A suspension bridge spans a river 1350 ft. wide. 30% of the bridge is on one side of the river and 25% is on the other side. The total length of the suspension bridge is ft.

The world's longest suspension bridges are listed according to the length of their main span (i.e. the length of suspended roadway between the bridge's towers). The length of main span is the most common method of comparing the sizes of suspension bridges, often correlating with the height of the towers and the engineering complexity involved in designing and constructing the bridge.[1] If one bridge has a longer span than another it does not necessarily mean that the bridge is longer from shore to shore (or from abutment to abutment).

Suspension bridges have the longest spans of any type of bridge. Cable-stayed bridges, the next longest design, are practical for spans up to just over 1 kilometre. Therefore, as of 2021, the 29 longest bridges on this list are the 29 longest spans of all types of vehicular bridges (other than floating pontoon bridges).

Since 1998 Akashi Kaikyō Bridge in Japan holds the record with its span of 1,991 metres (6,532 ft). The Çanakkale 1915 Bridge of the Dardanelles, currently under construction in Turkey, is expected to surpass it with a span of 2,023 metres (6,637 ft).

Step-by-step explanation:

Do the percent thing to find out how much percent the bridge is missing

then solve to figure it out

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
