Answer:

The circumcenter of a triangle is a point that is equidistant from all three vertices. The circumscribed circle is a circle whose center is the circumcenter and whose circumference passes through all three vertices.

Step-by-step explanation:

We can conclude that the circumcenter of a triangle is equidistant from the three vertices of the triangle.

The circumcenter of a triangle can be said to be a point where all three perpendicular bisectors of the sides of the triangle intersect. At this point, all three vertices of the triangle are equidistant.

This means that, each vertices are far from the circumcenter at equal distance.

Therefore, we can conclude that the circumcenter of a triangle is equidistant from the three vertices of the triangle.

9:2 = 18:4

9x2=18

2x2=4

Thus, this answer is true.

22, 24, 26

Step-by-step explanation:

2n - 2 + 2n + 2n + 2 = 72

6n = 72

n = 72/6

n = 12

∴ so three consecutive even integers whose sum is 72 :

2n - 2

= 2(12) - 2

= 24 - 2

= 22

2n

= 2(12)

= 24

2n + 2

= 2(12) + 2

= 24 + 2

= 26

verification

22 + 24 + 26

= 46 + 26

= 72 ✓✓

Answer:

The equation is

[tex]f(x) = - \frac{2}{30} x + 2[/tex]

Step-by-step explanation:

since the function is

[tex]f(x) = - \frac{2}{30} x + 2[/tex]

The y-intercept is 2 and the x-intercept is 30.

since the treadmill is counting down the slope of the function would be negative. she set the treadmill for 2 minute walk so at 0 minutes she has 2 minutes left. as the treadmill counts down at the 30-minute mark she will have zero minutes left.

Answer:

ninety liters

Step-by-step explanation:

Ninety liters of the 50% acid solution have to be mixed with 90 liters of the 30% solution to yield 180 liters of 40% solution.

Answer: 3.5 years

Step-by-step explanation:  Let A be the salaries earned from company A for x years and B for company B for the same years.

A = 31000 + n*3000

B = 38000 + n*1000

To find the case where A = b, set them to each other and solve for n, the number of years.

31000 + n*3000 = 38000 + n*1000

2000n = 7000

n = (7000/2000) = 3.5 years.

Answer:

Y= - x - 6

Step-by-step explanation:

Answer:

The slope is y = x

Step-by-step explanation:

You can find the slope by using the rise over run method with two points.Let's take (1,1) and (2,2). From the first point to the second point, (1,1) goes up one unit and to the right one unit.So the rise over run is 1/1, or 1, which means the slope is 1.

Answer:

m = 1x

Step-by-step explanation:

This is the easiest slope you'll ever have to calculate - if you even need to as it's self explanatory looking at it! Slope = rise/run, thus slope = 1/1 = 1.

Answer:

Step-by-step explanation:

Example: (1 2/3) (2 3/5)

Turn to improper fractions

1 2/3= 5/3   2 3/5= 13/5

5/3 x 13/5=?

5x13= 65

3x5= 15

Simplify/divide: 65/15 = 4 1/3

Another example. (2 5/6)(3)

Improper fraction:  2 5/6= 17/6

Turn Whole number to fraction: 3= 3/1

17/6 x 3/1

17x3= 51

6x1= 6
