What is the best way to learn percentage?

1 answer:

juin [17]3 years ago

Answer: To write a percentage as a decimal, simply divide it by 100. For example, 50% becomes 0.5, 20% becomes 0.2, 1% becomes 0.01 and so on. We can calculate percentages using this knowledge. 50% is the same as a half, so 50% of 10 is 5, because five is half of 10 (10 ÷ 2).

A net and 4 figures are shown. Which figure shown can be formed from the net. ( input the number only) please answer quick and e

AfilCa [17]

A net is pretty much a three dimensional shape unfolded into a flat construction. Imagine cutting the edges of a box and unfolding it so you can lay it flat on the ground. That would form a net for the 3D shape of the box.
In this case, 1 and 2 obviously aren't right since they would both involve triangles in their net. 3 is close, but the parts of the net wouldn't be completely equal. Therefore it has to be 4, the cube.

Step-by-step explanation:

6x+2y=12

2y=6x-12

y=6x/2- 12/2

Office equipment was purchased for $20,000 and is assumed to have a scrap value of $2,000 after 10 years. If its value is deprec

boyakko [2]

According to the information given in the exercise:

- The office equipment was purchased for $20,000.

- The scrap value is assumed to be $2,000 after 10 years.

- -It's depreciated linearly from $20,000 to $2,000.

(a) The Slope-Intercept Form of the equation of a line is:

$y=mx+b$

Where "m" is the slope of the line and "b" is the y-intercept.

Let be "V" the value (in dollars) and "t" the time (in years).

Analyzing the information given in the exercise, you can set up that the equation will have this form:

$V=mt+b$

Where "m" is the slope and "b" is the y-intercept.

Notice that you have these two points:

$\begin{gathered} (0,20000) \\ (10,2000) \end{gathered}$

Then, you can apply the formula for calculating the slope:

$m=\frac{y_2-y_1}{x_2-x_1_{}}$

You can say that:

$\begin{gathered} y_2=2000 \\ y_1=20000 \\ x_2=10 \\ x_1=0 \end{gathered}$

Substituting and evaluating, you get:

$m=\frac{2000-20000}{10-0}=\frac{-18000}{10}=-1800$

To find "b", you need to remember that the value of "x" is zero when the line intersects the y-axis. Therefore, knowing that one of the points is:

$(0,20000)$

You can determine that:

$b=20000$

Hence, the equation is:

$V=-1800t+20000$

(b) To find the value of the equipment after 6 years, you need to set up that:

$t=6$

Then, substituting this value into the equation and evaluating, you get:

$\begin{gathered} V=-1800(6)+20000 \\ V=9200 \end{gathered}$

Therefore, the answers are:

(a)

$V=-1800t+20000$

(b) $9,200

If they were part of the same expression, which of the following would be considered like terms with the given monomial?

dedylja [7]

Answer: OPTION B

Step-by-step explanation:

The like term of the given monomial $5m^2n$ must have the following characteristics:

- The exponent of "m" must be "2".

- The exponent of "n" must be "1".

Then, you can observe that the option that shows a monomial with this characteristics is the option B.

Therefore, the like term with the given monomial $5m^2n$ is:

$-m^2n$
