Which pair of angles are corresponding angles?

Answer: the volume of cube is 64 x6 + 144x4 + 108x2 + 27.

Step-by-step explanation: As given in the problem statement the volume

V = s3----- (1)

And

s = 4x2 + 3--------(2)

Hence,

the volume is obtained by substituting (2) in (1).

We get,

V = (4x2 + 3)3

= 64 x6 + 144x4 + 108x2 + 27

Therefore,

the volume of cube is 64 x6 + 144x4 + 108x2 + 27.

Answer:

Step-by-step explanation:

The side length, s, of a cube is 4x2 + 3. If V = s3, what is the volume of the cube?

Volume = s³

s = 4×2+3

so

(4 × 2  + 3)² =                 (remember PEMDAS)

The distance between the peter's house and John's house is found as √116 units.

For the given question;

Let the coordinates of the John's house be (x₁, y₁).

Let the coordinates of Paul's house M be (x, y) = ( 3, -5).

Let the coordinates of Peter's house be (x₂, y₂) = (5, -4).

Then, by the formula of mid point.

x = (x₁ + x₂)/2

Put the values and simplifying.

x₁ = (2×3) - 5

x₁ = 1

Similarly for the y coordinates.

y = (y₁ + y₂)/2

Put the values and simplifying.

y₁ = (2×-5) - 4

y₁ = -14

Thus, the coordinates of the John's house is found as (1, -14).

Now, the distance between peter's house and john's house is;

d = √(x₁ - x₂)² + (y₁ - y₂)²

Put the values;

d = √(5-1)² + (-4+14)²

d = √(4)² + (10)²

On simplification,

d = √116 units.

Thus, the distance between the peter's house and John's house is found as √116 units.

By solving a quadratic equation we will find two solutions, one is good and that is x = 0.62, and the other is extraneous and is x = -1.62

Here we have the following equation:

ln(x + 2) + ln(2x - 1) = 0

To solve this we need to know two things, first:

ln(a)+ ln(b) = ln(a*b)

ln(1) = 0

Using the first property, we can rewrite:

ln(x + 2) + ln(2x - 1) = ln( (x + 2)*(2x - 1)) = 0

And that can only be equal to zero if:

(x + 2)*(2x - 1) = 1

So we have a quadratic equation:

(x + 2)*(2x - 1) = 1

2x² - x + 4x - 2 = 1

2x² + 3x - 3 = 0

The solutions are:

[tex]x = \frac{-3 \pm \sqrt{3^2 - 4*3*(-3)} }{2*3} \\\\x = \frac{-3 \pm 6.7 }{6}[/tex]

So we have:

x = (-3 + 6.7)/6 = 0.62

x = (-3 - 6.7)/6 = -1.62

The second solution when evaluated in the second term of the equation gives:

ln(2*(-1.62) - 1) = ln(-4.24)

And this is not defined, so x = -1.62 is an extraneous solution.

The linear equation that passes through the anchor points (-3, -38) and (8, 61) is:

y = 9*x - 11

The general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

We know that for a line that passes through two points (x₁, y₁) and (x₂, y₂) can be written as:

a = (y₂ - y₁)/(x₂ - x₁)

Now, in this case we know that our line passes through the points (-3, -38) and (8, 61), then the slope will be:

a = (61 + 38)/(8 + 3) = 9

Replacing that we get:

y = 9*x + b

Now, using one of the points we can find the y-intercept, I will use (8, 61), replacing the values we get:

61 = 9*8 + b

61 = 72 + b

61 - 72 = b

-11 = b

2) C = B - 4.86

Replace C with 6.2.

(6.2) = B - 4.86 can be rewritten as 6.2 + 4.86 = B.

B = 11.06

Add 2.5 to 11.06 and you get 13.56 kg.

If a milk truck delivers 486 dozen gallons of milk to stores in 1 day, then equation to calculate "g",  the number of gallons of milk the milk truck delivers in 1 day, can be written as [g = (486 * 12)]

As per the question statement, a milk truck delivers 486 dozen gallons of milk to stores in 1 day.

We are required to determine the equation that can best express "g", the number of gallons of milk the milk truck delivers in 1 day.

To solve this question, first we need to know what an equation is.

Here, We know that (1 dozen = a set of 12),

Then, [486 Dozen Gallons = (486 * 12)] gallons, which is the total number of gallons of milk the milk truck delivers in 1 day.

On the other hand, the variable "g" can also be used to determine the number of gallons of milk the milk truck delivers in 1 day.

Answer:

There are 20 long tables and 5 round tables y.

Step-by-step explanation:

Given:

long tables x + round tables y = total of 25 tables

8seats ·x +6seats ·y = 190 seats

Find x and y:

x+y= 25 so x= 25-y

8x+6y = 190, we substitute x for 25-y to find y

8(25-y) +6y = 190, we distribute 8 in parenthesis

200 -8y+6y = 190, combine like terms

200 -2y = 190, subtract 200 from both sides

-2y = 190-200, combine like terms

-2y = -10, divide both sides by -2

y = 5

x+y = 25, substitute y for 5

x+5 = 25, subtract 5 from both sides

x= 20

Conclusion:

There are 20 long tables and 5 round tables y.

Step-by-step explanation:

This can be solved without too much calculation

First note that the lope of the graph is negative. If you look at the graph, as x increases, y decreases so that indicates a negative slope

We can safely eliminate the last two options because the coefficient of x in both is +1/4 indicating a positive slope

That leaves the first two for consideration

We can plug in the x, y  values for the given point (4, 3) which lies on the  line and see which of the equations is consistent, i.e whether the LHS and RHS of the equation match

Putting y = 3 and x = 4 in the first equation y - 4 = -1/4(x - 3) gives us
3 - 4 = -1/4(4-3) ??

-1 = -1/4(1) ?

-1 = -1/4? NO

So the correct choice is the second option and we can verify that by plugging in (4, 3) into y - 3 = -1/4(x - 4)

y - 3 = 3 - 3 = 0

x - 4 = 4 - 4 = 0

So 0 = -1/4(0) = 0

which is consistent

When one grain of sand weighs 7×10⁻⁵ g, then there are 9.0 × 10¹⁰ grains of sand in 6300 kg of sand.

Solving a linear equation that comes from the relation:

TV = TU + UV

We will see that the value of x is 1.

I'm answering the question you wrote.

We know that point U is on the line segment TV, then we can write:

TV = TU + UV

This says that the total length of TV is equal to the sum of the two segments in it.

It says:

"the length of segment TV is equal to the sum between the lengths of segments TU and UV"

Here we know that:

TU = 4

UV = 5x

TV = 3x + 6

Then we can write the linear equation:

3x + 6 = 4 + 5x

Answer:

C = $60

Step-by-step explanation:

To calculate monthly charges, a cellphone provider uses the equation: C = 0.25m + 60, with C being dollars and m representing minutes used beyond the ones provided by the plan. Assuming the plan allowed for 60 minutes, what would the charge be for a client that used 55 minutes? Put your answer in terms of dollars.

The customer used 55 minutes and did not max out the phone plan, and therefore does not pay any over charges of m.

C = 0.25m + 60 when m = 0

C = 0.25m + 60

C = 0.25(0) + 60

C = 0 + 60
