88 feet/second = 60 miles/hour. How many feet per second is 1 mile? (Hint: divide both side of the equation by the same amount.)

zalisa [80]

Answer:

1 mile/hour is equivalent to 1.47 feet/seconds

Step-by-step explanation:

Given

$88 ft/s= 60 miles/hr$

Required

Determine the equivalent of 1 mile/hour

$88\ ft/s= 60\ miles/hr$

Express 60 as 60 * 1

$88\ ft/s= 60 * 1\ mile/hr$

Divide both sides by 60

$\frac{88\ ft/s}{60}= \frac{60 * 1\ mile/hr}{60}$

$\frac{88\ ft/s}{60}= 1\ mile/hr$

Reorder

$1\ mile/hr = \frac{88\ ft/s}{60}$

Divide 88 by 60

$1\ mile/hr = 1.46666666667\ ft/s$

Approximate to 3 significant figures

$1\ mile/hr = 1.47\ ft/s$

Hence;

1 mile/hour is equivalent to 1.47 feet/seconds

Solve for c.<br><br> 3 − 7c − 20c = 7(–7c − 19) + 14c<br><br> c =

OleMash [197]

Answer:

$\boxed{c = -17}$

Step-by-step explanation:

$= > 3 - 7c - 20c = 7( - 7c - 19) + 14c \\ \\ = > 3 - 27c = ( - 7c \times 7) - (7 \times 19) + 14c \\ \\ = > 3 - 27c = - 49c - 133 + 14c \\ \\ = > 3 - 27c = - 35c - 133 \\ \\ = > 3 - 27c + 35c = - 133 \\ \\ = > 3 + 8c = - 133 \\ \\ = > 8c = - 133 - 3 \\ \\ = > 8c = - 136 \\ \\ = > c = - \frac{136}{8} \\ \\ = > c = - 17$

A rocket travels in a trajectory given by the equation s = -4.9t 2 + v0t, where s is meters above ground, t is time in seconds a

Reptile [31]

Step-by-step explanation:

s = -4.9t² + 49t

The vertex of the parabola is at t = -b/(2a).

t = -49 / (2 × -4.9)

t = 5

The rocket reaches its maximum height after 5 seconds.
