - 4
Performing addition and subtraction to find the value of x
10x = 30
x = 30/10
Performing division to find the value of x
x = 3
So, the value of x is 3.
