Answer:
The answer is the option C
CD≅GH
Step-by-step explanation:
we know that
The Transitive Property of Congruence states that
If [tex]a=b[/tex] and [tex]b=c[/tex]
then
[tex]a=c[/tex]
In this problem we have
CD≅EF and EF≅GH
therefore
CD≅GH -------> by Transitive Property of Congruence
this figure is 1/4 of a circle what is the best approximation for the perimeter of the figure use 3.14 to approximate pi
A) 3.1
B) 6.3
C) 7.1
D) 12. 3
Answer: Option 'C' is correct.
Step-by-step explanation:
Since we know that
The figure is known as "Quadrant" in which angle is 90° .
As we know that "Length of an arc":
[tex]Length=\frac{\theta}{360\textdegree}\times 2\times 3.14\times r\\\\Length=\frac{90\textdegree}{360\textdegree}\times 2\times 3.14\times 2\\\\Length=\frac{1}{4}\times 12.56\\\\Length=3.14[/tex]
Perimeter of the figure is given by
[tex]3.14+2+2=7.1[/tex]
Hence, Option 'C' is correct.

Jerry started doing sit-ups every day. The first day he did 15 sit-ups. Every day after that he did 4 more sit-ups than he had done the previous day. Today Jerry did 65 sit-ups. Write an equation that could be solved to find the number of days Jerry has been doing sit-ups, not counting the first day. Let n represent the number of days.
Thanks
The first day Jerry did 15 sit-ups:
a0 = 15
The 2nd day he did 4 more sit-ups then the previous:
a1 = a0 + 4
The 3rd day he did 4 more sit-ups then the previous:
a2 = a1 + 4
a2 = a0 + 4 + 4
a2 = a0 + 4*4
the (n+1)-th day he did:
an = a0 + 4n
Today Jerry did 65 sit-ups means we have: an = 65 and we need to find n
a0 + 4n = 65
15 + 4n = 65
Now to solve
subtract 15 from both sides
4n = 50
divide both sides by 4
n = 12.5
But I think this is counting the first day
Not counting the first day would be
4n = 65
n = 16.25
I guess that's the answer :)

stewart draws a triangle , and each side is 2 1/6 inches long. Judith draws a square , each side is 1 5/8 inches long . which figure has the greater perimeter, the triangle or the square?
Upon calculating, it is found that both Stewart's triangle and Judith's square have the same perimeter of 6 1/2 inches. This shows that despite different shapes, their perimeters can be equal if the lengths of their sides are chosen accordingly.
Explanation:The question is about comparing the perimeters of a triangle drawn by Stewart and a square drawn by Judith. Stewart's triangle has each side measuring 2 1/6 inches long, which when converted to improper fraction becomes 13/6 inches. For the triangle, the perimeter is calculated by multiplying the length of one side by three (since a triangle has three sides). The perimeter of Stewart's triangle is 13/6 * 3 = 39/6 = 6 1/2 inches.
Judith's square has each side measuring 1 5/8 inches long, which is equivalent to 13/8 inches. For the square, the perimeter is the length of one side times four (because a square has four equal sides). Thus, the perimeter of Judith's square is 13/8 * 4 = 52/8 = 6 1/2 inches.
Therefore, both the triangle and the square have the same perimeter of 6 1/2 inches.

What number could be added to 0.40 mL for the level of precision to be 0.01mL
Answer:
- 0.39
Step-by-step explanation:
Level of precision = 0.01 mL
We need to find a number which could be added to 0.40 mL for the level of precision to be 0.01 mL .
Let x be a number which could be added to 0.40 mL for the level of precision to be 0.01 mL .
[tex]x+0.40=0.01[/tex]
On subtracting 0.40 from both sides , we get
[tex]x+0.40-0.40=0.01-0.40[/tex]
On solving , we get
[tex]x+0=0.01-0.40[/tex]
We know that [tex]x+0=x=0+x[/tex] where 0 is the additive inverse .
So,
[tex]x=0.01-0.40[/tex]
Here , [tex]0.01-0.40=-0.39[/tex]
Therefore ,
[tex]x=0.01-0.40=-0.39[/tex]
Therefore , -0.39 could be added to 0.40 mL for the level of precision to be 0.01mL

consider the following system with a solution (1,3) equation 1 of the system 2x+y=5 equation 2 of the system x-2y=-5 prove that replacing the first equation with the sum of the equation and a multiple of the other produces a system with the same solution
To prove that replacing the first equation with the sum of the equation and a multiple of the other produces a system with the same solution, we will first calculate the solution to the original system. Then we will calculate the solution to the modified system of equations and check if the solution is the same.
Explanation:To prove that replacing the first equation with the sum of the equation and a multiple of the other produces a system with the same solution, we will first calculate the solution to the original system of equations (1,3). Then we will calculate the solution to the modified system of equations in which the first equation is replaced with the sum of the two equations. If the solution to the modified system is also (1,3), then we have shown that the modified system has the same solution.
Original system:
Equation 1: 2x + y = 5
Equation 2: x - 2y = -5
Substitute x = 1 and y = 3 into the original equations to check if it is a solution:
Equation 1: 2(1) + 3 = 5 => 2 + 3 = 5 => 5 = 5 (true)
Equation 2: 1 - 2(3) = -5 => 1 - 6 = -5 => -5 = -5 (true)
Hence, (1,3) is a solution to the original system of equations.
To create the modified system, we will sum equation 1 and a multiple of equation 2:
New equation 1: (2x + y) + k(x - 2y) = 5 + k(-5), where k is a constant
Expanding and simplifying the equation:
(2 + k)x + (1 - 2k)y = 5 - 5k
Let's substitute x = 1 and y = 3 into the modified equation to check if (1,3) is a solution:
(2 + k)(1) + (1 - 2k)(3) = 5 - 5k
2 + k + 3 - 6k = 5 - 5k
3 - 5k = 5 - 5k
3 = 5 (false)
Therefore, the modified system does not have the same solution as the original system, disproving the statement.

Why is subtracting an expression similar to distributing -1? Explain.
Subtracting an expression is akin to distributing -1 to each term within the expression. This is because subtraction can be viewed as adding the negation of the expression, which involves multiplying each term by -1. So, each term within the expression gets negated when subtracting.
When you subtract an expression, you can think of it as distributing a negative sign (-1) to each term within the expression. Here's a step-by-step explanation:
Start with the expression you want to subtract from, let's call it A.
When you subtract another expression, let's call it B, from A, you're essentially adding the negation of B to A.
The negation of B is obtained by multiplying each term of B by -1.
Distributing -1 to each term of B results in subtracting each term of B individually from A.
This process aligns with the distributive property, making subtracting an expression akin to distributing -1 to each term within the expression.

A human society has 73 dogs and cats to be adopted. the number of cats is 10 more than twice the number of dogs. Write a system of linear equations that represent this situation. How many of each animal is up for adoption?
A linear equation of one variable is expressed in the form of ax + b = 0, where a and b are the two integers, and x is a variable.
In the given question, the linear equation can be represented as:
2x + 10 + x = 73.
The number of dogs is 21, and the number of cats available is 52.
Given that:
Total number of dogs and cats = 73
Let the number of dogs be x.
The number of cats, as given is = 10 + 2x
Now, solving for the equation:
x + 10 + 2x = 73
Solving for the variables:
3x + 10 = 73
3x = 73 -10
3x = 63
x = [tex]\dfrac {63}{3}[/tex]
x = 21
The number of dogs available is 21.
The number of cats available is:
2x + 10
Putting the value of x:
2 (21) + 10
52
Thus, the number of dogs is 21, and the number of cats available is 52.
