Answer:

The answer is "7 + (one-fifth + n) = (7 + one-fifth) + n".

Step-by-step explanation:

In the associative property we add the values, when we add the values it will give the same result, that's why in this choices only the above choice were correct, which can be explained as follows:

What is the length of the mid segment of this trapezoid ; a(-2,4) b(4,3) c(4,-5) d(-2,-2)

Elina [12.6K]

Answer:

$7\ units$

Step-by-step explanation:

we have

a(-2,4), b(4,3), c(4,-5), d(-2,-2)

step 1

Plot the vertices to better understand the problem

using a graphing tool

The graph in the attached figure

step 2

Find the mid-segment parallel to ad and bc

Note : The mid-segment is parallel to the parallel bases of trapezoid

Let

e ---> midpoint segment ab

f ---> midpoint segment cd

The formula to calculate the midpoint between two points is equal to

$(\frac{x1+x2}{2},\frac{y1+y2}{2})$

Find the midpoint e

we have

a(-2,4) and b(4,3)

substitute the given values

$e\ (\frac{-2+4}{2},\frac{4+3}{2})$

$e\ (1,3.5)$

Find the midpoint f

we have

c(4,-5), d(-2,-2)

substitute the given values

$f\ (\frac{4-2}{2},\frac{-5-2}{2})$

$f\ (1,-3.5)$

step 3

Find the length of the mid-segment ef

we have

$e\ (1,3.5)$

$f\ (1,-3.5)$

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

substitute

$d_e_f=\sqrt{(-3.5-3.5)^{2}+(1-1)^{2}}$

$d_e_f=\sqrt{(-7)^{2}+(0)^{2}}$

$d_e_f=\sqrt{49}\ units$

$d_e_f=7\ units$

Helpppppppppppppppp ill mark you brainlist write in y=mx+b form

Sholpan [36]

Answer:

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

$y\:=\:\frac{-10}{7}x-\frac{45}{7}$

Step-by-step explanation:

Given the points

(-8, 5)

(-1, -5)

Finding the slope

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(-8,\:5\right),\:\left(x_2,\:y_2\right)=\left(-1,\:-5\right)$

$m=\frac{-5-5}{-1-\left(-8\right)}$

$m=-\frac{10}{7}$

We know the slope-intercept form of the line equation is

$y = mx+b$

where m is the slope and b is the y-intercept

substituting m = -10/7 and (-8, 5) in the slope-intercept form to determine the y-intercept

$5\:=\:\frac{-10}{7}\left(-8\right)+b$

$\frac{80}{7}+b=5$

$b=-\frac{45}{7}$

now substituting m = -10/7 and b = -45/7 in the slope-intercept form

$y = mx+b$

$y\:=\:\frac{-10}{7}x+\left(-\frac{45}{7}\right)$

$y\:=\:\frac{-10}{7}x-\frac{45}{7}$

Thus, the equation of the line in slope-intercept form is:

$y\:=\:\frac{-10}{7}x-\frac{45}{7}$

The volume of a cone is 1,782 cubic centimeters. a cylinder has the same radius and height as the cone. what is the volume of th

Valentin [98]

The volume of the cylinder that has same height and radius with the given cone is 5,346 cm³

<h3>What are the 3-D figure? </h3>

Pyramids and prisms are examples of three-dimensional shapes, as are shapes with curved surfaces. The three-dimensional prism shape has two bases that are parallel and congruent. Any polygon is acceptable for the bases, which are two of the faces. Rectangles make up the remaining faces.

<h3>What is the Volume of a Cylinder?</h3>

Given that the cylinder and the cone have the same radius and height, the volume of a cylinder equals 3 times the volume of a cone.

According to the given figure:

Given, a cone that has a volume of 1,782 cubic cm, has the same radius and height with a cylinder,

therefore,

Volume of the cylinder = 3 x (1,782)

Volume of the cylinder = 5,346 cubic centimeters

Hence, the volume of the cylinder is 5,346 cubic centimeter.
