The percentage chance of a solution, or essentially its mass/volume percent concentration, with 150 g active ingredient in a total of 1000 mL of solution is 15%.
Explanation:The student is asking how to calculate the mass/volume percent concentration of a solution with a given amount of active ingredient and total solution volume. To find the percentage concentration, we use the mass of the active ingredient and the total volume of the solution. In this case, it is a 150 g active ingredient in 1000 mL of solution, assumming the solution's density is 1.0 g/mL which is typical for dilute aqueous solutions.
In order to calculate the mass/volume percent (m/v %), we use the formula:
% m/v = (Mass of solute in grams × 100) ÷ Volume of solution in mL
Plugging in the values we get:
% m/v = (150 g × 100) ÷ 1000 mL = 15%
Therefore, the solution has a mass/volume percent concentration of 15%.
Final answer:
The percentage chance of the solution with 150g of active ingredient in a total of 1000mL is 15%.
Explanation:
To calculate the percentage chance of a solution containing 150 g active ingredient in a total of 1000 mL of solution, we use the concept of mass/volume percentage. This concept is often used in chemistry to express the concentration of a solute in a solution.
Assuming the density of the solution is 1.0 g/mL, which is common for dilute aqueous solutions, the total mass of the solution will also be 1000 g.
The mass/volume percentage is hence calculated as:
% m/v = (mass of solute in grams) / (volume of solution in milliliters) x 100%
In this case, it's:
% m/v = (150 g)/(1000 mL) x 100% = 15%
So, the solution has a 15% mass/volume percentage of active ingredient.
Describe the transformation that maps the pre image A to the image A'
A) translated 9 units up and then reflected across the y-axis
B) translated 6 units to the right then translated 9 units up
C) translated 9 units to the right then translated 6 units up
D) translated 6 units to the right and then reflected across the x-axis
Answer:
B) translated 6 units to the right then translated 9 units up
Step-by-step explanation:
Just use the graph to follow each translation until you get thee right answer, or you can count how many spaces are from the pre-image to the image. Just make sure to always use the same point.
The transformation from figure A to figure A' are:
Translating 6 units to the right.
Translated 9 units up.
Option B is the correct answer.
What is translation?It is the movement of the shape in the left, right, up, and down directions.
The translated shape will have the same shape and shape.
There is a positive value when translated to the right and up.
There is a negative value when translated to the left and down.
We have,
We will take two coordinates from the figure.
Figure A has the coordinates:
(-5, -2) and (-4, -2)
And,
Figure A' has the coordinates:
(1, 7) and (2, 7)
Now,
Translating 6 units to the right.
(-5, -2) = (-5 + 6, -2) = (1, -2)
And,
(-4, -2) = (-4 + 6, -2) = (2, -2) _____(1)
Again,
Translated 9 units up.
(1, -2) = (1, -2 + 9) = (1, 7)
And,
(2, -2) = (2, -2 + 9) = (2, 7) ______(2)
From (1) and (2) we see that,
Figure A to Figure A'.
Translating 6 units to the right.
Translated 9 units up.
Thus,
The transformation from figure A to figure A' are:
Translating 6 units to the right.
Translated 9 units up.

Describe in words how to obtain the graph of f(t) = sin(5t + 20) − 7 from the graph of y = sin(5t).
Answer: f(t) is shifted 20 units to the left and 7 units down
Step-by-step explanation:
The general form of a sin function is: y = A sin (Bx - C) + D
A is the vertical stretch (amplitude)B is the horizontal compressionC is the horizontal shift (left or right)D is the vertical shift (up or down)y = sin (5t)
f(t) = sin (5t + 20) -7
the C-value is -20 --> shifts 20 units to the leftthe D value is -7 --> shifts 7 units downFind the sum of the first 100
The terms of an arithmetic sequence are generated by adding a fixed term [tex]r[/tex] every time.
So, we start with [tex]a_1=15[/tex], and we continue with [tex]a_2=15+r[/tex], [tex]a_3=15+2r[/tex] and so on.
As you can see, the general rule is [tex]a_n = 15+(n-1)r[/tex]
With this information, we can derive [tex]r[/tex], knowing that
[tex]a_{100} = 307 = 15+99r \iff 99r = 292 \iff r = \dfrac{292}{99}[/tex]
So, the sum of the first 100 terms is
[tex][tex]\displaystyle \sum_{i=0}^{99} 15+i\dfrac{292}{99} = \displaystyle \sum_{i=0}^{99} 15 + \displaystyle \dfrac{292}{99}\sum_{i=0}^{99} i = (15\cdot 99) + \dfrac{292}{99}\dfrac{99\cdot 100}{2} = 1485 + \dfrac{490342}{99}[/tex]

