Answer:

Step-by-step explanation:
From the given question,
x 
Applying the required principle of indices to solve the question, we have;
x
=
x 
=
x 
= 
= 
Thus, the final answer is
.
7x20=140. 7x2000=14000. The only thing that changes the product of these numbers is the amount of zeros behind the 2. Since the only two numbers that affect the answer is the 7 and the 2. (7x2=14). The number of zeros behind the 2 affect how many zeros will be included in the product.
We are given with:
3/5 of the bathroom is cleaned by 1/3 of a bottle of cleaning solution.
This problem involves the use of ratio and proportion. If we let x as the fraction of the bottle of cleaning solution needed to clean the entire bathroom, then we have the equation:
1 / x = 3/5 / 1/3
Solving for x
x = 5/9
The bathroom needs 5/9 of the bottle of cleaning solution.
The set of equations best models the point of intersection of the arrow and the target is:
y = –0.008x² + 0.2x + 7 and y = 0.12x.
<h3>What are the equations of the point of intersection?</h3>
To find the equations, we have to look at two things.
- The coordinates of the point.
- The behavior of the arrows trajectory, that is, if it's concave up or concave down.
The coordinates of the point are (35, 4.2), hence the best linear representation is:
y = 0.12x.
This leaves the first two options. The trajectory is concave down, which removes the second option, hence the correct option is:
y = –0.008x² + 0.2x + 7 and y = 0.12x.

3x +0 can be replaced by 3x because of "the additive identity property of real numbers: anything plus zero is that thing."
