Answer:

Step-by-step explanation:

Let s and e represent the grams of 6% and 8% solution, respectively. The given relations can be described by ...

  s + e = 600 . . . . . you have 600 grams of mixture

  0.06s +0.08e = 0.074(600) . . . . grams of alcohol in the mixture

__

The first equation can give an expression for s that substitutes nicely into the second equation:

  s = 600 -e

  0.06(600 -e) +0.08e = 0.074(600) . . . . substitute for s

  0.02e = 0.014(600) . . . . . . subtract 0.06(600)

  e = 420 . . . . . . . divide by 0.02

  s = 600 -420 = 180

You mixed 180 grams of 6% solution with 420 grams of 8% solution.

Answer: 180 grams of 6% solution with 420 grams of 8% solution.

Step-by-step explanation:

Let x and y be the weight (in grams) of 6% and 8% alcohol solution. Since the total weight is 600 grams, therefore,

[tex]$$\Rightarrow x+y=600 \ldots \text { (1) }[/tex]

Using the statement given, we can write the following equation:

[tex]\Rightarrow 6 x+8 y=(7.4)(600)\\ \Rightarrow 6 x+8 y=4440 \text {... (2) }[/tex]

Substitute the value of y from equation (1) into equation (2), we'll get:

[tex]\begin{gathered}\Rightarrow 6 x+8(600-x)=4440 \\\Rightarrow 6 x+4800-8 x=4440 \\\Rightarrow 2 x=360 \\\Rightarrow x=180\end{gathered}[/tex]

Therefore,

[tex]\Rightarrow y=600-180=420[/tex]

Therefore, you mixed 180 grams of 6% solution with 420 grams of 8% solution.

Answer:

  (a, b, c) = (0, -4, 4)

Step-by-step explanation:

Any of a variety of calculators, spreadsheets, or web sites can solve these equations for you. A calculator result is attached. It shows the solution to be ...

  (a, b, c) = (0, -4, 4)

__

If you'd like to solve the system by hand, here's one way:

Add the three equations together:

  (2a +b +c) +(2b +c +a) +(2c +a +b) = (0) +(-4) +(4)

  4a +4b +4c = 0 . . . . simplify

  a +b +c = 0 . . . . . divide by 4

Substitute this into each of the other equations:

  a +(a +b +c) = 0   ⇒   a +0 = 0   ⇒   a = 0

  b +(a +b +c) = -4   ⇒   b +0 = -4   ⇒   b = -4

  c +(a +b +c) = 4   ⇒   c +0 = 4   ⇒   c = 4

Answer:

4/3

Step-by-step explanation:

We can use the slope formula to find the slope

    = ( 6-10)/(2-5)

   = -4/-3

   = 4/3

Let's see

Answer:

[tex]\sf length=\dfrac{4n}{m}[/tex]

Step-by-step explanation:

Area of a rectangle = width × length

Given:

Substituting the given expressions into the equation:

[tex]\sf \implies 12mn^2=3m^2n \times length[/tex]

[tex]\sf \implies length=\dfrac{12mn^2}{3m^2n}[/tex]

Factor 12 to 3 · 4:

[tex]\sf \implies length=\dfrac{3 \cdot 4mn^2}{3m^2n}[/tex]

Cancel the common factor of 3:

[tex]\sf \implies length=\dfrac{4mn^2}{m^2n}[/tex]

Simplify [tex]\sf \dfrac{n^2}{n}=n[/tex] :

[tex]\sf \implies length=\dfrac{4mn}{m^2}[/tex]

Simplify [tex]\sf \dfrac{m}{m^2}=\dfrac{1}{m}[/tex] :

[tex]\sf \implies length=\dfrac{4n}{m}[/tex]

37.5 percent

Step-by-step explanation:

Finding percent is simple. You want to find percent of the price drop so you subtract 50 from 80 and get 30. Once you get 30 you divide by 80 (your original price). Once you do this you will get 0.375. Multiply this by 100 to get your percent.

Answer:

D)  I and IV

Step-by-step explanation:

The variable along the x-axis is the independent variable.

The variable along the y-axis is the dependent variable.

It would be fair to determine that the time spent reviewing a writing assignment is dependent upon the number of spelling mistakes, as the more mistakes an assignment has, the longer it should take to review, however we cannot say this for certain, therefore we cannot assign the dependent and independent variables.

If the scatter plot shows a negative linear relationship, then as the x-values increase, the y-values decrease.

Statements I and IV suggest a negative linear relationship only, depending on which variable is dependent and independent.
(FYI Statements II and III describe positive linear relationships)

Statement I

x-axis (independent variable) = number of spelling mistakes

y-axis (dependent variable) = review time

Statement IV

x-axis (independent variable) = review time

y-axis (dependent variable) = number of spelling mistakes

Therefore, as we cannot be sure which is the dependent variable and which is the independent variable, the solution is D.

[tex]y=5x-18[/tex]

Step-by-step explanation:

Given the following question:

Point A = (4, 2) = (x, y)
Slope = 5

To find the answer we are going to have to use the formula for slope intercept, substitute the values, then solve for the variable b to have our answer.

[tex]y=mx+b[/tex]
[tex]y=2[/tex]
[tex]m=5[/tex]
[tex]x=4[/tex]
[tex]2=5(4)+b[/tex]
[tex]5\times4=20[/tex]
[tex]2=20+b[/tex]
[tex]20-20=0[/tex]
[tex]2-20=-18[/tex]
[tex]-18=b[/tex]
[tex]b=-18[/tex]
[tex]y=5x-18[/tex]

Your answer is "y = 5x - 18."

Answers:

Reason:

Refer the diagram below to see how rectangular cross sections are possible. The cross sections are marked in red.

For the rectangular prism, we could have a vertical or horizontal plane. For the cylinder, only a vertical cross section is possible. On the flip side, a rectangular pyramid can only have horizontal rectangular cross sections (which are similar to the base).

Problem 2

Answer: Approximately 73,280.62908 square feet

Explanation:

Calculate the area of the trapezoid. Ignore the small triangle for now.

A = h*(b1+b2)/2

A = 354*(266+158)/2

A = 75,048

Now calculate the area of the triangle we ignored earlier

Before we do this, we'll need to use the pythagorean theorem to find the missing horizontal piece

a^2 + b^2 = c^2

b = sqrt(c^2 - a^2)

b = sqrt(97^2 - 40^2)

b = 88.368546 which is approximate.

Now we can find the area of the small triangle

Area = base*height/2 = 88.368546*40/2 = 1,767.37092

This is to be subtracted from the area of the trapezoid we found earlier.

75,048 - 1,767.37092 = 73,280.62908

Round the result however you need to.

The dilations will give the relations:

C'D = (3/4)CD and A'B' = (1/2)AB

And a sketch of the graph can be seen at the end.

First, we want to dilate point C using D as the center of dilation with a scale factor = 3/4.

This only means that we will have the new point C', such that:

C'D = (3/4)*CD

Where CD is the distance between points C and D

b) Similarly, we will dilate the whole segment AB into the segment A'B', such that:

A'B' = (1/2)AB.

It is hard to give the exact graph when we don't know the coordinates of the points, but the graph should look something like the one you can see below.
