PLEASE HELP, WILL GIVE 20 POINTS.

Answer: 200cm^{2}

Step-by-step explanation:

To double the dimensions, you must multiply both the length and width by 2, so instead of just l*w=a, you have 2l*2w=b, which can be simplified even further to 2*2*l*w=b

Now, multiply the 2s together to get 4, making the equation 4lw=b. Since lw is a, and b is 4 times as much as a, you just need to multiply the original area by 4 to get the new area.

(_2/3)(Raised to power 3) multiplied by (_3/2)(raised to power 2)
Irina18 [472]

Answer:

\frac{-2}{3}

Step-by-step explanation:

From the given question,

(\frac{-2}{3} )^{3} x (\frac{-3}{2} )^{2}

Applying the required principle of indices to solve the question, we have;

(\frac{-2}{3} )^{3} x (\frac{-3}{2} )^{2} = \frac{(-2)^{3} }{3^{3} } x \frac{(-3)^{2} }{2^{2} }

= \frac{-8}{27} x \frac{9}{4}

= \frac{-72}{108}

= \frac{-2}{3}

Thus, the final answer is \frac{-2}{3}.

Explain how finding 7×20 is similar to finding 7×2,000 . then Find each product
3241004551 [841]
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.

Calvin cleans \dfrac35 ​5 ​ ​3 ​​ start fraction, 3, divided by, 5, end fraction of his bathroom with \dfrac13 ​3 ​ ​1 ​​ start
Brums [2.3K]
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.

An archer shoots an arrow up towards a target located on a hill, which is shown by the graph. Which set of equations best models
Gekata [30.6K]

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.
