3 5/6 + 4 1/6 =
add the whole numbers....3 + 4 = 7
add the fractions....5/6 + 1/6 = 6/6 = 1

add them together....7 + 1 = 8 hrs <===

a blue arlin can swim at 50miles per hour. What is that speed in feet per second , to the nearest whole number ?

morpeh [17]

Step-by-step explanation:

Multiply the amount of feet in one mile by the amount of miles in the question(5,280 x 50 = 264,000)

Divide the amount of feet in 50 miles by the amount of minutes in 1 hour to get the amount of feet per mile (264,000 ÷ 60 = 4,400)

Divide the amount of feet per mile to get by the amount of seconds in a minute to get the amount of feet per second (4,400 ÷ 60 = 73.33)

Your answer rounded to the nearest whole number is 73

Tiffany kicks a soccer ball off the ground and in the air, with an initial velocity of 28 feet per second. Using the formula H(t

Sedaia [141]

Answer:

The maximum height of soccer ball is 12.25 ft.

Step-by-step explanation:

It is given that Tiffany kicks a soccer ball off the ground and in the air, with an initial velocity of 28 feet per second. It means v = 28 ft.

Given formula is

$H(t)=-16t^2+vt+s$

The initial height of ball is 0.

$H(0)=-16(0)^2+v(0)+s$

$0=s$

The height of ball defined by the function

$H(t)=-16t^2+(28)t+0$

$H(t)=-16t^2+28t$

It is a downward parabola and the vertex of a downward parabola is the point of maxima.

The vertex of a parabola $f(x)=ax^2+bx+c$ is

$(\frac{-b}{2a},f(\frac{-b}{2a}))$

$\frac{-b}{2a}=\frac{-28}{2(-16)}=0.875$

$H(0.875)=-16(0.875)^2+28(0.875)=12.25$

Therefore the maximum height of soccer ball is 12.25 ft.
