Answer:

2.32 gallons of paint

Step-by-step explanation:

First, find the area of all 4 sides of the room, with the equation A = lw

11(10)

= 110 (for 2 of the walls)

18(10)

= 180 (for the other 2 walls)

Add these up:

110 + 110 + 180 + 180

= 580

Then, divide this by 250:

580/250

= 2.32

So, 2.32 gallons of paint will be needed to paint the room.

Multiply and simplify. 2x4yx⋅6xy2z3
OLEGan [10]

Answer:

The given expression 2x^4yx \times 6xy^2z^3   on multiplying  is 12x^6y^3z^3

Step-by-step explanation:

Consider the given two expressions 2x^4yx and 6xy^2z^3

We have multiply both expressions,

2x^4yx \times 6xy^2z^3

To multiply two terms first multiply constant numbers that is 6 × 2 = 12

For x , y and z apply property of exponent,

x^a\cdot x^b=x^{a+b}

Then power of x together will be,

x^4\cdot x\cdot x=x^{4+1+1}=x^6

Similarly for y powers,

y \cdot y^2=y^{1+2}=y^3

Since first term do not have any expression for z so it will remain same.

Thus, the given expression  on multiplying become,

2x^4yx \times 6xy^2z^3 is 12x^6y^3z^3

A distance is related to time according to the expression x = A sin(2πft), where A and f are constants. Find the dimensions of A
nika2105 [10]

Answer:

[M⁰L¹T⁰]

Step-by-step explanation:

given expression,

from the expression  x = A sin (2 π f t),

A and f are constants

dimension of A =?  

As the sine factor is dimensionless means that sine function will not have any dimension it is dimensionless.

so, remaining  

x = A sin ()

so, the dimension of x is L  

hence, the dimension of A also will be equal to L i.e [M⁰L¹T⁰]
