Answer:

FALSE

Step-by-step explanation:

  F = (N - O)/R     Multiply both sides by R

RF = N – O          Divide both sides by F

 R = (N – O)/F

FALSE. The given solution is incorrect.

Final answer:

The statement provided is false. The correct formula for vascular resistance R in terms of blood flow F, inlet pressure N, and outlet pressure O should be R = (N - O) / F.

Explanation:

The statement is false. The correctly solved equation for vascular resistance R, based on the formula F = (N - O) / R where F is blood flow rate, N is the pressure at the inlet, O is the pressure at the outlet, would be R = (N - O) / F. If we isolate R in the equation by multiplying both sides by R and dividing by F, we would get R = (N - O) / F, not R = F + O - N as incorrectly stated in the question.

To further understand the relationships among the factors affecting blood flow, the Poiseuille's equation plays a significant role. This equation includes critical variables like the radius (r) to the fourth power, vessel length (λ), and viscosity (n) of the fluid. Changes in these variables can significantly affect blood flow and resistance within the vascular system.

To find the volume of a rectangular prism, multiply the length, width, and height. The formula is V = l * w * h.

To find the volume of a rectangular prism, you need to multiply the length, width, and height of the prism.

The formula for the volume of a rectangular prism is: V = l * w * h.

So, to find the volume of a rectangular prism, you need to know the measurements of its length (l), width (w), and height (h) in the same unit of measurement.

Multiply these values together to find the volume in cubic units (such as cubic centimeters or cubic meters).

For example, if a rectangular prism has a length of 5 centimeters, a width of 3 centimeters, and a height of 2 centimeters, you would calculate the volume as follows: V = 5 cm * 3 cm * 2 cm = 30 cm³.

The volume of the rectangular prism, obtained from the product of the known face area and the width is 11 2/3 cube units

Volume = 11 2/3 units³

The details of the steps used to find the volume of the prism can be presented as follows;

The dimensions of the rectangular prism includes a face area and the width of the prism

Area of a face of the rectangle = 3 1/3 square units

Width of the rectangular prism = 1 2/5 units

Area of a rectangular prism = Length × Width × Height

The length and the height of the rectangular prism form the face with the known area of 3 1/3 square units

Therefore; Area of a rectangular prism = Width × Area of the vertical face perpendicular to the width of the rectangular prism

Area of a rectangular prism = 1 2/5 units × 3 1/3 square units

1 2/5 units × 3 1/3 square units = (7/2) × (10/3)

(7/2) × (10/3) = 70/6

70/6 = 11 2/3

Area of the rectangular prism is 11 2/3 units³

The oldest brother is 20 years old.  PLEASE GIVE BRAINLIEST!!!

Step-by-step explanation:

Youngest = 5x - (x+4) = 60                           Oldest = 5x - 60

                   5x - 1(x+4) = 60                                5(16) - 60 =

                   5x - x - 4 = 60                                  80 - 60 = 20

                   4x - 4 = 60

                    4x = 60 + 4

                  4x = 64    

                    x = 64 ÷ 4    x = 16

Youngest = 16

Middle = 18

Oldest = 20

Step-by-step explanation:

⭕ 11\16= %

⭕ 11÷16= 68.75%

⭕ 68.75%

To convert a fraction to a percentage, we would multiply the fraction by 100%, and the result would be the percentage.

In this case:

11/16 x 100%

=0.6875 x 100%

=68.75%

Therefore the answer is 68.75%

Hope it helps!

Answer:

A. 50%; This percentage is lower than expected in a normal distribution

Answer:

A) 50%; This percentage is lower than expected in a normal distribution.

