Answers
Answer:
b = [tex]\frac{ac-2c}{2a}[/tex]
Step-by-step explanation:
Given
[tex]\frac{1}{2}[/tex] = [tex]\frac{1}{a}[/tex] + [tex]\frac{b}{c}[/tex]
Multiply through by 2ac to clear the fractions
ac = 2c + 2ab ( subtract 2c from both sides )
ac- 2c = 2ab ( divide both sides by 2a )
[tex]\frac{ac-2c}{2a}[/tex] = b

Given the following polygon, find the sum of the interior angles and the value of x,
pls help
Answers
Answer:
sum of interior angles - 540
x = 112
Step-by-step explanation:
Hello There!
Geometry
The sum of the interior angles can be found using this formula
let x = sum of interior angles and n = number of sides
x = ( n - 2 ) * 180
there are 5 sides so we plug in 5 to n
5 - 2 = 3
3 * 180 = 540 so the sum of the interior angles is 540
Now to solve for x
Remember the sum of the interior angles is 540 so we use this equation to solve for x
Simple Algebra
540 = x + 118 + 105 + 75 + 130
step 1 combine like terms
118 + 105 + 75 + 130 = 428
now we have 540 = 428 + x
step 2 subtract 428 from each side
540 - 428 = 112
we're left with x = 112
estimate a 20% tip for $31.15
$4.65
$3.10
$6.20
$12.40
Answers
Answer: 6.20$
Step-by-step explanation:
I am going to explain it two different ways.
31.15 x 0.20 = 6.23
31.15 +6.23 tip = 37.38 for you total bill including tip
An easier way my mom taught me for tipping in restaurants is you look at the bill $31.15 in this case move the decimal to the left one place and that give you 10%..double it and you have your 20% tip.
3.11 + 3.11 = 6.22
This way you don’t have to take a calculator out in front of anyone to calculate the tip.

The Smiths want to fence their square garden, which has an area of 289 square feet. What would be the minimum amount of fencing needed to complete the project? A) 68 feet of fencing B) 17 square feet of fencing C) 289 feet of fencing D) 17 feet of fencing
Answers
Answer:
68 feets of fencing
Step-by-step explanation:
Given that:
Area of square garden = 289 ft²
The side length of square garden can be obtained thus :
Area of a square = s²
Where s = side length
s² = 289
s = sqrt(289)
s = 17
Perimeter of square garden : 4s
Perimeter = 4* 17 = 68 feets

Step-by-step explanation:
Given
Hester get a fixed amount and an additional $15 for an extended warranty
Suppose x is the amount of fixed amount
for 15 television sale, the price is $1275

4. The Bulldog Theater charges $9.10 for each adult ticket and $7.75 for each student ticket. Mrs. Williams purchased 7 tickets (some students and some adult) for $56.95. Which system of equations could be used to find a, the number of adult tickets, and s, the number of student tickets purchased?
Answers
Answer:
Two adult tickets and 5 student tickets
Step-by-step explanation:
Let a=adult tickets Let s=student tickets
You know that each adult ticket is $9.10 and each student ticket cost $7.75. At the end, it cost $56.95 for both students and adults so the first equation should be 9.10a+7.75s=56.95. To get the second equation, you know that Mrs. Williams purchased 7 tickets in total that were both students and adults. Therefore, the second equation should be a+s=7. The two equations are 9.10a+7.75s=56.95
a+s=7.
Now, use substitution to solve this. I will isolate s from this equation so the new equation should be s=-a+7. Plug in this equation to the other equation, it will look like this 9.10a+7.75(-a+7)=56.95. Simplify this to get 9.10a-7.75a+54.25=56.95. Simplify this again and the equation will become 1.35a=2.70. Then divide 1.35 by each side to get a=2. This Mrs. Williams bought two adult tickets. Plug in 2 into a+s=7, it will look like this (2)+s=7. Simplify this and get s=5. This means Mrs. Williams bought five adult tickets. Therefore she bought 2 adult tickets and 5 student tickets.

Follow me! :)
The value of angle x will be 91° for the given triangle.
What is a triangle?A triangle is a polygon with three sides, three vertices (corners), and three angles. The sum of the three angles in a triangle is always 180 degrees. Triangles are important in geometry and mathematics, and they have many applications in science, engineering, and everyday life.
Triangles can also be used to calculate the areas of various two-dimensional shapes and to solve problems related to distance, angles, and proportions.
Triangle fixed value = 180
x = 180 - (45 + 44)
x = 180 - 89
x = 91
Therefore, the value of x is 91°

A hose fills a 10,000-gallon swimming pool at a rate of 10 gallons per minute. what is the domain and range?
Answers
Answer:
Domain: 0 minutes to time it takes to fill. Range: 0 to a 10,000 gallons
Step-by-step explanation:
The domain will be from 0 minutes to time it takes to fill i.e., 1000 and range will be from 0 to 10000 gallons.
It is given that a hose fills 10000 gallon swimming pool at rate of 10 gallons per minute.
We have to find the domain and range.
What do you mean by domain and range ?
The domain is the set of all values for which the function is defined and the range of the function is the set of all values that function takes.
As per the question ;
Capacity of swimming pool = 10000 gallons
Rate of filling = 10 gallons per minute
So ;
Time taken in filling the swimming pool will be ;
= 10000 / 10
= 1000 minutes
So ;
The domain will be from 0 to 1000 minutes i.e., time taken to fill the swimming pool.
Whereas ;
The range will be from 0 to 10000 gallons i.e., amount of swimming pool filled.
Thus , the domain will be from 0 minutes to time it takes to fill i.e., 1000 and range will be from 0 to 10000 gallons.
