Answer:
a) is not a triangle.
b)
Okay, so I used this method to determine if the measurements will make a triangle.
a+b has to be greater than c. 7+2= 9. So 9 is greater than c
a+c has to be greater than b. 7+ 5= 12. which is greater than b
c+b has to be greater than a. 5+ 2 is 7. which is equal to a.
That means it would not make a triangle. Because c+b must be GREATER than a.
Consider doing the 2nd one the way I did the first question.

Problem 1
w = width
w+36 = length, because it's 36 feet longer compared to the width
=======================================================
Problem 2
The area w(w+36) is less than 2040, and it's also larger than 0.
We can write that as [tex]0 \le w(w+360) \le 2040[/tex] which is the same as [tex]0 \le w^2+360w \le 2040[/tex]
If you wanted to drop the first part, then you can say either [tex]w(w+360) \le 2040[/tex] or [tex]w^2+360w \le 2040[/tex]
I used the formula area = length*width
=======================================================
Problem 3
There are many possibilities here. Let's say w = 10 feet. If so then the length would be w+36 = 10+36 = 46 feet. This 10 by 46 rectangle has an area of 10*46 = 460 square feet which is under the 2040 sq ft limit.
Another possibility is that w = 20 ft and w+36 = 56. This 20 by 56 rectangle has an area of 20*56 = 1120 sq ft.
It turns out you can pick any value of w between 1 and 30, assuming you only restrict yourself to integers. You can find the largest possible value of w by solving the equation w(w+36) = 2040. The positive solution to this equation is roughly w = 30.62
Side note: even though something like w = 1 is possible, it's not very realistic. A conference hall that's only 1 ft wide won't be able to fit a person comfortably unless they don't mind being sandwiched between two walls and have to walk sideways.
=======================================================
Problem 4
If you solved w(w+36) = 360 with a graphing calculator or the quadratic formula, then you would find the positive solution for w is roughly 8.15
If your teacher is considering positive real numbers, then this is realistic; however, if they are only considering positive integers, then something like w = 8.15 isn't possible.

1) The ratio of the number of boys to the number of girls at a school is 4:5. If there are 120 boys, how many students are there altogether?
A 53 C 150
B 96 D 270
Answer:
270 students all together. First you divide 120 by the ratio of boys. That'll get you 30, then multiply 30 by 5 which is the girls ratio and you'll get 150. Finnaly add 150 + 120 then boom your answer

A rectangular garden measures 8 x 6 meters. It is desired to remove part of the garden to install a uniform sidewalk of witdh (x) around of such garden. The surface of the new garden must be 1/6 of the old garden. Determine the witdh (x) of the sidewalk of the new garden.
(Using quadratic formula)
The width of the sidewalk is 1.155.
What is a rectangle?A rectangle is a type of parallelogram having equal diagonals.
All the interior angles of a rectangle are equal to the right angle.
The diagonals of a rectangle do not bisect each other.
Given that,
The dimension of the rectangular garden is 8 x 6.
The surface of the new garden is 1/6 th of the original one.
Suppose the width of the side walk is x.
Then, the dimensions of the sidewalk is given as (8 - 2x) x (6 - 2x).
As per the question the following equation can be written for the area of new garden,
(8 - 2x) x (6 - 2x) = (1/6) (8 x 6)
=> 48 - 4x²- 30x = 8
=> 4x² + 30x - 40 = 0
Solve the above quadratic equation to get,
x = -8.655, 1.155
Since the width cannot be negative, the value of x is taken as 1.155.
Hence, the width of the sidewalk of the new garden is 1.155m.

How do you solve this? :)
Answer:
x = -2
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& Roots)
Multiplications
Divisions
Additions
Subtraction

First, subtract 7 from both sides of the equation:
6x + 7 = -5
6x + 7 (-7) = -5 (-7)
6x = -5 - 7
6x = -12
Next, isolate the variable, x, by dividing 6 from both sides of the equation:
(6x)/6 = (-12)/6
x = -12/6
x = -2
x = -2 is your answer.

The temperature of a city doubles during the day. It then decreases by 12.1ºF after the sun goes down. The temperature at the end of the day is −6.5°F.
What was the temperature at the beginning of the day?
(This is a question on k12)
the answer is 5.6
because 5.6-12.1=-6.5 which is the temperature at the end of the day
hope this helps I really take my time to do this:)
Answer:
The answer is 2.8
Step-by-step explanation:
Since the temperature at the end of the day is -6.5.
So you add 12.1ºF to -6.5 and you get 5.6.
5.6 is the temperature throughout the day.
The question asks for the temperature from
the start of the day and the question says it
doubles throughout the day. Therefore,
divide 5.6 by 2 which gets you 2.8.

Krista has a pocket full of nickels and quarters that makes $3.55. If she has a total of 27 coins in her pocket, how many are nickels and how many are quarters?
Answer:
Look down
Step-by-step explanation:
Two equations
x = Quarters
y = Nickles
25x + 5y = 355 -- 1
x + y = 27 -- 2
5x + 5y = 135 -- 2
20x = 200
x = 10
sub in 2
10 + y = 27
y = 17
x = 10
Quarters equal 10
∠A and \angle B∠B are supplementary angles. If m\angle A=(8x-25)^{\circ}∠A=(8x−25) ∘ and m\angle B=(7x-5)^{\circ}∠B=(7x−5) ∘ , then find the measure of \angle B∠B.
An38
Step-by-step explanation:
The measure of angle B is 93°
Here,
∠A and ∠B are supplementary angles.
∠A = (8x - 25)° and ∠B = (7x - 5)°
We have to find ∠B.
What are Supplementary angles?
Two Angles are Supplementary when they add up to 180 degrees.
Now,
∠A and ∠B are supplementary angles.
Hence, ∠A + ∠B = 180°
Here, ∠A = (8x - 25)° and ∠B = (7x - 5)°
Put in above equation we get;
(8x - 25)° + (7x - 5)° = 180°
15 x - 30 = 180
15 x = 210
x = 14
So, Measure of ∠B = (7x - 5)° is;
∠B = (7x - 5)° = ( 7 * 14 - 5) = 98 - 5 = 93°
Hence, The measure of angle B is 93°.

One day at central high school, 1/12 of the students were absent , and 1/5 of those present went on a field trip. If the number of students staying oin school was 704, how many students are enrolled at central high
Answer:
960
Step-by-step explanation:
If 1/12 were absent, then 11/12 were present.
If 1/5 of those were gone, then 4/5 of those were present.
(11/12)(4/5)enrollment = 704 . . . 4/5 of 11/12 of the enrollment is 704 students
(11/15)enrollment = 704 . . . . . . simplify
enrollment = 704(15/11) = 960 . . . . . multiply by 15/11
960 students are enrolled at Central High.
