Answer:

≈ 4,22 m

Step-by-step explanation:

volume = 20000L = 20000 dm^3 = 20 m^3

diameter = 2,4m

the volume of a cilinder is π * r^2 * h (height)

20 = π * 1,2^2 * h

h = \frac{20}{\pi * 1,44} \\ ≈ 4,42 m

What is greater 7/10 or 3/6? please show work
vovikov84 [41]
What you need to do is make sure the denominators are the same so multiply 7/10 by 6. It should now be 42/60. Next multiply 3/6 by 10. It should now equal 30/60. 7/10 = 42/60. 3/6 = 30/60. 7/10 is greater. I hope this was somewhat helpful :3

A plane flying over the ocean is on course to land on an aircraft carrier. The diagonal distance between the plane and the aircr
fomenos

Answer:

the plane's current height above the ocean is 3.42 miles

Step-by-step explanation:

Given that the diagonal distance between the plane and the aircraft carrier is 10 miles.

What we need to find is the vertical distance between the plane and the aircraft carrier which is the plane's current height above the ocean. This can be gotten using sine rule.  

For sine rule, you need a side and its opposite angle. For this question the triangle formed is a right angle triangle with diagonal distance, vertical distance and horizontal distance.

let a = diagonal distance = 10 miles

let the opposite angle to the diagonal distance be A = 90° (right angle)

let the vertical distance = b

let the opposite angle to the vertical distance be B = 20°

Sine rule states that    \frac{a}{sin(A)}  =  \frac{b}{sin(B)}

∴   \frac{10}{sin(90)}  =  \frac{b}{sin(20)}

b  =  sin(20)\frac{10}{sin(90)}

b  =  0.342*\frac{10}{1}

⇒ b = 3.42 miles

Therefore the plane's current height above the ocean is 3.42 miles

The expression (x-6)2is equivalent to
Marizza181 [45]

(x - 6) * 2

I'm assuming this is the expression that you typed out, if it isn't, please let me know in the comments :)

Use the distributive property:

= 2(x) - 2(6)

Multiply and simplify

= 2x - 12

This should be the expression that is equivalent to the original. Let me know if you need any clarifications, thanks!
