Answer:

N(2,3)

Step-by-step explanation:

According to the Question,

Thus, M(x,y) = (-1+7)/2 , (3-3)/2 ⇒ M(3,0)

Thus. N(a,b) = (1+3)/2 , (6+0)/2  ⇒ N(2,3)

Let the time = X

Distance = Rate times time

Level roads = 18x

Hills = 10x

Total is 98 miles

18x+10x = 98

Add:

28x = 98

Divide both sides by 28:

x = 3.5

She spent 3.5 hours on each part

Total time = 3.5 + 3.5 = 7 hours

Given:

Fixed cost = $300

Variable cost = $75 on each supply

Revenue = $125 on each horse.

To find:

The number of horses for break even.

Solution:

Let x be the number of horses.

The fixed cost is $300 and the variable cost is $75 on each supply. So, the cost function is:

[tex]C(x)=300+75x[/tex]

The revenue from each horse is $125. So, the revenue function is:

[tex]R(x)=125x[/tex]

On break even, the revenue and cost are equal.

[tex]R(x)=C(x)[/tex]

[tex]125x=300+75x[/tex]

[tex]125x-75x=300[/tex]

[tex]50x=300[/tex]

Divide both sides by 50.

[tex]x=\dfrac{300}{50}[/tex]

[tex]x=6[/tex]

The number of horses for break even is 6.

Therefore, the correct option is D.

Answer:

  4.  n = 4

  5.  P(A|B) = 0.75

Step-by-step explanation:

4. The coefficient of x will depend on n. The expansion is ...

  (5 +nx)^2(1 +3/5x)^n = (25 +10nx +n^2·x^2)(1 +3/5nx +...)

So, the x-term of the expansion is ...

  25(3/5nx) +(10nx)(1) = 25nx

The problem statement tells us that is 100x, so we have ...

  25nx = 100x

  n = 100x/(25x) = 4 . . . . . divide by the coefficient of n

The value of n is 4.

5. For the conditional probability formula, we need to know P(A∩B).

  P(A∩B) = P(A) +P(B) -P(A∪B)

  P(A∩B) = 0.5 +0.4 -0.6 = 0.3

Then the conditional probability is ...

  P(A|B) = P(A∩B)/P(B) = 0.3/0.4

  P(A|B) = 0.75

1. The measurements you need to find the volume of a cylinder are the radius of the base of the cylinder and the height of the cylinder.

2. The radius is 4

3. The 3D shape will form a full cylinder.

4. To calculate the  volume of a cylinder we use the formula V = πr²h which is = π(4²)(2) = 3.14 × 16 × 2 = 100.48 cm³

5. The formula for a refraction will be (πr²h) / 2

6. From the formula in part E, the approximate volume of a refraction is (3.14 × 4² × 2)/ 2 = 50.24 cm³

If you have been givn the volume of a cylinder and its height, you can use the formula for the volume of a cylinder to solve for the radius. Rearange the formula to r = sqrt(V / (πh)).

If you know the surface area of a given cylinder and height, you can find the radius using the formula for cylinder surface area (A = 2rh + 2r2). Rewrite the formula as r = (A - 2h) / (2.

Step-by-step explanation:

Answer:

r = 9.61 cm

Step-by-step explanation:

Volume of a rectangular box = length × width × height

= 21.5 cm × 13.5 cm × 6 cm

= 1,741.5 cm³

Volume of a rectangular box = 1,741.5 cm³

Since,

Volume of a rectangular box = Volume of a circular box

Then,

1,741.5 cm³ = Volume of a circular box

Volume of a circular box = πr²h

1,741.5 cm³ = 3.14 * r² * 6 cm

1,741.5 = 18.84r²

r² = 1,741.5/18.84

r² = 92.436305732484

r = √92.436305732484

r = 9.6143801533163

  log4(2) = 0.5000

Step-by-step explanation:

You are being asked to figure out how to make the value 2 from the values 6 and 3. Your familiarity with arithmetic facts tells you ...

