Answer: -280000

Step-by-step explanation: Remove parentheses: (a)=a   =12x10 4  - 4x10 5

12x10 4 = 120000

4x10 5=400000

=120000-400000

then subtract the numbers:120000-400000= -280000

The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

Step-by-step explanation:

Convert these mixed fractions to improper fractions.

3 3/5 = 18/5

-8 1/3 = -25/3

Now, it is easier to multiply them. Multiply the numerators and the denominators.

18  x   25   =   450

5          3           15

Simplify the final answer by dividing 450 ÷ 15, which is 30.

Step-by-step explanation:

(6,6) is the only possible outcome of getting a total of 12

Step-by-step explanation:

Let x be the smallest even integer.

Then (x + 2) and (x + 4) are the other even integers.

We have x + (x + 2) + (x + 4) = 138.

=> 3x + 6 = 138

=> 3x = 132

=> x = 44.

Hence the smallest integer is 44.

1/3

The equivalent value of the fraction is A = 1/3

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first fraction be p

Let the second fraction be q

Now , A = p - q

when the value of p = 17/15

And , when the value of q = 4/5

On simplifying the equation , we get

A = 17/15 - 4/5

So , the left hand side of the equation is equated to the right hand side by the value of ( 17/15 - 4/5 )

A = ( 17/15 - 4/5 )

Taking the LCM of the denominators of the fraction , we get

A = ( 17 - 12 ) / 15

On simplifying , we get

A = 5/15

A = 1/3

Therefore , the value of A = 1/3

Hence , the fraction is A = 1/3

Answer: Yes

Step-by-step explanation: bc 6(-3)+5=5(-3)+8+2(-3)

Becomes -18+5=-15+8+-6 which equals -13 on both sides meaning -3 is a solution

6x+5=5x+8+2x

Answer:

y = 1/2x + 1

Step-by-step explanation:

In order to evaluate a slope that is perpendicular to the given equation, you need to find the opposite reciprocal of the original slope. This means you take the original slope, flip the numerator and the denominator, and change the sign in front.

-2 ⇒ 1/2

Next, we need to substitute the information given into the point-slope formula.

The point-slope formula is:

y - y₁ = m(x - x₁)

y - 1 = 1/2(x - 0)

y - 1 = 1/2x

y = 1/2x + 1

Therefore, the line perpendicular to y = -2x + 2 is y = 1/2x + 1.

Answer:

  168 cubic inches

Step-by-step explanation:

The formula for the volume of a pyramid is ...

  V = (1/3)Bh

where B is the area of the base, and h is the height.

The base is a rectangle, whose are is given by the formula ...

  A = LW

  A = (8 in)(7 in) = 56 in²

Then the pyramid volume is ...

  V = (1/3)(56 in²)(9 in) = 168 in³

The volume of the pyramid is 168 cubic inches.

Step-by-step explanation:

Answer:

radius r = 3.414 in

height h = 6.8275 in

Step-by-step explanation:

From the information given:

The volume V of a closed cylindrical container with its surface area can be expressed as follows:

[tex]V = \pi r^2 h[/tex]

[tex]S = 2 \pi rh + 2 \pi r^2[/tex]

Given that Volume V = 250 in²

Then;

[tex]\pi r^2h = 250 \\ \\ h = \dfrac{250}{\pi r^2}[/tex]

We also know that the cylinder contains top and bottom circle and the area is equal to πr²,

Hence, if we incorporate these areas in the total area of the cylinder.

Then;

[tex]S = 2\pi r h + 2 \pi r ^2[/tex]

[tex]S = 2\pi r (\dfrac{250}{\pi r^2}) + 2 \pi r ^2[/tex]

[tex]S = \dfrac{500}{r} + 2 \pi r ^2[/tex]

To find the minimum by determining the radius at which the surface by using the first-order derivative.

[tex]S' = 0[/tex]

[tex]- \dfrac{500}{r^2} + 4 \pi r = 0[/tex]

[tex]r^3 = \dfrac{500 }{4 \pi}[/tex]

[tex]r^3 = 39.789[/tex]

[tex]r =\sqrt[3]{39.789}[/tex]

r = 3.414 in

Using the second-order derivative of S to determine the area is maximum or minimum at the radius, we have:

[tex]S'' = - \dfrac{500(-2)}{r^3}+ 4 \pi[/tex]

[tex]S'' = \dfrac{1000}{r^3}+ 4 \pi[/tex]

Thus, the minimum surface area will be used because the second-derivative shows that the area function is higher than zero.

Thus, from [tex]h = \dfrac{250}{\pi r^2}[/tex]

[tex]h = \dfrac{250}{\pi (3.414) ^2}[/tex]

h = 6.8275 in
