A container of orange juice has a pH of 3.3. Find the concentration of hydronium ions in the milk.
pH = -log[H30+]
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.
What is pH value?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.

Product of 12 => 12x
is greater than => [tex]\geq[/tex]
24
so 12x [tex]\geq[/tex] 24
Answer:
c. 12x > 24
Step-by-step explanation:
Only one choice has the "greater than" symbol. It is C.
A number is the variable x.
The product of 12 and a number is 12 × x which is written simply as 12x.
12x is greater than 24.
The symbol for "greater than" is >.
Answer: c. 12x > 24
Graham and hunter are circus performers. a cable lifts graham into the air at a constant speed of 1.5 ft/s. when graham’s arms are 18 ft above the ground, hunter, who is standing directly underneath graham, throws graham a ball as the cable continues to lift him higher. hunter throws the ball from a position 5 ft above the ground with an initial velocity of 24 ft/s. which system of equations can be used to model this situation? startlayout enlarged left-brace 1st row h = 18 1.5 t 2nd row h = 5 24 t minus 16 t squared endlayout startlayout enlarged left-brace 1st row h = 18 1.5 t 2nd row h = 5 24 t 16 t squared endlayout startlayout enlarged left-brace 1st row h = 18 1.5 t 2nd row h = 5 24 t endlayout startlayout enlarged left-brace 1st row h = 18 1.5 t minus 16 t squared 2nd row h = 5 24 t 16 t squared endlayout
Therefore, the system of equations that can be used to model this situation is h= 5 + 24t -16t^2.
What is the system of equation about?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.

The shopkeeper agrees to give him a total discount of $70, but charges $9 for every pen. what is the maximum number of pens he can buy now?
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.

evaluate sin 315 without a calculator
Answer:
-0.7071.
Step-by-step explanation:
The value of function sin 315 is -1/2.
What is Trigonometry?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.

Find m∠B to the nearest tenth.
Answer:
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:
a = 13c = 19A = 40°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)
mean: _.5
Median: 5._
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
