An engineer is building a bridge that should be able to hold a maximum weight of 1 ton. He builds a model of the bridge that is exactly 4 times smaller than the actual bridge. 16 ounces = 1 pound. 2,000 pounds = 1 ton. If a test of the model shows that it holds 8,000 ounces, will the bridge hold 1 ton? 8,000 ounces on the model is equal to ounces on the actual bridge. Convert ounces to pounds. The actual bridge can hold pounds. Therefore, the bridge hold 1 ton.

The bridge can hold 1 ton

Step-by-step explanation:

Given that :

Model of bridge built is exactly 4 times smaller than actual bridge

Model bridge : actual bridge

1 : 4

From test,

Model bridge can hold 8000 ounces

Since actual bridge is 4 times the model bridge,;

Then, actual bridge should hold (8000 * 4) ounces = 32000 ounces

16 ounces = 1 pound

2000 pound = 1 ton

Hence,

32,000 ounces = (32000 / 16) pounds = 2000 pounds

Hence,

2000 pounds = 1 ton

the first option i believe

step-by-step explanation:

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
