Answer:
length = 20cm
breadth = 8cm
Step-by-step explanation:
solution;
length(l) = x + 12
breadth(b) = x
perimeter (p) = 56 cm
we know that,
perimeter(p) = 2(l + b)
or, 56 = 2(x + 12 + x)
or, 56 = 2(2x + 12)
or, 56 = 4x +24
or, 56 - 24 = 4x
or, 32 = 4x
or, 32 / 4 = x
x = 8
now
putting the value of x in length and breadth
length = x+ 12
=8 + 12
=20cm
breadth = 8cm

Patrick drank 3/4 liter of water Monday before jogging. He drank 4/5 liter of water after his jog. How much water did Patrick drink altogether? (Write fraction answers as a mixed number like this 2 1/2) He drank _____ liters. *
Answer: 1¹¹/₂₀ litres
Step-by-step explanation:
The fractions need to be added.
Find a common multiple for them.
Common multiple = 20
Divide the multiple by the denominator of the fraction and multiply the numerator by the result you get:
[tex]= \frac{15 + 16}{20} \\\\= \frac{31}{20} \\\\= 1\frac{11}{20}[/tex]

3. The average of two numbers is 55. If their positive difference is 64, then determine the two numbers algebraically.
Answer:
the numbers are 41 and 23
Step-by-step explanation:
Given data
let the numbers be x and y
x+y/2= 55
cross multiply
x+y= 110----------1
positive difference is 64
x-y= 64-----------2
solve 1 and 2
x+y= 110
x-y= 64
from 1
x= 110-y
put the value of x in 2
110-y-y=64
110-2y=64
110-64=2y
46=2y
y= 46/2
y=23
put y= 23 in 2
x-23= 64
x= 64-23
x=41

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

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

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).

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.

What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
y = ( -2/3 )x - 5
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
Substituting the values in the equation , we get
Slope m = ( -2/3 )
The y-intercept b = -5
Hence , the equation of line is y = ( -2/3 )x - 5

prove 151^3-25^3 is divisible by 126
9514 1404 393
Answer:
151 -25 = 126 is a factor of the difference of those cubes
Step-by-step explanation:
The expression can be factored as ...
a^3 -b^3 = (a -b)(a^2 +ab +b^2)
151^3 -25^3 = (151 -25)(151^2 +151·25 +25^2)
= 126(151^2 +151·25 +25^2)

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
