the middle of the triangle's circle. It is the intersection of the "perpendicular bisectors," or lines that are perpendicular to the middle of each side.

Triangle ABC's circumcenter is the point at which any two perpendicular bisectors of any two sides of the triangle come together.

The perpendicular bisector of sides B(3,0) and C(3,2) has the equation is y=1.

Because AB's slope is unknown and its midpoint is at 3,1. The slope of the perpendicular bisector is zero. Such a line has the equation y=y1.

Additionally, x=1.5 is the equation for the perpendicular bisector of A(0,0) and B(3,0). The explanation is because AB has a zero slope and a midway of (1.5,0). The slope of the perpendicular bisector will be ill-defined. x=x1 is the equation for such a line.

The expression 17n+11 represents the perimeter of a triangle, which is the sum of the lengths of the three sides of the triangle. Therefore, we can use this expression to determine the length of the third side of the triangle.

Since the perimeter of the triangle is equal to 17n+11, we know that the sum of the lengths of the three sides is equal to 17n+11. We can write this as:

a + b + c = 17n+11

where a, b, and c are the lengths of the three sides of the triangle.

To determine the length of the third side, we need to know the lengths of the other two sides. However, since the question does not provide this information, we cannot determine the length of the third side with certainty. In general, there are many different triangles that could have a perimeter of 17n+11, and the length of the third side could vary depending on the specific lengths of the other two sides.

Without additional information about the lengths of the other two sides, it is not possible to determine the length of the third side of the triangle.

Answer:

a. 10 km

b. 25 km

c. 35 km

Step-by-step explanation:

You are given the rate running = 5 km per 0.5 hr and the rate for biking = 20 km per 0.8 hr. Set up a proportion to get from 0.5 hr to 1 hr multiply by 2, so multiply 5 km by 2 = 10 km. Do the same for biking 0.8 hr to 1 hr is multiplied by 1.25, so multiply 20 by 1.25 = 25 km. Add those two values together for c to get 35 km. See attached image

Eve made 56 free throws for every 30missed throws in her practice

What is ratio?

In mathematics, a ratio is a comparison of two or more numbers that indicates their sizes in relation to each other.

From the question;

The ratio of misses would be: 7:3

If she missed 24 free throws, the new ratio would be: x:24

To do this, we would need to find how many times did 3 go into 24.

3 goes into 24 8 times. We do the same thing to the 7.

We multiply 7x8, which is 56.

The new ratio is: 56:24

Club members spent 13 of the beginning balance to attend their first tournament so, the Chess Club spent $77 on their second tournament.

To calculate the balance of a sum of money, you need to know the initial amount of money and any additions or subtractions that have been made to it.

For example, if you start with $100 and then receive an additional $50, your balance would be $100 + $50 = $150. If you then spend $25, your balance would be $150 - $25 = $125.

To determine how much money the Chess Club spent on their second tournament, we need to first calculate the remaining balance after the first tournament. The Chess Club spent 13 of the beginning balance of $321, so the remaining balance is $321 - $13 = $308.

Next, we need to calculate 25% of the remaining balance. 25% of $308 is (25/100) * $308 = $77.

Thus, the Chess Club spent $77 on their second tournament.

Inequalities are created through the connection of two expressions. It should be noted that the expressions in inequality aren't always equal. Inequalities implies that the expressions are not equal. They are denoted by the symbols ≥  <  >   ≤.

An inequality is created when two or more algebraic expressions are compared using the symbols. They represent mathematical expressions where neither side is equal.

p ≠ q means that p is not equal to q

p < q means that p is less than q

p > q means that p is greater than q

p ≤ q means that p is less than or equal to q

p ≥ q means that p is greater than or equal to q

The lengths of the sides of the rectangular field should be 244.95 m in order to minimize the cost of the fence.

Let the dimensions of a rectangular field be;

Length = l

Width = w

We know that the formula for perimeter of a rectangle is;

P = 2(l + w)

And the formula for area of the rectangle is;

A = lw

⇒ w = A/l

Subtitute w = A/l in the formula of perimeter of rectangle.

P = 2l + 2(A/l)

P = 2L + 2A/l

We differentiate above equation with respect to l,

dP/dl = 2 - 2A/l²

when dP/dl = 0 we get,

2 - 2A/l² = 0

l = √A

Substitute l = √A in the area equation,

A = w√A

w = A/√A

w = √A

This means, l = w = √A

Since length is equal to width, then it is a square.

We have been given that the area is 60,000 m²

So, l = w = √(60,000)

l = w = 244.95 m

Therefore, the lengths of the sides of the rectangular field should be 244.95 m
