So how you do scientific notation is, however many places you move the decimal point to the left is the number that you put in the power. For example, Mercury's mass is 330,000,000,000,000,000,000,000. You move the decimal point 23 places to the left to get 3.3 x 10^23. ( ^ means power. The little number that is next to the 10)
Now according to the question, the mass of Jupiter is 5.8 x 10^3 multiplied by 3.3 x 10^23 (5,800 x 330,000,000,000,000,000,000,000).
The answer to part A is,
1,941,000,000,000,000,000,000,000,000
Then, 3.2 x 10^2(X)=5.8 x 10^3 x 3.3 x 10^23
I don't know if you know how to do algebra, but this is very simple to solve. All you do is divide bolth sides of the equation by 3.2 x 10^2 leaving X (Earths mass) on the left.
For the right side need to divide 320 by 1,941,000,000,000,000,000,000,000,000. This will be the answer to part B
Hopefully this was helpful enough for you to show your work. Good luck : )
Answer:
8x+10y
Step-by-step explanation:
What you do first is you need to subtract -2y from 9y to get 7y.
So you have (12x+7y)-(4x-3y). The negative sign needs to be added into the problem so it will be (12x+7y)+(-4x+3y). You will then add and minus them together to get 8x+10y.
Answer:
15-7 = 8
-12 * -7 = 84
8 +84 = 92
92-8 = 84
84

Answer:
Step-by-step explanation:
PEMDAS is a set of rules which are followed while solving mathematical expressions. These rules start with Parentheses, and then operations are performed on the exponents or powers. Next, we perform operations on multiplication or division from left to right. Finally, operations on addition or subtraction are performed from left to right.
The statement which best describes the similarity of the two triangles is; Choice D; There is not enough information to determine whether the triangles are similar.
<h3>Which statement best explains whether △ABC is similar to △DEF?</h3>
The two triangles given in the task content are expected to be assessed to determine if they are similar.
From the concept of congruence in triangles, two triangles are congruent only if all 3 angle measures in one are similar to that in the other, or if the ratio of all corresponding pairs of sides are equal.
Hence, since neither of the conditions is satisfied by the information given, it follows that Choice D is correct.
