Sally used all of the paint shown to make a certain tint of orange paint. How many pints of red paint should be mixed with 24 pi

ruslelena [56]

Answer:

18 pints

Step-by-step explanation:

As we can see, three pint of yellow paint was mixed with four pint of red paint. Let x represent the number of yellow paint and let y represent the number of red paint. Therefore, the ratio of the two paints is:

x/y = 3/4

x = (3/4)y

To calculate the number of red paints (x) that is needed to be mixed with 24 pints of yellow paint, we use the equation and substitute y as 24. Hence:

x = (3/4)y

x = (3/4) * 24

x = 18 pints

Write an equation in slope intercept form of a line that passes through (-2, 1) and (4,2).

fenix001 [56]

Answer:

$\displaystyle y = \frac{1}{6}x + 1\frac{1}{3}$

Step-by-step explanation:

First, find the <em>rate of change</em> [<em>slope</em>]:

$\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-1 + 2}{2 + 4} = \frac{1}{6}$

Now plug these coordinates into the Slope-Intercept Formula. It does not matter which ordered pair you choose:

2 = ⅙[4] + b

⅔

$\displaystyle 1\frac{1}{3} = b \\ \\ y = \frac{1}{6}x + 1\frac{1}{3}$

_______________________________________________

1 = ⅙[−2] + b

−⅓

$\displaystyle 1\frac{1}{3} = b \\ \\ y = \frac{1}{6}x + 1\frac{1}{3}$

** You see? I told you it did not matter which ordered pair you choose because you will ALWAYS get the exact same result.

I am joyous to assist you anytime.

tigry1 [53]

Answer:

600kW

Step-by-step explanation:

Referring to the fact that 10m/s of wind is 500kW so divide 500 by 10.

500/10=50

So there is 50 kW is 1m/s of wind. Now multiply 12 by 50

12x50=600

So for 12m/s of wind there is 600kW
