A) tomatoes : chicken broth = 9:15 or 3:5
Tomatoes : spinach = 9:9 = 1:1
Spinach : chicken broth = 9:15 = 3:5

b) tomatoes : chicken broth = 4.5:7.5 = still 3:5
Tomatoes to spinach is still 1:1
Spinach : chicken broth 4.5:7.5 still = 3:5

Dividing all quantities by 2 doesn’t change the ratio.

A line has a slope of -1/3 and includes the points (q, 2) and (6, 3). What is the value of q?
elena55 [62]

Answer:

9

Step-by-step explanation:

Given the knowledge that the slope is -1/3 and includes the point (6,3), you can subtract one from the y value and add three to the x value, resulting in (9,2). Q is equal to 9.

Write the standard equation of a circle having endpoints of a diameter at (-1, 6) and (9,-8).
MAXImum [283]

Answer:

r ^{2} = (x-4)^2 + (y+1)^{2}

Given:

endpoints at (-1, 6) and (9, -8)

Solve for:

the standard equation of a circle having endpoints of a diameter at (-1, 6) and (9,-8).

Step-by-step explanation:

d=\sqrt{(x_{2} -x_{1})^2+(y_{2} -y_{1})^2}

d=\sqrt{(9-(-1))^2+(-8-6)^2}

d=\sqrt{10^2+-14^2}

d=\sqrt{100+196}

d=\sqrt{296}

d=2\sqrt{74}

r=\frac{d}{2}

r=\frac{2\sqrt{74} }{2}

r=\sqrt{74}

Center = (\frac{x_{1}+x_{2} }{2} ,\frac{y_{1}+y_{2} }{2})

= (\frac{-1+9}{2}, \frac{6+(-8)}{2} )

=(4, -1)

Center = (4,-1) \\and\\r = \sqrt{74}

Equation:

(\sqrt{74}) ^{2} = (x-4)^2 + (y+1)^{2}

r ^{2} = (x-4)^2 + (y+1)^{2}

*This took forever so I hoped it helped lol*
