Answer:

D

Step-by-step explanation:

The required explanatory variable is concentration of active ingredients. Option D is correct.

Given that,
From the paragraph, "Medical researchers studying a medication in male and female patients 20 to 29 years old noticed that, up to a certain amount, a larger concentration of an active ingredient lead to greater levels of symptom relief." it is to be determined which is an explanatory variable.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
A) age of patient = Not explanatory

B) gender of the patient = Not explanatory

C) amount of symptom relief = Not explanatory

D) concentration of active ingredient =  Explanatory

Thus, the required explanatory variable is the concentration of active ingredients. Option D is correct.

the difference is that -50  is -50 celsius from 0 hope this helps at all!?

Step-by-step explanation:

Answer:

50

Step-by-step explanation:

0 is larger then -50 and you want the difference so minus them

0-(-50) now when 2 negative signs meet like this they turn to addition

0+50 which is 50

their difference is 50

im pretty sure it this because it would make 180 degrees ;-;

Answer:

20 degrees

Step-by-step explanation:

angles on a straight line/ straight line angles/ supplementary angles = 180 degrees

angle 1 + angle 2 = 180 degrees

160 + angle 2 = 180

angle 2 = 180 = 160

angle 2 = 20 degrees

Answer:

2 inches

Step-by-step explanation:

Given that:

Dimensions of rectangular board = 12 inches by 16 inches

Area of uniform border around the rectangular board = 128 square inches

To find:

Width of the border = ?

Solution:

Let the width of the uniform border = [tex]x[/tex] inches

Now, there are two rectangular shapes after the addition of border.

One rectangle with the border, one without the board.

Area of border can be found by subtracting the area of board from the area of rectangle with the board.

Dimensions of the rectangle with the border = (12+2[tex]x[/tex]) inches by (16+2[tex]x[/tex]) inches

Area of rectangle = Length [tex]\times[/tex] Width

So, area of border = ((12+2[tex]x[/tex]) [tex]\times[/tex] (16+2[tex]x[/tex])) - 16 [tex]\times[/tex] 12 = 128 square inches

[tex]\Rightarrow 4x^2+56x+192-192=128\\\Rightarrow 4x^2+56x-128=0\\\Rightarrow x^2+14x-32=0\\\Rightarrow (x+16)(x-2)=0\\\Rightarrow x = 2, -16[/tex]

Width can not be negative, so possible value of width = 2 inches

Complete Question

Bonnie is making a dipping sauce. She mixes 150 milliliters of soy sauce with 100 milliliters of vinegar. How much soy sauce does Bonnie mix with every 1 milliliter of vinegar?

Answer:

1.5 mm soy sauce

Step-by-step explanation:

Bonnie is making a dipping sauce. She mixes 150 milliliters of soy sauce with 100 milliliters of vinegar. How much soy sauce does Bonnie mix with every 1 milliliter of vinegar?

Hence:

100 mm vinegar = 150mm soy sauce

1 mm vinegar = x

Cross Multiply

100 × x = 150 × 1

x = 150 × 1/100

x = 1.5 mm soy sauce

Hence, Bonnie mixes with every 1 milliliter of vinegarwoth 1.5 mm soy sauce

t = -1/8.

Step-by-step explanation:

t / 5/12 = -3/10          Invert the 5/12 and multiply:

12t / 5 = -3/10

Cross multiply:

12t * 10 = 5 * -3

120t = -15

t = -15/120 = -1/8.

Answer:

m<L = [tex]33.9^{o}[/tex]

Step-by-step explanation:

Triangle JKL is an isosceles triangle, given that <J ≅ <L. An isosceles triangle has two of its angles and sides to be equal.

The exterior angle formed = [tex]67.8^{0}[/tex]

But,

<J + <L = [tex]67.8^{0}[/tex] (the sum of two opposite interior angles is equal to the exterior angle)

Let <J ≅ <L be represented by a, so that;

a + a =  [tex]67.8^{0}[/tex]

2a = [tex]67.8^{0}[/tex]

a = [tex]\frac{67.8^{o} }{2}[/tex]

  = [tex]33.9^{o}[/tex]

The measure of <L is m<L = [tex]33.9^{o}[/tex] (m<L =

Thus,

m<J ≅ m<L = [tex]33.9^{o}[/tex]
