How to solve this:

1:     7200/24 = x/1

2:    7200/24 = 300/1

3:     300 L of blood per hour

We know that an average is 7200 for heart pumps so we divide 7200 by 24 hours = x/1  

Second step is the same 7200 divided by 24 = 300/1

So the correct answer is 300. 300 L of blood per hour.

Answer: 300 L of blood per hour.

Hope this helps.

The rate of change in the volume of blood is 300 liters per hour.

A rate is a type of ratio that compares two values with distinct units. A rate is expressed as a fraction.

The volume of blood pumped by the teenager's heart is expressed as a rate of change in volume per hour.

Rate of change of volume of blood = volume of blood/time

= 7200 L /24

Apply the division operation, and we get

= 300 L/hour

The teenager's heart changes blood volume at a pace of 300 liters per hour. This means that his or her heart is pumping 300 liters of blood every hour.

Answer:

Step-by-step explanation:

You have to use the distance formula to find that distance.  The formula is:

[tex]d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/tex]

Let's call the first point x1, y1 (4, -1) and the second point x2, y2 (0, -2). Plugging into our formula then gives us this:

[tex]d=\sqrt{ (0-4)^2+(-2-(-1))^2}[/tex]

which simplifies to

[tex]d=\sqrt{(-4)^2+(-1)^2}[/tex] which is

[tex]d=\sqrt{17}[/tex] ≈ 4.123 units

Answer:

6 units cubed

Step-by-step explanation:

The volume will simply be the volumes of all the little cubes added together.

The volume of a cube is V = s³, where s is the side length. Here, it's 1/2, so:

V = s³ = (1/2)³ = 1/8 units cubed

We have 48 such cubes, so multiply 1/8 by 48 to get the total volume:

48 * (1/8) = 6 units cubed

Thus, the prism is 6 units cubed.

Answer:

y = - [tex]\frac{4}{5}[/tex] x + [tex]\frac{2}{5}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 4y = 5x + 3 into this form by dividing the 3 terms by 4

y = [tex]\frac{5}{4}[/tex] x + [tex]\frac{3}{4}[/tex] ← in slope- intercept form

with slope m = [tex]\frac{5}{4}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{5}{4} }[/tex] = - [tex]\frac{4}{5}[/tex] , thus

y = - [tex]\frac{4}{5}[/tex] x + c ← is the partial equation

To find c substitute (3, - 2) into the partial equation

- 2 = - [tex]\frac{12}{5}[/tex] + c ⇒ c = - 2 + [tex]\frac{12}{5}[/tex] = [tex]\frac{2}{5}[/tex]

y = - [tex]\frac{4}{5}[/tex] x + [tex]\frac{2}{5}[/tex] ← equation of perpendicular line

Answer: Garden = 36 ft², Path = 64 ft²

Step-by-step explanation:

Path is 3 ft wide ON EACH SIDE of the garden

Garden + 2(Path) = 10 ft   --> Garden = 6 ft wide.

Since the garden is a square, Area = 6² = 36

Garden + 2(Path) = 10 ft

Since the Garden + Path form a square, Area = 10² = 100

Area of Garden + Area of Path = Total Area

         36             + Area of Path =      100

                              Area of Path =      64

Answer:

x = 32

Step-by-step explanation:

Three angles have been shown in the figure which are located at a point of a straight line.

By the property of angles on a straight line,

Sum of the angles shown = 180°

(3x - 20)° + 30°+ (2x + 10)° = 180°

(3x + 2x) + ( -20 + 30 + 10) = 180

5x + 20 = 180

5x = 180 - 20

5x = 160

x = [tex]\frac{160}{5}[/tex]

x = 32

Therefore, x = 32 will be the answer.

Answer:

[tex]x = 32 \: \: degrees[/tex]

Step-by-step explanation:

Angels in a straight line =180°

[tex]3x - 20 + 30 + 2x + 10 = 180 \\ 5x + 20 = 180 \\ 5 x = 180 - 20 \\ 5x = 160 \\ \frac{5x}{5} = \frac{160}{5} \\ x = 32[/tex]

Answer:

x = 0.8

Step-by-step explanation:

What this question asks us is that what value of x solves the first inequality but does not work for the second

Let’s solve the first inequality;

4x > 3.2-0.8

4x > 2.4

x > 2.4/4

x > 0.6

Now all values of x which is greater than 0.6 is a solution to the first inequality

Now to the second, we have;

-6 > -5x -1

Using the range of values from the first inequality;

if we say x = 0.8

Then

-6 > -5(0.8) -1

-6 > -4-1

-6 > -5

But this is not right in the real sense as actually

-5 > -6

So we can confirm that 0.8 is a solution that works for the first inequality but doesn’t work for the second

Complete Question:

The perimeter of triangle XYZ is 24 units. Triangle X Y Z is shown. The length of X Y is 3 and the length of Y Z is 11. Angle Y X Z is 102 degrees What is the area of triangle XYZ? Round to the nearest tenth of a square unit. Trigonometric area formula: Area 14.7 square units 14.9 square units 15.0 square units 15.3 square units

Answer:

14.7 square units

Step-by-step Explanation:

Given the triangle shown in the figure attached below, having the following measures:

<YXZ = 102°

Length of XY = z = 3

Length of YZ = x = 11

Length of XZ = y = ?

Perimeter of ∆XYZ = x+y+z = 24 units

Length XZ = y, would be 11+y+3 = 24

14+y = 24

y = 24 - 14

Therefore, y = 10

==>Required:

Area of ∆XYZ to the nearest tenth of a square unit

==>Solution:

Using the Trigonometric area formula, area of ∆XYZ = ½(yz)sin X

Plug in values for x, y, and sin X:

Area of ∆ XYZ = ½×10×3×sin 102

= ½×30×0.9782

= 15 × 0.9782

= 14.673

Area of triangle XYZ approximated to the nearest tenth = 14.7 square units

Answer:

[tex]y - 5 = -4(x-5)[/tex]

Step-by-step explanation:

Given

Line coordinates: (5,5)

Perpendicular slope = [tex]\frac{1}{4}[/tex]

Required

Find the point slope form of the line

First, the slope of the line has t be calculated;

Given that two lines are perpendicular;

The relationship between there slopes is given as [tex]m_1.m_2 = -1[/tex]

Let m_2 represent the slope of the second line;

such that [tex]m_2 = \frac{1}{4}[/tex]

So;

[tex]m_1 * \frac{1}{4} = -1[/tex]

Multiply both sides by 4

[tex]m_1 * \frac{1}{4} * 4 = -1 * 4[/tex]

[tex]m_1 = -1 * 4[/tex]

[tex]m_1 = -4[/tex]

Now, the equation of the line can be calculated using slope formula;

[tex]m = \frac{y - y_1}{x- x_1}[/tex]

Where

[tex](x_1,y_1) = (5,5)\\m_1 =m = -4[/tex]

So; [tex]m = \frac{y - y_1}{x- x_1}[/tex] becomes

[tex]-4 = \frac{y - 5}{x- 5}[/tex]

Multiply both sides by x - 5

[tex]-4(x-5) = \frac{y - 5}{x- 5} * (x-5)[/tex]

[tex]-4(x-5) = y - 5[/tex]

Reorder

[tex]y - 5 = -4(x-5)[/tex]

Hence, the line in point-slope form is [tex]y - 5 = -4(x-5)[/tex]
