To visit her grandmother, Melek takes a motorcycle 3.8 kilometers and a horse 3.32 kilometers. In total, the journey takes 50.54

lbvjy [14]

Answer:

Therefore, total number of Kilometers Melek covered =3.3 + 3.32 = 6.62 kilometers.

Step-by-step explanation:

Distance covered by motorcycle = 3.8 kilometers.

Distance covered by horse = 3.32 kilometers.

Total time taken to complete the journey = 50.54 minutes.

We need to find the total number of kilometers Melek took the journey.

We are given time. But we need not to do anything with given time.

We just need to add the journey took by motorcycle and journey took by horse.

A string of decorative lights is 28 feet long. The first light on the string is 16 inches from the plug. If the lights on the st

lilavasa [31]

Well if there is 28 feet, that would be (12x28) 336 inches, and 16 inches between the plug and the first light, there would be only 320 inches left for lights. therefore, if there are 4 inches between each light, we divide 320 by 4. the answer we get is 80. there are 80 lights.

Write an equation of the circle with center , −45 and radius 6 .

IceJOKER [234]

The general equation for a circle, $x^2+y^2=1$ , falls out of the Pythagorean Theorem, which states that the square of the hypotenuse of a right triangle is always equal to the sum of the squares of its legs (you might have seen this fact written like $a^2+b^2=c^2$ , where a and b are the legs of a right triangle and c is its hypotenuse. When we fix c in place and let a and b vary (in a sense, at least; their values are still dependent on c), the shape swept out by all of those possible triangles is a circle - a shape defined by having all of its points equidistant from some center.

How do we modify this equation to shift the circle and change its radius, then? Well, if we want to change the radius, we simply have to change the hypotenuse of the triangle that's sweeping out the circle in the first place. The default for a circle is 1, but we're looking for a radius of 6, so our equation, in line with Pythagorus's, would look like $x^2+y^2=6^2$ , or $x^{2} +y^2=36$ .

Shifting the center of the circle is a bit of a longer story, but - at first counterintuitively - you can move a circle's center to the point (a,b) by altering the x and y portions of the equation to read:

$(x-a)^2+(y-b)^2$
