Jacob mixes ⅓ cup of yellow paint for every ⅕ cup of blue paint to make green paint. How many cups of yellow paint are needed fo

Nana76 [90]

Answer:

$\frac{5}{3}$ cups

Step-by-step explanation:

Jacob mixes $\frac{1}{3}$ cup of yellow paint for every $\frac{1}{5}$ cup of blue paint to make green paint.

The ratio of yellow paint to blue paint = $\frac{1}{3} : \frac{1}{5}$

= 5:3

$\frac{1}{5}$ cup of blue paint = $\frac{1}{3}$ cup of yellow paint

1 cup of blue paint = $\frac{1}{3}$ ÷ $\frac{1}{5}$ cup of yellow paint

⇒ $\frac{1}{3}$ ÷ $\frac{1}{5}$

⇒ $\frac{5}{3}$

Hence, For 1 cup of blue paint needed $\frac{5}{3}$ cups of yellow paint.

Use the point and the slope to graph each line. Write the equation of the line. The line passes through point (2,-2) and is para

elixir [45]

Answer:

y= -x

Step-by-step explanation:

<u>slope- intercept form</u>

y= mx +c, where m is the slope and c is the y-intercept.

Given that the slope is -1, m= -1.

Substitute m= -1 into the equation:

y= -x +c

To find the value of c, substitute a pair of coordinates into the equation.

When x= 2, y= -2,

-2= -2 +c

c= -2 +2

c= 0

Thus, the equation of the line is y= -x.

Answer:

$\frac{9^{5}}{3}$

Step-by-step explanation:

$\frac{9^{2}}{3} * \frac{9^{4}}{2} = \frac{9^{6}}{6}\\\\\frac{\frac{9^{6}}{6}}{\frac{9^{1}}{2}} \\\\\frac{2*9^{6}}{6*9^{1}}\\\\\frac{9^{5}}{3}$

$\frac{9^{5}}{3} = 19,683$

Y varies directly with x and y=8 when x=-5

ale4655 [162]

Answer:

Y=K×X...... equation

When,Y=8 and X=-5

To find the constant (K)

we substitute for K in the equation

8=K×-5

8=-5K divide both sides by -5

8÷-5=-5K÷-5

K=-1.6
