Hello, you can use the formula which is [tex]v=lwh/3[/tex]

Answer:

Step-by-step explanation:

The can contains 1 pound + 2 oz

1 pound = 16 oz

1 can = 16oz + 2oz

1 can = 18 oz

2/3 can = 18 oz * 2/3

2/3 can = 18 oz/1 * 2/3

Multiply the numerator * numerator divide by (denominator * denominator)

2/3 can = 36 / 3

2/3 can = 12 oz.

You could do this by cancelation, but you may not know that yet.

All equations equivalent to 8+3x = -2(11) are:

2(8+3x) = -4(11) and -8 - 3x = 2(11)

Answer:

X=7/2 Y=1

Step-by-step explanation:

4X-Y=13

4X-13=Y

2X-3(4X-13)=4

2X-12X+39=4

-10X+39=4

-10X=4-39

-10X=-35

X=7/2(-35/10)

Y=4(7/2)-13

Y=14-13

Y=1

The solution of the two given linear equations will be equal to X=7/2 Y=1

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

The solution of the linear equation is as follows:-

4X  -  Y   =    13

4X  -  13   =   Y

2X   -   3  (   4X  -  13  )   =    4

2X   -   12X   +    39   =    4

-10X   +    39  =  4

-10X  =    4  -   39

-10X    =    -35

X   =    7/2   (  -35  /   10   )

Y   =   4  (  7/2  )  -   13

Y   =  14  -  13

Y  =   1

Therefore the solution of the two given linear equations will be equal to X=7/2 Y=1

The amount of paint required by Madeline will be 0.8325 gallons

Given that

[tex]1cm=1.5ft[/tex]

We will first find the area of the wall

Area of the wall = Area of trapezoidal shape+ Area of triangular shape

Area of trapezoid = [tex]\dfrac{a+b}{2} \times h[/tex]

a= 4cm

b=14cm

h=10cm

putting this values

[tex]A=\dfrac{4+14}{2} \times 10[/tex]

[tex]A=90cm^{2}[/tex]

Area of triangular shape=  [tex]\dfrac{1}{2} \times width\times height[/tex]

width=14cm

height=8cm

putting the values

[tex]A=\dfrac{1}{2} \times 14\times 8=58cm^{2}[/tex]

[tex]Total area of the wall= 90+58=148cm^{2}[/tex]

since we have

[tex]1cm=1.5ft[/tex]

[tex]148cm^{2} = 148\times (1.5)^{2} =333 ft^{2}[/tex]

Now

[tex]1gallon = 400ft^{2}[/tex]

so for  [tex]333 ft^{2}[/tex]  amount of paint in gallons required will be

[tex]1ft^{2} =\dfrac{1}{400} gallons[/tex]

[tex]333ft^{2} =\dfrac{333}{400} gallons=0.8325gallons[/tex]

Thus the amount of paint required by Madeline will be 0.8325 gallons

The perimeter of the triangle CFX is the sum of lengths CF, FX and XC

The perimeter of the triangle CFX is 82 units

The given parameters are:

CE=5, YF=21 and XZ=15

Points E, Y and Z are the median of the triangle CFX.

This means that:

CF = 2 * CE

FX = 2 * YF

XC = 2 * XZ

The perimeter of triangle CFX is then calculated as:

Perimeter = CF + FX + XC

This gives

Perimeter = 2 * CE + 2 * YF + 2 * XZ

So, we have:

Perimeter = 2 * 5 + 2 * 21 + 2 * 15

Perimeter = 82

Hence, the perimeter of the triangle CFX is 82 units

  the first three are polynomials; the remainder are not

Step-by-step explanation:

A polynomial is a sum of terms with non-negative integer powers of the variables.

The first three expressions are all polynomials; the last three are not.

The rational expression with a variable in the denominator is a "rational function", but is not a polynomial. The expressions containing |x| and √x are not expressions that have x to an integral power.

The coefficients of the polynomials we generally deal with are usually integers or fractions. However, there is no requirement that they be rational or real. The second expression is still a polynomial even though it has irrational coefficients.

Step-by-step explanation:

x² - 12x + 36 = 49

(x - 6)² = 49

now taking the square root

x - 6 = 7

x = 13

the second solution is (remember, sqrt(a²) = ±a)

-(x - 6) = 7

-x + 6 = 7

-x = 1

x = -1

Answer:

C D F

Step-by-step explanation:

Taking -40/2, we know our answer must be -20.

Testing each answer choice proves this.

A= 40*1/2, which is equal to 40/2, which is 20.

B= -40*-1/2, again, equaling 20.

C= 40/-2. Since one of our terms is negative, this one is -20.

D= 40*-1/2, again, -20.

E= -1/40*2. This would equal -2/40, using fraction multiplication.

F= -40*1/2, Which is the exact same thing the original question asks.

Thus, our final answer is C, D, and F.

Step-by-step explanation:

I am not sure what you mean by "sort". that would mean to bring them into a certain sequence.

I think you mean "categorize".

the first one is arithmetic.

the added constant is -4.2

98.3 - 4.2 = 94.1

94.1 - 4.2 = 89.9

...

the second one is neither.

it looks like first to be arithmetic with the added constant of -1.

1 - 1 = 0

0 - 1 = -1

but then

-1 - 1 = -2 and not 0.

the third is geometric.

the ratio or multiplication factor is 2.

1.75 × 2 = 3.5

3.5 × 2 = 7

...

the fourth is arithmetic.

the added constant is 1.2.

-12 + 1.2 = -10.8

-10.8 + 1.2 = -9.6

...

the fifth is geometric.

the ratio of multiplication factor is -1.

-1 × -1 = 1

1 × -1 = -1

...

if you really need to sort them (change their positions in that 5 elements list), then

the 1st and 4th are arithmetic (to be put into the top 2 spots).

the 3rd and 5th are geometric (to be put into the next 2 spots).

the 2nd is neither (last spot).
