Answer: A rectangle

Note: I am a bit confused between A), B), and C), but the answer I am going for is C).

Step-by-step explanation:

By definition, a cross-section is the intersection of a plane and a body of three dimensions.

A pentagonal prism has a pentagon as its base. and its lateral faces are rectangles.

If a plane perpendicular cuts the pentagonal prism to the base, this means that the plane is parallel to lateral faces, then, the shape of the cross-section that is formed is also a rectangle.

Adam has been asked to post a parcel for a family member. He has been told that the parcel weighs 12 lbs 8 oz. 1lb = 16 oz 1lb =

yarga [219]

Answer:

Weight of parcel to the nearest whole kilogram = 6 kg

Explanation:

Weight of parcel = 12 lbs 8 oz

1lb = 16 oz also we have 1lb = 454 g

Weight of parcel = 12 lbs 8 oz = 12 + (8/16) lbs = 12.5 lbs

Weight of parcel in g = 12.5*454 = 5675 g

Weight of parcel = 5675 g = 5.675 kg

Weight of parcel to the nearest whole kilogram = 6 kg

Find an equation for the line below. Thanks !

daser333 [38]

Answer:

$\huge\boxed{y=\frac{1}{4}x + \frac{13}{4}}$

Step-by-step explanation:

In order to find the equation to this line, we need to note that we see two points on this graph. Using these two points, we can use them to find the slope of the graph and use one to find the y-intercept.

We know that the slope of a line is defined by $\frac{\Delta y}{\Delta x}$ (change in y / change in x). Therefore, we can use our two points that we know - (-5, 2) and (3, 4) to find the slope.

The change in y is $4 - 2 = 2$ , and the change in x is $3 - (-5) = 3+5= 8$ . Therefore, our slope is $\frac{2}{8} = \frac{1}{4}$ .

Now that we know our slope, our equation in slope-intercept form looks something like this.

$y = \frac{1}{4}x + b$

However, we still have b to solve for. We can solve for this by substituting a point we already know into the equation. Let's substitute (3, 4) inside.

$4 = \frac{1}{4} \cdot 3+b$
$4 = \frac{3}{4} + b$
$b = \frac{16}{4}- \frac{3}{4}$
$b = \frac{13}{4}$

So now we know that the y-intercept is $\frac{13}{4}$ . Plugging that into our equation finishes it off, leaving our final equation to be $y = \frac{1}{4}x + \frac{13}{4}$ .

Hope this helped!
