2.32x10^8. I'm in Honors Chemistry in high school, I just inputted this into a calculator which is easy. Otherwise you can just take them out of scientific notation and into standard form which is this:
(160000000)(5800000)/4000000=232000000. And then convert it back.

The area of the parallelogram is simply the sum of the areas of the component three shapes - the square and the two triangles.

Area of square = 4.5 cm × 4.5 cm = 20.25 cm²

Area of two triangles = 2 ×(1/2) × 2.3 cm × 4.5 cm = 10.35 cm²

Area of parallelogram = 20.25 cm² + 10.35 cm² = 30.6 cm²

Go step by step to reduce the radical. <br> The square root of 96

lakkis [162]

Answer:

Step-by-step explanation:

We want to reduce the radical. In order to do that, we want to find the factors of 96 that are square numbers

The factors of 96 are:

$1, 96, 2, 48, 3, 32, 4, 24, 6, 16...$

16 is a square number, so we can rewrite

$\sqrt{96} = \sqrt{16*6} = \sqrt{16} * \sqrt{6} = 4\sqrt{6}$

If kenny earns 142% of Benny's Salary, how mucho more does Kenny earn than Benny

Sergeeva-Olga [200]

Let Benny's salary = $ K

But kenny earns 142% of Benny's Salary

So, Kenny's salary = 142%of K

Kenny's salary =K $\times \frac{142}{100}$

Kenny's salary = 1.42K

Kenny's income exceeds Benny's by =1.42K - K =$0.42 K

% by which Kenny's salary exceeds by Benny's = $\frac{0.42 \text K}{\text K} \times 100$

% by which Kenny's salary exceeds by Benny's = 42%
