We know that
The distance <span>from the sun to earth is equal to 1 AU
1 AU (</span>Astronomical Unit) is equal to <span>150 million km

in this problem
by proportion
8 min/1 AU=240 min/x
8*x=240
x=30 AU

convert to km
30*</span>150 million km-----> 4500 million km
<span>
the answer is
</span>the distance from the sun to neptune is 30 AU (4500 million km)<span>

</span>

Ok i have a few questions please give examples and descriptions as well
Arte-miy333 [17]

Answer:

1) Multiplying powers with the same base would be product rule. It where you just add the exponents. Dividing powers with the same base would be the quotient rule. Its where you subtract the exponents.

2)Where you multiply the two exponents together

3)The negative law is where for example, if it were in the numerator, then it would be placed at the denominator with a positive exponent whereas if it were in the denominator it would be on the numerator with the positive exponent. The zero law just states the anything to the power to zero is one.

Step-by-step explanation:

1) 3^3 x 3^4 = 3 ^3+4 = 3^7

3^9 ÷3² = 3^9-2 = 3^7

2) (3^2)^2 = 3^2×2 =3^4

3) 1/3^-5 = 3^5                 \

3^-7 =1/3^7

2^0 = 1

The circumference of a circle is 18.84 miles. What is the circle's radius? C=18.84
Mama L [17]
We can find the radius by using the formula: C = 2(pi)(r)
We'll use 3.14 for pi.

And solve for r.

18.84 = 2(3.14)r ; Start
18.84 = 6.28r      ; Multiply 3.14 by 2
3 = r                     ; Divide both sides by the coefficient of r. Which is 6.28

So, the radius is 3 miles.
