Answer:
12
Step-by-step explanation:
Perimeter of ΔABC = 12+ perimeter of ΔACD
Perimeter of ΔABC= AC+CB+BA
Perimeter of ΔACD=AC+CD+DA
But, CB=CD +DB
DA ≅DB since there is a ⊥bisector trough D and
Therefore,
Perimeter of ΔABC= (AC+CD+DA)+BA = Perimeter of ΔACD +12 therefore AB=12

the ratio of males to females at camp is 5 to 4. if there are 40 males at the camp, how many females are there?
Answers
Answer:
32
Step-by-step explanation:
5:4 is the ratio. So 40/5 is 8. Therefore, you must multiply 4 by 8 to get the amount of females at the camp. Ergo, the answer is 32
Answer:
32
Step-by-step explanation:
You can solve this by setting up a proportion.
A 5 to 4 ratio is the same as [tex]\frac{5}{4}[/tex]
The proportion is [tex]\frac{5}{4}[/tex] = [tex]\frac{40}{x}[/tex]
By cross multiplying... you find that x (females) is equal to 32

What is the greatest common factor, and how is the distributive property used to factor it out from a polynomial?
Answers
Answer:
To factor a polynomial, identify the greatest common factor of the monomial terms, and then use the Distributive Property to rewrite the expression. Once a polynomial in a • b + a • c form has been rewritten as a(b + c), where a is the GCF, we say that the polynomial is in factored form.

What is the solution of the system of equations shown above?
Answers
Answer:
x = -3
Step-by-step explanation:
First solve it:
Subtract the x's from both sides
2y = -3x +8
2y = -5x +2
Divide by two
y= -1.5x + 4
y = -2.5x +1
set them equal to each other:
-1.5x +4 = -2.5x +1
Add 2.5 x to both sides
1x +4 = 1
x +4 = 1
subtract 4 from both sides
x = -3

(2,8),(7,8) slope of the line
Answers
Answer:
The slope of line is 0 given points (2,8)(7,8)
Step-by-step explanation:
We need to find slope of line given points (2,8),(7,8)
The formula used to find slope of line is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We are given:
[tex]x_1=2, y_1=8, x_2=7 \ and \ y_2=8[/tex]
Finding slope using formula:
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{8-8}{7-2}\\Slope=\frac{0}{5}\\Slope=0[/tex]
So, the slope of line is 0

The Directions are, “Find the Percent Change. Specify an increase or a decrease.”
13. original amount: 25
amount of increase: 4
This is worth 12 pts!
Answers
Answer:
Percent Change is 16%
The change is increased.
Step-by-step explanation:
The original amount = 25
Amount increase = 4
We need to find percent increase
The formula used is: [tex]\frac{Amount \ increased}{Original \ Amount}*100[/tex]
Putting values in formula
[tex]Percent \ Change = \frac{Amount \ increased}{Original \ Amount}*100\\Percent \ Change =\frac{4}{25}*100\\Percent \ Change =16 \%[/tex]
So, Percent Change is 16%
The change is increased.

Find a positive number for which the sum of it and its reciprocal is the smallest (least) possible. Let x be the number and let S be the sum of the number and its reciprocal. Write the objective function in terms of x. S(x) nothing The interval of interest of the objective function is nothing. (Simplify your answer. Type your answer in interval notation.) The number is 0.
Answers
Answer:
[tex]S(x) = x + \frac{1}{x}[/tex] --- Objective function
Interval = [tex]\{x:x=1\}[/tex]
Step-by-step explanation:
Given
Represent the number with x
The required sum can be represented as:
[tex]x + \frac{1}{x}[/tex]
Hence, the objective function is:
[tex]S(x) = x + \frac{1}{x}[/tex]
To get the the interval, we start by differentiating w.r.t x
Using first principle, this gives:
[tex]S'(x) = 1 - \frac{1}{x^2}[/tex]
Equate S'(x) to 0 in order to solve for x
[tex]0 = 1 - \frac{1}{x^2}[/tex]
Subtract 1 from both sides
[tex]0 -1 = 1 -1 - \frac{1}{x^2}[/tex]
[tex]-1 = - \frac{1}{x^2}[/tex]
Multiply both sides by -1
[tex]1 = \frac{1}{x^2}[/tex]
Cross Multiply
[tex]x^2 * 1 = 1[/tex]
[tex]x^2 = 1[/tex]
Take positive square root of both sides because x is positive
[tex]\sqrt{x^2} = \sqrt{1[/tex]
[tex]x = 1[/tex]
Representing x using interval notation, we have
Interval = [tex]\{x:x=1\}[/tex]
To get the smallest sum, we substitute 1 for x in [tex]S(x) = x + \frac{1}{x}[/tex]
[tex]S(1) = 1 + \frac{1}{1}[/tex]
[tex]S(1) = 1 + 1[/tex]
[tex]S(1) = 2[/tex]
Hence, the smallest sum is 2
