answer:

14.7

step-by-step explanation:

21/100=0.21

0.21*70=14.7

answer:

585 miles

step-by-step explanation:

we can use the formula  

distance = rate * time

we know the time = 540 minutes and the rate = 65 miles per hour

the units are not the same   so convert the 540 minutes to hours

1 hour = 60 minutes

540 minutes * 1 hour/60 minutes =   9 hours

distance = 65 miles / hour * 9 hours

              = 585 miles

answer:

15.59 feet

step-by-step explanation:

we need to find bc and cd

first find bc

we can use the pythagorean theorem

ab^2 + bc^2 = ac^2

11^2 + bc^2 = 13^2

121 + bc^2 =169

subtract 121 from each side

121-121+bc^2 = 169-121

bc^2 = 48

take the square of each side

sqrt(bc^2 ) = sqrt( 48)

bc = 6.92820323

then we need to find cd

we can use the pythagorean theorem

cd^2 + de^2 = ce^2

cd^2 + 5^2 = 10^2

cd^2 + 25 =100

subtract 25 from each side

cd^2 + 25-25 =100-25

cd^2 = 75

take the square of each side

sqrt(cd^2 ) = sqrt( 75)

bc = 8.660254038

bd = bc +cd

      = 6.92820323 + 8.660254038

      15.58845727