  2 = 6/3

Taking logs base 4, you have ...

  log4(2) = log4(6/3) = log4(6) -log4(3)

  log4(2) = 1.2925 -0.7925

  log4(2) = 0.5000

This is consistent with your knowledge of factors of 4:

  √4 = 4^(1/2) = 2

Answer:

y-3 = -2/9(x+1)

Step-by-step explanation:

Here, we want to find the standard equation

Generally, we have the equation as;

y = mx + b

where m is the slope of the line and b is the y intercept

To find the slope, we use the slope equation

m =y2-y1/x2-x1

m = (3-1)/(-1-8) = 2/-9 = -2/9

So to write in point slope form, we can use any of the two points

We have;

y-y1 = m(x-x1)

using (-1,3)

y-3 = -2/9(x+1)

Given:

Scott can run 20 km in 85 minutes.

To find:

How long will it take Scott to run 52 km?

Solution:

Let x be the number of minutes it will take him to run 52 km.

We know that,

[tex]Speed=\dfrac{Distance}{Time}[/tex]

Using this formula, we get

[tex]Speed=\dfrac{20}{85}[/tex]           ...(i)

[tex]Speed=\dfrac{52}{x}[/tex]             ...(ii)

Equating (i) and (ii), we get

[tex]\dfrac{20}{85}=\dfrac{52}{x}[/tex]

[tex]20\times x=52\times 85[/tex]

[tex]20x=4420[/tex]

Divide both sides by 20.

[tex]x=\dfrac{4420}{20}[/tex]

[tex]x=221[/tex]

Therefore, it will take 221 minutes to run 52 km.

Answer:

[tex]5[/tex]

Step-by-step explanation:

Segments are named by their endpoints. Therefore, segment PQ will have endpoints P and Q. The length of the segment is equal to the distance between these points.

To find the distance between P and Q given their coordinates, use the distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Let:

[tex]P(-2, 7)\implies (x_1, y_1),\\Q(1, 3)\implies (x_2, y_2)[/tex]

The distance between these points is equal to:

[tex]d=\sqrt{(1-(-2))^2+(3-7)^2},\\d=\sqrt{3^2+(-4)^2},\\d=\sqrt{9+16},\\d=\sqrt{25},\\d=\boxed{5}[/tex]

Answer:

[tex]5[/tex]

Step-by-step explanation:

This problem gives one the following points on a line: ([tex]P(-2,7)[/tex]), and ([tex]Q(1,3)[/tex]). The problem asks one to find the distance between the two points. The formula to find the distance between two points on a coordinate point is the following,

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Substitute the given values in and solve for the distance;

[tex]D=\sqrt{(-2)-(1))^2+((7)-(3))^2}[/tex]

Simplify,

[tex]D=\sqrt{(-2)-(1))^2+((7)-(3))^2}\\\\D=\sqrt{(-3)^2+(4)^2}\\\\D=\sqrt{9+16}\\\\D=\sqrt{25}\\\\D = 5[/tex]

Answer:

Step-by-step explanation:

Substitute the 4x for the y in second equation.

Basically setting them equal to each other because the both have 'y='

4x = 8x - 36

-4x  = -36 (subtract 8x from both sides)

x = 9         (divide by -4, both sides)

y = 4(9)     (Substitute the x value into first equation)

y = 36

Use the formula below to calculate the surface area

SA = 2*(LW+LH+WH)

SA = 2*(5*8+5*3+8*3)

SA = 2*(40+15+24)

SA = 2*(79)

SA = 158 square feet

So if you had 158 square feet of wrapping paper, then you can cover this entire 3D box without any gaps or overlaps. The paper can be folded over the box, or you can cut/glue the pieces on, but make sure there isn't any leftover scraps of paper.

A rectangular prism is shaped like a pyramid, but the base is longer in one direction than the other. i.e. a rectangle.  

A cross section of a shape is the new face that is formed when you cut a shape into two pieces with a straight cut. The problem tells us that the cross section is parallel to the base of the prism, therefore if the prism is placed on a flat surface with the base facing down, then we would be cutting horizontally.

The new face that is created on the shape after the cut, would be a rectangle due to the shape of the base.
