A miner earns a wage of $28.42 per hour, plus an allowance of $9.97 per hour for working underground in confined spaces. If the miner works from 8.30am to 4.00pm each day from Monday to Friday, calculate his yearly income
Answer:
$74,860.50
Step-by-step explanation:
Wages per hour = $28.42
Allowance per hour = $9.97
8.30am to 4.00pm = 7.5 hours
Per day income (24 hours) = 7.5 * $28.42 + 7.5 * $9.97
= $213.15 + $74.775
= $287.925
Weekly income (Monday - Friday) = 5 days * $287.925
= $1,439.625
There are 52 weeks in a year
Yearly income = 52 weeks * $1,439.625
= $74,860.50
His yearly income = $74,860.50

The coordinates of quadrilateral ABCD plotted on a coordinate plane are A(0, 3), B(3,-1).
C(-4, -3) and D(-7, 1). what is the perimeter of the quadrilateral?
Answer:
24.56 (parallelogram)
Step-by-step explanation:
4 sides of ABCD: AB, BC, AD, DC
perimeter = AB + BC + AD + DC
distance of two points: √(x-x')²+(y-y')²
AB = √3²+4² = √25 = 5
BC = √7²+2² = √53 = 7.28
AD = √7²+2² = √53 = 7.28
DC = √3²+4² = √25 = 5
P = 5*2 + 7.28*2 = 24.56
The perimeter of the quadrilateral = 24.56 units.
What are Quadrilateral's?A closed polygon with four sides, four vertices, and four angles is known as a quadrilateral. By joining four non-collinear points, it is formed. The amount of inside points of quadrilaterals is consistently equivalent to 360 degrees.
Given coordinates of quadrilateral ABCD, A(0, 3), B(3,-1).
C(-4, -3) and D(-7, 1)
for coordinate plane the length of a side is given by
d = √((x₂ - x₁)² + (y₂- y₁)²)
where d is the length of a side of a quadrilateral
AB = √((3 - 0)² + (-1-3)²)
AB = 5
BC = √((-4 -3)² + (-3 +1)²)
BC = √53 = 7.28
CD = √((-7 + 4)² + (1 + 3)²)
CD =5
DA = √((0+ 7)² + (3 - 1)²)
DA = √53 = 7.28
Perimeter of quadrilateral is given by sum of all the sides
= AB + BC + CD +DA = 5 + 7.28 + 5 +7.28
perimeter = 24.56 units
Hence perimeter = 24.56 units

Explain, in writing, the steps in graphing and finding the solution to the system of equations.
y = x + 2
y=-x-2
Answer:
Feel free to copy and paste:
Use the slope-intercept form to find the slope and y-intercept. To do this, use y=mx+b. Plug the variables where m=1 and b=2. Slope of the line is m and y-intercept is value of b, so the slope is 1 while the y-intercept is (0,2). Any line can be graphed using two points, and using two x values to plug them into the equation to find the corresponding y values: 0=x+2 is (-2,0). Y-intercept is already known, so use the known values and make a table where x= -2,0 and y = 0,2. Now, graph the line using the slope, y-intercept, and known points (-2,0), (0,-2) to plot the graph. Coincidingly, the answer to solve your system of equations will be the x-intercept: (-2,0).

Answer:
(13x * 10^53) + 10.
Step-by-step explanation:
To simplify the expression "13x 10^53--10" and write it using only positive exponents, we can follow these steps:
Step 1: Remove the double negative signs by converting them to positive signs:
13x 10^53 + 10
Step 2: Rewrite the expression by moving the term with a positive exponent to the denominator:
13x / (10^-53) + 10
Step 3: To simplify the denominator, we can rewrite 10^-53 as (1/10^53):
13x / (1/10^53) + 10
Step 4: Simplify the division of a fraction by multiplying by its reciprocal:
13x * (10^53/1) + 10
Step 5: Multiply 13x by 10^53:
(13x * 10^53) + 10
The simplified expression, written using only positive exponents, is (13x * 10^53) + 1
The endpoints of line segment CD are C(-2,0) and D(4,9). Find the midpoint of
line segment CD
Given:
The endpoints of line segment CD are C(-2,0) and D(4,9).
To find:
The midpoint of CD.
Solution:
Midpoint formula:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
Using the midpoint formula, the midpoint of CD is
[tex]Midpoint=\left(\dfrac{-2+4}{2},\dfrac{0+9}{2}\right)[/tex]

Fiona was thinking of a number. Fiona divides by 8, then adds 11 to get an answer of 7. What was the original number?
Answer:
-32
Step-by-step explanation:
Do the opposite of everything to fin the number:
7 - 11 = -4
-4 x 8 = -32
Check to see if it's true:
-32/8 = -4
-4 + 11 = 7
So the original number was -32, because when you divide it by 8 then add 11 it equals 7.

Answer:
$57400
Step-by-step explanation:
Given data
P= $10,000
R= 6%
T= 30 years
Let us Assume the investment is compounded Anually
A= P(1+r)^t
A=10000(1+0.06)^30
A=10000(1.06)^30
A=10000*5.74
A=$57400
Hence the Final Amount after 30 years compounded anually is $57400