Answer:
"The number c is a zero the polynomial function y=P(x) if and only if x-c is a factor of the polynomial P(x)."
Step-by-step explanation:
We have been given some statements with blank spaces:
"The number c is a _______ of the polynomial function y=P(x) if and only if x-c is a _______ of the polynomial P(x)."
Now we need to fill those blank spaces by suitable words.
We know that if x=5 is some root (zero or solution) of the polynomial function then (x-5) works as factor.
So using that logic, we can fill the blanks spaces as:
"The number c is a zero the polynomial function y=P(x) if and only if x-c is a factor of the polynomial P(x)."
Answer:
I am 86% sure that it is The number c is zero the polynomial function y=P(x) if and only if x-c is a factor of the polynomial P(x)

Two planes left simultaneously from the same airport and headed in the same direction towards another airport 1800 km away. The speed of one of the planes was 100 km/hour slower than the speed of the other plane, and so it arrived at its destination 36 minutes after the faster plane. Find the speeds of both planes.
Answer:
Faster plane --> 600km/hr
Slower Plane --> 500km/hr
Step-by-step explanation:
Use inequality: 1800/r = 1800/(r-100) + 3/5 and solve to get r = 600, so the plane which is r -100 is 500 km/hr.

Select the ordered pair that is a solution to the equation represented by the graph.
I believe it is because it would be he most simplistic answer to be honest because for example 10,8 it is the same as 5,4 so u would put 5,4 because it is simplified so put (2.1,0) as your answer
The ordered pair that is a solution to the equation represented by the graph is (-2.5, 3).
Here's my reasoning:
- The graph intersects the x-axis at (2.1, 0): This means that any point on the x-axis, including (2.1, 0), has a y-value of 0. However, this doesn't guarantee that (2.1, 0) is a solution to the equation itself.
- The graph passes through the point (-2.5, 3): This means that the equation of the graph must yield a y-value of 3 when x = -2.5. Therefore, (-2.5, 3) is a solution to the equation.
The other points are not on the graph itself:
- (0, 0.6) is above the x-axis but not on the graph's line.
- (-1, 1.8) is also above the x-axis but not on the graph's line.
Therefore, the only ordered pair that is a solution to the equation represented by the graph is (-2.5, 3).

Rebecca has a credit line of $6,500. She had a previous balance of $398.64 and made a payment of $250. The total of her purchases is $1,257.99. What is Rebecca's available credit?
Answer:
$5093.37
Step-by-step explanation:
To get Rebecca's available credit we need to take all of her payments and purchases and previous balance.
Previous balance = $398.64
Purchases = $1,257.99
Payment = $250
Credit Line = $6,500
Now first we add together her purchases and previous balance.
398.64 + 1,257.99
This will give us:
$1,656.63 Total deductions.
Now we subtract that to her credit line.
$6500.00 - $1656.63
$4843.37
Now we take her payment and add it to her credit line.
$4843.37 + $250
$5093.37
So Rebecca's available credit is $5093.37.

A plane takes off at an angle of elevation of 15° and travels in a straight line for 3,000 meters. What is the height of the plane above the ground at this instant?
Answer:
776.46 m
Step-by-step explanation:
According to the scenario it is a question of right angle triangle
To find the height of the plane above the ground we will use trigonometry identity.
sinФ = opposite / hypotenusehere Ф = 15°
opposite = height
hypotenuse = 3000m
Plug values in the formula above
sin(15) = height / 3000height = sin(15)(3000)
= 776 .46 m
(make sure your calculator is in degree mode)
Answer:
776.46 m
Step-by-step explanation:
The angle of elevation is 15 degrees which is measured from the horizontal.
The height above the ground is the opposite side of the triangle, the hypotenuse is the 3000 m and the angle of elevation is 15 degrees.
The sine ratio is the one one that ties the relationship;
Therefore;
sin 15 = x/3000
x = sin 15 × 3000
= 776.46 m
