One month Miguel rented 12 movies and 2 video games for a total of $41. The next month he rented 3 movies and 5 video games for

inn [45]

Step-by-step explanation:

U should use the system of 2 equations.

Let x be the rental cost of a movie and let y be that of video games.

{12x + 2y= 41} eq1

{3x + 5y= 35}eq2 note: eq means equation

The answer is

X=2.5 Y=5.5

So, the rental cost for each movie is 2.5$

and for each video game is 5.5$

30 POINTS AVAILABLE

kherson [118]

Answer:

$\large\boxed{(x-2)^2+(y-1)^2=34}$

Step-by-step explanation:

The equation of a circle in standard form:

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

(h, k) - center

r - radius

We have the endpoints of the diameter: (-1, 6) and (5, -4).

Midpoint of diameter is a center of a circle.

The formula of a midpoint:

$\left(\dfrac{x_1+x_2}{2};\ \dfrac{y_1+y_2}{2}\right)$

Substitute:

$h=\dfrac{-1+5}{2}=\dfrac{4}{2}=2\\\\k=\dfrac{6+(-4)}{2}=\dfrac{2}{2}=1$

The center is in (2, 1).

The radius length is equal to the distance between the center of the circle and the endpoint of the diameter.

The formula of a distance between two points:

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

Substitute the coordinates of the points (2, 1) and (5, -4):

$r=\sqrt{(5-2)^2+(-4-1)^2}=\sqrt{3^2+(-5)^2}=\sqrt{9+25}=\sqrt{34}$

Finally we have:

$(x-2)^2+(y-1)^2=(\sqrt{34})^2$

It took Shane 2 hours to drive 120 miles. If she continues at this rate, how far will she travel in 4 hours and 30 minutes?

vodomira [7]

Answer:

270 miles

Step-by-step explanation:

If she drove 120 miles in 2 hours, that means she drives at 60 miles per hour. 4 hours and 30 minutes can be seen as 4.5, since 30 minutes is half an hour. So then you multiply 60 by 4.5 and get 270.

Louisa drew a polygon with six sides of equal length. If the perimeter of Louisa's polygon is 95.4 centimeters, how long is each

Agata [3.3K]

Answer:

15.9 centimeters

Step-by-step explanation:

the information we have is:

Perimeter: $P=95.4cm$

Number of sides of the polygon: $n=6$

since each side has equal length, we can use the following equation to find the measure of one side of the polygon, the equation for perimeter:

$P=nl$

where n is the number of sides and $l$ is the length of each side.

So we clear for $l$ and we get:

$l=\frac{P}{n}$

and subtituting the known values:

$l=\frac{95.4cm}{6}\\ l=15.9cm$

each side is 15.6 centimeters long
