The average adult breathes in about 37 L of air every 5 minutes. What is the rate of change of volume of air per minute?

Answers

Answer 1

Answer:

7.4 L per minute

Step-by-step explanation:

Volume of air = 37 L

Time = 5 minutes

What is the te of change of volume of air per minute?

Rate of change of volume of air per minute = Volume of air / Time

= 37 L / 5 minutes

= 7.4 L/minutes

That is, the rate of change of volume of air = 7.4 L per minute

The three angles of a triangle measure x+37, 90, and x+67. Find the measurement of the smallest angle in degrees.

Answers

Answer:

The smallest angle in the triangle is 30°

Step-by-step explanation:

You can solve this by including the fact that the sum of the angles in the triangle has to be 180 degrees. We're given values describing the angles, so we can simply add them together, say the equal 180, and solve for x:

[tex](x + 37) + 90 + (x + 67) = 180\\2x + 37 + 90 + 67 = 180\\2x + 194 = 180\\2x = 180 - 194\\2x = -14\\x = -7[/tex]

The smallest angle then is x + 37, or 37 - 7, giving us 30°

If three angles of a triangle measure x+37, 90, and x+67. Then 30 degrees is the measurement of the smallest angle in degrees.

What is Triangle?

A triangle is a three-sided polygon that consists of three edges and three vertices.

Given,

The three angles of a triangle measure x+37, 90, and x+67.

We need to find the measurement of smaller angle.

From angle sum property we know that the sum of three angles is equal to 180 degrees.

x+37+90+x+67=180

2x+194=180

Subtract 194 from both sides

2x=180-194

2x=-14

Divide both sides by 2.

x=-7

Substitute the value of x in smallest angle

x+37

-7+37=30

Hence the measurement of the smallest angle in degrees is 30

Answer:57

Step-by-step explanation:

When you divide a unit fraction by a whole number greater that 1, the quotient is always smaller than the unit fraction being divided. Why is this true? Use an example to support your answer.

Answers

Answer:

The servings that each of your friend received which is 1/8 is the quotient. And the servings that each of your friends got is smaller compared to the half of the round chocolate cake. Therefore, when dividing a unit fraction by a whole number, the quotient is always a unit fraction which is less than the dividend.

The statement is true because when you divide a unit fraction by a whole number greater than 1, you are essentially dividing a quantity that is smaller than 1 by a quantity that is greater than 1.

What is a fraction?

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

We have two types of fractions.

Proper fraction and improper fraction.

A proper fraction is a fraction whose numerator is less than the denominator.

An improper fraction is a fraction where the numerator is greater than the denominator.

Example:

1/2, 1/3 is a fraction.

3/6, 99/999 is a fraction.

1/4 is a fraction.

We have,

Let's consider dividing the unit fraction 1/3 by the whole number 2:

= 1/3 ÷ 2

= 1/3 x 1/2

= 1/6

We can see that the resulting quotient, 1/6, is smaller than the original unit fraction of 1/3.

This is because when we divide 1/3 by 2, we are essentially dividing 1 unit of 1/3 by 2 units.

This means that each of the resulting units is smaller than the original unit of 1/3 since it has been divided into more pieces.

In the example above, each resulting unit is 1/6, which is smaller than the original unit of 1/3.

This relationship holds true for any unit fraction and any whole number greater than 1.

The resulting quotient will always be smaller than the original unit fraction being divided.

Thus,

The statement is true because when you divide a unit fraction by a whole number greater than 1, you are essentially dividing a quantity that is smaller than 1 by a quantity that is greater than 1.

Calcula la longitud en YARDAS de
un trayecto A que mide 100 metros
y la longitud en
YARDAS de un trayecto B que mide 18.50

Answers

Answer:

Las longitudes solicitadas en yardas son:

Trayecto A = 109.361 yardas.Trayecto B = 20.231785 yardas.

Step-by-step explanation:

Para hacer la conversión de unidades que requieres en el ejercicio, debes saber que:

1 metro = 1.09361 yardas

Con ese factor de conversión tú puedes hacer reglas de tres para calcular las medidas que requieres. En el caso del trayecto A:

Si:

1 metro = 1.09361 yardas100 metros = X

Entonces:

[tex]x=\frac{100m *1.09361yardas}{1m}[/tex]

Cancelamos metros y obtenemos:

x = 100 * 1.09361 yardasx = 109.361 yardas

En este caso, el trayecto A en yardas corresponde a 109.361 yardas. El mismo procedimiento puede aplicarse para el trayecto B:

Si:

1 metro = 1.09361 yardas18.50 metros = X

Entonces:

[tex]x = \frac{18.50m*1.09361yardas}{1m}[/tex]

Cuando se cancelan los metros se obtiene:

x = 18.50 * 1.09361 yardasx = 20.231785 yardas

Así, el trayecto B en yardas corresponde a 20.231785 yardas.

Last year there were m members in a photography club. This year the number of
members has increased by 10%. The expression m + 0.1m represents the number of
members in the club this year. What is this expression written in simplest form?

Answers

Answer:

m + 10/100(m)

Step-by-step explanation:

Last year there were m members in a photography club.This year the number of members has increased by 10%m + 0.1m represents the number of members in the club this year.

So m represents the number of members in the club last year.

A 10% increase of the members = [tex]\frac{10}{100} * m[/tex] = 0.1m

Hence the number of members in the club this year = m + 0.1m

(3 -1) y=1/3x-3 write an equation of the line that passes through the given point and is parallel to the given line

Answers

Answer:

[tex]y = 1/3x-2[/tex]

Step-by-step explanation:

General line equation:

[tex]\frac{y-y_{1}}{x-x_{1}} = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]

Or

[tex]y = a.x + b\\a = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\b = y_{1} - a.x_{1}[/tex]

where a is the slope and b is vertical displacement.

For a line to be parallel to another, they both have to have the same slope, therefor, the parallel line's slope is 1/3.

By substituting the given point and a = 1/3 in above equation for b, b is equal to -2. Therefore,

[tex]y = 1/3x - 2[/tex]

On a coordinate grid, point P is at (5, 2) and point R is at (−3, −4). Points Q and S are a reflection of both points across the x-axis. What are the coordinates of Q and S? (5 points) a Q(−5, 2), S(3, −4) b Q(−5, −2), S(3, 4) c Q(5, −2), S(−3, 4) d Q(−5, 2), S(−3, 4)

Answers

Answer:

The correct option is;

c. Q(5, -2), S(-3, 4)

Step-by-step explanation:

In a reflection of a preimage across the x-axis of a point with coordinates (x, y), the value and sign of the x-coordinate of the image does not change while the value of the y-coordinate of the image is the same as the value of the y-coordinate of the pre-image, but with opposite sign

Therefore, we have

The coordinate of the preimage before the reflection across the x-axis = (x, y)

The coordinate of the image after the reflection across the x-axis = (x, -y)

Therefore, for the preimage point P(5, 2) before the reflection, we have the coordinate of the image point as Q(5, -2)

Similarly, or the preimage point R(-3, -4) before the reflection, we have the coordinate of the image point as S(-3, 4).

The correct option is therefore, Q(5, -2), S(-3, 4).
