Allushta [10]

Answer:

11 bottles

Step-by-step explanation:

make a proportion because if you're using the same rate proportions can show that it's equal

$\frac{7}{90} = \frac{x}{140}$

cross multiply

$7 *140$ $= 980$

divide the answer by 90 to find x

$980/90= 10.8$

round to 11 because you can't have 10.8 bottles

Select the correct answer. Which point lies on the circle represented by the equation (x + 7)2 + (y − 10)2 = 132? A. (5,12) B. (

Feliz [49]

Answer:

B. (-7,-3)

Step-by-step explanation:

Given the circle: $(x + 7)^2 + (y - 10)^2 = 13^2$

The point (x,y) which lie on the circle are the coordinate which satisfies the given equation of the circle.

We now consider the given options.

Option A (5,12)

When x=5, y=12

$(5 + 7)^2 + (12 - 10)^2 =12^2+2^2=148\neq 169= 13^2$

Option B (-7,-3)

When x=-7, y=-3

$(-7 + 7)^2 + (-3 - 10)^2 =0^2+(-13)^2= 169=13^2$

Option C (-6,-10)

When x=-6, y=-10

$(-6 + 7)^2 + (-10 - 10)^2 =1^2+(-20)^2=401\neq 169= 13^2$

Option D (6,23)

When x=6, y=23

$(6 + 7)^2 + (23 - 10)^2 =13^2+13^2=338\neq 169= 13^2$

We can see that only (-7,-3) satisfies the equation of the circle. Thus it is the point which lies on the circle.

The correct option is B.