Step-by-step explanation:

Data points given:

55, 54, 66, 38, 53, 56, 57, 66, 45, 65

n = 10

The mean for the data points:

[tex] \frac{55+54+66+38+53+56+57+66+45+65}{10} [/tex]

Mean = 55.5

Standard deviation of data points:

[tex] = \sqrt{\frac{55-55.5)^2+(54-55.5)^2+(66+55.5)^2+(38-55.5)^2+(53-55.5)^2+(56-55.5)^2+(57-55.5)^2+(66-55.5)^2+(45-55)^2+(65-55)^2}{10}} [/tex]

= 8.59

Now let's find the data points that lie between 64.09 i.e (55.5 + 8.59) and 46.91 i.e (55.5-8.59)

We can see that 5 data points lie between 64.09 and 46.91 which are { 55,54,53,56,57}

The correct option is A, which states that 50% percentage is lowee than expected.

Step-by-step explanation:

Point O is the midpoint of segment AB. Through point O is drawn a line OX perpendicular to AB. Consider two triangles AOX and BOX. These triangles are right triangles, because OX is perpendicular to AB. In these triangles:

Thus, [tex]\triangle AOX\cong \triangle BOX[/tex] by LL theorem.

Congruent triangles have congruent corresponding sides, then AX=BX. This means that point X is equidistant from points A and B.

Answer:

Side EH

Step-by-step explanation:

Side AD is proportional to side EH. If you look at ABCD, and compare it to EFGH, the ends of the name, AD, correspond with the ends of the other, EH.

Side AD of trapezoid ABCD is proportional to side EH of trapezoid EFGH due to the properties of similar geometric figures, where corresponding sides of similar shapes are in proportion.

The question asks which side of trapezoid EFGH is proportional to side AD of trapezoid ABCD, given that the two trapezoids are similar. In similar figures, corresponding sides are proportional. Therefore, if side AD of trapezoid ABCD corresponds to side EH of trapezoid EFGH, then these sides are proportional to each other.

Since we are discussing proportions and similarity of shapes, particularly trapezoids, we can reference several mathematical concepts. By the AAA theorem, which stands for angle-angle-angle, we know that if two or more corresponding angles in two figures are equal, then the figures are similar and the sides opposite these angles are proportional. Also, the proportions of corresponding sides can be determined using theorems regarding triangles and trapezoids.

We conclude that side AD is proportional to side EH because of the properties of similar geometric figures.

Step by Step Explanation:

16. x - 4 = 4

Isolate the variable (x). Note the equal sign, what you do to one side, you do to the other. Add 4 to both sides:

x - 4 (+4) = 4 (+4)

x = 4 + 4

x = 8

17. a/4 = 4

Isolate the variable (a). Note the equal sign, what you do to one side, you do to the other. Multiply 4 to both sides:

(a/4)(4) = (4)(4)

a = (4)(4)

a = 16

18. y * 20 = 30

Isolate the variable (y). Note the equal sign, what you do to one side, you do to the other. Divide 20 from both sides.

(y *20)/20 = (30)/20

y = 30/20

y = 3/2 or 1.5

19. x/5 = 20

Isolate the variable (x). Note the equal sign, what you do to one side, you do to the other. Multiply 5 to both sides

(x/5)(5) = (20)(5)

x = (20)(5)

x = 100

    Statement 3 as well as statement 1 are true

Step-by-step explanation:

Answer:

1.function 1 has a greater rate of change than function 2

3. Function 1 has a greater y-intercept than function 2

Step-by-step explanation:

Using the table we can find the slope using

m = (y2-y1)/ (x2-x1)

m = (29-5)/ (8-0)

     = 24/8

    = 3

The rate of change for the table is 3

The y intercept is (0,5)  

Using the graph  (0,-1)  and (2,0)

m = (y2-y1)/ (x2-x1)

m = (0--1)/ (2-0)

     = (0+1)/2

    = 1/2

The y intercept is (0,-1)

Since 3>1/2 , function 1 has a greater rate of change than function 2

Since 5>-1, function 1 has a greater y-intercept than function 2

Well, since they are lined up correctly already, you can combine the like terms and get 4x + 3y = 2.

Is that all you wanted?

