Find the area of an equilateral triangle with a side of 6 inches.

sweet-ann [11.9K]

Answer:

9 $\sqrt{3}$ in²

Step-by-step explanation:

The area (A) of an equilateral triangle is calculated as

A = $\frac{s^2\sqrt{3} }{4}$ ( s is the length of a side )

Here s = 6, thus

A = $\frac{6^2\sqrt{3} }{4}$ = $\frac{36\sqrt{3} }{4}$ = 9 $\sqrt{3}$ in²

If f(x) = V7x + 31 , find f(0).

Arte-miy333 [17]

Answer:

f(0) = 31

Step-by-step explanation:

We are given the following function:

$f(x) = \sqrt{7x} + 31$

f(0).

This is the value of f when $x = 0$ . So

$f(0) = \sqrt{7*0} + 31 = \sqrt{0} + 31 = 0 + 31 = 31$

So f(0) = 31

7. An aquarium is shown below. The

Mnenie [13.5K]

Answer:

1920 in³

Step-by-step explanation:

The volume of the water can be gotten by calculation the volume of the aquarium it fills/occupies.

Since the water fills to exactly three inches below the top of the aquarium, hence the height of the water in the aquarium is given as:

height of water = 13 in - 3 in = 10 in

Therefore the volume of the water in the tank is given by the formula:

Volume of water = height of water * breadth of tank * length of tank

Volume of water = 10 in * 8 in * 24 in = 1920 in³
