Paris Nights sweater: $60

Markup: 35% of $60

35/100=x/60

Cross multiply

2100 divide by 100 is 21

$60 + $21 = $81

The answer is $81

Please help don’t get it

Romashka-Z-Leto [24]

Answer:

Step-by-step explanation:

One complete turn is 1 perimeter (aka circumference).

We have to find the length it turned, hence, its circumference.

The formula for circumference (C) of a circle is:

$C=2\pi r$

Where r is the radius

The radius is HALF of diameter. Given diameter is 250, the radius is:

r = 250/2 = 125 feet

Now, substituting in formula we have:

$C=2\pi r\\C=2\pi (125)\\C=250\pi\\C=785.4$

So, it turned 785.4 feet with 1 rotation.

The correct answer is A

addison and kelsey are running on a path modeled by x^2+y^2-10x-18y-378=0, where the distance is in meters. what is the maximum

bulgar [2K]

The maximum distance is the diameter of the circle, which is of 44 units.

The equation of a circle of radius r and center $(x_0,y_0)$ is given by:

$(x - x_0)^2 + (y - y_0)^2 = r^2$

The diameter is twice the radius, and is the maximum distance between two points inside a circle.

In this problem, the circular path is modeled by:

$x^2 + y^2 - 10x - 18y - 378 = 0$

We complete the squares to place it in the standard format, thus:

$x^2 - 10x + y^2 - 18y = 378$

$(x - 5)^2 + (y - 9)^2 = 378 + 25 + 81$

$(x - 5)^2 + (y - 9)^2 = 484$

Thus, the radius is:

$r^2 = 484 \rightarrow r = \sqrt{484} = 22$

Then, the diameter is:

$d = 2r = 2(22) = 44$

The maximum distance is the diameter of the circle, which is of 44 units.