Answer:

A) 3x - y = -5

B) x + 4y = 7

Whenever you have to solve for 2 unknowns, you need 2 equations.  (These are called solving simultaneous equations.)

Perhaps the easiest way to solve these is by the elimination of variables.

Looking at Equation A) we see that if we multiply it by 4, and add it to equation B), the "y" variable will be eliminated.

Multiplying equation A) by 4 we get

A) 12x - 4y = -20   then adding this to B)

B) x + 4y = 7   we get

EDITD TO CORRECT**************************************************

13x = -13

x = -13 / 13= -1

Then we can get x = -1 and insert it into either equation.  (Let's choose B)

B) -1 + 4y = 7

B) 4y = 8

y = 2

*******************************************************************************************

For a double-check we can insert x = -1 and y = 2 into either equation.  (Let's choose equation B)

B)  -1 + 4 * 2 = 7

B)  -1 + 8 = 7

And since -1 + 8 DOES equal 7, we know that we have solved for "x" and "y" correctly!

the answer is 9.9

Step-by-step explanation:

12.1-2.2=9.9

The elevation of Tammy’s house is greater than the elevation of the ocean’s surface at 2 p.m. will be 9.9.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that, on Tuesday at 2 p.m., the ocean’s surface at the beach was at an elevation of 2.2 feet. Winston’s house is at an elevation of 12.1 feet. The elevation of his friend Tammy’s house is 3 1/2 times the elevation of Winston’s house.

We have to find the elevation of Tammy’s house greater than the elevation of the ocean’s surface at 2 p.m.

Suppose the greater is the elevation of Tammy’s house than the elevation of the ocean’s surface at 2 p.m be x,

x=12.1-2.2

x=9.9

Thus, the elevation of Tammy’s house is greater than the elevation of the ocean’s surface at 2 p.m. will be 9.9.

a = 1

b = 12

12^2 = 144

Answer:

The value of [tex]c =144[/tex] makes [tex]x^{2}-24x+c[/tex] perfect square.

Step-by-step explanation:

We have to make [tex]x^{2}-24x+c[/tex]

Since, Perfect square formula: [tex]a^{2} - 2ab + b^{2}=(a-b)^{2}[/tex]

Re-write [tex]x^{2}-24x+c[/tex] as,

[tex]x^{2}-2\times 12x+c[/tex]

Compare above with [tex]a^{2} - 2ab + b^{2}[/tex]

Where a = x  and b= 12

so, [tex]b=12[/tex]

⇒ [tex]c =12^{2}=144[/tex]

Hence, [tex](a-b)^{2}=(x-12)^{2}[/tex]

Therefore, the value of [tex]c =144[/tex] makes [tex]x^{2}-24x+c[/tex] perfect square.

Answer: 35 liters

Step-by-step explanation:

Volume of 1 marble = 0.04 Liters

volume of 50 marbles = 50 x 0.04 liters = 2 liters

volume of water added =  33 liters ( Given)

Volume of tank = Volume of water + Volume of 50  marbles

                          =      33 liters + 2 liters

                          =    35 liters

Answer: z < 4

z+4 > 2z

z+4-z > 2z-z ..... Subtract z from both sides

4 > z

z < 4

So the solution set for z is any number that is less than 4, which could be something like z = 2 or z = 3.

The 3 foot stick broken in a 5:7 ratio results in two pieces measuring 1.25 feet and 1.75 feet, respectively.

The question involves a 3 foot stick that is broken into two pieces with a ratio of 5:7.

To find the lengths of the two pieces, we first add the parts of the ratio together, which gives us 12 parts in total.

Since the whole stick is 3 feet long, each part of the ratio represents \(\frac{3 feet}{12 parts}\) or \(\frac{1}{4} foot\) per part.

Thus, the length of the smaller piece is 5 parts (\(5 \times \frac{1}{4} = \frac{5}{4} feet\) or 1.25 feet) and the length of the larger piece is 7 parts (\(7 \times \frac{1}{4} = \frac{7}{4} feet\) or 1.75 feet).
