50 POINTS PLEASE HELP

Answer:

$perimeter= 5\sqrt{15} + 5\sqrt{5}$

Step-by-step explanation:

Given ,

A right angle triangle ΔABC with right angle at C and ∠A=30° and AC=5√5 units .

Let ∠A=A,∠B=B∠C=C and AC=b,BC=a,CA=b .

Implies perimeter of triangle = a+b+c .

now

$tanA=\frac{a}{b} \\\a=b*tanA\\a= 5\sqrt{5} *tan30^0\\a=\frac{5\sqrt{5}}{\sqrt{3}}$

and

$cosA=\frac{b}{c} \\\c=\frac{b}{cosA} \\c=\frac{10\sqrt{5}}{\sqrt{3} }$

implies ,

$perimeter = \frac{5\sqrt{5}}{\sqrt{3}} + 5\sqrt{5} +\frac{10\sqrt{5}}{\sqrt{3} }\\perimeter= 5\sqrt{15} + 5\sqrt{5}$

Arte-miy333 [17]

Answer:

4.5 minutes

Step-by-step explanation:

At time zero the level was 7 gallons and at time 3 min, the level was 5 gallons.

Take two points:

(0, 7) and (3, 5)

Find the rate of change:

m = (5 - 7)/3 = 2/3

This is a 2 gallons per 3 minutes

Tank holds 10 gallons, it was emptied by 3 gallons and it took:

3 : (2/3) = 3* 3/2 = 4.5 minutes

Answer:

$3 - a$

Step-by-step explanation:

Given that when you add two numbers together the result is 3.

The greater of the number is given as a.

Let "x" represent that lesser number.

Thus:

$a + x = 3$

To make x the subject of the formula. Subtract a from both x.

$a + x - a = 3 - a$

$x = 3 - a$

Therefore, the expression that represents the lesser number, x, is:

$3 - a$
