1. what is the mass, in Kilograms, of a star that is 1.5×10^2 times thw mass of the sun? The sun's mass is 2.0×10^30 kg. Express the answer in Scientific notation. 2. Solve Apply the concepts to this problem. Set up the problem. (2.0 X 10^30) X (1.5 X 10^2) Multiply the coefficients. (2.0 X 10^30) X (1.5 X 10^2), (2.0 X 1.5) = 3.0 Then add the exponents. (2.0 X 10^30) X (1.5 X 10^2) = (10^30 X 10^2) = 10^30 + ^2 = 10^32, Combine the results of the two operations. (2.0 X 10^30) X (1.5 X 10^2) = 3.0 X 10^32 The star's mass is 3.0 x 10^32 kg. * Muliply numbers written in Scientific notation by multiplying the coefficients and then adding the exponents. you will get Free huge point and a Crown!

1.   The star's mass is 3.0 x 10^32 kg.

2.  The star's mass is 3.0 x 10^32 kg.

Step-by-step explanation:

1.

given:

The sun's mass is 2.0×10^30 kg.

mass of a star = 1.5×10^2 kg times the mass of the sun.

find:

Express the answer in Scientific notation.

mass of a star =  1.5×10^2 kg X 2.0×10^30 kg

mass of a star = 3.0 X 10^32 kg

therefore,

The star's mass is 3.0 x 10^32 kg.

2.

(2.0 X 10^30) X (1.5 X 10^2)

Multiply the coefficients.

= (2.0 X 1.5)

= 3.0

then add the exponents

= 10^30 + 10^2

= 10^32

Combine the results of the two operations.

(2.0 X 10^30) X (1.5 X 10^2) = 3.0 X 10^32

therefore,

The star's mass is 3.0 x 10^32 kg.

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
