Answer:

See below

Step-by-step explanation:

In simple comparisons like this, we can find the simplest unit rate.

since we want cocoa compared to sugar used, we can find <em>amount of cocoa used PER tablespoon of sugar</em>.

Basically unit rate of sugar.

We have

8 tbsp Cocoa : 2 tbsp sugar   [tbsp = tablespoons]

divide both side by 2, we have

8/2 : 2/2

4 : 1

Thus,

4 tbsp Cocoa : 1 tbsp Sugar

Hence, for every tablespoon of sugar Leah uses, she uses 4 tablespoons of Cocoa to make hot chocolate.

Identify the equation for the circle with center (3, 7) that contains the point (9, 11).
Finger [1]

Answer:

(x-3)^2+(y-7)^2=2\sqrt{13}

Step-by-step explanation:

The equation of a circle:

(x-h)^2+(y-k)^2=r^2

(h, k) - center

r - radius

We have the center (4, -3) and the point on the circle (9, -3).

The length of radius is equal to the distance between a center and an any point on a circle.

The formula of a distance between two points:

r=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Susbtitute:

r=\sqrt{(9-3)^2+(11-7)^2}\\\\=\sqrt{6^2+4^2}\\\\=\sqrt{52}\\\\=2\sqrt{13}

The center (3, 7) → h = 3, k = 7.

Finally we have:

(x-3)^2+(y-7)^2=2\sqrt{13}
