Second one , when graphing a linear inequality on a number line, use an open circle for "less than" or "greater than". And a closed circle for "less than or equal to" or "greater than or equal to". Since the arrow is pointing n < -1 it means less than. If it was pointing n > -1 it would be greater than

It’s the second one. The symbol means “less than or equal to,” so it would be a closed circle with the arrow pointing to everything less than -1

Acceleration of 10kg Maas's pushed by a 5n force
malfutka [58]

Answer:

<h3>The answer is 0.5 m/s²</h3>

Step-by-step explanation:

To find the acceleration of an object given it's mass and the force acting on it can be found by using the formula

acceleration =  \frac{force}{mass}  \\

From the question

force = 5 N

mass = 10 kg

So we have

acceleration =  \frac{5}{10 }  =  \frac{1}{2}  \\

We have the final answer as

<h3>0.5 m/s²</h3>

Hope this helps you

What is 40% of $20? Show your work.
bekas [8.4K]

Answer:Thus, a product that normally costs $20 with a 40 percent discount will cost you $12.00, and you saved $8.00. You can also calculate how much you save by simply moving the period in 40.00 percent two spaces to the left, and then multiply the result by $20 as follows: $20 x . 40 = $8.00 savings.

The maximum grade allowed between two stations in a​ rapid-transit rail system is​ 3.5%. Between station A and station​ B, which
azamat

Answer:

Part a) The grade is 3.2%

Part b) This grade meet the rapid-transit rail​ standard

Step-by-step explanation:

we know that

The formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)

In this problem we have

rise=8\frac{1}{2}\ ft=\frac{8*2+1}{2}=\frac{17}{2}\ ft

run=270\ ft

so

\frac{rise}{run}=\frac{17}{2}:270=0.0315

convert to percentage

0.0315*100=3.15\%

Round to the nearest tenth of a percent

3.2\%

3.2\% < 3.5\%

therefore

This grade meet the rapid-transit rail​ standard
