John ran the 100-m dash with a time of 9.82 sec. if this pace could be maintained for an entire 26 dash mi marathon, what would his time be? (notice that 1 m almost equals 3.281 ft and 1 mi equals 5280 ft. right parenthesis

we know that

1 m almost equals 3.281 ft

1 mi equals 5280 ft

so

step 1

Convert 100 m to ft

Multiply 100 by 3.281

100*3.281=328.1 ft

step 2

Convert 328.1 ft to miles

Divide 328.1 by 5280

328.1/5280=0.0621 miles

step 3

Find the time

we know that

100 meter is equal to-------> 0.0621 miles

John ran the 0.0621 miles dash with a time of 9.82 sec

Find the time for 26 miles

by proportion

convert to hour

we know that

1 hour is------------> 3,600  sec

4,111.43 sec is-----------> 4,111.43/3,600=1.14 hour

4,111.43 sec=1 hour+(4,111.43 sec-3,600 sec)------> 1 hour+511.43 sec

convert to minutes

we know that

1 minute is ---------> 60 sec

511.43 sec=511.43/60-------------> 8.52 min

511.43 sec=8 min+(511.43 sec-8*60 sec)------> 511.43 sec=8 min+31.43 sec

therefore

the total time is equal to

4,111.43 sec= 1 hour +8 min+31.43 sec

the answer is

1 hour +8 min+31.43 sec

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
