$\bf \begin{array}{ccll}
\stackrel{mL}{hardener}&\stackrel{resin}{container}\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
50&1\\
x&19
\end{array}\implies \cfrac{50}{x}=\cfrac{1}{19}\implies \cfrac{50\cdot 19}{1}=x\implies \stackrel{mL}{950}=x
\\\\\\
\textit{now, there are 1000 mL in 1 liter, so }950~\underline{mL}\cdot \cfrac{L}{1000~\underline{mL}}
\\\\\\
\cfrac{950}{1000}L\implies 0.95~L$

Which ordered pair minimizes the objective function C = 60x + 85y?. (0, 160). (55, 70). (80, 50). (170, 0)

dangina [55]

Step-by-step explanation:

The given objective function is $C = 60x + 85y$

To check that which ordered pair is minimizing the objective function-we will substitute all the ordered pair one by one in the given function and we will calculate the value of C. The ordered pair which will give the minimum value will be the answer.

For (0, 160)

$C=60\times 0+85\times 160=13600$

For (55, 70)

$C=60\times 55+85\times 70=9250$

For (80, 50)

$C=60\times 80+85\times 50=9050$

For (80, 50)

$C=60\times 170+85\times 0=10200$

Hence the ordered pair which minimizes the objective function is (80, 50)

Given: LMNB is a square, LM = 20cm, P∈ LM , K ∈ PN , PK = 1 5 PN, LP = 4 cm Find: Area of LPKB

Bad White [126]

Answer:

80 cm²

Step-by-step explanation:

Trapezoid LPKB has area ...

A = (1/2)(b1 +b2)h = (1/2)(4 +20)(20) = 240 . . . . cm²

Triangle BPN has area ...

A = (1/2)bh = (1/2)(20)(20) = 200 . . . . cm²

Triangle BKN has a height that is 4/5 the height of triangle BPN, so will have 4/5 the area:

ΔBKN = (4/5)(200 cm²) = 160 cm²

The area of quadrilateral LPKB is that of trapezoid LPNB less the area of triangle BKN, so is ...

240 cm² - 160 cm² = 80 cm²

If you were to make a scatter plot of data, you would be able to determine the line of best fit. Using the regression equation y

VMariaS [17]

Answer:

Option B. is correct

Step-by-step explanation:

Given: The regression equation is y = 1.73 x + 0.39

To find: number of representatives for Oregon, which has a population of about 3.3 million

Solution:

The regression equation determined the specific relationship between a dependent variable and one or more independent variables.

To find number of representatives for Oregon, which has a population of about 3.3 million, put $x=3.3$ in the regression equation is y = 1.73 x + 0.39

$y = 1.73 x + 0.39\\y = 1.73 (3.3) + 0.39\\=5.709+0.39\\=6.099\\\approx 6$

So, 6 representatives for Oregon has a population of about 3.3 million

Option B. is correct
