Answer:

  698 cm²

Step-by-step explanation:

The volume is given by ...

  V = LWH

Filling in the given values, we have ...

  1020 = (17)(5)y . . . . . . . using L=17, W=5, H=y

  y = 1020/(17·5) = 12

The surface area is given by ...

  A = 2(LW +H(L+W))

  A = 2(17·5 +12(17+5)) = 2(85 +264) . . . . . . . using L=17, W=5, H=y=12

  A = 698 . . . . square centimeters

A tug boat traveled -15 miles in 0.3 hours what was its velocity
GenaCL600 [577]

Answer:

22.35 m/s

Step-by-step explanation:

The distance is always a positive unit, so distance traveled (d) = 15 miles

Time (t) = 0.3 hours

Time (t) = 0.3 * 60 = 18 minutes

(1 hour = 60 minutes)

Velocity (v) = ?

The formula of distance is: d = v*t

=> v = d/t = 15/18 = 0.83 miles/minute

we can also calculate velocity is meter/sec, for that

1 minute = 60 sec

=> 18 mins = 18*60 = 1080 sec

1 mile = 1609.34 meters

=> 15 miles = 15 * 1609.34 = 24,140 m

hence,

v = 24,140/1080 = 22.35 m/s

If c+1/d=5 , what is the value of 30d/2c+2
klemol [59]

Answer:

3

d\in R,\hspace{5}d\neq 0

Step-by-step explanation:

You can solve for any variable. From the first equation, let's solve for c :

\frac{c+1}{d} =5\\\\c+1=5d\\\\c=5d-1

Now, replace the value of c into the other equation:

\frac{30d}{2c+2} \\\\\frac{30d}{2(5d-1)+2} \\

Using distributive property

\frac{30d}{10d-2+2} =\frac{30d}{10d} =3

However, keep in mind that this is true for:

d\in R,\hspace{5}d\neq 0
