Answer:

3/4

Step-by-step explanation:

Start from the y-intercept (-1). Find another point that is on the line. I am using the point (0, -1) and also (4, 2).

Next, use the slope form, rise over run. In this case, you can also use the formula (y² - y¹) / (x² - x¹).

Plug in the values, and you get 3/4. So, the slope is 3/4.

Also, you can count from one point of the line up and to the right in this problem to find the slope.

$y=\frac{3}{4} x-1\\$ is the slope

step by step explaination: the line starts at -1 so that is the y-intercept. then you look for points on the graph that the line crosses which happens to be

(4, 2) and that's it.

Scientist A dissolved 1.0 kilogram of salt in 3.0 liters of water. Scientist B dissolved 2.0 pounds of salt into 7.0 pints of wa

solong [7]

The scientist that made a more concentrated salt solution is scientist A.

<h3>How to compute the value?</h3>

Since Scientist A dissolved 1.0 kilogram of salt in 3.0 liters of water. The concentration will be:

= 1/3 = 0.33

Scientist B dissolved 2.0 pounds of salt into 7.0 pints of water. The concentration will be:

= 2/7

= 0.285

Therefore, the scientist that made a more concentrated salt solution is scientist A.

For people doing some jobs, long spells of high pressure weather can bring problems. Give three examples of jobs that would be a

dolphi86 [110]

Answer:

Sports players: For people that need high respiratory performance, rises in the pressure may difficult the things, so they would be affected by high pressure because this makes breathing a little bit harder.

Workers in construction and such: People that work a lot with their muscles, in heat environments (road workers, construction workers) may be affected by the same problem as before, and this makes the workers to exhaust in a shorter time than if they worked in a lower pressure environment.

Scientist: A lot of time, some experiments or investigations need a specific pressure to work, so changes in weather pressure may affect investigations, and because the changes are actually uncontrollable, the scientist are really affected by them.

Olegator [25]

Answer:

Step-by-step explanation:

x / 100 = 0.2

Multiply both sides by 100 to isolate x. 100 x 0.2 = 20
