Answer = Red portion

Firstly, find out the area of the red portion (the area around the centre).

The three figures around the centre are trapeziums, so use the trapezium area equation.

a + b / 2 x h

4.5 + 5 = 9.5

9.5 / 2 = 4.75

4.75 x 1.5 = 7.125

As there are three trapeziums, times the area by 3.

7.125 x 3 = 21.375

Area of red portion = 21.375
—
Next, find out the area of the blue portion.

As the blue portion is in the centre and the figure at the centre is an equilateral triangle, use the equilateral triangle area equation.

root 3 / 4 x a^2

root 3 / 4 x 5^2 = 10.83 (rounded to 2 d.p)
—
Area of red portion = 21.375

Area of blue portion = 10.83

This means that the red portion has a greater area.

Hope this helps :)

The density of a fish tank is 0.4fish over feet cubed. There are 12 fish in the tank. What is the volume of the tank?

ololo11 [35]

Answer: $30\ ft.^3$

Step-by-step explanation:

Given: Density of tank = 0.4 fish over feet cubed.

We know that, $\text{Density}=\frac{\text{Mass}}{\text{Volume}}$

Therefore,

$\text{Volume of the tank}=\frac{\text{Mass}}{\text{Density}}\\\\\Rightarrow\ \text{Volume of the tank}=\frac{12}{0.4}\\\\\Rightarrow\ \text{Volume of the tank}=30\ ft.^3$

Hence, the volume of the tank = $30\ ft.^3$

What is 48,100,000,000,000 in scientific notation? 4.81×10−11 4.81×10−13 4.81×1011 4.81×1013

SSSSS [86.1K]

Given number is 4,8100,000,000,000.

In this number of zero is 11. So we can write it as $481 * 10^{11}$

But for scientific notation we will enter decimal after two place in reverse direction.For this we will also multiply number by 10^2.

So number will be $4.81 * 10^{11} *10^2 = 4.81 * 10^{13}$

So fourth option is correct.
