It is estimated that 28.5% of automobile crashes are caused by driver distractions, such as texting. If there are 16,390 automobile crashes in a study, what number would be caused by driver distractions? Round to the nearest whole number.

4671 crashes in the study are caused by driver distractions.

Step-by-step explanation:

ok so you need to do a ratio table.

=

Next multiply 16390 by 28.5: 16390*28.5=467115. And then divide that by 100: 467115/100=4671.15 which rounded to the nearest whole number is 4671 crashes.

=

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
