Answer:

1000 times

First, we estimated the Sun's width in terms of the Earth's breadth, then the Star's width in terms of the Earth's breadth, and for comparison, we did simple division, which revealed that the Star KW Sagittarii is 1000 times wider than the Sun.

What is the perimeter of a square whose diagonal is 13.010
miskamm [114]

The perimeter would be ≈ 36.797836892947.

Rounded would be about 37, or 36.8.

Hope this helps!!!!

P=4a

d\sqrt{2a}

Solving for P:

P=2\sqrt{2d} =2*\sqrt{2*13.01}≈36.79784

Hope this helps!!

How do I solve this question?
Tanya [424]
Before attempting to solve this question, we must first know three things.

1. A straight line has a measure of 180 degrees.

2. When two angles add up to 180 degrees, those angles are called supplementary.

3. The interior angles of a triangle add up to 180 degrees.

We can see ∠ECT = 180 degrees.

∠DCT is supplementary to ∠DCE.

∠DCT = 140 degreees
∠DCE = x degrees

x + 140 = 180

Solve for x.

x + 140 = 180
x = 40 <-- Subtract 140 from each side

∠DCE = 40 degrees

We know the two interior angles of ΔDEC.

45 + 40 + x = 180

Solve for x.

45 + 40 + x = 180
85 + x = 180 <-- Combine like terms
x = 95

So, the missing angle is equal to 95 degrees.

Where is water found in... lithosphere, asthenosphere, the mental, or earths core?​
erica [24]

Answer:

Water is stored in the following places: The lithosphere (the solid outer crust and upper mantle). In oceanic crust it is stored within the rock structure which it is composed of and in continental crust it is also found in rocks, minerals, and also in clay and as groundwater.

I say the lithosphere.

Step-by-step explanation:

or it can be

But new research suggests a different origin for the oceans: they simply seeped out of the center of the Earth. The finding, published in Science, suggests that a reservoir of water is hidden in the Earth's mantle, more than 400 miles below the surface.

If something cost $100 and it's 100% off how much will it cost
SVETLANKA909090 [29]
Well 100% off of something means that it is all off I think.
You make 100% a decimal and multiple that which you get .100 by 100 and get 10 as your total...

I think that's right but not sure
