The statement below describes a situation in which opposite quantities combine to make zero:

A cup with a hole in it loses 2 ounces of water in the first minute and then loses 2 ounces of water in the second minute.

True
False

Answers

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

the ratio of a shorter walkway to a longer walkway is 3 to 5. the lenght of the sorter walkway is 45 meters. what is the lenght of the longer walkway

Answers

Answer:

75 m

Step-by-step explanation:

Let s- shorter walkway, l- longer walkway.

Given:

s/l = 3/5s = 45 m

Find the length of l:

45/l = 3/5l = 45*5/3l = 75 m

Answer:

[tex]\sf\longmapsto \: length = 75 \: metres[/tex]

Step-by-step explanation:

Now let's find out what's the length of the long walkway–

[tex]\sf\longmapsto \: \frac{3}{5} = \frac{45}{\: length\: of \:longer\: walkway} [/tex]

[tex]\sf\longmapsto \: \: length\: of \:longer\: walkway= \frac{45 \times \: 5 }{3} [/tex]

[tex]\sf\longmapsto \: length\: of \:longer\: walkway= 75 \: metres[/tex]

The length of the longer walkway is [tex]\sf\longmapsto \: length = 75 \: metres[/tex]

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.

What is the Circumcenter of a 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.
