Answer:

B, π:(4-π).

Step By Step:

With a side of length 12, we have an area of 144. The circle's radius is 3, so their area is 9π, per circle. All four circles have a total combined area of 36π  - green. The area that is left of the square after the circles are painted green  is  144-36π - White

So, the ratio of Green:White is (36π) : (144-36π), which simplifies to π:(4-π), B

A sound wave travels through iron at a rate of 5120 m/s. At what rate does the sound wave travel in km/h
marissa [1.9K]
<span>When converting a number with meters per second to a value with kilometers per second they best way to perform this operation is by using dimensional analysis or the factor label method. You would set up the equation starting with 5120 m/s times 1 km / 1000 m times 3600 s / 1 hr. It would look like this: (5120 m/ 1 s) x (1 km / 1000 m) x (3600 s / 1 hr) Your next step would be multiplying all the top numbers (numerators) together 5120 x 1 x 3600 = 18,432,000 Now multiple on the bottom numbers (denominators) together 1 x 1000 x 1 = 1000 Now you can divide the top product by the bottom product. 18,432,000 / 1000 = 18,432 km/hr is your final answer.</span>

Answer:

  8.284 × 10^4 m^2

Step-by-step explanation:

The area is the product of length and width:

  (5.45·10^5 m)·(0.152 m) = 0.8284·10^5 m^2 = 8.284·10^4 m^2

Help me if you understand thanks sm

First, find the slope of the line using the formula for slope:

m = (y2 - y1) / (x2 - x1)

m = (4 - (-2)) / (-3 - 2) = -6/5

Then, use the point-slope formula using a point that you were given and the slope that you calculated.

y - y1 = m(x - x1)

y - 4 = (-6/5)(x + 3)

Then, simply get y alone.

y = (-6/5)x + 2/5
