Answer:

h=40/4

40=h×4

Step-by-step explanation:

Step 1- Divide

<u>40</u>= <u>h×4</u>

4 4

10=h

*I'm not sure if this is a multiple choice question, but here are some equations that I came up with. Hope it helps! :)

Answer:

$y+2=-\frac{3}{2}(x-2)$

Step-by-step explanation:

Given:

Two points on a line are given as:

(0, 1) and (2, -2)

We know that the slope of a line passing through points $(x_1,y_1)\ and\ (x_2,y_2)$ is given as:

$m=\frac{y_2-y_1}{x_2-x_1}$

Plug in $x_1=0,y_1=1,x_2=2,y_2=-2$ . This gives,

$m=\frac{-2-1}{2-0}\\\\m=\frac{-3}{2}=-\frac{3}{2}$

The equation of a line with slope 'm' and points $(x_1,y_1)\ and\ (x_2,y_2)$ is given as:

$y-y_1=m(x-x_1)\\\\or\\\\y-y_2=m(x-x_2)$

Now, on plugging in the second point $(x_2,y_2)=(2,-2)$ we get:

$y-(-2)=-\frac{3}{2}(x-2)\\\\y+2=-\frac{3}{2}(x-2)$

Therefore, the first option is correct which is given as:

$y+2=-\frac{3}{2}(x-2)$

Line AB contains points A (−2, 6) and B (4, 5). The slope of line AB is −6 negative 1 over 6 1 over 6 6

kolezko [41]

To work out the slope of a line, you have to divide the difference in y by the difference in x

The difference in y = 5-6 = -1
The difference in x = 4--2 = 6

So, -1/6 is the answer

37% dextrose solution (37 mg per 100ml of solution) is given iv. Suppose a total of 3.81 liters is given over a 15 hour period.

sashaice [31]

Answer:

During 15 hour period, 1409.7 mg of dextrose will be delivered.

The flow rate of dextrose per hour will be 93.98 mg/hour.

Step-by-step explanation:

If a total of 3.81 liters of the solution is given over a 15 hour period.

Now, 1 liter is equivalent to 1000 ml

So, a total of 3810 ml of the solution is given over a 15 hour period.

If 100 ml of solution contains 37 mg of dextrose, then 3810 ml of the solution will contain $\frac{37 \times 3810}{100} = 1409.7$ mg of dextrose.

So, during the 15 hour period, 1409.7 mg of dextrose will be delivered.

The flow rate of dextrose per hour will be $\frac{1409.7}{15} = 93.98$ mg/hour. (Answer)
