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?

Answers

Final answer:

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 you can do for this case is graph the data in a computer program, for example, excel and look for the trend line of the function.
 For this case, the function has a logarithmic behavior, therefore, we choose a linear logarithmic trend.
 The function that best suits the problem is:
 y = 1.4004ln (x) + 0.2158
 The value of R ^ 2 indicates the accuracy of the function
 R² = 0.9691
 For R ^ 2 = 1 the function is completely accurate.
 We note that in that case R² = 0.9691, the function chosen has a good approximation.

Answers

Given two angles of a triangle, we can find the third one by subtracting what we have from 180:
180-63.2-75.9=40.9°.  This means C is correct.
This also means that B is correct; if a triangle is equilateral, all angles must be congruent as well, which these are not.

Cross multiplying the proportion we have:
x*1 = 3(y-3)
1x = 3y - 9
Solving for y, we first cancel the 9 by adding:
1x+9 = 3y
Now we cancel the 3 by dividing:
1x/3 + 9/3 = 3y/3
1/3x + 3 = y
In this format, we can see that the slope (m) is 1/3 and the y-intercept (b) is 3.

Going by the directions for the points P, Q, R, and S, PQ would be parallel to SR and PS would be parallel to QR.  These sides are not parallel to any other sides of this figure.

For the last problem, the vertices given do not form a parallelogram.  There is only 1 pair of parallel sides using these points.

The correct option is (A) (-3,5). The answer covers the relationship between angles in quadrilaterals, properties of triangles, and concepts related to similar triangles and equations.

Angles in quadrilaterals:

In the first scenario, if one angle is 24 degrees more than the other on a straight line, the correct choices are A. The measure of the smaller angle is 33 degrees and D. The measure of the larger angle is 102 degrees.

Triangles:

For the triangle with sides 4.23 meters, the correct statements are A. The triangle is an obtuse triangle and D. The triangle should be isosceles.

Why is subtracting an expression similar to distributing -1? Explain.

Answers

Take the expression 2x - (x - 3).  We know we can multiply everything by 1 and not change it; we know that if a variable does not have a coefficient with it, we can write a 1 beside it.  That means we can write our expression as
2x - 1(x - 3).  This helps us see the distributive property applies here:
2x - 1x - 1(-3)
2x - 1x - -3
2x - 1x + 3
1x + 3 = x + 3

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.

HELP What is the area of this figure?

Answers

The correct answer is:  [B]:  "40 yd² " .
_____________________________________________________
First, find the area of the triangle:

The formula of the area of a triangle, "A":

A = (1/2) * b * h ; 

in which:  " A = area (in units 'squared') ;  in our case, " yd² " ; 

                 " b = base length" = 6 yd.  

                 " h = perpendicular height" = "(4 yd + 4 yd)" = 8 yd.
___________________________________________________
→  A = (1/2) * b * h = (1/2) * (6 yd) * (8 yd) = (1/2) * (6) * (8) * (yd²) ; 
                                                                 
                                                                   =  " 24 yd² " .
___________________________________________________
Now, find the area, "A", of the square:

The formula for the area, "A" of a square:

   A = s² ;

in which:  "A = area (in "units squared") ; in our case, " yd² " ;
                 
                 "s = side length (since a 'square' has all FOUR (4) equal side lengths);

 A = s²  = (4 yd)² = 4² * yd² =  "16 yd² "
_________________________________________________
Now, we add the areas of BOTH the triangle AND the square:
_________________________________________________
        →  " 24 yd²  +  16 yd² " ; 

to get:  " 40 yd² " ;  which is:  Answer choice:  [B]:  " 40 yd² " .

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

Answers

Final answer:

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.

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

Answers

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

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.
