Let's see. What is a right isosceles triangle?

A right isosceles triangle is a triangle with one right angle with at least two equal sides. In this case, it would have to be ONLY two because it has a right triangle.

What is the formula for the area of an isosceles triangle?

When y = the identical side lengths of the triangle,

and A = area,

(y × y) ÷ 2 = A

Note: Remember to compute from left to right! :)

We divide by two because when you multiple the two identical sides, you would get a square. However, we're trying to find the right isosceles triangle, and we divide by two.

Now, we can plug-in our values!

(y × y) ÷ 2 = 128

(y × y) = 64

Now, we square root both sides!

y = √64

y = 8

The length of the identical sides of the triangle is 8 meters.

Given that area of an isosceles triangle is 128m² .

And the triangle is right Angled ∆ .

So , the measure of sides along 90° that is perpendicular and the base will be equal .

Let us say that each of the equal sides is x .

Then , we can find the area of the triangle as ,

[tex]\boxed{\bf{\red{ Area_{triangle}=\dfrac{1}{2}\times(base)\times(height)}}}[/tex]

Now , here substitute the respective values ,

[tex]\implies \sf \dfrac{1}{2}\times(base)\times(height)=128m^2[/tex]

[tex]\sf\implies \dfrac{1}{2}\times x \times x = 128m^2[/tex]

[tex]\sf \implies \dfrac{x^2}{2}=128m^2[/tex]

[tex]\sf\implies x^2=128\times2 m^2[/tex]

[tex]\sf\implies x^2=256 m^2[/tex]

[tex]\sf\implies x=\sqrt{256m^2}[/tex]

[tex]\underline{\boxed{\red{\sf\longmapsto x=16m}}}[/tex]

Hence the value of value of identical side of the triangle is 16m .

Answer:

what is the answer below

Step-by-step explanation:

Answer:

The answer is x > -1

Step-by-step explanation:

This is because if it were a closed circle, it would have to the include the inequality -1 but since it is an opened circle, that inequality is not included. So in conclusion, Any number could be used to represent x as long as it is a greater number than -1. I hope this makes sense.

x>-1  and  x<-2 are two inequalities that would have the solution set as graphed.

a relationship between two expressions or values that are not equal to each other is called 'inequality.

Answer:

[tex]y=\frac{5}{6} x-2[/tex]

Step-by-step explanation:

Point-slope form:

where [tex](x_1, \ y_1)[/tex] are coordinates of a point that the line passes through, and [tex]m[/tex] is the slope of the line.

We are given two points that the line passes through, but we are not given the slope.

We can find the slope by using the slope formula:

where [tex](x_1, \ x_2)[/tex] and [tex](y_1, \ y_2)[/tex] are two points that the line passes through.

Substitute (-6, -7) and (6, 3) into the slope formula:

The slope of this line is 5/6. Now we are able to use the point-slope equation to find the slope-intercept equation [tex](y=mx+b)[/tex] of this line.

Substitute a point that the line passes through and the slope of the line into the point-slope equation. I'm using the point (6, 3).

Distribute 5/6 inside the parentheses.

Add 3 to both sides of the equation.

This is the equation of the line that passes through (-6, -7) and (6, 3) in slope-intercept form.

Answer:

3

Step-by-step explanation:

10x-6=24

10x = 24+6 (You switch sides because you can add 24 and 6. You cannot add 10x to 24 or 6)

10x= 30

x= 30/10

x= 3

The answer is 3.

Answer:

x=3

Step-by-step explanation:

10x-6=24

Subtract 6 from 6 and then add 6 to 24

10x=30

30÷10=3

Divide 30 by 10

x=3

2.) use the slope formula y2-y1/x2-x1

3.) substitute the points into the equation -4-0/4-2

4.) solve the equation (-4-0= -4) / (4-2= 2)

5.) the slope is -4/2 or -2

Answer:

t=(a+by)/(y-1)

Step-by-step explanation:

(t-b)y =t+a

ty-by=a+by

t(y-1)=a+by

thus,

t=(a+by)/(y-1)

Answer:

[tex]\displaystyle y=-\frac{1}{2}x+1[/tex]

Step-by-step explanation:

The equation of any line in slope-intercept form is:

y=mx+b

Being m the slope and b the y-intercept.

Assume we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Two points are given: (-6,4) and (-2,2). Calculating the slope:

[tex]\displaystyle m=\frac{2-4}{-2+6}=\frac{-2}{4}=-\frac{1}{2}[/tex]

The equation of the line is, so far:

[tex]\displaystyle y=-\frac{1}{2}x+b[/tex]

To calculate the value of b, we use any of the given points, for example (-6,4):

[tex]\displaystyle 4=-\frac{1}{2}(-6)+b[/tex]

[tex]\displaystyle 4=3+b[/tex]

Solving:

b = 1

The equation of the line is:

[tex]\boxed{\displaystyle y=-\frac{1}{2}x+1}[/tex]

We can see none of the choices is correct.

Answer:

25/42

Step-by-step explanation:

first find same denominators

18/42 + 7/42

then add the new fractions

18/42 + 7/42 = 25/42

Hope this helps :)

Have a nice day :)

Can you give me brainliest plz :)

Answer:

25/42

Step-by-step explanation:

You can get to 25/42 by finding the least common denominator, or in layman's terms, by seeing what the lowest number the two denominators can both EQUALLY go in to. in this case it's 42, as both 6 and 7 can go into 42 equally, and 42 is the lowest number that they both can go into. So after you find the least common denominator, you make that the denominator of both fractions, and multiply the two numerators by however many times you had to multiply the denominators by. for example, to get 7 to 42, you need to multiply it by 6, so you would then multiply the numerator, in this case it's 3, 6 times, netting you 18. you do the same thing with the other fraction, since the numerators 1, you multiply it by 7, since you had to multiply 6 by 7 to get 42. this leaves you with 18/42 + 7/42, which you can now normally add together to get 25/42, and since it can't be reduced, it stays this way. Hope this helps :)

Answer:

A

Step-by-step explanation:

21 yards and Total cost of $146.58

p = 1 yard

Equation: 21p = 146.58

p = 146.58/21

p = 6.98

21p=146.58 will describe the equation and the amount paid for each yard is $6.98 so option (A) will be correct.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Amount of fabric = 21 yards

Since cost per yard of fabric is given by p

So,

The total cost of fabric = Amount of fabric ×  cost per yard

146.58 = 21p

21p=146.58

Now,

p = 146.58/21 = 6.98.

Hence "21p=146.58 will describe the equation and the amount paid for each yard is $6.98".
