Answer:

24 bricks

Step-by-step explanation:

The equation of the bricks per row can be:

b = 60 - 3r

where r = row and b = bricks.

if r = 12:

$b = 60 - 3 * 12\\b = 60 - 36\\b = 24$

Find an equation of the circle that satisfies the given conditions.

hodyreva [135]

The equation of a circle:
$(x-h)^2+(y-k)^2=r^2$
(h,k) - the coordinates of the centre
r - the radius

The midpoint of the diameter is the centre of a circle.
The coordinates of the midpoint:
$(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$
(x₁,y₁), (x₂,y₂) - the coordinates of endpoints

$P(-1,1) \\
x_1=-1 \\ y_1=1 \\ \\ Q(5,9) \\ x_2=5 \\ y_2=9 \\ \\
\frac{x_1+x_2}{2}=\frac{-1+5}{2}=\frac{4}{2}=2 \\ \frac{y_1+y_2}{2}=\frac{1+9}{2}=\frac{10}{2}=5$

The centre of the circle is (2,5).

The radius is the distance between an endpoint of the diameter and the centre.
The formula for distance:
$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$(-1,1) \\ x_1=-1 \\ y_1=1 \\ \\ (2,5) \\ x_2=2 \\ y_2=5 \\ \\ d=\sqrt{(2-(-1))^2+(5-1)^2}=\sqrt{3^2+4^2}=\sqrt{9+16}=\sqrt{25}=5$

The radius is 5.

$(x-2)^2+(y-5)^2=5^2 \\
\boxed{(x-2)^2+(y-5)^2=25}$

Number of rides marine can go on ?

saul85 [17]

Answer:

Check step by step explanation

Step-by-step explanation:

a) Let x represent the amount of rides she takes, the 6 and 2.5 represent the amount of money required to enter

A(x) = 1.5x + 6

B(x) = 2x + 2.5

b) You can find this by making the 2 equations equal to each other and solving for x

1.5x + 6 = 2x + 2.5

3.5 = .5x

7 = x

7 rides make them equal cost

c) Plug in 5 for each of the equations and find out which one is cheaper

A(5) = 1.5 * 5 + 6

A(5) = $13.50

B(5) = 2 * 5 + 2.5

B(5) = $12.50

Carnival B is cheaper
