What is the quotient of 1.728 x 109 and 4.8 x 106 expressed in scientific notation?

Answer:

$10.00

Step-by-step explanation:

Answer: A

Step-by-step explanation:

The contrapositive of a statement is logically equivalent to the original statement.

Only the arrangement and order Is different else all are similar

in first method Kiran created a table which produces all values in the order [1,6] to H and T.

In second method Priya created a flow chart type tree diagram which produces all values in order H and T to [1,6]

So they both produce same answers as both are like inverses of each other ,

If you try to understand then think about relations

So they are ought to form same values just in different order .

#2

Second method is more applicable as its more understandable and easier

Answer:

[tex]\displaystyle \frac{\pi}{3}[/tex]  radians

Step-by-step explanation:

As an equilateral triangle has all angles congruent to each other, each angle is measured 60°

To convert from degrees to radians, we multiply by π/180

Hence, [tex]\displaystyle 60^\circ*\frac{\pi}{180}=\frac{60\pi}{180}=\frac{\pi}{3}[/tex]

Answer: Mean=4.5

Median=5.5

Step-by-step explanation:

MEAN= Add all of the numbers together then divide by 18 to get 4.5

Median=To find the median, first order your data. Then calculate the middle position based on n, the number of values in your data set. If n is an odd number, the median lies at the position (n + 1) / 2. If n is an even number, the median is the mean of the values at positions n / 2 and (n / 2) + 1. This should get you 5.5

To determine the maximum number of pens he can buy, we need to consider the total discount of $70 and the cost of each pen, which is $9.

Assume he buys an "x" number of pens.

The total discount he receives can be calculated by multiplying the number of pens by the cost of each pen:

$9x

Based on, the shopkeeper agrees to give him a total discount of $70, so we have the equation:

$9x = $70.

To determine the maximum number of pens he can buy, we need to solve for "x".

Dividing both sides of the equation by $9:

x = $70 / $9.

x= 7.77.

Therefore, the maximum number of pens he can buy is 7.

Answer:

-0.7071.

Step-by-step explanation:

The value of function sin 315 is -1/2.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Sin 315 degrees can be found by using the unit circle.

The unit circle is a circle with the radius of one centered at the origin of a coordinate plane.

Every point on the unit circle is a point that is one unit away from the origin.

The unit circle is used to help find the exact values of the trigonometric functions at specific angles.

The angle 315 degrees is in the fourth quadrant of the unit circle, so the x-coordinate is negative and the y-coordinate is negative.

Using the x-coordinate, we can calculate the sine to be -1/2.

Hence, the value of function sin 315 is -1/2.

The concentration of the hydronium ions in the milk is 5.011×10⁻⁴ if  the container of orange juice has a pH of 3.3.

The pH of a solution is a measurement of the concentration of hydrogen ions in the solution, as well as its acidity or alkalinity. Normally, the pH scale ranges from 0 to 14.

We have:

A container of orange juice has a pH of 3.3.

The pH value = 3.3

[tex]\rm pH = -log[H_3O^+][/tex]

[tex]\rm 3.3 = -log[H_3O^+][/tex]

Removing log:

[tex]\rm 10^{-3.3}=[H_3O^+][/tex]

[tex]\rm [H_3O^+] = 5.011\times10^{-4}[/tex]

Thus, the concentration of the hydronium ions in the milk is 5.011×10⁻⁴ if  the container of orange juice has a pH of 3.3.

Therefore, the system of equations that can be used to model this situation is h= 5 + 24t -16t^2.

The equations that were given in the system above are :

h = 18 + 1.5t

h = 5 + 24t - 16t^2

Note that:

The rate of Speed = distance divided by time

Since Speed = 1.5ft/s

Distance = 18ft

To know the time which was not given, the equation will be:

1.5ft/s = 18ft/t

1.5t=18

The equation to know height h= 18 + 1.5t

Since Graham moved another 5ft  along with a velocity of 24ft/s

Therefore, the system of equations that can be used to model this situation is h= 5 + 24t -16t^2 and as such, option A is correct.

m∠B = 70.0° (nearest tenth)

Step-by-step explanation:

Sine Rule for Angles

[tex]\sf \dfrac{\sin A}{a}=\dfrac{\sin B}{b}=\dfrac{\sin C}{c}[/tex]

(where A, B and C are the angles and a, b and c are the sides opposite the angles)

Given:

Substituting the given values into the formula to find m∠C:

[tex]\implies \sf \dfrac{\sin 40^{\circ}}{13}=\dfrac{\sin C}{19}[/tex]

[tex]\implies \sf \sin C=\dfrac{19\sin 40^{\circ}}{13}[/tex]

[tex]\implies \sf C=\sin^{-1}\left(\dfrac{19\sin 40^{\circ}}{13}\right)[/tex]

[tex]\implies \sf m \angle C=69.96086904^{\circ}[/tex]

Interior angles of a triangle sum to 180°

[tex]\implies \sf m \angle A+ m \angle B+m \angle C=180^{\circ}[/tex]

[tex]\implies \sf 40^{\circ} + m \angle B+69.960...^{\circ}=180^{\circ}[/tex]

[tex]\implies \sf m \angle B=70.03913...^{\circ}[/tex]

Therefore, m∠B = 70.0° (nearest tenth)
