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

Using the sum of the angle measures of a triangle, m angleC=?
Vedmedyk [2.9K]

Answer:

m∠C = 66°

Step-by-step explanation:

Given

m∠ A = 33°

m∠ B = 81°

To determine

m∠C = ?

We know that sum of angles of a triangle is 180°.

so using the equation

m∠ A + m∠ B +  m∠C = 180°

substituting m∠ A = 33°, and m∠ B = 81° in the equatio

33° + 81°+m∠C= 180°

114° + m∠C = 180°

m∠C = 180° - 114°

m∠C = 66°

Therefore,

  • m∠C = 66°

Select all that apply.
Lelechka [254]

Answer: The second option and the third option are true.

Step-by-step explanation:

The formula of the line in slope-intercept form is:

y=mx+b

Where <em>m </em>is the slope and <em>b </em>is the y-intercept.

By definition, the y-intercept in a direct variation is 0.

Therefore, substituting m=-3 and b=0 into the equation, you obtain:

y=-3x+0

Then, the equation is:

y=-3x

As this is a line, it is a linear function.

Therefore, the second option and the third option are true.

Two architects bid for a small government project, both
blondinia [14]

Answer:

10 hours

Step-by-step explanation:

let x be the total number of hours

Amazing design total charge = 45x+250

super structures total charge = 60x+100

both companies charge the same amount when both equation equals

45x+250=60x+100

60x-45x=250-100

15x=150

x=10

therefore at 10 hours both companies will charge the same amount
