Answer:

$63314.48m^3$

Step-by-step explanation:

$V=whl=28*47*21=27636m^3\\27636*2=55272m^3$ (rectangular prism)

$V=\pi r^2h=\pi *16^2*10\\=8042.48m^3$ (cylinder)

$55272+8042.48\\=63314.48m^3$ (Whole shape)

Answer:

63,318.48 (cube units of some sort?)

Step-by-step explanation:

First, I would split the shape into shapes with formula's to solve them. Let's start with the rectangular boxes on the ends of this dumbbell thing :

Formula for a rectangular prism : V = LWH

V = 21 x 28 x 47 = V = 27,636 (We're gonna multiply this volume by 2 since it states the prisms are identical.) 27,636 x 2 = 55,272

Formula for the volume of a cylinder : V = πr^2h (I assume we are substituting 3.14 for π?)

V = 3.14 x 16^2 x 10 = 8,038.4

All that's left is to add them all together! 55,272 + 8,038.4 = 63,318.48

Simplify the polynomial. Then find its value for the given value of the variable.

zloy xaker [14]

Answer:

simplified: xy²
value: 4

Step-by-step explanation:

The polynomial is simplified by combining like terms. Like terms are identified more easily if the variables in each term are written in the same order. We usually like to use alphabetical order. Two of the like terms have opposite coefficients, so they cancel. The result is ...

(3 1/2 -2 1/2)xy² +(-2 4/5 +2 4/5)x²y

= xy² . . . . simplified expression

For x = 1, y = -2, the value of the expression is ...

(1)(-2)² = 4

Is 1000/1=100 standard form? If not what is it’s standard form

blondinia [14]

Answer:

1000

Step-by-step explanation:

1000/1 = 1000

Multiplying or dividing any number by 1 does not change its value.

In the US, "standard form" is the number written in the usual way: digits to the left and/or right of a decimal point, with zeros as placeholders where required. (If there is no fractional part, the decimal point is optional.*)

In the UK, "standard form" is what is called "scientific notation" in the US. There is one digit to the left of the decimal point, and the remaining significant digits are to the right of the decimal point. The number is multiplied by ten to the power corresponding to the place value of the most significant digit. In this "standard form", 1000 = 1.×10³.

_____

* When you're concerned about significant digits, the presence of a decimal point will indicate any zeros immediately to its left are significant. That is, 20 has 1 significant digit; 20. has 2 significant digits. The zero is indicated as being significant by the presence of the decimal point.
