d

Given The Diagram Below, Find The Value Of X: A27.5 B62 C8.5 D31

Answers

Answer 1

Answer:

x = 31

Step-by-step explanation:

The 3 angles in a triangle sum to 180°

Sum the 3 given angles and equate to 180

2x - 7 + 2x + 63 = 180, that is

4x + 56 = 180 ( subtract 56 from both sides )

4x = 124 ( divide both sides by 4 )

x = 31

The endpoints of line segment CD are C(-2,0) and D(4,9). Find the midpoint of
line segment CD

Answers

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]

[tex]Midpoint=\left(\dfrac{2}{2},\dfrac{9}{2}\right)[/tex]

[tex]Midpoint=\left(1,4.5\right)[/tex]

Therefore, the midpoint of the line segment CD is (1,4.5).

Explain, in writing, the steps in graphing and finding the solution to the system of equations.
y = x + 2
y=-x-2

Answers

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).

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

Answers

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

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

Fiona was thinking of a number. Fiona divides by 8, then adds 11 to get an answer of 7. What was the original number?

Answers

7 - 11= -4
-4 x 8= -32
Original number was -32

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:

(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 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?

Answers

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
