<u><em>Answer:</em></u>

The bird will have traveled 403 meters in 13 seconds if it maintained a speed of 31 m/sec

<u><em>Explanation:</em></u>

<u>The equation that relates velocity, distance and time is:</u>

velocity = \frac{distance}{time}

<u>This means that:</u>

distance = velocity * time

<u>In the given, we have:</u>

velocity = 31 m/sec

time = 13 sec

<u>Substitute with the givens in the above equation and solve for the distance as follows:</u>

distance = velocity * time

distance = 31 * 13

distance = 403 meters

Hope this helps :)

The value of x in the triangle is 9.3

<h3>How to find the side x of a triangle?</h3>

The side x of a triangle can be found as follows:

The triangle ABC is similar to triangle ADE.

Therefore, corresponding sides of similar triangles are in the same ratios.

Hence,

7  / 13 = x / x + 8

cross multiply

7(x + 8) = 13x

7x + 56 = 13x

subtract 7x from both sides of the equation

7x - 7x + 56 = 13x - 7x

56 = 6x

divide both sides by 6

x = 56 / 6

x = 9.33333333333

x = 9.3

Machine A working alone can complete a job in 3 1/2 hours. Machine B working alone can do the same job in 4 2/3 hours. How long
SIZIF [17.4K]

Answer:

B) 2 hours

Step-by-step explanation:

If machine  A complete a job in 3 1/2 hours or 7/2 of an hour

means that in one hour finished 1÷ 7/2     or  2/7

If machine  B complete a job in 4 2/3 hours or  14/3 of an hour

means that in one hour finished 1÷ 14/3    or  3/14 of an hour

Then the two machines working together in one hour will make

2/7 + 3/14    =  (4 + 3)/ 14

or   7/14   = 1/2

half of the job. Therefore these two machines working together will take two hours

Which undefined term is needed to define an angle?<br><br> Plane<br> Point<br> Ray<br> Line
Aleks04 [339]

Point.

<h3>Further explanation</h3>
  • The angle is determined by three points, we call it A, B, C, with A ≠ C and B ≠ C.  
  • We express an angle with three points and a symbol ∠. The middle point represents constantly vertex. We can, besides, give angle names only with vertices. For example, based on the accompanying image, the angle can be symbolized as ∠BAC, or ∠CAB, or ∠A.  

<u>Note:  </u>

This is one of the classic problems of Euclidean geometry.

Undefined terms are the basic figure that is undefined in terms of other figures. The undefined terms (or primitive terms) in geometry are a point, line, and plane. These key terms cannot be mathematically defined using other known words.

  • A point represents a location and has no dimension (size). It is marked with a capital letter and a dot.
  • A line represents an infinite number of points extending in opposite directions that have only one dimension. It has one dimension. It is a straight path and no thickness.
  • A plane represents a planar surface that contains many points and lines. A plane extends infinitely in all four directions. It is two-dimensional. Three noncollinear points determine a plane, as there is exactly one plane that can go through these points.
