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.

look at the time for example, B's time is constant because it isn't skipping numbers like 1, 5, 3,etc.

the height is also constant because it is dividing each number by 2, 60÷2=30, 30÷2=15, 15÷2=7.5. You will notice A is not constant so (no) but B is so (yes)

Answer: False

Step-by-step explanation:

A cup with a hole in it loses 2 ounces of water in the first minute. This mathematically means

Add -2 (loses ⇒ means getting less)

Then the cup loses 2 ounces of water in the second minute. This mathematically means

Add -2 (loses ⇒ means getting less)

In total,  and means loses 4 ounces in two minutes.

Thus, the statement below does not describe a situation in which opposite quantities combine to make zero, so this statement is false

Answer:

20 yards squared.

Step-by-step explanation:

First, you should convert your units. Three feet make a yard, so 15 feet = 5 yards and 12 feet = 4 yards.

The area of a square is found by multiplying the length and width, so 5 yards x 4 yards = 20 yards.

Answer:

2 x 7 x 3²

Step-by-step explanation:

When finding primes, you use the method I attatched as a picture. Start with the large number at the top, slowly dividing it by factors of it.

The picture shows that the primes 126 is a product of is:

2, 7, 3, 3

Or:

2 x 7 x 3 x 3

This can be simplified into:

2 x 7 x 3²

Hope this helps!

Answer:

Write 126 as a product of primes.

Use index notation when giving your answer.

The perimeter of a shape is the sum of its side lengths.

Joshua miscalculated the third length of the triangle

First, we calculate the third length (x) of the triangle.

Because the triangle is right-angled, we can make use of Pythagoras.

So we have:

[tex]x^2 = 7^2 + 7^2[/tex]

[tex]x^2 = 2(7^2)[/tex]

Take square roots of both sides

[tex]x = \sqrt{2(7^2)[/tex]

[tex]x = 7\sqrt{2[/tex]

The other shape in the figure is a square.

So, the perimeter (P) is

[tex]P = 7 + x + x + x + 7[/tex] ---- i.e. the sum of the visible lengths

So, we have:

[tex]P = 7 + 7\sqrt2 + 7\sqrt2 + 7\sqrt2+ 7[/tex]

Evaluate like terms:

[tex]P = 14 + 21\sqrt2[/tex]

Hence, Joshua's error is that:

He miscalculated the third length of the triangle
