Answer:

Last week, a coral reef grew 19.5 mm taller. How much did it grow in meters?

Step-by-step explanation:

So it's hard to explain but simply Milli witch is the symbol "m" is a unit prefix in the metric system denoting a factor of one thousandth (10 −3).  So 19.6mm is 19.6*10^-3m.  in other words 19.6 times 10^-3m

hope this helps sorry it's so complicated :/

There are 60 seats on a train. 6 of the seats are empty. What percentage of the seats on the train are empty?
sergij07 [2.7K]

Answer:

10%

Step-by-step explanation:

  1. Set up a proportion: \frac{6}{60} = \frac{x}{100}  
  2. Cross multiply, then divide: 6 × 100 = 600, 600 ÷ 60 = 10
  3. 10/100 = 10%

I hope this helps!

The diameter of a sphere is 4 centimeters. Which represents the volume of the sphere?
soldier1979 [14.2K]

Answer:

32\pi/3 cm³

Step-by-step explanation:

If the diameter is 4 cm, then the radius is 2 cm.

Use the sphere volume formula:

V = 4/3\pir³

Plug in the radius and solve:

V = 4/3\pi(2)³

V = 4/3\pi(8)

V = 32\pi/3

So, the volume of the sphere is 32\pi/3 cm³

Use the arc length formula to find the length of the curve y = 4x − 5, −1 ≤ x ≤ 2. check your answer by noting that the curve is
professor190 [17]
Ok, here we go.  Pay attention.  The formula for the arc length is AL= \int\limits^b_a { \sqrt{1+( \frac{dy}{dx})^2 } } \, dx.  That means that to use that formula we have to find the derivative of the function and square it.  Our function is y = 4x-5, so y'=4.  Our formula now, filled in accordingly, is AL= \int\limits^2_1 { \sqrt{1+4^2} } \, dx (that 1 is supposed to be negative; not sure if it is til I post the final answer).  After the simplification we have the integral from -1 to 2 of \sqrt{17}.  Integrating that we have AL= \sqrt{17}x from -1 to 2.  2 \sqrt{17}-(-1 \sqrt{17} ) gives us 3 \sqrt{17}.  Now we need to do the distance formula with this.  But we need 2 coordinates for that.  Our bounds are x=-1 and x=2.  We will fill those x values in to the function and solve for y.  When x = -1, y=4(-1)-5 and y = -9.  So the point is (-1, -9).  Doing the same with x = 2, y=4(2)-5 and y = 3.  So the point is (2, 3).  Use those in the distance formula accordingly: d= \sqrt{(2-(-1))^2+(3-(-9))^2} which simplifies to d= \sqrt{9+144}= \sqrt{153}.  The square root of 153 can be simplified into the square root of 9*17.  Pulling out the perfect square of 9 as a 3 leaves us with 3 \sqrt{17}.  And there you go!
