Pls answer for my hw thanks

27.86 cm

Step-by-step explanation:

use a^2+b^2=c^2

plug in 10 to a and 26 to b

so

10^2+26^2=c^2

then simplify

100+676=c^2

776=c^2

then find the square root of 776 which is 27.856... cm

this can be simplified to 27.86 cm

change it to 28 cm if your teacher wants it rounded to the whole number

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.
