Hitman42 [59]

Answer:

In 1 min a gazelle runs 3,900 ft.

As a fraction, 1/65

In order to find the solution to this problem you could use a table.

Since we are using seconds we have to convert the 1 min = 60 seconds.

<u>Sec</u><u>   |  12    |    60</u>

<u>Fts</u><u>    |  780  |    x  </u>

12 goes into 60 5 times, so we have to multiply 780 by 5 which gives us 3900.

x=3900

Answer:

The length of mid-segment XY=4 units

Step-by-step explanation:

Given:

Length of QR=8 units

XY is the mid-segment which means the line joining the midpoints of two sides of triangle.

By mid-segment theorem the mid-segment of a triangle is parallel to the third side and half of the length of third side.

So, we can write:

XY=\frac{1}{2}QR  

XY=\frac{1}{2}(8)

∴ XY=4 units

∴The length of mid-segment XY=4 units
