What is the total surface area of the square pyramid? ​

Answer:

[tex]1.6m^3[/tex] sand is to be added to make sand percentage [tex]60\%[/tex]

Step-by-step explanation:

From the question we are told that:

Total soil [tex]N=3.2m^3[/tex]

Initial sand percentage [tex]S_1=40\%[/tex]

Final sand percentage[tex]s_2=60\%[/tex]

Generally the sand and other particles division is mathematically given by

[tex]40\% of 3,2=1.28[/tex]

and

[tex]60\% of 3.2=1.92[/tex]

Generally  what will make 60\% of 3.2 40\% is mathematically given by

[tex]x=1.92*0.4\\x=4.8[/tex]

Generally the sand to be added is mathematically given by

[tex]4.8sand-3.2sand =1.6m^3[/tex]

Therefore

[tex]1.6m^3[/tex] sand is to be added to make sand percentage [tex]60\%[/tex]

Step-by-step explanation:

Answer:

A. a regular trapezoid

B. they both have at least a pair of parallel sides

Step-by-step explanation:

Trapezoids have only one pair of parallel sides; parallelograms have two pairs of parallel sides. A trapezoid can never be a parallelogram.

Answer:

20

Step-by-step explanation:

x / 100 = 0.2

Multiply both sides by 100 to isolate x. 100 x 0.2 = 20

In the given expression the missing term is 20.

Use the concept of fraction defined as:

A fraction is a part of the whole number and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called a fraction. It can be written in the form of p: q, which is equivalent to p / q.

The given expression is:

?/100 = 0.2

Then we have to find out the missing term.

Let the missing term is x

Therefore, we can write,

x/100 = 0.2

Multiply 100 on both sides we get,

x = 0.2 x 100

x = 20

Hence,

The missing term is 20.

Answer:

x=33

Step-by-step explanation:

1) write the equation: 180=90+(x+15)+(x+9)

2) subtract 90 on both sides and add x+15 and x+9 together: 90=2x+24

3) subtract 24 from both sides: 66=2x

4) divide both sides by 2: x=33

When you see the word "linear," think "line."  Only one of the four given graphs is a straight line:  C

A scale drawing with a 1: 0,8 scale will have sides that measure 2.24, 1.6, and 3.2.

A scale drawing refers to a drawing that has been made bigger or smaller but preserves the proportions of a drawing.

The first step is to decide the scale. In this case, the best scale is 1:0.8, which means the new drawing is 0.2 smaller. This scale is ideal because this sign is slightly bigger than regular signs.

Draw the sign by multiplying each side by the scale (0,8).

Answer:

x = - 6, x = 7

Step-by-step explanation:

Begin by equating to zero

x² - x - 42 = 0

Consider the factors of the constant term (- 42) which sum to give the coefficient of the x- term (- 1)

The factors are - 7 and + 6 , since

- 7 × + 6 = - 42 and - 7 + 6 = - 1 , then

(x - 7)(x + 6) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 6 = 0 ⇒ x = - 6

x - 7 = 0 ⇒ x = 7

Answer:

1 1/30 gallon

Step-by-step explanation:

Can A = 1/3 gallon

Can B = 1/5 gallon

Can C = 1/2 gallon

Total paint Neil has = Can A + Can B + Can C

= 1/3 + 1/5 + 1/2

The lowest common multiple of 3, 5 and 2 is 30

= (10+6+15) / 30

= 31/30

= 1 1/30 gallon of paint

Neil has a total of 1 1/30 gallon of paint

Answer:

37.3032cm^2

Step-by-step explanation:

Given data

Diameter= 0.6cm

Radius= 0.3cm

Lenght = 19.5cm

Surface area (A) =2πrh+2πr^2

Substitute

A=2*3.14*0.3*19.5+2*3.14*0.3^2

A=36.738+0.5652

A=37.3032

Hence the surface area is

37.3032cm^2

Answer:

p(x) = 2*x^4 - 2*x^3 - 52*x^2 - 48*x

Step-by-step explanation:

For a polynomial p(x) with leading coefficient A, and zeros: {x₁, x₂, ...,xₙ}

The polynomial can be written in the factored form as:

P(x) = A*(x - x₁)*(x - x₂)*...*(x - xₙ)

In this case, we know:

Leading coefficient equal to 2, and the zeros are: 0, -1, 6, and -4

Then the polynomial can be written as:

p(x) = 2*(x - 0)*(x - (-1))*(x - 6)*(x - (-4))

p(x) = 2*x*(x + 1)*(x - 6)*(x + 4)

The wanted polynomial is this one, and we can expand it to get:

p(x) = (2*x^2 + 2*x)*(x - 6)*(x + 4)

p(x) = (2*x^3 - 12*x^2 + 2*x^2 - 12*x)*(x + 4)

p(x) = (2*x^3 - 10*x^2 - 12*x)*(x + 4)

p(x) = 2*x^4 + 8*x^3 - 10*x^3 - 40*x^2 - 12*x^2 - 48*x

p(x) = 2*x^4 - 2*x^3 - 52*x^2 - 48*x

Answer:

a = 4, x = 1

Step-by-step explanation:

The opposite sides of a parallelogram are congruent , then

WX = YZ , that is

a² + 5a = 5a + 16 ( subtract 5a from both sides )

a² = 16 ( take the square root of both sides )

a = ± [tex]\sqrt{16}[/tex] = ± 4

Since a > 0 , then a = 4

Also

XY = WZ , that is

x² + 6x = 4x + 3 ( subtract 4x + 3 from both sides )

x² + 2x - 3 = 0 ← in standard form

(x + 3)(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x - 1 = 0 ⇒ x = 1

Since x > 0 , then x = 1

Answer:

-8

Step-by-step explanation:

88=(-x+3)8

88= -8x+24

88-24= -8x

64= - 8x

- x= 64/8

-x=8

x= -8

88 = ( -x + 3) x 8

88 = (3-x) x 8

8= 8 (3-x)

88/8 = 3 - x

11 - 3 = -x

8 = -x

-8 = x

x = -8
