The dwarf seahorse hippocampus zosterae swims at a rate of 52.68 feet per hour.convert this speed to ines per minute

DaniilM [7]

<h3>52.68 feet per hour = 10.536 inches per minutes</h3>

<h3>Further explanation</h3>

Acceleration is rate of change of velocity.

$\large {\boxed {a = \frac{v - u}{t} } }$

$\large {\boxed {d = \frac{v + u}{2}~t } }$

<em>a = acceleration ( m/s² )</em>

<em>v = final velocity ( m/s )</em>

<em>u = initial velocity ( m/s )</em>

<em>t = time taken ( s )</em>

<em>d = distance ( m )</em>

Let us now tackle the problem !

$1 ~ foot = 30.48 ~ cm$

$1 ~ inch = 2.54 ~ cm$

$1 ~ foot = 12 ~ inches$

$\boxed {52.68 ~ feet = 52.68 \times 12 ~ inches = 632.16 ~ inches}$

$1 ~ day = 24 ~ hours$

$\boxed {1 ~ hour = 60 ~ minutes}$

If the dwarf seahorse hippocampus zosterae swims at a rate of 52.68 feet per hour , then :

$52.68 ~ feet/h = \frac{52.68 ~ feet}{1 ~ hour}$

$52.68 ~ feet/h = \frac{52.68 \times 12 ~ inches}{60 ~ minutes}$

$52.68 ~ feet/h = \frac{632.16 ~ inches}{60 ~ minutes}$

$\large {\boxed {52.68 ~ feet/h = 10.536 ~ inches/min} }$

An equipment rental company charges a flat rate of $25,plusc$13 per day for insurance.kyle has $121.write an inequality to repre

Sergio [31]

13d+25≤121 represent the inequality to find the number of days.

Step-by-step explanation:

Flat rental fee of equipment = $25

No. of days = d

Per day fee = $13

Amount Kyle has = $121

According to given statement,

$13d+25\leq 121$

As the amount is $121, therefore, the total cost can either be a total of $121 or less.

13d+25≤121 represent the inequality to find the number of days.

How long a rope is required to reach from the top of a building 40 feet high 30 feet from the base of the building?

Goshia [24]

70 feet.
If you're 30 feet from the base, then you have to climb that 30 feet, plus the 40 foot length of that building. (:
