Answer:

N=6

Step-by-step explanation:

You need to prime factorize 150. 150 = 3*5*2*5.

x*x=perfect square.

What we have done so far is we have split 150 into a few digits

You can add 5 to one box and 5 to the other.

Next if we add 3 to one box and 2 to the other box, then they wont be equal.

Let's try 5*6 and 5.

6 is missing from the second box, so N must be 6 to create a perfect square.

The perfect square is 900 and 30*30 = 900, so it is a perfect square.

Find the area of the figure.( sides meet at right angles.)picture below
Tema [17]

You can divide the figure as follows:

  • A vertical rectangle, 5 meters tall and 2 meters wide, on the top right.
  • A horizontal rectangle, 2 meters tall and 5 meters wide, on the bottom left
  • A 2x2 meters square on the bottom right, where the two rectangles meet.

The area of the rectangles is 5x2=10 meters squared, while the area of the square is 2x2=4 meters squared.

So, the total area is 10+4=14 meters squared.

Please help me answer thanks.
Dmitry_Shevchenko [17]

Answer:

see explanation

Step-by-step explanation:

Given that M is directly proportional to r³ then the equation relating them is

M = kr³  ← k is the constant of proportion

To find k use the condition when r = 4, M = 160, thus

160 = k × 4³ = 64k ( divide both sides by 64 )

2.5 = k

M = 2.5r³ ← equation of variation

(a)

When r = 2, then

M = 2.5 × 2³ = 2.5 × 8 = 20

(b)

When M = 540, then

540 = 2.5r³ ( divide both sides by 2.5 )_

216 = r³ ( take the cube root of both sides )

r = \sqrt[3]{216} = 6
