find the surface area a planet if its circumference is about 18,000 miles long. Round to the nearest thousand square miles

Mathematics
1 answer:
Furkat [3]2 years ago

The surface area of the planet is 103,184,713.4 miles².

<h3>What is the surface area?</h3>

A planet has the shape of a sphere.

The first step is to determine the radius of the planet from the circumference.

Radius = circumference / (π x 2)

18,000 / (3.14 x 2) = 2,866.24 miles

Surface area of a sphere = 4πr²

4 x 3.14 x ( 2,866.24²) = 103,184,713.4 miles²

Jafar has a fruit basket with 13 pieces of fruit. He has 1 orange, 5 apples, 4 kiwis, and 2 pears in the basket. He also has ban
mars1129 [50]
<h3>Hello there!</h3><h3>Answer: 1/13</h3>

1/13 would represent the amount of bananas in the basket.

There would be only 1 banana because it would complete he amount of fruits in the basket.

In the basket, we know that there are:

1 orange + 5 apples + 4 kiwis + 2 pears = 12

That would be 12 fruits, but there are suppose to be 13 fruits, which means that the remaining 1 fruit would be a banana.

So, that means that the amount of bananas in the basket is 1 out of 13, or 1/13.

<h3>I hope this helps!</h3><h3>Best regards,</h3><h3>MasterInvestor</h3>

I suck at math please help lol
sasho [114]

Answer:

1

Step-by-step explanation:

since the 2 functions equal each other:

-2x + 3 = 4x - 9

add -2x to both sides

3 = 6x - 9

add 9 to both sides

12 = 6x

divide by 6

2 = x

you have x, now find y, you just need to plug 2 into one of the equations instead of both bc they both equal the same anyway

-2(2) + 3

-4 + 3

-1 = y

Now we'll find x + y, input them and it's 2 + (-1), which is 1

What is the equation of the line with slope of - 1/3 and passes through the point (6, -3)?
AURORKA [14]

-1 - ⅓x = y is the answer because of this:

Point-Slope Formula FIRST [GIVEN BOTH SLOPE AND A POINT]: y + 3 = -⅓(x - 6) ["+" was inserted because of (-(-3)) = 3]

Distributive Property: y + 3 = ⅓x + 2

Final Result [deduct 3 from both sides of the equation]: -1 - ⅓x = y (OR y = ⅓x - 1)

You get it?
