Answer:

Option B is right

Step-by-step explanation:

We have in a triangle there are some properties inherent.

One is the perpendicular bisectors of all sides are concurrent.

These three concur at a point called the circumcentre of the triangle.

When we draw perpendicular bisector for a side AB, we get that all points on the perpendicular bisector are equidistance from A and B.

When we take the point of intersection of perpendicular bisector of AB and BC, we have the intersecting point S(say) is equidistant from A and B and also from B and C

In short this is equidistant from all 3 vertices and hence is centre of circumcicle of triangle ABC

The yearly cost y for driving a certain car is $7,800 for 10,000 miles
Licemer1 [7]

Answer:

y = 0.36x + 4200.00

15100.00 miles.

Step-by-step explanation:

If the yearly cost for driving x miles is given by y dollars then the two ordered pairs to find the linear relation between x and y are (10000,7800) and (20000,11400).

So, the equation will be

\frac{y - 11400}{11400 - 7800} = \frac{x - 20000}{20000 - 10000}

⇒ \frac{y - 11400}{3600} = \frac{x - 20000}{10000}

⇒ y - 11400 = \frac{9}{25}(x - 20000)

⇒ y - 11400 = \frac{9}{25}x - 7200

⇒ y = \frac{9}{25}x + 4200

⇒ y = 0.36x + 4200.00 ........... (1) (Answer)

Now, for y = $9636.00, from equation (1),

9636 = 0.36x + 4200

⇒ 0.36x = 5436

⇒ x = 15100.00 miles. (Answer)

Jamie purchased a DVD that was on sale for 15% off. The sales tax in her county is 5%. Let y represent the original price of the
FromTheMoon [43]
Since y is the original cost, let z represent the final cost. So, we set up the expression, (0.12y + y) - 0.03y = z. That shows first the sale, then the tax. From there, we simplify to get 1.12y - 0.03y = z, then simplify it more to get 1.09y = z. We take away the z, and get that the cost, which is 1.09, or 109%, or y (1.09y).
