A company is creating a box without a top from a piece of cardboard, but cutting out square corners with side length x.
Volgvan
Answer: Choice B) The expression (10-2x)(30-2x)x represents the volume of the box

----------------------------------------------------
----------------------------------------------------

The original width is 10 inches. The width reduces to 10-2x inches after we cut off the top two corners of the rectangle. We can think of it as taking 10 and subtracting off two copies of x like so: 10-x-x = 10-2x

Similarly, the length goes from 30 inches to 30-2x inches. This time we're taking off the top and bottom corners (focus on either side it doesn't matter). 

The height of the box is x inches due to this portion being folded up. 

Volume of box = (width)*(length)*(height)
Volume of box = (10-2x)(30-2x)x

Note: the units for the answer are in cubic inches which can be written as "in^3" (inches cubed).

You can use the formula S = 10m2/3 to approximate the surface area, S, in square centimeters, of a horse with mass m, in grams.
Vaselesa [24]

S = 10*m^(2/3)

S = 10*(450000)^(2/3)

S = 58,723.014617533

S = 58,723

<h3>Answer: Approximately 58,723 square cm.</h3>

Simplify (-7/8)(-3/4).
murzikaleks [220]

Answer:

<h2>21/32</h2>

Step-by-step explanation:

-7/8 × -3/4 = 21/32

-7 × -3   = 21  

-8 × -4   = 32

21/32

<u><em>IMPORTANT: This number is not negative, because a negative times a negative is a positive.</em></u>

By the way, if you didn't know how to arrive at the fraction here's how.

First, Address input parameters & values.

Input parameters & values: The decimal number = 0.65625. Then, write it as a fraction

0.65625/1

Multiply by 100000 both the numerator & denominator

(0.65625 x 100000)/(1 x 100000) = 65625/100000

65.625% = 65.625/100 or 65625/100000

Find LCM (Least Common Multiple) for 65625 & 100000.

3125 is the LCM for 65625 & 100000

Divide by 3125

65625/100000 = (65625 / 3125) / (100000 / 3125)

= 21/32

I'm always happy to help :)

Using a pencil, paper, and protractor, or a drawing program, draw an isosceles triangle that has exactly one 50° angle. Use the
Ira Lisetskai [31]

Sorry my lighting is really bad.

Note: my drawing is NOT to scale (because I don't have a protractor)

Ok so an isosceles triangle has 2 congruent sides and 1 other side. That means that the (one) 50° angle is the vertice (edge) of the 2 congruent sides. The vertice of the other sides are 65° because the angles of a triangle add up to 180°.

180°-50°=130°

The other angles are the same so 130° ÷ 2 = 65°

Since the two longer sides are congruent, mark them with one line each.

The other side is different so mark that with two lines.

If another person were given these same instructions, their drawing would look the same.

If you had a protractor, there would be a slight difference but it would still look the same (because a protractor is a tool that is very exact and it is quite accurate).

Also, if you didn't have a protractor, it wouldn't be the same.]

But even if someone else's drawing look different than yours (and mine), but the point would be the same because they know the congruent sides by the markings and they know the angles.

So if another person saw these same instructions and drew the triangle, it would look the same, but it wouldn't be exactly similar.

♡ Hope this helps! ♡

1 is a, since the MN would match up with PQ and PR would match up with MO
2  7x - 5 = 5x + 11
2x - 5 = 11
2x = 16
x = 8

Plug x back in
7(8) - 5 = 56 - 5 = 51 so B
