Answer:
3x+4x-1+x+2=73
8x+1=73
8x=73-1
8x=72
8x/8=72/8
x=9
Perimeter (p) of a triangle:
[tex]p = a + b + c[/tex]
P = 73 units
To find the value of x
[tex]73 = 3x + 4x - 1 + x + 2[/tex]
→[tex]73 = 8x + 1 \\ 73 - 1 = 8x[/tex]
→[tex]8x = 72[/tex]

Find the dimensions of a rectangle given that its perimeter is 80 cm and its length is 1 cm more than twice its width.
Set up your solution using the variables L for the length, W for the width, and P for the perimeter.
Part a: Using the definition of perimeter, write an equation for P in terms of L and W .
Part b: Using the relationship given in the problem statement, write an equation for L in terms of W .
Solve the equations from parts a and b.
Answer:
The length should equal 27.
The width should equal 13.
A: P= 2L+ 2W
B: L=2W+1
Step-by-step explanation:
Perimeter is always equal to all of the sides added up.
You can find out the width and length by subsititution.
80=2(2W+1) +2W
80=4W+2+2W
80=6W+2
78=6W
W=13
L=(13*2)+1
L=27

Answer:
[tex]\dfrac{4+\sqrt{3}}{4}-\dfrac{(3+4\sqrt{3})}{12}i[/tex]
Step-by-step explanation:
Given expression:
[tex]\dfrac{4+\sqrt{3}}{3+\sqrt{-3}}[/tex]
[tex]\textsf{Apply radical rule}:\quad \sqrt{-a}=\sqrt{a}\sqrt{-1}[/tex]
[tex]\implies \dfrac{4+\sqrt{3}}{3+\sqrt{3}\sqrt{-1}}[/tex]
[tex]\textsf{Apply imaginary number rule}:\quad \sqrt{-1}=i[/tex]
[tex]\implies \dfrac{4+\sqrt{3}}{3+\sqrt{3}i}[/tex]
Multiply by the conjugate of the denominator:
[tex]\implies \dfrac{4+\sqrt{3}}{3+\sqrt{3}i} \cdot \dfrac{3-\sqrt{3}i}{3-\sqrt{3}i}[/tex]
[tex]\implies \dfrac{(4+\sqrt{3})(3-\sqrt{3}i)}{(3+\sqrt{3}i)(3-\sqrt{3}i)}[/tex]
[tex]\implies \dfrac{12-4\sqrt{3}i+3\sqrt{3}-\sqrt{3}i\sqrt{3}}{9-3\sqrt{3}i+3\sqrt{3}i-\sqrt{3}i\sqrt{3}i}[/tex]
[tex]\implies \dfrac{12+3\sqrt{3}-4\sqrt{3}i-3i}{9-3i^2}[/tex]
[tex]\implies \dfrac{12+3\sqrt{3}-(3+4\sqrt{3})i}{9-3i^2}[/tex]
[tex]\textsf{Apply imaginary number rule}:\quad i^2=-1[/tex]
[tex]\implies \dfrac{12+3\sqrt{3}-(3+4\sqrt{3})i}{9-3(-1)}[/tex]
[tex]\implies \dfrac{12+3\sqrt{3}-(3+4\sqrt{3})i}{12}[/tex]
Separate the fractions:
[tex]\implies \dfrac{12+3\sqrt{3}}{12}-\dfrac{(3+4\sqrt{3})i}{12}[/tex]
Simplify:
[tex]\implies \dfrac{4+\sqrt{3}}{4}-\dfrac{(3+4\sqrt{3})}{12}i[/tex]
Just like Earth, other planets have
seasons. In fact, Neptune's seasons last
for 40 years! How many days would
winter last? (Hint: A year is 365 days).
Winter would last for 14,600 days
How to calculate the number of days that winter would last ?Planet can be described as celestial bodies that move around the sun. The earth and Neptune are typical examples of planets. There are 8 planets in the solar system.
Other planets have different seasons same way as Earth
Neptune's season last for 40 years
Therefore the number of days that winter would last can be calculated by multiplying the number of years which is 40 by the number of days in a year which is 365
1 year is 365 days
Since it 40 years then we multiply by 365
= 365 × 40
= 14,600
Hence Winter would last for 14,600 days

Translate the sentence into an equation.
Five times the sum of a number and 3 equals 7.
Use the variable x for the unknown number.
Answer:
(5x) + 3 = 7
Step-by-step explanation:
Times means 'The answer when you multiply' So we are working in multiplication. ( x )
5x is the multiplication.
It says 'and' which can also mean addition. So we add 3. So far our equation is: (5x) + 3 (Brackets are needed as we are multiplying 5 by x and not multiplying 5 by x+3)
Lastly it says the answer must be 7 so we add that at the end. So the answer is:
(5x) + 3 = 7

