The speed of a wave during a tsunami can be calculated with the formula
where
S=square root of 19.812
s represents speed in meters per second, d represents the depth of the water in meters where
the disturbance (for example earthquake) takes place, and 9.81 m/s2 is the acceleration due to
gravity. If the speed of the wave is 150 m/s, what is the approximate depth of the water where
the disturbance took place?

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925

the answer is 31.27mph
