Answer:
38 1/2 meters
Step-by-step explanation:
You have to multiply 28× 1 3/8
You can convert yhe 1 3/8 to an improper fraction, then multiply, and convert back to a mixed number. See image.
OR,
you can distribute the 28 over the sum of 1 and 3/8. This just keeps the fraction a little bit smaller and you can practice distributive property see image

Answer:
The length of the bridge is 126.492 feet.
Step-by-step explanation:
Let , where
is the position from the middle of the bridge, measured in feet, and
is the height of the bridge at a location of x feet, measured in feet. In this case, the length of the bridge is represented by the distance between the x-intercepts of the parabola, which we now find by factorization:
(Eq. 1)
Given that the parabola is symmetrical with respect to y-axis, then the length is two times the magnitude of the value found above, that is:
The length of the bridge is 126.492 feet.

Step-by-step explanation:
The required tools are a compass and straightedge. A pencil or other drawing tool will also be useful (or you can use the marker in the compass).

Generally, follow the applicable directions. The specific directions vary, depending on the construction you want to do. Numerous web sites and videos can show you step-by-step. (Search for "construction of ...") for whatever you're trying to construct.

To construct a circle (or part of a circle), set the compass to the appropriate width, place the pointed end on the center of the circle, and rotate the marker in a circle around that point, taking care to ...
- keep the pointed end in the same spot,
- keep the width of the compass the same until your circle is complete.
To construct a line through two points, align the edge of the straightedge with the two points, and make a mark along that edge using your marking tool. (You may find that you need to make a slight adjustment in your alignment to account for the width of the marker).
All other constructions use combinations of these skills.