If the bank is charging customers 9.75 percent APR, how much would it be willing to lend the business owner?
The amount will be $141647.55.
we need to use the present value of an annuity formula:
the formula used to determine the present value factor of an annuity is:
present value annuity factor = [1 - 1/(1 + i)ⁿ ] / i
we must divide this into 2 parts:
the first part will deal with the $19,00 monthly payment
the second part deals with the $38,000 monthly payment
i = 9.75% / 12 = 0.8125%
n (first part) = 36
n (second part) = 24
the PV annuity factor for first part = [1 - 1/(1 + 0.8125%)³⁶ ] / 0.8125% = 31.1043
the PV annuity factor for second part = [1 - 1/(1 + 0.8125%)²⁴ ] / 0.8125% = 21.7251
loan = ($219,00 x 31.1043) + ($38,00 x 21.7251)//(1 + 0.8125%)³⁶ = $59092.17 + $82555.38 = $141647.55

What is the linear speed in miles per hour of the tip of a lawnmower blade spinning at 2800 revolutions per minute in a lawnmower that cuts a path that is 26 inches wide?
What is the angular speed in degrees per hour?
The linear speed in miles per hour of the tip of a lawnmower blade spinning is 0.0601509076 miles per hour and angular velocity is 293.276 rad/hr.
What is linear speed?The measurement of a moving object's actual distance traveled is called linear speed. Linear speed is the rate of motion of an item along a straight line. It is the distance traveled along a linear path in the allotted amount of time.
2800 rotations per minute on a lawnmower blade.
Specifically, the frequency of the blade is 2800 revolutions per hour,
f = 2800 / 60, or 46.66.
The angular velocity is
ω = 2πf
where f = frequency
ω = 2 × 3.14 × 46.7
ω = 293.276 rad/hr
The diameter of the circle centered at the blade's middle determines the path's breadth.

Step-by-step explanation:
Relative frequency of an event = Event Frequency/Total Frequency
In this case the event is the number of responses for each reason and the total frequency is the sum of all responses.
Total Responses = 583 + 620 + 187 + 163 + 558 + 645 + 439 = 3195
(a) What is the relative frequency for the reason "study hard"?

Solve for x on the triangle
The value of x in given diagram is x=3;
The entire area filled by a triangle's three sides on a two-dimensional plane is referred to as the triangle's area. The fundamental equation for a triangle's area is A = 1/2 b h, where b and h are the product of the triangle's base and height. All triangle shapes, including scalene, isosceles, and equilateral triangles, may be calculated using this formula. It is important to keep in mind that a triangle's base and height are perpendicular to one another.
Area of triangle SXY = 1/2 × SX × (x-2);
Area of triangle STR = 1/2 × ST × (x+3);
Area of trapezium XTRY = 1/2 × (x+3+x-2) × XT;
Area of triangle SXY = Area of triangle STR - Area of trapezium XTRY;
SX × (x-2) = ST × (x+3) - (2x + 1) × XT;
As; SX = TX = ST/2;
(x-2)/2 = (x+3) - (2x+1)/2;
x - 2 = 2x + 6 -2x -1
x = 3;

The missing coordinate of the ordered pair (-4, m) for the equation 6x - 4y = 9 is -33/4.
Let the missing ccordinate of the ordered pair be m.
According to the given question.
We have an equation 6x - 4y = 9.
Here, we have given a ordered pair (-4, ?) which satisfy the given equation 6x - 4y = 9.
Therefore, the missing coordinate of the ordered pair (-4, m) for the equation 6x - 4y = 9 is given by
6x - 4y = 9
⇒ 6(-4) - 4(m) = 9
⇒ -24 - 4m = 9

how does this trick work? why does it always give the correct date of birthday?
The expression can be simplified to:
x + y/100
Where x is the month and y the day. This is why it always works.
Why does the trick always work?Let's define the two variables x and y as the month of your birth and the day of your birth respectively.
Now let's write the expression by following the steps, you should get:
((((7*x - 1)*13 + y + 3)*11 - x - y)/10 + 11)/100
Now let's simplify the expression we will get:
((((7*x - 1)*13 + y + 3)*11 - x - y)/10 + 11)/100
(((91x - 13 + y + 3)*11 - x - y)/10 + 11)/100
(((91x - 10 + y)*11 - x - y)/10 + 11)/100
((1001x - 110 + 11y - x - y)/10 + 11)/100
(( 1000x - 110 + 10y)/10 + 11)/100
You already can see what will happen here:
(( 1000x - 110 + 10y)/10 + 11)/100
(100x - 11 + y + 11)/100
(100x + y)/100 = x + y/100
So the expression will do the exact same thing for every values of x and y that you decide to use, it does not depend on your exact date of birthday.

What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
Market research was undertaken to determine whether an ad campaign was successful for the software company.
Total number of people = 15 + 75 = 90
The number of people who said yes = (2/5)90 = 36
The number of people who said no = 90 - 36 = 54
The number of men said yes = (6/15)x15 = 6
The number of men said No = 15 - 6 = 9
The number of women who said no = 54 - 9 = 45
Percentage = (45/90)x100
The percentage of women who said ‘no’ out of the total survey population:
