the dashed line means you don't include any points on the line... and is represented by the inequalities > or < hope it helps

Linear inequality is a term that has to do with a linear function. These inequalities involve inequality symbols such as greater than >, less than <, ≤ is less than or equal to, ≥ is greater than or equal to


Dash boundary line indicates that the solution does not include any of the points on the line. So the answer is A.

Answer:

Step-by-step explanation:

2) r = 16/2 = 8 cm

Area of top and bottom = 2*πr²

= 2 * 3.14 * 8 * 8

= 401.92 cm²

Midlle part = h * πd

= 6 * 3.14 * 16

= 301.44 cm²

Total = 401.92 + 301.44

= 703.36 cm²

3) Area of front and back = $2* \frac{1}{2}*b * h\\$

$= 2*\frac{1}{2} * 3 * 4\\\\= 12 cm^{2}$

Area of bottom = length * breadth

= 12* 3

= 36 cm²

Area of left = 12 * 4

= 48 cm²

Area of right = 12 * 5 = 60 cm²

Total = 12 + 36 + 48 + 60 = 156cm²

A drainage basin bordering the sea has an area of 7500 km2 . The average precipitation for this drainage basin is 900 mm year-1

Alexxx [7]

Answer with Step-by-step explanation:

The basic water balance dictates that "Amount of water flowing into the basin should be equal to the amount of water flowing out of it".

Mathematically

$Water_{in}=Water_{out}\\\\P=E+Q+I$

where

P = precipitation

I = Infiltration losses in the basin

E = Evapotranspiration

Q = is outflow from the basin

Applying the given values we get

$900=E+\frac{22.5\times 10^{8}}{7500\times 10^{6}}\times 1000+100\\\\900=E+300+100$

Part b)

From the above equation we get

$E=900-400=500mm/year$

The evaporation in cubic meters per year is

$E'=0.5\times 7500\times 10^{6}=3750\times 10^{6}m^3/year$

Finger [1]

A= h (a+b)

solving for b:

Solve for b, i.e separate b in one side and the other terms in the other side

A = ah + bh

A - ah = bh

(A - ah) / h = b

$b= \frac{A-ah}{h}$

I hope that helps!
